目的探讨副胎盘发生的危险因素及对妊娠结局的影响。方法对294例副胎盘组和正常对照组进行病例对照研究,对副胎盘发生的有关危险因素及妊娠结局进行了对比分析。结果副胎盘在单胎妊娠妇女中的发生率为1.04%。多因素Logistic回归分析发现孕龄、流产史、盆腔感染、剖宫产史、不孕和先兆子痫为副胎盘的独立危险因素。副胎盘易致新生儿早产、出生低体重儿和新生儿窒息,使剖宫产率增加。结论孕龄高、肥胖、盆腔感染、有剖宫产史、不孕和先兆子痫的孕产妇,副胎盘的发生率高。副胎盘易致早产、低体重儿和新生儿窒息,增加剖宫产率。
Objective To explore the risk factors for the incidence of paracentremia and the impact on pregnancy outcome. Methods 294 cases of paracancer group and normal control group case-control study of the incidence of palate placenta-related risk factors and pregnancy outcomes were compared. Results The incidence of secondary placenta in singleton pregnant women was 1.04%. Multivariate Logistic regression analysis found that gestational age, abortion history, pelvic infection, cesarean section history, infertility and preeclampsia were independent risk factors for the palate. Palate easily lead to neonatal premature birth, low birth weight infants and neonatal asphyxia, cesarean section rate increased. Conclusion The incidence of pregnant women with high gestational age, obesity, pelvic infection, history of cesarean section, infertility and preeclampsia is high. Parasites prone to premature birth, low birth weight infants and neonates asphyxia, increased cesarean section rate.
