The Significance Of Umbilical Artery PH Value And Apgar Score In The Diagnosis Of Neonatal Asphyxia

Objective: This article explores the coincidence rate between the diagnosis of prenatal fetal distress and the diagnosis of postpartum neonatal asphyxia,in order to understand whether there is excessive intervention in clinical obstetrics;explore the umbilical artery blood PH value,Apgar score and multiple organs caused by neonatal asphyxia and hypoxia In order to understand the diagnostic value of the aforementioned two criteria for multi-organ damage in neonatal asphyxia;to explore the correlation between the PH value of umbilical artery blood and Apgar score.Methods: In this paper,a total of 80 patients who gave birth in the Affiliated Hospital of Inner Mongolia Medical University from December 2018 to August 2019 were selected based on the method of prospective research and according to the inclusion and exclusion criteria of this topic.The prenatal diagnosis of fetal distress was the research object.Immediately after the fetus was delivered,the umbilical artery blood gas analysis and the 1-minute Apgar score were performed,and the neonatal outcome was tracked.Compare the diagnosis with umbilical artery blood PH value alone,Apgar score alone for diagnosis,combined diagnosis with umbilical artery blood PH value and Apgar score.Under the three diagnostic criteria,the coincidence rate of the diagnosis of prenatal fetal distress and the diagnosis of postpartum neonatal asphyxia,To explore the correlation between the PH value of umbilical artery blood,Apgar score and multiple organ damage in neonatal asphyxia,and discuss the correlation between the PH value of umbilical artery blood and Apgar score.Results: 1.Under the three diagnostic methods,the diagnosis of prenatal fetal distress is not completely consistent with the diagnosis of postpartum neonatal asphyxia,and there are significant differences(P<0.05),that is,there is excessive intervention in clinical obstetrics;2.There is a significant difference between the PH value of different umbilical artery blood and multiple organ damage in neonatal asphyxia(P<0.05);3.There are significant differences between different Apgar scores and multiple organ damage in neonatal asphyxia(P<0.05);4.The specificity and false negative rate of the umbilical artery blood PH value diagnosis group and the combined diagnosis group of umbilical artery blood PH value and Apgar score were higher than those of the Apgar score diagnosis group alone,and the sensitivity and false positive rate were lower than those of Apgar score alone.Diagnostic group;5.There is a positive correlation between the PH value of umbilical artery blood and Apgar score(R=0.365).Conclusion: 1.The diagnosis rate of postpartum neonatal asphyxia is lower than that of prenatal fetal distress,and there is a phenomenon of clinical over-intervention.Over-intervention has an impact on the rate of cesarean section and the incidence of preterm delivery.Clinicians should strictly control the diagnostic criteria of fetal distress and the indications of cesarean section for termination of pregnancy due to fetal distress,so as to indirectly reduce the rate of cesarean section and reduce the occurrence of premature delivery.2.Umbilical artery blood PH value and Apgar score have diagnostic significance for multiple organ damage caused by neonatal asphyxia and hypoxia.3.The sensitivity and specificity of umbilical arterial blood PH value and Apgar score can complement each other,and should be combined in clinical application.4.There is a positive correlation between the PH value of umbilical artery blood and Apgar score.
