Doppler investigations of placental and maternal flow have picked up a wide prominence as it could give significant data with respect to fetal prosperity and could be utilized to distinguish embryos in danger of bleakness and mortality, in this manner giving a chance to improve fetal results. In such manner, the accessible typical reference estimations of proportion () for example uterine corridor Doppler waveform parameters to those of umbilical course and impact of hypertension on Doppler waveform of the obstetric populace of various countries, were not unequivocally illustrated. The examination incorporates 60 pregnant ladies (in two periods 33-36 weeks and 37-40 weeks of incubation, 40 of them with pregnancy instigated hypertension and 20 as a control. The uterine courses and umbilical corridor files were determined just as proportions () for the RI and S/D, subsequent to gating the normal estimations of both uterine conduits files, the proportion between the uterine supply route and umbilical vein records was taken(normal uterine supply route/umbilical vein proportion, ). The mean ± SD of parameters expressed in the following manner:For PIH group At 33-36 weeks: RI =0.89 ± 0.26, PI = 0.94 ± 0.41and S/D =0.86 ± 0.31. The 95% confidence interval of the mean for four weeks were 0.77-1.0, 0.78-1.11, 0.74-0.99, respectively. At 37-40 weeks: RI= 1.00 ± 0.26, PI =1.05 ± 0.43 and S/D =1.03 ± 0.36. The 95% confidence interval of the mean for four weeks were 0..61, 0..31 and 0.81-1.25 respectively. For control group:At 33-36 weeks : RI =0.69 ± 0.08,PI= 0.73 ±0.13, and S/D=0.67 ± 0.09. The 95% confidence interval of the mean for four weeks were 0..80, 0..90 and0..78 respectively. At 37-40 weeks : RI= 0.99 ± 0.31, PI=0.95 ± 0.33, and S/D=0.92 ± 0.25. The 95% confidence interval of the mean for four weeks were 0..80, 0.76-1.13 and0.78-1.06respectively. A starter foundation of proportion ( of RI, PI and S/D) of Iraqi obstetric populace in and PIH at third trimester is most likely settled. The present investigation gave reference ranges in regards to uterine and umbilical supply routes , and S/ at 33-36 and 37-40 weeks of incubation in both.

The pregnancy induced hypertension increase the fetal mortality and morbidity and the using of Doppler umbilical artery indices decrease the fetal mortality and morbidity however, there is few complete data about the most frequently altered Doppler US parameters to predict fetal outcome in pregnancy induced hypertension . Methods This ia cohort prospective study done in two hundred and six women of second and third trimester presenting to antenatal clinic in Soba University Hospital at the department of Obstetrics & Gynecology, in the fetus unit and critical pregnancy in the period From June 2008 to April 2013 to assess the Doppler indices of umbilical artery in pregnancy induced hypertension for prediction of prenatal outcome; 105 pregnancy induced hypertension patients and 101 women with uneventful pregnancies as normal control group included in this study . Baseline investigations and color Doppler of umbilical artery were done. Statistical analysis of data were done using SPSS, Receiver Operating Characteristic (ROC) curve analysis was performed and the area under the curve (AUC) used to determine sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of umbilical artery Doppler indices to predict fetal outcome.Results The study determine that there was significant difference in Doppler indices in PIH and control group ( p<0.01, the mean indices of umbilical artery is higher in PIH group compared with normal pregnancy group , the mean different of S/D ratio was 0.40, mean difference of RI was 0.06 and the mean different of PI index was 0.16, high percentage of adverse fetal outcome had been reported in in Pregnancy Induced Hypertension group than in control , which was more in absent and reversed flow velocity in umbilical artery in Pregnancy Induced Hypertension compared with group of Pregnancy Induced Hypertension with present end diastolic flow velocity. Systolic/Diastolic ratio was most accurate in predicting adverse outcome in pregnancy induced hypertension patients, followed by the Pulastility index then the Resistance index (75%, 66% and 57% respectively).ConclusionThis study concluded that pregnancy induced hypertension leads to worsen placental insufficiently, which appears on the higher Doppler indices of umbilical artery to PIH patients when compared with normal pregnancy. A low diastolic flow and higher indices characterized the pregnancies with abnormal outcomes. Doppler of the umbilical artery was useful to predict fetal well being in PIH patients, high percentage of adverse fetal outcome had been reported in absent and reversed end diastolic flow velocity in umbilical artery compared with group of present flow velocity.

A prospective study investigated platelet cytosolic calcium in non-pregnant volunteers (n = 30) and samples from the umbilical veins of babies from both normotensive (n = 18) and hypertensive (n = 15) primigravidae, and their mothers. There was no significant difference between the neonatal umbilical venous platelet cytosolic calcium concentration (p[Ca2+]i) in babies born to normotensive primigravidae or to those whose pregnancies were complicated by gestational hypertension (88 x 9 (SE) 2 x 5) in normotensive primagravidae, 80 x 6 (2 x 8) in pregnancy induced hypertension without proteinuria, and 89 x 3 (3 x 2) nmol/l in pre-eclampsia. There was also no significant difference in the p[Ca2+]i from the umbilical veins of the pregnancies studied and those of non-pregnant female volunteers in the follicular phase of their menstrual cycle. This was despite a gradual and significant rise in p[Ca2+]i with increasing severity of disease in the mothers of the babies studied (119 x 9 (4 x 1) in normotensive primagravidae, 130 x 8 (7 x 3) in pregnancy induced hypertension without proteinuria, and 148 x 2 (4 x 5 ) nmol/l in pre-eclampsia). The mean maternal p[Ca2+]i in the three samples returned to concentrations comparable with those in non-pregnant subjects by 12 weeks after birth. These data demonstrate no significant difference between the mean p[Ca2+]i in non-pregnant women and those obtained from the umbilical venous blood of normotensive or hypertensive primigravidae. They suggest that the functional hypoactivity of neonatal platelets is probably not secondary to a decrease in basal p[Ca2+]i. They also suggest that the progressively raised p[Ca2+]i in normal and hypertensive pregnancies might be due to a pregnancy specific factor that does not cross the placenta,
