- Abstract: Objective To explore the diagnostic value of color Doppler ultrasound for fetal intrauterine distress(FIUD)in high-risk puerperae in plateau areas.Methods A total of 130 puerperae in plateau areas and 130 puerperae in plain areas were enrolled.According to presence or absence of FIUD in different areas,they were divided into the plateau distress group(47 cases),the plateau normal group(83 cases),the plain distress group(31 cases)and the plain normal group(99 cases).All cases underwent blood flow detection of middle cerebral artery(MCA)and umbilical artery(UA)before delivery,and cerebral-placental ratio(CPR)was calculated.The incidence of FIUD was compared between high-risk puerperae in plateau area and in plain area.Gestational age,birth weight,cesarean section rate and blood spectrum parameters of MCA and UA were compared between the four groups.The predictive value of color Doppler ultrasound parameters for FIUD was analyzed by receiver operating characteristic(ROC)curves.Results The incidence rates of FIUD and severe FIUD were higher in patients of plateau areas than those in plain areas(36.15%,13.85%vs.23.85%,4.62%,P＜0.05).Compared with the plateau distress group,gestational age and birth weight were increased in the plateau normal group and the plain distress group(P＜0.05).Compared with the plateau distress group,PI,RI,S/D and CPR of MCA were increased,while PI,RI and S/D of UA were decreased in the plateau normal group and the plain distress group(P＜0.05).Results of ROC curve analysis showed that overall performance advantage of S/D of UA was the most obvious in the diagnosis of FIUD in high-risk puerperae in plateau areas.The diagnostic sensitivity of RI of MCA was the highest,and the diagnostic specificity of CPR was the highest(P＜0.05).Conclusion Color Doppler ultrasound has good diagnostic value for FIUD in high-risk puerperae in plateau areas,which can be applied as an effective clinical screening means for FIUD.
