McGrath-MAC vs Macintosh laryngoscopes for child tracheal intubation during cardiopulmonary resuscitation☆,☆☆,★,★★ To the Editor, We read with interest the article of Szarpak et al [1] entitled “A comparison of the McGrath-MAC and Macintosh laryngoscopes for child tracheal intubation during resuscitation by paramedics” and published in the American Journal of Emergency Medicine. In this article, the authors aimed to evaluate the impact of cardiopulmonary resuscitation, with and without chest compressions, on the success rates and time to intubation with the Macintosh laryngoscope vs the McGrath video laryngoscope on a pediatric manikin. They found that McGrath video laryngoscope helps paramedics to intubate a pediatric manikin in a cardiopulmonary resuscitation scenario in less time and with fewer attempts than with the classical Macintosh, both in case of ongoing or stopped chest compressions. We congratulate the authors for this valuable study. In this study, participants were allocated to a sequence of 4 airway management procedures with one device, and then used the next one after a 15-minute break. We wonder whether the authors had observed a learning curve and whether these participants had a better time to intubation after the first attempt. It would also be of interest that each paramedic assessed the device used with a questionnaire related to
the ease of use, the speed of handling, or the visualization of the glottis and the vocal cords.
