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.

Continuous renal replacement therapy (CRRT) is the preferred mode of renal replacement therapy in patients with acute brain injury (ABI). There are limited data available describing the effects of CRRT on intracranial pressure (ICP). This study aims to evaluate changes in ICP during CRRT in patients after ABI. ⋯ CRRT may have beneficial effects in patients with RIH. Given the high mortality rate and poor neurological outcome associated with RIH, further research may be warranted.

The purpose of this study was to determine whether trauma patients who are intubated because of combativeness, and not because of medical necessity, have more complications resulting in longer lengths of stay. ⋯ The results from this study indicate that trauma patients who are intubated because of combativeness, and not because of medical necessity, have longer lengths of stay, increased incidence of pneumonia, and poorer discharge status when compared with matched controls. The outcomes of this group are similar to that of patients who are intubated because of medical necessity.

Ultrasonography has been widely applied in clinical settings, and its role in the assessment of trauma has been approved. However, there are very few reports about its role in the management of mass casualties. ⋯ In our hospital, ultrasonography was widely used in the triage of earthquake victims, bedside examination of severe cases, and interventional treatments. The advantages of ultrasonography such as convenience, noninvasiveness, high accuracy, and repeatability have been sufficiently demonstrated in this mass casualty, where ultrasonography played a great role in the rescue of victims of Wenchuan earthquake.

Tissue injury from mechanical trauma modulates innate immunity. The resultant systemic inflammatory response syndrome (SIRS) closely mimics clinical sepsis, and bacterial n-formyl peptides are septic mediators. Similar formyl peptides exist in mitochondria but little is known about their actions on human neutrophils (PMN). ⋯ Formylated mitochondrial proteins are potent immune activators. Acting through the FPR-1 receptor on professional phagocytes, MDP elicits [Ca]i release responses and Ca entry via G-protein-coupled pathways. MDP activates chemotaxis and respiratory burst. Our findings suggest a novel paradigm wherein one root cause of SIRS after trauma may be the release of mitochondrial fragments from mechanically damaged tissues. In this paradigm, mitochondrial debris "alarmins" alter host PMN phenotype, activating or suppressing immunity, predisposing to SIRS, sepsis or organ failure.
