Cerebral state index during anaesthetic induction: a comparative study with propofol or nitrous oxide

Background:  Confidently predicting the depth of anaesthesia for the individual patient and independently of drug(s) type using EEG‐based monitors has proven difficult. This open, randomized, explorative study of day surgical patients evaluates the ability of the Cerebral State Monitor™ (Danmeter AB, Odense, Denmark) of anaesthetic depth to identify loss of response (LOR) using either propofol or N20 for induction.
