Abstrakt: Aim of work: To determine the relationship between the gestational age and the (PSV, RI and PI) of the ductus arteriosus and lung maturity and to determine the effect of pregnancy-induced hypertension on these parameters. Material and methods: A prospective cohort study was carried out, in which 90 pregnant women at gestational age 34–40 weeks were selected, 50 as a control and 40 with pregnancy-induced hypertension (PIH). They underwent measurement of ductus arteriosus (DA) (PSV, RI and PI) and observing the percentage of the development of neonatal RDS in control and PIH cases. Results: There was a direct correlation between the PSV, PI, RI of ductus arteriosus and development of neonatal RDS. A cutoff value for GA, PSV, RI and PI for prediction of the subsequent development of RDS was determined in control ((35.7, 89.9, 0.80, 2.14), with sensitivity (71.4, 100, 85.7, 85.7%) and specificity (93, 97.7, 97.7, 93%), respectively), and PIH (35.7, 91.1, 0.80, 2.14), with sensitivity (71.4, 100, 85.7, 100%) and specificity (71.7, 100, 85.7, 100%), respectively). Conclusions: We concluded from our study that for the detection of fetal lung maturity in fetuses of GA from 34 to 40 weeks, it is better to combine GA, PSV, RI and PI of DA to detect lung maturity in control and PIH groups to get more accurate results.
