Abstract
The present study comprised (40) pregnant women those attended Ain Shams University maternity hospital our study aimed to evaluate the value of umbilical artery and standard fetal assessment on neonatal outcome in (IUGR) cases.
We categorized the women into two groups:
Group A: (20) pregnant ladies having fetuses with (IUGR) with Abnormal umbilical artery blood flow (AUA).
Group B: (20) pregnant ladies having fetuses with (IUGR) with normal umbilical artery blood flow (NUA).
All ladies underwent full history taking (personal, past, family and obstetric history). Ultrasound to determine the expected gestational age and fetal weight, UA Doppler Velocimtery and Biophysical profile.
The mean RI among group A is (0.81 + 0.09) and among group B is (0.62+0.10). Group A had a higher mean RI compared to group B with statistically highly significant difference in between.
There is no significant between RI and parity, maternal age, apgar score after 1 minutes, fetal gender among total cases.
There is significant inverse correlation between RI and GA, Apgar score after 5 minutes among total cases.
There is inverse correlation between RI and fetal weight among group (A), there is highly significant inverse between RI and GA among group (A), there is highly significant inverse correlation between RI, FW among total cases, highly significant between both group as regard RI.
The best cut off value equal to 0.67
The sensitivity, specificity, positive predictive value and negative predictive value of RI as a predictor for fetal out come are (68 %, 99 %, 80 % and 55 %) respectively.
This indicates that RI is considered a good negative test than positive in other words when its level below 0.67 it expect good fetal outcome, but when its level above 0.67 we need a confirmation by another test.
So concluded RI is considered a good negative test than positive in other words when its level below 0.67 it expect good fetal outcome but when its level above 0.67 we need a confirmation by another test. A cut off value of RI 0.67 can be safely used with high degree of sensitivity and specificity.
