CO poisoning treatment study cut short after only two patients

NCT ID NCT06619717

Summary

This study aimed to find out whether one or three sessions of hyperbaric oxygen therapy works better to prevent long-term brain damage after carbon monoxide poisoning. Researchers planned to enroll adults with acute poisoning and test their memory, attention, and other thinking skills. However, the study was terminated early after enrolling only 2 participants, so no meaningful conclusions can be drawn.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber)
What this could lead to
If successful, this could clarify whether one or three hyperbaric treatments is better for preventing long-term brain problems after carbon monoxide poisoning.
What could go wrong
The study was terminated early with only 2 participants, so it cannot provide reliable answers. Results may not apply to all patients.
