Abstract

BackgroundNew laryngoscopes have become available for use in small children. The aim of the study was to compare the Storz® videolaryngoscope SVL to the Airtraq® Optical laryngoscope AOL for tracheal intubation in children younger than two years of age who had a normal airway assessment. Our hypothesis was that the SVL would have a better success rate than the AOL.

MethodsTen children aged 2 years or younger scheduled for elective cleft lip-palate surgery were included. The anesthesia was standardized and a Cormack-Lehane CL-score was obtained using a Macintosh laryngoscope. After randomization CL-score and endotracheal tube positioning in front of the glottis was performed with one device, followed by the same procedure and intubation with the other device. The video-feed was recorded along with real-time audio. The primary endpoint was the success rate, defined as intubation in first attempt. Secondary endpoints were the time from start of laryngoscopy to CL-score, tube positioning in front of the glottis, and intubation.

ResultsTwo intubation attempts were needed in two of five patients randomized to the SVL. The difference in time SVL vs. AOL to CL-score was 4.5 sec p = 0.0449. The difference in time SVL vs. AOL to tube positioning was 11.6 sec p = 0.0015. Time to intubation was 29.0 sec for SVL and 15.8 sec for AOL.

ConclusionNo difference in the success rate of endotracheal intubation could be established in this ten patient sample of children younger than two years with a normal airway assessment scheduled for elective cleft lip-palate surgery. However, the Airtraq® Optical videolaryngoscope showed a number of time related advantages over the Storz® videolaryngoscope. Because of the small sample size a larger trial is needed to confirm these findings. Both devices were considered safe in all intubations.
