Tumescent liposuction, also called liposculpture, is a vast improvement over traditional liposuction. The physician "inflates" the patient's fat with a diluted local anesthetic before he/she vacuums it out in a process called suction aspiration. This eliminates risks associated with the general anesthesia used in traditional liposuction.
Another major advantage of the anesthesia used in the tumescent procedure is that it practically eliminates blood loss by constricting (tightening) blood vessels. In traditional liposuction, no such agents are used, with patients sometimes experiencing significant bleeding and even needing blood transfusions.
Tumescent liposculpture also allows the patient to remain awake during the procedure and able to assist the surgeon in gauging the completeness and evenness of fat removal. The patient can actually sit or stand and make side-to-side comparisons. Try that using general anesthesia!
Using the tumescent method, all liposuction cases can be performed entirely with local anesthesia. The treated area can remain numb for up to 24 hours, greatly reducing post-operative discomfort.
