Damage control resuscitation targets acute traumatic coagulopathy with the early administration of high-dose fresh frozen plasma (FFP). FFP is administered empirically and as a ratio with the number of packed red blood cells (PRBC). There is controversy over the optimal FFP:PRBC ratio with respect to outcomes, and their hemostatic effects have not been studied. We report preliminary findings on the effects of different FFP:PRBC ratios on coagulation. ⋯ Interim results from this prospective study suggest that FFP:PRBC ratios of ≥1:1 do not confer any additional advantage over ratios of 1:2 to 3:4. Hemostatic benefits of plasma therapy are limited to patients with coagulopathy.

Skull radiography is widely used to screen for fractures in patients with mild head injury. However, the clear depiction of a fracture requires a gap in the skull separated by the fracture that is wide enough to allow the passage of x-rays. We studied atypical linear fractures that were not visualized clearly, because a specific anatomical configuration hampered the passage of x-rays. ⋯ Radiographic study returned false-negative results, because x-rays were absorbed by the double-layered skull along fractures whose cross section was oblique to the direction of the x-rays. The evaluation of head injury by radiography only may miss these fractures and their undetected presence may result in sequelae such as intracranial hematoma.

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.
