The Effect of Chest Compression Location and Occlusion of the Aorta in a Traumatic Arrest Model
Abstract
Background: Recent evidence has demonstrated that closed chest compressions directly over the left ventricle (LV) in a traumatic cardiopulmonary arrest (TCA) model improve hemodynamics and return of spontaneous circulation (ROSC) when compared to traditional chest compressions. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is also able to improve hemodynamics as well as control hemorrhage during TCA. We hypothesized that chest compressions located over the LV would result in improved hemodynamics and ROSC when compared to traditional compressions in a swine model of TCA using REBOA. Materials and Methods: Transthoracic echo was used to mark the location of the aortic root (Traditional location) and the center of the LV on animals (n=26) which were randomized to receive chest compressions in one of the two locations. After hemorrhage, ventricular fibrillation (VF) was induced to simulate TCA. After a period of ten minutes of VF, basic life support (BLS) with mechanical CPR was initiated and performed for ten minutes followed by advanced life support (ALS) for an additional ten minutes.
