Abstract:
Objective To observe the hemodynamic variations of both the mother and fetus when the pregnancy was complicated with early-onset of severe preeclampsia, and to evaluate the role of monitoring the blood flow with Doppler in the management and prognostic value in the same condition. Methods A prospective case-control study was conducted in 36 pregnant women admitted for early-onset of severe preeclampsia (S-PE). The control group included 72 healthy pregnant women matched with the S-PE group. All had color Doppler sonography monitored during this study period. Data were collected for the umbilical artery (UA) pulsatility index (PI) and systolic/diastolic ratio (S/D) , the middle cerebral artery (MCA) PI and S/D and the maternal mean uterine artery (UtA) PI and S/D. Those subjects with adverse perinatal outcomes were followed up after birth. Results The mean Doppler indices(S/D and PI) of fetal UA, MCA and maternal UtA were all declined gradually with the advancing gestational ages in both groups. The values of UA-S/D, UA-PI, UtA-S/D, and UtA-PI in the early-onset S-PE group were significantly higher than those of the control(P
