To study the viability, reliability, and validity of the Spanish version of the Burn-Specific Health Scale. ⋯ The Spanish version of the Burn-Specific Health Scale is a reliable and valid instrument for use in the Spanish population, and its results are perfectly comparable with those obtained in the original English version.

Hemoglobin-based blood substitutes may cause vasoconstriction, which could limit organ perfusion during trauma resuscitation. We investigated the effect of two hemoglobin solutions on regional blood flow and mucosal perfusion in the gastrointestinal tract in a hemorrhagic shock model. ⋯ PHP was efficacious in restoring CI and small-bowel flow, but the pHi remained low, indicating possible continued mucosal ischemia. Alpha(alpha)Hb led to limited recovery of CI and small-bowel blood flow but restored pHi close to baseline. Shed blood was efficacious in restoration of pHi, gastrointestinal blood flows, and systemic hemodynamics.

Changes in the management of torso gunshot wounds (TGSWs) have evolved in recent years as a result of differences between military and civilian injuries and increasing interest in avoiding nontherapeutic invasive procedures. The objective of this study was to establish the utility and accuracy of computed tomography (CT) in the evaluation of selected patients with TGSWs. ⋯ CT of selected TGSW patients is safe and may reduce the incidence of invasive diagnostic procedures. A prospective evaluation of CT for TGSW patients is warranted.

Glasgow Coma Scale (GCS) scoring is enigmatic in intubated patients. To determine if there is consensus among Level I trauma centers, a national telephone survey was conducted. ⋯ Wide variation in GCS scoring among Level I trauma centers was identified. Because GCS scores are used in treatment algorithms, trauma scoring, and outcome prediction (Trauma and Injury Severity Score), uniform scoring is essential and should be pursued. Use of state and national databases and outcome research may be adversely affected by the lack of consistent GCS scoring.

Tachycardia is considered a physiologic response to traumatic hypotension. The inability of the heart to respond to shock with tachycardia has been described as paradoxical bradycardia or relative bradycardia. The incidence and clinical significance of this condition in major trauma is not known. The objective of this study was to examine the incidence and prognostic significance of tachycardia and relative bradycardia in patients with traumatic hypotension. Relative bradycardia is defined as a systolic pressure < or = 90 mm Hg and a pulse rate < or = 90 beats per minute. ⋯ Relative bradycardia in hypotensive trauma patients is a common hemodynamic finding. Mortality among tachycardic patients was more predictable than among bradycardic patients using commonly used demographic and injury indicators. The presence of relative bradycardia in some subgroups of patients with severe injuries seems to be associated with better prognosis than the presence of tachycardia.
