Out-of-hospital airway management with the LMA CTrach--a prospective evaluation.
OBJECTIVE
Airway management in an out-of-hospital setting is a critical and demanding skill. Previous studies evaluated the intubating laryngeal mask airway (ILMA) as a valuable tool in this area. The LMA CTrach Laryngeal Mask Airway (CTrach) may increase intubation success. Therefore, we evaluated the CTrach as the primary tool for airway management in the out-of-hospital setting in adult patients.


METHODS
From October 2006 until September 2007 EAN and SGR included all patients who needed advanced airway management during out-of-hospital emergency medicine service. Ventilation and intubation has been performed via the CTrach as the primary choice. Before intubation, visualization of the vocal cords was optimized under continuous ventilation via the CTrach. The time needed, manoeuvres to optimize vision, grades of vision and success rates have been documented.


RESULTS
16 patients have been included. Ventilation and intubation via the CTrach was possible in all patients. Ventilation was mostly established in less than 15s and was established in 15 of 16 (94%) patients at the first attempt. Intubation was successful in 15 of 16 (94%) patients on the first attempt. Visualization of the laryngeal structures was achieved in 69% of patients, while intubation without sight was performed in 31%, respectively.


CONCLUSIONS
In this study, ventilation and intubation via the CTrach was successful and could be rapidly established in all patients. Our data suggest that the use of the CTrach may be suitable for the out-of-hospital setting as it provides ventilation and facilitates intubation with a very high success rate.
