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™.

Detailed 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™.

Conditions

• Supraglottic Airway Device
• Intubation; Difficult or Failed
• Airway Complication of Anesthesia

Interventions

Type	Name	Description
PROCEDURE	Standard method	Insert I-gel™ according to the manufacturer's instruction. Take the sniffing position and gently move the i-gel™ along the hard palate to the soft palate and the posterior oropharynx.
PROCEDURE	Hean and Neck Rotation	After rotating the patient's head and neck to the left maximally, insert the i-gel™ from the right side of the tongue to the midline. When the tip reaches the soft palate and oropharynx positions, turn the head and neck back to the neutral position.
