Abstract

Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is an endovascular procedure which utilises a catheter based balloon device to achieve aortic occlusion. The aim of this resuscitative measure is to improve blood pressure proximal to the occlusion site and therefore preserve cardiac and cerebral perfusion in order to prevent cardiac arrest; additionally there is a relative reduction in arterial inflow to the site of injury. Endovascular techniques are gaining acceptance for the in-hospital management of haemorrhage, however their use in pre-hospital care is still limited. This is due to a number of factors including the technical challenges, training and skill sets of pre-hospital care teams and the potential for harm of REBOA, particularly with extended balloon occlusion times. However, non compressible torso haemorrhage is associated with a mortality of approximately 50% and a significant proportion of these deaths  occur in the pre-hospital phase of care. In the exsanguinating patient, resuscitative thoracotomy (RT) with direct aortic compression is often the only means to control haemorrhage. This resuscitative measure is now an established pre-hospital intervention which has significantly improved outcomes in the context of penetrating trauma, particularly thoracic injury. In the context of blunt injury and subdiaphragmatic haemorrhage, however, the outcomes from pre-hospital resuscitative thoracotomy remain poor. We present our initial technique for successfully introducing REBOA for the pre-hospital management of exsanguinating pelvic or groin heamorrhage following trauma, our indications for REBOA and comment on the problems and limitations encountered as well the lessons learned.
