Abstract
Background
In large-volume liposuction procedures, one of the most important limitations of total lipoaspirate volume is blood loss. In this study, we aimed to determine the amount of blood loss in individuals who underwent a third-generation internal ultrasound-assisted liposuction (UAL).
Methods
Eleven female and eleven male participants with a mean age of 35.31 (range 20–47) were included in this prospective study. The third-generation internal UAL was performed on multiple anatomical regions using the VASER® Internal Ultrasound Device (Sound Surgical Technologies; Louisville, CO). The demographic characteristics of the participants, the amount of aspirate collected, and hemoglobin (Hgb) and hematocrit (Htc) values before and after the third-generation internal UAL were evaluated.
Results
The mean third-generation internal UAL time was 74.81 ± 17.95 minutes, and the mean aspiration amount was 5,122.27 ± 1,597.43 ml. The aspirated amount was 6.64% ± 2.20 of body weight. The mean Hgb value was 13.87 ± 1.99 before the third-generation internal UAL and 11.26 ± 2.16 (g/dL) after the third-generation internal UAL (z = 4.108, p < 0.001). The mean reduction in Hgb levels with the third-generation internal UAL was 2.61 ± 1.73 and 0.53 ± 0.36 per liter of aspirate taken. The mean Htc value after the third-generation internal UAL was 33.91 ± 6.03 and was significantly lower than the mean Htc value before the third-generation internal UAL, 41.39 ± 5.13 (z = −3.946, p < 0.001). The mean reduction in Htc with the third-generation internal UAL was 7.48 ± 5.42, and the Htc value decreased by 1.50 ± 1.13 per liter of aspirate ingested. The amount of aspirated supernatant was responsible for 44.4% of the change in Hgb and 30.9% of the change in Htc after the third-generation internal UAL.
Conclusion
Knowing the reduction rates in Hgb and Htc with the third-generation internal UAL is useful to plan the amount of aspirate to be taken, the amount of blood loss that may occur with the third-generation internal UAL, and the postoperative care of the patients.
