Primary Outcome Measures
NameTimeMethod
the first postoperative 24 h (patient controlled analgesia [PCA])morphine consumptionthe first postoperative 24 hour

the cumulative patient controlled analgesia morphine consumption required by the patients to relieve their pain in the first postoperative 24 h

Secondary Outcome Measures
NameTimeMethod
The level of consciousness assessed by "the Modified Ramsay Sedation score"the score will be measured at 8 hour, 16 hour and 24 hour postoperatively

awake levels were: I = anxious, agitated, or restless; II = cooperative, oriented, and tranquil; III = responds to command, and asleep levels were dependent on patient's response to a light glabellar tap or loud auditory stimulus; IV= brisk response; V = a sluggish response; and VI = no response)

The occurrence of vomitingThe outcome will be obtained once 24 hour postoperatively

vomiting is forceful discharge of stomach contents

The intensity of pain measured by visual analogue pain scale (VAS)The outcome will be assessed at 0 hour, 2 hour, 4 hour,8 hour, 16 hour and 24 hour postoperatively.

The intensity of pain measured by visual analogue pain scale (VAS) in which 0 = no pain and 10 = the maximum imaginable pain

The quality of postoperative recovery, assessed by "The QoR-40 questionnaire" (the quality of recovery-40 questionnaire)the questionnair will be assessed once, 24 hour postoperatively

It measures five components of patient recovery: physical comfort (12 questions), physical independence (5 questions), emotional state (9 questions), psychological support (7 questions), and pain (7 questions). The sum of each component generates an aggregate score that ranges from 40 (i.e., extremely poor quality of recovery) to 200 (i.e., excellent quality of recovery)
