2. Fig 1
Characteristics for SPI (a), BIS (b), and end-tidal sevoflurane concentration (c) representing major time points during anaesthesia in the SPI (blue) and control (green) groups. Values are mean (sd). Baseline, before induction of anaesthesia; LOC, loss of consciousness; pre-intubation, before intubation; max intubation, maximum value during/after intubation; pre-incision, before start of surgery by incision; max incision, maximum value during/after incision (I); suture, final suture; E, extubation. ±values are in minutes.
