Over a 12-month period, 154 children were studied using i-gel® sizes ranging from 1 to 2.5 to assess the device based on successful rates of insertion, airway leak pressure, position confirmed by fibreoptic laryngoscopy, gastric tube placement, manipulations required, and complications. First insertion attempt was 93.5%, and complications arose in 20% of cases. Most were minor, however reports suggest there were cases of displacement and flexion compromising airway quality. Authors confirm ‘vigilance’ had to be used to secure the device, and that a decision on whether the higher cost for i-gel® is worth it depends on further studies of this kind.
