Electroencephalogram Predicts Post-operative Delirium
Trial Parameters
Brief Summary
The goal of this observational study is to investigate the predictive value of sub-hairline electroencephalography (EEG) during anesthesia recovery for postoperative delirium (POD). The main question to be answered is: * Can sub-hairline EEG measured during anesthesia recovery serve as a reliable predictor of POD? Adult patients undergoing elective craniotomy and admitted to the ICU will be enrolled. Sub-hairline EEG will be monitored until ICU discharge.
