With sedation anaesthesia, also known as twilight anaesthesia, a local anaesthetic is applied to the nose and face regions, and a mixture of sedative agents will be administered.
Dr De Silva only utilises anesthesiologists that specialise in sedation and are highly skilled in giving sedation medications tailored to the individual. This sedative will cause patients to feel very sleepy and relaxed, or possibly even euphoric, but patients will remain conscious and able to answer questions.
Patients often do not remember the procedure itself or a short period after.
This method of anesthesiology is highly preferable to patients who do not want to take the risks of general anaesthesia, as the recovery period of twilight anaesthesia is much shorter and can be a safer alternative.
Dr De Silva has taken the use of sedative anaesthesia from the United States where it is commonly provided to patients to offer them a faster recovery and more pleasant experience.
