摘要目的 观察脂肪抽吸术中肿胀麻醉液在皮下留置时间及温度对出血量的影响.方法 对20例美容就医患者进行脂肪抽吸术,其中10例行双上臂脂肪抽吸,另10例行双大腿脂肪抽吸,分别计算肿胀麻醉液于皮下留置不同时间和不同温度时的手术出血量.结果 20例术后出血量在21.42～77.26 ml,平均为(50.27±18.56) ml.其中肿胀麻醉液在右上臂皮下留置0.5h后进行脂肪抽吸,平均出血量为(19.89±7.52) ml,肿胀麻醉液注射完毕左上臂即行脂肪抽吸,平均出血量为(26.25±12.07) ml；右下肢使用加热至37℃的肿胀麻醉液,平均出血量为(28.60±6.07) ml,左下肢使用未加热的肿胀麻醉液(23℃),平均出血量为(29.93±9.06) ml.结论 肿胀麻醉液注射完成后留置0.5h可有效降低手术出血量.使用加热至37℃的肿胀麻醉液不增加术中出血量.

abstractsObjective To assess effects of the different retention time and temperature of the tumescent fluid on surgical blood loss in tumescent liposuction.Methods 20 patients with localized fat deposits received tumescent liposuction and the blood loss were calculated and compared between two treated groups.Results The mean surgical blood loss in 20 patients was (50.27± 18.56) ml with range (21.42-77.26) ml.The blood loss in liposuction with 0.5 hour retention and no retention of tumescent fluids was (19.89±7.52) ml and (26.25±12.07) ml,respectively; the blood loss in liposuction with heated (37℃) and non-heated tumescent fluid (23℃) was (28.60±6.07) ml and (29.93±9.06) ml,respectively.Conclusions A half hour retention of tumescent fluid in subcutaneous tissue after injection could reduce the surgical blood loss and the blood loss amount does not increase in the usage of a pre-heated tumescent fluid.
