Retardo de Crecimiento Intrauterino (Rciu) y Sus Alteraciones Bioquímicas.

The study of the retard of intra-uterine (RCIU) growth continues being important so much at obstetric level as pediatric. The interest is centered in the factors that impact directly in the flaws of growth in uterus and on its postnatal consequences. Besides the genetic potential, inherited of the parents, the development and survival of the fetus depends directly on the supply of the necessary substrates, as sugars, fatty acid, proteins, amino acids; this way it reaches its potential weight. If the readiness of these sources diminishes in persistent form, the survival of the fetus can it turns threatened. In this article a revision is made on the paper that have this sources and its alterations and implications in the cases of RCIU.
