目的　探讨胎盘早剥早期诊断指标及减少误诊与漏诊方法。方法　对分娩前高度怀疑胎盘早剥 ,而产后得到证实的 72例患者的临床资料进行分析。结果　产科并发症为胎盘早剥的高危因素 ;子宫敏感性增高及胎心改变是出现最早、最普遍的现象 ,发生率分别为 97.78%和 94 .4 4 % ;动态观察过程中子宫局限性压痛可从无到有 ,从不明显到明显 ,最终阳性率达 90 .2 8% ;B超检查阳性率仅为 77.78%。结论　依据早期特征性表现即可及早诊断胎盘早剥 Objective To explore the early diagnosis of placental abruption and reduce misdiagnosis and missed diagnosis. Methods The clinical data of 72 patients with highly suspected placental abruption prior to delivery before delivery were confirmed. Results Obstetric complications were the risk factors for placental abruption. Uterine sensitivity and fetal heart rate changes were the earliest and most common phenomenon, the incidence rates were 97.78% and 94.44% respectively. Uterine localized tenderness From scratch, from no obvious to obvious, the final positive rate of 90.28%; B-positive rate of only 77.78%. Conclusion Early diagnosis of placental abruption based on early characterization
