Abstract

Background: Because of accurate dating of gestational age, ultrasound imaging is attractive tool in avoiding maternal & perinatal mortality, particularly when done in the first trimester. Ultrasound is used to monitor foetal growth. Aim of the work: To assess the accuracy of ultrasound markers in the prediction of lung maturation by measuring certain parameters and comparing the results with the neonatal outcome by using APGAR score at 1 minute & 5 minutes, neonatal respiratory distress syndrome, and NICU admission. Patients & Methods: This study is a cohart study on 120 pregnant women (37:39 wks. gestation) with the previous one to three (1: 3) caesarean sections at Al Hussein and Mansheyet Al Bakri Hospitals during the period from October 2021 to June 2022. Results: The Biparietal Diameter ≥92 mm was associated with foetal lung maturation & was found to have Sensitivity (63.6%)&good Specificity (80.6%). The amniotic fluid particles (Vernix) were found to have good Sensitivity (72.7%)&low Specificity (56.3. The placental maturation grade III were found to have good Sensitivity (72.7%)&low Specificity (59.2%). The colon echogenicity grade III was found to have good Sensitivity (72.7%)&lowest Specificity (52.4%). The kidney length was found to have low Sensitivity (63.6%)&good Specificity (76.7%). The lung/liver echogenicty was found to have Sensitivity (63.6%)&good Specificity (88.3%). Conclusion: because of accurate dating of gestational age, ultrasound imaging is attractive tool in avoiding maternal & perinatal mortality. Termenation of pregnancy after the age of 39 wks was the best time to exclude TTN and NRDS.
