Complications of a retrograde intubation in a trauma patient.

The authors report the case of an elder woman involved in a motor vehicle collision (MVC) requiring emergent intubation using the technique of retrograde intubation (RI). Since RI is a blind technique, potential complications arising from its use are numerous and may result in increased morbidity and mortality. Such was the case of this RI that involved incorrect placement of the endotracheal tube (ETT), resulting in suboptimal ventilation and increased morbidity. Additionally, this case illustrates how the failure to detect this error in multiple settings (ambulance, helicopter, emergency department) led to unnecessary and potentially deleterious procedures and significant delay in providing the basics of trauma care, oxygenation and ventilation. Although theoretical complications of RI have been addressed in the past, there have been very few published reports of actual complications. The emergency physician must be aware of difficult airways, options available to establish alternative airways, and methods to confirm appropriate placement of the ETT. The authors also discuss the indications, procedures, and complications involved in performing an RI.
