RESUMO
BACKGROUND: Extremity tourniquets have proven to be lifesaving in both civilian and military settings and should continue to be used by first responders for trauma patients with life-threatening extremity bleeding. This is especially true in combat scenarios in which both the casualty and the first responder may be confronted by the imminent threat of death from hostile fire as the extremity hemorrhage is being treated. Not every extremity wound, however, needs a tourniquet. One of the most important aspects of controlling life-threatening extremity bleeding with tourniquets is to recognize what magnitude of bleeding requires this intervention and what magnitude of bleeding does not. Multiple studies, both military and civilian, have shown that tourniquets are often applied when they are not medically indicated. Overuse of extremity tourniquets has not caused excess morbidity in either the recent conflicts in Iraq and Afghanistan or in the US urban civilian setting. In the presence of prolonged evacuation, however, applying a tourniquet when it is not medically indicated changes tourniquet application from being a lifesaving intervention to one that may cause an avoidable amputation and the development of an array of metabolic derangements and acute kidney injury collectively called prolonged tourniquet application syndrome. METHODS: The recent literature was reviewed for papers that documented the complications of tourniquet use resulting from the prolonged casualty evacuation times being seen in the current Russo-Ukrainian war. The literature was also reviewed for the incidence of tourniquet application that was found to not be medically indicated, in both the US civilian setting and from Ukraine. Finally, an in-person meeting of the US/Ukraine Tourniquet Working Group was held in Warsaw, Poland, in December of 2023. RESULTS: Unnecessary loss of extremities and life-threatening episodes of prolonged tourniquet application syndrome are currently occurring in Ukrainian combat forces because of nonindicated tourniquet use combined with the prolonged evacuation time seen in the Russo-Ukrainian war. Specific numbers of the complications experienced as a result of tourniquet use by Ukrainian forces in the current conflict are treated as classified information and are not available, but multiple sources from the Ukrainian military medical personnel and from the US advisors providing medical assistance to Ukraine have all agreed that the problem is substantial. CONCLUSION: Unnecessary tourniquet morbidity might also occur in US forces in a variety of potential future combat scenarios in which evacuation to surgical care is delayed. Prehospital trauma training programs, including but not limited to tactical combat casualty care, place insufficient emphasis on the need to avoid leaving tourniquets in place when they are not medically indicated. This aspect of training should receive emphasis in future Tactical Combat Casualty Care (TCCC) and civilian first responder curriculum development. An interim ad hoc training solution on this topic is available at the websites noted in this articles. Additional training modalities may follow in the near future. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level V.
RESUMO
The combat penetrating gunshot injury is frequently associated with damage to the liver. Bile leak and external biliary fistula (EBF) are common complications. Biliary decompression is commonly applied for the management of EBF. Also, little is known about the features of combat trauma and its management in ongoing hybrid warfare in East Ukraine. A 23-year-old male was diagnosed with thoracoabdominal penetrating gunshot wound (GSW) by a high-energy multiple metal projectile. Damage control tactics were applied at all four levels of military medical care. Biliary decompression was achieved by endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (EST) and the placement of biliary stents. Occlusion of the stent was treated by stent replacement, and scheduled ERCP was performed. Partial EBF was diagnosed from the main wound defect of the liver and closed without surgical interventions on the 34th day after the injury. A combination of operative and nonoperative techniques for the management of the combat GSW to the liver is effective along with the application of damage control tactics. A scheduled ERCP application is an effective approach for the management of EBF, and liver resection could be avoided. A successful biliary decompression was achieved by the transpapillary intervention with the installation of stents. Stent occlusion could be diagnosed in the early post-traumatic period, which is effectively managed by scheduled ERCP as well as stent replacement with a large diameter as close as possible to the place of bile leak.
