BackgroundSugammadex is associated with fewer postoperative complications, but its impact on 30-day unplanned readmission is unclear.MethodsThis was a single-centre retrospective observational study of patients after major abdominal surgery between 2010 and 2017, where rocuronium was the only neuromuscular blocker used. The primary endpoint was the difference in incidence of 30-day unplanned readmission between reversal with sugammadex or neostigmine. The secondary endpoints were the length of hospital stay after surgery and related hospital charges (total charges excluding those related to surgery and anaesthesia). Analysis included propensity score matching and generalised mixed-effects modelling.ResultsMixed-effects logistic regression analysis of 1479 patients (sugammadex: 355; neostigmine: 1124) showed that the incidence of 30-day unplanned readmission was 34% lower (odds ratio [OR]: 0.66, 95% confidence interval [CI]: 0.46-0.96, P=0.031), the length of hospital stay was 20% shorter (exponential regression coefficient: 0.80, 95% CI: 0.77-0.83, P<0.001), and related hospital charges were 24% lower (exponential regression coefficient: 0.76, 95% CI: 0.67-0.87, P<0.001) in the sugammadex group than in the neostigmine group. For patients living ≥50 km from the hospital, the incidence of 30-day unplanned readmission was 68% lower in the sugammadex group than in the neostigmine group (OR: 0.32, 95% CI: 0.13-0.79, P=0.014), while it was not significant for patients living <50 km from the hospital (P=0.319).ConclusionsCompared with neostigmine, reversal of rocuronium with sugammadex after major abdominal surgery was associated with a lower incidence of 30-day unplanned readmission, a shorter hospital stay, and lower related hospital charges.Copyright © 2018 British Journal of Anaesthesia.
