OBJECTIVE: The aim of the study was to compare intraoperative changes on the haemodynamics in the head-up and head-down position in laparoscopic cholecystectomy and gynaecologic surgery. MATERIAL-METHODS: The study was conducted on 40 ASA I-II patients aged 18-55 years prospectively and in a blind manner, by dividing equally into two groups for the head-down (Group HD, n=20)and head-up position (Group HU, n=20) during the laparoscopic adnexial surgery and laparoscopic cholecystectomy. The anaesthesia was induced with propofol and maintained with sevoflurane. For muscle relaxation during TI, vecuronium was given to all participants. The heart rate (HR), systolic, diastolic, mean arterial pressure (SAP; DAP; MAP), peripheral O2 saturation (SpO2) and end tidal corbondioxide (ETCO2) were assessed before anaesthesia induction and during the surgery. The Wilcoxon and Mann-Whitney U test were used as indicated. RESULTS: SAP increased at 10th, 20th, 30th min, DAP increased at 20th, 30th min and MAP increased only at 20th min in Group HD compared to Group HU (p CONCLUSION: We concluded that in healthy adults, the effects of head-up or head-down position during laparoscopic surgery with 10-12 mmHg pressure of CO2 pneumoperitoneum did not deteriorate in haemodynamics.
