To test the diagnostic utility of the triage serum glucose in differentiating major from minor injuries. ⋯ Serum glucose was as discriminating as BD or LAC in differentiating minor from major injury. An initial glucose >/=11.1 mMol/L had a low sensitivity (15%) but a high specificity (94%) for major injury.

Randomized Controlled Trial Comparative Study
Continuous noninvasive tissue oximetry in the early evaluation of the combat casualty: a prospective study.
We hypothesized that near-infrared spectroscopy (NIRS)-derived tissue oxygenation saturation (StO2) could assist in identifying shock in casualties arriving to a combat support hospital and predict the need for life-saving interventions (LSIs) and blood transfusions. ⋯ NIRS-derived StO2 obtained on arrival predicts the need for blood transfusion in casualties who initially seem to be hemodynamically stable (SBP >90). Further study of this technology for use in the resuscitation of trauma patients is warranted.

Multicenter Study Comparative Study
Multicenter validation of a simplified score to predict massive transfusion in trauma.
Several studies have described predictive models to identify trauma patients who require massive transfusion (MT). Early identification of lethal exsanguination may improve survival in this patient population. The purpose of the current study was to validate a simplified score to predict MT at multiple Level I trauma centers. ⋯ The ABC score is a valid instrument to predict MT early in the patient's care and across various demographically diverse trauma centers. Future research should focus on this score's ability to prospectively identify patients who will receive MT.

Comparative Study
Impact of policy change on US Army combat transfusion practices.
Clinical practice guidelines (CPGs) are used to keep providers up-to-date with the most recent literature and to guide in decision making. Adherence is typically improved although many have a muted impact. In March 2006, the US Army issued a damage control resuscitation CPG, encouraging 1:1 plasma:red blood cell (RBC) transfusions and limiting crystalloid use. The objective of this study was to determine whether the CPG was associated with a change in the transfusion practices in combat-wounded patients. ⋯ MT patients are now receiving a higher FFP:RBC ratio and less crystalloid after implementation of the CPG. Additionally, patients are now presenting normothermic and have higher hemoglobin levels. All of these changes are consistent with the principles of damage control resuscitation. Changes in practice were associated with implementation of the CPG, maturity of the battlefield, and increased availability of products.
