Cervical Spine Motion During Tracheal Intubation with Manual In-Line Stabilization: Direct Laryngoscopy versus GlideScope® Videolaryngoscopy

Abstract

During intubation under general anesthesia with neuromuscular blockade and manual in-line stabilization, the use of GVL produced better glottic visualization, but did not significantly decrease movement of the nonpathologic C-spine when compared with DL.
