Airway risk associated with patients in halo fixation.

BACKGROUND

The halo fixation device introduces a significant obstacle for clinicians attempting to secure a definitive airway in trauma patients with cervical spine injuries. The authors sought to determine the airway-related mortality rate of adult trauma patients in halo fixation requiring endotracheal intubation.

METHODS

This study was a retrospective chart review of patients identified between 2007 and 2012. Only adult trauma patients who were intubated while in halo fixation were included in the study.

RESULTS

A total of 46 patients underwent 60 intubations while in halo. On five occasions, (8.3%) patients were unable to be intubated and required an emergent surgical airway. Two (4.4%) of the patients out of our study population died specifically due to airway complications. Elective intubations had a failure rate of 5.8% but had no related permanent morbidity or mortality. In contrast to that, 25% of non-elective intubations failed and resulted in the deaths of two patients. The association between mortality and non-elective intubations was statistically highly significant ( = 0.0003).

CONCLUSION

The failed intubation and airway-related mortality rates of patients in halo fixation were substantial in this study. This finding suggests that the halo device itself may present a major obstacle in airway management. Therefore, heightened vigilance is appropriate for intubations of patients in halo fixation.
