Abstract
The disturbances associated with chronic renal failure
almost always involves the body systems but the respiratory
disorders are frequent. The pUlmonaryfunction tests help in
diagnosis of these disorders.
The aim of this work is to ~tudy the ventilatory
abnormalities in patients with chronic renal failure before
and after haemodialysis. Twenty patients were studied and
selected with absence of overt lung and heart diseases, to
all of them full medical history and full clinical
examination was done. The following investigations were done:
complete urine analysis, full blood picture, blood urea and
serum creatinine, serum sodium and potassium, plain X-ray to
the chest and heart, abdominal ultrasonography and resting
EIOC.G.
ventilatory functions studies measuring slow vital
capacity (SVC), forced vital capacity (FVC), forced
expiratory volume of one second (FEV1), forced expiratory
volume of one second/forced vital capacity percent
(FEV1/FVC%),forced expiratory flow at 25%-75%and forced
expiratory flow at 0.2-1. 2 Ii ters before and after
haemodialysis by using vitalograph, peak expiratory flow rate
(PEFR)before haemodialysis, half an hour from the starting
of haemodialysis and after haemodialysis (four hours) by
using Peak Flowmeter.

The ventilatory function tests measured were compared
with the predicted values and with the base line ”before
haemodialysis”.
The results of this work showed that :
* All ventilatory functions before haemodialysis were below
normal values as compared with predicted values.
* A restrictive pattern was observed in the majority of
patients (75%) and obstructive pattern in the rest (25%)
before haemodialysis.
* There was improvement in all ventilatory functions studied
after haemodialysis where SVC and FVC showed statistically
non-significant improvement (P < 0.05) while FEV1,
FEVl/FVC%, FEF25%_75%’ FEFO•2-1•2 and PEFR showed statistically
significant improvement (P < 0.05).
* There was statistically non-significant correlation between
blood urea level and ventilatory functions (P > 0.05), also
there was statistically non significant correlation between
body weight and ventilatory functions (P < 0.05) but serum
creatinine level showed statistically significant negative
correlation after haemodialysis with PEFR (P < 0.05).
* The ventilatory functions in patients who lost 2 kgm or
more from body weight was greater than who lost less than
2 kgm.
* The percent of improvement of the ventilatory functions in
patients who received dialysis one year was higher than
those who received dialysis more than one year.
