Inhalation Sedation

 

Why is it used in dentistry?

Nitrous Oxide, also known as laughing gas, is used in dentistry due to its ability to decrease pain and anxiety in patients undergoing dental procedures. Nitrous oxide works by producing an analgesic, anxiolytic, and anesthetic effect.  It is commonly used in pediatric dentistry to relax children and decrease their fear of dental procedures. Nitrous oxide is also used for patients with underlying psychiatric conditions or patients with mental retardation.

How is it administered?

Unlike other sedation methods, nitrous oxide can be administered fairly easily with a breathing apparatus. A nasal mask that covers the nose is used to administer a continuous flow of nitrous oxide and oxygen to the patient during the dental procedure. A meter is used to control the flow and proportion of nitrous oxide and oxygen (usually 70% oxygen, 30% nitrous oxygen).

Advantages of NO2

• Nitrous Oxide works very fast. It only takes about 20 seconds for it to reach the brain. The relaxation and pain-killing effects occur after 2-3 minutes.

• The depth of sedation can be easily increased or decreased from moment to moment and the effects are almost instantaneous.

• Because NO2 leaves the body within 3-5 minutes after no longer being administered, there is no hangover effect.

• It is easy and comfortable to administer and does not require an injection.
