FOREWORD

These two handbooks were written by a group of medical students of the University of Hong Kong (HKU) with the guidance from the academic staff of the Emergency Medicine Unit of the HKU. The students have formed an Emergency Medicine Interest Group with the vision of serving the community of Hong Kong through their knowledge in Emergency Medicine.

Ageing population is a worldwide phenomenon. It is expected that the proportion of people aged 65 or above would rise from 13% in 2011 to 30% in 2041 in Hong Kong. With increasing number of seniorcitizens in the community, how to best respond to their healthcare demands should be everyone’s concern.

These two handbooks aim at guiding the readers across the vast topic of first aid for an ill or injured elderly. It is primarily written for the caretakers of the elderly in the community. But readers other than the caretakers of the elderly may also find the two handbooks useful if they come across an elderly who is acutely unwell. These two handbooks are neither authoritative nor comprehensive. It is hoped that readers would pursue further study on the topics in which they are interested and help themselves better respond to an ill or injured elderly under their care.

The Emergency Medicine interest Group and the Emergency Medicine Unit would like to thank the ‘We Are With You’ Fund for the support in the production of these handbooks.

PROCESS OF AGEING

Muscle - Reduced muscle mass (30-40%) and muscle power - Becoming fatigue earlier and more easily during exertion - Lower regenerative ability - More fat in muscle tissue

Skin - Wrinkling and sagging especially on face, neck and hands - Getting thin and pale - Wounds heal more slowly or may not heal at all - Reduced sensitivity to cold - Reduced sweating - Reduced resistance to UV light damage

General - Decrease in body mass - Decrease in the proportion of body fat

Eyes - Yellowing of lens - Higher prevalence in cataract - Lower light sensitivity - Poorer dark adaptation - Reduced tear production - Minimal decrease of visual acuity at rest but significant decrease of visual acuity with a moving target

Nervous system - Slower central processing and longer reaction time - Reduced sensitivity to vibration especially in feet - Less sensitivity to temperature - Modest loss of neurons - Slight decrease in brain mass

Skeleton - Both men and women lose bone mass during ageing - Women have faster loss in bone mass, which accelerates after menopause - Men have slower bone loss, as they start losing other tissues as well - Higher prevalence of osteoporosis in both genders

Physiology/Anatomy of Ageing Ageing is a term to describe the changes in our body functions when we get older. The changes affect every body system and are affected by environmental and genetic causes. The following are changes that appear in our body during the process of ageing.

PROCESS OF AGEING

Heart and blood vessels - No change in heart rate and contraction force at rest - Less increase in heart rate and contraction force during exercise - Moderate increase in heart size - Stiffer heart and blood vessel tissues - Increased blood pressure

Digestive system - More stomach acid production - More common to have constipation - Reduced absorption of nutrients - Decrease in liver mass

Respiratory system (breathing) - Decrease in diaphragm strength - Decrease in lung volume and air flow rate - Increase in residual air in lungs

Other systems - Impaired shivering - Decrease in sensitivity of smell - Decrease in thirst drive - Deterioration of balance - Loss of hearing in high-frequency tones

Immune system - More prone to infection - Reduced response to vaccination

Kidney, urinary and genital systems - Decrease in kidney filtration function, concentration ability and dilution of urine - Decrease in kidney mass - Incomplete bladder emptying leading to increase in residual urine - Less intense orgasms (both men and women) - Longer resting time between orgasm and next erection for men

BASIC LIFE SUPPORT

Basic Life Support (BLS) Basic Life Support is the combination of emergency procedures needed to ensure a person’s survival, including cardiopulmonary resuscitation (CPR), control of bleeding, treatment of shock and poisoning, stabilization of injuries and/or wounds, and basic first aid. In this chapter, we will cover CPR, recovery position, and automated external defibrillator (AED).

Why Basic Life Support?

It is important to learn BLS because emergencies happen! There are a lot of things you can do with little or no equipment to deal with medical emergencies, and you could potentially save a life with these simple skills.

Why learn Bystander CPR? Because Bystander CPR is a simple and effective way to keep a person with sudden cardiac arrest alive. This is a series of actions to support the breathing and circulation of a person whose heart has stopped beating, and help maintain blood perfusion to the vital organs to a certain extent to buy time for more definitive treatment.

What is sudden cardiac arrest?

Sudden cardiac arrest (SCA) is when there is a sudden failure of the heart to contract effectively, so that the delivery of oxygen by blood to the body tissues, including the brain and the heart itself, is disrupted, or even stopped. This situation is very dangerous, and is one of the leading causes of death worldwide, especially in the elderly. The median age of SCA in Hong Kong is 80 years old. Two-thirds of the cases occur at home, and 40% occur witnessed. Yet, only about 30% of the elderly in Hong Kong get immediate CPR from a bystander.

This is very low compared to other developed countries, and many more lives could potentially be saved if more people step out to carry out CPR on an elderly with SCA.

How does Bystander CPR help?

Compression-only Bystander CPR

The Chain of Survival

CPR is one of the most important first aid techniques, it’s a series of actions to support the circulation of a person whose heart has stopped beating. This helps maintain blood perfusion to the vital organs to a certain extent to buy time for more definitive treatment.

The Chain of Survival is a closely packed series of five steps to keep the chances favorable for a SCA elderly to stay alive.

The steps are: 1) Early access to care (e.g. calling 999) 2) Early CPR 3) Early defibrillation (i.e. with an AED) 4) Early advanced care (by professionals) 5) Good post-resuscitation care Each one of these steps must be done well and early, and with the Bystander BLS routine, you will already be covering the first 3 key steps in saving the elderly. Here is how to do it.

CPR

AED

If you have not been trained in CPR, or do not wish to have mouth-tomouth contact with a stranger, you can do compression-only CPR. It is as effective as the conventional bystander CPR. The approach can be remembered with a mnemonic of :

Danger + Check + Call + Chest Compression

1 Danger

Check if the environment is safe for you and the elderly

2 Check

Check the elderly for Responsiveness: call the elderly; shake the elderly’s shoulders

3 Call

IF the elderly is not responsive AND not breathing properly, call for help by - Dialing 999 - Asking a bystander to take the nearby AED for you

Breathing: observe if there are chest movements; listen for any breathing sound

Proceed to CPR (C A B)

Compression-only Bystander CPR A. Position Place the heel of a hand on the breastbone at the center of the elderly’s chest.

C. Depth Using your body weight, press the elderly’s chest down hard for 5-6 cm (2 inches - 2.4 inches).

2

B. Posture Place the other hand on top of the first hand, and make your fingers interlocked.

Move your shoulders so that they are directly above your hands, keep your arms vertical and straight throughout. Do not bend them even as you apply pressure.

D. Frequency Press repeatedly and fast with the same posture at a frequency of 100-120 per minute. As a rule of thumb, run the song Staying Alive “Ha, ha, ha, ha, staying alive, staying alive…” in your head. Each beat roughly corresponds to one press.

Alternatively, follow the best of the song 急救進行中

x 100 - 120/mins

E. Recoil After each press, make sure you allow the chest of the elderly to recoil.

Repeat the procedure until - the elderly regains consciousness with normal breathing and heart rate - an ambulance has arrived - the AED has arrived - you are exhausted and cannot carry on.

If neck injury is suspected, jaw thrust can be performed instead.

B

B for Rescue Breaths After 30 chest compressions, give 2 breaths.

Place your mouth on the elderly’s mouth so that it is airtight, and blow steadily into his/her mouth.

Each breath must last about 1 second.

Observe to see if his/her chest rises. If so, the rescue breath is effective.

In conventional bystander CPR, the cycle between chest compressions and rescue breaths in a 30:2 ratio, in which 30 chest compressions are followed by 2 rescue breaths.

Repeat the procedure until - the elderly regains consciousness with normal breathing and heart rate - an ambulance has arrived - the AED has arrived - you are exhausted and cannot carry on.

Automated External Defibrillator (AED) Commonly called AED, the device has a daunting full name Automated External Defibrillator. However, its principles and use are actually not difficult to grasp.

Sudden cardiac arrest, in which the heart stops beating suddenly, can cause death within minutes if untreated. The 2 major causes of sudden cardiac arrest, both triggering irregular heartbeats, are ventricular fibrillation and ventricular tachycardia. The commoner cause is ventricular fibrillation, in which the lower chambers (ventricles) of the heart quiver quickly and irregularly. The other cause is ventricular tachycardia, in which the ventricles have regular, fast beats that lasts for a short period of time.

The AED can be used in this condition to assess the heart rhythm and restore it to normal by administering electric shocks to the heart. CPR also helps the chance of survival.

AED sets usually come with spoken or visual instructions for the untrained user and are easy to use. An important point, though, would be to make sure that no one is touching the elderly when the shock is being administered.

AEDs can be found in many public places, such as shopping malls, airports, hotels and schools. You can find them directly under these signs

AED It’s important for the local EMS system and Community members to know where AEDs are located in the community. In the event of a sudden cardiac arrest emergency, you can find AED quickly.

There are many different brands of AEDs, but the same basic steps apply to all of them.

