Hydrogen gas post-conditioning attenuates early neuronal pyroptosis in a rat model of subarachnoid hemorrhage through the mitoKATP signaling pathway.

In rats, hydrogen gas reduced brain swelling, improved neurological function, and lowered markers of oxidative stress and neuronal pyroptosis after subarachnoid hemorrhage. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.
