This study was performed in 15 female patients submitted to suction lipectomy as an isolated procedure, to establish blood loss in the procedure. A wide variation of blood-to-fat ratios was observed (17 to 59%) with a mean blood loss in lipoaspirates of 34 +/- 3%. Internal blood losses occurring in the first 72 post-operative hours were as important as or more important than external losses, and responsible for a mean 7% fall in the level of hemoglobin. Internal blood losses occurred between 72 hours and the 7th to the 10th post-operative days and were responsible for a mean 3% fall in the level of hemoglobin. Blood losses occurring in this study were demonstrated to be greater than usually assumed. Some prophylactic measures are recommended to provide for a safer treatment of these patients: an iron supplementation during the pre-operative period; careful clinical and laboratorial screening for bleeding disorders and for the intake of drugs that can interfere with coagulation; use of smaller-diameter cannulas for aspiration, auto-transfusion when aspirating in excess of 1,000 ml, and limiting the aspiration to 1,500 ml.
本研究对15名接受单纯吸脂术的女性患者进行，以确定该手术中的失血量。观察到血液与脂肪比例差异很大（17%至59%），吸脂物中的平均失血量为34±3%。术后头72小时内发生的内出血与外出血同样重要或更重要，导致血红蛋白水平平均下降7%。内出血发生在术后72小时至第7至10天，导致血红蛋白水平平均下降3%。本研究中发生的失血量被证明比通常认为的要多。建议采取一些预防措施，以便更安全地治疗这些患者：术前补充铁剂；仔细进行临床和实验室筛查，以排查出血性疾病以及是否服用了可能干扰凝血的药物；使用较小直径的套管进行抽吸，抽吸超过1000毫升时进行自体输血，并将抽吸量限制在1500毫升。
