Background: The indications for immediate intubation in trauma are not controversial, but some patients who initially appear stable later deteriorate and require intubation. We postulated that initially stable, moderately injured trauma patients who experienced delayed intubation have higher mortality than those intubated earlier.
Methods: Medical records of trauma patients intubated within 3 h of arrival in the emergency department at our university-based trauma center were reviewed. Moderately injured patients were defined as an ISS < 20. Early intubation was defined as patients intubated from 10-24 min of arrival. Delayed intubation was defined as patients intubated ≥25 min after arrival. Patients requiring immediate intubation, within 10 min of arrival, were excluded.
Results: From February 2006 to December 2007, 279 trauma patients were intubated in the emergency department. In moderately injured patients, mortality was higher with delayed intubation than with early intubation, 11.8% versus 1.8% (P = 0.045). Patients with delayed intubations had greater frequency of rib fractures than their early intubation counterparts, 23.5% versus 3.6% (P = 0.004). Patients in the delayed intubation group had lower rates of cervical gunshot wounds than the early intubation group, 0% versus 10.7% (P = 0.048) and a trend toward fewer of skull fractures 2.9% versus 16.1%, (P = 0.054).
Conclusions: These findings suggest that delayed intubation is associated with increased mortality in moderately injured patients who are initially stable but later require intubation and can be predicted by the presence of rib fractures.
