Abstract
This meta-analysis was conducted to define clinical efficacy and side effects (bradycardia and post-operative nausea and vomiting [PONV]) in trials comparing sugammadex with neostigmine or placebo for reversal of rocuronium-induced neuromuscular blockade in adult patients. A search of PubMed, Google Scholar, and Cochrane Library electronic databases identified 111 clinical trials for potential inclusion. We performed a meta-analysis of 32 studies that quantitatively compared the efficacy and side effects of sugammadex with either neostigmine or placebo in adult patients requiring general anesthesia. Analyzed outcomes were reversal time, anesthesia time, duration of stay in the post-anesthesia care unit (PACU), and the occurrence of bradycardia or PONV. Odds ratios and 95% confidence intervals (CI) were calculated for binary data. Mean differences and 95% CI were calculated for continuous outcome data. Meta-analyses were performed using random and fixed-effects models. Heterogeneity across studies was assessed using Cochran's Q test and the I(2) statistic. Quantification of these outcomes can better inform anesthetists and health systems of the relative costs and benefits of the two reversal agents. This information also forms a basis for a comparative cost analysis in a co-submitted manuscript [1].
