Effects of Early Short-term Intravenous Iron Supplements Combined EPO in Preterm Infants

Effects of Early Parenteral Iron Combined Erythropoietin in Preterm Infants

There are wide variations in iron supplementation practices in NICU.Guidelines on pediatric Parenteral nutrition suggested the dose of 200μg/kg.d iron by parenteral nutrition.

The study was approved by the ethics committee of Xinhua Hospital, and all parents gave written informed consent.

Study Design This was a randomized, controlled, double-blind, interventional trial of iron (iron sucrose) supplementation given from age of 1 day until full 2 weeks to preterm infants in NICU, who divided into three groups, control(PN without iron and EPO), Vifor and vifor and EPOE group, according to the recommended dosage of ESPEN .

Outcome Measures General information and indicators including anemia iron storage were measured. And the same time oxidative stress indicators were monitored at age of 1day and 2 weeks.

General growth parameters including the blood sugar, liver and renal function index before and after the intervention were tested.

Hematological evaluation including RBC, Hb, MCV, MCH, MCHC, RET, CRP were mesured before and after the intervention. The three groups were all peripheral blood.

Iron storage evaluation including ferritin, serum iron, TIBC on the days were measured before and after the intervention. We used the radio-immunoassay method to test the ferritin (DADE BEHRING, Germany), the chemical method to the serum iron and the automatic biochemical analyzer (automatic biochemical analyzer, 7600, HITACH).
