PONV, neuromuscular paralysis
A cohort study involving 74 patients undergoing LBS indicated that 59% of the patients experienced PONV despite being treated with supra-optimal PONV prophylaxis [Bariatric surgery is a potential risk factor for PONV [Two points need to be further explained. First, neostigmine is a cholinesterase inhibitor commonly used as an antagonist for NMBDs-induced neuromuscular paralysis. Theoretically, neostigmine is thought to increase the risk of PONV, possibly by provoking gastric spasms, lowering barrier pressure, and increasing afferent input to central vomiting centers [Postoperative water intake and time to first flatus are two important indicators for evaluating recovery of gastrointestinal function. Early oral hydration following laparoscopic cholecystectomy is associated with lower incidence of PONV in the ward [This present study had some limitations. First, only patients with a BMI ≥ 35 kg/m
