Comparison between three-way and standard laryngeal mask airways for children with pulmonary disorders undergoing diagnostic endoscopies
Abstract
Objective: To compare the safety and efficacy between a three-way laryngeal mask airway (TLMA) and a standard laryngeal mask airway (SLMA) in children with pulmonary disorders.
Methodology: We retrospectively analyzed 60 pediatric patients with pulmonary disorders who had surgical procedures with general anesthesia (oxygen flow rate: 1L/min) and volume control ventilation. Among the patients, 42 were inserted with TLMA (group T) and 18 were administered with SLMA (group S). Several parameters were obtained before, during and after the endoscopic procedure.
Results: Ease of insertion and the conditions during insertion were comparable in both groups. There were no significant differences between the two groups regarding changes in hemodynamic and blood gas parameters. However, patients in group S spent significantly longer time in surgery (group T: 35 ± 24 min compared with group S: 53 ± 31 min, P < 0.05) and ventilated (group T: 52 ± 26 min compared with group S: 68 ± 28 min, P < 0.05) than those in group T.
Conclusions: TLMA can be considered more effective for ventilation in children with pulmonary disorders who are undergoing general anesthesia.
