Fetal lung volume and pulmonary artery resistance index for prediction of neonatal respiratory distress syndrome

Background: As gestational age grows, the risk of newborn respiratory distress syndrome (RDS) diminishes because lungs are last foetal organs to properly mature. While neonatal RDS does not just occur following preterm births, it is often thought as a disorder premature babies. This study sought determine how prenatal lung capacity and Pulmonary artery resistance index (PARI) affected probability that would occur. Methods: prospective observational was carried out on 200 pregnant women aged 20-35 years, with between 36-40 weeks singleton pregnancy. According outcome patients were classified into two groups: group A: 26 cases noenatal B: 174 without RDS. All subjected 2D ultrasonography 3D ultrasonography. Results: Fetal volume (FLV) significant predictor (AUC: 0.820, p <0.001), at cut off value ≤35, 88.5% sensitivity 68.4% specificity. PARI 1 5 min Apgar score significantly lower in neonates who developed those didn’t (p<0.001). Conclusions: FLV estimated fetal weight measurement using may be reliable non-invasive indicator incidence pregnancies when progression present. for cutoff ≤35 cm3 specificity 68.4%.
