Abstract

Background: Adequate relaxation of jaw muscles may influence both the ease and safety of laryngeal mask airway [LMA] insertion. This study aimed to assess whether low-dose atracurium could enhance LMA insertion conditions, reduce associated complications, and stabilize hemodynamic responses in patients undergoing ophthalmic surgery under general anesthesia induced by propofol.  
Patients and Methods: In this prospective, randomized, double-blind study, 40 patients were allocated equally into two groups. Group A received 0.1 mg/kg intravenous atracurium, while Group B received 2 mL of normal saline. Following administration of fentanyl and propofol for anesthesia induction, variables such as insertion time, ease of placement, jaw relaxation, number of attempts, hemodynamic changes, and adverse events were recorded.
Results: Low dose atracurium [0.1 mg/kg] reduced LMA insertion time [4.05 ± 0.53 vs. 5.03 ± 0.72 seconds, P < 0.001] and improved ease of insertion compared to the control group. No significant differences were found in hemodynamic parameters or postoperative sore throat.
Conclusion: Low-dose atracurium enhances LMA insertion conditions in ophthalmic surgery, with stable hemodynamics, making it a valuable tool for short-duration procedures.
