Resuscitative Balloon Occlusion of the Aorta in Non-traumatic Out of Hospital Cardiac Arrest

The primary aim of this study is to investigate the feasibility and complications of inserting a REBOA-catheter to patients suffering from non-traumatic out-of-hospital cardiac arrest, by anesthesiologist working in the pre-hospital setting. The study will include patients in the catchment population of St. Olavs University Hospital, Trondheim area, Norway. The REBOA technique (resuscitative balloon occlusion of the aorta) is a well-known treatment used on other indications, both in-hospital and pre-hospital. It has also been utilized in several animal studies on non-traumatic cardiac arrest and has shown to augment myocardial and cerebral perfusion during cardio-pulmonary resuscitation. There are no systematic studies on humans with REBOA in non-traumatic cardiac arrest. The study will also investigate the time needed to perform a REBOA procedure in cardiac arrest patients receiving advanced cardiac life support. This additional treatment might contribute to increase the survival rate of cardiac arrest patients.
