The Value Of Doppler Indices In Prediction Of Fetal Lung Maturity In Benha University Hospitals

Background: Fetal lung maturity (FLM) determines whether a fetus may survive following birth. Despite developments in neonatal surveillance equipment, pulmonary hypoplasia still ranks as the top cause of newborn death and morbidity. This study aimed to The function of ultrasonic imaging in forecasting FLM and its impact on fetal outcome can be evaluated by establishing the typical characteristics of fetal lung development at various gestational ages and investigating their relationship with gestational age Methods: This prospective cohort study included 100 women coming at Benha University Hospitals & Benha Health Insurance Hospital. All patients were divided into 2 groups: Group I (N=35): Neonates with respiratory distress (RD). Group II (N=65): Neonates with non-respiratory distress (non-RD). Results: Sensitivity of acceleration time in RDS prediction was 83.6% versus 85.6% for ejection time, their specificity was 90.5% and 94.3% respectively, while AT\ET ration was higher in sensitivity and specificity (91.7% and 95.7% respectively) and 94% test accuracy. Conclusion: In newborns with high sensitivity and specificity, ejection-time (ET), acceleration-time, and acceleration-time/ejection-time ratio can help to predict FLM and respiratory distress syndrome. Neonates with RD may have low amniotic fluid index, resistance index, Bi-parietal diameter, femur length and abdominal circumference.
