ABSTRACT

Dialysis filter can cause activation of complement and release of anaphylatoxines which can have a deteriorating effect on respiratory system. Aim of the work: To compare the effect of bicarbonate versus acetate haemodialysis on the pulmonary function test and blood gas parameters. Material and methods: cross sectional study of fifty chronic renal failure patients on regular haemodialysis without history of chronic pulmonary disease were randomly selected for dialysis either by bicarbonate or acetate dialysate twenty five each with same machine and duration of dialysis. Evaluation thorough medical history and determination of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, and
