Primary Outcome Measures:
  • Anesthetic effectiveness (presence/absence of body movement, presence/absence of awakening, presence/absence of need for rescue medication, control of BP/heart rate, presence/absence of intraoperative recall) [ Time Frame: anesthesia maintenance ] [ Designated as safety issue: No ]
  • Time to extubation [ Time Frame: end of anesthesia ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Times to awakening, stating birth date, reaching Aldrete score of 8 [ Time Frame: end of anesthesia ] [ Designated as safety issue: No ]
  • Changes in BIS [ Time Frame: anesthesia maintenance ] [ Designated as safety issue: No ]
  • Need for rescue treatment [ Time Frame: anesthesia maintenance ] [ Designated as safety issue: No ]
  • Changes in end-tidal and inspired concentrations [ Time Frame: anesthesia maintenance ] [ Designated as safety issue: No ]
  • desflurane (BLM-240) concentrations that maintain anesthesia and patient stability without rescue medication for blood pressure or anesthesia [ Time Frame: anesthesia maintenance ] [ Designated as safety issue: No ]

Detailed Description:

The study evaluates the efficacy and safety of the use of desflurane (BLM-240) (with and without nitrous oxide) in maintenance of general anesthesia in adult patients undergoing surgical procedures typically performed under general anesthesia in Japan (thoracic, abdominal, joints, back, and neck), where analgesics and muscle relaxants are concomitantly used. The study is also intended to demonstrate the non-inferiority of desflurane with nitrous oxide to sevoflurane with nitrous oxide in time to awakening/recovery.
