Animal StudyHighlightedPerioperatively Inhaled Hydrogen Gas Diminishes Neurologic Injury Following Experimental Circulatory Arrest in SwineMHID-8554516PMID: 310619202019JACC: Basic to Translational ScienceAlexis R. Cole, BS, Dorothy A. Perry, MBCHB, Ali Raza, MD, Arthur P. Nedder, DVM, Elizabeth Pollack, DVM CANDIDATE, William L. Regan, CCP, LP, et al.This study used a swine model of mildly hypothermic prolonged circulatory arrest and found that the addition of 2.4% inhaled hydrogen gas to inspiratory gases during and after the ischemic insult significantly decreased neurologic and renal injury compared with controls. With proper precautions, inhalational hydrogen may be administered safely through conventional ventilators and may represent a co
