Tumescent technique is used for almost all liposuction, and has been for a quite some time. 'Tumescent technique' essentially means that a saline solution containing epinephrine (and usually a local anesthetic such as lidocaine) is injected into the areas to be suctioned, so that the blood vessels in the fat constrict prior to the passage of the liposuction cannula.
The vasoconstriction produced by the epinephrine solution minimizes bleeding during fat removal, and liposuction of a large volume of fat can be performed without significant blood loss.
Occasionally I see advertisements for 'tumescent liposuction', which always seems rather odd. Advertising that one performs 'tumescent liposuction' (as opposed to some other, unnamed kind of liposuction, I guess) is a little like bragging that you drive a car with wheels.
