摘　　要：目的探讨超声检测积脂血症的关节制动时间。方法实验组：对20支内含新鲜血液与猪骨髓混合液体的试管充分摇匀，即刻应用高频线阵探头进行定区短间隔连续监测。临床组：10例尚能行走的创伤性积脂血症患者在术前行超声定区短间隔连续监测及CT、MR检查。结果实验组：即刻检查，液体呈云雾状回声，并见脂质成分向上缓慢漂浮；2．7～3．7min（平均3．17min）液体呈2层，回声接近，界面模糊；5．3～8．0min（平均6．75min）血清层出现并逐渐增厚，液体呈3层。临床组：超声检查显示液体开始呈云雾状中等回声，2．0～4．0min（平均3．08min）液体呈2层，4．4～10．0min（平均6．92min）血清层开始出现，液体呈3层，以后血清层逐渐增厚。3例见骨折线，2例隐匿性骨折经积脂血症确诊。CT检查10例见骨折线，其中6例髌上囊液体呈3层，4例呈2层；MR检查10例见骨折线，其中7例髌上囊液体呈3层，3例呈2层。结论超声检测积脂血症的最佳关节制动时间可以缩短为10min，必要制动时间2～4min。Objective To investigate the braking time in diagnosis of lipohemarthrosis by ultrasound. Methods Experiment group：After 20 tubes containing fresh blood and pig marrow were uniformly mixed, they were instantly continuously detected by high-frequency linear array transducer in fixed area at short-interval. Clinical group： Ten walking patients with lipohemarthrosis were examined with continuous detection by ultrasound,CT and MR before operation. Results Experiment group： Cloudy echo and slowly floating up of lipoids were detected at the beginning. After 2.7 to 3.7 minutes （average 3.17 minutes）, the liquid was divided into two layers with vague boundary. After 5.3 to 8.0 minutes （average 6.75 minutes） ,the liquid was divided into 3 layers with thickening serum laye. Clinical group： Ultrasound findings： Cloudy medium echo was detected at first. After 2.0 to 4.0 minutes （average 3.08 minutes）,the liquid was divided into two layers. After 4.4 to 10.0 minutes （average 6.92 minutes） , the liquid was divided into 3 layers with thickening serum layers. Three knees showed fracture line and 2 knees with occult fracture were diagnosed as lipohemarthrosis. CT and MR findings： Ten knees showed fracture line in CT examination,of which 7 knees showed double liquid-liquid layer and 3 knees showed single liquid-liquid layer in the suprapatellar bursa. Ten knees showed fracture line in MR examination, 6 knees showed double liquid-liquid layer and 4 knees showed single liquid-liquid layer in the suprapatellar bursa. Conclusions The best braking time in diagnosing lipohemarthrosis by ultrasound can be shorten to 10 minutes and the necessary braking time is 2 to 4 minutes.
