Application of the LMA-Supreme™ and i-gel™ laryngeal masks during pelvic operations in adults

Objective: The aim of this study was to evaluate the practical application and safety of the i-gel and LMA-Supreme laryngeal masks for airway management during pelvic operations in adults. Methods: Ninety patients undergoing general anesthesia for elective pelvic operations (ASA Grades I-II) were randomly divided into two groups, the i-gel group and the Supreme group. The laryngeal mask was inserted after induction, and the relevant examination grading indexes were recorded. Results: The Supreme group required less time for laryngeal mask insertion and gastric tube indwelling time. Gastric tube indwelling was easier, compared with those in the i-gel group (p = 0.03), but the i-gel group had fewer complications (p = 0.03). There were no significant differences in the degree of difficulty in insertion, airway sealing pressure, PETCO2, Ppeak, and laryngeal mask alignment accuracy between the two groups (p > 0.05). There was no statistically significant difference in fibrobronchoscopy grading between the two groups (p > 0.05). Conclusion: The i-gel and LMA-Supreme laryngeal masks are safe and effective for airway management in patients during pelvic operations
