“…Tumescent local anesthesia, a special form of local anesthesia, was first described by Klein [15] in 1987 for liposuction. Breuninger and Wehner-Caroli described a variation of this procedure and called it slow infusion tumescent anesthesia [16] or subcutaneous infusion anesthesia (SIA) [17]. In SIA, a volume-controlled infusion pump is used for achieving a slow and steady penetration of the solution into the adipose tissue.…”
