Analysis on the occurrence and influencing factors of frequent intradialytic hypotension in hemodialysis patients / 中国实用护理杂志

ABSTRACT

0bjective To investigate the occurrence of frequent intradialytic hypotension in hemodialysis patients and Analyzed influencing factors. Methods The 1 933 hemodialysis sections of 156 maintenance hemodialysis patients in the Huashan hospital affiliated to Fudan University in Shanghai were selected, and divided into frequent intradialytic hypotension and non- frequent intradialytic hypotension depending on whether the incidence of intradialytic hypotension is greater than 20%, and the patients' dialysis data and biochemical examination data are collected for the analysis of influencing factors. Results The incidence of frequent IDH in maintenance hemodialysis patients was 62.18%(97/156), and the pre-dialysis blood pressure of frequent IDH patients were higher than non-frequent IDH patients, frequent IDH patients (134.02±21.01)/(73.85±10.73) mmHg(1 mmHg=0.133 kPa), non-frequent IDH patients (124.66 ± 17.89)/(69.32 ± 10.65) mmHg, (t=-2.851,-2.558, P＜0.05), but lower in post-dialysis, frequent IDH patients(114.91±19.21)/(68.38±11.41) mmHg, non-frequent IDH patients (127.90± 20.58)/(74.46±11.79) mmHg, (t=3.989, 3.189, P＜0.01). Binary Logistic regression analysis showed that hemoglobin ( OR=0.354, P=0.015) and high-density lipoprotein ( OR=0.155, P=0.003) were protective factors for the occurrence of frequent IDH, and ultrafiltration volume/weight ( OR=6.021, P=0.002) and N-terminal pro-brain natriuretic peptide ( OR=2.687, P=0.020) were risk factors. Conclusions The incidence of frequent IDH in hemodialysis patients is high, and patients with high filtration rate, high N-terminal pro-brain natriuretic peptide, low hemoglobin and high density lipoprotein should be paid close attention to. It is recommended to regularly monitor patients' biochemical indicators, strengthen blood pressure monitoring for high-risk groups, and timely deal with the symptoms of low blood pressure.
