NItrous Oxide (Laughing Gas)
Nitrous oxide is a colorless and virtually odorless gas with a faint, sweet smell. It is an effective analgesic/anxiolytic agent causing central nervous system (CNS) depression and euphoria with little effect on the respiratory system. Nitrous oxide is administered by having a nasal hood (with flavored scents) where the child will breathe a mixture of the nitrous oxide and oxygen. We commonly use this method for children 4 years and older.
The objectives of nitrous oxide/oxygen inhalation include:
- Reduce or eliminate anxiety
- Reduce untoward movement and reaction to dental treatment
- Enhance communication and patient cooperation
- Raise the pain reaction threshold
- Increase tolerance for longer appointments
- Aid in treatment of the mentally/physically disabled or medically compromised patient
- Reduce gagging
