Before your Anaesthetic

Fasting

Before an anaesthetic, it is important for your stomach to be empty to reduce the risk of food or liquid entering your lungs. In most cases, this means no solid food, milk, or juice with pulp for at least 6 hours before your procedure. Clear fluids such as water, black tea or coffee (without milk), or clear apple juice may usually be consumed up to 2 hours beforehand. Essential medications may be taken with a small sip of water if advised by your doctor. Some hospitals use a “sip ‘til send” approach, which allows small sips of clear fluid until you are called for your procedure — the hospital will tell you if this applies to you. Always follow the exact fasting instructions given by your surgeon or anaesthetist, as these may vary depending on your age, health, or type of surgery. Eating or drinking outside the recommended times can increase risk and may delay or postpone your procedure.

Medications

Anaesthesia in Australia is provided by highly trained specialists known as Fellows of the Australian and New Zealand College of Anaesthetists (FANZCAs), and is very safe for most people. All Prime Anaesthetists are FANZCAs, meaning they have completed extensive training and are experts in providing safe, high-quality care. Like all medical procedures, anaesthesia carries some risks. Common temporary side effects include nausea, sore throat, drowsiness, and muscle aches. Less common risks include allergic reactions, breathing problems, or heart complications, which are more likely in people with serious medical conditions. Your anaesthetist will review your medical history, explain the specific risks for you, and take steps to minimise them. Serious complications are rare, and your anaesthetist’s main priority is your safety before, during, and after the procedure.

Fees

For most private hospital procedures, there are three main fees: the hospital, the surgeon, and the anaesthetist. You may also have additional fees such as pathology, x-ray and pharmacy. Anaesthetic fees are based on the complexity and length of your surgery, your health, and any special circumstances such as after-hours or emergency care. Your anaesthetist uses fee guidelines from the Australian Society of Anaesthetists (ASA), which reflect the time, skill, and resources needed for safe anaesthesia. Most health funds pay 25–40% of the Australian Medical Association (AMA) recommended rates for your anaesthetic care. This means the combined amount from Medicare and your health fund is often less than the anaesthetist’s fee, leaving a gap that you will need to pay. You will receive a written estimate before your procedure so you know the exact amount in advance.

Types of Anaesthesia

The type of anaesthesia you have will depend on your surgery, your health, and your personal needs. Your anaesthetist will discuss the safest and most comfortable option for you, and will be with you the whole time to monitor and care for you.

General Anaesthesia

You are fully unconscious and unaware during the procedure, so you won’t see, hear, or feel anything. Special medicines are given through a drip and/or breathing mask, and your anaesthetist will watch your breathing, heart, and other vital signs closely. You will wake up in the recovery area, where you will continue to be monitored until you are ready to return to the ward or go home.

Regional Anaesthesia

Medicine is used to numb a larger area of your body, such as the lower half (spinal or epidural) or an arm or leg (nerve block). You remain awake, but the numbed area will not feel pain. Gentle sedation can be given if you prefer to feel more relaxed during the
procedure.

Sedation (“Twilight Anaesthesia”)

You feel calm and comfortable, and may not remember much of the procedure, but you are still responsive. Sedation is often used for procedures such as endoscopies, minor surgery, and some dental or eye procedures, sometimes with local anaesthetic for added comfort.

Local Anaesthesia

Medicine is injected to numb a small, specific area of your body. You remain fully awake and aware, and will not feel pain in the treated area. This is often used for minor skin, dental, or eye procedures, sometimes together with sedation

Frequently Asked Questions

An anaesthetist is a specialist medical doctor with advanced training in anaesthesia, pain management, and the care of patients before, during, and after surgery. In Australia, anaesthetists are Fellows of the Australian and New Zealand College of Anaesthetists (FANZCAs) and typically complete at least 12 years of training after their university medical degree.

Your anaesthetist is present for the entire procedure. They monitor your vital signs such as breathing, heart rate, blood pressure, and oxygen levels while adjusting your breathing, medications, fluids, and body temperature to keep you safe and comfortable. Throughout the operation, they counteract the effects of the surgery itself, the anaesthetic medications, and any underlying health conditions, ensuring your body remains stable and well-supported.

In Australia, anaesthesia is provided by highly trained specialists. Serious complications are rare, and your anaesthetist will carefully assess your health to minimise risks.

No. Your anaesthetist ensures you remain comfortable and pain-free throughout your procedure. They will also plan pain relief for your recovery period.

For most private hospital procedures, there are three main fees: the hospital, the surgeon, and the anaesthetist. Additional fees may apply for services such as pathology, imaging, or pharmacy. All known anaesthetic fees will be provided before your procedure.

  • General anaesthesia – you are fully unconscious and unaware during the procedure.
  • Regional anaesthesia – numbs a large area of the body (e.g., spinal or epidural anaesthesia).
  • Local anaesthesia – numbs a small, specific area.
  • Sedation – you remain drowsy and relaxed, but not fully unconscious.

Your anaesthetist will recommend the safest and most suitable option for your surgery.

It’s important to share:

  • All medications, supplements, or herbal remedies you take
  • Any allergies or past reactions to anaesthesia
  • Your medical history, including heart or lung conditions, diabetes, or sleep apnoea
  • Whether you smoke, vape, or use recreational drugs
  • This information helps your anaesthetist plan a safe anaesthetic tailored to you.

Usually, you must fast (no food or drink) for several hours before surgery. Your anaesthetist or hospital will give you clear instructions, which you should follow closely to reduce the risk of complications.

You may feel drowsy, have a dry throat, or experience mild nausea. These effects are usually short-lived. Your anaesthetist will monitor you as you recover and adjust your pain relief as needed.

No. You should not drive, operate machinery, or sign legal documents for at least 24 hours after anaesthesia. Arrange for a responsible adult to take you home.
