Research progress on strategies of reducing perioperative blood transfusion in liver transplantation

Massive blood loss and blood transfusion constantly occur in liver transplantation. Over the past two decades, the amount of blood transfusion during the perioperative period has been decreased dramatically along with the continual maturity of liver transplantation techniques. The goal of liver transplantation without blood transfusion has been achieved. Since bleeding and blood transfusion are correlated with poor prognosis after liver transplantation, reducing bleeding and unnecessary blood transfusion has become the key objective during perioperative period of liver transplantation. In this article, adverse effects of allogeneic blood transfusion during perioperative period of liver transplantation, coagulation function monitoring of patients with end-stage liver disease, blood transfusion management of liver transplant recipients and the strategies of reducing perioperative blood transfusion in liver transplantation were summarized, aiming to provide reference for reducing the requirement of blood transfusion during perioperative period of liver transplantation.
