Impact of Sugammadex Versus Neostigmine Reversal on Postoperative Recovery Time in Patients With Obstructive Sleep Apnea Undergoing Bariatric Surgery: A Double-Blind, Randomized Controlled Trial
Bibliographic record
Abstract
BACKGROUND: Residual neuromuscular blockade can be associated with serious postoperative complications. Sugammadex is a newer neuromuscular blocking drug (NMBD) reversal agent that rapidly and completely reverses rocuronium. Whether sugammadex has any advantages over neostigmine in morbidly obese patients with obstructive sleep apnea (OSA) is unclear. We investigated whether sugammadex would reduce discharge time from the operating room (OR) compared with neostigmine in morbidly obese patients with OSA undergoing bariatric surgery. METHODS: This was a prospective, double-blinded randomized controlled superiority trial with 2 parallel groups. Patients were randomized 1:1 into reversal of NMBD with sugammadex or neostigmine. Our inclusion criteria were morbidly obese adult patients with OSA undergoing elective bariatric surgery under general anesthesia. Our exclusion criteria were allergy to rocuronium, sugammadex or neostigmine, malignant hyperthermia, hepatic or renal insufficiency, neuromuscular diseases, and an inability to give consent. The primary outcome was the time from administration of the NMBD reversal agent to discharge from the OR. Secondary outcomes included the time from administration of the NMBD reversal agent to the time the patient opened eyes to command, and the time to extubation. The Mann-Whitney test was used to compare the outcomes between treatment groups. RESULTS: We randomized 120 patients into 2 groups of 60 patients. Overall median body mass index (BMI) was 48.1 kg/m 2 ([interquartile range, IQR]) [43.0-53.5]. The time from drug administration to discharge from OR was 13.0 minutes [10.0-17.0] in the sugammadex group and 13.5 minutes [11.0-18.3] in the neostigmine group ( P = .27). The treatment effect estimate with a bootstrapped 95% confidence interval [CI] for time from admission to discharge from OR was -0.5 [-2.5 to 3]. No differences were observed in postoperative complications and other secondary outcomes. CONCLUSIONS: No difference was observed in OR discharge time in morbidly obese patients with OSA when sugammadex was administered instead of neostigmine.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
