Best of 2025 — Episode 2: Pediatric Trauma and the Life-Saving Window for Prehospital TXA

In this episode, Dr. Kimmo Murto and Dr. Jeannie Callum examine the leading causes of death in pediatric trauma, with a focused discussion on early hemorrhagic mortality and the downstream impact of traumatic brain injury. The conversation explores why children are uniquely vulnerable after severe trauma, emphasizing the first six hours following injury—a critical window when uncontrolled hemorrhage is most likely to be fatal and when early intervention can meaningfully alter outcomes. Key anatomical and physiological differences between children and adults are unpacked, highlighting how these factors influence bleeding, shock recognition, and rapid clinical deterioration in the prehospital phase. A central theme of the episode is the role of prehospital tranexamic acid (TXA). The discussion addresses both the science and the system-level realities of TXA use in pediatric trauma, including timing, mechanisms of action, and barriers to early administration. Featured Clips in This Episode Clip 1 — The Nuances of Pediatric Trauma Dr. Murto explores the unique complexities of pediatric trauma care, including how children compensate differently than adults, why hemorrhage can be deceptively difficult to recognize, and how these nuances demand a tailored, physiology-informed approach in the prehospital setting. Clip 2 — TXA Through a Prehospital Lens Dr. Callum discusses TXA from a prehospital and trauma-system perspective, focusing on why earlier administration delivers the greatest survival benefit, how delays erode effectiveness, and what prehospital teams can realistically control to move TXA closer to the point of injury. The episode concludes with a clear call to action: aligning prehospital practice, education, and trauma system design around early hemorrhage control and timely TXA administration to improve survival and neurological outcomes for injured children.
