The geography of Norway has led to an initiative to train teams from rural hospitals in damage control surgery using a team-oriented approach based on Crew Resource Management. Our aim was to evaluate this approach and its impact on trauma care in rural hospitals across Norway. ⋯ Teaching damage control surgery using a team-oriented approach is an innovative educational method for rural hospitals.

Most prehospital medical interventions during civilian and military trauma casualty transport fail to utilize advanced decision-support systems for treatment and delivery of medical interventions, particularly intravenous fluids and oxygen. Current treatment protocols are usually based on standard vital signs (eg, blood pressure, arterial oxygen saturation) which have proven to be of limited value in detecting the need to implement an intervention before cardiovascular collapse. A primary objective of the US Army combat casualty care research program is to reduce mortality and morbidity during casualty transport from the battlefield through advanced development of a semiautomated decision-support capability for closed-loop resuscitation and oxygen delivery. ⋯ We propose that derived indices based on currently available technology for continuous monitoring of specific hemodynamic, autonomic, and/or metabolic responses could provide earlier recognition of hemorrhage than current standard vital signs and allow intervention before the onset of circulatory shock. Because of this, such indices could provide improved feedback for closed-loop control of patient resuscitation and oxygen delivery. These technological advances could prove instrumental in advancing decision-support capabilities for prehospital trauma care during transport to higher levels of care in both the military and civilian environments.

Toll-like receptors (TLR) 2 and TLR4 expressed on innate immune cells are important mediators of the immune response to pathogens. In this study, we hypothesized that burn injury results in altered cytokine secretion profiles after TLR2 or TLR4 ligation that is associated with altered TLR expression on innate immune cells. ⋯ Cytokine secretion profiles after TLR2 and TLR4 ligation after burn injury are altered in a manner not clearly reflective of an anti-inflammatory or proinflammatory state and are associated with unique changes in the macrophage population. TLR2 and TLR4 ligation have complex and varied roles in mediating the immune response to burn injury.
