Prehospital airway management using the laryngeal tube. An emergency department point of view

Abstract

Background: Competence in airway management and maintenance of oxygenation and ventilation represent fundamental skills in emergency medicine. The successful use of laryngeal tubes (LT, LT-D, LTS II) to secure the airway in the prehospital setting has been published in the past. However, some complications can be associated with the use of a laryngeal tube.

Methods: In a nonconsecutive case series, problems and complications associated with the use of the laryngeal tube in prehospital emergency medicine as seen by independent observers in the emergency room are presented.

Results: Various problems and possible complications associated with the use of a laryngeal tube in eight case reports are reported: incorrect placement of the laryngeal tube in the trachea, displacement and/or incorrect placement of the laryngeal tube in the pharynx, tongue and pharyngeal swelling with subsequently difficult laryngoscopy, and inadequate ventilation due to unrecognized airway obstruction and tension pneumothorax.

Conclusion: Although the laryngeal tube is considered to be an effective, safe, and rapidly appropriable supraglottic airway device, it is also associated with adverse effects. In order to prevent tongue swelling, after initial prehospital or in-hospital placement of laryngeal tube and cuff inflation, it is important to adjust and monitor the cuff pressure.
