The application value of the umbilical artery blood gas index combined with the Apgar score in the assessment of neonatal asphyxia
Objective To investigate the application value of umbilical artery blood gas index combined with Apgar score in the assessment of neonatal asphyxia.Methods A total of 157 neonates with 1min Apgar score ≤7 admitted to our hospital from January 2021 to March 2023 were selected as the study group,and another 160 neonates with 1min Apgar score ≥8 during the same period were selected as the control group.The data of umbilical artery blood gas indexes[pH value,partial pressure of oxygen in arterial blood(PaO2),partial pressure of carbon dioxide in arterial blood(PaCO2),bicarbonate(HCO3-),buffuer excess(BE)and carbondioxide combining power(CO2CP)]and organ injury were collected in two groups of neonates.The predictive efficacy of Apgar score and umbilical artery blood gas indexes for neonatal organ injury was analysed.Results For Apgar score,pH value,PaO2,PaCO2,HCO3-,BE,the study group was significantly lower than the control group(t=2.446-8.403,respectively),the severe group was significantly lower than the mild group(t=2.937-8.114,respectively),the injury group was significantly lower than the non-injury group(t=3.213-9.225,respectively);for CO2CP,the study group was significantly higher than the control group(t=5.004),the severe group was significantly higher than the mild group(t=4.023),and the injury group was significantly higher than the non-injury group(t=4.907),all the differences were statistically significant(all P<0.05).Comparing the sensitivity,specificity and compliance of the three methods for predicting neonatal organ injury,the Apgar score was significantly lower than that of umbilical artery blood gas analysis(x2=1.728,4.146 and 4.747,respectively),the Apgar score was significantly lower than that of combined assessment(x2=5.722,9.013 and 10.581,respectively),and the umbilical artery blood gas analysis was significantly lower than that of combined assessment(x2=4.551,3.693,and 4.384,respectively),all the differences were statistically significant(all P<0.05).Conclusion Umbilical artery blood gas analysis combined with Apgar score can effectively improve the sensitivity,specificity and conformity of assessing organ damage in asphyxiated neonates,which is conducive to reducing the misdiagnosis rate of neonatal asphyxia,and is of great clinical value in assessing the prognosis of neonates.
