[Narcotrend index monitoring can predict the recovery of consciousness in patients undergoing abdominal surgery].

Objective: To investigate the value of Narcotrend (NT) index monitoring versus standard hemodynamic parameters in predicting the recovery of consciousness in patients undergoing abdominal surgery.

Methods: Forty ASA I or II patients undergoing elective abdominal surgery were randomized into two groups to receive sevoflurane-sufentanil anesthesia monitored by NT index or solely by clinical parameters. Anesthesia was induced with the inhalation of 8% sevoflurane and sufentanil target-controlled infusion at 0.
