[Perinatal fetal distress: correlations between Apgar score at birth and assay of CK-BB in umbilical cord blood].

32 newborn infant's umbilical cord blood CK-BB activity was tested at birth. 14 of them had a superior to 7 Apgar score at first and fifth minutes, whereas 18 newborn infant Apgar score was inferior to 7. The CK-BB activity was significantly higher in newborn infants having a low Apgar score at birth. A low Apgar score at first and fifth minutes together with a high CK-BB activity must be considered a nervous trouble signal and a warning in order to look after children's psychomotor skills more strictly and individual neurological damage.
