Resuscitative endovascular balloon occlusion of the aorta in a pediatric swine model: Is 60 minutes too long?

Pediatric swine study comparing 30-minute versus 60-minute zone 1 REBOA after controlled hemorrhage found that 30-minute occlusion effects resolved during critical care, while 60-minute occlusion caused persistent metabolic acidosis and organ injury. Findings suggest 60 minutes of aortic occlusion may exceed safe limits in pediatric patients.
