The word tumescent means swollen and firm.
The tumescent technique for local anesthesia involves the injection of large volumes of very dilute lidocaine (local anesthetic) and epinephrine (drug that shrinks capillaries) into subcutaneous fat. The word tumescent means swollen and firm. With the tumescent technique, the volume of dilute lidocaine that is injected into fat is so large that the targeted areas literally become tumescent (swollen and firm). The tumescent technique produces profound and long-lasting local anesthesia of the skin and subcutaneous fat. Tumescent liposuction designates a form of liposuction that uses tumescent local anesthesia.
The word tumescent refers to anything that is swollen and firm. In the tumescent technique for liposuction, a large volume of very dilute solution of local anesthesia (lidocaine and epinephrine) is infiltrated (injected) into the fat beneath the skin, causing the targeted area to become tumescent, in other words, swollen and firm. The local anesthetic lidocaine in the tumescent solution provides such complete local anesthesia, that it eliminates the need for general anesthesia, or IV sedation. The drug epinephrine (adrenalin) provides profound localized vasoconstriction that it virtually eliminates surgical bleeding during tumescent liposuction. By eliminating the risks of general anesthesia and the risks of excessive surgical bleeding, the tumescent technique for liposuction totally by local anesthesia has eliminated the greatest dangers associated with the older forms of liposuction.
Local anesthesia used in the tumescent technique for liposuction is so effective that patients no longer need intravenous sedatives, narcotic analgesics, or general anesthesia. As a result of the widespread capillary constriction caused by the epinephrine in the anesthetic solution, there is minimal bleeding during and after surgery. This is a major improvement in the liposuction technique compared to the older methods that simply use general anesthesia.
Liposuction was initially developed in 1978-1982 in Italy and France, and introduced into the United States in 1982. At that time, liposuction could only be performed under general anesthesia, and was associated with so much blood loss that patients frequently required hospitalization and blood transfusions. In 1985, Dr. Jeffrey A. Klein, M.D., a dermatologist in California, revolutionized liposuction surgery when he developed the tumescent technique, which permits liposuction totally by local anesthesia and virtually eliminates surgical blood loss. Dr. Klein first presented the tumescent technique at a medical meeting in Philadelphia in 1986. The first publication describing the technique was published in the American Journal of Cosmetic Surgery in 1987. Because the tumescent technique is by far the safest form of liposuction, it has become the world wide standard of care. Not only has the tumescent technique proven to be safer than the older techniques that required general anesthesia, it has also proven to be less painful, has minimized post-operative recovery time, and has produced optimal cosmetic results.
The tumescent technique is so effective at minimizing blood loss that the majority of patients lose approximately 15 to 30 ml (1 to 2 tablespoons) of blood during large volume liposuction. This is the same volume of blood that is taken for routine pre-operative laboratory studies. In the days before the advent of the tumescent technique, the biggest risk of liposuction was excessive loss of blood during surgery. In fact, many surgeons required their patients to donate their own blood several weeks before surgery, and then during surgery, the blood would be returned to the patient by transfusion. With the advent of the tumescent technique, blood transfusions are no longer a part of liposuction surgery.
There is dramatically less bruising with tumescent liposuction totally by local anesthesia compared to other liposuction techniques under general anesthesia. There are two reasons for this significant decrease in bruising. First, because there is so little blood loss with the tumescent technique, there is almost no blood that remains beneath the skin to cause bruising after surgery. The second reason for decreased bruising is that with the tumescent technique there is a considerable amount of post-operative drainage of the blood tinged anesthetic solution. The incisions are so small (about 1.5 mm), the incisions do not require stitches. By allowing these wounds to remain open for two to three days after the surgery, most of the residual blood-tinged anesthetic solution drains out. This minimizes bruising and swelling and accelerates the rate of healing.
No. There have been no reported deaths associated with tumescent liposuction totally by local anesthesia. Virtually all deaths associated with liposuction have been associated with 1) multiple unrelated surgical procedures performed on the same day (facelift, breast augmentation, hysterectomy, etc), 2) excessive amounts of liposuction or an excessive number of body areas treated by liposuction on a single day, 3) the use of general anesthesia or heavy IV sedation with narcotics. Liposuction is an extremely safe procedure provided the patient is not exposed to excessive surgical trauma, excessive narcotic analgesics, or prolonged use of general anesthesia.
