The purpose of this study was to determine the incidence of indirect spinal column injury in patients sustaining gunshot wounds to the head. ⋯ Indirect spinal injury does not occur in patients with gunshot wounds to the head. Airway management was compromised by cervical spine immobilization. Protocols mandating cervical spine immobilization after a gunshot wound to the head are unnecessary and may complicate airway management.

Lactate production after hemorrhagic shock may be produced by aerobic glycolysis, which has been linked to activity of the Na+/K+ pump in smooth muscle and other tissues. We tested whether increased muscle Na+/K+ pump activity after shock was linked to increased lactate production. ⋯ Hypoxia is unlikely to account for increased muscle lactate production after resuscitated hemorrhagic shock, because high lactate production persists under well-oxygenated incubation conditions. Inhibition of shock-induced lactate production by ouabain indicates energetic coupling of glycolysis to the Na+, K+-ATPase.

Recent attention concerning the adverse outcomes of blood transfusion has resulted in decreased blood product usage for nonemergency care. We hypothesized that there has also been a decrease in blood product use in the management of seriously injured adults. ⋯ Between 1991 and 1995 there have been significant reductions in both the number of trauma patients receiving blood products and the total number of units transfused. These findings may reflect lower or abandoned hemoglobin transfusion triggers and increased awareness of complications related to transfusion.

A prospective study of predictors of disability at 3 months after non-central nervous system trauma.
To delineate which injury-related, demographic, and psychosocial variables were predictive of severe disability (limitations in the performance of socially defined roles and tasks) at 3 months after discharge from acute hospitalization for non-central nervous system traumatic injury. ⋯ Extremity injuries, lack of high school graduation, and high level of posttraumatic psychological distress with intrusive thoughts are risk factors for severe disability at 3 months after discharge from the hospital.
