维持性血液透析患者高血压状况分析

摘要

目的 通过对维持性血液透析(MHD)患者血压情况以及MHD患者人群透析前、后血压与年龄、原发病和透析充分性等之间的关系进行分析,探讨MHD患者高血压的相关因素.方法 分析我院118例MHD患者3个月的透析前、后平均血压与每月透析时间、服用降压药物种类、透析年限及尿毒症原发病之间的相关性.不同组问血压水平进行方差分析或t检验.结果 老年组透析前后舒张压显著低于其他年龄组(P<0.05);原发病为糖尿病的MHD患者透析前后舒张压均显著低于慢性肾小球肾炎组和高血压病组(P<0.05);每月透析时间与透析后收缩压存在显著相关性(r=-0.266,P<0.05).结论 充分透析有利于MHD患者高血压的控制,老年和糖尿病MHD患者在透析中更容易发生低血压.%Objective To investigate the relations among blood pressure, age, primary disease and adequacy of hemodialysis in maintenance hemodialysis (MHD) patients, as well as to find out factors on which impact the blood pressure of MHD patients. Methods To select 118 cases of MHD more than 3 months, grouped by age, primary disease, dialytic-hours/month, measure their systolic pressure and diastolic pressure before and after hemodialysis in 1 to 3 months, calculated the average value and analysis relations. Results The pre-dialytic diastolic pressure and post-dialytic diastolic pressure of aged group were significantly lower than those in other age groups (P＜0.05); The pre-dialytic diastolic pressure and post-dialytic diastolic pressure of diabetes group were significantly lower than those in chronic glomerular nephritis group and hypertension group (P＜0.05). There was a significant negative correlation between post-dialytic systolic pressure and dialytic-hours/month (r=-0.266, P＜0.05). Conelusion Adequate hemodialysis will make the blood pressure of maintenance hemodialysis patients better controlled. The aged patients and diabetes patients have a tendency of intradialytic hypotension complication.
