| Popis: | Background: PIH is associated with increased vascular resistance and decreased utero -placental perfusion resulting in an increased incidence of foetal hypoxia and impaired foetalgrowth.The objective of this study was to assess the diagnostic performance of S/D ratio, resistance index(RI), pulsatility index (PI) and cerebro-placental ratio (CPR) in the prediction of adverse perinatal outcome in PIH and IUGR. Objective: is to determine S/D ratio, RI, PI, CPR and asses their diagnostic values in the prediction of adverse perinatal outcome.Material& Methods:50 pregnant patients with PIH and IUGR, beyond 28 weeks of gestation, were prospectively studied at P k das institute of medical college,vaniyamkulamand subjected for Doppler study of the umbilical artery and foetal middle cerebral artery. The abnormality of above parameters was correlated with the major adverse perinatal outcome.Results:Patients with abnormal Doppler parameters had a poor perinatal outcome, compared to those who had normal Doppler study. The cerebro-placental ratios(CPR) had the sensitivity and specificity, positive and negative predictive values of 95%,76%,73%,95% respectively with Kappa value of o .68(good agreement) and p value of .000 which was statistically significant, for the prediction of major adverse perinatal outcome.Conclusions:This study shows that Doppler study of umbilical and foetal middle cerebral artery can reliably predict the neonatal morbidity and helpful in determining the optimal time of delivery in complicated pregnancies. The CPR is more accurate than the independent evaluation of S/D, RI, PI, in identifying foetus with adverse perinatal outcome. |
