Summary

Generally, the laryngeal mask airway is not considered in the surgery which should be changing position in the perioperative period. The shape of the pharynx changes during the head and neck movement and there is probably also a change in the force transmitted to the cuff along the airway tube. Besides, there is evidence that supraglottic airway device can be displaced with rotation. In this article, the investigators want to discuss about that oropharyngeal leak pressure and sealing between the mask and vocal cord while changing head and neck position in perioperative period using different types of supraglottic airway device.

Conditions

It would be used to observe the leak pressure at 30,45,60 degree of the head and neck position and the condition between the vocal cord and peri-laryngeal region.

DEVICE

air Q LMA

It would be used to observe the leak pressure at 30,45,60 degree of the head and neck position and the condition between the vocal cord and peri-laryngeal region. The cuff pressure would be kept at 30 cm H20.

DEVICE

ambu LMA

It would be used to observe the leak pressure at 30,45,60 degree of the head and neck position and the condition between the vocal cord and peri-laryngeal region. The cuff pressure would be kept at 30 cm H20.
