A prospective, randomised and controlled test of 134 children, aged three months to 15 years old, undergoing general anaesthesia were inserted with either i-gel® size 1.5-3 or ProSealTM equivalent to gauge insertion performance. Outcome variables included leak pressure, ease of insertion, success rate and fibreoptic view. Most outcomes were very similar, however fibreoptic view was significantly better with i-gel®.
