Stabilizing trauma victims in the out-of-hospital setting often requires the critical intervention of definitive airway management. Prehospital airway management studies in the U.S. have demonstrated variable success with endotracheal intubations by paramedics, ranging from 75-94% in recent well designed studies. Initial prehospital airway efforts showed there was a significant improvement in patient outcome when endotracheal intubation was performed in the field. Yet, a recent review cited 14 studies that demonstrated either no difference or even a higher mortality noted among patients that received prehospital endotracheal intubation by a paramedic. Of note, all of these previous studies were performed in non-combat settings and involved only civilian paramedics.
There currently are no prospective studies in the literature involving prehospital combat advanced airway management. Furthermore, it is not even clear how commonly advanced airway procedures are performed on the modern battlefield. Data from Vietnam shows that 6% of the soldiers killed in action suffered isolated airway injuries. In the current Global War on Terror, an estimated 27% of wounds occur to the head, neck or airway structures. Military databases demonstrate that patients requiring emergency airway management before reaching a combat support hospital constitute 5 to 10% of the total combat casualty population, and that acute airway compromise is a significant cause of preventable traumatic death in modern warfare. During Operation Iraqi Freedom, approximately 10% of the 3600 trauma patients that reached his Combat Support Hospital (CSH) had airway compromise as the primary cause of death. This may represent a conservative estimate given that it is not clear how many patients with airway compromise died on the battlefield and were never transferred to the CSH. In today's world, these findings are important to civilian physicians as well because of the parallels between combat settings and other austere environments such as wilderness medicine, medical support for law enforcement, and managing mass casualty effects of terrorist attacks and weapons of mass destruction.
The purpose of this study was to evaluate advanced airway management performance by prehospital providers during Operation Iraqi Freedom. Our intentions were to provide a preliminary analysis of prehospital airway management within the combat setting, and identify means of improving outcomes associated with prehospital endotracheal intubations. Other points of interest included gaining insight into which providers were at risk for performing incorrect intubations; theorizing how endotracheal intubations could be improved in the combat setting; and comparing the rate of missed intubations to previous studies performed in civilian settings.
This was a prospective, observational study performed under combat conditions during Operation Iraqi Freedom. This study was approved by the U.S. Army Clinical Investigation Regulatory Office. The primary outcome was independently physician verified correct placement of endotracheal tubes by prehospital providers within the combat setting.
