Comparative Assessment of Three Approaches of Teaching Nonmedically Trained Persons in the Handling of Supraglottic Airways: A Randomized Controlled Trial.
The use of supraglottic airways has been recommended in combat trauma airway management. To ensure an adequate airway management on the battlefield, suitable training concepts are sought to efficiently teach as many soldiers as possible. Our aim was to compare three approaches of teaching laypersons in the handling of supraglottic airways in a mannequin model. ⋯ In this study, performed with personnel of the German Armed Forces, we have shown that persons without any medical and paramedical background are able to successfully place a supraglottic airway immediately following minimal instruction and after 3 months as well. Study participants achieved the best results after practical training followed by video presentation and finally lecture regardless of the airway device used. There are two possible reasons why practical training is the superior method. Firstly, the success is tied to more time spent with the learners. Secondly, practical training seems to be the best teaching method for various types of learners such as visual, auditory, reading/writing, and kinesthetic type. In addition the results of our study show that the LT-D is an ideal supraglottic airway in the hands of people inexperienced in airway management. In conclusion, our results show that practical training is the superior instruction method compared to theoretical lecture and presentation of an instruction video. Nevertheless, the presentation of an instruction video is a promising approach of teaching a maximum number of laypersons with minimal effort to correctly place supraglottic airways. To optimize the success rate of such a concept LT-Ds instead of LMAs should be used for airway management. The presented concepts hold promise for combat as well as for civilian emergency medicine.
