Dexamethasone versus ondansetron in the prevention of postoperative nausea and vomiting in patients undergoing laparoscopic surgery: a meta-analysis of randomized controlled trials.

Wang XX, Zhou Q, Pan DB, Deng HW, Zhou AG, Huang FR, Guo HJ - BMC Anesthesiol (2015)

Bottom Line: We calculated pooled risk ratios (RR) and 95 % CIs using random- and fixed-effects models.There was no significant difference in the postoperative anti-emetics used (RR, 0.90; 95 % CI, 0.67-1.19; P = 0.45).Dexamethasone was as effective and as safe as ondansetron in preventing PONV.

ABSTRACT

Background: Dexamethasone is an antiemetic alternative to ondansetron. We aimed to compare the effects of dexamethasone and ondansetron in preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery.

Methods: We searched PubMed, Embase, Medline and Cochrane Library (from inception to July 2014) for eligible studies. The primary outcome was the incidence of PONV during the first 24 h after surgery. The secondary outcomes included PONV in the early postoperative stage (0-6 h), PONV in the late postoperative stage (6-24 h), and the postoperative anti-emetics used at both stages. We calculated pooled risk ratios (RR) and 95 % CIs using random- and fixed-effects models.

Results: Seven trials involving 608 patients were included in this meta-analysis, which found that dexamethasone had a comparable effectiveness in preventing PONV (RR, 0.91; 95 % CI, 0.73-1.13; P = 0.39) with that of ondansetron within 24 h of laparoscopic surgery, with no evidence of heterogeneity among the studies (I(2) = 0 %; P = 0.71). In the early postoperative stage (0-6 h), ondansetron was better at decreasing PONV than dexamethasone (RR, 1.71; 95 % CI, 1.05-2.77; P = 0.03), while in the late postoperative stage (6-24 h), dexamethasone was more effective in preventing PONV than ondansetron (RR, 0.51; 95 % CI, 0.27-0.93; P = 0.03). There was no significant difference in the postoperative anti-emetics used (RR, 0.90; 95 % CI, 0.67-1.19; P = 0.45).

Conclusions: Dexamethasone was as effective and as safe as ondansetron in preventing PONV. Dexamethasone should be encouraged as an alternative to ondansetron for preventing PONV in patients undergoing laparoscopic surgery.

Mentions: A total of 184 potentially relevant abstracts were identified. After duplicates were removed, one hundred and forty six unique abstracts remained. After reviewing the abstracts, only ten publications met the inclusion criteria. Three of them were excluded because of incomplete data. Finally, the remaining seven studies [1, 13–18] were included in the present meta-analysis. The search strategy and study selection are presented in the flow diagram of Fig. 1.Fig. 1
