Deep anaesthesia reduces postoperative analgesic requirements after major urological procedures.

Background And Objective: There is evidence from previous studies that deeper anaesthetic levels reduce postoperative pain along with analgesic requirements. The aim of this study was to confirm this observation during major urological procedures under sevoflurane anaesthesia.

Methods: Seventy ASA I or II patients undergoing radical prostatectomy or nephrectomy were randomly allocated into two groups: the L-BIS group with BIS (bispectral index scale) values kept within a range of 20-30 and the H-BIS group with values within the range of 50-60.
