Inhaled Hydrogen Efficacy on Neurological Outcome Following Brain Ischemia During Post-cardiac Arrest Care

Inhaled molecular hydrogen gas (H2) has been shown to improve outcomes in animal models of cardiac arrest (CA). H2 inhalation is safe and feasible in patients after CA. We investigated whether inhaled H2 would improve outcomes after out-of-hospital CA (OHCA).
The trial was terminated prematurely because of the restrictions imposed on enrollment during the COVID-19 pandemic.
Between February 1, 2017, and September 30, 2021, 429 patients were screened for eligibility, of whom 73 were randomly assigned to H2 (n = 39) or control (n = 34) groups.
The primary outcome, i.e., a CPC of 1 or 2 at 90 days, was achieved in 22 (56%) and 13 (39%) patients in the H2 and control groups, respectively.
