Using the predictive model of difficult endotracheal intubation to examine different simulators for airway management training: a pilot cross-sectional observational study

Intubation parameters were recorded for comparison across subgroups. Mean intubation times for models A, B, and D were 42.67 ± 15.32 seconds, 48.73 ± 17.54 seconds, and 50.22 ± 18.40 seconds, with success rates of 89.47%, 78.95%, and 68.42%, respectively. Model 'C' had the highest difficulty score (4.430 points), the longest intubation time (58.84 ± 22.63 seconds, P <.001), and the lowest success rate (57.89%, P <.001), and was rated most difficult by participants. Notably, subsequent intubation attempts showed reduced time and complexity compared to the initial one.In conclusions, our devised scoring metric demonstrated a remarkable congruence with the tangible outcomes of the challenging endotracheal intubation training model. This outcome lends credence to the potential applicability of our formula not only in assessing the intricacy of existing models but also as a guiding benchmark for the innovation and refinement of novel training manikins.
