Abstract:
Background:The effects of sugammadex, which reverses neuromuscular blockade, on emergence-related respiratory events in children remains unclear. This study compared the respiratory outcomes of sugammadex and neostigmine in pediatric tonsillectomy.
Methods:Children aged 2 years to 6 years old undergoing tonsillectomy were randomly assigned to sugammadex or neostigmine groups. The primary outcome was the occurrence of respiratory adverse events, including oxygen desaturation < 95%, airway obstruction, laryngospasm, bronchospasm, severe coughing, or postoperative stridor. Secondary outcomes included bradycardia, allergic reactions, and emergence delirium.
Results:The study included 172 pediatric patients (n = 86 per group). Neuromuscular blockade reversal was faster in the sugammadex group than in the neostigmine group, achieving a train-of-four ratio of 90% in a median of 1 min vs. 4 min in the neostigmine group (P < 0.001). The time to extubation was comparable between the two groups (median, 8 min; P = 0.679), as was the overall incidence of respiratory adverse events (29.0% vs. 30.2%; relative risk, 0.962; 95% confidence interval [CI], 0.607–1.524; P = 0.858). Emergence delirium occurred in 27.9% of patients overall, but the incidence was higher in the sugammadex group than in the neostigmine group (34.9% vs. 20.9%; relative risk, 1.214; 95% CI, 1.005–1.467; P = 0.044).
Conclusions:Sugammadex provides significantly faster neuromuscular blockade reversal compared to neostigmine but does not shorten the time to extubation or reduce the incidence of emergence-related respiratory adverse events in children undergoing tonsillectomy. Moreover, its use may be associated with an increased risk of emergence delirium.
