TL;DR

Breathing in hydrogen gas during a special lung treatment before transplant helps improve the function of donated lungs after the donor's heart has stopped beating.

Key Finding

Lungs ventilated with 2% hydrogen gas during preservation showed significantly better function, reduced inflammation and cell death, and less fluid accumulation compared to lungs ventilated with room air, with benefits persisting after transplantation.

Summary

Researchers tested whether adding hydrogen gas to the air used to ventilate donor lungs during preservation could improve their function before transplantation. In a study using pigs, lungs treated with 2% hydrogen gas showed better oxygen exchange, less inflammation, less cell death, and less fluid buildup in the lung tissue compared to lungs treated with regular air. These improvements remained visible even after the lungs were transplanted into recipient animals.

Practical Takeaway

This is an early-stage animal study suggesting hydrogen gas may help preserve donor lungs for transplantation by reducing damage. However, this research has not been tested in humans, and the findings cannot yet be applied to hydrogen water or other consumer hydrogen products. Much more research would be needed to determine if this approach could benefit transplant patients.

Abstract (excerpt)

Background: Ex vivo lung perfusion (EVLP) is a system that circulates normothermic perfusate into procured lungs, allowing for improved lung function and lung assessment. We investigated whether ventilation with hydrogen gas during EVLP improves the donation after cardiac death lung function…
