Success rates with emergent endotracheal intubation (ETI) improve with increasing provider experience. Few objective metrics exist to quantify differences in ETI technique between providers of various skill levels. We tested the feasibility of using motion capture videography to quantify variability in the motions of the left hand and the laryngoscope in providers with various experience. Three providers with varying levels of experience (attending physician (experienced), Emergency Medicine resident (intermediate), and post doctoral student with no previous ETI experience (novice)) each performed ETI four times on a mannequin. A Vicon, 16-camera system tracked the 3D orientation and movement of markers on the providers, handle of the laryngoscope, and mannequin. Attempt duration, path length of the left hand and the inclination of the plane of the laryngoscope handle (mean squared angular deviation from vertical) were calculated for each laryngoscopy attempt. We compared inter-attempt and inter-provider variability of each measure All ETI attempts were successful. Mean (SD) duration of laryngoscopy attempts in seconds differed between experienced 5.50 (0.68), intermediate 6.32 (1.13) and novice 12.38 (1.06) providers (p=0.021). Mean path length of the left hand did not differ between providers (p=0.37). Variability of the plane of the laryngoscope (degrees2) differed between providers: 8.3 (experienced), 28.7 (intermediate) and 54.5 (novice). Motion analysis can detect inter-provider differences in hand and laryngoscope movements during ETI which may be related to provider experience. This technology has potential to objectively measure training and skill in ETI.
