Frequency of Intradialytic Hypertension among Maintenance Hemodialysis Patients: A Single Centre Study

Introduction: Chronic kidney disease is a public health problem around the world. Worldwide, most patients with end-stage renal disease (ESRD) who can access renal replacement therapy are receiving hemodialysis (HD).Hemodialysis is not a smooth process. It has several complications; intradialytic hypertension (IDH) is one of them.The aim of the study was to determine the frequency of intradialytic hypertension among hemodialysis patients. Methods: This prospective observational study was conducted at the National Institute of kidney diseases and urology, Dhaka, Bangladesh from November 2021 to April 2022. A total of 249 patients were included in the study. A convenient purposive sampling method was used. Results: Only 5(2%) patients received HD whose age was less than 20 and 28 (11.2%) patients were aged more than 60 years of age. Half of the patients were female (127, 51%) and half of the patients were male. Only 15 patients (6%) population had Intra dialytic HTN. Pre-Dialytic, Post-Dialytic, and Intra- dialytic mean blood pressure was 102.78±SD, 62±SD, and 81.74±SD, respectively. Mean ultrafiltration during dialysis was 2789±SD. Mean blood flow during dialysis was 235.17±SD. The relationship between IDH and ultrafiltration and IDH and weight change was weak, positive and insignificant. The relationship between Intradialytic HTN and blood flow was weak, negative and insignificant. Conclusion: Intradialytic hypertension is the most important hemodialysis difficulty observed in our country with a higher risk found in subjects with higher weight gain and higher ultrafiltration attentiveness.
