Purpose: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is beneficial for uncontrollable torso bleeding; however, prolonged REBOA causes ischemia-reperfusion injury. The purpose of this study is to examine the hypothesis that continuous renal replacement therapy (CRRT) with a cytokine-adsorbing hemofilter would improve mortality due to hemorrhagic shock with REBOA-reperfusion injury by controlling metabolic acidosis, hyperkalemia, and hypercytokinemia.
Methods: Hemorrhagic shock with 40% blood loss was induced by phlebotomy in eight female swine.
Hydrogen gas inhalation therapy may not work sufficiently to mitigate oxidative stress induced with REBOA.

Hemorrhagic shock is a significant cause of trauma-related mortality. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less-invasive aortic occlusion maneuver for severe hemorrhagic shock but potentially inducing oxidative stress injuries. In an animal model, this study investigated hydrogen gas inhalation therapy's potential to mitigate post-REBOA ischemia-reperfusion injuries (IRIs).

Background: Intra-aortic balloon pump (IABP) and resuscitative endovascular balloon occlusion of the aorta (REBOA) are two endovascular intervention methods for circulatory support. The aim of this study was to compare the hemodynamic effects of simultaneous mechanical chest compressions (MCC) with IABP, REBOA and those with only MCC (overall and detailed in the MCC cycle) and return of spontaneous circulation (ROSC) during cardiopulmonary resuscitation (CPR) in experimental non-traumatic cardiac arrests (CA).
Method: CA was electrically induced (ventricular fibrillation) in 24 anesthetized pigs, which then were randomized to MCC synchronized IABP (n = 8), total occluded REBOA (n = 8), or control (n = 8).

Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
