In vivo 1H NMR spectroscopy was used to investigate changes in the neurochemical profile of the hippocampus of 14-day old anemic mice (Hct = 20 2%). Anemia was induced by periodic blood draws during postnatal period P3 P14. Small, but significant changes were observed in myo-inositol, lactate and phosphoethanolamine levels, which indicate myelination changes in the developing brain resulted from iron deficiency. These results suggest that uncompensated phlebotomy-induced blood loss is a risk factor, especially for preterm infants, and has implications on blood transfusion practices.
