Abstract
Optical density (OD) moderate rise to 450 mu in amniotic fluid(AF)for Rh-sensitized mothers is placed in lowest Liley zones. Lack of fetal death and the so-called unaffected fetus for newborn (NB) in this zone are of good prognosis. The relationship between OD rise in AF and severity of anemia was studied in 20 NB together with the need for exchange transfusion. Significant correlation between OD rise and cord blood hemoglobin (Hb) (rs = -0.77, p <0.005) was found. Significant dependence between cases in Liley zones 1 and 2 with Hb an indirect bilirubin cord blood was found (U= 1.5, p<0.001 y U= 6.5, p< 0.002 respectively). There was no significant relationship between values in Liley zones 1 and 2 and the need for exchange transfusion (p = 0.075, Fisher). Although there is significant relationship between OD values in Liley zones 1 and 2, and Hb and bilirubin cord blood values, it is important to point out the need for exchange transfusion in newborn placed in Liley low or unaffected zone.
