Tranexamic acid (TXA) has been shown to reduce mortality in the treatment of traumatic hemorrhage. This effect seems most profound when given early after injury. We hypothesized that extending a protocol for TXA administration into the prehospital aeromedical setting would improve outcomes while maintaining a similar safety profile to TXA dosed in the emergency department (ED). ⋯ Prehospital administration of TXA during aeromedical transport did not improve survival compared with ED administration. Treatment with TXA was associated with increased risk of venous thromboembolic events. Prehospital TXA protocols should be refined to identify patients with severe hemorrhagic shock or traumatic brain injury.

The Congenital Diaphragmatic Hernia Study Group (CDHSG) registry is a multi-institutional tool to track outcomes of patients with CDH. The CDHSG asks surgeons to categorize diaphragmatic defect sizes as type A-D based on published guidelines. The reported size of the defect has been correlated with patient outcomes, but the reliability of this system has never been studied. Our goal was to evaluate the inter- and intra-rater reliability of the CDHSG grading system. ⋯ The demonstrated weak inter-rater reliability of the current CDHSG grading system shows the need for improvement in how the grading system is applied by surgeons when reporting CDH defect size.

Traditionally, all-terrain vehicles (ATVs) and dirt bikes (DBs) have been used in rural locations for recreation and work. Recently, there has been an increase in the use of these vehicles in an urban environment. The aim of this study is to compare the injury patterns of patients involved in crashes while riding off-road vehicles in both urban (UORV) and rural (RORV) environment. ⋯ Our data suggest that UORV use was associated with decreased helmet use, higher mean Injury Severity Score, lower presenting Glasgow Coma Scale, an increased need for emergent trauma bay procedures, higher unhelmeted Abbreviated Injury Scale head scores, and higher rates of extremity injuries.

A complex inflammatory response mediates the systemic effects of burn shock. Disruption of the endothelial glycocalyx causes shedding of structural glycoproteins, primarily syndecan-1 (SDC-1), leading to endothelial dysfunction. These effects may be mitigated by resuscitative interventions. ⋯ Addition of FFP, not of albumin, to post-burn resuscitation diminishes vascular leakage associated with large burns. Addition of colloid does not affect SDC-1 shedding as measured in plasma. Ongoing work will further define pathophysiologic mechanisms and potential therapeutic interventions to mitigate injury and promote repair of the endothelial glycocalyx.

Training for ultrasound-guided central venous catheterization (CVC) is typically conducted on static manikin simulators with real-time feedback from a skilled observer. Dynamic haptic robotic trainers (DHRTs) are an alternative method that simulates various patient anatomies and provides consistent feedback for each insertion. This study evaluates CVC needle insertion efficiency and skill gains of both methods. ⋯ No significant group differences were observed in overall skill gains, but residents' average procedural completion time decreased significantly from pretests to posttest. Overall results support DHRT as an effective method for training IJ CVC skills.
