Diffuse axonal injury (DAI) is usually associated to severe trauma. Recent imaging advances made its diagnosis easier. Its prognosis impact is not yet well established. The aim of this article is to describe the epidemiologic, clinical, and radiologic features of posttraumatic DAI and to study its prognosis impact on mortality and outcome according to Glasgow Outcome Scale. ⋯ Dysautonomia, hyperglycemia, and subdural hematoma are the main factors associated to higher mortality when DAIs are diagnosed, whereas a DAI count≥6 is associated to poor outcome. Magnetic resonance imaging classification did not have a prognosis value even in patients with pure DAI.

Comparative Study
In-hospital mortality and surgical utilization in severely polytraumatized patients with and without spinal injury.
Patients who sustain major trauma experience multisystem injuries including those affecting the spine. We hypothesize that recovery after spinal injuries differs from those affecting other systems. The purpose of our study was to compare in-hospital mortality and surgical resource utilization in severely polytraumatized patient with and without spinal injury. ⋯ In this study, we conclude that the presence of a spinal injury in the setting of severe polytrauma (ISS>15) is associated with a prolonged course of ventilatory support, ICU, and in-hospital LOS. Trauma hospitals treating patients with spinal fracture should be aware of differences in the use of health services for this patient population.

Tachycardia is an important early sign of shock in trauma. Although the base deficit (BD) and lactate are indicative of hypoperfusion and known to predict mortality, some cases show a discrepancy between heart rate (HR) and BD or lactate; such cases have poor prognosis. The objective of this study was to examine whether lack of tachycardia after hypoperfusion is associated with increased mortality. ⋯ The lack of tachycardia in the presence of hypoperfusion is associated with poor prognosis independent of injury severity, SBP, and head injury. A discrepancy between HR and indicators of hypoperfusion could be considered as a predictor of mortality in trauma patients.

Postacute care is an essential component of medical care aimed at returning trauma patients to their preinjury functional status. Rehabilitation services, skilled nursing facilities, and home care all play a role in facilitating the healing process. Access to such care may be limited based on insurance status, leaving the uninsured with limited resources to reach full recovery. We hypothesized that access to specialized postacute care is less available to patients who lack health insurance. ⋯ Insurance status is an important predictor of hospital disposition and access to specialized posthospital care. Uninsured patients are less likely to have access to the full range of medical care available to ensure complete recovery from traumatic injuries.

Arterial base deficit (ABD) measurement is a standard test for assessment of the trauma patient's metabolic response to shock. Venous blood is readily available earlier during the trauma resuscitation. The aim of this study is to analyze the difference (correlation, agreement, clinical significance) between the first peripheral venous base deficit (pVBD) and the first ABD during trauma resuscitation. ⋯ There is near perfect correlation and clinically acceptable agreement between pABD and pVBD values on simultaneous testing. pVBD is an acceptable test to assess trauma patients' initial metabolic status when occult blood loss suspected.
