| 摘 要： | 目的探讨老年股骨颈骨折病人术后发生下肢深静脉血栓(LDVT)的危险因素。方法回顾性分析因股骨颈骨折行手术治疗的老年病人病历资料，分别使用单因素和logistic回归多因素分析术后发生LDVT的独立危险因素，并建立相关预测模型。结果体质量指数≥24 kg/m2、糖尿病、总胆固醇>5.69 mmol/L、三酰甘油>1.8 mmol/L、手术时间≥60 min、静吸复合麻醉及手术等待时间≥5 d是老年股骨颈骨折病人术后发生LDVT的独立危险因素(P < 0.05~P < 0.01)。预测老年股骨颈骨折病人术后发生LDVT的模型验证结果显示，H-L偏差度检验结果为χ2=3.71，P>0.05，C-index指数为0.904(95%CI:0.869~0.939)，说明列线图预测模型具有良好的精准度和区分度。结论老年股骨颈骨折病人术后发生LDVT的独立危险因素显示，建立的预测模型具有准确的预测能力和区分度，临床应用价值较高。

| Abstract: | ObjectiveTo investigate the risk factors of lower extremity deep venous thrombosis(LDVT) in elderly patients with femoral neck fracture after operation.MethodsThe medical records of femoral neck fracture elderly patients treated with surgical treatment were retrospectively analyzed.The independent risk factors of postoperative LDVT were analyzed using the univariate and logistic regression analysis, and the correlation prediction model was established.ResultsThe body mass index ≥24 kg/m2, diabetes mellitus, total cholesterol(TC)>5.69 mmol/L, triacylglycerol(TG) >1.8 mmol/L, operation time ≥60 min, intravenous inhalation combined anesthesia and operation waiting time ≥5 d were the independent risk factor of postoperative LDVT in elderly patients with femoral neck fracture(P < 0.05 to P < 0.01).The results of model verification in predicting postoperative LDVT in elderly patients with femoral neck fracture showed that the results of H-L deviation test were χ2=3.71 and P>0.05, and the C-index was 0.904(95%CI: 0.869-0.939), which indicated that the prediction model of line chart had good accuracy and differentiation.ConclusionsThe independent risk factors of postoperative LDVT in elderly patients with femoral neck fracture.The prediction model has accurate prediction ability and differentiation, and high clinical application value. |
