Efficacy and Safety of Sugammadex versus Neostigmine in Reversing Neuromuscular Blockade in Morbidly Obese Adult Patients: A Systematic Review and Meta-Analysis.

Abstract

Context:Sugammadex is known to reverse neuromuscular blockade (NMB) more rapidly and reliably than neostigmine. However, data remain limited in bariatric patients. In this review, we systematically evaluated the efficacy and safety of sugammadex versus neostigmine in reversing NMB in morbidly obese (MO) patients undergoing bariatric surgery.Aims:Our primary objective was to determine the recovery time from drug administration to a train-of-four (TOF) ratio >0.9 from a moderate or deep NMB.Settings and Design:This systematic review and meta-analysis (SR and MA) was conducted in accordance with the Preferred Items for SRs and MAs guidelines.Subjects and Methods:A systematic search was conducted within multiple databases for studies that compared sugammadex and neostigmine in MO patients.Statistical Analysis Used:We reported data as mean difference (MD) or odds ratios (OR) and corresponding 95% confidence interval (CI) using random-effects models. A two-sided P < 0.05 was considered statistically significant.Results:Seven studies with 386 participants met the inclusion criteria. Sugammadex significantly reduced the time of reversal of moderate NMB-to-TOF ratio >0.9 compared to neostigmine, with a mean time of 2.5 min (standard deviation [SD] 1.25) versus 18.2 min (SD 17.6), respectively (MD: −14.52; 95% CI: −20.08, −8.96; P < 0.00001; I2 = 96%). The number of patients who had composite adverse events was significantly lower with sugammadex (21.2% of patients) compared to neostigmine (52.5% of patients) (OR: 0.15; 95% CI: 0.07–0.32; P < 0.00001; I2 = 0%).Conclusions:Sugammadex reverses NMB more rapidly with fewer adverse events than neostigmine in MO patients undergoing bariatric surgery.
