Abstract
Background: Fetal lung immaturity is a major problem in the management of elective birth with respect to predicting the development of infant respiratory distress syndrome (IRDS) in the neonate after birth.
Aim and objectives: The aim of the study was to evaluate the efficacy of thalamus echogenicity by ultrasound as a marker for fetal lung maturity.
Subjects and methods: This cross-sectional exploratory study was conducted in Obstetrics and Gynecology Department of Ain Shams University Maternity Hospital from January 2021 to October 2021. This study was conducted on 80 pregnant females. Patients were divided into 2 groups: group (1): 34th-35th weeks and group (2): 36th-37th weeks. Each group will include 40 pregnant women.
Results: There was statistically significant association between gestational age and thalamus echogenicity but there was no statistically significant association between gestational age and abnormal fetal presentation, preterm delivery, 1 and 5-minute APGAR score, fetal weight and gender, NICU admission, RDS and mortality.
Conclusion: Ultrasound assessment for fetal lung maturity is a useful non-invasive procedure with good predictive values and accuracy. Best success in predicting the fetal lung maturity, accompanied by placental calcification grade II and III and thalamic echogenicity. However, no single parameter alone could show a definitive sign.
