Randomized Controlled Trial Multicenter Study Clinical Trial
Bactericidal/permeability-increasing protein (rBPI21) in patients with hemorrhage due to trauma: results of a multicenter phase II clinical trial. rBPI21 Acute Hemorrhagic Trauma Study Group.
Infection and organ failure are the most common causes of death or serious complication in trauma patients surviving initial resuscitation and operation. Of the many possible causes of these complications, bacterial translocation and release of harmful cytokines and oxygen free radicals may play an important role in the pathogenesis of the complications associated with traumatic hemorrhage. Recombinant human bactericidal/permeability-increasing protein (rBPI21) has antibacterial and antiendotoxin properties, reduces cytokine levels, and increases survival in animal models of hemorrhagic shock. The primary objective of this study was to evaluate the safety and efficacy of prophylactic rBPI21 infusion in patients with hemorrhage due to trauma. ⋯ rBPI21 was well-tolerated and demonstrated a favorable trend in reducing the composite primary end point of mortality or serious complication through day 15, especially respiratory complications, in patients with hemorrhage due to trauma. A phase III study is currently in progress.

Review Case Reports
Detection of vertebral artery injury after cervical spine trauma using magnetic resonance angiography.
We prospectively describe the incidence, magnetic resonance-based diagnosis, and treatment of vertebral artery (VA) injury resulting from closed cervical spine trauma. ⋯ Our data suggest that the incidence of VA injury in closed cervical spine trauma is significant and that FT fractures warrant flow-sensitive magnetic resonance imaging.

Comparative Study
Resuscitation with lactated Ringer's solution in rats with hemorrhagic shock induces immediate apoptosis.
We hypothesize that different resuscitative fluids may immediately affect the degree of apoptosis after hemorrhagic shock. ⋯ Resuscitation with LR solution after hemorrhagic shock increased immediate cell death by apoptosis in both the small intestine and liver. There was no significant increase in apoptosis in the animals resuscitated with hypertonic saline, whole blood, or in unresuscitated animals. Thus, the type of resuscitation fluid used may affect the apoptotic cellular response to shock.
