Intraoperative Management of High-Risk Liver Transplant Recipients: Concerns and Challenges

Abstract

Liver transplantation (LT) offers patients with liver disease a real chance for long-term survival. In the past decade, successful survival after LT along with the Model for End-Stage Liver Disease-based allocation policy have increased willingness to accept patients with a higher risk profile and marginal organs and to prioritize the sickest patients on the waiting list. Therefore, the anesthesiologist now deals with very challenging patients. In the present review, we aimed to highlight key aspects of intraoperative LT management in high-risk patients and to place these aspects in the perspective of their impact on perioperative outcomes. Conservative standardized perioperative strategies mandate a switch toward accurate and tailored perioperative anesthetic care to maintain the steady improvement in recipient survival rates after LT. In our opinion, continuous assessment of fluid status and cardiac performance, strategies promoting graft decongestion, rational hemostatic management, and the identification of LT recipients with potential risk of vascular complications should constitute the cornerstone of intraoperative management.
