Use of resuscitative balloon occlusion of the aorta in a swine model of prolonged cardiac arrest.

ABSTRACT:

Aim

We examined the use of a Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) catheter during cardiopulmonary resuscitation (CPR) after cardiac arrest (CA) to assess its effect on haemodynamics such as coronary perfusion pressure (CPP), common carotid artery blood flow (CCA-flow) and end-tidal CO₂ (PetCO₂) which are associated with increased return of spontaneous circulation (ROSC).

Methods

Six male swine were instrumented to measure CPP, CCA-Flow, and PetCO₂. A 7Fr REBOA was advanced into zone-1 of the aorta through the femoral artery. Ventricular fibrillation was induced and untreated for 8 min. CPR (manual then mechanical) was initiated for 24 min. Continuous infusion of adrenaline (epinephrine) was started at minute-4 of
