Abstract
Direct laryngoscopy can be challenging in infants and neonates. Even with an optimal line of sight to the glottic opening, the viewing angle has been measured at 15°. The STORZ DCI video laryngoscope (Karl Storz, Tuttlingen, Germany) incorporates a fiberoptic camera in the light source of a standard laryngoscope of variable sizes. The image is displayed on a screen with a viewing angle of 80°. We studied the effectiveness of the STORZ DCI as an airway tool compared to standard direct laryngoscopy in children with normal airway.In this prospective, randomized study, 56 children (ages 4 years or younger) undergoing elective surgery with the need for endotracheal intubation were divided into two groups: children who underwent standard direct laryngoscopy using a Miller 1 or Macintosh 2 blade (DL) and children who underwent video laryngoscopy using the STORZ DCI video laryngoscope with a Miller 1 blade (VL). Time to best view (TTBV), time to intubate (TTI), Cormack-Lehane (CL), and percentage of glottis opening seen (POGO) score were recorded.TTBV in DL was 5.5 (4-8) s and 7 (4.2-9) s in VL. TTI in DL was 21 (17-29) s and in VL 27 (22-37) s (P = 0.006). The view as assessed by POGO score was 97.5% (60-100%) in DL and 100% (100-100%) in the VL (P = 0.003). Data are presented as median and interquartile range and analyzed using t-test.This study demonstrates that the STORZ DCI video laryngoscope provides an improved view to the glottis in children with normal airway anatomy, but requires a longer time for intubation.
