What is a general anaesthetic?

A general anaesthetic is a combination of drugs that produce deep sleep. It is used for procedures as it causes a loss of sensation. Your child will not be aware of what is happening and afterwards will not remember anything that has happened.

What are the benefits?

Your child needs to have a procedure. So that your surgeon or doctor can perform the procedure safely, your child needs to be in a state where they do not move and their muscles are relaxed. A safe way to achieve this is to give your child a general anaesthetic.

Are there any alternatives?

For certain procedures, such as a scan, your child may be able to have sedation. This can be given in a variety of ways such as a syrup or nose spray.

For smaller procedures, your anaesthetist may consider a local anaesthetic injected near the area of surgery.

The options depend on how mature your child is and their ability to stay calm and still.

How is a general anaesthetic given?

Most older children are sent to sleep by injecting the anaesthetic through a small tube (drip) in a vein. The injection takes about 30 seconds to work.

Some children prefer to go to sleep by breathing an anaesthetic gas through a face mask. This technique is more common in younger children and babies. Your child may be a bit restless as the gas begins to work but it usually takes only a minute for them to go to sleep.

When the procedure has finished, the anaesthetic wears off, allowing your child to wake up again.

What complications can happen?
