TL;DR
Scientists found that special gases you can breathe in might help protect people's brains after a serious head injury, and these gases could be easier and faster to use than regular medicines because they go into your body super quickly through your lungs.
Key Finding
Hydrogen gas, hydrogen sulfide, and nitric oxide are identified as promising inhaled therapies for traumatic brain injury that may offer advantages over traditional drug treatments due to their ease of delivery and rapid absorption into the body.
Summary
This review article examined different gases that can be breathed in to protect the brain after traumatic brain injury (TBI). Researchers looked at both animal studies and human trials testing gases like hydrogen, hydrogen sulfide, nitric oxide, xenon, and argon, as well as the established treatment of hyperbaric oxygen (breathing oxygen at higher-than-normal pressure). The review suggests these inhaled gases may help reduce brain damage by fighting oxidative stress (harmful chemical reactions that damage cells).
Practical Takeaway
This is a review article summarizing existing research rather than a new study with results, so it does not provide direct evidence about hydrogen gas effectiveness in humans. The review suggests hydrogen gas is a promising area for TBI research, but clinical trials in humans are needed before any conclusions can be drawn about its practical use.
Abstract
Despite multiple prior pharmacological trials in traumatic brain injury (TBI), the search for an effective, safe, and practical treatment of these patients remain ongoing. Given the ease of delivery and rapid absorption into the systemic circulation, inhalational gases that have neuroprotective properties will be an invaluable resource in the clinical management of TBI patients. In this review, we perform a systematic review of both preclinical and clinical reports describing inhalational gas therapy in the setting of TBI. Hyperbaric oxygen which has been investigated for many years, and some of the newest developments are reviewed. Also, promising new therapies such as hydrogen gas, hydrogen sulfide gas, and nitric oxide are discussed. Moreover, novel therapies such as xenon and argon gases and delivery methods using microbubbles are explored. Key Words: traumatic brain injury, head trauma, oxidative stress.
