Outcomes
Primary outcome [1] 1826 0
Incidence of dreaming during anaesthesia as evidence by self-report
Timepoint [1] 1826 0
At an immediate postoperative interview
Secondary outcome [1] 3200 0
Times to eye open
Timepoint [1] 3200 0
After cessation of anaesthetic administration, patients may first spontaneously open their eyes while they are still on the operating theatre or may not open their eyes until they are in the recovery room. Whenever the patient first opens their eyes, this will be recorded. This endpoint only happens once.
Secondary outcome [2] 3201 0
Orientation and recovery room discharge
Timepoint [2] 3201 0
Every 2 min after the patient opens their eyes they are assessed for orientation to time place and person. This endpoint will be recorded once only, on the first occasion that the patient is orientated. The time of recovery room discharge will be recorded once, when the patient leaves the recovery room.
Secondary outcome [3] 3202 0
EEG variables during maintenance of anaesthesia and during recovery.
Timepoint [3] 3202 0
Continuously during maintenance and recovery (data points every 1 min)

Summary
Brief summary
Dreaming is commonly reported after anaesthesia. There is some evidence that dreaming is more likely to be reported after anaesthesia maintained with propofol than anaesthesia maintained with desflurane. In this study, we will randomise patients having non-cardiac surgery to anaesthesia with propofol or desflurane and will measure the incidence of dreaming. Post-operative observers will be blind to group allocation (propofol or desflurane)
