Endotracheal intubation is still the gold standard in airway management. For medical
students and young professionals, it is often difficult to train personal skills. We tested a high-fidelity
simulator with an additional quantitative feedback integration to elucidate if competence acquisition
for airway management is increased by using this feedback method. In the prospective trial, all
participants (n = 299; 4th-year medical students) were randomized into two groups—One had been
trained on the simulator with additional quantitative feedback (n = 149) and one without (n = 150).
Three simulator measurements were considered as quality criteria—The pressure on the upper front
row of teeth, the correct pressure point of the laryngoscope spatula and the correct depth for the
fixation of the tube. There were a total of three measurement time points—One after initial training
(with additional capture of cognitive load), one during the exam, and a final during the follow-up,
approximately 20 weeks after the initial training. Regarding the three quality criteria, there was only
one significant difference, with an advantage for the control group with respect to the correct pressure
point of the laryngoscope spatula at the time of the follow-up (p = 0.011). After the training session,
the cognitive load was significantly higher in the intervention group (p = 0.008) and increased in both
groups over time. The additional quantitative feedback of the airway management trainer brings no
measurable advantage in training for endotracheal intubation. Due to the increased cognitive load
during the training, simple airway management task training may be more efficient for the primary
acquisition of essential procedural steps.
