Abstract:
Objective To explore the clinical value of false positive of Down’ s Syndrome Screening for premature rupture of membranes in the second trimester of pregnancy. Methods From Jan. 2009 to Jul. 2013, there were 321 cases who were in the second trimester of high risk pregnancy recieved Down’ s Syndrome Screening. Their fetals have been excluded chromosome or organ abnormality, and there was no fetal organ structure abnormal through sequence prenatal ultrasound examinations. Results of their pregnancy have been followed-up, and pregnancy outcomes of 346 cases who were of low risk were followed-up at the same time. Results Among the 321 cases, there were 14 ca-ses of abortion because of PROM ( gestational age less than 28 weeks);17 cases of premature delivery because of PROM, including 9 cases whose gestational age were from 28 to 34 weeks and 8 cases whose gestational age were from 34 weeks to 37 weeks;and 7 cases of neonatal asphyxia. In the low risk group, abortion because of PROM occured in 6 cases before 28 weeks, 3 cases between 28 to 34 weeks, and 4 ca-ses between 34 to 37 weeks, and neonatal asphyxia occured in 3 cases. Conclusion Comparing with Down’ s screening false positive preg-nant women and the low risk group, the false positive group have a higher occurrence of PROM, Down’ s screening is a potential high risk in-dex as a predictor of PROM.
