Who is the anaesthesiologist?

An anaesthesiologist is a specialist whose primary responsibility is to ensure your safety and well-being during the surgery, and yours has been assigned to the operating theatre where you will undergo the scheduled operation. Your anaesthesiologist will administer anaesthesia before the surgery commences and stay with you throughout the surgery to ensure your safety and comfort. During this time, your critical life functions such as breathing, heart rate, blood pressure and body temperature will be monitored, as these will be affected by the surgery. The anaesthesiologist also plays the critical role of diagnosing and treating any medical problems immediately that may arise during your surgery or recovery period.

When will I meet my anaesthesiologist?

In general, your anaesthesiologist will meet you in the ward the day before your surgery. If you are admitted on the day of your operation, your anaesthesiologist will meet you before your surgery. During this meeting, the anaesthesiologist will carefully evaluate your medical history, perform a physical examination and review all laboratory tests to ensure that it is safe for you to undergo the surgery. In addition, the anaesthesiologist will explain to you the type of anaesthesia that is suitable for your surgery.

What are the types of anaesthesia?
1. General Anaesthesia
You will be rendered unconscious and have no awareness or sensation during the entire surgery. Heart surgery is performed under general anaesthesia.

2. Regional Anaesthesia

Your anaesthesiologist will inject local anaesthetic solution near a group of nerves to numb the part of your body that requires surgery. You may remain awake, or be given a sedative.

3. Local Anaesthesia

Some minor surgeries may only require injection of a local anaesthetic into the skin and tissues to numb the area where surgery is to be performed. Your anaesthesiologist, in consultation with the surgeon, will determine the most appropriate form of anaesthesia, taking into consideration your medical condition as well as your desires.
