Can Ultrasound Replace Amniocentesis for Confirming Fetal Lung Maturation Among Premature Fetuses?

The purpose of this study is to measure prenatally with ultrasound the intratracheal flow volume displaced during breathing cycle in premature fetuses and to check whether a relationship exists between the inspired fluid and fetal lung maturation.

Inclusion Criteria:

• Women delivering between 27 to 37 weeks.
• Women undergoing amniocentesis for determining fetal lung maturity between 27 to 37 weeks.

Exclusion Criteria:

• Major fetal malformation.
• Oligohydramnios or rupture of membranes diagnosed before 24 weeks of gestation.
