Comparison of the effects of head-down and head-up position on intraocular pressure and haemodynamics during laparoscopic abdominal surgery

Abstract

The aim of our study was to compare intraoperative changes on the haemodynamics and intraocular pressure in the head-up and head-down position in laparoscopic cholecystectomy and gynaecologic surgery. This cohort study (prospective observational study) was made in Antalya Education and Research Hospital (Turkey) between 2015 and 2017. Seventy seven patients undergoing laparoscopic cholecystectomy (head-up position, n=42 ) and laparoscopic gynecology operations (head-down position=35) were included. The intraocular pressure (IOP) was measured for both eyes at defined intervals during the procedure with Schiotz tonometer. During of surgery, heart rate, mean arterial blood pressure, sistolic arterial blood pressure, diastolic arterial blood pressure and ETCO2 were also recorded. IOP was detected to be higher in Group II at the 5th minute of CO2 insufflation (17.17±2.91) and at the 5th minute of head-down position (17.97±2.83), P
