Local anesthesia for abdominoplasty, liposuction, and combined operations

This article describes a procedure to perform abdominoplasty, liposuction, and combined operations under local anesthesia. With an anesthetic solution composed of 25 cc of 2% lidocaine, 25 cc of 0.5% bupivacaine, 1 cc of epinephrine or ornipresine, and 350 cc of saline solution, a satisfactory dilution with low concentration and lasting effects was obtained. After infiltration a large amount was lost in the incision, the dissection, and the resected dermofatty tissue. A small amount of anesthetic remained in the operated area to be metabolized by the liver. Low lidocaine levels were found in venous blood samples during surgery. This type of anesthesia is advised in minor, limited, and normal abdominoplasties in normal-sized patients, or major abdominoplasties in small patients. In liposuction procedures, it is possible to anesthetize the patient using the same procedure and operate in an equivalent area. As a high proportion of the infiltrated anesthesia was lost during the operation, a similar amount could be used to infiltrate and operate other areas so that an abdominoplasty might be combined with liposuction or mastoplasty. We have experience with 25 abdominoplasties and 21 liposuctions performed under local anesthesia. There were no complications related to local anesthesia and no one had unpleasant memories of intraoperative events.
