Исследование Безопасности Неионных Рентгеноконтрастных Средств И Их Влияния На Функциональные И Метаболические Показатели У Детей С Нефропатиями

A study was conducted to assess the safety of non-ionic contrast media in paediatric nephrourology and their impact onto renal function and homeostasis, reflecting the risk of development of contrast-induced nephropathy. After contrast media use we observed elevation of cystatin C and endothelin, decrease of sodium fractional excretion and hypocoagulation were identified. The results obtained indicate that renal hypoperfusion with a consequent decrease of sodium fractional excretion and elevation of endothelin production may play a role in contrast-induced nephropathy. Increased serum cystatin C reflects adverse impact of contrast agents on renal function. Hypocoagulation effect requires that coagulation disorders must be excluded before use of contast media. Key words: children, contrast-induced nephropathy, renal function, cystatin C, endothelin, hemostasis. (Pediatric Pharmacology. – 2010; 7(2):78-82)
