[|Human|] My 4 year old had a cavity filled yesturday and was put on some gas to calm her but not put her to sleep. That night she threw up and was seeing colored spots in the air and falling silky lights. Today she still hurts in her stomach and is seeing the same lights. Our doctor told us to call the dentist becasue he did not know about the gas used (NO2 I think). What could cause this and should we be worried? We ar giving her Pedialite and childrens Pepto.
[|AI|]  Hello thanks for consulting at Chat Doctor.the most common side effects of N2O are Nausea and vomiting. As a result of rapid release of nitrous oxide from the blood stream into the alveoli, thereby diluting the concentration of oxygen. This may lead to headache and disorientation. If the problem continues it can be avoided by administering 100 percent oxygen after nitrous oxide has been discontinued. For vomiting --to avoid deny Chat Doctor.
