Laryngeal Mask, Laryngeal Tube, and Frova Introducer in Simulated Difficult Airway
چکیده انگلیسی

BackgroundThe use of supraglottic devices is rising in the prehospital management of difficult airway; moreover, we think that patients with multiple trauma or cervical instability can take advantage of these devices without opening or retiring the cervical collar.ObjectiveTo compare speed and ease of use between Laryngeal Tube S (LTS) and the Ambu AuraOnce laryngeal mask (LMA).Our second objective was to evaluate changing these devices to an endotracheal tube (ETT) using a Frova introducer.MethodsWe studied the use of LTS and LMA in an experimental model, represented by a manikin with a rigid cervical collar and a limited mouth opening. This study was carried out in Complutense University of Madrid with 145 2nd-year students for the degree in Dentistry who have knowledge of the airway but lack experience in intubation. Number of attempts and time for the device’s insertion were measured, as well as time for the exchange maneuver using the Frova introducer.ResultsInsertion of all devices was possible on the first attempt; time for insertion was LTS 12.2 ± 1.28 s and LMA 6.87 ± 0.97 s. Once these devices were inserted, a Frova introducer is used to perform an exchange by an endotracheal tube; all devices could be exchanged on the first attempt, and exchange time was LTS 26.9 ± 1.2 s and LMA 16.79 ± 1.32 s. Results for both time for insertion and exchange of the LMA were significantly lower than those for the LTS (p < 0.001).ConclusionThe method used can be considered quick and easy, even for personnel inexperienced in intubation. This exchange maneuver has not been described previously, so we can consider it as a new application of the Frova introducer.
