Sugammadex versus neostigmine for reversal of rocuronium-induced neuromuscular blockade: A randomized, double-blinded study of thoracic surgical patients evaluating hypoxic episodes in the early postoperative period.

This objective of this study was to determine if reversal of rocuronium-induced neuromuscular blockade with sugammadex versus neostigmine results in a decreased number of hypoxic episodes in the early postoperative period in patients undergoing thoracic surgery with single lung ventilation. Single-center, randomized, double-blind, two-arm clinical trial. Operating room and postanesthesia care unit. 92 subjects aged ≥18, American Society of Anesthesiologists physical status II-IV, and undergoing a thoracic operation necessitating single lung ventilation. Subjects received either 2 mg/kg sugammadex or 50 μg/kg neostigmine with 8 μg/kg glycopyrrolate for reversal of moderate neuromuscular blockade. For the first 90 min postoperatively, all episodes of hypoxia were recorded. Neuromuscular monitoring was performed with acceleromyography (TOF-Watch® SX) and the train of four (TOF) was recorded at 2, 5, 10, and 15 min after administration of the neuromuscular reversal agent. Subjects who received neostigmine had a median of 1 episode (interquartile range IQR: 0-2.2) of hypoxia versus subjects who received sugammadex who had a median of 0 episodes (IQR: 0-1) (p = 0.009). The mean time to recovery of TOF ≥ 0.9 was significantly faster with sugammadex at 10 min (95% confidence interval CI: 5-15) compared with neostigmine at 40 min (95% CI: 15-53) (p < 0.001). In thoracic surgical patients necessitating single lung ventilation, sugammadex provides faster reversal of moderate neuromuscular blockade and results in a decreased number of postoperative hypoxic episodes compared with neostigmine.
