Nitrous oxide
Disclaimer: This fact sheet is for education purposes only.
Please consult with your doctor or other health professional to
make sure this information is right for your child.
 You may know this gas as happy gas (often given at the dentist). It is sweet smelling and will make your child feel drowsy quickly. The gas helps to take away the pain and anxiety they may be feeling. Your child may need nitrous oxide gas while the doctor or nurse carries out a procedure such as stitches, dressings or a blood test.
They will be given a mask attached to a machine through which your child will breathe the gas. This gas is safe for use in children and there are no long-term side effects. It will be given by a nurse or doctor. Your child will need to stop eating and drinking for at least two hours before they have the gas so that they do not vomit.
You are welcome to stay while your child is having the gas. The best thing you can do is to stay where your child can see you and hold their hand. The gas will be given a few minutes before the procedure starts and will continue until it is finished. Your child will then be given oxygen through the same mask to clear the gas from their lungs.
Young children may not like having a mask on their face. The mask may need to be held firmly over their face at first until the gas starts to work. The gas will make your child feel "floaty", warm and tingly. Your child may not remember anything about the procedure. They may feel angry or confused by the gas and will need you to stay close and comfort them.
Hospitals can be frightening places for children. If a child feels sick or is in pain, it can be upsetting to have nurses and doctors whom they don't know look after them. It is important to stay with your child to look after and comfort them. If your child asks about the tests being done, reassure them and explain in simple terms what is being done and why. Always tell the truth.
At times it is helpful to tell stories, talk about the family or anything else that may help to take their mind off the procedure. Remain calm and comfort your child, if you get upset so will your child. The staff are there to help you and your child. If you would like more information please ask the nurse or doctor caring for your child.
