Effects Of Different Delivery Modes On Umbilical Artery Blood Gas Analysis Of Infants

Object:To study the changes of umbilical artery blood gas analysis in neonatal Apgar score?8 points during cesarean delivery and vaginal delivery,and to guide the selection of delivery mode of children with clinical criticality.Methods:94 pregnant women with no pregnancy complication and full-term delivery were divided into cesarean section group and vaginal delivery group according to different delivery methods.Umbilical artery blood gas analysis results were analyzed and compared.Results:Cesarean section group: The pH value of umbilical artery was 7.23±0.12,PaO₂?21.15 ± 14.96?mm Hg,PaCO₂?52.06±9.47?mm Hg and lactic acid?3.37±1.34?mmol / L.Vaginal delivery group: The pH value of umbilical artery was?7.19±0.10?,PaO₂?24.34±13.10?mm Hg,PaCO₂?56.55±9.91?mm Hg and lactic acid?4.97±2.26 mmol/L?.There were significant differences in pH,PaCO₂ and lactate levels between the two groups?P<0.05?.While PaO₂ is not statistically significant.There are 2 cases?4.88%?of neonatal umbilical cordblood gas analysis pH value <7.15 in cesarean section group,13 cases?24.53%?in vaginal delivery group whom neonatal umbilical cord blood gas analysis pH value <7.15.The differences between the two groups were statistically significant?P<0.05?.Conclusion:Umbilical artery blood gas analysis and lactic acid determination can objectively reflect the abnormal situation of neonates and the internal environment of the body.Cesarean section delivery can reduce the risk of neonatal acidosis.Umbilical artery blood gas analysis and lactic acid determination have important clinical significance for the selection of delivery methods for clinical high-risk children.
