To describe the current use of the ER-REBOA catheter and associated outcomes and complications.
Noncompressible truncal hemorrhage is the leading cause of potentially preventable death in trauma patients. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a novel strategy to obtain earlier temporary hemorrhage control, supporting cardiac, and cerebral perfusion before definitive hemostasis.
Prospective, observational study conducted at 6 Level 1 Trauma Centers over 12-months. Inclusion criteria were age >15 years of age with evidence of truncal hemorrhage below the diaphragm and decision for emergent hemorrhage control intervention within 60 minutes of arrival. REBOA details, demographics, mechanism of injury, complications, and outcomes were collected.
A total of 8166 patients were screened for enrollment. In 75, REBOA was utilized for temporary hemorrhage control. Blunt injury occurred in 80% with a median injury severity score (ISS) 34 (21, 43). Forty-seven REBOAs were placed in Zone 1 and 28 in Zone 3. REBOA inflation increased systolic blood pressure from 67 (40, 83) mm Hg to 108 (90, 128) mm Hg 5 minutes after inflation (P = 0.02). Cardiopulmonary resuscitation was ongoing during REBOA insertion in 17 patients (26.6%) and 10 patients (58.8%) had return of spontaneous circulation after REBOA inflation. The procedural complication rate was 6.6%. Overall mortality was 52%.
REBOA can be used in blunt and penetrating trauma patients, including those in arrest. Balloon inflation uniformly improved hemodynamics and was associated with a 59% rate of return of spontaneous circulation for patients in arrest. Use of the ER-REBOA catheter is technically safe with a low procedural complication rate.
