Abstract
Uniform saturation of subcutaneous fat using the “wetting solution” formula described by Klein for his “tumescent technique” has been shown to decrease operative blood loss associated with liposuction procedures and to eliminate the requirement for general anesthesia for selected patients. However, we found this infusate provided an inadequate level of anesthesia for many of our patients. We use preoperative infusion of Klein's epinephrine and lidocaine containing wetting solution in our lipoplasty practice only for control of blood loss and postoperative pain. Our anesthetic of choice for liposuction is the epidural block technique, which provides consistent intraoperative comfort for the patient. We report our experience with 85 consecutive lipoplasty patients who underwent liposuction under epidural anesthesia after subcutaneous fat perfusion with Klein's wetting solution. Our epidural block technique uses the rapidly metabolized local anesthetic agent, chloroprocaine, which has the lowest systemic toxicity risk of any local anesthetic agent. Chloroprocaine's anesthetic characteristics are particularly well suited for the outpatient surgery patient with few undesirable side effects. (Plast. Reconstr. Surg. 100: 1867, 1997.)
