Cervical extrication collars are applied to millions of blunt trauma victims despite the lack of any evidence that a collar can protect against secondary injuries to the cervical spine. Cadaver studies support that in the presence of a dissociative injury, substantial motion can occur within the occipitocervical spine with collar application or during patient transfers. Little is known about the biomechanics of cervical stabilization; hence, it is difficult to develop and test improved immobilization strategies. ⋯ Rigid cervical collars appear to create pivot points that shift the center of rotation lateral to the spine and contribute to the intervertebral motions that were measured. Immobilization strategies that avoid these neck pivot-shift phenomena may help to reduce secondary injuries to the cervical spine. The whole cadaver model with simulation of patient maneuvers may provide an effective test method for cervical immobilization.

Pharmacologic thromboprophylaxis (PTP) is frequently withheld, begun late, or interrupted in patients with traumatic brain injury (TBI). The purpose of this study was to analyze whether late or interrupted PTP increases the risk of venous thromboembolism (VTE) after TBI. ⋯ Interrupted administration of PTP in patients with TBI is associated with significantly increased risk of VTE. These findings underscore the importance of continuous PTP administration, and every effort should be made to avoid interruption if possible.

The yield of head computed tomography (CT) for patients who suffered head trauma with a presenting Glasgow Coma Scale (GCS) score of 15 has been reported to be low, even in patients who are anticoagulated or on antiplatelet therapy. We undertook this study to (1) determine the frequency of intracranial hemorrhage in anticoagulated patients and patients on antiplatelet therapy and its impact on clinical management, (2) identify predictors of positive imaging findings, and (3) assess potential differences between anticoagulation and antiplatelet therapy. ⋯ Despite a presenting GCS score of 15, patients with minor head injury from the trauma registry at our institution taking anticoagulation or antiplatelet therapy have a high incidence of intracranial hemorrhage especially after reported loss of consciousness.

In acute care surgery, predicting mortality is important to determine appropriate patient transfer to a regional emergency general surgery (EGS) center. We hypothesized that distance to a referral center and severity of illness (SOI) would be predictors of death. ⋯ Age, SOI, and distance from a regional referral center explain much of the variation in mortality and can be used for triage to regional EGS centers.

Chest trauma frequently occurs in severely injured patients and is often associated with hemorrhagic shock. Immune dysfunction contributes to the adverse outcome of multiple injuries. The aims of this study were to establish a combined model of lung contusion and hemorrhage and to evaluate the cardiopulmonary and immunologic response. ⋯ Although physiologic readouts were selectively altered in response to the single or double hits, the combination did not uniformly augment the changes in inflammation. Our results suggest that the leading insult regarding the immunologic response is lung contusion, supporting the concept that lung contusion represents an important prognostic factor in multiple injuries.
