目的:探讨分析疤痕子宫再次妊娠出现前置胎盘的临床结局。方法:选取疤痕子宫再次妊娠出现前置胎盘的孕产妇作为观察组(20例),选择同期收治的疤痕子宫再次妊娠孕产妇(40例)为对照组,对两组孕产妇的分娩时间,2h内产后出血量,子宫切除率,新生儿窒息率进行对比分析。结果:观察组患者分娩时间和2h内产后出血量分别为(74.7±12.5)min、(525.6±27.3)ml,分别高于对照组的(45.8±9.5)min、(343.6±25.5)ml;观察组患者在产后子宫切除率和新生儿窒息率分别为20.0%(4/20)、15.0%(6/40),也均分别高于对照组的10.0%(2/20)、7.5%(3/20),以上各观察指标间差异均具有统计学意义(均P<0.05)。结论:疤痕子宫再次妊娠出现前置胎盘的孕产妇出现分娩时间延长,2h内产后出血量增多,在产后出现子宫切除率和新生儿窒息的风险会更高。
Objective: To investigate the clinical outcome of placenta previa pregnancy placenta re-pregnancy. Methods: Pregnant women with placental uterus and placenta previa were selected as observation group (20 cases). Pregnant women with uterine scar (40 cases) who were treated at the same period were selected as the control group. The time of labor, Within the amount of postpartum hemorrhage, hysterectomy, neonatal asphyxia comparative analysis. Results: The delivery time and the amount of postpartum hemorrhage in the observation group were (74.7 ± 12.5) min and (525.6 ± 27.3) ml, respectively, higher than that in the control group (45.8 ± 9.5) min and (343.6 ± 25.5) ml, respectively The rate of postpartum hysterectomy and neonatal asphyxia were 20.0% (4/20) and 15.0% (6/40) respectively, which were also higher than those in control group (10.0%, 7.5%, 3 / 20), the above differences between the various indicators were statistically significant (P <0.05). CONCLUSION: Maternal recurrence of placenta previa with placenta previa appears to prolong the time of delivery and increase the amount of postpartum hemorrhage within 2 hours. The risk of hysterectomy and neonatal asphyxia will be higher after birth.
