目的研究分析前置胎盘合并瘢痕子宫对母婴妊娠结局的影响。方法 100例前置胎盘产妇,根据是否为瘢痕子宫划分为研究组和对照组,每组50例,研究组为前置胎盘合并瘢痕子宫产妇,对照组为单纯前置胎盘产妇,对两组产妇产后出血量、胎盘植入以及子宫切除率等情况进行观察对比。结果研究组产后出血52.0%、胎盘植入40.0%、术中出血量(1627.3±285.6)ml以及手术时间(67.9±11.1)min相比于对照组12.0%、8.0%、(861.4±186.9)ml以及(29.7±4.4)min明显更高,差异具有统计学意义(P<0.05);研究组子宫切除率10.0%、休克10.0%、血管内凝血12.0%相比于对照组0、4.0%、2.0%明显更高,差异具有统计学意义(P<0.05);研究组新生儿早产58.0%相比于对照组2.0%明显更高,差异具有统计学意义(P<0.05),两组新生儿窘迫、死亡对比,差异无统计学意义(P>0.05)。结论前置胎盘为妊娠晚期出现的一种严重并发症,母婴妊娠结局受前置胎盘合并瘢痕子宫影响很大,临床极易并发产后出血、胎盘植入等并发症,产前应当采取重点关注,必要时可进行子宫切除处理。 Objective To study the effect of placenta previa combined with uterus on maternal and fetal pregnancy outcomes. Methods 100 cases of placenta previa, according to whether the uterus is divided into study group and control group, 50 cases in each group, the study group was placenta previa with uterine scar, the control group was simple placenta previa, the two groups of mothers Postpartum hemorrhage, placenta accreta and hysterectomy rates were observed and compared. Results In the study group, postpartum hemorrhage was 52.0%, placenta accreta was 40.0%, blood loss (1627.3 ± 285.6) ml and operation time (67.9 ± 11.1) min were 12.0%, 8.0%, (861.4 ± 186.9) ml (29.7 ± 4.4) min, the difference was statistically significant (P <0.05). In the study group, the hysterectomy rate was 10.0%, the shock rate was 10.0%, the intravascular coagulation rate was 12.0% (P <0.05). Compared with the control group, 58.0% in the study group was significantly higher than 2.0% in the control group, the difference was statistically significant (P <0.05), the two groups of neonatal distress There was no significant difference between the two groups (P> 0.05). Conclusions The placenta previa is a serious complication in the third trimester of pregnancy. The maternal and fetal pregnancy outcome is greatly influenced by the placenta accreta with the scar uterus. It is very easy to be complicated by post-partum bleeding, placenta accreta and other complications. Prenatal care should be focused , If necessary, hysterectomy.