Recovery Position If the elderly is unconscious without any suspected neck injuries and breathes spontaneously, he/she should be placed in the recovery position. The recovery position keeps the airway patent, and prevents the elderly from aspiration.

1. Kneel by the right side of the elderly.

2. Place the right arm of the elderly at right angle with his/her palm facing up.

6. Gently tilt the head back, and lift the chin (head-tilt and chin-lift), and perform the airway check of ABC again if you have not done so.

Stay with the person and monitor the elderly’s ABC continuously until an ambulance arrives.If the injuries are not too severe, turn the person to the other side after 30 minutes.

3. Hold the left hand of the elderly and place the back of the hand against his/her right cheek.

4. Grasp his/her left leg and bend to a right angle.

5. Keep his/her left hand on the right cheek. Pull the bent leg towards you to make the elderly roll to your side. His/her left arm should prevent the elderly from rolling too far.

CENTRAL NERVOUS SYSTEM

Stroke

Background

Stroke is a medical emergency. It occurs when the blood supply to the brain is disrupted, causing oxygen depletion and loss of function of the affected area. Strokes could be caused by either a clot in a blood vessel stopping blood passing to the brain or a burst blood vessel bleeds into the brain.

Stroke is more common in old age. It is associated with circulatory system disorders, such as high blood pressure.

Early recognition and hospital care (within 3 hours) may improve the chance of recovery.

In Hong Kong, nearly 3,000 people die of stroke each year. At present, it is the 4th fatal disease in Hong Kong. In general, people who suffer from a stroke are usually over the age of 50.

Symptoms and signs

A characteristic of acute stroke is that the symptoms and signs often come suddenly.

- Facial weakness - Limb weakness - Speech problems like slurring or inability to comprehend or express - Difficulty to swallow, maybe associated with drooling and easy choking - Headache, especially new or sudden - Nausea not accountable by other apparent causes - Reduced level of responsiveness - Numbness and tingling in face, arms or legs - Dizziness especially persistent, severe or unrelated to posture change - Loss of balance or inability to walk steadily - Blurred vision especially only one eye is affected - Loss of bladder or bowel control

As a first aider

- Recognize the symptoms and signs of stroke and arrange emergency help - Reassure and comfort the elderly to keep him or her calm Do’s The FAST test could be used to recognize stroke.

1. A Chinese mnemonic to remember the test is “微笑殭屍會說話“ a / Face (Facial weakness) - Ask the casualty to smile - If he has a stroke, he may only be able to smile on one side and his face may look uneven b / Arm (Arm weakness) - Ask the casualty to close his eyes and raise both arms - If he has a stroke, he may only be able to move one arm or has weakness on one arm c / Speech (Speech problems) - Find out if the casualty can speak clearly and understand your words - If he has a stroke, he may not be able to speak clearly or respond appropriately d / Time - If any of the signs are present, call 999 for emergency help - If possible, record the time the symptoms first appear 2. Reassure the elderly and keep him or her comfortable 3. Monitor the level of responsiveness, breathing and pulse until help arrives 4. If the patient becomes unconscious, check for pulse and breathing and start CPR if necessary Don’ts Give the elderly anything to eat or drink

Remarks

Transient Ischemic Attack (TIA) is commonly known as a mini stroke by the lay public. The symptoms and signs are similar to those of stroke. However, the symptom and signs are often transient and the elderly may recover within 24 hours. TIA is associated with a high risk of stroke in the subsequent days and weeks. Those elderly with features suggestive of TIA should obtain immediate medical consultation despite the recovery from the initial symptoms and signs.

Seizure

Background

Seizure consists of involuntary muscle contractions due to disturbance in electrical activity of the brain. It presents with sudden loss of consciousness and jerking of the extremities in most cases. In rare cases, consciousness is preserved.

In elderly, the most common causes of seizure include epilepsy, Alzheimer’s disease, stroke and medication. Seizure can also be caused by head injury, brain-damaging disease (neurodegenerative diseases, tumor, and infection), and lack of nutrients in brain (hypoglycemia, acute alcohol intoxication or drug withdrawal)

Symptoms and signs

- Sudden loss of consciousness - Arching of back - Breathing difficulty (grey-bluish lips, red and puffy face/neck) - Convulsive movements (clenched jaw with noisy breathing, tonguebiting, drooling or foaming of saliva, facial twitching) - Urine or bowel incontinence - Tiredness and sleepiness after seizure The elderly may have brief warning symptoms (aura) just before seizure, for example, strange dizzy feeling, and special smell/taste. He/she may regain consciousness in a few minutes, and may be unaware of the actions.

! ! ! ! !

- Look for red flags and manage as medical emergency - Protect the seizing elderly from injury - Maintain a patent airway and smooth breathing during and after the seizure when the elderly is not fully conscious Do’s 1. Seek emergency medical help as soon as possible 2. Protect the elderly - clear away any potentially dangerous objects to prevent injury of the elderly, pad the area with clothing or pillows if the elderly is close to wall or hard objects, ask bystanders to keep clear 3. Protect the head and loosen tight clothing around neck 4. Lie the elderly down in recovery position (if not suspecting a spinal injury) 5. Monitor closely the responsiveness level and breathing; open airway 6. Note the time of onset and duration of seizure 7. Check for any injuries and apply necessary first aid Don’ts 1. Move the elderly unnecessarily 2. ut anything in his mouth or attempt to restrain him or her during a seizure 3. Give food and drinks

Head Injury

Background

Symptoms and signs

Falls account for the majority of head injury cases in elderly. Serious head injuries are often a result of traffic accident. In the elderly, an apparently trivial head trauma may lead to complications not commonly seen in the young. Intracranial bleeding is the most worrisome complication. What’s more important to note is the onset of the intracranial bleeding may be delayed and may go unrecognized for months until the elderly suddenly deteriorates or becomes symptomatic.

It is usually not difficult to recognize the symptoms and signs of an acute head injury. There may be a wound or swelling on the scalp and the elderly may complain of pain. For those elderly who cannot express themselves properly, very often the injury is only incidentally noted.

The elderly with acute complication as a result of the head injury almost always appear unwell and may appear different from their usual status. On the other hand, those with delayed complication are difficult to recognize. Sometimes, they may be able to recall that there was a head injury or the injury was so trivial that they forget it.

One of the most well-known delayed complication in the elderly is called ‘subdural hematoma’. It means that there is blood collection beneath the dura covering the brain surface. The symptoms and signs are often subtle. For example, the elderly may appear more and more forgetful, with unexplained personality change or non-specific dizziness and headache. A high index of suspicion is needed.

Central Nervous System

One of the objectives of first aid for an elderly with acute head injury is to look for clues suggestive of post-injury complication, in particular, intracranial bleeding.

Red flag sign: ! Clear fluid or watery blood ! from nose or ear ! Bruise around eyes ! ! Increasing drowsiness ! ! Confusion ! ! Impaired consciousness ! ! Memory impairment ! ! Weakness ! ! Numbness ! ! Worsening headache ! ! Repeated vomiting ! ! Convulsion !

- Look for the red flag signs - Protect the elderly from further injury

As a first aider

Do’s For those with red flags or you are not sure about the clinical status of the injured elderly: 1. Seek emergency medical help immediately 2. Provide BLS if needed 3. Provide basic wound care if there is a wound 4. Regularly monitor the vital signs including responsiveness, breathing and pulse until medical help is available For those without red flags and you are confident that the injured elderly is stable and well: 1. Observe for at least 24 hours from time of injury for any abnormal symptoms. Seek medical consultation as soon as possibleif there is persistent dizziness, worsening headache, repeated vomiting, twitching or anything that worries you.

Common Head Injury Symptoms / Post-Concussion Syndrome (PCS) Physical Symptoms: - Headache, Dizziness - Sensitive to noise & visual disturbance - Fatigue

Cognitive Symptoms: - Memory problems - Poor concentration - Judgement problems

Behavioural Symptoms: - Depression - Anxiety & Stress - Irritability

2. Ensure there is a responsible adult who can observe the elderly Whenever there is doubt, seek medical consultation as soon as possible.

Don’ts Give food and drink to the injured elderly with red flags.

Depression and Suicide Background

Depression is one of the commonest psychiatric disorders in old age. Yet, it is frequently unrecognized. In Hong Kong, the prevalence of depressive disorders in elderly is 9.7%, compared to 8.4% in adults aged 18-65 years old.

Depression is a known risk factor of suicide, and suicide risk increases with age. The suicide rate in the general population of Hong Kong is around 10 to 13 per 100 000, whereas the rate in the age group of 65 and above is around 30 per 100 000, and in the age group of 75 or above is 50 per 100 000. The ratio of the male to the female suicide rate in the elderly is 1.3 to 1. Compared to other countries, the elderly suicide rate in Hong Kong is relatively high.

