Abstract
OBJECTIVE: A systematic review and meta-analysis of published randomized controlled trials was performed to update the present evidence about the safety and efficacy of dexamethasone combined with other antiemetics versus single antiemetics for the prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy. METHODS: A computer literature search of PubMed, Scopus, Web of Science and Embase was conducted to identify the relevant randomized controlled trials. In addition, a manual search of reference lists of the retrieved articles was conducted. Relevant outcomes were pooled as odds ratio (OR) by RevMan version 5.3 for windows. RESULTS: Pooled data from 14 RCTs (1542 patients) favored dexamethasone combined with other antiemetics over single antiemetics as a prophylaxis against postoperative nausea and vomiting after laparoscopic cholecystectomy in the early postoperative period (OR = 0.39, 95% CI [0.27 to 0.54], p < 0.00001), late postoperative period (OR = 0.36, 95% CI [0.23 to 0.56], p < 0.00001), and overall postoperative period (OR = 0.34, 95% CI [0.23 to 0.51], p < 0.00001). Subsequently, rescue antiemetic usage was significantly lower in the combination group (OR = 0.25, 95% CI [0.16 to 0.41], p < 0.00001). Subgroup analysis showed that all combinations of dexamethasone and other antiemetics were superior to corresponding singel antiemetics except for the combination of dexamethasone and ramosetron which was not superior to ramosetron alone in all postoperative periods and the combination of dexamethasone and granisetron which was not superior to granisetron alone in the early postoperative period (OR = 0.26, 95% CI [0.07 to 1.01], p = 0.05). For all adverse events, there was no significant difference between the two groups. CONCLUSION: Dexamethasone combined with other antiemetics provided better prophylaxis than single antiemetics against postoperative nausea and vomiting after laparoscopic cholecystectomy. The underlying mechanism of dexamethasone action and its optimal dose should be further investigated.
