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

SummaryObjectiveThe 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.MethodsNinety 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.ResultsThe 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).ConclusionThe i-gel and LMA-Supreme laryngeal masks are safe and effective for airway management in patients during pelvic operations.
