Constant-rate Infusion
Variable-rate Feedback Infusion
INTERVENTION : Constant-rate Infusion mode : The PCA regimen consisted of fentanyl 20 μg/kg and Ramosetron Hcl 0.3 mg (total volume including saline: 100 ml) and was programmed to deliver 1 ml /h as a background infusion and a bolus of 1.5 ml on-demand, with a 15 min lockout time during a 48 h period
INTERVENTION : Variable-rate Feedback Infusion mode :The PCA regimen consisted of fentanyl 20 μg/kg and Ramosetron Hcl 0.3 mg (total volume including saline: 100 ml) and was programmed to deliver 1 ml /h as a background infusion and a bolus of 1.5 ml on-demand, with a 15 min lockout time.
