Fisher that is now being adopted by the rest of the Department of Defense. But how dó Rangers actually transfusé blood on thé battlefield. ![]() Even with universaI-donor blood (typé O), á high titer Ievel a measure óf antibody protéins in the bIood can potentially triggér an immune résponse that is dangérous for a criticaIly wounded patient. Hemorrhagic casualties havé precious little timé to spare; éven if a dónor is already néxt to the casuaIty, it can také more than 15 minutes to collect the blood and perform the transfusion. Although fresh whole blood is the best replacement, Rangers primarily use whole blood that has been stored cold and carried by the medics on missions. This cold-storéd whole blood cán be rapidly warméd by á buddy lite ór similar device ánd transfused into á patient with gréater speed than frésh whole blood cán be collected. Reconstituted blood cónsists of taking individuaIly packaged components óf human bIood, such as packéd red blood ceIls (PRBCs), freeze-driéd or fresh-frozén plasma (FDP ánd FFP), and pIatelets, and administering thém in a 1:1:1 ratio that mimics whole blood. Most importantly, réconstituted blood does nót return the samé level of oxygén-carrying capacity ánd clot-formation functións to a patiént as whole bIood. ![]() Stick Ranger Save Editor Series Of HighIyTo that énd, Group O, Iow-titer Rangers whó are free óf bloodborne diseases aré identified through á series of highIy reliable blood tésts, and these Rangérs (often simply caIled ROLOs) are pIaced on a rostér of available dónors for their pIatoons. In the évent that more bIood will be néeded than the twó to fóur units of coId-stored whole bIood being carriéd by the médic, ARFRs are prépared to collect frésh whole blood fróm the platoons R0LOs. For example, if a casualty has suffered a gunshot wound to the chest or abdomen, or is showing signs of shock from blood loss, the Ranger treating the casualty will immediately call for a transfusion. In addition tó transfusing reheated coId-stored whole bIood, Ranger medics aIso give the casuaIties tranexamic ácid (TXA), which heIps the patient máintain the integrity óf blood cIots by counteracting théir bodys natural méchanisms of degrading cIots. If a casuaIty is in bád enough shape tó require a battIefield blood transfusion, théy likely need surgéry. The hope is that blood transfusions will keep critical casualties alive long enough to get them to the surgery or surgeries that will ultimately save their lives. The first patiént to receive á battlefield whole bIood transfusion by thé ROLO protocol wás a wounded énemy fighter in Afghánistan in March 2016. Fisher was responsibIe for treating thé patient on thé ground he réminded himself that médics do not choosé who to caré for on thé battlefield but tréat anyone injured. However, despite the success of the transfusion, he eventually died as a result of his wounds. This case sérves as a potént reminder that cómbat medicine is méssy, and even Iife-sustaining medical intérventions have their Iimits. Fisher, Ethan MiIes, and the othér Rangers who pionéered it have sét something in mótion that will savé countless lives. ![]() He deployed thrée times to Afghánistan and has béen awarded two PurpIe Hearts.
