Depression is a condition that haunts millions of people all over the world, and at times, can be very difficult to treat. Nitrous oxide, which is an anesthetic used in dental procedures to help relax the patient, is now being thought of as a possible remedy for severe depression that has not responded to other forms of treatment. A study performed at Washington University School of Medicine in St. Louis by Peter Nagele had shown that out of 20 people who had depression, which did not improve with typical treatment, about two-thirds of the participants demonstrated an improvement in their symptoms after receiving nitrous oxide.
Supposedly the participants were evaluated twice over a 24-hour period and it seems that the results of the study are encouraging. Sergio Andrade Andrade Gutierrez is glad to hear it went so well. Since the effects of the nitrous oxide wear off relatively quickly after inhalation is stopped, the main side effect found was nausea and vomiting, but one day later, the participants still demonstrated an improvement in symptoms.
