Rapid Sequence Airway (RSA)--a novel approach to prehospital airway management.

This article presents a case in which an air medical flight crew encountered a potentially difficult airway when a trauma patient deteriorated in-flight. The crew elected to sedate and paralyze the patient and place a laryngeal mask airway without a prior attempt at direct laryngoscopy and endotracheal intubation. The term Rapid Sequence Airway (RSA) is coined for this novel approach. This article describes and supports this concept and provides definitions of alternative and failed airways.
