Placenta Abruption: Clinical Analysis of 112 Cases

Objective To explore the etiology and clinical characteristic of abruptio placentae and its impact on mother and infant and the key points of early diagnosis. Methods We reviewed 112 cases of abruptio placentae from Jan.2001 to June 2009. Results Pregnancy-induced hypertension was the main cause of abruptio placentae accounting for 50.0%, with a significant difference compared with other causes (P0.05).The accident rate of placental apolexy in severe abruptio placentae was 13.3% while that of DIC, postpartum haemorrhagia,neonatal asphyxia and perinatal mortality was 10.0%, 53.3%, 43.3% and 6.7% respectively,all of which were higher than those in mild abruptio placentae (P 0.05).The missed diagnosis rate of mild abruptio placentae by using B-ultrasonography was 76.9% and that of severe abruptio placentae was 43.3%(P0.05). Conclusion It is helpful to diagnose placental abruption early by using clinical symptoms and B ultrasound. The early management can decrease the mortality of pregnancy and perinatal period.
