About the trial

What the trial wants to find out

The aim of this study is to evaluate the effects of processed electroencephalogram (pEEG) monitoring on recovery and extubation times, length of stay in the post-anesthesia care unit (PACU), postoperative pain, patient comfort, sedation, development of delirium, and length of hospital and intensive care unit stay in laparoscopic surgeries performed in the Trendelenburg (T) or reverse Trendelenburg (RT) positions.

Materials and Methods: This prospective, randomized, single-center study included a total of 136 patients will be scheduled for elective laparoscopic surgery under general anesthesia. Patients will allocated into four groups according to surgical position (Group T or Group RT) and the use of processed electroencephalogram monitoring (Group TBIS and Group RTBIS). Intraoperative depth of anesthesia will be maintained either by titration guided by processed electroencephalogram indices or according to standard clinical parameters. Extubation time, recovery time, length of stay in the PACU, postoperative pain scores, patient comfort, level of sedation, incidence of delirium, and lengths of hospital and intensive care unit stay will be recorded.
