tumescent technique
Pronunciation: too-MESS-ent tek-NEEK
A liposuction method using large volumes of dilute local anesthetic solution to firm and numb tissues while minimizing blood loss.
Full Definition
The tumescent technique is a foundational method in liposuction that involves the infiltration of large volumes of dilute lidocaine and epinephrine solution into the subcutaneous fat layer before fat removal. This solution causes the tissue to become firm and swollen (tumescent), hence the name. The technique provides effective local anesthesia, significant vasoconstriction to minimize bleeding, and hydraulic dissection of fat cells to facilitate removal. The standard tumescent solution contains lidocaine for anesthesia, epinephrine for vasoconstriction, and sodium bicarbonate to reduce injection discomfort, all diluted in normal saline. This approach has revolutionized liposuction safety by dramatically reducing blood loss and allowing procedures to be performed under local anesthesia with improved patient comfort and reduced complications.
Usage
Usage note: Document solution concentration and total volume administered for safety monitoring.
