BackgroundThe visibility and quality of the tracheal intubation may be improved by the video intubating laryngoscope (VIL). However, the efficacy using VIL among novice residents has not been reported.MethodsTotal of 154 cases of tracheal intubation experienced by 5 novice residents in 8 weeks were divided into VIL (X-Lite: Rüsch, Germany) group (n = 59) and ordinary laryngoscope group (OL: n = 95), retrospectively. Number of attempts, success and failure were recorded in both groups. In VIL group, video image of the entire procedure was recorded. Success rates were compared between OL and VIL. In VIL group, elapsed time for intubation and findings during laryngoscopic procedure were examined retrospectively.ResultsIn the first attempt, the success rate was significantly higher in VIL (83%) than OL (68%). Including secondary attempt, the rate increased to 85% in OL and 97% in VIL, and the difference was also significant. In VIL group, elapsed time for entire intubation was 42 +/- 18 seconds (mean +/- SD). It was significantly decreased in 4, 6 and 7th week compared in the first week. Residents showed different pattern of findings during their laryngoscopic procedure.ConclusionsThe use of VIL improved success rate of tracheal intubation compared with OL. Retrospective analysis of video image revealed their progress and characteristics features in their laryngoscopic procedure. VIL was efficient in the education of the novice residents.
