Study Design
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment
Name: B0 group: bolus 0.6mcg/kg without background infusion Type: Drug
Name: BL group: bolus 0.4mcg/kg with background infusion rate 0.2mcg/kg/hr Type: Drug
Name: BH group: bolus 0.2mcg/kg with background infusion rate 0.4mcg/kg/hr Type: Drug
Overall Status
Fentanyl based intravenous patient controlled analgesia(PCA)is popular method for postoperative pain control, but information regarding optimal dose of fentanyl in IV PCA is currently lacking. We thus determine appropriate dose of fentanyl (bolus dose and background infusion rate) for effective pain control with minimal side effects such as nausea and vomiting