Symptoms and signs

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) of the American Psychiatric Association, the definition of depression is: Anyone who has 5 or more of the following symptoms, including at least one of the first two symptoms, nearly every day for at least 2 weeks - An usually sad mood - Loss of enjoyment and interest in activities that used to be enjoyable - Lack of energy and tiredness - Feeling worthless or feeling guilty when they are not really at fault - Thinking about death a lot or wishing to be dead - Difficulty concentrating or making decisions - Moving more slowly or sometimes becoming agitated and unable to settle - Having sleeping difficulties or sometimes sleeping too much - Loss of interest in food or sometimes eating too much Risk factors - Family history - Being female - Disability and illness (especially if serious) - Old age home residents - Bereavement - Social isolation - Chronic pain - Sensory impairment (e.g. hearing or sight)

The most important red flag in a depressed elderly is suicidal tendency. It is commonly found in those institutionalized, or those with chronic illness or disability.

The elderly suffering from depression may think that the future is so hopeless that suicide is the only way out.

Following an attempted suicide, further attempts — and successful suicide — are common.

Suicidal tendency may be overt or covert.

Overt manifestations include: ! Intentional drug overdoses (opiates, antidepressants, ! paracetamol, benzodiazepines; more common in women) ! Self-injury (hanging, shooting, jumping, drowning; ! more common in men) Covert features are especially common in older people, and include: ! Social withdrawal ! ! Severe self-neglect ! ! Refusal of food, fluid, ! or medication

As a first aider

- Approach the depressed elderly and assess whether there is any immediate suicidal risk. Immediate suicidal risk is suggested by strong and frequent suicidal ideation or presence of a suicide plan. However, the absence of which is not equivalent to a lower risk. If the person has an immediate risk of committing suicide or the situation is beyond control, seek medical help immediately, or simply call 999.

- Provide emotional support to the person and encourage him or her to get appropriate professional help if there is no immediate risk.

- Whatever the situation is, always ensure that support and attention is readily available to the elderly.

Do’s 1. Listen non-judgmentally.

2. Express empathy to the elderly.

3. Take every suicidal idea or expression seriously 4. Seek professional help whenever possible Don’ts 1. Leave the elderly with suicidal risk alone. If you cannot stay with them, you must arrange someone else to do so, for example, a family member or friend who has agreed to help.

2. Ignore any idea of suicide, no matter how casual the elderly expresses it.

CARDIOVASCULAR SYSTEM

Hypertensive Emergency Background

Hypertension is one of the most common chronic illnesses in elderly in Hong Kong. A study by the School of Public Health of the University of Hong Kong in 2012 revealed that about 1 in 3 adults in Hong Kong has hypertension, and almost 50% of elderly are suffering from the disease.

When the heart beats, blood is pumped into arteries. Blood pressure is the pressure against which blood pushes the arterial walls. Blood pressure readings are given in two numbers, written as 120/80 mmHg. The first number is called the “systolic pressure” or “upper pressure”, which is the pressure exerted on the arterial walls when the heart contracts.

The second number called the “diastolic pressure” or “lower pressure” is the pressure exerted on the arterial walls when the heart relaxes.

Hypertension is a reading of blood pressure greater than 140 (higher pressure) over 90 (lower pressure) mmHg with repeated

measurements when the person is resting. Systolic hypertension is a common condition in elderly.

When blood pressure spikes to a dangerous level that can potentially cause organ damage and other complications in the body, it is a hypertensive emergency. The blood pressure has to be lowered to avoid imminent organ damage.

High blood pressure can have adverse effects on the brain, heart, kidneys and eyes.

Hypertensive emergencies generally occur at blood pressure levels exceeding 180 systolic OR 120 diastolic, but can occur at even lower levels in people whose blood pressure has not been previously high.

In elderly, forgetting to take blood pressure medication and interactions between medications are the common scenarios to trigger hypertensive emergencies.

Some, however, do not have any underlying causes.

Symptoms and signs

In most cases of hypertension, there are no symptoms present.

However, in cases of hypertensive emergencies, the following signs and symptoms may occur: - Severe chest pain - Shortness of breath, that may be increasing - Intense headache - Nausea and vomiting - Blurred vision - Increasing confusion - Numbness/weakness - Difficulty speaking - Seizures - Tinnitus - Fainting episodes - Unresponsiveness

- Recognize the signs and symptoms of hypertensive emergency - Seek emergency medical help

As a first aider

Do’s 1. If the elderly has BP > 180/120 mm Hg and with the above symptoms and signs: - Seek emergency medical help 2. If the elderly is unconscious: - Check for airway, breathing and pulse and perform CPR if necessary 3. If the elderly is conscious: - Help the elderly into a comfortable position, usually sitting - Calm and reassure the elderly 4. If the elderly is vomiting or having seizures: - Put the elderly in recovery position to prevent aspiration and seek emergency medical help 5. If the elderly complains of difficulty in breathing: - Prop him/her up using pillows behind upper back and seek emergency medical help Don’ts Wait for the blood pressure to drop down on its own when symptoms occur

Angina

Background

Heart disease is the 2nd killer disease in Hong Kong after cancer. Coronary heart disease is a major type of heart disease.

Incidence and prevalence of ischemic heart disease rise with age. As many as 30% of people aged >65 years in the developed world have angina or myocardial infarction (MI) and a further 30% have covert (asymptomatic) disease.

Angina is a sensation of chest pain typically squeezing or pressure like due to ischemic heart disease. When the coronary vessels become narrowed, the blood supply of heart muscle may be impaired. This is aggravated on exertion when oxygen demand increases.

Heart attack occurs with severe occlusion of coronary vessel leading to heart muscle death. However, it is not unusual for the elderly to have silent ischemia.

Risk factors for cardiovascular diseases include hypertension, hyperlipidemia, diabetes mellitus, smoking and family history of angina or cardiac muscle infarction. The untreated ischemic chest pain can cause cardiac muscle infarction, complicated by sudden cardiac death, shock, acute decompensated heart failure or congestive heart failure.

Syncope

Background

Syncope is a sudden, transient loss of consciousness due to reduced and inadequate cerebral perfusion. The incidence of syncope increases with age. Some studies showed that as many as a quarter of institutionalized elderly had this problem and the recurrence rate could be as high as 30%. The elderly is unresponsive with a loss of postural tone (ie slumps or falls). In the majority of cases, they would regain consciousness spontaneously. Secondary injury like hip fracture may occur as the elderly loses consciousness and fall. Syncope is not a disease by itself. It is a manifestation of an underlying disorder that causes reduced cerebral perfusion. Some of the important causes are: 1.Transient hypotension caused by the upright posture, straining, or coughing which is exacerbated by low circulating volume (dehydration or bleeding somewhere), hypotensive drugs or concurrent illnesses. Orthostatic hypotension (lower blood pressure on standing than lying down) is the most common cause of syncope.

2. Vasovagal response to pain, fright, emotion leading to slowing of heart beat and then hypotension.

3. Heart diseases such as myocardial infarction, arrhythmia, and aortic stenosis (narrow aortic valve opening)

Symptoms and signs

- Loss of consciousness - Pale, sweaty, absent or very weak carotid pulse - Reduced muscle tone - Possible tongue biting - Possible incontinence - Brief (few seconds) seizure activity - Brief (minutes) period of confusion may occur - Recovery is usually brisk and spontaneous

! Prolonged loss of consciousness ! Irregular pulse ! Chest pain or palpitation before or after the syncope ! Seizure or confusion ! Incomplete recovery of consciousness ! Recurrent syncope within a short period of time

Shock

Background

Shock means that cells cannot get enough oxygen and nutrients due to various causes. Shock is life-threatening and requires immediate medical treatment.

The outcome is more unfavourable in elderly because of poor body reserve in general.

Examples of shock and their causes Types Common causes Hypovolemic Shock

Massive bleeding or dehydration

Cardiogenic Shock

Heart attack

Anaphylactic Shock

Food allergy, insert bite

Septic Shock

Severe infection

Any type of shock can be fatal.

Symptoms and signs

- Dizziness, drowsiness, confusion - Chest discontent or tightness - Shortness of breath - Reduced urination - Cold & clammy skin **When shock is suspected, call 999 immediately. There is no effective way to handle shock at home. **

THORAX

Acute Asthmatic Attack Background

Asthma is a small airway disease that causes airway obstruction due to bronchoconstriction (constriction of the airway) and increased sputum production. It is most commonly triggered by allergens exposure.

Asthma among older adults are common and can be serious.

Although many people have their first episode of asthma at young age, asthma can happen in any ages including elderly. Unlike their younger counterparts, the elderly are more likely to develop severe health problems Chronic Asthma with Airway Remodeling Incresed fibrosis Increased muscle thickness Increased mucus Increased inflammatory cells (CD4 and eosinophils) Effect of Inhibiting NF-kB on Airway Remodeling Decreased fibrosis Decreased muscle thickness Decreased mucus Decreased inflammatory cells (CD4 and eosinophils) Mild Asthma Minimal fibrosis Minimal muscle thickness Minimal mucus

(for example, respiratory failure) even during mild asthma attack.

The condition rarely resolves itself and remains as a disabling disorder to the advanced age.

Diagnosis of asthma in elderly may be missed due to the masking effect from other illnesses, such as heart disease and emphysema. The less active lifestyle of elderly compared to a young person also lowers the chance of provoking acute asthmatic symptoms (e.g. wheezing and breathing problems).

