TI  - The GlideScope-specific rigid stylet and standard malleable stylet are equally 
      effective for GlideScope use.
PG  - 891-6
AB  - PURPOSE: The GlideScope videolaryngoscope usually provides excellent glottic 
      visualization, but directing an endotracheal tube (ETT) through the vocal cords 
      can be challenging. The goal of the study was to compare the dedicated 
      GlideScope-specific rigid stylet to the standard malleable stylet, assessed by 
      time to intubation (TTI). METHODS: Eighty patients requiring orotracheal 
      intubation for elective surgery were randomly allocated to either the GlideScope 
      rigid stylet (GRS) or a standard malleable stylet to facilitate intubation using 
      the GlideScope. Time to intubation was recorded by blinded assessors; operators 
      were blinded until after laryngoscopy. The operator assessed the ease of 
      intubation using a visual analogue scale (VAS). The number of intubation 
      attempts, number of failures, glottic grades, and use of external laryngeal 
      manipulation were documented. RESULTS: The median TTI was 42.7 sec 
      (inter-quartile range (IQR) 38.9-56.7) for the GRS group compared to 39.9 sec 
      (IQR 34.1-48.2) for the control group (P=0.07). The median VAS score for ease of 
      intubation was 20 (IQR 12.0-33.0) for the GRS group compared to 18 (IQR 9.5-29.5) 
      for the control group (P=0.21). There was no significant difference in TTI or VAS 
      between stylets. The overall incidence of a Cormack-Lehane grade I or II glottic 
      view was 98%. CONCLUSIONS: In a group of experienced operators using the 
      GlideScope, the dedicated GRS and the standard malleable ETT stylet are equally 
      effective in facilitating endotracheal intubation.
