Summary

Sevoflurane anesthesia maintained better hemodynamic stability than propofol during laparotomic cholecystectomy. Stroke volume was significantly higher with sevoflurane, indicating improved myocardial contractility.

Area of Science:

  • Anesthesiology
  • Cardiovascular Physiology
  • Surgical Anesthesia

Background:

  • Myocardial contractility is crucial during surgery.
  • Comparing anesthetic agents' effects on cardiac function is important for patient safety.
  • Laparotomic cholecystectomy requires careful hemodynamic management.

Purpose of the Study:

  • To compare the effects of sevoflurane and propofol anesthesia on myocardial contractility.
  • To evaluate hemodynamic stability during laparotomic cholecystectomy under different anesthetic regimens.
  • To assess parameters like heart rate, cardiac index, and stroke volume.

Main Methods:

  • Randomized controlled trial with 40 patients undergoing laparotomic cholecystectomy.
  • Patients were assigned to either sevoflurane or propofol anesthesia.

  • Transesophageal echo-Doppler was used to measure heart rate, cardiac index, stroke volume, left ventricular ejection time, and acceleration.

    • Main Results:

    • All measured hemodynamic parameters decreased significantly after anesthesia induction and incision (p < 0.05).
    • Stroke volume showed a significantly higher value in the sevoflurane group compared to the propofol group (p < 0.05).
    • Sevoflurane group: stroke volume decreased from 66 to 63 ml/beat; Propofol group: stroke volume decreased from 64 to 58 ml/beat.

    Conclusions:

    • Sevoflurane anesthesia provides better hemodynamic stability compared to propofol during laparotomic cholecystectomy.
    • Sevoflurane may be a preferred anesthetic agent for maintaining myocardial contractility in this surgical setting.
    • These findings support the use of sevoflurane for improved cardiac function during abdominal surgery.
