Purpose
Patients with rib fractures (RF) may require prolonged mechanical ventilation and tracheostomy. Indications for tracheostomy in trauma patients with RF remain debatable. The goal was to delineate characteristics of patients who underwent tracheostomy due to thoracic versus extra-thoracic causes, such as maxillofacial–mandibular injury (MFM), traumatic brain injury (TBI), and cervical vertebrae trauma (CVT), and to analyze clinical outcomes. The predictive values of chest trauma scoring systems for tracheostomy were also evaluated. We hypothesized that tracheostomized patients were more severely injured with more ribs fractured and had more pulmonary co-injuries.
Methods
Retrospective review included 471 patients with RF admitted to two Level 1 trauma centers. Patients with tracheostomy (n = 124, 26.3%) were compared to patients with endotracheal intubation (n = 347, 73.7%). Analyzed variables included age, gender, injury severity score (ISS), Glasgow Coma Scale, number of ribs fractured, total fractures of ribs, prevalence of bilateral rib fractures, flail chest, clavicle fractures, MFM, TBI, CVT, co-injuries, comorbidities, RF treatment options, hospital length of stay (HLOS), intensive care unit LOS (ICULOS), duration of mechanical ventilation (DMV).
Results
Tracheostomized compared to intubated patients had statistically higher ISS, more ribs fractured, total fractures of the ribs, bilateral and clavicle fractures, MFM, spine, chest, and orthopedic co-injuries and longer HLOS, ICULOS and DMV. Tracheostomy for thoracic reasons was performed in 64 patients (51.6%) and for extra-thoracic reasons in 60 patients (48.4%). Mean tracheostomy timing was 9.9 days and was significantly shorter in the extra-thoracic compared to the thoracic group (8.0 versus 11.6 days, p < 0.001). All chest trauma scoring system values were significantly higher in tracheostomized patients. Predictive values of scoring systems for tracheostomy increased in patients with thoracic trauma only.
Conclusions
A quarter of mechanically ventilated patients with RF required tracheostomy. Tracheostomized compared to intubated patients were more severely injured with more ribs fractured and were intubated longer. An increased amount of RF was associated with an increase in tracheostomies, especially for thoracic reasons.
