This retrospective audit identified an association between the introduction of unrestricted access to sugammadex and a fall in 'anaesthetic theatre time'. Mean hospital stay was also observed to be 0.8 days shorter after introduction of sugammadex, but was not statistically significant after adjusting for confounders.

AbstractThis retrospective casenote audit involving 374 patients requiring intubation for an anaesthetic found that when the availability of sugammadex became unrestricted, its use increased from 7.1 to 65.3% (P <0.0001) of all muscle relaxant reversals, while neostigmine use decreased from 59.6 to 12.5%. Rocuronium use decreased slightly (90.8 to 79.2%, P=0.006) but vecuronium use increased (2.1 to 8.3%, P=0.02). Cisatracurium and suxamethonium use were unchanged. Total rocuronium dose (55.9 ± 24.1 vs 60.4 ± 22.3 mg) and the number of doses (1.9 ± 1.48 to 1.96 ± 1.27) were unchanged, but the time between the last dose and reversal decreased (91.7 ± 68.1 to 62 ± 52.4 minutes, P=0.0002). There appeared to be no change in postoperative nausea and vomiting, or post-anaesthesia care unit time or oxygen saturation levels. Anaesthetic theatre time fell from 143.5 ± 85.8 to 120 ± 71.2 minutes (P=0.01) and remained significant when adjusted for confounding variables (ratio of means 1.17, 95% confidence interval 1.03 to 1.34, P=0.02), although inferences in relation to causality are limited by the retrospective and observational design of the study. Hospital stay also appeared to fall (4.2 ± 3.5 to 3.4 ± 3.0 days, P=0.035), but was not statistically significant when adjusted for confounding variables (ratio of means 1.04, 95% confidence interval 0.89 to 1.2, P=0.59). These observations suggest that the unrestricted availability of sugammadex will change how steroid-based neuromuscular blocking drugs are used and reversed, but further research is needed to determine if patient outcomes will improve.
