The word tumescent means swollen and firm. By injecting a large volume of very dilute lidocaine (local anesthetic) and epinephrine (capillary constrictor) into subcutaneous fat, the targeted tissue becomes swollen and firm, or tumescent. The tumescent liposuction technique is a method that provides local anaesthesia to large volumes of subcutaneous fat and thus permits liposuction totally by local anaesthesia. The tumescent liposuction technique eliminates both the need for general anaesthesia and need for IV narcotics and sedatives. The tumescent technique for liposuction
- Provides local anaesthesia,
- Constricts capillaries and prevents surgical blood loss
- Provides fluid to the body by subcutaneous injection so that no IV fluids are needed.
