Effect of Head-neck Rotation on I-gel™ Insertion

Intubation; Difficult or Failed Clinical Trial

Official title: Effect of Head-neck Rotation on the Success Rate at First Attempt of I-gel™ Insertion

Status Completed

Clinical Trial Summary

According to previous studies, head and neck rotation reduces the tongue from being rolled back by gravity, which resulted in increasing patency of the upper airway. Therefore, the purpose of this study is to verify whether head and neck rotation increases the first attempt success rate of i-gel™.

Clinical Trial Description

I-gel™ insertion has been reported that the success rate of insertion on the first attempt is 78.5%. There may be several causes of insertion failure. Tongue folding is a major obstacle preventing appropriate i-gel™ placement. To solve this problem, the previous study has proven the efficacy of the rotational technical for I-gel™ insertion and reported a success rate of 97%. However, the rotation of i-gel™ in the oral cavity may be limited, and it may take some learning curve to get used to it. According to previous studies, head and neck rotation increases the cross-sectional area of the upper airway, which resulted in increasing patency of the upper airway. Therefore, the purpose of this study is to verify whether head and neck rotation increases the first attempt success rate of i-gel™. ;
