The value of uterin artery, cerebral - umbilical ratio doppler ultrasound and non stress test in predition of fetal distress in patients with preeclampsia

Abstract

The cross-sectional descriptive study of 229 patients with preeclampsia in pathological obstetrics and gynocology from 04/2014 to 07/2015. Objective: the study value of spectrum image uterine artery Doppler, the middle cerebral artery to umbilical artery resistance index (C/U RI) ratio, non stress test and combination of these three indicators in prediction of fetal distress in patients with preeclampsia. Results: the C/U RI ratio with “ cut off ” value for predictive fetal distress is 1,1 with sensitivity, specsificity are 75% , 74% . When the uterine artery Doppler have notch, the diagnostic value on fetal distress with sensitivity, specsificity are 76% and 77%. Non tress test value for predictive fetal distress with sensitivity is 70% and specsificity is 90% . The diagonotic value when combination of C/U RI ratio, spectrum image uterine artery Doppler and non tress test for fetal distress with sensitivity, specsificity are increased 87% và 93% . Conclusion: The spectrum image uterine artery Doppler, the middle cerebral artery to umbilical artery resistance index ratio, non stress test are good predictor of fetal distress in patients with preeclampsia, espcecially when combine these three indicators.
