Laughing gas studied for pain relief: early results show promise?
NCT ID NCT01581450
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed Phase 1 study tested whether 35% nitrous oxide (laughing gas) can reduce pain sensitivity in 20 healthy men. Researchers used electrical stimulation to create temporary pain and measured how the gas affected the area of increased sensitivity. The study also monitored vital signs and sedation levels to check safety.
