- Medicine
Step into the vanguard of battlefield medicine with Dr. John M. Croushorn, an engineer-turned-emergency physician whose innovations are redefining trauma treatment. From his pivotal career switch of joining Army Medicine post-9/11 to creating the Abdominal Aortic Junctional Tourniquet (AAJT-S), this episode weaves together the personal and the technical, providing an intimate look at the challenges and triumphs of military medicine.
As we converse with Dr. Croushorn, you'll be transported to the front lines of tactical emergency medical solutions, where the origins of such practices in the military and law enforcement laid the groundwork for today's life-saving techniques. Discover the birth of the AAJT-S, spurred by tragedy and necessity, and how a chance encounter with a Special Forces Medic brought the device's development full circle. This narrative captures the essence of innovation — where creativity meets critical needs, and every step in the design process can mean the difference between life and death. The trenches of tactical medicine are filled with stories of lives saved and legacies forged, and each tale tightens the bond between trauma care advancements and those who stand ready at the front lines.
Dr. Croushorn continues to pull back the curtain on the dynamic field of military medicine, guiding us through the application of junctional tourniquets and their profound impact on saving lives in pre-hospital scenarios. We'll also cast an eye to the future, examining ongoing research and the global implications of these medical advancements. Hear tales of the AAJT-S's deployment in diverse environments, from the deserts of the Middle East to the conflict in Ukraine, and learn how this technology is not just a tool but a testament to human resilience and the relentless pursuit of advancing trauma treatment.

(15:08) Developing Tactical Emergency Medical Solutions
Tactical medicine's role in the FBI, development of the AAJT-S for pelvic bleeding, and a serendipitous encounter with a Special Forces Medic.
(21:26) Junctional Tourniquets for Hemorrhage Control
Junctional tourniquets are crucial in trauma care, effectively controlling hemorrhage in extremity-torso junctions and surpassing other methods.
(35:19) Junctional Tourniquet Application and Future Innovations
Versatile junctional tourniquet device for pediatric to 64-inch circumference patients, efficacy compared to REBOA, and use in trauma centers and NCTH.
(45:38) Physiologic Effects of a Cardiac Device
Innovative application of the AAJT-S has shown impressive results in traumatic cardiac arrest scenarios, leading to protocol changes and ongoing studies in Ukraine.
Take Home Messages:
The tragic events of 9/11 inspired a shift in career from electrical engineering to Military Medicine, highlighting the profound impact significant historical events can have on individual life choices.
The development of the Abdominal Aortic Junctional Tourniquet (AAJT-S) marked a significant advancement in pre-hospital trauma care, particularly for severe hemorrhage control in areas where traditional tourniquets are ineffective.
Innovation in military medical devices can stem from unexpected places, including the adaptation of materials like bike shop inner tubes, demonstrating resourcefulness in the face of challenges.
Collaboration between medical professionals and those with hands-on battlefield experience, such as Special Forces Med
