Abstract
We reported (Ped. Res. 1981:15:1452A) that the mothers whose AF LE showed reduced ST lowering property delivered babies who developed complications in the neonatal period. This study included babies of all weights. To exclude the impact of premies we examined the predictive value of ST lowering property of the AF LE for newborns weighing >2500gm. The ST was measured on 64 AF LE by the standard method. The ST sum was calculated by adding the volume and the ST (both are the minimum volume (ul) of the AF LE required to maximally lower the ST (dynes/cm)).
In 28 babies (♂15,♀13), the ST sum was≤40; 22 were normal and 6 (♂5,♀1) showed complications: meconium staining-3, ABO incompatibility-2, hyperbilirubinemia requiring phototherapy-2, and Down's syndrome-1. In 36 babies (♂17,♀19), the ST sum was >40; 19 were normal and 17 (♂6,♀11) showed complications: Rh and other isoimmune hemolytic diseases requiring exchange transfusion-4, hyperbilirubinemia requiring phototherapy-2, ABO incompatibility-2, polycythemia requiring partial exchange transfusion-1, hypoglycemia-4, possible sepsis-1, and meconium staining-3. The mothers of only 5 babies showed a prenatal condition suggesting a need for the baby's observation. Conclusion: ST sum value is a nonspecific indicator of a baby's health. A high value suggests a need for observation of a ⩾2500gm baby; a low value suggests an absence of complications subsequent to delivery.
