Effect Inhaled Nitric Oxide in Adult Liver Transplant

Summary

Liver transplantation remains the only cure for patients with end-stage liver disease. Despite continuous advances in medical care, ischemia-reperfusion injury (IRI) (tissue damage that occurs when blood supply is restored to an area that has been deprived of oxygen) remains a major contributor to complications with the newly transplanted liver. IRI can lead to a condition known as post-reperfusion syndrome that involves profound narrowing of blood vessels, significantly low blood pressure, and an increased requirement of medication to control blood pressure. In some cases, post-reperfusion syndrome can progress to a condition known as post-reperfusion vasoplegia which is a condition where severely low blood pressure persists even after blood flow is restored to the liver. This is often accompanied by complications such as improperly functioning kidneys, blood clotting disorders, and complications with the transplanted liver that can significantly affect patient outcomes. Recent studies have shown than inhaled nitric oxide (a gas that can relax blood vessels) can reduce the severity of IRI in the liver. This study is being conducted to determine whether the administration of inhaled nitric oxide during surgery reduces the severity of post-reperfusion syndrome and the incidence of post-reperfusion vasoplegia in adult patients undergoing liver transplantation. This is a before-and-after study design that will involve both the retrospective collection of data between the time period of January 1, 2020 - May 31, 2025 and prospective interventions involving adult liver transplant recipients.
