Balloon technique may help improve circulation to heart and brain during cardiac arrest
Research Highlights: In a small feasibility study of 39 patients in England, physician responders used a minimally invasive procedure called Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) to try to improve blood flow to the heart and brain during out-of-hospital cardiac arrest. Several key measures of circulation improved during resuscitation: the lower blood pressure number (which is particularly important for restarting the heart during CPR) increased 62%, the upper number (an important determinant of blood flow to the brain) rose 20%, and carbon dioxide in exhaled breath, an important sign of effective circulation during CPR, increased 50%. The technique is currently used in trauma centers to treat life-threatening internal bleeding and is now being explored as a potential way to improve outcomes after out-of-hospital cardiac arrest by prehospital professionals. Researchers said if future research shows that the technique can be delivered to patients earlier and on a wider scale, potentially by training advanced critical care paramedics, it could increase the chances of restarting the heart and ultimately save more lives.
