Abstract
This study has been carried on 15 normal control and 15
patients with end stage renal failure under maintenance
hemodialysis treatment.
The age of these patients ranged between 23 - 38 years
with a mean of 29.733 + 5.012 years. Their duration of
dialysis treatment ranged between 6 - 25 months with a mean
of 14.6 + 6,28 months.
It was found that
1- Significant hypoxia (92.2 + 10.84) occurred in most
of the patients dialyzed with acetate dialysate. This
hypoxia was mainly transient with its greatest degree after
45 minutes.
2- Significant leucopenia occurred after 15 minutes of
starting dialysis (1960 + 656) and was corrected after the
first hour.
3- With acetate dialysate there was significant Co2
dialysance after one hour of starting dialysis (33.6 + 1.51)
4- ultrafiltration in the first two hours of the
session prevent the occurrence of hypoxia while significant
leucopenia occurred after 15 minutes of ultrafiltration and
was corrected after the first hour (Table 2).

5- Significant leucocytosis occurred at the end of
hemodialysis session.
6- Nasal oxygen administration in the first hour of
dialysis prevent the occurrence of hypoxia throughout the
dialysis session inspite of the occurrence of leucopenia and
Co2 dialysance.
7- Metabolic acidosis was significantly corrected after
45 minutes of dialysis till the end of the session while
ultrafiltration session could not correct it but significant
acidosis occurred at the end of ultrafiltration session.
8- significant increase of sodium level occurred during
and after the hemodialysis session while nonsignificant
changes occurred in ultrafiltration session (Table 9).
9- Significant hypokalemia occurred during and after
hemodialysis session (Table 8) while non significant
hypokalemia during ultrafiltration session (Table 9).
10- Significant increase of serum calcium level
occurred dur ing and after hemodialysis sess ion (Table e,)
while nonsignificant decrease occurred during
ultrafiltration session (Table 9).
11- The heart rate is regular and nonsignificantly
increased in all the sessions and the sudden increase in QRS
amplitude after hemodialysis might lead to diagnosis of left
ventricular hypertrophy.

Recommendation :
---------------
1 _ Hypoxia on dialysis should be well investigated and
properly treated particularly in patients with chest and
heart diseases and so Nasal oxygen administration in the
first hour of dialysis is recommended to prevent the
occurrence of hypoxia till the end of the dialysis
session.
2 _ Also patient with repeated hypoxia during dialysis can
be avoided it by using ultrafiltration in first 2 hours
of the dialysis session.
