Tumescent anaesthesia is a type of local anaesthesia that involves the injection of a large amount of diluted local anaesthetic solution into the area to be treated. The purpose of tumescent anaesthesia is to numb the area and make it easier for the doctor to perform the procedure. Synonyms for tumescent anaesthesia include swollen anaesthesia, puffy anaesthesia, bloated anaesthesia, and distended anaesthesia. These synonyms are used to describe the same medical procedure but use different words to convey the idea of the local anaesthetic solution causing swelling or puffiness in the treated area. Tumescent anaesthesia is commonly used in cosmetic surgery procedures and is often preferred over general anaesthesia due to its lower risk of complications.
