Laparoscopic cholecystectomy significantly impacts haemodynamic parameters, reducing cardiac index (CI) and ejection fraction (EF). These changes, particularly a persistent drop in EF, suggest potential circulatory complications in patients with compromised cardiovascular health.

Area of Science:

  • Cardiovascular Physiology
  • Surgical Anesthesia

Context:

  • Laparoscopic cholecystectomy is a common surgical procedure.
  • Understanding haemodynamic changes during this procedure is crucial for patient safety.

Purpose:

  • To investigate the haemodynamic effects of laparoscopic cholecystectomy.
  • To assess changes in cardiac index (CI), stroke index (SI), heart rate (HR), mean arterial pressure (MAP), systemic vascular resistance index (SVRI), ejection fraction (EF), and limb இரத்த ஓட்டக் குறியீடு (LCWI).

Summary:

  • Haemodynamic parameters were monitored in 24 patients undergoing elective laparoscopic cholecystectomy using transthoracic electric bioimpedance.
  • CO2 insufflation led to significant decreases in CI, HR, EF, and LCWI, with a notable rise in SVRI.
  • Further reductions in CI and SI were observed 30 minutes post-insufflation, with EF remaining significantly reduced. Post-desufflation, most parameters normalized except for EF, which remained at the lower physiological limit.

Impact:

  • The study highlights potential risks of circulatory complications in patients with pre-existing cardiovascular conditions undergoing laparoscopic cholecystectomy.
  • Findings suggest careful consideration is needed when indicating this procedure for patients with compromised cardiovascular health.
