General anesthesia during atrial fibrillation ablation: Standardized protocol and experience

Area of Science:

• Cardiology
• Anesthesiology
• Medical Devices

Background:

• General anesthesia (GA) is standard for atrial fibrillation (AF) ablation, but optimal protocols remain undefined.
• Anesthesia protocols impact ablation outcomes and operating room efficiency.
• A high-volume center developed a specific GA protocol for AF ablation.

Purpose of the Study:

• To report a general anesthesia (GA) protocol for atrial fibrillation (AF) ablation.
• To optimize mapping and ablation conditions for efficiency.
• To evaluate the safety and efficacy of the protocol regarding recovery and laboratory utilization.

Main Methods:

• Propofol as the sole anesthetic agent with Fentanyl for analgesia.
• Minimized intravenous fluid administration.
• Ventilation modulation and specific drug administration (rocuronium, isoproterenol, furosemide) timed for optimal procedure and recovery.

Main Results:

• 1286 patients underwent AF ablation using the protocol (2017-2018).
• Median extubation time was 9 minutes post-procedure.
• Low complication rate (1 reintubation for heart failure), with minimal fluid administration (370 mL).

Conclusions:

• The developed GA protocol is safe and effective for AF ablation.
• The protocol facilitates efficient patient recovery and rapid extubation.
• It enhances laboratory utilization without compromising patient safety.
