【摘要】目的通过对单中心维持性血液透析(maintenance hemodialysis,MHD)患者多个相关性因素进行分析,了解影响血液透析患者长期生存的因素,以期提高MHD 患者的生存率和生存质量。方法回顾分析2010 年1 月~2017 年12 月在山西医科大学第二医院肾内科血液净化中心透析超过3 个月且转归明确的MHD 患者的病历资料,探寻各项指标对MHD 患者生存率的影响。结果共纳入MHD 治疗的终末期肾病患者235 例,其中男性133 例,女性102 例。MHD 患者1 年生存率为93.7%,3 年生存率81.4%,5 年生存率76.2%,10 年生存率16.4%,生存期最长1 例超过252 月。首次透析时高龄、原发病为糖尿病肾病、每周透析频率<2 次/周、透析前高血磷可增加血液透析患者死亡风险(RR 值分别为1.03, 2.24, 2.34, 1.34;P 值分别为<0.001,<0.001,<0.001,0.034),而首次透析血管通路为自体内瘘、尿素清除指数(Kt/V)≥1.2、较高血红蛋白及血白蛋白水平可降低血液透析患者死亡风险(RR 值分别为0.78, 0.72, 0.76, 0.61;P 值分别为<0.001,<0.001,<0.001,<0.001)。结论随着血液透析治疗时间延长,患者的长期生存率逐渐下降。首次血液透析时高龄、原发病为糖尿病肾病、透析前高血磷为透析患者死亡的危险因素,而首次透析血管通路为自体内瘘、透析充分性好、有较高血红蛋白及血白蛋白水平是透析患者预后的保护因素。
