Threatened miscarriage during first and second trimester and perinatal outcome

Abstract

To examine the effect of threatened miscarriage on perinatal outcome. 428 histories of preterm labour were retrospectively evaluated. RESULTS: Second-trimester threatened miscarriage was not associated with premature delivery neither with hypotrophy of newborn but increased the risk of lungs atelectasis (odds ratio 2.22). Neonates of women with first and second-trimester threatened miscarriage were more likely to have of lungs atelectasis (odds ratio 2.12), intrauterine hypoxia (odds ratio 3.0), perinatal pathology of the central nervous system (odds ratio 2.94).