Choking

Background

Symptoms and signs

Choking occurs when the elderly’s airway is partially or completely blocked by a foreign body. The foreign body causing choking is commonly a food bolus, though it can be anything like a broken denture. The elderly is prone to choking for various reasons. Their chewing mechanism may be impaired because of dental problem.

Swallowing is also affected because of pre-existing stroke. A demented elderly is also at risk because of loss of coordination of mastication and swallowing.

Abdominal Pain Background

Abdominal pain in an elderly can be caused by a variety of conditions. Most of the time, it is caused by simple food poisoning, gastroenteritis or cramps.

abdominal pain often presents late to a hospital. Also, they usually present at a more severe stage and require hospitalization (50-60%) or surgical treatments (20-33%).

However, “acute abdominal pain”, defined as an abdominal pain of less than 6 hours of onset, must be treated with caution. Elderly with acute

Recognize red flag signs and manage as medical emergency

As a first aider

Do’s 1. Reassure the elderly and help him or her in a comfortable position 2. Sit him or her up if there is severe vomiting 3. Heat pad may help ease the pain 4. Seek emergency medical help in case of red flag symptoms or you are in doubt of the elderly’s condition Don’ts Offer food or drinks if medical emergency is suspected (the elderly may require an emergency surgery)

Remarks

Generally speaking, abdominal pain is a non-specific symptom.

It can be caused by benign and serious conditions. Atypical presentation is not uncommon in the elderly. Abdominal pain is no exception. For example, an elderly harboring a serious pathology may only experience mild abdominal pain initially and then suddenly deteriorates. We should never underestimate the seriousness of the symptom of abdominal pain in the elderly.

Vomiting

Background

Vomiting is commonly caused by gastroenteritis, food poisoning and motion sickness.

However, some conditions such as outbreak of norovirus in institutions, gastroesophageal reflux disease, appendicitis, intestinal obstruction, metabolic

disturbance, head injury, cancer and many others can also cause vomiting. Drugs such as opioids and chemotherapy can induce vomiting. When caring for a vomiting elderly, it is important to prevent dehydration and look out for underlying causes.

Constipation

Background

Constipation refers to difficulty in passing stools. It can be caused by inadequate fiber or fluid intake, inadequate physical activities, intestinal diseases or diseases such as overactive parathyroid, scleroderma (a connective tissue disease), Parkinsonism, stroke and diabetes. Medications such as antacid and overuse of laxatives can also cause constipation.

Constipation can be complicated by fecal impaction, in which the rectum becomes filled with large, dried and hardened masses of stool that cannot be passed. It may be further complicated by precipitating urine retention.

Dehydration

Background

Symptoms and signs

If the excess water loss from vomiting and diarrhea is not promptly replenished, an elderly may develop dehydration. Dehydration can begin to develop when a person loses as little as 1% of his body weight through fluid loss. Without prompt treatment, the elderly may develop shock.

- Dry mouth & dry eyes - Dry and/or cracked lips - Thirst - Headache (lightheadedness) - Dark urine - Reduced urine output - Cramping

Common causes of dehydration include excessive sweating (exercise, fever, hot weather), diarrhea, vomiting and excessive urine output due to medical conditions. Elderly with chronic diseases such as diabetes, heart failure, and kidney diseases is prone to dehydration.

Hot humid weather, physical disability and negligence by caretaker are also risk factors.

- Recognize red flag signs and manage as medical emergency - Rehydrate and monitor hydration status

As a first aider

Do’s 1. Give fluid to drink. Water is usually sufficient but oral rehydration solutions can help with salt replacement.

Oral Rehydration Salt Oral rehydration therapy is the administration of fluid by mouth to prevent or correct the dehydration that is a consequence of diarrhoea. In addition to water replenishment, oral rehydration solution is designed to replace the lost ions and correct any underlying acid-base imbalance due to excess water loss.

Oral rehydration salts are available commercially. Alternatively, they can be prepared at home with simple ingredients. When preparing oral rehydration solution, you MUST follow the instructions on the packet. Adding too much or too little water may worsen the patient’s condition.

How to make Oral Rehydration Solution from Salt & Sugar a / Wash your hands b / Measure 1 litre of drinking water into a clean container c / Measure 1 levelled teaspoon of SALT and 8 levelled teaspoons of SUGAR into the water. (A levelled teaspoon is where the salt or sugar is FLAT in the spoon, NOT piled up) d / Mix the salt and sugar into the water well until you cannot see the salt or sugar at the bottom of the container e / Taste the solution. It should never taste very salty. DO NOT boil up this solution once it is made up f / Give the drink to the elderly with diarrhoea

PELVIS AND PERINEUM

Acute Retention of Urine Background

Urinary retention is the inability to empty the bladder. Urinary retention can be acute, chronic or acute on chronic.

Acute urinary retention in men becomes more common with age and peaks at their 50s-60s.

In men 40 to 83 years old, the overall incidence of urinary retention is 4.5 to 6.8 per 1,000 men. For men in their 70s and 80s, the overall incidence increases to 100 per 1,000 men and 300 per 1,000 men. The risk factors for male urinary retention are kidney stones, prostatitis, benign prostate hypertrophy, and prostate cancer.

In female, acute urinary retention is less common. It can happen if the bladder sags or moves out of the normal position (cystocele) or is pulled out of position by a sagging of the lower part of the colon (rectocele). The risk factors for female urinary retention are history of kidney stones, history of urinary tract infections, and those with recent gynecological surgery.

The causes of acute urinary retention can be classified into extramural, mural and intraluminal.

Extramural obstruction can be caused by an enlarged prostate in male, any pelvic masses pressing against the bladder or urethra and constipation.

Mural causes can point to weak bladder muscle or masses arising from the bladder wall.

Intraluminal causes include stones in urethra, urethral stricture and tumor at bladder neck or urethra. Acute urinary retention can also be caused by urinary tract infections leading swelling or irritation, nervous problems interfering with signals between the brain and the bladder, spinal cord problems and medications such as those used in flu, cough or nausea and vomiting.

In most cases, the bladder has to be drained by passing a small catheter through the urethra in the emergency department. At the same time, any known precipitating factors have to be corrected, like the medications mentioned above have to be stopped. In other cases where a reversible factor is found, a catheter may not be required. For example, if the urinary retention is caused by fecal impaction, the elderly should be able to pass urine once he or she opens the bowel.

Urinary Tract Infection Background

An urinary tract infection (UTI) is an infection in any part of the urinary system — kidneys, ureters, bladder and urethra.

Most infections involve the lower urinary tract — the bladder and the urethra.

Women are at greater risk of developing a UTI than men.

Infection limited to bladder can be painful and annoying.

However, serious consequences can occur if a UTI spreads to kidneys and blood stream.

The annual incidence of UTIs in the elderly is around 10% and it may be as high as 30% for those living in nursing homes and other institutions.The mortality rate in bacteremic elderly patients with UTI is as high as 33%.

In severe urinary tract infection, other systemic manifestations may arise, including high fever, shaking and chills, nausea, vomiting, palpitation, dizziness and even collapse. It can also be complicated by kidney damage and renal failure.

Different types of UTI may result in different signs and symptoms, depending on the part of urinary tract affected.

Symptoms and signs

Do’s 1. Seek emergency medical help call 999 in case of severe infection with systemic symptoms. For a severe UTI, you may need treatment with intravenous antibiotics in a hospital 2. Give paracetamol as indicated to lower body temperature and decrease pain 3. Take the entire course of antibiotics prescribed by doctor to ensure that the infection is completely gone 4. Drink plenty of water to dilute urine and keep bladder empty 5. Wipe from front to back after urinating and after a bowel movement in female. This helps to prevent bacteria in the anal region from spreading to the vagina and urethra Don’ts 1. Use potentially irritating feminine products. Using deodorant sprays or other feminine products, such as douches and powders, in the genital area can irritate the urethra 2. Drink coffee, alcohol, and soft drinks containing citrus juices and caffeine until your infection has cleared

EXTREME TEMPERATURE TOO HOT

Heat Exhaustion Background

Heat exhaustion occurs when a person exposed to a hot environment and sweating cannot dissipate the heat generated within the body. It may also occur if a person lives in a hot environment without adequate air circulation and does not drink an adequate amount of water.

The elderly are at a greater risk for heat exhaustion because of their underlying medical conditions (for example, poor circulation, skin changes, and chronic medication usage) which may limit the ability to sweat.

The risk factors for heat exhaustion in elderly include extreme hot weather, medications (such as antidepressants, antipsychotics, and tranquilizers which may impair the ability of the body to sweat), alcohol consumption, and overweight.

Symptoms and signs

- Excess sweating - Headache - Dizziness - Confusion

- Nausea & vomiting - Muscle weakness and cramps - Rapid, weak pulse

! Signs of progression into heat stroke !

