【Abstract】Objective To analyze the clinical significance of placenta location in placental abruption. Methods The clinical data of patients with placental abruption in Chengdu women and children's Hospital were collected from January 2012 to December 2016. The patients were divided into anterior placenta group and posterior placenta group according to placental location. The clinical features and outcome of the two groups were retrospectively compared. Results Time interval（between onset of symptoms and Csection）of anterior placenta group was shorter than that of posterior placenta group（1.64±1.52h vs 3.22±2.11h）. The rate of correct diagnosis before operation of anterior placenta group was higher than that of posterior placenta group（75.5% vs 61.4%）. Rate of postpartum hemorrhage anterior placenta group was less than that posterior placenta group（523.8±114.4ml vs 749.6±181.7 ml）. The incidence of postpartum hemorrhage anterior placenta group was less than that posterior placenta group（32.7% vs 47.0%）. The incidence of neonatal asphyxia in anterior placenta group was less than that posterior placenta group（27.7％vs42.2％）. The rate of neonates admitted in NICU anterior placenta group was less than that posterior placenta group（31.2％vs 45.9％）. Above all, the differences were statistically significant（P＜0.05）. There were no differences between the two groups in incidences of abdominal pain, vaginal bleeding, uterine apoplexy, and fetal weight, perinatal mortality（P＞0.05）. Conclusion Clinical symptoms of posterior placenta placental abruption were atypical. More attention should be paid to the patients with posterior placental location, in order to make correct diagnosis and quick treatment, thus improve the outcomes of maternalfetal prognosis．
