The Effect of Cerebral Oxygenation on Postoperative Recovery in Intracranial Surgery

Patients undergoing intracranial surgery will be divided into two groups; group (Group Control n = 100) and cerebral oxygenation monitoring group (Group Oxygen). all hemodynamic parameters such as systolic blood pressure and diastolic blood pressure, oxygen saturation, Et CO2, SpO2;% and BIS during anesthesia during anesthesia will be recorded intraoperatively and 10 postoperatively in 5 min intervals. After extubation, Modified Aldrete Score, GKS (Glasgow Coma Scale), Ramsey Sedation Scale (RSS), nausea‐vomiting and pain will be recorded in the recovery room. Pain assessment will be done with Visual Analog Scale (VAS). Patient satisfaction will be recorded. MMST (mini mental state test) and ASEM (antisaccadic eye movement test) tests will be performed preoperatively and postoperatively at 1st, 2nd and 3rd days.
