Comparison of the glidescope, CMAC, storz DCI with the Macintosh laryngoscope during simulated difficult laryngoscopy: a manikin study Full Text
BMC Anesthesiology, 06/22/2012
Healy DW et al. – Use of the Glidescope, CMA and Storz videolaryngoscopes improved the view of the glottis compared with use of the Macintosh blade .
Methods- A prospective randomized crossover study was performed comparing the performance features of the Macintosh Laryngoscope, Glidescope, Storz CMAC and Storz DCI videolaryngoscope.
- Thirty anesthesia providers attempted intubation with each of the 4 laryngoscopes in a high fidelity difficult laryngoscopy manikin.
- The time to successful intubation (TTSI) was recorded for each device, along with failure rate, and the best view of the glottis obtained.
- Use of the Glidescope, CMA and Storz videolaryngoscopes improved the view of the glottis compared with use of the Macintosh blade (GEE, p=0.000, p=0.002, p=0.000 respectively).
- Use of the CMAC resulted in an improved view compared with use of the Storz VL (Fishers, p=0.05).
- Use of the Glidescope or Storz videolaryngoscope blade resulted in a longer TTSI compared with either the Macintosh (GLM, p=0.000, p=0.029 respectively) or CMAC blades (GLM, p=0.000, p=0.033 respectively).
