Aim: To evaluate the new pediatric Glidescope® (Cobalt GVL® Stat) by assessing the time taken to tracheal intubation under normal and difficult intubation conditions. We hypothesized that the Glidescope® would perform as well as conventional laryngoscopy.
Background: A new pediatric Glidescope® became available in October 2008. It combines a disposable, sterile laryngoscope blade and a reusable video baton. It is narrower and longer than the previous version and is available in a greater range of sizes more appropriate to pediatric use.
Methods: We performed a randomized study of 32 pediatric anesthetists and intensivists to compare the Cobalt GVL® Stat with the Miller laryngoscope under simulated normal and difficult airway conditions in a pediatric manikin.
Results: We found no difference in time taken to tracheal intubation using the Glidescope® or Miller laryngoscope under normal (29.3 vs 26.2 s, P = 0.36) or difficult (45.8 and 44.4 s, P = 0.84) conditions. Subjective evaluation of devices for field of view (excellent: 59% vs 53%) and ease of use (excellent: 69% vs 63%) was similar for the Miller laryngoscope and Glidescope®, respectively. However, only 34% of participants said that they would definitely use the Glidescope® in an emergency compared with 66% who would be willing to use the Miller laryngoscope.
Conclusions: The new Glidescope® performs as well as the Miller laryngoscope under simulated normal and difficult airway conditions. |
