The Role of Fetal Ductus Arteriosus in Predicting Spontaneous Preterm Birth
NCT03073512 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL
Last updated 2023-12-12
Summary
Preterm birth still remains a major cause of perinatal morbidity and mortality worldwide. The exact mechanism stimulating term and preterm births in humans is still unknown. Prostaglandins, by mediating cervical ripening and early stimulation of myometrial contractions, are likely to play a major role in the parturition process. Much of the unique fetal circulation is facilitated by the ductus arteriosus. Patency of the ductus arteriosus in utero is primarily maintained via prostaglandins which are highly expressed by smooth muscle cells located in the media of the ductus arteriosus. The primary objective of this study is to prospectively assess whether any changes in the fetal ductus arteriosus parameters exist at 32 weeks' gestation. The secondary objective is to investigate whether there is an association between the ductus arteriosus parameters and the time to delivery interval at 32 weeks' gestation.
