Laparoscopic cholecystectomy with combined anesthesia can cause sudden circulatory collapse due to vagal reflex. Careful anesthetic management, including preventing parasympathetic dominance, is crucial for patient safety.

Area of Science:

  • Anesthesiology
  • Surgical Anesthesia

Background:

  • Laparoscopic cholecystectomy is a common surgical procedure.
  • Combined general and epidural anesthesia is utilized for pain management during the surgery.

Observation:

  • A 52-year-old female experienced sudden bradycardia and hypotension during intraabdominal insufflation in reverse-Trendelenburg position.
  • Hemodynamic instability resolved upon releasing insufflation pressure and administering ephedrine and Hespander.
  • A second careful insufflation did not precipitate similar circulatory collapse.

Findings:

  • The circulatory collapse was likely induced by a vagal reflex.
  • Reduced cardiac preload from the reverse-Trendelenburg position and epidural anesthesia may have contributed to or exacerbated the event.
  • The vagal reflex was mitigated by careful anesthetic management.

Implications:

  • Prophylactic measures and prevention of parasympathetic overactivity are vital in combined anesthesia for laparoscopic cholecystectomy.
  • Anesthesiologists should be vigilant for vagal reflex-induced hemodynamic instability during laparoscopic procedures.
  • This case highlights the importance of understanding combined anesthetic effects on cardiovascular stability.
