Blood pressure variation and its correlates among patients undergoing hemodialysis for renal failure in Benin City, Nigeria
Abstract
Background: Blood pressure (BP) variation is commonly encountered during hemodialysis (HD) procedure. Both intradialysis hypotension and hypertension have implications for outcome of treatment and overall morbidity and mortality of the patients.
Methodology: A retrospective study was carried out in the dialysis unit of a tertiary health institution in Benin City among patients who had HD for acute kidney injury (AKI) or chronic kidney disease (CKD) over a 3-year period. Data retrieved included age, gender, type of kidney disease, cause of kidney disease, systolic BP at onset of dialysis and at end of dialysis, and diastolic BP (DBP) at onset of and at end of dialysis.
Results: Complete data were available for 217 patients. One hundred and seven patients (49.3%) had no significant change in BP; 30.9% had intradialytic hypertension (IDHT) while 19.8% had intradialytic hypotension (IDH). IDH was more prevalent among patients with diabetic kidney disease while IDHT was more common among patients with hypertensive nephropathy (P = 0.002). Female patients had higher mean BP parameters compared to male patients pre- and post-dialysis, but only changes in DBP were statistically significant (P = 0.029). Patients with CKD had higher mean BP parameters pre- and post-dialysis compared to patients with acute AKI and the differences were statistically significant.
Conclusion: Females had higher mean BP parameters than males. Patients with CKD had higher mean BP parameters compared with AKI patients. IDHT is a significant problem among patients on HD in our center. Measures to curtail this trend should be instituted with the goal of reducing morbidity and mortality.
Contexte:: La variation de la tension artérielle (PA) est fréquemment rencontrée pendant la procédure d’hémodialyse (HD). L’hypotension intradiale Et l’hypertension ont des implications pour l’issue du traitement et la morbidité et la mortalité globales des patients.
Méthodologie:: Une rétrospective Une étude a été réalisée dans l’unité de dialyse d’un établissement de santé tertiaire de la ville de Bénin chez les patients atteints de lésions rénales aiguës (LRA) Ou une maladie rénale chronique (ERC) sur une période de 3 ans. Les données recueillies comprenaient l’âge, le sexe, le type de maladie rénale, la cause d’une maladie rénale, La PA systolique au début de la dialyse et à la fin de la dialyse et la BP diastolique au début et à la fin de la dialyse.
Résultats:: Les données complètes ont été Disponible pour 217 patients. Cent sept patients (49,3%) n’avaient pas de changement significatif de la PA; 30,9% avaient l’hypertension intradialytic (IDHT) Tandis que 19,8% avaient une hypotension intradialytique (IDH). L’IDH était plus fréquente parmi les patients souffrant de maladie rénale diabétique tandis que l’IDHT était plus Commun chez les patients atteints de néphropathie hypertensive (P = 0,002). Chez les femmes, les paramètres moyens de PA étaient plus élevés que chez les hommes Avant et après la dialyse, mais seules les modifications de la PAD étaient statistiquement significatives (P = 0,029). Les patients présentant une IRC présentaient des paramètres moyens de PA plus élevés Avant et après la dialyse par rapport aux patients atteints d’IRA aiguë et les différences étaient statistiquement significatives.
Conclusion:: Les femmes avaient une Des paramètres moyens de BP que des mâles. Les patients atteints d’IRC présentaient des paramètres moyens de PA plus élevés que les patients atteints d’IRC. L’IDHT est un problème significatif Chez les patients en HD dans notre centre. Des mesures visant à réduire cette tendance devraient être mises en place dans le but de réduire la morbidité et la mortalité.
