If you’re preparing for surgery, your thoughts often move past the procedure itself to a more immediate question: What actually happens when you go under?
Anaesthesia in plastic surgery is usually only discussed briefly, yet it is the part patients commonly feel most uncertain about. You may be wondering whether you will be fully asleep, how your breathing is supported, and what risks are involved.
This article explains the different types of anaesthesia, how the approach is chosen, and the potential side effects and complications to understand before surgery.

Why Anaesthesia is an Important Part of Your Surgical Plan
In plastic surgery, anaesthesia is not only used to prevent discomfort. Surgical procedures trigger natural protective responses in the body, including movement, pain reflexes, muscle tension and stress hormone release.
Anaesthesia is used to temporarily control these responses so surgery may be performed accurately and without distress.
By relaxing muscles, limiting pain signals and stabilising breathing and circulation, anaesthesia allows the surgeon to operate in a controlled environment.
Without this controlled state, even minor operations would be difficult to perform. For this reason, anaesthesia is considered a central part of the surgical plan, not a separate step.
The Different Types of Anaesthesia Used in Plastic Surgery
Plastic surgery may be performed using different forms of anaesthesia depending on the procedure and the individual patient. The aim is to provide appropriate comfort while maintaining stable body functions during the operation.
The main categories include:
- Local Anaesthetic: Numbs a specific area while you remain awake. It may be used for minor skin procedures, small excisions or limited eyelid surgery.
- Sedation: You are relaxed and may have reduced awareness or memory of the procedure. May be considered for some facial procedures or limited liposuction areas.
- General Anaesthetic: A controlled state of unconsciousness where breathing and vital functions are supported and monitored. Commonly used for procedures such as abdominoplasty, breast surgery or combined procedures.
Each option differs in the level of awareness and monitoring required, and the choice is based on the procedure and your health background.
How the Type of Anaesthetic is Chosen
The choice of anaesthetic is based on a combination of the procedure and the individual patient rather than a single preferred method.
Factors such as the length and complexity of surgery, your medical history, medications and previous reactions to anaesthesia are reviewed during the pre-operative assessment to help determine the most appropriate approach.
Your comfort and level of anxiety may also be considered, and the plan is discussed between you, the surgeon and the anaesthesia provider.
Understanding the Risks of Anaesthesia
All forms of anaesthesia carry some level of risk because they temporarily affect breathing, circulation and protective reflexes.
For most healthy patients, serious complications are uncommon, but they are not impossible, and the level of risk varies depending on overall health, medications and the type of procedure performed.
Common Temporary Side Effects
After anaesthesia, some short-term effects may occur while the body processes the medications. These usually settle as the drugs wear off, but their duration and intensity vary between individuals and the type of anaesthetic used.
Common temporary effects may include:
- Nausea or vomiting
- Sore throat
- Drowsiness or fatigue
- Headache
- Shivering
- Bruising or discomfort at the IV site
These effects are generally manageable and monitored during recovery, although they may feel unpleasant in the early post-operative period.
Less Common Complications
More significant complications may occur when anaesthesia affects breathing, circulation or the body’s protective reflexes.
Examples may include:
- Breathing difficulties
- Aspiration of stomach contents into the lungs
- Allergic reactions to medications
- Significant changes in blood pressure
- Irregular heart rhythms
- Blood clots
- Awareness during anaesthesia (rare)
The likelihood of these complications varies depending on overall health, the procedure being performed, and the type of anaesthetic used. Continuous monitoring is intended to detect changes early so they may be managed appropriately.
Rarer Risks
Severe complications from anaesthesia are rare, particularly in otherwise healthy individuals undergoing planned surgery. However, because anaesthetic medications affect vital functions, serious events may still occur in uncommon circumstances.
Rare but severe risks may include:
- Severe allergic reaction (anaphylaxis)
- Cardiac complications, including a heart attack
- Stroke
- Brain injury related to prolonged oxygen deprivation
- Death
While these outcomes are uncommon, they are part of the informed consent discussion so patients may make decisions with a clear understanding of potential risks.
Make an Informed Decision With Dean White
Anaesthesia is a routine part of modern surgery, but it should not be viewed as trivial.
It is a carefully planned medical process intended to support the body during an operation, and understanding both its role and its risks may help patients approach surgery with realistic expectations.
Discussing concerns openly with your surgeon and anaesthesia provider allows the plan to be tailored to your health and the procedure being considered.
During consultation, Associate Professor Dean White’s role is to help you understand how the operation and anaesthetic interact, and what this may mean in your individual situation.
