In the spring of 2002 the Council of the Other authorities that include: The British Transplantation Society agreed that Intensive Care Society, The Association of the Standards Committee (Chair: Dr C G Anaesthetists, The Academy of Medical Newstead, Consultant Renal Physician, Royal Colleges and Faculties in Leeds Teaching Hospitals Trust) should conjunction with the Department of prepare guidelines relating to this topic. Health are preparing guidance on the Dr Newstead wrote the first draft in management of the patient who has the conjunction with Mr S Willis (Transplant potential to become a non-heart beating Co ordinator, Leeds Teaching Hospitals organ donor.

In the body of the document key points It was subsequently decided after are shown highlighted. discussion with a number of interested parties including The Council of the BTS that the BTS guidelines would be altered to cover the management of the process of donation after the diagnosis of death. It would in addition cover the areas of direct involvement of the "Transplant Team" both of the donor and evaluation of the patient who has the potential to become a donor. Excluded from this guidance therefore is the important contribution of other hospital staff for example those working in Accident and Emergency, Intensive Care as well as Coroners.

Additional points:

1) Younger donors with shorter warm ischemic times have better outcomes independent of the above variables. 2) Retrieval should be within ninety minutes of perfusion. 3) Cold ischemic time must not exceed 24 hours. 4) The position of the catheter balloons should be checked at retrieval.

Objective assessment of texture, colour, consistency and perfusion effluent on the back table are important parts of the assessment. 18 Primary non-function has significant adverse consequences. These are especially severe for the recipient of a life-sustaining organ such as a liver or lung

The principal purpose of viability testing is to reduce primary non-function

This is in the setting where there are other options for life sustaining therapy such as dialysis. These discussions are far from strait-forward, as for any individual there is a need to quantify the degree of "risk" associated with each course of action, in a situation where such quantification is almost impossible. Where the organ is the only life sustaining treatment then the patient's and medical team's options are clearly greatly constrained.

32 If historic peak or current positive cross match, recipients eliminated from consideration.

Step 5 Call in selected crossmatch negative recipients and repeat crossmatches with current sera (2-2.5h)

Or if decision made to call in prior to retrieval or prior to result of historic and current sera cross match known run cross match versus time of transplant sera when available. (2-2.5h)

Estimated total laboratory time ~ 8-10h
