Abstract

Objective: The present study inquired the effects of stopping ultrafiltration on arterial pressure in hemodialysis patients.
Methods: Our study was performed in 92 hemodialysis patients. Ultrafiltration was stopped after the 3rd hour of hemodialysis. Arterial pressure was measured in the supine position at 0, 5, and 10 minutes after ultrafiltration was stopped.
Results: Systolic arterial pressure increased by a mean of 4 mm Hg and diastolic arterial pressure increased by a mean of 2 mmHg at 10 minutes after ultrafiltration was stopped. With regard to the difference between mean arterial pressure measured before dialysis and just after stopping ultrafiltration (0. minute), systolic arterial pressure increased by a means of 5 mmHg and diastolic arterial pressure increased by a mean of 2 mmHg at 10 minutes after ultrafiltration was stopped in the patients with a mean arterial pressure decrease of ≥ 10 mmHg. However, stopping ultrafiltration caused no significant changes in the systolic arterial pressure or diastolic arterial pressure of the patients with a mean arterial pressure decrease of < 10 mmHg. An important correlation was determined between systolic arterial pressure elevation after stopping ultrafiltration and age, ultrafiltration rate, duration of hemodialysis, gender in the patients with a mean arterial pressure decrease of ≥ 10 mmHg. Age and gender were the independent variables, which affected the systolic arterial pressure elevation after stopping ultrafiltration.
Conclusion: In patients with a mean arterial pressure decrease of ≥ 10 mmHg, stopping ultrafiltration increases arterial pressure but this is a limited elevation. Stopping ultrafiltration related systolic arterial pressure elevation is more evident in females and in the elderly.
