Comparison of direct and video-assisted views of the larynx during routine intubation.

Objective: To compare the direct and indirect (video monitor) views of the glottic opening using a new Macintosh blade that is modified to provide a video image of airway structures during laryngoscopy.

Design: Prospective multicenter trial.

Setting: 11 university-affiliated hospitals.

A new video laryngoscope-an aid to intubation and teaching.

In recent decades, video techniques have been employed in the majority of endoscopic procedures because of several distinct advantages provided. These include the following: The displayed anatomy is magnified. Recognition of the anatomical structures and anomalies is easier, and manipulation of airway devices is facilitated.
