Comparison of Coopdech®, CoPilot®, Intubrite®, and Macintosh laryngoscopes for tracheal intubation during pediatric cardiopulmonary resuscitation: a randomized, controlled crossover simulation trial

The aim of the study was to compare the intubation times and success rates of various laryngoscopes during resuscitation in pediatric emergency intubation with uninterrupted chest compression on a standardized pediatric manikin model. This was a randomized crossover study with 107 paramedic participants. We compared times to successful intubation, intubation success rates, and glottic visibility using a Cormack–Lehane grade for Macintosh, Intubrite®, Coopdech®, and Copilot® laryngoscopes. One hundred seven paramedics (mean age 31.2 ± 7.5 years) routinely involved in the management of prehospital care participated in this study. Intubation success rates (overall effectiveness), which was the primary study endpoint, were highest for the Coopdech® and CoPilot® devices (100 %) and were lowest for Intubrite® (89.7 %, p < 0.001) and Macintosh (80.4 %, p < 0.001). The secondary study endpoint, time to first effective ventilation, was achieved fastest when using the Coopdech® laryngoscope (21.6 ± 6.2 s) and was significantly slower with all other devices (Intubrite® 25.4 ± 10.5 s, p = 0.006; CoPilot® 25.6 ± 7.4 s, p = 0.007; Macintosh 29.4 ± 8.2 s, p < 0.001). Conclusion: We conclude that in child simulations managed by paramedics, the Coopdech® and Copilot® video laryngoscopes performed better than the standard Macintosh or Intubrite® laryngoscopes for endotracheal intubation during child chest compression.
