TL;DR
Scientists have found that several types of medical gases like hydrogen and oxygen can protect brain and nerve cells from damage in lab studies, but doctors aren't using them yet because we don't have enough real-world proof that they actually work in patients. They need to do more human studies to figure out which gases really help and how to use them safely before hospitals can start treating people with them.
Key Finding
Multiple medical gases including hydrogen show significant neuroprotective potential in laboratory and animal models across various types of neural injury, but none have been successfully translated into clinical practice due to insufficient human evidence and conflicting trial results.
Summary
This review examined research on several medical gases—including hydrogen, oxygen, and others—that show promise in protecting brain and nerve cells from injury in laboratory studies. While decades of research suggest these gases could help treat conditions like stroke, brain trauma, and nerve damage, none have been widely adopted in clinical practice yet. The authors found that although different gases work through similar protective mechanisms at the cellular level, there isn't enough reliable human evidence and some studies contradict each other, which has prevented these treatments from moving into regular medical use.
Practical Takeaway
While this review identifies hydrogen among gases with theoretical neuroprotective properties, it emphasizes that the evidence remains largely preclinical (laboratory and animal studies). The authors note that contradictory results and lack of robust human trials are major barriers to clinical use. Anyone interested in hydrogen water should recognize that this review does not provide evidence supporting its use for brain or nerve protection in humans—only that the concept warrants further rigorous clinical investigation.
Abstract (excerpt)
The neuroprotective properties for certain medical gases have been observed for decades, leading to extensive research that has been widely reported and continues to garner interest. Common gases including oxygen, hydrogen, carbon dioxide and nitric oxide, volatile anesthetics such as isoflurane…