- Lower body temperature - Replace body water and salts

As a first aider

Do’s 1. Stop any physical activity immediately 2. Rest in a cool, shaded area 3. Provide casualty with cool electrolyte water and sports drinks 4. Monitor casualty’s level of response, hydration status 5. Seek further medical help if casualty does not recover, unable to drink or whenever you are in doubt

Heat Stroke Background

Heat stroke is a medical emergency. It is the most severe form of heat illness in which the body temperature of a person is greater than 40.6 °C (105.1 °F). Due to environmental heat exposure the body temperature can rise rapidly and may lose its ability to cool down by sweat. When the body temperature reaches 40°C, the hyperthermia effect with systemic involvement including central nervous system will result. Heat stroke can cause death or permanent disability if not treated promptly.

Elderly are more vulnerable to hyperthermia as their adaptation ability to sudden changes in temperature is reduced with ageing.

In addition, they are more likely to suffer from chronic medical conditions and receiving medications that can change normal body responses to heat.

Hot and humid weather, dehydration and poorly ventilated room are the risk factors for heat stroke in elderly.

Symptoms and signs

As a first aider

- Hot, dry skin - Lack of sweating - Headache - Dizziness, drowsiness, obtundation

- Confusion, seizure - Nausea & vomiting - Muscle weakness and cramps - Rapid, weak pulse

- Recognize the condition and manage as medical emergency in all cases of heat stroke - Cool down the temperature of the elderly - Rehydrate the elderly Do’s 1. Seek emergency medical help, call 999 immediately 2. Rest in a cool, shaded area 3. Remove unnecessary clothing 4, Cool the elderly by fanning or wetting the skin with water 5. Rehydrate patient orally only if fully conscious and able to swallow 6. Monitor the elderly’s level of response until help arrives

EXTREME TEMPERATURE TOO COLD

Hypothermia Background

Hypothermia is defined as having a core body temperature below 35 °C (95 °F). It is most commonly caused by prolonged exposure to low temperature and inadequate clothing in cold weather. It can also be caused by impaired thermoregulation mechanism of the body.

Moderate Hypothermia (28-32°C /82.4-89.6°F) - Vigorous shivering - Cold, pale skin - Slurred speech Severe Hypothermia (<28°C /<82.4°F) - Shallow and slow breathing - Weak and slow pulse - Confusion - Shivering may stop - Unconsciousness

EAR NOSE THROAT

Nose Bleeding Background

Bleeding can arise from any part of the nasal cavity. The most common site of bleeding is from the anterior part of the nasal septum. The so-called Little’s area.

It bleeds when tiny blood vessels on the mucosal surface of the nostrils rupture. Very often, it is a result of trauma like nose pricking or forceful sneezing. Sometimes it is a symptom of another disorder.

For instance, nose bleeding may be a manifestation of high blood pressure. Of course, the most worrisome cause is malignancy.

Among southern Chinese, nasopharyngeal cancer is a Posterior ethmoid artery

Anterior ethmoid artery

Little area (Kiesselbach plexus)

Sphenopalatine artery

Superior labial artery

Greater palatine artery

diagnosis every doctor would consider.

Elderly commonly experience nasal bleeding. Some statistics showed that they accounted for 29-50% of cases of nasal bleeding. In the elderly with nasal bleeding, a secondary cause must be sought especially if the bleeding is unprovoked.

Nose bleeding becomes an emergency when it is not controlled by simple pressure or it is prolonged and massive.

An elderly may become very ill if a lot of blood is lost from nasal bleeding. Massive blood loss from the nose can lead to death.

Ear, Nose, Throat

Below are some of the causes of nose bleeding: Local causes - A blow to the nose - Sneezing, picking or blowing the nose - Rhinitis - Tumor (rare) Systemic causes - Bleeding disorder, use of anti-clotting drugs (eg: aspirin, NSAIDs, warfarin, Plavix) It is associated with older age, hypertension and dry weather.

Symptoms and signs

- Bleeding from nostril, on one side or both - Blood stained sputum and saliva when blood from the nose drips down to the pharynx posteriorly - Nausea and vomiting if a lot blood is swallowed - Bloody tear because of the communication between the nose and eyes via the nasolacrimal duct - Dizziness and other signs of blood loss, especially the amount of blood loss is great

! Nasal bleeding that is ! unprovoked, prolonged, recurrent, or massive ! Associated symptoms of ! abnormal nasal discharge, hearing impairment, headache and neck swelling

- Stop or reduce blood loss - Maintain a patent airway and avoid aspiration of blood

As a first aider

Do’s 1. Reassure and keep the elderly calm 2. Sit the elderly up and tilt the head forward to allow the blood to drain from nostrils 3. Ask the elderly to breathe through mouth and pinch the soft parts ( just below the nasal bridge) of nose for up to 10mins.

基本生命 支援術

基本生命支援術 (BLS) 「基本生命支援術」包含多個急救程序，如心肺復甦術、控制出血情況、治療休克、 中毒、穩定受傷和/或傷口狀況，及施以基本急救。其他項目會在稍後的章節中討論； 在此章節中，我們將主要討論的是心肺復甦術、復原臥式狀況及自動體外心臟去顫器 之使用方法。

心肺復甦術 復原臥式

自動體外 心臟去顫器

為什麼認識基本生命支援術? 認識基本生命支援術是非常重要的，因為意外及危急情況隨時發生！事實上，在只有少 量設備或沒有任何設備的情況下都可以處理緊急醫療情況。只要認識這些簡單技巧，任 何人都可以拯救別人寶貴生命。

為什麼要學習旁觀者心肺復甦術？ 施行旁觀者心肺復甦術既不複雜，又能確保提高突發性 心臟驟停患者的存活率，有關系列之動作能支援突發性 心臟驟停患者維持其呼吸及血液循環，並有助保持血液 通往各大器官，讓其換取更多時間，獲得更多治療機會。

患者平均年齡 有目擊者在場

71.5 50% 獲得用心肺復甦術協助

15%

突發性心臟驟停是什麼? 突發性心臟驟停(SCA) 是指心臟突然不能有效收縮，不 能提供血液輸送氧氣到身體各組織器官，包括大腦和心 臟本身出現擾亂，或甚至停止情況。這種情況非常危 險，而這亦是全球人口中，引發死亡的主要原因之一， 而在長者人口中情況更為顯著。在香港，突發性心臟驟 停患者平均年齡為 71.5 歲，約三分之二的病例發生在 家中，當中50%是有目擊者在場。可是只有 15%的患者 獲得旁觀者施以心肺復甦術等協助；與其他已發展國家 相比，這數字是非常之低。故此，只要更多市民願意認 識及學習施行心肺復甦術，將可拯救更多突發性心臟驟 停患者的生命。

旁觀者心肺復甦術如何幫助?

按壓式心肺復甦術

生存鏈

假如施援者沒有受過心肺復甦術的訓 練，或不希望跟陌生人口部接觸，你 可以嘗試施行按壓式心肺復甦術。 這跟常規的旁觀者心肺復甦術一樣 有效。

可以下列口訣謹記施行步驟：

生存鏈緊密串連，涵蓋五大步驟，為突發性 心臟驟停患者增加存活機會。步驟如下: 1. 及早尋求協助（如撥打999） 2. 及早施行心肺復甦術 3. 及早進行除顫程序（即配合自動體外心臟 去顫器急救） 4. 及早提供專業護理（由專業人員處理） 5. 良好及後護理 上述每一個步驟必須及早完成。按旁觀者心 肺復甦術常規，施援者已施行首3個關鍵步 驟。下列展示有關應用步驟：

1 2 3

評估現場 + 檢查 + 電話求援 + 胸部按壓

1 評估現場 2 檢查

評估現場環境，對施援者及長者是否安全

檢查長者 反應： 呼叫長者；搖動長者的肩膀

呼吸： 觀察長者胸部，看其有否出 現呼吸異常；或檢查長者有 否發出任何呼吸聲音

3 電話求援 如果長者沒有反應及呼吸異常，要立刻尋求援助，如： － 撥打 999 － 要求旁人協助，把自動體外心臟去顫器（AED）送達現場 進行胸外按壓

4 胸外按壓

按壓式心肺復甦術 胸外按壓 假如施援者訓練充足及具備信心檢查脈搏，可用兩隻手指放在患 者頸部前側，檢查其脈搏情況。

A. 位置 施援者跪在長者身旁，將一隻手放在長 者胸骨中心。

C. 深度 利用體重，用力向下按長者的胸部約 5-6厘米（2英寸以上） 。

B. 姿勢 再將手置於另一隻手上面，將手指緊扣， 雙臂保持垂直，謹記施壓時不可彎曲雙臂。

D. 頻率 重複及快速按壓，速率約每分鐘 100-120次。

x 100 - 120/分鐘

E. 回彈 確保每次按壓後，長者胸腔有足夠回彈。

重複此過程直到 － 長者恢復意識，有正常的呼吸和心跳 － 救護車抵達 － 自動體外心臟去顫器被送達現場 － 施援者累極並不能繼續

常規旁觀者心肺復甦術 與按壓式心肺復甦術施行之方法類似，可以下列口訣記着有關方法：

B - Rescue Breaths 人工呼吸 每30次按壓，進行人工呼吸2次 施援者與長者進行口對口吹氣時，應盡量使口部密封並緩緩吹氣 每次吹氣至少持續1秒 假如長者的胸部回復上升，這次人工呼吸便是有效

