Guidelines for the management of acute asthma in general practice for adults • Failure by clinical staff to use objective Many asthma deaths measurement of severity are preventable. • Patients or relatives failing to appreciate severity Factors leading to poor • Under-use of corticosteroids outcome include:

Assess and record: • Peak Expiratory Flow Rate (PEFR) • Heart and respiratory rate

• Oxygen saturation*

MILD

MODERATE

ACUTE SEVERE

PEFR >75 % previous best or predicted value NO features of acute severe asthma

PEFR 50 – 75% previous best or predicted value NO clinical features of acute severe asthma

PEFR ≤ 50% previous best or predicted value Can’t complete sentences, use of accessory muscles Respiratory rate ≥ 25/min Tachycardia ≥ 110, Previous ventilation Admit

• Air driven Nebulised Salbutamol 5mg or via spacer (salbutamol 100mcg 4-6 puffs given 1 at a time and inhaled separately)

Observe for 30 mins

Stable or improving PEFR > 75%

Not improving PEFR 50-75%

Improving and PEFR > 60%

Allow home • Prednisolone 40mg daily for 7 days • Review by GP/diploma-level practice nurse within 48 hrs • Supply relevant contact numbers

FOLLOW UP should include:• Review inhaler technique and understanding of medication • Provoking factors for uncontrolled asthma • Formulate or revise written selfmanagement plan with patient

• Prednisolone 40 mg orally Observe for 30 mins Reasons for admission: • Not improving or PEFR remains < 60% • Requires 2nd neb • Previous ventilation • Concern over social circumstances • Patient unable to assess / monitor own condition.

• Address potentially preventable contributors to admission • Issue patient education leaflet (such as Asthma UK’s ‘After Your Asthma Attack’)

• Oxygen 10-15 L/min a.s.a.p (to maintain SpO2 94-98% - pulse oximeter should be available) • Nebulised Salbutamol 5 mg • Prednisolone 40mg orally or if shock or GI tract disturbance Hydrocortisone 100mg IV • IV access • If no nebuliser available salbutamol 100mcg 4-6 puffs via spacer given 1 at a time and inhaled separately Contact hospital for admission. Arrange ambulance.

LIFE THREATENING Any of the following: PEFR<33% previous best or predicted value Quiet chest, Cyanosis Bradycardia, Exhaustion, Confusion, Hypoxia O2 Sat < 92% • Dial 999 for ambulance • Oxygen 10-15 L/min a.s.a.p (to maintain SpO2 94-98% - pulse oximeter should be available) • Nebulised Salbutamol 5mg & Ipratropium 0.5mg ideally via oxygen driven nebuliser • Venous access if possible: • IV Hydrocortisone 100mg • IV Salbutamol 250 -500mcg • If no nebuliser available salbutamol 100mcg 4-6 puffs via spacer given 1 at a time and inhaled separately

If further nebulised Salbutamol 5mg needed add Ipratropium Bromide 0.5mg or via spacer

• GP review within 48hrs • Hospital specialist asthma nurse or respiratory consultant review about a month after admission

Discharge home from hospital

ADMIT

Inhaled Bronchodilator via spacer device

* If low (<92%) urgent admission is required, but do not be reassured by a normal reading if other parameters indicate a severe or life-threatening episode.

• Symptoms and response to self treatment

Life threatening features: • Features of acute severe present after initial treatment • Previous near fatal attack

Repeat nebulised Salbutamol 5mg and Ipratropium 0.5mg or via spacer

• Lower admission threshold if afternoon or evening attack, recent nocturnal symptoms or hospital admission, previous severe attack, patient unable to assess own condition or concern over social circumstances
