Induced Hypothermia Preserves the Functional Enterocyte Mass in A Porcine Multiple Trauma Model.
Multiple organ dysfunction syndrome (MODS) and the resulting multiple organ failure (MOF) following severe trauma are associated with increased morbidity and mortality. Due to intestinal mucosal lesions and gut barrier disorders, the intestine contributes decisively to how post-traumatic MOF develops. As mild therapeutic hypothermia has been found to have protective effects on post-traumatic organ injuries, we analysed its effects on the intestine. ⋯ Level III; therapeutic study.

Pneumonia is the most common complication observed in patients with severe injuries. Although the average age of injured patients is 47 years, existing studies of the effect of injury on the susceptibility to infectious complications have focused on young animals, equivalent to a late adolescent human. We hypothesized that mature adult animals are more susceptible to infection after injury than younger counterparts. ⋯ However, mature mice subjected to polytrauma demonstrated an exaggerated circulating inflammatory cytokine response to subsequent Pseudomonas pneumonia. Additionally, whereas prior injury increases LPS-stimulated IL-6 production by peripheral blood leukocytes from young (8-10-week-old) mice, injury does not prime IL-6 production by cell from mature adult mice. We conclude that in mature mice polytrauma results in increased susceptibility to Pseudomonas pneumonia while priming an exaggerated but ineffective inflammatory response.

Early trauma-induced coagulopathy may increase susceptibility to nosocomial infections such as ventilator-associated pneumonia. However, the relationship between trauma- induced coagulopathy and the development of ventilator-associated pneumonia in spinal cord injury patients has not been evaluated. ⋯ Coagulopathy on admission in patients with spinal cord injury is associated with a statistically significant increase in ventilator-associated pneumonia incidence. Additional research is warranted to further characterize this association.

Timing of septic shock onset may play a prognostic role in severe sepsis; however, clinical evidence provides contradictory results. This study aimed to investigate possible associations between timing of onset of septic shock and patient outcome. ⋯ This study showed the significance of timing of septic shock onset in prognosis among ICU patients with severe sepsis. Timing of shock onset further stratified patients with similar disease severity into different mortality risk groups. These findings deliver useful information regarding risk stratification of septic patients.
