Lipoplasty remains the most common cosmetic surgical procedure performed in the United States. In spite of its well documented clinical advantages, ultrasound-assisted lipoplasty (UAL) accounts for less than 20% of all lipoplasty procedures currently performed.
The purpose of this study is to determine the blood content of third-generation internal UAL aspirate and compare it to traditional lipoplasty aspirate.
The lipoplasty aspirate of 27 consecutive patients who underwent traditional suction-assisted lipoplasty (SAL) of their back and posterior flanks was compared to the aspirate of 30 consecutive patients who underwent third-generation internal UAL of their backs and posterior flanks using the VASER Internal Ultrasound Device (Sound Surgical Technologies; Louisville, CO). The volume and composition of the wetting solution used was the same for both groups. The aspirate analysis was performed by an independent laboratory on a Beckman Coulter LH 750 blood analyzer (Fullerton, CA) and consisted of complete blood counts after separation of the fat.
The hemoglobin content of SAL aspirate was 7.5 times greater than in the aspirate. The hematocrit value of SAL aspirate was 6.5 times greater than in the VASER-assisted lipoplasty aspirate. Statistical analysis using an independent t test confirmed that the data was statistically significant with P values of < .0001 for both hemoglobin content and hematocrit values.
We conclude that third-generation internal UAL should be considered for patients undergoing large-volume lipoplasty procedures or lipoplasty of tight, fibrous areas, such as the back and posterior flanks, where increased blood loss is expected.
脂肪抽吸术仍是美国最常见的整形手术。尽管其临床优势已得到充分证明，但超声辅助脂肪抽吸术（UAL）在目前所有脂肪抽吸手术中所占比例不到20%。
本研究的目的是确定第三代体内UAL吸出物的血液含量，并将其与传统脂肪抽吸吸出物进行比较。
将27例连续接受背部和后腰部传统吸脂辅助脂肪抽吸术（SAL）患者的脂肪抽吸吸出物，与30例连续接受使用VASER体内超声设备（Sound Surgical Technologies；科罗拉多州路易斯维尔）进行背部和后腰部第三代体内UAL患者的吸出物进行比较。两组使用的湿润溶液的体积和成分相同。吸出物分析由一个独立实验室在贝克曼库尔特LH 750血液分析仪（加利福尼亚州富勒顿）上进行，包括脂肪分离后的全血细胞计数。
SAL吸出物的血红蛋白含量比UAL吸出物高7.5倍。SAL吸出物的血细胞比容值比VASER辅助脂肪抽吸吸出物高6.5倍。使用独立t检验的统计分析证实，血红蛋白含量和血细胞比容值的数据在统计学上具有显著性，P值均<0.0001。
我们得出结论，对于接受大容量脂肪抽吸手术或在预计失血增加的紧密、纤维区域（如背部和后腰部）进行脂肪抽吸的患者，应考虑使用第三代体内UAL技术。
