## Resource

In this episode of the Prolonged Field Care Podcast, Dennis sits down with trauma surgeon Mark Shapiro for a no-BS masterclass on wound ballistics. They break down why understanding the physics of penetrating and blast trauma matters in austere and combat environments — even when experience makes you cynical. From high-velocity rifle rounds and their massive temporary cavities to the infectious nightmare of shotgun wounds and the four phases of blast injury, Mark shares hard-won lessons from civilian Level I trauma centers and years training special operations medics and ground surgical teams. They tackle the myths around entry/exit wounds, when (and when not) to explore right upper quadrant gunshot wounds downrange, why you should almost never pack the abdomen or chest from the outside, how to assess neurovascular status in blast-injured extremities, and why bizarre bullet paths and “stable” patients with signs of life can still surprise you. Key Takeaways: Kinetic energy (½mv²) means velocity is king — high-velocity rifle rounds create devastating temporary cavities and fragmentation that can turn one projectile into many. Jacketed rounds still fragment at rifle speeds; never assume a clean through-and-through. Bone fragments act like secondary missiles and can create wounds up to 3x the size of the fragment. For stable patients with right upper quadrant GSWs in resource-limited settings, expectant management can be reasonable — but you must have a plan, know your limits, and be ready to move if things change. Never pack the abdomen or chest from the outside in most cases. It risks pushing debris deeper and worsening injuries. Cover exposed organs if needed, but don’t shove gauze into body cavities. Shotgun wounds (especially buckshot/birdshot) are “mobile IEDs” — ma…
