The intuitive use of laryngeal airway tools by first year medical students

The purpose of the study was to investigate the intuitive use of airway devices by first-year medical students as well as the effect of a simple, but well-directed training programme. Retention of skills was re-evaluated six months thereafter.The insertion of a LMA-Classic and a LMA-Fastrach performed by inexperienced medical students was compared in an airway model. The improvement on their performance after a training programme of overall two hours was examined afterwards.Prior to any instruction, mean time to correct placement was 55.5 ± 29.6 s for the LMA-Classic and 38.1 ± 24.9 s for the LMA-Fastrach. Following training, time to correct placement decreased significantly with 22.9 ± 13.5 s for the LMA-Classic and 22.9 ± 19.0 s for the LMA-Fastrach, respectively (p < 0.05). After six months, the results are comparable prior (55.6 ± 29.9 vs 43.1 ± 34.7 s) and after a further training period (23.5 ± 13.2 vs 26.6 ± 21.6, p < 0.05).Untrained laypersons are able to use different airway devices in a manikin and may therefore provide a secured airway even without having any detailed background knowledge about the tool. Minimal theoretical instruction and practical skill training can improve their performance significantly. However, refreshment of knowledge seems justified after six months.Mortality of "sudden cardiac death" (SCD) in Europe runs up to 375.000 patients per year [1] and is in most cases caused by acute (cardiac failure) coronary syndromes. To prevent secondary hypoxic damage to the brain and other vital organs due to respiratory failure, it is of paramount importance to assess and control the airway.Several devices have been recommended helping to keep the airway open [2]. While still bringing out the "gold-standard" with the tracheal tube, it has already been shown before that the laryngeal mask airway (LMA) and the Combitube are possible alternative tools. In comparison to bag-valve facemask ventilation, they may firstly reduce the risk of gastric regurg
