Abstract

Pre-eclampsia (PE) is considered one of the major causes of maternal death in pregnant women in both developed and developing countries. To identify umbilical artery doppler indices and their prognostic capabilities in pre-eclamptic mothers using doppler Ultrasound (U\S).A prospective study containing 79 high-risk pregnant women in a governmental hospital in Jazan, Saudi Arabia. Blood pressure and doppler U\S parameters from the umbilical arteries of the mothers and the fetus were measured for them using a general electric (GE) U\S machine with a 3.5 MHz curvilinear transducer. Study sample demographic variables included (maternal age, fetal weight, and amount of amniotic fluid), also doppler U\S indices (Resistivity Index (RI), Pulsatility Index (RI), and the systolic-diastolic ratio (S/D) were recorded.  In the current study it was revealed that (67.1%) of them had a normal pregnancy, while (32.9%) were had preeclampsia, the mean value for the PI equal to 0.98 and 1.30 also for the S/D ratio the mean values are equal to 2.37 and 3.5 for normal and preeclampsia respectively. According to this study's findings, the value of doppler US to exclude preeclampsia is high. doppler velocimetry investigations of the umbilical artery can provide obstetricians with information about fetal welfare, allowing them to enhance fetal outcomes. Umbilical artery PI is the best predictor of PE. Implications for practice: The study will be shared with the obstetricians to improve their skills on the feasibility of using doppler parameters to predict bad pregnancy outcomes‎.
