Abstract: 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.
