Anesthesia approach to hepatic transplantation.

Area of Science:

• Anesthesiology
• Transplantation Surgery
• Hepatology

Background:

• Orthotopic liver transplantation (OLT) presents significant anesthetic challenges.
• Patients often have multiple comorbidities affecting cardiovascular, respiratory, and hematologic systems.
• Intraoperative hemodynamic, metabolic, and coagulation status can change rapidly.

Purpose of the Study:

• To outline key considerations for anesthesia management in OLT.
• To highlight the importance of preoperative assessment and intraoperative monitoring.
• To present findings from the initial 100 liver transplantations at the institution.

Main Methods:

• Comprehensive preoperative evaluation of cardiovascular, respiratory, and hematologic systems.
• Utilization of isoflurane as the primary anesthetic agent to minimize hepatotoxicity.
• Continuous hemodynamic monitoring and immediate laboratory analysis intraoperatively.
• Implementation of a rapid infusion pump and venovenous bypass.

Main Results:

• Isoflurane demonstrated minimal liver toxicity.
• The use of a rapid infusion pump and venovenous bypass was associated with normalized hemodynamic and renal function in the initial 100 cases.
• Effective management of intraoperative changes was achieved.

Conclusions:

• Anesthesia for OLT requires meticulous preoperative assessment and vigilant intraoperative management.
• Specific anesthetic agents like isoflurane and supportive technologies such as rapid infusion pumps and venovenous bypass are crucial for successful outcomes.
• These strategies contribute to stabilizing hemodynamic and renal function during liver transplantation.
