ObjectiveTo explore the influencing factors, clinical manifestations and pregnancy outcomes of premature delivery complicated with placental abruption.

MethodsOne hundred and eleven patients with placental abruption were divided into the preterm delivery group(n=43) and full-term pregnancy group(n=68) according to the gestational weeks.The related causes, clinical manifestations, and maternal and infant outcomes were compared between two groups.

ResultsThe differences of the age and whether primipara or not between two groups were not statistically significant(P>0.05), and the differences of the scar uterine and mediastinal uterine rates between two groups were statistically significant(P < 0.05).The vaginal bleeding, abdominal pain and abnormal rate of ultrasound examination in preterm delivery group were higher than those in full-term pregnancy group(P < 0.05 to P < 0.01), and the hemorrhagic amniotic fluid rate in preterm delivery group was lower than that in full-term pregnancy group(P < 0.05).The incidence rates of neonatal asphyxia and perinatal death in preterm delivery group were higher than those in full-term pregnancy group(P < 0.05 and P < 0.01).

ConclusionsThe influencing factors and clinical manifestations of placental abruption are diverse, and the comprehensive judgment, early recognition and intervention are needed to improve the maternal and infant outcomes.
