Processed EEG for Monitoring of Anesthetic Depth in Intracranial Tumor Surgery

An important feature of neurosurgical anesthesia is early postoperative recovery of consciousness with minimal residual sedation. This is a key factor to enable early neurological assessment and early discovery of postoperative complications. The goal of this single centre clinical trial is to compare propofol/remifentanil anesthesia delivered by manual total intravenous anesthesia (mTIVA) or target controlled infusion (TCI) for intracranial tumor resection via craniotomy. Anesthetic depth will be assessed by a simplified processed EEG (pEEG). The main question is time spent within recommended pEEG- levels from anesthesia induction until end of surgery. Secondary questions are: * mean pEEG-level, time from end of surgery to consiousness, * peroperative propofol/remifentanil consumption * postoperative degree of sleepiness * awareness assessment Participants are adults having have planned surgery for open resection of a brain tumor and will receive general anesthesia with propofol and remifentanil randomized to mTIVA or TCI. pEEG vill be blinded. * Participants will be asked to grade postoperative sleepiness using a specific scale * Follow up regarding awareness will be performed.
