Propofol and etomidate are effective for ambulatory cardioversion, with propofol leading to faster early recovery and improved psychomotor function. Both agents ensure hemodynamic stability, allowing for safe discharge 30 minutes post-procedure.

Area of Science:

  • Anesthesiology
  • Cardiology
  • Pharmacology

Background:

  • Ambulatory cardioversion requires safe and effective anesthetic agents for induction and recovery.
  • Propofol and etomidate are commonly used induction agents, but their comparative effects on recovery from cardioversion are not fully elucidated.

Purpose of the Study:

  • To compare the effects of propofol and etomidate on recovery after ambulatory electrical cardioversion.
  • To assess hemodynamic stability and psychomotor recovery following induction with either propofol or etomidate.

Main Methods:

  • A prospective, randomized, blinded, comparative study involving 25 patients undergoing repetitive electrical cardioversion.
  • Patients received either propofol (1 mg/kg) or etomidate (0.2 mg/kg) for cardioversion, with crossover to the other agent in a subsequent session if needed.

  • Hemodynamic parameters, time to recovery milestones, and postanesthetic recovery scores (Aldrete, Steward) were recorded.

    • Main Results:

    • Hemodynamic parameters (blood pressure) and cardioversion success rates were similar between propofol and etomidate groups.
    • Patients induced with propofol demonstrated significantly faster awakening, improved psychomotor performance at 10 and 15 minutes, and higher recovery scores.
    • No significant differences in recovery were observed at 20 minutes post-cardioversion.

    Conclusions:

    • Both etomidate and propofol are suitable for ambulatory cardioversion, maintaining hemodynamic stability.
    • Propofol offers advantages in terms of faster early recovery and psychomotor function compared to etomidate.
    • Patients can be safely discharged from recovery areas approximately 30 minutes after cardioversion.
