Effects of pneumoperitoneum and patient position on intracranial pressure in obese patients undergoing laparoscopic cholecystectomy

Background/Aim: Optic nerve sheath diameter (ONSD) measurement is one of the non-invasive techniques used for intracranial pressure (ICP) measurement. ICP changes have been evaluated based on ONSD measurements during many laparoscopic surgeries. However, such analyses in obese patient populations are limited. This study aimed at investigating effects pneumoperitoneum and reverse Trendelenburg head-up position patients undergoing cholecystectomy. Methods: observational included 60 female who were scheduled Obese with a body mass index (BMI) 30 above assigned to Group 1, while BMI < 2. The first was performed just before insufflation (T1). second taken 5 min after (T2), third placing (T3), last deflation maintained (T4). Results: T2 T3 time points 1 higher than 2 (P = 0.012 versus P 0.020). Both values patients. In patients, significantly T1 T4 (T2 > T1; 0.001, T4; 0.001). No significant difference between found. T1, T3, measurements, T3; 0.022, 0.048). noted. Conclusion: Laparoscopic cholecystectomy does not cause an increase limited pressure, position, controlled anesthesia.
