An interventional study of FX2-2-2 and D6-4-2 in Analgesia Disorder, sponsored by Ajou University School of Medicine. Completed at 1 site in Korea, Republic of. Open to female participants aged 20 Years to 65 Years. Per ClinicalTrials.gov, last updated 2013-02-07.

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).
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.

Exclusion Criteria:
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 · 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 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,
Other: FX2-2-2 · 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 at the decremental rates of 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,
Other: FX2-2-2 · 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.
Also known as: decremental PCA
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.
Also known as: decremantl PCA 6-4-2
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.
Also known as: decremental PCA 8-4-2
visual analogue scores (VAS)
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.
Time frame: until post-operative 24 hrs
