What Anaesthetic Choices Do You Offer?

Dr Chan offers both general anaesthesia (performed at an accredited day surgery) and deep (twilight) sedation (performed at Dr Zion Chan’s Operating Suites) . You can choose either anaesthetics. Dr Chan prefers twilight sedation as it offers a faster recovery for our patients and less anaesthetics complications. Our Clinic has been performing this type of anaesthetics for more than 10 000 patients over a 30 years span, since Dr Eng Peng Tan (Dr Zion Chan’s Mentor) whose practice Dr Chan took over in 2008. There has not been any major adverse effects for this type sedation compared to a prolonged recovery period, more morbidity and a mortality rate of 1 in 200 000 for general anaesthetics.


Every Surgeon in Australia has been trained in GA. Dr Chan is no different. GA uses a higher doses of anaesthetics hence more side effects, uses a machine to breathe for you and medications can cause severe anaphylaxis and malignant hyperthermia. Both conditions can be fatal. The mortality rate is 1 in 200 000 for GA which is not acceptable for most cosmetic surgical procedures. However some procedures has to be done under GA like a tummy tuck and big facelift procedures.


Dr. Chan prefers a method called Twilight Sedation using a Consultant Anaesthetist who specialises in Twilight Sedation for the last 15 years. Not every surgeon is comfortable with this type of sedation because of the steep learning curves. Dr Chan after been trained fully in GA surgeries, spent extra 3 years with his mentor Dr Eng Peng Tan and learnt and mastered doing surgery under sedation anaesthetics. Therefore Dr Chan can provide a more diversified anaesthetic options for his patients. With this type of sedation, less anaesthetic drugs are used to keep you asleep and comfortable, hence less side effects. Patients require less time to recover from surgery and experience fewer side effects such as nausea, vomiting, swelling and bruising. Twilight Sedation is best described as being in a deep sleep but still in control of your reflexes. This means that you are breathing on your own throughout the procedure. In Australia, both twilight sedation and general anaesthetic, administered by consultant anaesthetists, are of a world-class standard. Our Consultant Anaesthetist and surgeon prefer twilight anaesthesia because of the inherent safety, reduced side effects and suitability of twilight anaesthesia for cosmetic surgery. After the surgery, you will spend an estimated two hours in a recovery area. Here you will be given pain relief if required. You are kept here until the anaesthetist is satisfied you are fit to be discharged. COMMON QUESTIONS AND ANSWERS
  • What is Twilight anaesthesia? Twilight anaesthetic is a combination of
    1. Intravenous sedation to cause a sleepy state
    2. Local anaesthesia to remove pain at surgery
    Twilight anaesthesia should be approached with adequate preparation whereby on the morning of surgery you are already calm and relaxed, comfortable and confident. The intravenous sedation is administered by a specialist anaesthetist who is assisted by a trained anaesthetic nurse. Amnesia is not essential, however most patients have no recollection. Intravenous medication is administered along the way according to your needs to keep you at the optimum level of sedation and deep sleep.
  • Will I be in any pain? Before surgery commences and whilst you are asleep, you will be given local anaesthetic which will numb the area and you should NOT be in any pain or uncomfortable. You are not paralysed and can respond if need be. The anaesthetist will be by your side, to be in touch with you, for the entire operation to ensure your comfort and safety.
  • How else will my memory be affected? Most people don’t remember anything about the operation. Sometimes, you don’t even remember how you got home. However, your memory will be back to normal by the following day.
  • Is twilight anaesthetic safe? Yes. Twilight anaesthesia is very safe. It is widely accepted to be much safer than general anaesthesia.
  • I have been sick after a general anaesthetic before. Will I be sick after this anaesthetic? Please indicate this in your medical history. There is a possibility that you may also be sick after this anaesthetic although the likelihood is much less. The anaesthetist will discuss this with you. We will administer anti-nausea medication which will help to prevent this.
  • How will I feel after the anaesthetic? You will feel very relaxed and drowsy for a few hours afterwards. You should sleep off the effects when you get home. You may feel clear and confident but under no circumstances should you engage in activities like driving as your coordination is temporarily impaired.
  • Can I eat afterwards? Yes. You can eat and drink as soon as you feel like it. Try small portions for a start. It is particularly important to keep up your fluid intake to stay well hydrated.
  • What if I have any other concerns? Please include a full disclosure of your concerns regarding any anaesthetic experiences, during your consultation. Indicate this on your medical history form. Your anaesthetist will see you prior to your operation and will discuss this with you if they have not been dealt with already.

General Anaesthesia vs Twilight Sedation with Local Anaesthesia

Twilight Sedation – The medication is lighter, safer, has less side efffects, ensuring a faster, simple recovery. General anaesthesia has a mortality rate of 1 in 200 000.

Hospital vs Day Surgery Procedure

Well equipped day surgery facilities should and are fully equipped to manage any emergencies. A Consultant Anaesthesist provides excellent service in any equipped environment they work in. Small private day centres have advantage of less and even no hospital infections and quality of service can be extremely high with tight control.
