A comparison of the STORZ video laryngoscope and standard direct laryngoscopy for intubation in the Pediatric airway--a randomized clinical trial.
Paediatr Anaesth. 2009 Nov; 19(11):1102-7.PA

Abstract

INTRODUCTION

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 degrees . 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 degrees . We studied the effectiveness of the STORZ DCI as an airway tool compared to standard direct laryngoscopy in children with normal airway.

METHODS

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.

RESULTS

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.

DISCUSSION

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.
