Information for patients, parents and carers about your anaesthetic: as you/your child or young person is coming into hospital for a procedure or surgery this leaflet will give you important information and advice.

What is Pre-Assessment?

Preasssesment allows us to gather all the relevant information to ensure you/your child is prepared and well to proceed with the anaesthetic.

If your child or young person becomes unwell

Please telephone or email us, if your child or young person develops any of the following in the week leading up to their procedure or surgery:

  • Coughs, Colds, High Temperature
  • Diarrhoea or Vomiting
  • Contact with anyone with an infectious illness
  • Any Other Illness

Please leave your child’s or young person’s name, date of birth, and a contact number and we will phone you back as soon as possible.

Theatre times

If you have been asked to bring your child in at 7:30am their procedure will be between 9am and 1pm.

If you have been asked to bring your child in at 11am their procedure will be between 1.30 and 5pm.

Medication

Your child should have their usual medication on the day of their procedure unless we have told you not to. Please tell the anaesthetist, on the day, which medications your child has had. Please bring their medication with you on the day of their procedure.

Fasting (not eating)

It is important that your child or young person does not eat before their procedure. Please follow the instructions below:

Morning Fasting Instructions (7:30am admission)

Your child can have:

  • Food until 3:00 (in the morning)
  • Milk including formula until 5:00 (in the morning)
  • Breast milk until 6:00 (in the morning)
  • Clear fluids – until they arrive at the hospital. The staff will then give you further instructions.

Afternoon Fasting Instructions (11:00am admission)

Your child can have:

  • Food until 07:30 (in the morning)
  • Milk including formula until 09:30 (in the morning)
  • Breast milk until 10:30 (in the morning)
  • Clear fluids – until they arrive at the hospital. The staff will then give you further instructions.

What is a clear fluid?

Water, diluting juice, Dioralyte, still (not fizzy) drinks such as: Fruit Shoot, Capri-sun or flavoured water is allowed.

We recommend full sugar clear fluids whilst fasting to prevent low blood sugars.

Fasting instructions may differ for certain procedures or if your child or young person has certain health conditions. If this is the case, we will discuss this with you.

*Please note:

  • Chewing gum, boiled sweets and milkshakes are classed as foods.
  • Fluid thickeners and high protein formulas are also treated as food.

Common risks and events for children and young people having a general anaesthetic

Anaesthetics are considered very safe. It is common to have some mild and temporary side effects after a
general anaesthetic. These usually go away quickly and are not a cause for concern.

While the overall risk is low, it is important to remember that risks can vary depending on people’s health and the type of procedure. The anaesthetist will assess these factors during the pre-operative consultation.

Before your child’s procedure, you will meet the anaesthetist to discuss their medical history, any concerns you have, and your anaesthetic plan. This helps you understand the process and give informed consent.

Risks

Very common (more than 1 in 10 people): sore throat, agitation when waking from anaesthetic, sickness, temporary changes in behaviour e.g. anxiety, sleep problems.

Common (between 1 in 10 and 1 in 100 people): minor lip or tongue injury, discomfort at injection site.

Uncommon (between 1 in 100 and 1 in 1000): breathing problems, skin damage.

Rare (between 1 in 1000 and 1 in 10000): need for unplanned admission to intensive care, injury to eye, damage to teeth.

Very rare (1 in 10000 and 1 in 100000): anaphylaxis (allergic reaction to a drug), awareness during anaesthetic, death as a direct result of anaesthesia, long term disability.

Many everyday activities are riskier than the very small risks linked to anaesthetics.
