Relationship Between Peak Systolic Velocity in Pulmonary Artery Color Doppler and Neonatal Respiratory Outcomes in Fetal Growth Restriction With Abnormal Fetoplacental Circulation: A Prospective Cohort Study

Objectives: Newborns with fetal growth restriction (FGR) are at a high risk of prenatal mortality and morbidity compared to infants appropriate intrauterine growth. The importance Doppler ultrasound as non-invasive method for estimating the pulmonary artery pressure (PAP) in newborns adults has been mentioned many studies. This study investigated relationship between peak systolic velocity color neonatal respiratory outcomes FGR abnormal fetoplacental circulation. Materials Methods: In this prospective cohort study, 60 pregnant women gestational age 32-37 weeks were studied two groups: group I (women fetus suspected according assessment) II normal pregnancy). All underwent artery, umbilical middle cerebral venous ductus. pick (PSV) trunk was evaluated all participants. After delivery, birth. Finally, variables included age, estimated weight based on Hadlock table, amniotic fluid index, maternal parity, pulsatility index (PI), PI, maximum (PV), ratio, number admitted newborn intensive care unit (NICU) due distress groups. Results: Our results showed significant association PI fetuses rate early NICU hospitalization higher than diseases, well need oxygen continuous positive airway (CPAP). Conclusions: Pulmonary can be effective diagnosing embryos during pregnancy making necessary predictions reduce these infants.
