Sedation, explained plainly

Laughing gas, oral sedation and general anesthesia: what each one is, when it makes sense, and the questions worth asking.

The short version

  • Laughing gas: mild, fast on and fast off, child stays awake
  • Oral sedation: deeper relaxation, needs a quiet day afterward
  • General anesthesia: complete care in one visit while asleep, with an anesthesia team

Most children do well with a gentle, step-by-step approach and no medication at all. For some, a little extra help turns a stressful visit into a calm one. Here are the options, from lightest to deepest.

1. Laughing gas (nitrous oxide)

Breathed through a small nose mask, nitrous oxide takes the edge off anxiety and helps with comfort. The AAPD recognizes it as a safe and effective technique for children. It takes effect quickly and wears off within a few minutes of breathing pure oxygen at the end, so most kids go back to school or normal activities the same day. Children stay awake and can talk with us throughout.

2. Oral sedation

A liquid medicine given before treatment for more anxious children or longer appointments. Children are relaxed and drowsy but not asleep. Your child will be monitored throughout, needs an adult with them afterward, and should have a quiet rest of the day.

3. General anesthesia

For young children who need a lot of treatment, children with significant anxiety, or some children with special health care needs, the safest path can be to complete everything in one visit while they sleep. This is done in our dedicated pediatric surgery center with an anesthesia provider monitoring your child the entire time.

You may have read about an FDA warning: in 2016 the FDA said that repeated or lengthy (more than three hours) use of general anesthesia and sedation drugs in children under 3 may affect brain development, while also noting that a single, relatively short exposure is unlikely to have negative effects. We weigh this carefully with you, especially for very young children.

Questions worth asking

  • Why is sedation recommended for my child, and what are the alternatives?
  • Who will monitor my child, and what training do they have?
  • What are the eating and drinking instructions before the visit?
  • What should I expect afterward, and when should I call?

Always follow the specific eating and drinking instructions your team gives you before sedation. They are there for your child’s safety.
