Three Forward Aeromedical Evacuation platforms operate in Southern Afghanistan: UK Medical Emergency Response Team (MERT), US Air Force Expeditionary Rescue Squadron (PEDRO), and US Army Medical Evacuation Squadrons (DUSTOFF), each with a different clinical capability. Recent evidence suggests that retrieval by a platform with a greater clinical capability (MERT) is associated with improved mortality in critical patients when compared with platforms with less clinical capability (PEDRO and DUSTOFF). It is unclear whether this is due to en route resuscitation or the dispatch procedure. ⋯ This trend was continued only in the MERT group for the highest ISS bin (1.39 ± 0.62 vs. 1.09 ± 0.42; P = 0.001), whereas a deterioration was identified in the PEDRO group (0.88 ± 0.37 vs. 1.02 ± 0.43; P = 0.440). The use of a Forward Aeromedical Evacuation platform with a greater clinical capability is associated with an improved hemodynamic status in critical casualties. The ideal prehospital triage should endeavor to match patient need with clinical capability.

Trauma transfusion strategies, which incorporate balanced red-cell concentrate (RCC)-to-fresh frozen plasma (FFP) ratios, may be associated with improved survival in massively transfused patients. However, the use of this approach in nonmassively transfused patients has led to concern regarding an increase in acute respiratory distress syndrome (ARDS). The aim of this study was to assess the incidence of ARDS in transfused UK military casualties. ⋯ Of the remaining 80 massively transfused patients, 11 were in the low and 73 were in the high-ratio groups. There was no difference in the incidence of ARDS between low- and high-ratio groups in either nonmassively transfused (22.2% vs. 9.5%; P = 0.232) or massively transfused (18.2% vs. 23.3%; P = 1.000) casualties. There was no statistically significant increase in the incidence of ARDS in UK casualties treated with high, compared with low, ratios of plasma to RCC.
