The 1999 American College of Surgeons resources for optimal care document added the requirement that Level I trauma centers admit over 240 patients with Injury Severity Score (ISS) > 15 per year or that trauma surgeons care for at least 35 patients per year. The purpose of this study was to test the hypothesis that high volume of patients with ISS > 15 per individual trauma surgeon is associated with improved outcome. ⋯ The significant independent predictors of survival in severely injured trauma patients are Ps, GCS score, age, mechanism of injury, and institutional volume. We found no statistically meaningful contribution to the prediction of survival on the basis of per-surgeon patient volume. Since this volume criterion for surgeon enpanelment and trauma center designation would not be expected to improve outcome, such a requirement should be justified by other measures or abandoned.

Intravenous administration of recombinant activated human clotting factor VII (rFVIIa) has been used successfully to prevent bleeding in hemophilia patients undergoing elective surgery, but not in previously normal trauma patients. This study was conducted to determine whether rFVIIa was a useful adjunct to gauze packing for decreasing blood loss from grade V liver injuries in hypothermic and coagulopathic swine. ⋯ rFVIIa reduced blood loss and restored abnormal coagulation function when used in conjunction with liver packing in hypothermic and coagulopathic swine. No adverse effects were identified.

Comparative Study
A population-based study of geriatric trauma in a rural state.
Urban geriatric trauma patients are known to die more often than their younger counterparts. Little is known of the fate of geriatric trauma patients in a rural environment where delays to definitive treatment are frequent. We hypothesized that rural trauma patients would do worse than their urban counterparts because of prolonged delays to definitive care. ⋯ In a rural environment, old trauma patients die more commonly in the hospital than their younger counterparts, who die more commonly at the scene. Old trauma patients who die in the hospital were less severely injured than their younger counterparts who died in the hospital. Old patients admitted to this rural trauma center have a significantly worse survival than their urban counterparts despite the fact that young rural trauma patients do significantly better than their urban counterparts. Understanding the demographics of rural geriatric trauma may be useful in allocating resources in rural trauma system design. It must be understood that despite relatively low injury severity and physiologic stability, there is a significant potential for rural geriatric trauma patients to do poorly.

To determine whether physical examination alone or in combination with biochemical markers can accurately diagnose hypoperfusion. ⋯ Combining physical examination with serum bicarbonate and arterial lactate identifies patients with hypoperfusion as defined by low Svo2 and cardiac index. Hypoperfusion may occur despite supranormal cardiac indices. Patients with cool extremities and elevated lactate levels may benefit from a pulmonary artery catheter to guide but not initiate therapy.
