Abstract
Objective: To determine the incidence, obstetric risk factors and perinatal outcome of placenta previa. Study design: All singleton deliveries at our institution between 1990 and 1998 complicated with placenta previa were compared with those without placenta previa. Results: Placenta previa complicated 0.38% ( n = 298) of all singleton deliveries ( n = 78 524). A back-step multiple logistic regression model found the following factors to be independently correlated with the occurrence of placenta previa: maternal age above 40 years (OR 3.1, 95% CI 2.0-4.9), infertility treatments (OR 3.1, 95% CI 1.8-5.6), a previous Cesarean section (OR 1.8, 95% CI 1.4-2.4), a history of habitual abortions (OR 1.3, 95% CI 1.3-2.7) and Jewish ethnicity (OR 1.3, 95% CI 1.1-1.8). Pregnancies complicated with placenta previa had significantly higher rates of second-trimester bleeding (OR 156.0, 95% CI 87.2-277.5), pathological presentations (OR 7.6, 95% CI 5.7-10.1), abruptio placentae (OR 13.1, 95% CI 8.2-20.7), congenital m...
目的:探讨前置胎盘的发生率、产科危险因素及围产儿结局。研究设计:将我院1990 - 1998年间所有合并前置胎盘的单胎分娩与未合并前置胎盘的单胎分娩进行比较。结果:单胎分娩中前置胎盘合并率为0.38% (n = 298);反向多元logistic回归模型发现以下因素与前置胎盘的发生独立相关:母亲年龄大于40岁(OR 3.1, 95% CI 2.0-4.9)、不孕治疗(OR 3.1, 95% CI 1.8-5.6)、既往剖宫产(OR 1.8, 95% CI 1.4-2.4)、习惯性流产史(OR 1.3, 95% CI 1.3-2.7)和犹太种族(OR 1.3, 95% CI 1.1-1.8)。妊娠合并前置胎盘的妊娠中期出血(OR 156.0, 95% CI 87.2-277.5)、病理表现(OR 7.6, 95% CI 5.7-10.1)、胎盘早剥(OR 13.1, 95% CI 8.2-20.7)、先天性早产(OR 13.1, 95% CI 8.2-20.7)的发生率明显更高。
