Abstrakt: Objective: Videolaryngoscopy (VL) in the prehospital setting remains controversial, with conflicting data on its utility. We compared C-MAC VL (Karl Storz, Tuttlingen, Germany) versus direct laryngoscopy (DL) in the prehospital setting, recording the grade of the glottic view, first pass success (FPS), overall success, and equipment functionality.
Methods: We conducted a prospective observational study with a convenience sample of 49 adult patients who were intubated by flight crew nurses and paramedics using the C-MAC videolaryngoscope from April to November 2013. We compared Cormack-Lehane (CL) grades of view for DL and VL, intubation success rates, and equipment functionality.
Results: CL grades 1 or 2 were obtained with 24 patients (49%) with DL and 45 patients (92%) with VL. Of the 25 patients (51%) who had a CL grade 3 or 4 view on DL, 22 of those patients (88%) converted to a CL grade 1 or 2 with VL (P < .001). There was an overall success rate of 96% and an FPS rate of 71%. The C-MAC videolaryngoscope was functional during intubation 100% of the time.
Conclusion: VL improved glottic visualization compared with DL. The FPS and overall intubation success rates were similar to other published prehospital studies using VL. The C-MAC provided reliable, high-quality video despite demanding prehospital conditions.
