Abstract
Objective To explore the relationship hetween umbilical cord artery blood gas analysis and Apgar score and to evaluate the clinical significance of their combination. Methods Results of umbilical cord artery blood gas analysis and Apgar scores were obtained immediately after delivery in 184 normal term infants with the outcomes of these neonates followed-up. Results The average value of pH in the distress group was ( 7.25 ± 0.21 ) and was ( 7.29±0.04 ) in the non - distress group. Percentage of neonates with umbilical artery pH ＜ 7.2, ＜7.1 , ＜ 7.0 were 30.36％, 23.21％, 16.07％ in the distress group and were 14.06％, 10.16％, 5.47％ in the non - distress group ( P＜0.05 ) . Among the neonates with Apgar scores≤7, percentage of individuals with pH value below boundary ( 7.2, 7.1 or 7.0 ) was higher than in those with Apgar scores ＞ 7 (P＜0.05 ). Among the neonates with Apgar score≤7, sensitivity and specificity were 58.82％ and 57.14％ when pH ＜7.2,55.88％ and 73.08％ when pH ＜ 7.1, and were 35.29％ and 75.00％ when pH ＜ 7.0. With the decrease of umhilical blood pH, incidence rate of hypoxic ischemic encephalopathy and pathologic jaundice increased. Conclusion Combination of Apgar score and umbilical cord gas analysis reflects the hypoxic and ischemic status of the fetus more objectively and sensitively and might be able to play an important role in predicting the immediate and long - term prognosis of the neonate.关键词
