H2HUBB TAKEAWAY

In 184 patients, the numerical rating scale (NRS) pain scores were higher in the hydrogen group (4.08 ± 1.77) than the control group (3.54 ± 1.77) on day 1 (p < 0.05); however, the mean difference between the two groups was small (1 to 1.6).

What the Researchers Studied

The researchers used prophylactic inhalation of hydrogen gas in elderly patients undergoing elective surgery to compare their occurrence of postoperative delirium with that of controls.

How the Study Was Conducted

Randomized human clinical trial.

How Molecular Hydrogen Was Used

A total of 184 patients aged ≥ 65 years were enrolled and randomized into either a control group or a hydrogen inhalation group.

What the Researchers Found

The numerical rating scale (NRS) pain scores were higher in the hydrogen group (4.08 ± 1.77) than the control group (3.54 ± 1.77) on day 1 (p < 0.05); however, the mean difference between the two groups was small (1 to 1.6).
