神经重症患者下肢深静脉血栓发生现状及其影响因素分析

Study of lower extremity Deep Vein Thrombosis and its related factors in neurocritical patients

目的:调查神经重症患者下肢深静脉血栓(DVT)现状,并分析其影响因素。方法:收集223例神经重症患者的临床资料,采用Logistic回归分析患者发生下肢DVT的危险因素。结果:单因素分析显示≥60岁、长期卧床、D-二聚体增高、左下肢肌力≤3级、GCS评分低、下肢深静脉导管置入是神经重症患者下肢DVT发生的相关因素(P<0.05);Logistic回归分析显示≥60岁、长期卧床、D-二聚体增高是患者下肢DVT发生的危险因素。结论:应重点防控60岁及以上、长期卧床、D-二聚体增高的神经重症患者发生下肢DVT,尽早完善下肢DVT防控的护理策略。

Objective:To explore the status of lower extremity Deep Vein Thrombosis(DVT)and its related factors in neurocritical patients.Methods:The related clinical data of 223 neurocritical patients were collected,and Logistic regression was used to analyze the risk factors of DVT.Results:Univariate analysis showed that age over 60 years,stay in bed for a long time,higher D-dimer,left leg muscle strength level with 3 or less,lower GCS score,central venous catheter placement were related factors(P<0.05)with DVT in lower extremity in neurocritical patients.The Logistic regression analysis showed that age over 60 years,stay in bed for a long time and higher D-dimer were independent risk factors with DVT.Conclusion:Those with the age over 60 years,in bed for a long time and with higher D-dimer were the focus of prevention and control of DVT in neurocritical patients,and the related nursing strategies are needed in the future.
