The Louisiana Emergency Response Network (LERN), a statewide trauma system, has a single communication center with real-time data on hospital capacity across the state. With these data, scene information, and a standardized triage protocol, prehospital providers are directed to the most appropriate hospital. The purpose of our study was to compare outcomes between those patients who complied with the LERN communication center direction and those who did not. ⋯ Following direction from a central communication center with real-time hospital capacity data yielded a 6-fold decrease in secondary transfer and a 3-fold decrease in mortality. These data emphasize the value of an organized statewide trauma network that routes patients to the appropriate facilities.

Pseudomonas aeruginosa is a major cause of morbidity and mortality among burn patients, despite antibiotic therapy. There is a need to identify innate immune defenses that prevent P aeruginosa infection in injured adults in an effort to find therapeutic alternatives to antibiotics. Here, we tested our hypothesis that microvesicles (MVs) in bronchoalveolar (BAL) fluid have a role in the immunity of the lung in response to pathogens. ⋯ Using a preclinical model, BAL MVs are reduced after scald injury and BAL MV restoration to injured mice improves survival and bacterial clearance. The antimicrobial mechanisms leading to improved survival include the quantity and SPH content of BAL MVs.
