Spots Global Cancer Trial Database for Remote Ischemic Conditioning (RIC) in Recipients of Brain Death Donor Livers - A Feasibility and Safety Study

Study Description

Brief Summary: This study will assess the feasibility of lower limb-ischemia induced Remote Ischemic Conditioning (RIC) in the perioperative period before, during, and after Orthotopic Liver Transplantation (OLT). Remote ischemic conditioning will consist of 3 cycles of 5 minutes of lower limb ischemia induced via a mid-thigh pneumatic tourniquet, followed by 5 minutes of reperfusion. Interventions will take place after anesthesia induction but before surgery, at the completion of the procedure, and on the mornings of post-operative days 1-4.

Detailed Description: Orthotopic liver transplantation (OLT) is associated with a very high risk of complications. In a recent multi-center study of 450 patients, 79% had at least one complication and 63% had severe (Clavien-Dindo grade III or higher) complications. The number and severity of complications are associated with death within 30 days, hospital length of stay, graft and patient survival. Infections are the most common group of complications, followed by pulmonary, renal and liver graft dysfunction. Interventions that decrease these complications after OLT are likely to improve clinical outcomes. Remote ischemic conditioning is an innate biological phenomenon wherein a brief single or repetitive ischemic stimulus in an organ or tissue such as skeletal muscle induce protection in remote/distant organs against ischemia and other noxious stimuli. This effect can be induced by inflating a pneumatic tourniquet on a leg or arm for a few minutes (usually 5-10) and subsequently deflating to allow reperfusion. This process is usually repeated 3-4 times to ensure an adequate dose of the conditioning stimulus. The conditioning stimulus could be applied before (Preconditioning), concurrent with (Perconditioning), or soon after the index noxious/ischemic insult (Postconditioning). The goal of this study is to assess the feasibility, patient acceptance, and safety of RIC in liver recipients. In addition, the investigators will obtain data on posttransplant complications. Information obtained from this study will help guide the design of a future randomized, controlled trial to test the benefit of RIC in liver recipients.
