Anaesthesia for elective liver resection: some points should be revisited

Area of Science:

• Anesthesiology
• Hepatobiliary Surgery

Background:

• Surgical advancements have simplified anesthetic care for elective liver resections.
• Pre-existing liver disease necessitates specific preoperative assessments.

Purpose of the Study:

• To outline current anesthetic management strategies for elective liver resection.
• To identify key considerations for patients with and without parenchymal liver disease.

Main Methods:

• Review of anesthetic management principles for liver resection.
• Discussion of intraoperative techniques and monitoring.
• Analysis of perioperative fluid management and transfusion strategies.

Main Results:

• Intermittent portal triad clamping is preferred over prolonged ischemia.
• Intraoperative antibiotic prophylaxis is recommended.
• Systematic invasive hemodynamic monitoring is often unnecessary; arterial cannulation is reserved for specific high-risk scenarios.
• A significant proportion of patients do not require blood transfusions.
• Postoperative ascites is common and not prevented by fluid restriction.

Conclusions:

• Anesthetic management type does not significantly impact outcomes.
• Early intervention with volume expansion, diuretics, and vasopressors is crucial for preventing kidney failure post-liver resection.
• Careful patient assessment and tailored anesthetic approaches optimize outcomes in liver surgery.
