Objective: To determine the relationship between the degree of fetal affectation and maternal anemia by Doppler velocimetry middle cerebral artery in anemic mothers. Methods: Prospective, observational and analytical study, of 35 patients between 26 and 28 weeks of gestation, including 15 diagnosed with anemia (hemoglobin less than 11 g% and hematocrit <33%) constituted the study group and 20 the control group. After informed consent cerebro-placental index was established. We excluded patients who had severe pathologies leading to chronic hypoxia. Setting: Unidad de perinatologia del Hospital Universitario de Caracas. Results: The mean age was 28 years for the study group and 27.39 years for the control group, the gestational age of 27.02 weeks for both groups. The predominant family history was diabetes in both groups, followed by hypertension. The average hemoglobin and hematocrit was 10.21 g% and 31.23% for the study group and 12.05 g% and 36.21% for the control group. The peak systolic velocity of the fetal middle cerebral artery was 34.47 cm / sec for the study group and 34.43 cm / sec for the control group, the average values of systole-diastole of middle cerebral artery, S / D: 4.84 and S / D: 5.62, umbilical artery S / D: 2.87 and S / D: 2.96 and cerebro-placental indices of 1.71 and 1.91, for study groups and control respectively, yielded no statistically significant differences. There was also no statistical difference when comparing the groups according to the number of pregnancies, fetal weight and sex. Conclusions: The maternal anemia study did not directly affect the fetal circulation. There fetal impairment, or elements of hypoxia in patients anemic mothers.
