The correlation between the Apgar scores of 162 neonatal 1 minute after birth and the result of maternal arterial and umbilical cord blood gas analysis was studied. The results were as follows: (1) With decreasing neonatal Apgar score, the value of the pH, PO2, HCO3, TCO2 and actual base excess (ABE) of the maternal arterial and umbilical cord blood also decreased markedly, while the PCO2, except that of the maternal arterial blood, increased obviously, and mixed acid base imbalance and hypoxemia also significantly increased (P less than 0.01). (2) Of the neonates with umbilical arterial blood pH less than or equal to 7.2, the proportion of neonates with Apgar score less than or equal to 3 amounted to 100%; that with on Apgar score of 4-7, was 77.7%; And that with on Apgar score of 8-10, was 56.31%. The difference was highly significant statistically (P less than 0.01).
