use of doppler flow velocity wave form of uterine and umbilical arteries as a method of fetal surveillance during progress of labor

ABSTRACT

Doppler velocimetry is a noninvasive, inexpensive technique which has a place in obstetric practice through early detection of fetal compromise and reduction of fetal morbidity and mortality via proper intervention. 43 full term pregnant women early in labor 10 primigravid and 33 multigravid [Parity < 3] vertux presention, which no major risk factor or previous uterine scar and normal CT or at the beginning of labour. Mean age 24.93 Y, SD 4.03 years. Measurements of uterine and umbilical arteries wave from through labour in relation to cervical dilatation were done and RI, PI, S/D were calculated. Shows changes in the mean uterine and umbilical arteries flow velocity waveform indices [RI, PI and S/D ratio] during peak uterine contraction which shows a progressive increase in all indices as the cervical dilation progressed. The results were statistically significant as P value were 0.000 for all three indices. Assessment of uterine and umbilical arteries Doppler should be an integral part of routine examination of high risk patient during labor
