Brief Summary:
We investigated the efficacy and the safety of the pharmacokinetic model-based patient-controlled analgesia (PCA) regimens of fentanyl for postoperative analgesia after total intravenous anesthesia (TIVA).

Condition or disease Intervention/treatment Phase
Analgesia Disorder Other: FX2-2-2 Other: D6-4-2 Other: D8-4-2 Not Applicable

Detailed Description:
Infusions of fentanyl (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr, or at the decremental rates of 6.0 ml/hr or 8.0 ml/hr during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively.

Arm Intervention/treatment
Experimental: FX2-2-2
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr
Other: D6-4-2
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0 ml/hr (D6-4-2) and 8.0 ml/hr (D8-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively. The visual analogue scores (VAS), the incidence of inadequate analgesia, the frequency of intervention of PCA, and side effects were evaluated.
Other Name: decremantl PCA 6-4-2

Other: D8-4-2
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0 ml/hr (D6-4-2) and 8.0 ml/hr (D8-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively. The visual analogue scores (VAS), the incidence of inadequate analgesia, the frequency of intervention of PCA, and side effects were evaluated.
Other Name: decremental PCA 8-4-2

Active Comparator: D6-4-2
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the decremental rates of 6.0 ml/hr (D6-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr,

Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0 ml/hr (D6-4-2) and 8.0 ml/hr (D8-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively. The visual analogue scores (VAS), the incidence of inadequate analgesia, the frequency of intervention of PCA, and side effects were evaluated.

Primary Outcome Measures :
  1. visual analogue scores (VAS) [ Time Frame: until post-operative 24 hrs ]
    The assessments of analgesia and patient condition were performed at the time points of immediate post-operative periods (1, 15, 30, 45, and 60 min) and post-operative 2, 3, 4, 6, 12 and 24 hr.
