We will put you in a state of controlled unconsciousness which will make you unaware of your surroundings. This is done with the aid of injected medication or inhaled gasses or a combination thereof.
These agents inhibit feeling, nerve conduction and movement at the level of the brain and the nerves.
Often called “local”.
Parts of your body are numbed to prevent you from feeling anything in a certain body part or moving it.
This can be used as a sole method of anaesthesia. It can also be used in conjunction with general anaesthesia. In either case, it will aid you with post-operative pain relief.
i. Regional anaesthesia
Neuraxial blocks: Local anaestetic is injected into your lower back and will not only numb your lower body, but temporarily paralyze your lower body e.g.:
Peripheral nerve blocks: Local anaesthetic is injected around one or a group of nerves, making a limb or a part of a limb numb and temporarily paralyzed. This could range from a whole limb to as little as a single finger or toe.
ii. Local infiltration: Local anaesthetic is injected into the operation site to minimise pain and cause numbness.
Drugs and gasses are used to make you drowsy yet rousable.
Sedation is often combined with some form of local anaesthesia.
Eye surgery (cataract removal) and large joint replacements are often done with a local anaestesia/sedation combination.
Endoscopic investigation of your stomach and bowel are predominantly done under sedation alone.
