Laughing Gas Sedation
Laughing gas (Nitrous Oxide) is the mostly examined sedation technique. It was discovered in 1772.
The gas has an anxiolytic, relaxing and painkilling effect. Most people have after a few minutes an euphoric feeling, sometimes in combination with a tingling sensation in arms and legs or a warm feeling all over.
When the treatment is done the gas is elaminated from the body within 3 to 5 minutes, so that you can drive home safely.
