Abstract:
Objective To study the sonographic features of fetal lung in normal and preeclampic pregnancies,with follow-up on the occurrence of neonatal respiratory distress syndrome (NRDS),as well as,examine the effects of preeclampsia (PE) on fetal lung maturity (FLM).Methods We collected data from 140 cases during the early pregnancy period (29 to ＜34 weeks),100 cases during the late pregnancy period (34 to 39 weeks),as well as 240 cases of normal pregnancies with the same gestational ages for the contwl group.Data included the parameters of fetal lung maturity measured by ultrasound and the incidence of NRDS postpartum.We analyzed the effects of PE on fetal lung maturity.Results The right fetal lung from the early onset PE group was significantly smaller than that of the normal group.There was no difference in the right lung area between the PE group and the normal group of the same gestational age.Compared with the normal group of the same gestational age,the LHR group had no difference in the early and late PE groups.The acceleration time/ejection time of the main pulmonary artery in the early and late PE group was significantly higher than that of the normal group.There was no difference in the incidence of NRDS among all the groups of the same gestational age.Conclusion PE has no significant effect on fetal lung function or maturation of the pulmonary tissues.Lung maturation may precede the same gestational age without PE.