在常規的旁觀者心肺復甦術中，胸外按 壓和人工呼吸的比例為30：2，即30次 按壓，然後2次人工呼吸，然後30次按壓 ⋯⋯

重複此過程直到 － 長者恢復意識，有正常的呼吸和心跳 － 救護車抵達 － 自動體外心臟去顫器被送達現場 － 施援者累極並不能繼續

自動體外心臟去顫器（AED） 它的原理和使用技巧其實並不難掌握。

突發性心臟驟停患者，其心臟突然停止跳 動。假如患者在數分鐘內得不到治療，可 引發死亡。 突發性心臟驟停（SCA）主要有兩大成因， 但都涉及心臟不規則跳動，也被稱為心律 不正。最常見的成因是心室纖維性顫動 （V-FIB） ，即下心室顫動快速而不規則。 另一個原因是心室撲動，這是指心室 持續在短時間內快速跳動。 在這種情況下，自動體外心臟去顫器 （AED）可以幫助心律及心跳恢復正常。 心肺復甦術亦有助增加生存機會率。 自動體外心臟去顫器在公共場所非常普 及，如商場、機場、酒店、學校亦有安 裝。只要根據這些圖象指示，便可找到。

AED 它是本地緊急醫療系統（EMS）不可缺少的 一環，社區成員知道其位置所在亦十分重 要。在遇上突發性心臟驟停的情況，市民 亦可以快速找到自動體外心臟去顫器。

市面上充斥不同品牌的自動體外心臟 去顫器，但使用步驟都是大同小異。

復原臥式 如果長者不省人事，但其頸部沒有受傷及仍然可呼吸，這情況下應以復原臥式擺放長者 的身體。這樣可以防止任何口腔分泌或嘔吐物阻塞長者之呼吸道，確保其呼吸暢通。

1. 跪在長者右方。

2. 屈曲長者的右手，使其手肘成90度平 放在地上。

6. 頭向後仰，頦向上翹。 假如先前沒有為長者暢通氣道 + 施行人工呼吸 + 心肺復甦術，現在應該進行有關步驟。

保持監測長者的氣道 + 呼吸，直到救護人員到達。 如果長者情況不太嚴重，在30分鐘後可轉動身體到另一側。

3. 握住長者左手並使其手背貼在臉頰。

4. 提起長者的左腿，使其膝蓋屈成90度。

5. 讓長者的左手貼近右臉頰，抓緊其膝蓋，彎曲其腿部，拉向施援者，使長者轉向右 邊。施援者可利用長者的手臂，以防長者滾動。

中樞神經 系統

中風 中風是一種嚴重急症。這病症是指供往大腦的血液受阻，引致腦細胞 缺氧受損，並失去功能。

背景

隨年齡增加，中風情況愈趨普遍。而中風常與血液循環系統疾病有 關，如高血壓。 及早識別和盡快入院接受治療（宜於3小時內） ，可提高康復機會。 在香港，每年近三千人死於中風，而它亦是全港排行第四的致命疾 病。一般來說，中風患者通常是超過50歲的人士。 中風成因如下： － 有血塊凝在血管中，阻塞血液流入大腦 － 血液突發性地大量湧入腦部

症狀

— 面肌無力 — 手臂無力 — 說話困難 — 頭痛 — 噁心 — 反應遲緩 — 臉部、手臂、腿麻痺或癱瘓 — 暈眩，身體平衡不協調 — 視線模糊 — 失禁

中樞神經系統

— 確認中風的症狀，安排緊急救助 — 安撫和慰問傷者，直至救援人員到達

急救員目標

應該 快速測試以識別傷者是否中風 1. 中文版 — 測試是否中風 口訣「微笑殭屍會說話」 a / 面（面肌無力） ·叫傷者微笑 ·如果傷者中風，只能以半邊臉微笑，臉部看起來不對稱 b / 手臂（手臂無力） ·叫傷者閉目及提起雙臂 ·如果傷者中風，只能夠提起一隻手臂或手臂顯得乏力 c / 語音（語音問題） ·檢查傷者能否清楚說出並理解你的說話 ·如果傷者中風，未必能夠清楚地說話或做出合理的反應 d / 時間 ·如果發現任何跡象，立即撥打999作緊急求助 ·在情況許可下，應記錄最早出現的症狀及病發時間等 2. 安撫傷者，讓傷者處於舒適狀態 3. 監測傷者之反應水平，呼吸和脈搏，直致救援人員到達 避免 1. 給傷者飲食

備註

具體案例 短暫性腦缺血發作（TIA） TIA是指輕微中風。與一般中風情況類似，但症狀僅持續數分鐘，而 傷者情況將逐漸改善，及後亦會恢復狀態。傷者應尋求醫生專業意 見。一般情況下，治療方法跟治療中風類近。

癲癇 － 大腦電波活動過度活躍，身體及肌肉受其干擾，不自主收縮起來 － 意識突然喪失和四肢抽搐

背景

在極少數情況下，患者意識可得以保留。 原因 － 癲癇症 － 阿滋海默症 (其中一種老人痴呆症) － 中風 － 頭部受傷 － 腦損傷性疾病（如神經退化疾病、腫瘤、感染） － 曾中風或出現低血糖之情況，讓大腦缺乏吸收營養 － 酗酒/濫用藥物

症狀

－ 突然出現神志不清 － 肢體僵直或彎曲 － 呼吸困難，嘴唇呈灰藍色，臉部和頸部顯得紅腫 － 出現連串痙攣動作，例如：牙關緊閉、呼吸嘈雜、面部抽搐、 咬舌頭、流口水，甚至口吐白沬等 － 大、小便失禁 － 發病過後到完全清醒時，患者通常無法回憶發病經過 － 發病過後，患者感到疲倦和昏昏欲睡 － 在癲癇症發作之前，可能有短暫的警告期（先兆） ，例如： 突然產生奇怪的感覺，嗅到特殊的氣味

抑鬱症狀 及自殺 背景

在香港，18至65歲的人口群組中約有8.4％人口患有抑鬱症；而老年 人的患病率更高，約為9.7％，每10萬人當中有10至13人自殺。 隨著 年齡增加，自殺的風險亦隨之增加，65歲或以上長者群中，每10萬 人當中有30人自殺，而75歲或以上長者群中，每10萬人當中有50人 自殺。而在性別分組中，男性和女性長者的自殺率比例為1.3比1。因 此，與其他國家比較，本港普遍年齡群組的自殺率相若，但其長者自 殺比率顯然較高，女性自殺比率亦不容忽視。 抑鬱症是其中一種最為常見的老人精神疾病，可惜很難被診斷出來， 患者因而經常得不到合適的治療。其實只要有合適治療及作預防措 施，老人的抑鬱情況亦可得到改善。

中樞神經系統

27

中樞神經系統

根據美國精神醫學學會的《精神疾病診斷與統計手冊》 （DSM-V） ，抑 鬱症的定義為：

症狀

任何人具有下列5項或以上的 症狀，而當中包括第1或第2個 症狀，並持續出現最少2星期。 － 情緒低落 － 對事物失去興趣 － 缺乏體力和疲勞 － 覺得自己沒有價值， 過份自卑或自責 － 不想生存 / 產生自殺念頭 － 難以集中精神或作出決定 － 行動較慢，心情煩躁， 易發脾氣 － 睡眠困難，有時睡眠過多 － 厭食或過量進食

風險因素 － 家族遺傳 － 女性 － 殘疾人士和疾病患者 （特別針對情況嚴重者） － 居住在老人院的長者 － 經歷喪親之痛 － 社交孤立 － 慢性疼痛病患 － 感官受損／障礙（如聽覺或視覺）

如長者有自殺傾向，這為辨別其患上抑鬱症最明確 的訊號。抑鬱症的長者可能會認為未來是非常絕望 而自殺是唯一出路。普遍來說，患者會不斷反覆嘗 試自殺，直至自殺行動成功為止。 自殺行為可以分為「明顯自殺」或「隱藏自殺」。 明顯自殺行為包括： ！ 濫用藥物（如阿片類藥物、抗抑鬱藥、 ！ 對乙酰氨基酚、苯二氮䓬；常見於女性身上） ！ 自殘（如吊頸、吞槍、跳樓、跳海；常見於 ！ 男性身上） 隱藏自殺行為在長者群組中 較為常見，包括： ！社交恐懼 ！ ！嚴重缺乏自我價值 ！ ！拒絕飲食及藥物治療 ！

急救員目標

－ 接觸，評估和協助有自殺危機的人。如果發現高危人士，應立即 尋求醫療幫助。 － 提供情感上的支持，並鼓勵尋找專業人士的協助。 應該 1. 聆聽 2. 表現同理心 3. 直接詢問抑鬱症長者關於自殺的想法和評估其決定自殺危機的 嚴重性 4. 對於一個自殺的人，你應該： ·告訴他，你是關心及想幫助他 ·明確指出，抑鬱症是可以透過藥物治療的，給予長者希望 5. 應該直接詢問關於自殺的想法，例如可以問： ·「你是否有自殺的念頭？」或 ·「你是否想殺死自己？」 6. 要確定自殺危機的嚴重性，你應該直接問有關自殺的計劃， 例如可以問： ·「你已決定如何自殺？」或 ·「你決定何時會這樣做？」或 ·「你有沒有採取任何措施來實行自殺計劃？」 7. 愈深層次的計劃表示自殺風險愈大，但這絕不代表沒有計劃 安排的人沒有風險。故此，必須認真對待長者所有自殺的想法 避免 1. 將有自殺傾向的長者獨留自處。如果不能和他們在一起，必須 安排別人代替陪同，例如家庭成員或朋友等

