NCT05282836

Brief Summary

This was a randomized, single-center trial. On the basis of standard-of-care, patients in the treatment group inhaled H2-O2 (66% hydrogen; 33% oxygen) at 3 L/min via nasal cannula by using the Hydrogen/Oxygen Generator (model AMS-H-03, Shanghai Asclepius Meditech Co., Ltd., China) during a 7-day stay in the intensive care unit. Patients in the control group received standard-of-care (consisting of oxygen therapy) alone. This study intends to apply Hydrogen/Oxygen Generator in clinical patients with aneurysmal subarachnoid hemorrhage (aSAH), exploring the role of hydrogen-oxygen mixed gas inhalation therapy in early brain injury, and the prevention of cerebral vasospasm and delayed cerebral ischemia, finally providing a scientific basis for hydrogen treatment of aSAH.

Intervention

EXPERIMENTAL

H2-O2 (66% hydrogen; 33% oxygen) inhalation. Patients in the treatment group inhaled H2-O2 (66% hydrogen; 33% oxygen) at 3 L/min via nasal cannula by using the Hydrogen/Oxygen Generator (model AMS-H-03, Shanghai Asclepius Meditech Co., Ltd., China) during a 7-day stay in the intensive care unit.

Device: Hydrogen Oxygen Generator with Nebulizer

No intervention

NO INTERVENTION

Usual care refers to the standard-of-care (including oxygen therapy) recommended by guidelines.
