The i-gel LMA Is Similar to Ambu AuraOnce LMA for Pediatric Intubations

Researchers compared performance of the pediatric i-gel laryngeal mask airway (LMA) and the Ambu AuraOnce LMA in a prospective randomized study of 208 patients (age range, 0–17 years; weight range, 5–50 kg) undergoing elective surgery at an academic hospital in Switzerland. Trained observers measured leak pressures (primary outcome), insertion and ventilation success, insertion times, and adverse events. After three failed insertion attempts with the assigned device, the alternate device was used.

Demographic characteristics were similar in the two groups. No clinically significant differences were observed between the i-gel and Ambu groups in mean leak pressures or insertion times either overall (22 and 19 cm H₂O; 27 and 24 seconds, respect…
