#Trendelenburg position registration#
Trial registration The trial was registered prior to patient enrollment at (NCT04224532, Date of the registration: January 8, 2020) The present study demonstrates that applying the reverse Trendelenburg position before pneumoperitoneum prevented an increase in the ONSD in patients undergoing laparoscopic cholecystectomy. The number of patients with nausea was higher in group S (p = 0.027). In group S, Ppeak was higher and Cdyn was lower at T2 (p < 0.001). The mean arterial pressure was lower in group RT at T2, and the HR was not different between the groups (p < 0.001). The rSO2 and SpO2 were not different between the groups. In the same group, the number of patients with an ONSD above 5.8 mm was higher at T2, T3, and T4 (p < 0.001, p = 0.042, p = 0.036, respectively). Background and perioperative characteristics were similar in both groups. The end-tidal carbon dioxide (EtCO 2), regional cerebral oxygen saturation (rSO 2), peripheral oxygen saturation (SpO 2), mean arterial pressure (MAP), heart rate (HR), peak inspiratory pressure (Ppeak), and dynamic compliance (Cdyn) were recorded. The ONSD was measured at the following time points: T0: before anesthesia T1: after endotracheal intubation T2: after pneumoperitoneum in group S and after positioning in group RT T3: after positioning in group S and after pneumoperitoneum in group RT T4: 30 min after endotracheal intubation, and T5: after desufflation. Seventy-nine patients were allocated to two groups according to whether pneumoperitoneum was applied in the supine position (group S, n = 40) or in the reverse Trendelenburg position (group RT, n = 39). The aim of this randomized controlled trial was to determine whether applying the reverse Trendelenburg position before pneumoperitoneum has a preventive effect on increased intracranial pressure using optic nerve sheath diameter (ONSD) measurement as a noninvasive parameter.
