    Objective: Today, the popularity of laparoscopic techniques is increasing steadily with many advantages. However, laparoscopic techniques can have many negative effects on respiratory and hemodynamic systems. In this study, we aimed to evaluate the effect of CO2 insufflation applied at different pressures on hemodynamic parameters with non-invasive cardiac output monitor in patients planning elective laparoscopic cholecystectomy. Material and Method: 40 patients undergoing elective laparoscopic cholecystectomy between 18 and 60 years of age with ASA 1-2 were included in the study. Pneumoperitoneum was formed in Group I at 14 mmHg pressure and in Group II at 10 mmHg pressure. Before induction (basal), after intubation, 15 minutes after insufficiency and 15 minutes after desuperation; CO (Cardiac output), CI (Cardiac index), SV (Stroke Volume), SVI (Stroke Volume Index) measurements were taken and evaluated with USCOM. Results: There was no difference between the demographic data betwen the groups. Significantly decreased values of CO, CI and SVI were observed in both groups. Conclusion: CO2-induced pneumoperitoneum causes a significant decrease in cardiac function as well as respiratory functions. The USCOM method is a simple, effective and safe method of detecting these changes. Increasing the applied pressure also increases the severity of the changes.
