Nitrous Oxide Dental Sedation:
Nitrous Oxide Dental Sedation Dentistry is the use of a mixture of Nitrous Oxide and Oxygen Gas to achieve a comfortable level of Sedation for a patient to comfortable tolerate a Dental Procedure. Nitrous Oxide is delivered through a nose piece where the patient breathes in the Sedative gases. The Nitous gas is typically adjusted between the range of 20% up to 70% Nitrous with the remaining gas being Oxygen Gas. Most patients will achieve comfortable Dental Sedation in the range of approximately 50% Nitrous Oxide and 50% Oxygen.
Nitrous Oxide Dental Sedation is very effective for mild to moderate dental anxiety. Patients can eat or drink prior to having Nitrous Oxide Dental Sedation, it is very non-toxic and there is no hang-over effect. The effects of Nitrous Oxide Dental Sedation wear off very quickly and patients can drive a car 30 minutes after a sedation appointment and carry on with the day as if nothing ever happened.
Nitrous Oxide has been proven to be the sedation method of choice for patients who are mild to moderately anxious. The speed of onset, margin of safety, low incidence of side effects, patients can drive afterwards and no hangover effect all make Nitrous Oxide sedation very popular among dental practitioners as well as anxious patients. Nitrous Oxide also works moderately well in suppressing gag reflexes. One know absolute contraindication is pregnancy. Pregnant women should never be sedated with Nitrous Oxide.
Care should be used when Nitrous Oxide is used in combination with other oral sedatives such as Valium, aka. Diazepam, Xanax and other sedatives or anti-anxiety medications. Never pretreat yourself with an oral sedative without telling your dentist or caregiver/treating doctor you have done so. Nitrous Oxide in combination with oral sedatives can push a patient into General Sedation. If a dentist is not trained in handling General Sedation or the facility is not equipped for General Sedation, the combination of an Oral Sedative and Nitrous Oxide can produce an emergency with a potential poor outcome.
