Liver protection in the perioperative setting

Area of Science:

• Anesthesiology
• Hepatology
• Surgical Medicine

Background:

• Increasing number of surgeries performed on patients with pre-existing liver impairment.
• Societal expectations driving advances in surgical and anesthetic management.
• Need to address high risk of perioperative liver failure in this population.

Purpose of the Study:

• Outline pathophysiological alterations in patients with liver impairment.
• Highlight anesthetic challenges in minimizing perioperative liver insults.
• Review strategies for intraoperative management and recent clinical trials.

Main Methods:

• Review of pathophysiological alterations in liver impairment.
• Analysis of anesthetic challenges and strategies.
• Discussion of pharmacological and ischemic preconditioning.
• Summary of recent clinical trial results.

Main Results:

• Identified key pathophysiological alterations relevant to anesthesia.
• Highlighted the critical balance between reducing blood loss and maintaining liver perfusion.
• Detailed the effects of various anesthetic agents on hepatic function, perfusion, and toxicity.
• Summarized advances in preconditioning techniques and clinical trial outcomes.

Conclusions:

• Anesthetic management requires careful consideration of liver function and perfusion.
• Minimizing intraoperative insults is crucial for patients with liver impairment.
• Advances in preconditioning offer potential protective strategies.
• Further research and clinical trials are essential to optimize outcomes.
