Deep venous thrombosis (DVT) and pulmonary embolism (PE) are considered to be a major source of morbidity and mortality among trauma patients. Several reports have identified high-risk patients with recommendations for management ranging from frequent duplex scanning to placement of prophylactic inferior vena cava (IVC) filters. We reviewed our experience with a large trauma population to determine whether such approaches are justified. ⋯ Although these patients were at increased risk for thromboembolic events, the overall incidence of DVT was still extremely low with no apparent PE deaths. In our patient population, aggressive screening and prophylactic IVC filters would not have benefited 95% of "high-risk" patients without DVT and would not have prevented any deaths. We could not identify any population, except perhaps venous injuries, where such expensive and potentially harmful maneuvers seemed justified. Our experience with DVT and PE does not support either aggressive screening or prophylactic IVC filters as the standards of care.

Randomized Controlled Trial Clinical Trial
Prostaglandin E1 inhibits platelet decrease after massive blood transfusions during major surgery: influence on coagulation cascade?
A plunge in platelet count if often observed after massive blood transfusions during major surgery. This study was designed to assess whether the prophylactic administration of prostaglandin E1 (PGE1) might prevent this drop in platelet count. ⋯ In our study, the administration of PGE1 prevented a reduction in platelet count. Furthermore, measurements of clotting activity furnished the possibility that PGE1 might inhibit transfusion-induced coagulation disturbances. We recommend that PGE1 should be considered in patients requiring massive transfusion during major surgery.

Comparative Study
Resuscitation from hemorrhagic shock with diaspirin cross-linked hemoglobin, blood, or hetastarch.
An oxygen-transporting hemoglobin solution should be more effective than a nonhemoglobin solution for resuscitation from hemorrhagic shock. A way to evaluate this effectiveness is to determine whether a hemoglobin solution can reverse the base deficit accumulated during hemorrhage at a faster rate than a nonhemoglobin solution. Using this criterion, we compared the resuscitative powers of autologous blood, hetastarch (Het), and diaspirin cross-linked hemoglobin (DCLHb). ⋯ Based on the rate of base deficit correction and the volume of solution required, autologous blood was the most effective resuscitation solution. However, DCLHb was more effective than Het. DCLHb may be an attractive alternative to blood for resuscitation from hemorrhagic shock.

During the years 1987-1991, a statewide trauma system was implemented in Oregon (Ore) but not in Washington (Wash). Incidence of hospitalization, frequency of death and risk-adjusted odds of death for injured children (< 19 years) in the two adjacent states were compared for two time periods (1985-1987 and 1991-1993). ⋯ Both states show a similar temporal trend toward a declining frequency of death for children hospitalized with injuries. Injury prevention strategies appear to have reduced the number of serious injuries in both states. However, seriously injured children demonstrated a reduced risk of death in Oregon, consistent with benefit from a statewide trauma system.

Scapulothoracic dissociation is an infrequent injury with a potentially devastating outcome. The diagnosis has heretofore relied on the radiographic description of the forequarter disruption. Recent experience with four patients at a single trauma center, along with review of 54 injuries adequately described in the literature, indicates a broader spectrum of injury. ⋯ Identification of this injury requires clinical suspicion, based upon the injury mechanism and physical findings, to accurately assess the degree of trauma to musculoskeletal, neurologic, and vascular structures. Based upon these clinical findings, a rational approach to diagnostic techniques, injury classification, and appropriate surgical intervention can be achieved. Outcome is dependent on early recognition of the subset of patients with injuries amenable to surgical treatment and rehabilitation.
