Ranger O Low Titer (ROLO): Whole Blood Transfusion for Forward Deployed Units

ABSTRACT First-time use of Ranger O Low Titer (ROLO) blood and implementation of a forward-walking blood bank using predetermined donors proved essential in the survival of a 33-year-old active duty soldier following a complex blast injury during combat operations. The patient sustained significant bone, soft tissue, and vascular damage and continued to deteriorate despite resuscitation with cold-stored whole blood (WB). Only after utilizing the ROLO battle drill and transfusing with fresh WB was the patient able to be stabilized and evacuated. In this case report, we discuss how ROLO walking blood bank takes the next step in aiding resuscitation, providing smaller, forward-deployed units with blood resupply without the administrative burden of storage, particularly in resource-scarce environments. We provide an overview of WB and contrast its use to that of component therapy. In conjunction with the Golden Hour, ROLO can be incorporated as the standard damage control resuscitation to reduce the risks of noncompressible hemorrhage. By taking precautionary steps in the pre-deployment setting, ROLO offers an invaluable alternative to conventional resuscitation.

Balloons on the battlefield: REBOA implementation in the UK Defence Medical Services

Established in 2018, the Defence Endovascular Resuscitation (DefER) group recognised that resuscitative endovascular balloon occlusion of the aorta (REBOA) offered an option to improve survival in battle casualties dying from haemorrhage, particularly in remote and austere surgical settings. Following a successful jHub opportunity assessment, DefER purchased training and operational kit at pace. By 1 April 2019, the first forward surgical group undertook a bespoke endovascular training and assessment package. Results of the pilot were presented back to a jHub 4* Innovation Board, which initially awarded £500 000 to fund the project to full implementation. Med Op Cap provided a solution to establish REBOA as a core capability on to the 370 modules. REBOA catheters and arterial access kit are now available to deployed Role 2 facilities across defence as an adjunct to damage control resuscitation in specific circumstances. REBOA has, from a standing start, gained pan-Defence Medical Services (DMS) endorsement and has been integrated into deployed damage control resuscitation. To establish a new resuscitation capability across all Role 2 platforms within 15 months of inception represents implementation at pace. This agility was unlocked by empowering clinicians to develop the platform in conjunction with commercial procurement. This article describes how this innovative pathway facilitated the rapid introduction of a lifesaving haemorrhage control technique to equip DMS clinicians.

Successful limb salvage beyond the golden time following blunt traumatic open complete transection of the femoral artery and vein in a patient with cardiac arrest: a case report

Background Open complete transection of the femoral artery and vein following blunt trauma is extremely rare. Furthermore, even if the patient has been successfully resuscitated, it is sometimes difficult in most patients to preserve the injured limb, especially after damage control resuscitation. We report a case of open complete transection of the femoral artery and vein secondary to high-energy blunt trauma and a successful limb preservation treatment strategy. Case presentation A 57-year-old Asian man was transferred to hospital after having fallen from the 15th floor of a condominium. The patient was in cardiac arrest at the scene, but was successfully resuscitated by emergency medical services staff. On arrival, the patient’s hemodynamics were completely collapsed with active external bleeding from the thigh, so we immediately started resuscitation including activation of massive transfusion protocol and temporarily ligated the transected proximal superficial femoral artery, deep femoral artery just distal after branching lateral femoral circumflex artery and the superficial femoral vein. Following radiological findings showing a potential pelvic fracture with active bleeding, we also performed retroperitoneal packing in the resuscitation room and moved the patient to the angiography room for transcatheter arterial embolization. The patient’s consciousness was preserved and perfusion of the injured limb was barely maintained after his hemodynamics were adequately stabilized. As we detected weak perfusion of the lower limb via a potential collateral flow from the lateral femoral circumflex artery branches from deep femoral artery by pulse doppler of the dorsal pedis artery, we decided to reconstruct superficial femoral artery and vein at 24 h after injury using great saphenous vein bypass grafts. The patient was transferred to a rehabilitation hospital with good neurological and limb outcome after hospitalization for 52 days. Conclusion We successfully preserved the patient’s lower limb after cardiac arrest and complete transection of the femoral artery and vein and achieved a good neurological outcome. Even if a femoral artery needs to be ligated temporarily, careful observation and assessment should be performed so as not to lose the chance to salvage the limb even during damage control resuscitation.

Resusitasi Pengendalian Kerusakan Di Unit Perawatan Intensif

Abstrak Resusitasi dengan pengendalian kerusakanmenggambarkan suatu pendekatan ke perawatan awal pada pasien dengan cedera berat. Tujuan pendekatan ini untuk menjaga pasien tetap stabil dengan menghindari intervensi dan kondisi yang berisiko kepada keadaan perburukan dengan mengendalikan trias kematian, yaitu hipotermia, koagulopati, dan asidosis. Merupakan hal yang penting bahwa konsep dan kepraktisan pendekatan ini dipahami oleh semua yang terlibat dalam manajemen awal pasien trauma. Pendekatan ini dimulai dengan pemberian produk darah sejak awal, penghentian perdarahan dan pengembalian volume darah yang bertujuan untuk mengembalikan stabilitas fisiologis dengan cepat. Resusitasi dengan pengendalian kerusakan memilikibeberapa tambahan pendekatan dari bidang farmakologis dan laboratorium untuk meningkatkan perawatan pasien yang mengalami perdarahan. Pendekatan ini termasuk trombelastografi sebagai ukuran rinci kaskade pembekuan, asam traneksamat sebagai antifibrinolitik. Kata kunci : hipotermia, koagulopati, asidosis, perdarahan masif Damage Control Resuscitation in Intensive Care Unit Abstract Damage control resuscitation (DCR) describes an approach to the early care of very seriously injured patients. The aim is to keep the patient alive whilst avoiding interventions and situations that risk worsening their situation by driving the lethal triad of hypothermia, coagulopathy and acidosis.It is critical that the concepts and practicalities of this approach are understood by all those involved in the early management of trauma patients. Damage control resuscitation forms part of an overall approach to patient care rather than a specific intervention and has evolved from damage control surgery. It is characterised by early blood product administration, haemorrhage arrest and restoration of blood volume aiming to rapidly restore physiologic stability. The infusion of large volumes of crystalloid is no longer appropriate, instead the aim is to replace lost blood and avoid dilution and coagulopathy. In specific situations, permissive hypotension may also be of benefit, particularly in patients with severe haemorrhage from an arterial source. Damage control resuscitation has been augmented by both pharmacologic and laboratory adjuncts to improve the care of the hemorrhaging patient. These include thrombelastography as a detailed measure of the clotting cascade, tranexamic acid as an antifibrinolytic. Keywords: hypothermia, coagulopathy, acidosis, massive bleeding
