Tumescent technique for local anesthesia improves safety in large-volume liposuction.

چکیده
The tumescent technique for local anesthesia improves the safety of large-volume liposuction ( > or = 1500 ml of fat) by virtually eliminating surgical blood loss and by completely eliminating the risks of general anesthesia. Results of two prospective studies of large-volume liposuction using the tumescent technique are reported. In 112 patients, the mean lidocaine dosage was 33.3 mg/kg, the mean volume of aspirated material was 2657 ml, and the mean volume of supernatant fat was 1945 ml. The mean volume of whole blood aspirated by liposuction was 18.5 ml. For each 1000 ml of fat removed, 9.7 ml of whole blood was suctioned. In 31 large-volume liposuction patients treated in 1991, the mean difference between preoperative and 1-week postoperative hematocrits was -1.9 percent. The last 87 patients received no parenteral sedation. In a second study, a 75-kg woman received 35 mg/kg of lidocaine on two separate occasions, first without liposuction and 25 days later with liposuction; peak plasma lidocaine concentrations occurred at 14 and 11 hours after beginning the infiltration and were 2.37 and 1.86 micrograms/ml, respectively.

Tumescent technique for regional anesthesia permits lidocaine doses of 35 mg/kg for liposuction.
The tumescent technique for local anesthesia permits regional local anesthesia of the skin and subcutaneous tissues by direct infiltration. The tumescent technique uses large volumes of a dilute anesthetic solution to produce swelling and firmness of targeted areas. This investigation examines the absorption pharmacokinetics of dilute solutions of lidocaine (0.1% or 0.05%) and epinephrine (1:1,...

Using the tumescent technique, liposuction can remove large volumes of fat with minimal blood loss. A maximal safe dosage of dilute lidocaine using the tumescent technique is estimated to be 35 mg/kg. The slow infiltration of a local anesthetic solution of lidocaine and epinephrine minimizes the rate of systemic absorption and reduces the potential for toxicity. Dilution of lidocaine (0.05% of ...
متن کاملThe Tumescent Technique for Liposuction Surgery
The tumescent technique of liposuction is a modification of the wet technique. A large volume of very dilute epinephrine is infiltrated into a targeted fat compartment prior to liposuction, producing a swelling and firmness. This tumescence of fat permits an increased accuracy in liposuction and minimizes postsurgical irregularities or rippling of the skin. Epinephrineinduced vasoconstriction m...

T umescent local anesthesia was first described by Klein in 1987 when he detailed the infiltration of large volumes of a diluted solution of lidocaine with epinephrine into fat before liposuction. The tumescent technique revolutionized liposuction by eliminating the necessity of general anesthesia or intravenous sedation and the copious bleeding that had been associated with liposuction procedu...

BACKGROUND Many surgeons consider liposuction using tumescent local anesthesia (TLA) to be a safe technique, but when TLA has been combined with other techniques, such as general anesthesia or intravenous medication, or when the guidelines associated with TLA have been violated, serious complications and deaths have occurred. This has resulted in uncertainty concerning the safety of liposuction...
