National Organ Procurement Service Beaumont Hospital Dublin 9 Revised September 2011
2 GUIDELINES FOR ORGAN DONATION
Introduction The guidelines will hopefully enhance existing
The National Organ Procurement Centre for the Republic of Ireland is co-ordinated through Beaumont Hospital. The Co-ordinators provide a 24 hour on-call service to all hospitals around the country and are available at all times to facilitate the organ donation process. At present, the number of people awaiting transplantation greatly exceeds the number of organs available for transplant. This trend continues as the waiting lists continue to increase.

practice in identifying potential donors. It is very important that potential donors are identified and that every family is offered the opportunity to consider organ donation. These guidelines aim to provide information and support for healthcare professionals to ensure that families are approached about organ donation in a sensitive manner and at an appropriate time by skilled and experienced personnel. The guidelines will hopefully enhance existing practice in identifying potential donors and optimising the management of the organ donor to ensure organs remain viable for transplant.

Role of the Donor Transplant Co-ordinator The Co-ordinator is involved in the
The National Co-ordinators in Beaumont Hospital provide a 24 hour on-call to hospitals throughout Ireland, to deal with all enquiries regarding organ donation and provide a service to other transplant centres. This includes co-ordinating various retrieval teams involved with the procurement of organs and tissues.
DONOR REFERRALS 2000 - 2010
process from the initial enquiry right through to the donor in theatre. Ultimately our aim is to achieve this expediently with the least inconvenience to both the family and donor hospital. This is achieved by maintaining close contact and co-operation with the donor family, donor hospital and the retrieval teams. The Co-ordinator is involved in the process from the initial enquiry right through to the donor in theatre. Post the donation the co-ordinator will communicate with the donor family and all the staff involved in the care of the donor regarding the outcome of donation.
10 GUIDELINES FOR ORGAN DONATION
Approaching the topic of Organ Donation Every family should be given the option to consider organ donation. Studies have shown that asking about organ donation does not lessen the grief nor should it enhance it. Grief occurs because a loved one has died. It is important to talk to a patient’s family to ensure that those who wish to donate are not denied the chance to do so.
When to ask? The best time to raise the subject of organ donation can be between the two sets of brain stem tests. The family should be told what the tests involve, why they are being done, and given the prognosis. They should then be allowed time to come to terms with their situation before the question of organ donation is raised.
Who can ask? It could be any health professional within the intensive care unit who feels comfortable to do so and has a positive approach. It can be a nurse or doctor who has been caring for the patient and who has built up a rapport with the family. Allow the family time to discuss it privately and make their decision.
The family’s decision In the end, the decision rests with a patient’s closest relative. We are guided by their wishes. However, health professionals have an important role to play. Surveys show that 70% of people say they are willing to be donors. To do so, their relatives need to be asked.
GUIDELINES FOR ORGAN DONATION 11
Lack of Objection/Consent CORONER Relevant cases that are reported to the Coroner (under the Coroners Act 1962) should be referred in order to determine whether organ donation can proceed.
FAMILY Written consent for organ donation is obtained from the next of kin of every donor at the time of donation. Only organs that are specifically consented for are taken for transplantation. The Department of Health and Children have recommended that information surrounding social and sexual health have to be ascertained in order for transplantation to proceed safely. It may be appropriate for this discussion to include other key people such as extended family and friends. It is important to provide the family with the information leaflet on organ donation. Whilst recognising that this is a difficult time for families and knowing that these questions can seem insensitive, or even cause offense, the transplanting teams are responsible for minimising the risk of transmittable viral infections to transplant recipients. It is routine to carry out full virology screening on all potential donors. An in-depth social and medical history needs to be obtained. The family will be assured that they may change their minds about organ donation at any time.

