"Comparison of of Volume-Controlled Ventilation and Pressure-Controlled Ventilation Modes in Laparoscopic Cholecystectomy"

This randomized controlled trial compares volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) in adult patients undergoing elective laparoscopic cholecystectomy under general anesthesia. The study evaluates the effects of both ventilation modes on static lung compliance and end-tidal carbon dioxide (EtCO₂) at predefined intraoperative time points. The objective is to determine whether pressure-controlled ventilation provides improved respiratory mechanics and more effective ventilation compared with volume-controlled ventilation during laparoscopic surgery.
