Ischemic Preconditioning of Liver in Cadaver Donors
Ischemic Preconditioning · Not specified
About this trial
The long-term goals of this proposal are to develop clinical protocols of donor preconditioning to improve liver graft function and ameliorate complications of poor graft function after liver transplantation. Achievement of these objectives would improve liver recipient outcomes, increase utilization of livers and alleviate the current critical shortage of livers for transplantation. More stringent liver donor selection intended to decrease the complications of poor graft function conflicts directly with efforts to maximize the use of donor livers. Ischemic preconditioning (IPC) of liver attenuates hepatic ischemia reperfusion injury (IRI) in animals. Preliminary data show hepatic IPC effectively decreases IRI following hepatic resection in humans. The specific aims of this project are: AIM 1: To test the hypothesis that 10 minutes of hepatic ischemic preconditioning in deceased donors would improve liver graft function and decrease injury in the early post transplant period. AIM 2: To test the hypothesis that ischemic preconditioning of deceased donor livers would decrease systemic inflammatory response in liver recipients in the early post transplant period. AIM 3: To examine whether ischemic preconditioning of deceased donor livers decreases early post transplant pulmonary edema and acute rejection and shortens hospital stay.
