Combined Fetal Pulmonary Artery Doppler and Proximal Humeral Ossification center for prediction of Neonatal Respiratory Distress Syndrome at term: a Cohort Prospective Study

Background: Fetal lung maturity is one of the huge dilemmas since a long time ago. Timing delivery crucial for safe fetal verification pulmonary diminishes respiratory morbidity possibility. Recently Pulmonary artery indices have been used to predict possibility RDS especially in early term. Together with humeral ossification center which has remarkable value estimation term gestation, both them can help prediction maturity. Aim Work: utilizing PHE Doppler accurate distress syndrome. The use gestation. Patients and Methods: Our study included 115 uncomplicated singleton pregnant women gestational age between 37 40 weeks patients from Al-Azhar University Ob/Gyn hospitals during period November 2019 October 2020. ultrasound scans were done inside 24 hours interval before Cesarean section. After delivery, neonatal APGAR score at 1, 5 minutes, diagnosis RDS, any NICU admission recorded respectively. Results: RI had statistically significant diagnostic performance predicting distress. ≤1.95 highest characteristics Among Artery Doppler, ≥0.79 characteristics. Conclusion: R.I could combination (sum) predicted better than using alone. Presence confirms
