Before your procedure, your anaesthetist will discuss the available anaesthetic options with you and agree on the most suitable plan. Your anaesthesia may involve one or a combination of the following:
General Anaesthesia
General anaesthesia is commonly required for a wide range of surgical procedures. It induces a controlled state of unconsciousness, ensuring you feel nothing and have no memory of the operation. Anaesthetic drugs are administered either through an injection into a vein or by inhaling anaesthetic gases. These medications prevent the brain from processing sensory signals from the body. Throughout the procedure, the anaesthetic team closely monitors your vital signs, and your anaesthetist remains by your side at all times, ensuring your safety and comfort.
Regional Anaesthesia
Regional anaesthesia numbs a specific group of nerves in the area where surgery is being performed. Common techniques include spinals and epidurals, which are frequently used for procedures such as caesarean sections, bladder surgeries, and hip or knee replacements. Another form of regional anaesthesia is a nerve block, where an injection is placed near a nerve or a nerve plexus. Regional anaesthesia can be used on its own, allowing you to remain conscious but pain-free, or it can be combined with general anaesthesia or sedation to enhance post-operative pain management.
Local Anaesthesia
Local anaesthesia is typically administered by the surgeon to numb a small, specific area of the body where the procedure is being performed. It is commonly used for operations on the teeth, skin, eyes, and digits. Local anaesthesia can be applied using drops, sprays, ointments, or injections and generally does not require the presence of an anaesthetist unless intravenous sedation is needed.
Sedation
Sedation involves administering small amounts of anaesthetic drugs to create a ‘sleep-like’ state. There are varying levels of sedation, but it typically makes you feel drowsy and relaxed about the procedure. You may drift in and out of sleep, and while the clinician administering your sedation may speak with you, you may remain partially aware at times. Sedation is often combined with regional or local anaesthesia to enhance comfort during certain procedures.
