Introduction: Blood pressure variability (BPV) is a frequent complication during hemodialysis. Our aim was to determine the amplitude and the factors associated with intradialytic blood pressure variability amongst patients with kidney failure on chronic hemodialysis in Cameroon.
Methods: a cross-sectional analytic study was conducted at the Douala General Hospital, including consenting patients aged over 18 years on hemodialysis for more than 3 months. We excluded those with an acute complication before dialysis which could modify the blood pressure. Data collected were socio-demographic and clinical. Each patient was followed on one hemodialysis session during which five blood pressure measurements were taken hourly. We assessed the intra-dialytic BPV using Blood Pressure average real variability (ARV). Values above the median were considered abnormal variations. Statistical analysis was performed using SPSS 25.0 software with significance defined as p-value < 0.05.
Results: one hundred and sixty-nine (169) patients were included with 69.23% being male. The mean age was 47.68 (13.76) years. The main comorbidities were hypertension (94.67%) and diabetes (15.98%). The median (min-max) hourly change in systolic BP was 11.50 (8.00-16.50) mmHg. Patients with abnormal amplitude of variation accounted for 49.7% and the independently associated factors were: age ≥ 70 years, high blood pressure, the use of antihypertensive medication, dialysis vintage ≥ 5 years, and ultrafiltration rate ≥ 850 ml/h.
Conclusion: the amplitude of variation in intradialytic systolic BP was high with a significant prevalence of abnormal variation; associated factors related mainly to the patient's comorbidities and lifestyle.