高血壓急症

背景

在香港，高血壓是最常見的老人 慢性疾病之一。根據2003至2004 年度的人口健康調查顯示，15歲 及以上的人口中，27.2%受訪者 患有高血壓。年紀愈長則愈容易 患上高血壓，15至24歲群組的患 病率為5.2%，而75歲或以上的長 者群組更高達73.3％。

老年收縮期高血壓在長者群組中 是常見的情況。

心臟跳動時，血液便會泵入動脈。 血壓是指血液推向動脈壁時產生 的壓力。血壓讀數中有兩個數 字，標記為120/80毫米汞柱；第 一個數字為「收縮壓」或「上壓 力」，這是代表施加在動脈壁時 心臟收縮的壓力，第二個數字為 「舒張壓」或「下壓力」是代表施加 在動脈壁時心臟放鬆的壓力。

高血壓急症一般發生在血壓水平 超過180（上壓力）或120（下壓 力） ，但對部分長期處於較低血壓 者而言，亦可能在上述準則的情 況下病發。

高血壓是指當人體處於休息狀態 下並經多次量度後，血壓指數 高於140（上壓力）90（下壓力） 毫米汞柱。

高血壓急症是指，當血壓尖峰到 達危險程度時，有機會引起器官 受損或其他併發症的情況。而在 這情況下，必須立即降低血壓， 以避免器官受損傷。

對長者而言，下列原因均可能導 致高血壓急症： — 忘記服用血壓藥物 — 藥物之間可能發生的相互作用 — 大多數是突發性 （沒有根本原因）

症狀

在某些情況下，高血壓是沒有任何症狀，而一般情況下，會出現下列 跡象和症狀： － 劇烈胸痛情況 － 出現呼吸急促情況增加 － 劇烈頭痛 － 噁心和嘔吐 － 視野模糊 － 神智愈來愈混亂 － 麻痺/虛弱 － 說話困難 － 癲癇發作 － 耳鳴 － 昏厥 － 反應遲鈍

－ 辨識高血壓急症的症狀和徵兆 － 尋求緊急醫療救助

急救員目標

應該 1. 如果患者血壓高於180/120毫米汞柱和對主要器官造成傷害 （如神經系統、心血管、子癇前症等） － 立即撥打999，尋求緊急醫療幫救助 2. 如果患者昏迷︰ － 檢查其氣道、呼吸和脈搏，如有需要便施行心肺復甦術 3. 如果患者意識清醒： － 幫助患者處於舒適狀態，通常是讓其坐下來 － 保持冷靜，安撫患者 4. 如果患者出現嘔吐或抽搐： － 以復原臥式安頓患者，以防止其出現窒息情況 5. 如果患者出現呼吸困難： － 可用枕頭支撐患者背部，幫助呼吸 避免 1. 讓患者行走。假如患者必須行走，便須小心協助，以防其跌倒 2. 讓患者進食 ／喝水 3. 讓患者飲用任何含有咖啡因或酒精的飲料

在香港，心臟疾病繼癌症之後 已成為第二號殺手。而冠狀動 脈心臟疾病是心臟疾病的主要 成因。 隨年齡增長，冠狀動脈心臟疾 病（IHD）的發病率大大提高。 在已發展國家中，超過30％的 65歲或以上人士是死於心絞痛 或心肌梗死（MI）和另外30％ 轉化成沒有明顯徵狀的疾病。 心絞痛患者會感到胸痛，如有 擠壓或壓迫感覺，這是由缺血 性心臟疾病引起。隨著冠狀血管變窄，心臟供血肌肉可能受損害。當 需氧量增加時，這情況更會加劇。 當冠狀動脈血管嚴重受阻時，心臟肌肉便會死亡，即心臟病發。 然而，長者普遍會出現輕微缺血情況。 引發心血管疾病的危險因素眾多，包括高血壓、高脂血症、糖尿病、 吸煙和具有家族成員患上心絞痛或心肌梗死之病史。如缺血性胸痛未 得到適當處理的話，可引起心肌梗死、心源性猝死、休克、急性失代 償性的心力衰竭或充血性心力衰竭。

急性哮喘

背景

哮喘是一種慢性氣道疾病，由於支氣管收縮（氣道收縮）、痰量增加及 積聚，導致患者的氣道受阻並出現呼吸困難。接觸過敏原是最常見誘 發哮喘的成因。 哮喘在中老年人中是常見的病患，亦可導致嚴重後果。不少人在少年 時曾試過哮喘病發，但事實上任何年紀的人皆有機會患上哮喘，長者 亦不例外。即使只是輕度哮喘發作，長者卻容易因哮喘得到更嚴重 的健康問題，如呼吸衰竭。而這病很難治癒，對長者的健康影響更 甚。 長者哮喘絕不容易察覺，常有延誤確診的情況，不少長者因心臟疾病 和肺氣腫掩蔽效應而錯過及早求醫的機會。長者生活方式不太活躍， 使年輕一輩減低察覺長者患上急性哮喘症狀的機會。

腹痛 造成老人腹痛的原因眾多，但普遍情況皆是由較溫和的原因引起，如 食物中毒、腸胃炎或痙攣。

背景

「急性腹痛」定義為少於6小時發病的腹痛，如遇上這情況，必須立即 處理。然而，普遍長者延誤求醫，在很晚期及情況非常嚴重的情況才 到醫院求診，大大增加對住院治療或手術治療的需求。 以下為長者群（超過55歲）急性腹痛最常見成因： 1. 膽道疾病 2. 盲腸炎 3. 腸阻塞 4. 消化性潰瘍 5. 憩室炎

位置

左上方 － 消化性潰瘍

右上方 －膽道疾病

左下方 －憩室炎 －腸阻塞

右下方 －盲腸炎

疾病

症狀

膽道感染（BTI） （包括膽囊炎、膽管炎） 年老病患者之發病率和死亡率更為明顯。年 齡超過70歲的長者中，過半數患有膽結石， 高達20％的患者更會出現併發症。而患上 嚴重膽道感染的長者，更會出現血流感染 （BSI） ，約8％至20％為社區性菌血症。對年 老病患者而言，繼泌尿道感染後，膽道感染 是第二種最常引起敗血症的原因。

症狀 － 在用膳後，右腹上方 持續劇烈疼痛達數 小時，疼痛感覺可 能延至右側肩胛骨 － 噁心 － 嘔吐 － 尿液帶茶色 － 發熱 － 發抖

盲腸炎 － 初期圍繞肚臍位置 每人一生約有7%機會患上盲腸炎（每15人當 出現絞痛，6小時 中有1人患病） ，發病率為每10萬人當中有10 後轉移到右下腹 人。在長者群組中，發病率約為5％至10％。 － 噁心和嘔吐 － 便秘 假如盲腸炎患者得不到及時合適的治療，這 － 發燒 樣便會造成嚴重後果，甚至死亡。假如不及 早處理，發炎的闌尾可能破裂並化膿流入腹 腔，引起腹膜炎，而闌尾破裂率可高達70％ 以上；而長者的死亡率更較年青人高16倍。 故此，向長者灌輸「延誤診斷盲腸炎將會導 致高死亡率和發病率」的概念是非常重要。 腸阻塞 當腸道部分被阻塞，就會引起腸道蠕動（波 浪狀運動） ，出現絞痛狀況。如果阻塞情況持 續，腸壁便會受到傷害。情況更甚的，腸道 會出現破穿的情況。在長者群組中，腸梗塞 通常由結腸癌、憩室症和糞便嵌塞引起。

－ 腹部絞痛 － 腹脹 － 便秘 － 嘔吐

消化性潰瘍 － 腹部中上方/左方感 「消化性潰瘍」是指胃或小腸被侵蝕，多由幽 覺疼痛 門螺旋桿菌感染和長期使用非類固醇抗發炎 － 疼痛感覺短暫，情 藥NSAID所引起的。而這疾病引發的併發症 況持續數天至數星 眾多，如腸道破損、出血或便秘。如長者長 期不等 期服用非類固醇抗發炎藥NSAIDs或類固醇， － 吃辛辣食物會加劇 更大大增加其腸道破損及出血的風險 。腸道 疼痛感覺，飲牛奶 破損是一種外科急症，如果不及時治療，便 則可以舒緩有關 有機會發展到危及生命的腹膜炎。 情況 － 用膳約2小時後出 現疼痛感覺

