深静脉血栓(DVT)和肺栓塞(PE)是创伤病人死亡的二个潜在因素.但DVT和非致命PE发作的临床症状不典型,早期诊断困难,因而其发生率目前尚不清楚.据权威估计,复合创伤病人DVT的发生率约为20%,故建议采取预防措施.但迄今为止,仍无安全有效的方法.作者就复合创伤后血拴形成及其预防进行了研究.复合创伤病人113例,随机分成二组,分别用连续捆绑加压装置(SCD,共76例)及小剂量肝素皮下注射(LDH,共37例)来预防DVT和PE;并用B超定期监测股静脉血流.对于不明原因的去O_2饱和血症或临床怀疑有PE可能时,监测SPO_2并行通气/灌注肺扫描或肺血管造影检查.当证实有DVT或PE时,立即用肝素治疗.113例复合创伤病人,平均年龄38±18岁,多数病人合并骨折.共发现12例(10%)血栓栓塞,其中5例为下肢DVT,4例为PE但无DVT,3例同时有DVT
Deep vein thrombosis (DVT) and pulmonary embolism (PE) are two potential causes of death in trauma patients, but the clinical manifestations of DVT and non-fatal PE episodes are not typical and are difficult to diagnose early and the incidence is therefore unknown Estimated that the incidence of DVT in patients with trauma was about 20%, so it is recommended to take preventive measures.But so far, there is no safe and effective method.The authors studied the formation and prevention of tethered blood vessels after trauma.CTS patients 113 Cases were randomly divided into two groups. Consecutive bundled pressure devices (SCD, a total of 76 cases) and low-dose heparin subcutaneously (LDH, a total of 37 cases) were used to prevent DVT and PE. The femoral vein blood flow was regularly monitored by B ultrasound. For unexplained O_2 hypernatremia or clinical suspicion of PE may be monitored SPO_2 parallel ventilation / perfusion lung scan or pulmonary angiography, when confirmed with DVT or PE, immediately treated with heparin in 113 cases of trauma patients, The mean age was 38 ± 18 years old and most patients had fractures.There were 12 cases (10%) of thromboembolism, of which 5 were DVT of the lower extremity, 4 were PE but no DVT, 3 were DVT
