Background:
I-gel® is a prototype among the second-generation supraglottic airway devices (SADs). The Ambu® AuraGain™ is a fairly new, single use, second-generation SAD with a preformed shape.
Aim:
To compare the oropharyngeal sealing pressure (OSP) of i-gel® and AuraGain™ in young children weighing between 5 and 20 kg.
Materials and Methods:
This study was conducted as a single-blinded randomized control trial at a tertiary care center over the period of 18 months. Forty children, aged between 6 months and 6 years, weighing 5–20 kg, belonging to the American Society of Anesthesiologists (ASA) Physical Status I, II, and III, undergoing elective surgical procedures, were randomized into two groups: the i-gel® group and Ambu® AuraGain™ group. The primary goal was measuring OSP at 1 min postinsertion and its change at 10 min. The secondary objectives were insertion time, success rate at first attempt, the degree of ease of gastric tube insertion, and perioperative adverse effects.
Results:
The mean OSP was significantly higher (
Conclusion:
Our study suggests that i-gel® is superior in achieving OSP, whereas gastric tube insertion is easy with the use of Ambu® AuraGain™.
