Comparative Study
Midline shift after severe head injury: pathophysiologic implications.
To investigate the mechanism of the adverse effect of midline shift after severe traumatic brain injury. ⋯ Midline shift after severe traumatic brain injury is associated with reduced CMRo2, regardless of whether or not SDH is present. The deleterious effects of subdural blood may be related more to the mass effect of large SDHs than to the biochemical abnormalities caused by small amounts of blood in the subdural space.

Trauma surgeons use a variety of methods to prevent venous thromboembolism (VT). The rationale for their use frequently is based on conclusions from research on nontrauma populations. Existing recommendations are based on expert opinion and consensus statements rather than systematic analysis of the existing literature and synthesis of available data. The objective is to produce an evidence-based report on the methods of prevention of VT after injury. ⋯ The trauma literature on VT prophylaxis provides inconsistent data. There is no evidence that any existing method of VT prophylaxis is clearly superior to the other methods or even to no prophylaxis. Our results cast serious doubt on the existing policies on VT prophylaxis, and we call for a large, high-quality, multicenter trial that can provide definitive answers.

To determine the factors predictive of mortality in patients with unstable pelvic fractures after successful transcatheter arterial embolization. ⋯ The success rate of embolization was 100% in stopping arterial hemorrhage of unstable pelvic fractures. The survival rate after successful embolization was 82.4%. Patients who had rapid blood transfusion before embolization had a poor final outcome. The risk of dying increased by 62% for every 1 unit/h increase of transfusion rate.

Maintaining left ventricular power output (LVP) > 320 mm Hg x L/min/m2 during resuscitation has been retrospectively associated with faster resolution of acidosis and survival after posttraumatic shock. The purpose of this prospective study was to evaluate the effects of maintaining LVP above this threshold during resuscitation on base deficit clearance, organ failure, and survival. ⋯ Prospectively maintaining LVP above 320 mm Hg x L/min/m2 during resuscitation is an achievable goal. It is associated with improved base deficit clearance and a lower rate of organ dysfunction after resuscitation from traumatic shock.

New York State instituted a statewide trauma system beginning in 1990. By 1993, that system included uniform emergency medical system triage guidelines, designated trauma centers, transfer agreements between trauma centers and noncenters, and a trauma registry containing data on seriously injured patients in each region and the state as a whole. We reviewed the first 4 years of registry data for the Finger Lakes Region to determine what effects the institution of a trauma system has had on the outcome of trauma care in this region. ⋯ Improved outcomes for patients with blunt trauma can occur early in the implementation of a trauma system. This improvement may be attributable in part to changes in field triage and early transport to trauma centers.
