BACKGROUND: Limited dilute lidocaine infiltration facilitates a comfortable procedure and a rapid recovery process following a novel intervention for reduction of cellulite. Infiltration of dilute lidocaine has many other practical applications in dermatologic surgery.
OBJECTIVES: This article describes a safe, effective technique for local infiltration of limited volume dilute lidocaine anesthesia in a cellulite reduction procedure.
METHODS: The limited dilute lidocaine technique was utilized in studies of a novel device designed to reduce the appearance of cellulite by focal release of fibrous septa in a minimally invasive procedure. No sedation was used. A small (27- to 30-gauge) needle was used to deliver anesthesia to the entry sites. Then, a 20-gauge spinal needle was tunneled under the skin in the superficial plane to manually deliver anesthetic along the advancement pathway of the device and marked cellulite targets.
RESULTS: During the initial studies, the mean delivered anesthesia volume was 357.2 ml (range, 250-525 ml) or 18.7 mg/kg (range, 11.1-28.4 mg/kg). The mean anesthesia time was 16 min (range, 8-32 min). The mean number of cellulite depressions treated was 19.8 (range, 11-34). Adverse events were closely monitored, and there were no signs of toxicity in any study patients. There were very low levels of discomfort; all patients reported the procedure was tolerable. This technique facilitates a time-efficient procedure and minimizes weeping of excess fluid during recovery.
CONCLUSIONS: When administered with care and skill, the limited dilute anesthesia technique is a safe, effective approach for local anesthesia with many practical applications in dermatologic surgery.
