Clinical research on the antenatal hemorrhage of placenta previa of 158 patients in the later stages of pregnancy

目的:探讨前置胎盘产前大出血的相关因素,总结紧急处理措施。方法:对诊断前置胎盘出血158例患者进行回顾性分析。结果:剖宫产术147例(93.04%),阴道分娩11例(6.96%)。158例中1例死胎,新生儿窒息7例(重度窒息1例),新生儿预后均良好。2例因产后大出血切除子宫(其中1例为胎盘植入),其余均母婴安全。结论:剖宫产术是处理晚孕期前置胎盘大出血的主要手段,可以最大限度地保证母婴安全。

Methods： 158 patients diagnosed as antenatal hemorrhage of placenta previa were analyzed retrospectively. Results： Of all the 158 patients, 147 patients （93.04%） performed cesarean section, and the other 11 cases （6.96%） performed vaginal de- livery. All newborns including 7 cases of suffocation newborns （one was a severe suffocation case） had good prognosis ex- cept one death. 2 patients were performed hysterectomy for postpartum hemorrhage （one for placenta accreta）, and the oth- ers were safe.
