The battle along Antietam Creek in September 1862 was pivotal in shaping future combat medical readiness practices. With the full confidence of his commander, Major (Dr) Jonathan Letterman implemented an innovative ambulance corps system, which contributed immensely to modern-day battlefield medicine. Each year, the Uniformed Services University (USU) holds the Antietam Staff Walk, during which military medical students are engaged by faculty at various "stops" along the 6-mile walk. The four learning objectives for the Antietam Staff Walk are to (1) introduce the role of the "staff ride," (2) orient learners to reading terrain, (3) reinforce the six principles of health service support, and (4) recall the heritage of the military medical officer. The Department of Military and Emergency Medicine at USU commissioned a program evaluation to determine if these course objectives were being met, evaluate the effectiveness of the Antietam Staff Walk as a teaching tool, and make recommendations for improving its educational impact. ⋯ Our review of the Antietam Staff Ride resulted in several curricular recommendations for enhancing its learning impact. Our program evaluation serves as a model for line units and other military organizations to optimize the impact of the historical staff ride as a teaching tool.

Extracorporeal cardiopulmonary resuscitation (ECPR) in patients with prolonged or refractory out-of-hospital cardiac arrest (OHCA) is likely to be beneficial when used as part of a well developed emergency service system. ECPR is technically challenging to initiate and resource-intensive, but it has been found to be cost-effective in hospital-based ECPR programs. ⋯ The efficacy, scalability, sustainability and cost-effectiveness of these programs need to be assessed. There is a need for national collaboration to determine the most cost-effective delivery strategies for ECPR provision along with its place in the OHCA survival chain.

To determine the effect of video and direct laryngoscopy on first-pass success rates for out-of-hospital orotracheal intubation. ⋯ We found substantial heterogeneity among out-of-hospital studies comparing video laryngoscopy to direct laryngoscopy on first-pass success, overall success, or intubation time. This heterogeneity was not explained with stratification by study design, clinician type, video laryngoscope blade geometry, or leave-one-out meta-analysis. A majority of studies showed that video laryngoscopy was associated with improved first pass success in all subgroups, but only for paramedics and not physicians when looking at overall success. This improvement was more common in studies that used Macintosh blades than those that used hyperangulated blades. Future research should explore the heterogeneity identified in our analysis with an emphasis on differences in training, clinical milieu, and specific video laryngoscope devices.

Early recognition of traumatic brain injury (TBI) is important to facilitate time-sensitive care. Electroencephalography (EEG) can identify TBI, but feasibility of EEG has not been evaluated in prehospital settings. We tested the feasibility of obtaining single-channel EEG during air medical transport after trauma. We measured association between quantitative EEG features, early blood biomarkers, and abnormalities on head computerized tomography (CT). ⋯ Prehospital EEG acquisition is feasible during air transport after trauma.

The concept of early administration of P2Y12 inhibitor in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) is widely accepted, but whether prehospital administration results in greater coronary reperfusion remains unclear. Our study aims to analyze the benefit and safety of prehospital P2Y12 inhibitor compared to in-hospital P2Y12 inhibitor administration. ⋯ Prehospital P2Y12 inhibitor compared to in-hospital P2Y12 inhibitor is associated with a significantly higher rate of pre-PCI and post-PCI TIMI flow grade 2-3, a reduced risk of recurrent MI, and no increase in major bleeding in STEMI patients undergoing primary PCI.
