[Arteriovenous fistula for pediatric hemodialysis. Experience of 9 years].

Seventy-eight A-V fistulas were constructed in 45 children whoses age were between 4 to 16 years, in order to use it for chronic hemodialysis. Twenty-four of them were external A-V shunts which were occluded by thrombosis in 13 instances and deinserted in 3 patients.

[Nutritional evaluation and use of a nutritional complement in children undergoing periodical hemodialysis].

Six uremic dhildren in periodic hemodialysis with protein-calorie malnutrition were studied. Three of them were given diet supplementation with a compound constituted by carbohydrates and essential amino acids. Evaluation at ,3 and 6 months with somatometry, rutine laboratory analysis, intravenous glucose tolerance test and plasma amino acid determinations, showed that patients with diet supplementation had a slight increase in height and body weight, improved glucose in tolerance, that was initialy detected, and an abnormal pattern of plasma amino acids not modified during the study.

[Hemodialysis with low sodium concentration in hypertensive uremic children].

In three hypertensive uremic children in whom hypertension was not controlled by sodium-free diet, ultrafiltration and hypotensive drugs, a total of twenty low sodium concentration hemodialyses were carried out. In all patients there was insignificant sodium excretion in urine and diastolic blood pressure diminished 10 to 20 mm Hg; two patients showed also reduction of systolic blood pressure. No important changes were seen in the serum concentrations of sodium, calcium and glucose.
