Erythropoietin (EPO) can exert acute hemodynamic and anti-inflammatory effects in addition to erythropoiesis. We tested the hypothesis that EPO given at resuscitation with saline will improve capillary perfusion and tissue oxygenation in the gut using a hemorrhagic shock model. ⋯ Our results suggest that the addition of rHuEPO at the time of saline resuscitation may have beneficial effects in hemorrhagic shock by improving tissue perfusion and decreasing dysoxia in the gut.

Supporting its therapeutic application in sepsis, p38 mitogen-activated protein kinase (MAPK) inhibition decreases cardiopulmonary injury and lethality with lipopolysaccharide challenge. However, only one preclinical study has reported the survival effects of a p38 inhibitor (SB203580, 100 mg/kg) during infection. We therefore tested SB203580 in mice (n = 763) challenged with intratracheal Escherichia coli and treated with antibiotics and fluids. ⋯ Thus, SB203580 had divergent effects on cardiac and lung function in E. coli challenged mice. Furthermore, high dose worsened survival and low dose did not improve it. Altogether, these findings suggest that clearly defining the risks and benefits of p38 MAPK inhibition is important before such treatment is applied in patients with or at risk of serious infection.

Abbreviated injury scale scoring in traffic fatalities: comparison of computerized tomography and autopsy.
The purpose of this investigation is to evaluate the value of postmortem computerized tomography (CT) for Abbreviated Injury Scale (AIS) scoring and Injury Severity Scoring (ISS) of traffic fatalities. ⋯ The most precise postmortem AIS and ISS scorings of traffic fatalities was obtained by a combination of AU and CT. If it is not possible to perform an AU, then CT may be used as an acceptable alternative for AIS scoring. We have identified one important obstacle for postmortem ISS scoring, namely that aorta ruptures are not easily detected by post mortem CT.

Hemorrhage remains a leading cause of early death in injured patients, and definitive control of bleeding remains a fundamental principle of trauma management. Therapeutic interventional radiology (IR) procedures have increasingly become essential in the acute management of traumatic injury. The importance of time to control of hemorrhage for therapeutic IR procedures has not been adequately characterized. ⋯ In hemodynamically unstable trauma patients undergoing therapeutic catheter-based IR procedures, delay to IR was independently associated with more than a twofold higher risk of mortality. These results suggest that therapeutic IR procedures should be performed as expeditiously as possible and held to the same dogma as applied to definitive operative control of hemorrhage.
