Abstract:
Objective To predict fetal distress in oligohydramnios fetuses in mid-pregnancy by monitoring the blood flows in middle cerebral artery,renal artery and umbilical artery by means of ultrasound.Methods Totally 104 mid-pregnancy women with oligohydramnios in some hospital from January 2020 to May 2022 were selected retrospectively,and were divided into a distress group(n=43)and a non-distress group(n=48)based on the presence of fetal distress.Logistic multivariate regression was used to analyze the risk factors for the occurrence of fetal distress;the predictive value for fetal distress was assessed with ROC curves;a Bayesian network model was constructed and validated.Results The independent risk factors for fetal distress included abnormal findings in fetal movement,fetal cardiac monitoring,lipid levels and blood rheology indices and abnormal parameters of middle cerebral artery,renal artery,and umbilical artery(P＜0.05).Higher predictive efficiency could be obtained for fetal distress when the blood flow parameters of middle cerebral artery,renal artery and umbilical artery were combined than only the parameters of only one artery were involved in.The Bayesian network model predicted an increase in the incidence of fetal distress from 49.9％to 61.50％when the probability of abnormality in all the three artery parameters was 100％,which proved to gain a high net benefit.Conclusion For mid-pregnancy women combined monitoring of the blood flow parameters of middle cerebral artery,renal artery and umbilical artery may predict fetal distress effectively.[Chinese Medical Equipment Journal,2024,45(5):60-66]
