Does a deliberately restricted laryngeal view with the GlideScopeĀ® video laryngoscope facilitate tracheal intubation?

BEEM Bottom Line

Why is this study important?

Despite improved glottic visualization with the hyperangulated blade on the GlideScope video laryngoscope (GVL), passing the endotracheal tube (ETT) through an anterior glottis remains a common problem. This study comparatively evaluates a method to facilitate ETT passage by slightly withdrawing the GVL blade.[bjref i=”1″
