Coagulopathy during liver transplantation.

Area of Science:

• Anesthesiology
• Hepatology
• Transplantation Surgery

Background:

• Hemostasis is a complex defense mechanism involving cellular and humoral coagulation elements, vital for managing vascular damage and hemorrhage.
• Hepatic failure and liver injury can trigger coagulopathy, complicating hemostasis and potentially leading to severe coagulation disorders.
• Liver transplantation presents unique challenges due to inherent hemostatic system alterations and the risk of significant hemorrhage.

Purpose of the Study:

• To review the principles of hemostasis management in liver transplantation.
• To discuss changes in the hemostatic system relevant to liver transplant recipients.
• To outline techniques for reducing hemorrhage during liver transplantation.

Main Methods:

• Review of existing literature on hemostasis, coagulopathy, and liver transplantation.
• Analysis of management strategies including transfusion protocols and coagulation monitoring.
• Evaluation of antifibrinolytic therapy and fluid management techniques.

Main Results:

• Point-of-care testing (POCT) guided transfusion and coagulation management algorithms can decrease blood loss and transfusion requirements.
• Antifibrinolytic therapy has demonstrated efficacy in reducing bleeding during liver transplantation.
• Maintaining low central venous pressure with restrictive fluid administration contributes to minimizing hemorrhage.

Conclusions:

• Optimized hemostasis management protocols are essential for successful liver transplantation.
• The integration of POCT, antifibrinolytic agents, and specific fluid management strategies can significantly improve surgical outcomes.
• Proactive management of coagulopathy and bleeding is critical in liver transplant recipients.
