Pro-Con Debate: Should All General Anesthesia Be Done Using Target-Controlled Propofol Infusion Guided by Objective...

Area of Science:

• Anesthesiology
• Pharmacology
• Patient Safety

Background:

• A long-standing debate exists regarding the optimal general anesthesia technique.
• Target-controlled infusion (TCI) propofol anesthesia is contrasted with volatile anesthetic techniques.
• This debate highlights scientific, cultural, and geographical divides within the anesthesia community.

Purpose of the Study:

• To critically evaluate the pros and cons of target-controlled propofol anesthesia versus volatile anesthetics.
• To inform anesthetic technique selection based on patient needs and specific clinical contexts.
• To consider patient outcomes, drug availability, and environmental impact.

Main Methods:

• Pro-con commentary based on existing scientific literature.
• Analysis of pharmacokinetic-pharmacodynamic principles for TCI propofol.
• Evaluation of depth of anesthesia monitoring (e.g., bispectral index) alongside clinical parameters.
• Consideration of volatile anesthetic properties and administration routes.

Main Results:

• Pro-TCI propofol: less postoperative nausea, higher patient satisfaction, better titration via pharmacokinetic models, and objective depth monitoring.
• Con-TCI propofol: volatile anesthetics may be preferred for procedures with ischemia/reperfusion or severe inflammation.
• Volatile anesthetics offer advantages during drug shortages and when IV access is difficult.
• Both anesthetic types pose environmental concerns.

Conclusions:

• Anesthetic choice requires careful consideration of individual patient factors, clinical environment, and available evidence.
• Tailoring anesthesia to patient needs involves weighing drug behavior, outcomes, economic, and environmental factors.
• A balanced, evidence-based approach is recommended for selecting between TCI propofol and volatile anesthetics.
