Applied Forces During Neonatal Intubation: a Randomized Crossover Mannequin Study

This is a randomized controlled crossover trial of intubation with three laryngoscope devices in a neonatal manikin model. Level III NICU and PICU consultants, pediatric residents, anesthesiology consultants, and anesthesiology residents will be eligible to participate in the study. Participants in the ABC arm will be assigned to perform the intubation with a traditional laryngoscope (A), followed by the intubation with a straight blade video laryngoscope (B) and by the intubation with hyper-angulated video laryngoscope (C). Participants in different arms will be assigned to perform the intubations in different sequences (BCA/CAB/ACB/BAC/CBA). The primary outcome measure will be the forces applied to mannequin oro-tracheal tissues during intubation with the three kinds of tools. The secondary outcome measures will be the perceived workload during intubation and intubation time with the traditional laryngoscope and the video laryngoscope.
