Influence of sugammadex versus neostigmine for neuromuscular block reversal on the incidence of postoperative pulmonary complications: a meta-analysis of randomized controlled trials.

ABSTRACT

BACKGROUND: The influence of sugammadex for reversal of neuromuscular block (NMB) on postoperative pulmonary complications (PPCs), compared with neostigmine, remains to be determined. We performed a meta-analysis of randomized controlled trials (RCTs) to compare the incidence of PPCs between patients who received sugammadex versus neostigmine. METHODS: Relevant studies were obtained by searching the PubMed, Embase, and Cochrane Library databases. A random effects model incorporating the potential heterogeneity was used to pool the results. RESULTS: Fourteen RCTs including 1478 adult patients who underwent surgeries with general anesthesia were included, and of these, 753 received sugammadex and 725 received neostigmine for reversal of NMB. The pooled results showed that sugammadex was associated with a lower risk of overall PPCs compared to neostigmine (odds ratio [OR] 0.62, 95% confidence interval [CI] 0.43-0.89, p = 0.01; I2 = 0%). This finding remained consistent after exclusion of two studies with potential overlapping events (OR 0.58, 95% CI 0.36-0.96, p = 0.03; I2=9%). Stratified analyses according to the categories of PPCs showed that sugammadex was associated with a significantly lower risk of postoperative respiratory failure (OR 0.60, 95% CI 0.38-0.97, p = 0.04; I2 = 0%) but not of postoperative pulmonary infection (OR 0.79, p = 0.71), atelectasis (OR 0.78, p = 0.33), or pneumothorax (OR 0.87, p = 0.79). CONCLUSIONS: Compared with neostigmine, the use of sugammadex for reversal of NMB was associated with a lower risk of PPCs, mainly due to a lower incidence of postoperative respiratory failure with the use of sugammadex.
