Tumescent Technique
The tumescent technique is a method of local anaesthesia used in liposuction and other procedures involving the subcutaneous fatty tissue. The surgeon introduces large volumes of a highly diluted solution into the tissue. This solution typically contains a local anaesthetic, adrenaline for vasoconstriction, and a saline-based carrier solution. The tissue temporarily swells and becomes firm as a result — which is the origin of the term "tumescent." The method fulfils several functions simultaneously. It anaesthetises the area, reduces bleeding, and facilitates treatment of the fatty tissue. In liposuction, this allows the tissue to be aspirated more gently. Tumescent local anaesthesia is considered an established technique. In aesthetic and dermatological surgery, the technique is used not only for liposuction but also in dermatosurgical procedures and in certain areas of sweat gland surgery. It generally enables a larger operative field to be treated under local anaesthesia. The solution used, the volume infiltrated, and whether the procedure is performed under tumescent local anaesthesia alone or with additional sedation depend on the treatment area and the planned procedure. Swelling, a sensation of tightness, or temporary bruising may occur following the procedure. Experience with the technique, careful dosing, and precise planning of the entire procedure are therefore decisive factors.
