Our doctors perform so many different procedures, treatments, and operations that you may not find out everything you want to know here. Don’t worry, though, because once you’re in hospital your doctors and nurses will be able to answer all of your questions. They’ll be able to tell you exactly what’s going to happen and when it’s going to happen.

Below we have prepared a list of some of the things that might happen as you are preparing for theatre.


An anaesthetic is a medication given to you either by an injection or by breathing it in through a small mask that you wear over your nose and mouth. Once you have been given this anaesthetic, you’ll either be completely relaxed or fast asleep during your operation so you won’t feel any pain at all.

A member of your medical team will also discuss the safety of anaesthesia with you prior to any procedure taking place.

There are two types of anaesthetic that we use operations. They are:

  1. General Anaesthetic: A general anaesthetic will put you fast asleep. When you are under general anaesthetic you won’t feel a thing. You may not even remember what has happened when you wake up.

2. Local Anaesthetic: A local anaesthetic means you’ll stay awake during your operation but you won’t feel any pain. The anaesthetic will numb all of your pain sensations so the only thing you’ll feel is a little bit of pressure or movement.

Your anaesthetic will be given to you by a doctor called an Anaesthetist. An anaesthetist is an expert who specialises in giving anaesthetics to patients for their operations. Your anaesthetist will stay with you all the time that you are asleep or numbed. They will be there to make sure you are ok and they’ll be keeping an eye on things like your breathing, your pulse, your blood pressure, and your temperature.

Most of all, though, they’ll be making sure you are comfortable, relaxed, and feeling no pain during your whole operation.


Fasting is an important part of preparing for many medical procedures especially if you are going to have an anaesthetic. Fasting prevents you from being sick while under anaesthetic or during treatment. A member of your medical team will tell you before any procedure whether you need to fast and, if so, for how long.


If you are over 16 years of age you may be asked to give consent of any procedure you have at Our Lady’s Children’s Hospital.

If you are asked to make these important decisions you will be free to discuss them with your parent(s) beforehand.

Your medical team will provide you will all the necessary information before any procedure takes place and they will answer all your questions to ensure you are completely informed about what to expect.
