NCT01428570

Brief Summary

The Pentax-AWS\_ system (AWS; Pentax Corporation, Tokyo, Japan) is a new rigid indirect laryngoscope which has an integrated tube passage function. Pentax-AWS improved the laryngeal view and facilitated tracheal intubation in patients with restricted neck motion. The purpose of this clinical trial was to evaluate the relative efficacy of the AWS laryngoscopes when used by experienced anesthetists in Obstructive Sleep Apnea Syndrome (OSAS) patients and to compare its performance with the Macintosh laryngoscope.
