Organ Dysfunction and Failure Following Brain Death Do Not Preclude Successful Donation

Area of Science:

• Transplantation Medicine
• Organ Donation
• Critical Care

Background:

• Organ dysfunction is a common challenge in donors after neurologic determination of death (NDD) before organ procurement.
• Identifying reliable markers for graft success is crucial for optimizing organ transplantation outcomes.

Purpose of the Study:

• To investigate the relationship between the pathophysiology of donors after neurologic determination of death (DNDD) and the success of organ donation.
• To determine if organ dysfunction in DNDD predicts graft success post-transplantation.

Main Methods:

• Retrospective analysis of 105 organ donors, reviewing clinical data 12 hours before and after NDD declaration.
• Calculation of organ-specific Sequential Organ Failure Assessment (SOFA) scores to quantify organ dysfunction.
• Comparison of organ dysfunction levels between DNDD donors and non-donors (organs not transplanted).

Main Results:

• Severe organ dysfunction (SOFA 3 or 4) was observed in 96% of cardiac, 27.5% of lung, and 3.3% of liver donors.
• No significant difference in organ dysfunction between donors and non-donors, except for lung donors (lower P/F ratio in non-donors, p=0.02).
• Graft failure rates were low (0.74% kidney, 11.4% pancreas), with no significant difference in donor glucose levels between functioning and failed pancreas recipients.

Conclusions:

• Current measures of organ failure and dysfunction do not reliably predict organ donation success.
• Successful donor management, even with severe organ dysfunction, can lead to successful organ transplantation and save lives.
