A study of fetal lung maturity correlated by various USG parameters at a primary health care centre
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 5, Issue 2
Abstract
Background: Fetal lung maturity is the key factor for the survival of prematurely delivered newborn baby. Ultrasonography is considered the gold standard to know the fetal lung maturity. Certain ultrasonographic parameters like placental grading, bi-parietal diameter, lower limb epiphyseal centers and free floating particles in amniotic fluid can be used as predictor of fetal lung maturity. Aim: To assess the fetal lung maturity with the help of USG parameters at primary health care centre. Material and Methods: Seventy-two patients who were in pre-labor may be at term or preterm were scanned in the Department of Radiology for fetal lung maturity. The findings were correlated with placental grading,bi-parietal diameter, lower limb epiphyseal centers and free floating particles in amniotic fluid. Results: With gestational age ≥37 weeks, there is variation in placental grading but majority of patients showed grade III placenta. Nearly all patients with free floating particles have distal femoral epiphysis≥5 mm and proximal tibial epiphysis≥5 mm and almost all patients with biparietal diameter ≥9.0 cm showed mature lower limb epiphyseal centres. Conclusion: USG is anoninvasive, reliable and cost effective technique to reduce mortality and morbidity in neonates. When we use USG parameters to assess fetal lung maturity the priority should be given to BPD ≥9.0 cm (100%), DFE ≥5 mm (98%), PTE ≥5 mm (97.7%), grade III placenta (96.9%) and free floating particles (95.1%).
