Comparison between the Truview PCD? or the GlideScope? video laryngoscope and direct laryngoscopy for tracheal intubation in pediatric patients

摘要

In a randomized clinical trial, Riveros et al.1 compared the performance of the Truview PCD? or the Glide-Scope? video laryngoscope (GVL) with Macintosh laryngoscopy for tracheal intubation in children aged neonatal to ten years. Trial results showed that the lar-yngeal view obtained with the original GVL was significantly worse than that obtained with a Macintosh laryngoscope. The findings were not in agreement with those of two recent randomized studies in which a second generation Cobalt GVL provided a laryngeal view in children superior to that provided by direct laryngoscopy.2'3 Riveros et al. attributed their findings to the limited size options in the original GVL blades for the study participants. In our view, the unique characteristics of the Cobalt GVL blades vs the original GVL blades also account for differences in laryngeal visualization between the two recent studies and Riveros et a/.'s study.
