Donors with cardiac arrest: Improved organ recovery but no preconditioning benefit in liver allografts
Historically, organ recovery rates in donors with cardiac arrest (CA) have been low, presumably from hemodynamic instability. We hypothesized that donor resuscitation has improved hemodynamic stability and organ recovery in CA donors, and that CA triggers ischemic preconditioning (IP) in liver graft...

Zusammenfassung: | Historically, organ recovery rates in donors with cardiac arrest (CA) have been low, presumably from hemodynamic instability. We hypothesized that donor resuscitation has improved hemodynamic stability and organ recovery in CA donors, and that CA triggers ischemic preconditioning (IP) in liver grafts.
A total of 131 donor pairs with and without CA were matched in age, gender, and year of recovery. Hemodynamic stability was determined by vasopressor use. Abdominal and thoracic organs recovered and livers transplanted were compared between the groups. Liver graft function, injury, and IP benefit were examined by comparing liver chemistries after transplantation and postperfusion biopsies between recipients of grafts from both groups (n=40 each).
Hemodynamic stability was similar in both groups, but recovery of thoracic organs was significantly lower in CA versus non-CA donors (35 vs. 53%, P |
