ICU患者下肢深静脉血栓形成的原因分析及对策

Factor analysis and treatment of deep venous thrombosis in ICU patients

目的探讨我院ICU患者发生下肢深静脉血栓(DVT)的形成原因及治疗对策。方法调查医院收治的ICU患者中,分析下肢深静脉血栓的发生与原发症的关系,并以此为依据制定预防措施。结果 247例ICU患者发生DVT发生42例,发病率为17.01%;年龄>60岁(P<0.01),脑卒中(P<0.05),骨关节置换术后(P<0.05),机械通气的时间≥72h(P<0.05)为DVT发生高危险因素。结论 ICU患者存在多种增加下肢深静脉血栓发生率的危险因素,提高医护人员对下肢深静脉血栓形成机制的认识。有针对性制定预防措施可以减少ICU患者下肢深静脉血栓的发生。

[Objective]To analyze the factors and treatment of deep venous thrombosis in intense care patients. [Methods]Clinical data of 57 cases of DVT were analyzed in ICU patients respectively, six high risk factors of these patients were analyzed using univariate logistic regress analysis.[Results]The overall DVT incidence rate was 17.01%（42/247）. Age （ 60 years）, stoke, arthroplasty and mechanical ventilation time （72 h） were the major high risk factors of deep venous thrombosis incidence. [Conclusions]Many ICU patients with related high-risk factors may influence DVT. Early prophylaxis, early diagnosis and treatment will decrease extremity deep venous thrombosis.
