The Clinical Value of Predicting Premature Birth by to Monitor Cervical withUltrasonography and to test the fetal Fibronectin / 实用放射学杂志

ABSTRACT

Objective To evaluate the relationship between the cervical length,the test of fetal fibronectin and premature birth in pregnant woman.Methods Fetal fibronectin in sample of cervical secretion was tested using the reagent box of FFN manufactured by the ADEIA company of the United States and enzyme-labeled immunosorbent assay(ELISA) methods in 110 pregnant women.They were divided into two groupsfirst group,there were 60 cases who had symptom of aura prematurity and cervical lengths ≤30 mm monitored by trans-perineum ultrasound.second group was 50 normal pregnant women.Results The postive rate of fetal fibronectin was higher significantly in first group than that in second group.Conclusion The measurement of cervical lengths by the trans-perineum ultrasound and the test of Fetal fibronectin in pregnant women who has symptom of aura prematurity are of certain clinical value in predicting preterm birth.
