Can the ETView VivaSight SL Rival Conventional Intubation Using the Macintosh Laryngoscope During Adult Resuscitation by Novice Physicians?: A Randomized Crossover Manikin Study

Medicine (Baltimore). 2015 May;94(21):e850. doi: 10.1097/MD.0000000000000850.


The aim of this study was to assess the performance of the ETView VivaSight SL (ETView) single-lumen airway tube with an integrated high-resolution imaging camera in a manikin-simulated cardiopulmonary resuscitation scenario with and without chest compression. This was a randomized crossover manikin trial. Following a brief training session, 107 volunteer novice physicians who were inexperienced with airway management attempted to intubate a manikin using a Macintosh laryngoscope (MAC) and an ETView, with and without chest compressions. The participants were instructed to make 3 attempts in each scenario. In this trial, we compared intubation time, intubation success rates, and glottic visibility using a Cormack & Lehane Grade. Dental compression and ease of use of each device were also assessed. Median intubation times for the ETView and MAC without chest compressions were 17 (IQR, 15-19) s and 27 (IQR, 25-33) s, respectively (P < 0.001). The ETView proved more successful on the first intubation attempt than the MAC, regardless of compressions. Continuation of compressions caused an increase in intubation times for both the ETView (P = 0.27) and the MAC (P < 0.005). The ETView VivaSight SL is an effective tool for endotracheal intubation when used by novice physicians in a manikin-simulated cardiac arrest, both with and without chest compressions.