急性尿瀦留 （尿滯留） 背景

「尿瀦留」是指膀胱無法清空尿 液。而此症可以分為急性或慢 性，當中急性尿瀦留是屬於急症 一種。 男性： 通常50 至60歲，大部分個案是由 於前列腺腫大引起。 女性： 個案多是因膀胱出現下垂、移位 （膀胱膨脹）或直腸出現下垂、移 位而引起。 流行病學 隨著年齡的增加，男性出現尿瀦 留的情況變得越來越普遍。 － 在40至83歲的男性群中，每 1,000人中，有4.5至6.8人病發。 － 約70歲的男性群中，每1,000 人中，有100人病發。 － 約80歲的男性群中，每1,000 人中，有300人病發。 在女性羣中，出現尿瀦留的情況 則不太常見。

風險因素 男性： － 腎結石 － 前列腺癌 － 前列腺炎 － 良性前列腺肥大 女性： － 曾患腎結石 － 曾患上尿道感染（UTIs） － 孕婦 － 近期曾接受過婦科手術 成因 － 尿道受阻塞 ．前列腺肥大 ．膀胱結石 － 尿道狹窄 － 由感染引起腫脹或刺激作用 － 神經系統出現問題，大腦和膀 胱信號失效 － 膀胱肌肉乏力 － 便秘 － 服食藥物，如抗組胺藥、抗柏 金遜症藥物及咳嗽藥水等

症狀

急性尿瀦留可能出現以下症狀，如發現便須立即求醫： － 排尿乏力 － 疼痛，急須排尿 － 下腹部感疼痛或不適 － 下腹腹脹 尿瀦留引起的併發症： － 尿道感染 － 膀胱受損 － 腎臟受損

尿道感染 尿道感染（UTI）意指任何的泌尿系統部位受感染，包括腎臟、輸尿 管、膀胱和尿道。

背景

大多數感染個案涉及下尿道部位，即為膀胱和尿道。 婦女患上尿道感染的風險比男性高。如患者膀胱受到感染，會感到 明顯痛楚。然而，如果尿道感染擴散至腎臟和血液的話，後果便會 相當嚴重。 在一般長者群中，受尿道感染的發病率約為10％，住在老人院或療 養院的長者則有高達30％的發病率，而長者因尿道發炎引發菌血症 的死亡率則高達33％。 不同的尿道部份受感染，都會有不同的症狀

症狀

泌尿道部分影響

症狀和徵兆

腎臟（急性腎炎）

－ 上背部和兩腰（側面）疼痛

膀胱（膀胱炎）

－ 出現盆腔腫脹 － 小腹不適

尿道（尿道炎）

－ 排尿時有灼熱感

尿道感染不常出現症狀，徵兆亦 不明顯，但當發生下列情況時便 須多加留意： － 經常有強烈便意 － 小便時有燒灼感 － 尿頻，但每次只排出少量尿液 － 尿液混濁 － 尿液帶血，呈紅色、鮮粉紅色 或可樂色 － 發出強烈氣味 － 女性會出現盆腔疼痛

併發症 1. 嚴重感染（如尿膿毒症） － 高燒 ．發抖、發冷 ．噁心 ．嘔吐 － 心跳急促 － 頭暈 － 暈倒 2. 腎受損 3. 腎功能衰竭

中暑

背景

當人處於炎熱環境，而排汗又不足以消散體內潛熱，中暑便會發生。 另外，在炎熱及空氣流通不足的環境下，如沒有足夠的水份補充， 也可能出現中暑的情況。老人中暑多因身體狀況問題而削弱了排汗能 力，包括循環不暢、皮膚變化，以及服用慢性藥物。 風險因素 － 極端高溫天氣 － 服用藥物，如抗抑鬱藥、抗精神病藥和鎮靜劑，均可能損害身體 的排汗能力 － 飲酒 － 超重

症狀

－ 出汗過多 － 頭暈 － 噁心、嘔吐 － 脈搏快速且細弱

－ 頭痛 － 精神錯亂 － 肌肉無力和痙攣

！患者病情惡化 ！開始有心絞痛跡象

！ ！

－ 幫助患者降低體溫 － 幫助患者補充水分和鹽份

急救員目標

應該 1. 立即停止任何涉及體力勞動活動 2. 在陰涼地下休息 3. 為患者提供冰涼的水電解質液和運動飲料 4. 監測患者反應，為其補充水份 5. 如果患者不能復原或不能飲水，應立即尋求醫療協助

嚴重中暑

背景

嚴重中暑屬於急症情況 。這是最嚴重的身體過熱病症。因外在環境因 素及身體缺乏調節下，體溫上升至40.6℃ （105.1° F） 。 身體的溫度迅速 上升，不能及時排汗，導致體溫無法下降，便會發生嚴重中暑的情況。 由於體溫升至40℃以上，高溫會影響身體功能系統，包括中樞神經系 統。如不及時治療嚴重中暑的情況，可引致死亡或終身殘廢。 對於溫度的突然變化，普遍長者的適應能力較差，故此他們更容易受 到高熱症影響 。如長者患有長期疾病及服食藥物，也會影響身體對 高溫作出反應及調節。 風險因素 － 高溫及潮濕天氣 － 脫水 － 房間通風不足

症狀

急救員目標

－ 皮膚乾燥、發熱 － 頭痛 － 精神混亂 － 肌肉乏力和痙攣

－ 排汗極少 － 頭暈 － 噁心及嘔吐 － 脈搏快速而微弱

－ 辨識患者狀況及施以急救治療 － 幫助患者降溫 － 幫助患者補充水分 應該 1. 撥打999，尋求緊急醫療援助 2. 安排患者到陰涼地方休息 3. 脫去患者不必要的衣服 4. 運用下列方法使患者降溫 a / 風扇 b / 用水潤濕皮膚 5. 只有在患者完全清醒及能吞嚥的情況下，使用口服補水溶液 6. 監測患者反應，直到救援人員到達

體溫過低

背景

「體溫過低」是指體內溫度低於攝氏35度（華氏95 度） 。長期處於低溫環境而保暖衣物不足，是體溫 過低最常見的成因。另外，溫度調節機制受損亦會 釀成體溫過低的情況。

在香港，每年約有10至20宗長者嚴重低溫症個案。

30 29 28 27 26

體溫過低

重度： （<攝氏 28度） － 呼吸淺而慢 － 脈搏緩慢，微弱 － 神智不清 － 發抖情況可能暫停 － 失去意識

31

重度

中度： （攝氏28-32度） － 劇烈的顫抖 － 皮膚冰冷，顯蒼白 － 言語不清

32 中度

輕度： （攝氏33-35度） － 發抖 － 高血壓 － 脈搏急促 － 呼吸急促

輕度

對長者而言，短暫處於寒冷天氣或輕微溫度下降， 足以令其體溫出現過低情況。

風險因素 － 患有慢性疾病，如糖尿病、甲狀腺功能減退 － 患者行動不便，如中風、老年癡呆症 － 飢餓 － 營養不良 － 酗酒或濫用藥物，如安眠藥、阿片類藥物

症狀

鼻出血

背景

鼻腔內任何部份均有機會出血， 而當中最常見的位置是鼻中隔。 當鼻腔內微小的血管出現破裂情 形，便會發生鼻出血的情況。 另 外，身體內系統性的疾病亦會導 致鼻出血的情況。鼻出血情況有 時會難以控制或停止，並導致低 血容量休克及死亡。 據統計，長者鼻出血情況非常普 遍，約佔百分之29％至50％。當 中，長者在後鼻腔部分出血情況 是比較常見，而這情況亦是較難 控制及處理。

成因 局部性 － 鼻子受到撞擊 － 打噴嚏，挖鼻過深 － 鼻炎 － 少數由腫瘤引起 全身性 出血性疾病，及曾使用抗凝血藥 （如阿士匹林、非類固醇抗炎類 藥、華法林、氯吡格雷等） 鼻出血亦與年老、高血壓和乾燥 的天氣等因素有密切關係。

症狀

－ 鼻孔出血 － 高血壓 － 亦有可能引起貧血和低血壓等情況 － 身體其他部位出現出血性疾病

！大量出血 ！出血不止 ！有休克跡象 ！有嚴重傷勢跡象 ！有出血性疾病及使用 抗凝血劑跡象

！ ！ ！ ！ ！

－ 辨識到危險訊號和施以急救處理 － 運用急救方法控制鼻出血情況

急救員目標

應該 1. 讓病人坐下來並將頭部向前傾，以便血液從鼻孔流出 2. 要求傷者用口呼吸，用手按壓鼻樑下的位置約10分鐘 1

2

3. 用乾淨的布或紙巾抹去血液 4. 放置一個冷敷 ／冰袋在鼻樑上方或； 利用潔淨的紗布或藥棉，填塞前鼻孔 5. 如果出血情況持續，再按壓10分鐘 6. 如果出血停止，病人仍須繼續向前傾斜，利用微溫清水清潔鼻子 7. 避免施力或擤鼻涕，以免阻礙血液凝固過程 8. 如果出血情況重複出現，需要再次用手於有關位置施予壓力 避免 1. 讓患者仰後頭部，以避免血液倒流至喉嚨，誘發嘔吐或窒息 2. 讓患者說話、吞嚥、咳嗽、吐痰或用力吸氣，因為有關動作可能 擾亂血液凝固過程
