In this episode of Frontline Surgery: Mastering Military Trauma, hosts Dr. Joshua Dilday and Dr. Rachel Russo are joined by Dr. Frank Butler and Dr. John Holcomb, to examine one of the most consequential shifts in battlefield medicine: tourniquet reassessment and conversion in the era of prolonged evacuation. The episode traces the evolution of tourniquet use from its controversial origins in TCCC to the hard lessons now emerging from the Russo-Ukrainian war, where contested airspace, drone threats, and ground evacuation timelines of six hours or more have fundamentally changed the risk-benefit calculus of leaving a tourniquet on.

The panel is direct: up to 75% of tourniquets applied in the field are not medically necessary in hindsight, and with prolonged evacuation now the norm rather than the exception, unnecessary tourniquet time is costing limbs and lives. The message is not to stop using tourniquets but to use them smarter, reassess them as soon as tactically possible, convert them within two hours when feasible, and never remove them after six hours without surgical backup. Dr. Butler also previews a new plain-language training package designed for non-medical service members, built on the principle that the knowledge is only as good as the person holding the tourniquet.
