[Resuscitative Endovascular Balloon Occlusion of the Aorta: Implementation and Nursing Care]

Uncontrolled hemorrhagic shock is the main cause of death in patients with traumatic injuries. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a rapidly performed and less-invasive treatment to stop bleeding. The REBOA balloon may be placed at the location of bleeding to achieve hemostasis. Prior to balloon placement, the indications for placement must be evaluated, including non-thoracic aortic trauma and non-traumatic patients with postpartum hemorrhage, and the appropriate sheath size (from 5 to 8 French) must be selected based on the bleeding site. As vascular injury of aortic dissection, rupture, or perforation may occur during the procedure, changes in hemodynamic parameters should be monitored. After balloon placement, ischemic complications due to blood flow occlusion such as lower extremity ischemia and acute renal failure should be tracked. After balloon removal, reperfusion injuries may occur, which can result in multiple organ failure, and should be observed closely. When caring for patients receiving REBOA, physicians should explain the procedure to their families to obtain informed consent. Also, nurses should prepare supplies and closely monitor changes in critical life signs to minimize the risks of hypotension, arrhythmia, and changes in consciousness during the procedure. After placement, the neurovascular and peripheral limbs "5P" (pain, pallor, paresthesia, pulselessness and paralysis) condition should be evaluated and recorded in detail. This treatment approach requires further study and research to assess the long-term impacts of placement and improve quality of care in these patients.
