Abstract:
Objective:To explore the safety and clinical effects of extensive and large-volume liposuction.Methods:From October 2011 to June 2021 in the Department of Plastic and Reconstructive Surgery, Shanghai 9th People’s Hospital, Shanghai Jiao Tong University School of Medicine, patients receiving liposuction exceeding 15% of the body surface area and/or volume of aspirate exceeding 5 liters in a single operative session were retrospectively reviewed. All patients received liposculpture procedure under general anesthesia plus sequential infiltration of 0.025 2% low-concentration lidocaine tumescent solution. The total volume of tumescent solution injected, total volume of aspirates, volume of aspirated fat and fluid, complications as well as patient satisfaction were analyzed.Results:A total of 313 patients, 5 males and 308 females, were included in the study. The average age was 30.6±8.2 years and average body mass index was 23.9±3.5 kg/m 2. A total of 360 operations were performed. Among them, 271 cases underwent 1 operation, 37 cases underwent 2 operations, and 5 cases underwent 3 operations. The tumescent fluid volume was (8 741.6±1 559.8) ml with the maximum usage of lidocaine of 3 200 mg. The aspirates volume was (6 582.4±1 515.0) ml, of which the volume of supranatant fat and infranatant fluid were (3 662.1±1 230.8) ml and (2 936.0±765.4) ml, respectively. The ratio of infiltrate to aspirate was 1.37±0.23. Aspirate volume exceeded 10.00 L in 13 operations (3.61%), ranged from 7.50 to 9.99 L in 73 operations (20.28%), 5.00 to 7.49 L in 259 operations (71.94%) and less than 5.00 L in 15 operations (4.17%). Except for one patient (0.28%) receiving transfusion of red blood cell suspension due to postoperative anemia, no severe complications were observed. There were 10 cases (2.78%) of minor complications, including mild irregularities (5 cases), local seromas (2 cases), poor incision healing or scar hyperplasia (2 cases) and mild pigmentation caused by skin burn during radiofrequency skin tightening (1 case). The satisfaction rate of the patients was 97.2% (350/360). Conclusions:The results of this study indicate that large volume and extensive liposuction are safe. The satisfaction of the patients is very high. Sequential infiltration of tumescent solution with 0.025 2% low-concentration of lidocaine tumescent solution is safe in reducing the risk of lidocaine toxicity.
