Summary

What Researchers Did

Researchers compared the efficacy of N-butylphthalide and dexamethasone combined with hyperbaric oxygen therapy versus hyperbaric oxygen monotherapy in 171 patients with delayed encephalopathy after acute carbon monoxide poisoning.

What They Found

At 1, 3, and 12 months post-treatment, patients receiving combined therapy showed significantly higher scores in cognition (MMSE, MoCA) and daily living activities (ADL) compared to the hyperbaric oxygen monotherapy group. The study reported no significant changes in blood glucose, lipids, or liver and kidney function, though some patients experienced minor side effects like loss of appetite or mild headache.

Canadian Relevance
