Background Whole blood therapy—which contains the ideal balance of components, and particularly fresh whole blood—has been shown to be beneficial in adult trauma. It remains unclear whether there is potential benefit in the pediatric population. Study Design and Methods This is a secondary analysis of previously published data analyzing pediatric casualties undergoing massive transfusion in the Department of Defense Trauma Registry. Pediatric patients with traumatic injury who were transfused at least one blood product were included in the analysis. We compared children who received component therapy exclusively to those who received any amount of warm fresh whole blood. Results Of the 3439 pediatric casualties within our dataset, 1244 were transfused at least one blood product within the first 24 h. There were 848 patients without severe head injury. Within this cohort, 23 children received warm fresh whole blood overall, 20 of whom did not have severe head injury. In an adjusted analysis, the odds ratio (95% confidence interval [CI]) for survival for warm fresh whole blood recipients was 2.86 (0.40–20.45). After removing children with severe brain injury, there was an independent association with improved survival for warm fresh whole blood recipients with an odds ratio (95% CI) of 58.63 (2.70–1272.67). Discussion Our data suggest that warm fresh whole blood may be associated with improved survival in children without severe head injury. Larger prospective studies are needed to assess the efficacy and safety of whole blood in children with severe traumatic bleeding.

Introduction Role 1 care is vital to patient survival and includes many echelons of care from point-of-injury first aid to medical attention at battalion aid stations. Many guidelines are written for Role 1 care providers to optimize care for different scenarios. Differences in the guidelines lead to confusion and discrepancies between the types of treatment medical care providers provide. Although the guidelines were written for different areas of care, uniformity between the guidelines is needed and will lead to a reduced mortality rate. Materials and Methods It was determined that the Tactical Combat Casualty Care Guidelines, Prolonged Field Care Guidelines, Joint Trauma System Clinical Practice Guidelines, and Standard Medical Operating Guidelines from medical evacuation were the military medical guidelines most relevant to Role 1 care. These Guidelines were compared side by side to determine the differences between them. Results Although the guidelines were largely similar, many major differences were found between them. Our online tables contain large inconsistences between guidelines including direct contradictions in conversion of junctional tourniquets and the administration of tranexamic acid. Conclusions Role 1 care is vital to patient survival, including care from point of injury to battalion aid stations, but the guidelines available to instruct this care and the guidance on which personnel should provide this care are conflicting. This lack of clarity and consistency may adversely impact treatment outcomes. The reduction or elimination of conflicting information across the various guidelines, augmentation of guidance for pediatric care, more specific guidance for unique levels of care, and clearer delineation of the Role 1 phases of care (as well as which guidelines are most appropriate to each) should be considered as urgent priorities within the military medical community.

Introduction: Airway injuries are the second leading cause of potentially survivable battlefield death and often require airway management strategies. Airway suction, the act of using negative pressure in a patient’s upper airway, removes debris that can prevent respiration, decreases possible aspiration risks, and allows clearer viewing of the airway for intubation. The most important characteristics for a portable airway suction device for prehospital combat care are portability, strong suction, and ease of use. Methods: This market review searched academic papers, military publications, Google searches, and Amazon to identify devices. The search included specific characteristics that would increase the likelihood that the devices would be suitable for battlefield use including weight, size, battery life, noise emission, canister size, tubing, and suction power. Results: Sixty portable airway suction devices were resulted, 31 of which met inclusion criteria – 11 manually powered devices and 20 battery-operated devices. One type of manual suction pump was a bag-like design with a squeezable suction pump that was extremely lightweight but had limited suction capabilities (vacuum pressure of 100mmHg). Another type of manual suction pump had a trigger-like design which is pulled back to create suction with a firm collection canister that had increased suction capabilities (vacuum pressures of 188-600mmHg), though still less than the battery operated, and was slightly heavier (0.23-0.458kg). Battery-operated devices had increased suction capabilities and were easier to use, but they were larger and weighed more (1.18-11.0kg). Conclusion: Future research should work to lighten and debulk battery-operated suction devices with high suction performance.
