Relationship between prophylactic Erythropoietin on Anemia of prematurity in very low weights births and often transfusión, "Germán Urquidi" Maternoinfantil Hospital,  March 2009 to January 2010.

Very low weight preterm newborn have commonly anemia, requiring repeated blood transfusions, of which are many risks. Erythropoietin influences development and increases population of red blood cells. Determine if the use of Erythropoietin to prevent Anemia of prematurity reduces red-cell transfusions frequency. Internal retrospective cohort study. 24 low weight preterm newborn < 32 gestational weeks age. Excluding deaths, prior anemia, intraventricular hemorrhage, sepsis, delay of intrauterine growth, congestive heart failure, surgeries or major congenital malformations. Exposed group: Weight 1000 g., average of 2 transfusions and 54 days of placement; not exposed: 1250 g., 2.23 transfusions and 38 days hospitalized. The use of Erythropoietin can't reduces transfusions in Anemia 's very low weight preterm newborn treatment, neither prevent its production.

Palabras clave : Erythropoietin; preterm newborn; anemia; red-cell transfusions.
