Background: Low dose neuromuscular blockers, typically <2×ED95 or <0.46 mg/kg, have been shown to improve conditions of Laryngeal Mask Airway (LMA) placement and ease of ventilation during general anesthesia (GA), but its effects on the prevalence of residual neuromuscular blockage (rNMB) is poorly defined. A previous study in a large tertiary institution showed that 19% of patients undergoing GA with LMA received neuromuscular blockers. This study aims to audit the practice and establish the prevalence of rNMB.
Methods: A cross-sectional, observational study was designed. Patients were included if they received a low dose of atracurium (<2×ED95). Quantitative neuromuscular monitoring with electromyography was performed on emergence upon removal of LMA (Train of Four ratio <0.9).
