Acute cerebral infarction treated with hydrogen and edaravoneScientific Research
Improved brain MRI indices in the acute brain stem infarct sites treated with hydroxyl radical scavengers, Edaravone and hydrogen, as compared to Edaravone alone. A non-controlled study
Medical Gas Research volume 1
In the acute phase of cerebral infarction, MRI indices (rDWI and rADC) worsened in the first 3-7 days after onset, and then gradually returned to normal in about 10 days (pseudo-normalization time), even after the tissue had infarcted. Since effective treatment can significantly improve these indicators and within the natural pseudo-normalization time, a comprehensive analysis of these changes provides an opportunity to objectively assess the effectiveness of different treatments for cerebral infarction. Hydroxyl free radicals are very destructive to tissues and will aggravate cerebral infarction. We treated patients with acute-phase brainstem infarction by intravenous administration of hydroxyl scavengers (edaravone and hydrogen gas) and assessed treatment efficacy by serial observation and analysis of these MRI markers.Treatment effects were assessed and compared in two groups (edaravone alone and edaravone and hydrogen combined) to assess the beneficial effects of hydrogen addition.
The patients were divided into edaravone alone group (group E, 26 cases) and edaravone combined with hydrogenated saline group (group EH, 8 cases). The initial hump amplitude in rDWI, the initial fall in rADC, and the pseudo-normalized time were measured continuously in each patient, and the mean of these data was compared between the two groups and with natural histories in the literature.
The rDWI initial hump of the E group reached 2.0, which was better than the natural history of 2.5, but not as good as the 1.5 of the EH group. The initial decline in rADC in the E group was 0.6, which was close to the natural history, but lower than the 0.8 in the EH group.The pseudo-normalization time for rDWI and rADC was 9 days only in the EH group and longer in the other groups. Adding hydrogen does not cause any side effects.
The use of hydroxyl radical scavengers in the acute phase of brainstem infarction improves MRI indices in the natural history. The effect of the EH group was more obvious and significant. These findings may imply the need for more frequent daily administration of hydroxyl scavengers or possibly additional hydrogen effects on scavenger mechanisms.
