Assessment of pulmonary functions in chronic renal failure patients with different haemodialysis regimene

ABSTRACT

In this study of pulmonary function tests in chronic renal failure patients and controls [on thrice/week hemodialysis and on daily dialysis], a restrictive ventilatory disturbance was found as evidenced by decreased forced vital capacity [FVC], decreased forced expiratory volume in first second [FEV1] with peaked expiratory flow rate [PEFR] and forced expiratory flow. There was a significant negative correlation between B. urea, S. creatinine with FEV1, FEF 25-75%, 50% and PEFR. The study showed the effect of daily dialysis, a new growing hemodialysis modality in many centers in the world, that was established to improve the patients' quality of life, many systems and the long-term costs of medications and complications' management. A significant reduction in the restrictive pattern of daily dialysis patients with no obstructive type of pulmonary function tests per se and an improvement in B. urea, but not S. creatinine, were detected
