tumescent infiltration
Injection of large volumes of dilute local anesthetic solution into fatty tissue prior to liposuction.
Full Definition
A technique involving the injection of significant volumes of dilute lidocaine and epinephrine solution into subcutaneous fat before liposuction procedures. This infiltration causes the tissue to become swollen and firm (tumescent), which facilitates fat removal while providing anesthesia and hemostasis. The solution typically contains saline, lidocaine for local anesthesia, and epinephrine for vasoconstriction. This method has largely replaced general anesthesia for many liposuction procedures and significantly reduces bleeding and post-operative pain.
Usage
Usage note: Distinguished from 'tumescent technique' which refers to the broader liposuction method.
