US Troops Update Tourniquet Techniques Post-Ukraine War

The war in Ukraine influences US military medics’ tourniquet training, focusing on proper removal techniques to prevent limb loss.

As the US military adapts to the evolving demands of modern warfare, the training for special operations medics is undergoing significant changes, particularly in how they handle tourniquets. In light of lessons learned from the war in Ukraine, medics are being taught to not only apply tourniquets but also to remove them, a practice that was largely neglected during the Global War on Terror.

Current training protocols prescribe that tourniquets should be applied tight to control bleeding, but the removal was typically reserved for advanced medical personnel. However, the dynamics of contemporary combat, especially in large-scale operations where evacuation may be delayed, necessitate a shift in this approach.

Modern tourniquets are robust nylon straps, designed to be cinched around a wounded limb to halt blood flow. In previous conflicts, the immediate priority was to prevent soldiers from bleeding out while anticipating quick evacuations. However, the landscape of battlefields like Ukraine highlights the necessity for medics to manage prolonged tourniquet applications, emphasizing potential long-term damage that can result from their extended use.

According to the Army’s special operations medical course chief, soldiers in training must now demonstrate proficiency in removing tourniquets—a process termed “tourniquet conversions”—and are graded on their ability to teach these skills to others. “As we’re seeing more battlefield data from modern conflicts without that golden hour, medics are forced to make a decision themselves as to when and if they reverse that tourniquet,” the chief explained. “If you don’t, you lose that limb.”

Overall, hemorrhage remains the leading cause of preventable death on the battlefield, making the tourniquet an essential tool in a medic’s kit. However, the unique challenges posed by Ukraine’s combat environment—characterized by surveillance and drone use—have altered the once clear guidelines regarding tourniquet use. In this context, medics must manage casualties for longer periods, posing the risk of serious complications from leaving tourniquets on for extended durations.

One striking lesson from the Ukraine war is the need for more comprehensive training in tourniquet removal. Col. Ken Dwyer, head of the Army’s Special Warfare Center and School, highlighted that while the initial application of a tourniquet could save a life, it becomes crucial to consider less damaging methods for controlling bleeding as the situation progresses.

In the past, military medics trained primarily to apply a tourniquet, often overlooking the procedures for safely loosening the device—a practice rife with risks. Yet, in a war zone where ground evacuations are fraught with danger, and air support may be compromised, such skills are increasingly essential.

The complexity of care on modern battlefields demands that troops, irrespective of their specific roles, become adept in both applying and removing tourniquets. With the increasing difficulty of casualty evacuation—a scenario compounded by the dangers associated with deploying medical teams—this shift in training is not just a recommendation but a necessity.

As military experts reassess the fundamental assumptions regarding casualty management, the focus has shifted to ensuring that all personnel trained on tourniquets are equally prepared to take them off. This comprehensive understanding is crucial for preventing unnecessary complications and preserving the health of injured service members.

The ongoing developments in training protocols are reflective of a broader evolution in military medicine, driven by the harsh realities faced by troops in combat scenarios like that of Ukraine.
