Anaesthesia information

The type of anaesthesia used for your procedure depends on what you're having done, your general health, and your own preferences where there's a choice. This page gives a general overview of what's involved. More information on anaesthetist's fees is outlined on our Surgery Costs page, and specific fasting instructions are covered under Preparing for Surgery.

What to expect

Local anaesthesia

Numbs a specific area while you remain fully awake. Used for minor procedures where sedation isn't necessary. Recovery is typically quickest with this option, as there's no drowsiness to wear off afterwards.

Local anaesthesia with sedation

Often called "twilight" anaesthesia, this combines local numbing with medication to help you relax and feel comfortable, while remaining able to breathe on your own. You may have little to no memory of the procedure afterwards.

General anaesthesia

Used for more involved surgical procedures. You are fully asleep and unaware throughout, with your breathing and vital signs continuously monitored by a specialist anaesthetist for the duration of the procedure.

Your anaesthetist

For procedures requiring sedation or general anaesthesia, your anaesthetic is delivered by a specialist anaesthetist — a qualified medical doctor with specific training in anaesthesia and perioperative care. They are responsible for your safety and comfort throughout the procedure, and for monitoring you as you wake up afterwards.

Where appropriate, you may have the opportunity to speak with your anaesthetist before your procedure to discuss your medical history and ask any questions specific to your situation.

What we need to know

To keep your anaesthetic as safe as possible, please let us know about:

• Current medications and supplements, including anything over-the-counter or herbal
• Allergies, particularly any previous reactions to medications or anaesthesia
• Previous anaesthetics, including any complications or unusual reactions
• Medical conditions such as heart, lung, or airway issues, sleep apnoea, or reflux
• Smoking, as this can affect both anaesthesia and healing — see our Preparing for Surgery page for more
• Fasting — you'll be given specific fasting instructions ahead of your procedure, which must be followed for your safety
