Study of pulmonary function test in chronic renal failure and the effect of hemodialysis

Abstract

Aim & objective: In this present study pulmonary function tests of chronic renal failure patients were compared with the normal healthy adults by the computerized spirometric values. Results: The lung function parameters in chronic renal failure are significantly reduced than the normal subjects. The lung function parameters were also measured in chronic renal failure who were undergoing regular hemodialysis A small but significant improvement in FVC, FEV1, FEV1%, PEF and FEF25- 75% was noticed consistently in most of the patients after hemodialysis. Though the improvement is more marked during 1 week of hemodialysis therapy, the values steadily and slowly improved after 3 months of hemodialysis therapy but was significantly lower than the normal values. None of our patients attained even near normal values at the end of 3 months of hemodialysis. Blood parameters like blood urea and serum creatinine levels were significantly reduced in repeated hemodialysis. Conclusion: This study reconfirms the already established fact of restrictive type of ventilatory defect in chronic renal failure patients this study has reflected the effects of hemodialysis on pulmonary function test in chronic renal failure patients over a short duration.
