The aim of this study was to evaluate the effects of intraperitoneal and extraperitoneal CO2 insufflation on blood gases and respiratocy mechanics in laparoscopic surgery. Seventy patients, classified as ASA I or II, within normal limits of height and weight, between ages 19-77, who underwent elective intraperitoneally performed laparoscopic cholecystectomy (group K, n=35) or extraperitoneally performed laparoscopic inguinal hernia repair (group H, n=35) were included in the study. All patients received standard general anesthesia with standard mechanical ventilation parameters. Intraabdominal pressure was kept under 12 mmHg throughout the operation. Arterial blood gases were analyzed; before induction (A), 10 minutes after induction at horizontal position (B), 10 minutes after insufflation at horizontal position (C), 20 minutes after insufflation at 15° head-down position (D), 30 minutes after insufflation at 15° head-up position (E) and, after desufflation at horizontal position (F). Dynamic lung compliance (Cdyn) was monitorised after the onset of mechanical ventilation. Except the F period, there was no significant difference between two groups' PaCO2 values (p>0.05). The PaCO2 values of group H were found significantly high in the F period, compared to the C period (p
