Study type
Interventional
Description of intervention(s) / exposure
A total of 120 ASA physical status I and II were included in this randomized, double-blind, placebo-controlled study. Patients were randomly assigned to 3 groups (n=40) before induction of anesthesia. Patients of group dexamethasone (group D) were administrated 8 mg dexamethasone intravenous infusion before induction of anesthesia. Patients of group propofol (group P) were infused to sub hypnotic (1 mg/kg/h) propofol during operation. Patients of group control (group C) were applied infusion of 10% intralipid until the end of surgery. The incidence of PONV, needs for rescue analgesic and antiemetic were recorded in the first 24 h postoperatively.

Treatment: Drugs
Comparator / control treatment
Group P and group C received isotonic saline solution in 2 ml before induction of anesthesia. Patients of group control (group C) were applied infusion of 10% intralipid until the end of surgery.

Placebo

Outcomes
Primary outcome [1] 292415 0
The primary aim of this prospective, randomized, double blind, placebo-controlled study was to evaluate the efficacy of dexamethasone and continuous infusion of sub hypnotic propofol to prevent PONV in patients undergoing laparoscopic cholecystectomy.PONV will be assessed using a four-point ordinal scale (0=none, 1=nausea, 2=nausea with request for antiemetic, 3=vomiting)
Timepoint [1] 292415 0

Secondary outcome [1] 308898 0
Secondary aim of this study was to determine the rescue antiemetic and analgesic in the first 24 hours after laparoscopic cholecystectomy

Statistical methods / analysis
Before study, sample size was determined by power analysis, assuming that the total incidence of PONV in the placebo group would be 70%, with a 35% reduction in the incidence of PONV in the treatment group with alpha error was set at 0.05 and beta error at 0.2. According to power analysis, any group size of 31 patients was considered adequate. We decided to enroll 40 patients per group to allow dropout. The post-hoc test which was held during the statistical evaluation showed 31 patients for the propofol group and 35 patients for the dexamethasone group were needed. Statistical analysis was performed using the program of SPSS20. One way ANOVA was used to compare the differences of numeric data among the groups. Chi-squared test was used for categorical data. Level of significance was set at p < 0.05.
