[Ultrasound evaluation of fetal lung maturity in imminent preterm labor cases]

The development of ultrasound examination lets us perform the biophysical assessment of fetus lungs. From 1986, at the Ivth Clinic of Obstetrics and Gynecology in Tychy, examinations of fetus lung were performed with Siemens and Bruel & Kjaer real-time ultrasonographic equipped. The elasticity of fetal lung (DLS--dynamic lung score) was estimated by taking a transversal section through the fetal chest in a plane at fetal in a plane at fetal heart and presented in 3-grade scale: I-grade--lack of elasticity (immaturity of lungs), II-grade--non complete elasticity, III-grade--normal elasticity (maturity of lungs).
