Xenon Gas Dramatically Improves Head Injury Recovery in Mice

(Cosmos Magazine) – The anaesthetic gas xenon has dramatically reduced long term death and disability in brain-injured mice, prompting researchers to call for a trial in humans.

Led by trauma researcher Robert Dickinson, from Imperial College London in the UK, the team found xenon given to head-injured mice preserved memory, reduced biomarkers of trauma, and led to a more than eight-fold improvement in survival at 12 months.

Xenon is one of the so-called “noble gases” that include argon and neon, and has been touted as the perfect anaesthetic, held back chiefly by its high price tag.

The researchers have previously shown that mice given xenon after brain trauma had less bruising and better neurological outcomes for up to a month afterwards. The current study followed mice for nearly two years. CONTINUE
