BackgroundThe value of the laryngeal tube S (LTS) for emergency airway management was evaluated in comparison to endotracheal intubation (ETI).MethodsPhysicians were asked to perform simulated airway management in an airway mannequin. The physicians were allocated into three groups according to their experience in intubation (1: <50, 2: >50, 3: >500 intubations). The success rate using LTS and ETI, the time needed for securing the airway, and the rating of both techniques by the participants were recorded.ResultsA correct position was achieved with the LTS in 99.39% of attempts (n=325), and with the endotracheal tube in 92.35% (n=302). Using the LTS it took an average time of 10.85 s to achieve the first successful ventilation, as compared to 17.75 s in ETI (p<0.0001). Participants from group 1 needed longer to achieve ETI in the 2nd (18.4 s vs. 16.4 s, p<0.0001) and 3rd attempts (16.9 s vs. 15.8 s, p<0.0001) compared to those from group 3.ConclusionsThe LTS represents a fast and reliable method to secure the airway and to achieve ventilation in the mannequin model described. The success rate, the time until successful ventilation and the rating by the participants indicates that the LTS is an important alternative to ETI. The LTS offers special benefits for the less experienced users.
