摘　　要：目的分析老年维持性血液透析病人透析中发生低血压的危险因素。方法回顾性分析东南大学附属中大医院江北院区血液净化中心2022年6月至2023年6月老年透析病人的临床资料,包括一般资料、透析中低血压发生情况、临床相关实验室指标。应用Logistic回归分析血液透析中低血压的相关危险因素,绘制ROC曲线探讨相关因素预测低血压发生的效能。结果共纳入128例老年病人,共计透析8766例次,其中52例老年病人共计发生了682例次透析中低血压,发生率为7.78%。根据有无发生透析中低血压分为透析中低血压组和未发生组,Logistic回归分析显示,血管通路方式为长期导管(OR=7.94,95%CI:2.76~22.87,P<0.001)以及超滤速率>8.8 mL/min(OR=5.40,95%CI:1.55~18.75,P=0.008)是透析中发生低血压的危险因素。ROC曲线分析显示超滤速率预测透析中发生低血压的曲线下面积(AUC)为0.712,约登指数为0.357,最佳截断值为9.0 mL/min,灵敏度为67.3%,特异度为68.4%。结论血管通路为长期导管、超滤速率>8.8 mL/min是老年透析病人透析中发生低血压的危险因素,超滤速率对老年病人透析中发生低血压具有一定的预测价值。Objective To analyze the risk factors for the occurrence of intra-dialytic hypotension(IDH)in the elderly patients undergoing maintenance hemodialysis(MHD).Methods The clinical data of the elderly MHD patients in Blood Purification Center of Zhongda Hospital Southeast University from June 2022 to June 2023 were retrospectively collected and analyzed,including general data,incidence of dialysis-related hypotension and laboratory indicators.Logistic regression was used to analyze hypotension-related risk factors in hemodialysis,and ROC curve was drawn to explore the predictive value of hypotension-related factors.Results A total of 128 elderly patients were enrolled,of which 52 elderly patients presented with a total of 682 times of IDH,with an incidence rate of 7.78%.According to the occurence of IDH,all the patients were divided into IDH group and non-IDH group,and Logistic regression analysis showed that long-term catheter(intra-arteriovenous fistula as reference,OR=7.94,95%CI:2.76-22.87,P<0.001),ultrafiltration rate>8.8 mL/min(≤8.8 mL/min as reference,OR=5.40,95%CI:1.55-18.75,P=0.008)were independently associated with IDH.ROC curve analysis showed that the area under the curve(AUC)of the ultrafiltration rate predicting IDH was 0.712,Youden index was 0.357,the optimal cut-off value was 9.0 mL/min,the sensitivity was 67.3%and the specificity was 68.4%.Conclusions Long-term catheter access and ultrafiltration rate>8.8 mL/min are risk factors for IDH in the elderly MHD patients.Ultrafiltration rate has certain predictive value for IDH in elderly MHD patients.