as a positive aspect of their tragedy.
If it is a coroner’s case the coroner needs to be informed and his approval sought prior to the family being formally approached about donation.
The family can then be formally approached about organ donation and consent obtained if they are agreeable.
Information for donor families on Organ Donation and Transplantation (available in 12 different languages through Transplant Co-ordinators Office).
It may be helpful to ask the family if the patient held an organ donor card, or if there had ever been any discussion about organ donation and whether the patient had made their wishes known. Donation can help the family to cope as they see the donation of their loved ones organs as a positive aspect of their tragedy.
GUIDELINES FOR ORGAN DONATION 13
Sequence of events The Co-ordinator will be available to talk to the family and will organise the subsequent retrieval. The Co-ordinator usually meets with the family to obtain consent if required, and is available to come to the donor hospital to make the initial approach, following the confirmation of brain stem death. The role of the Co-ordinator is to facilitate the wishes of the donor and the donor family in carrying out their wishes and those of their loved one and to support the staff caring for the donor and family.
The family should be kept informed at all stages of the donation process. They may not wish to stay in the hospital but all families must have adequate time and privacy to say their goodbyes to their loved one.
Theatre time depends on local circumstances, the family wishes and theatre availability and may be delayed for local emergency operations. The donor is transferred to theatre with ventilatory and haemodynamic support maintained.
The surgery is performed by transplant surgeons and can take up to five hours for a multi-organ donation.
Utmost dignity and respect of the donor is maintained by all members of the transplant team throughout the whole donor process.
The family will be informed of the outcome of the transplant operations by the Co-ordinator who will write to them within a month of donation.
When the operation is complete the donor is cared for by the Co-ordinator and theatre team.
14 GUIDELINES FOR ORGAN DONATION
Donor Management Once Brain Stem Death has been confirmed, there is a shift in care from preserving cerebral perfusion to maintaining the organs for transplantation. Brain stem death leads to derangement of normal homeostatic mechanisms. For medical management of the organ donor, please refer to the Intensive Care Society of Ireland’s (ICSI) Guidelines and Diagnosis of Brain Death and Medical Management of the Organ Donor 2010, available from their website. www.icmed.com

GUIDELINES FOR ORGAN DONATION 15
Organ Donor Retrieval ◆ The retrieval of organs from a donor takes place, under aseptic conditions, in the operating theatre of the hospital in which the donor has died. The dignity of the donor is maintained at all times by every member of the retrieving team at every stage of the operation.
◆ Theatre availability is arranged by the Co-ordinator and the theatre staff in the donor hospital.
◆ The operating room is set-up as for a major surgical procedure with diathermy, two suction machines and extra drip stands for perfusion. The scrub nurse sets up a basic laparotomy set.
◆ The retrieval teams bring their own specialised perfusion and retrieval instruments, cooled perfusion fluid, perfusion technician and sometimes their own scrub nurse.
◆ Additional sterile trolleys will be required for perfusion, depending on how many organs are being retrieved. There may be up to four transplant surgical teams from different centres, i.e. heart/lung, liver, kidney/pancreas.
◆ The ventilated donor is transported from the Intensive Care Unit by the Anaesthetist accompanied by the Intensive Care Nurse who hands the patient over to the Theatre Nurse.
◆ The identity of the patient and consent for the procedure is checked by the ITU and Theatre Nurse.
◆ The transplant teams check consent, blood group and brain stem test records.
The sequence for the donor operation should be discussed with the Co-ordinator who is always available during the donor operation.

GUIDELINES FOR ORGAN DONATION 17
Surgical Procedure ◆
A midline incision is performed from the supra sternal notch to the pubic symphysis. A sternotomy is performed using Gigli saw. This allows maximum exposure of the organs within the thoracic and abdominal cavity. After the incision is made, a full laparotomy is performed. Each transplant team inspects the organs for any trauma, occult neoplasm, or intrinsic disease.
The heart and lungs are inspected for suitability. The ureters are isolated and the kidneys are mobilised on their vascular pedical. The liver is mobilised. The aorta is isolated and the main anterior branches i.e. the coeliac axis and the supra mesenteric artery dissected free.
The venous system is also isolated prior to dissection.
The great vessels of the chest are then isolated. The abdominal aorta is cannulated with a William Harvey cannula supplied by the team. The superior mesenteric artery via the portal vein is also cannulated. The aorta is cross clamped in the chest. In situ perfusion is commenced and ventilation is discontinued. The heart is perfused with cardioplegia. The intra-abdominal organs are perfused with U.W. solution (University of Wisconsin).
18 GUIDELINES FOR ORGAN DONATION
The sequence of Organ Removal ◆
The heart/heart lung is removed followed by the liver, the pancreas and then the kidneys are removed en bloc. Specimens of spleen and lymph nodes are removed for tissue typing purposes. Iliac vessels are also removed to necessitate liver transplant surgery.
On removal, each organ is separately perfused on a perfusion table by the team retrieving the organs. They are individually placed in double sterile bags, packed in ice and transported to the different transplant centres as quickly as possible. The kidneys are separated and marked right and left before packing.
A kidney perfusion machine called the Lifeport System is used on occasion for kidney preservation. This optimises the kidneys and reduces delayed graft function. This is also the preferred method of preservation in donors over 55 years or donors with a history of hypertension. The kidneys are biopsied and then placed on continuous perfusion by the transplant surgeon in theatre.
Heart valves may be retrieved if heart is found to be unsuitable for transplant.
After all swabs and instruments are accounted for by the scrub and circulating nurse, the incision is closed with a continuous suture material by the transplant team. The theatre staff and Co-ordinator will care for the body of the donor following organ retrieval. This can be an emotional time particularly as the donors are often very young, and although the theatre staff do not come in contact with the relatives of the donors, they still feel sympathy for their loss.
