2 DRY WEIGHT GAIN AND INCIDENCE OF INTRADIALYTIC HYPERTENSION: A CROSS-SECTIONAL STUDY IN RURAL HOSPITAL

Abstract

Background: Intradialytic hypertension (HID) is defined as an increase in post-dialysis systolic blood pressure with a post-dialysis and pre-dialysis difference of Systolic Blood Pressure (SBP) ≥ 10 mmHg. HID affects up to 15% of hemodialysis patients and occurs more frequently in older patients, have a lower dry weight, take antihypertensive drugs, and have lower serum creatinine values. It was known to be related to increased morbidity and mortality. To prevent HID, the identification of other risk factors was crucial. Current study aims to determine the relationship between dry weight gain and the incidence of intradialytic hypertension. Methods: This research method was a cross-sectional study. The study was taken on December 2021 at Hemodialysis Unit of Arga Makmur Regional Hospital, North Bengkulu Regency, Bengkulu. Result: There was 27.7% subject having intradialytic hypertension among 54 subjects. The variables consist of gender, age, and etiology did not show any statistically significant relationship toward increased dry weight and the incidence of intradialytic hypertension. Chi-Square test results was p>0.005. The paired t-test showed a significant difference among dry weight, systolic and diastolic blood pressure before and after hemodialysis, with p-value = 0.000 (p <0.005). Increased dry weight gain more than 1 kg was related to 1.7 (95%CI 1.3-2.1) times increased risk of intradialytic hypertension among patients undergoing hemodialysis. Conclusion: The dry weight gain had a statistically significant relationship to the incidence of intradialytic hypertension.
