【摘要】 目的：分析基于Caprini风险评估模型的分级干预联合鼻饲温开水对危重症患者下肢深静脉血栓的预防价值。方法：根据随机数字表法将120例于2020年6月—2023年6月在山东大学齐鲁医院接受治疗的危重症患者分为两组。对照组(n=60)接受常规干预，观察组(n=60)接受基于Caprini风险评估模型的分级干预联合鼻饲温开水干预。对两组血液流变学、凝血指标、下肢深静脉血栓风险分级及下肢深静脉血栓发生率进行比较。结果：干预第7天，两组全血高切黏度、全血低切黏度、血小板聚集率和D-二聚体、凝血酶-抗凝血酶复合物均低于干预前，且观察组均低于对照组，两组凝血酶原时间均长于干预前，且观察组长于对照组，差异均有统计学意义(P<0.05)；干预第7天，观察组下肢深静脉血栓风险分级优于对照组，下肢深静脉血栓发生率低于对照组，差异均有统计学意义(P<0.05)。结论：基于Caprini风险评估模型的分级干预与鼻饲温开水联合应用，可改善危重症患者的血液流变学和凝血功能，有效预防下肢深静脉血栓发生。

    [Abstract] Objective： To analyze the preventive value of graded intervention based on Caprini risk assessment model combined with nasal feeding with warm water on deep vein thrombosis of lower extremity in critical illness patients. Method： A total of 120 critical illness patients treated in Qilu Hospital of Shandong University from June 2020 to June 2023 were divided into two groups according to random number table method. The control group (n=60) received routine intervention ......
