目的:研究维持性血液透析(MHD)患者低血压发生的主要风险因素,力求预防透析中低血压(IDH)的发生。方法:根据2012年9月-2015年10月本院血液净化中心95例MHD患者资料。观察单位时间内每次IDH的发生情况,根据IDH的频率将其分为透析中低血压频发组(f-IDH)、透析中低血压偶发组(o-IDH)和无透析中低血压组(no-IDH)。回归分析各指标与IDH发生的联系。结果:IDH的发病率38.7%,其中o-IDH为27.1%,f-IDH为12.3%。多因素Logi Sti C回归分析结果显示:血NT-pro BNP、年龄、血浆白蛋白、超滤率等指标与IDH的发生有密切关系(P<0.05)。结论:MHD患者诱发IDH主要风险因素有:血NT-pro BNP水平高、高龄、低血浆白蛋白、高超滤率等。
Objective: To study the main risk factors of hypotension in maintenance hemodialysis (MHD) patients and to prevent the occurrence of hypotension (IDH) in dialysis patients. Methods: According to the data of 95 MHD patients in our hospital from September 2012 to October 2015. According to the frequency of IDH, IDH was divided into three groups: IDH (f-IDH), o-IDH (dialysis-free) and dialysis-free hypotension (no-IDH). Regression analysis of the various indicators and the occurrence of IDH. Results: The incidence of IDH was 38.7%, of which o-IDH was 27.1% and f-IDH was 12.3%. Logistic regression analysis showed that there was a close relationship between serum NT-pro BNP, age, serum albumin and ultrafiltration rate and IDH (P <0.05). Conclusions: The main risk factors for IDH induced by MHD are as follows: high blood NT-pro BNP level, advanced age, low serum albumin, high ultrafiltration rate and so on.
