What is a cannula?
A cannula is a small, short piece of plastic tube that is put directly into the vein to give medications or fluids. It is not a needle. A short plastic extension tube is then attached to the cannula to protect the cannula and make giving medication easier. It should be taped down with a clear dressing so the cannula can be seen. It may be covered with a soft sock-like bandage for extra protection.
Why is my child going home with a cannula?
If your child is medically stable but needs to have further intravenous (IV) medication, your doctor may send your child home with the cannula in.
You may need to bring your child back to hospital for treatment or a hospital in the home (HITH) nurses may come to your home to give medication.
How do I care for the cannula at home?
- Do not touch the cannula unless necessary.
- Do not take the tape off.
- Do not pull at the cannula.
- Do not inject anything into the cannula.
- Do not get the cannula or dressing wet. Your child can still bath or shower but keep the cannula out of the water and cover the cannula with a plastic bag and sticky tape.
