目的分析前置胎盘合并瘢痕子宫2次妊娠的危险因素和对妊娠结局的影响。方法选择前置胎盘合并瘢痕子宫,发生2次妊娠的孕产妇38例作为观察组,前置胎盘非瘢痕子宫,2次妊娠的孕产妇53例作为对照组,比较两组妊娠结局和对新生儿的影响。结果观察组剖宫产率100%,对照组阴道分娩率33.96%,剖宫产率66.04%,两组差异有统计学意义。观察组并发症发生率高,与对照组比较,差异有统计学意义,对照组有优势。观察组妊娠终止时间(32.33±2.14)周,术中术后出血量(435.50±15.50)ml,差异有统计学意义,对照组有优势。新生儿并发症发生率和Apgar评分,两组差异无统计学意义。结论前置胎盘合并瘢痕子宫再次妊娠危险性较大,孕期和产后并发症高,为降低产后出血和子宫切除率,掌握剖宫产手术指征,进行择期手术更适宜。
Objective To analyze the risk factors of pregnancy in placenta previa with placenta previa and its effect on pregnancy outcome. Methods 38 cases of pregnant women with 2 pregnancies in placenta previa combined with scar pregnancy were selected as observation group, 53 cases of pregnant women with non-scarring placenta previa and 2 pregnancies as control group. Pregnancy outcome and neonatal Impact. Results The rate of cesarean section was 100% in the observation group, 33.96% in the control group and 66.04% in the control group. There was significant difference between the two groups. The incidence of complications in the observation group was high, compared with the control group, the difference was statistically significant, the control group has the advantage. The observation group’s termination of pregnancy (32.33 ± 2.14) weeks, postoperative blood loss (435.50 ± 15.50) ml, the difference was statistically significant, the control group has the advantage. The incidence of neonatal complications and Apgar score, the two groups showed no significant difference. Conclusions There is a high risk of re-pregnancy in placenta previa with placental uterus, high pregnancy and postpartum complications. To reduce postpartum hemorrhage and hysterectomy rate, it is more appropriate to master cesarean section indications and elective surgery.
