Biliary leak after severe hepatic trauma is a complex problem requiring multidisciplinary care. We report on our experience with endoscopic management of posttraumatic bile leaks and clarify the role of endoscopic retrograde cholangiopancreatography (ERCP). ⋯ ERCP is useful as both a diagnostic and therapeutic tool for the safe treatment of biliary ductal injuries after severe liver trauma and should be part of a multidisciplinary treatment algorithm.

Delivery of a high ratio of plasma to packed red blood cells to patients who require massive transfusion is associated with improved survival. Hemorrhagic shock causes increased production of pro-inflammatory cytokines. These are associated with late morbidity and mortality. The use of fresh frozen plasma makes high ratio resuscitation logistically difficult and does not address dysfunctional inflammation. Lyophilized plasma (LP) is a stable powdered form of plasma that is both safe and easily reconstituted. Previous work demonstrated that LP reconstituted with ascorbic acid (AA) decreased inflammation. Whether the reduction of inflammation was associated with LP or the AA is unknown. ⋯ In this animal model of trauma, hemorrhage and resuscitation, AA decreases IL-6 expression relative to CA and HCl. These findings confirm previous work from our laboratory and suggest that AA is responsible for suppression of dysfunctional inflammation in this model.

Recognition of trauma-induced coagulopathy by conventional coagulation testing (CCT) is limited by their slow results, incomplete characterization, and their poor predictive nature. Rapid thrombelastography (r-TEG) delivers a more comprehensive assessment of the coagulation system but has not been prospectively validated in trauma patients. The purpose of this pilot study was to evaluate the timeliness of r-TEG results, their correlation with CCTs, and the ability of r-TEG to predict early blood transfusion. ⋯ Graphical r-TEG results are available within minutes, correlate with conventional coagulation test that are not as rapidly available, and are predictive of early transfusions of packed red blood cells, plasma, and platelets.

The effect of blood component ratios on the survival of patients with traumatic brain injury (TBI) has not been studied. ⋯ High platelet ratio was associated with improved survival in TBI+ patients while a high plasma ratio was associated with improved survival in TBI- patients. Prospective studies of blood product ratios should include TBI in the analysis for determination of optimal use of ratios on outcome in injured patients.

Comparative Study
Cost-utility analysis of levetiracetam and phenytoin for posttraumatic seizure prophylaxis.
The standard for early posttraumatic brain injury (TBI) seizure prophylaxis is phenytoin. Despite its effectiveness, some argue for the use of newer antiepileptics (e.g., levetiracetam) because phenytoin requires close monitoring to maintain its therapeutic window and is associated with rare cutaneous hypersensitivity reactions. The purpose of this study was to evaluate whether phenytoin or levetiracetam would be more cost-effective in preventing early post-TBI seizures and reducing their negative impact on TBI outcomes. ⋯ Phenytoin is more cost-effective than levetiracetam at all reasonable prices and at all clinically plausible reductions in post-TBI seizure potential.
