<unk>  is a surgical technique for delivery of local<unk> . It also makes the target tissue firm and turgid from absorbed water, which can aid certain procedures. It was originally devised for use in liposuction, but has since been applied to other surgical situations, including plastic surgery, burn care, and vascular surgery. It is a relatively safe way to achieve extensive regional<unk>  of skin and subcutaneous tissue with a high total dose but a low risk of systemic toxicity. The subcutaneous infiltration of a large volume of very dilute lidocaine and epinephrine causes the targeted tissue to become swollen and firm, or<unk> , and permits otherwise painful procedures to be performed on patients without subjecting them to the inherent risks of general<unk> , and with reduced blood loss due to the vasoconstriction induced by epinephrine. __TOC__
