Randomized Controlled TrialDoes using the bispectral index (BIS) during craniotomy affect the quality of recovery?
One of the aims of neuroanesthesia is to provide early postoperative recovery and neurologic examination in patients undergoing supratentorial surgery. Our aim was to investigate the role of using the bispectral index (BIS) in recovery from anesthesia and altering drug administration in patients undergoing craniotomy. Fifty American Society of Anesthesiologists' (ASA) physical status I-II patients undergoing craniotomy were included in the study. ⋯ Times to first spontaneous breathing, eye opening, and extubation (P = 0.035, P = 0.001, and P = 0.0001, respectively) were significantly shorter in the BIS-guided group. Time to an Aldrete score of 9-10 and adequate neurologic assessment were similar between the groups. In conclusion, BIS monitoring by supratentorial craniotomy under general anesthesia reduced the maintenance anesthetic concentration and narcotic drug usage and lowered the recovery times from general anesthesia.
