结局指标
主要结局
First time to analgesic requirement
时间窗: 1st 24 hour postoperatively
After extubation, an intravenous patient - controlled system, will be connected to the patient (Accufuser plus 100 ml) will be prepared with 60 ml isotonic saline containing 60 mg morphine , it will be programmed to give 0.5 ml bolus dose with lockout interval of 8 minutes. Time to first bolus will be recorded considering extubation time is the zero time
