【摘要】：目的研究分析中晚孕出血的原因,并探究产前超声检查对中晚孕出血妊娠结局的影响。方法选择2012年1月至2014年1月在我院待产的出现一次或多次阴道出血的中晚期妊娠产妇93例(观察组)。再随机选择同期待产的无出血症状孕妇93例(对照组)。对比两组前置胎盘等情况,进行产前超声检查后同时记录妊娠结局。结果观察组出现前置胎盘、胎盘早剥、胎盘植入、子宫破裂以及宫颈机能不全等比例均显著高于对照组。妊娠结局中观察组出现剖宫产、胎儿早产、产后出血以及子宫切除等比例高于对照组,新生儿中观察组新生儿出现低体重儿、发病、死亡的比例均显著高于对照组,差异均有统计学意义(均P0.05)。最后将前置胎盘、胎盘早剥作为产前超声诊断前置胎盘准确度达到65.59%,明显高于胎盘早剥检测的46.77%。并且观察组的漏诊率低于胎盘早剥,特异性高于胎盘早剥。结论产前超声检查能提示中晚孕出血以降低妊娠结局的不良率。
[Abstract]:Objective to study the causes of mid-late pregnancy hemorrhage and to explore the effect of prenatal ultrasound examination on pregnancy outcome of mid-late pregnancy hemorrhage. Methods from January 2012 to January 2014 93 pregnant women with one or more vaginal bleeding in our hospital were selected (observation group). 93 pregnant women with no bleeding symptoms were randomly selected for the same expectant delivery (control group). Placenta previa was compared between the two groups and pregnancy outcome was recorded simultaneously after prenatal ultrasound examination. Results the proportion of placenta previa placenta abruption placenta accreta uterine rupture and cervical dysfunction in the observation group were significantly higher than those in the control group. The rates of cesarean section, preterm delivery, postpartum hemorrhage and hysterectomy in the observation group were higher than those in the control group, while those in the observation group were significantly higher than those in the control group. The difference was statistically significant (P0.05). Finally, the accuracy of placenta previa and placental abruption was 65.599.It was significantly higher than that of 46.77 placenta abruption. The missed diagnosis rate of the observation group was lower than that of placental abruption, and the specificity was higher than that of placental abruption. Conclusion Antepartum ultrasound examination can indicate mid-late pregnancy bleeding in order to reduce the rate of unfavorable pregnancy outcome.
