目的探讨B超检查对妊娠疤痕子宫破裂中的临床预测价值分析。方法选择我院2012年4月至2015年1月收治的76例疤痕子宫孕妇为研究对象,对所有孕妇实施B超检查,对不同孕周孕妇的超声检测结果进行分析,并对不同子宫下段厚度患者的生产方式及生产结局进行分析。结果孕妇妊娠32~34及35~36周时,其子宫下段厚度明显较妊娠37~38、39~40周时高,差异存在统计学意义(P<0.05);妊娠37~38周时的子宫下段厚度与39~40周时无差异(P>0.05);经B超预测疤痕愈合为Ⅲ级患者,其剖宫产率显著较2级高(P<0.05);2级剖宫产率则明显高于1级孕妇,差异存在统计学意义(P<0.05);所有孕妇均为妊娠32周后开始出现子宫下段厚度变化,B超下发现有先兆子宫破裂、子宫破裂为11例,经手术证实出现子宫破裂为12例,B超诊断符合率为91.67%。结论疤痕子宫再次妊娠时,可通过B超监测判断子宫下段厚度,从而起到子宫破裂良好预测效果,值得临床推广。
Objective To investigate the clinical predictive value of B-ultrasound in detecting uterine rupture in pregnancy. Methods A total of 76 cases of uterine uterus treated in our hospital from April 2012 to January 2015 were selected as the study objects. All pregnant women underwent B-mode ultrasonography. Ultrasound results of pregnant women at different gestational ages were analyzed. Patient’s mode of production and the outcome of the analysis. Results The pregnant women at 32-34 and 35-36 weeks of gestation had significantly lower uterine thickness than those at 37-38 and 39-40 weeks of gestation (P <0.05), and those at 37-38 weeks of gestation The thickness of the lower segment had no difference with that of 39-40 weeks (P> 0.05). The rate of cesarean section was significantly higher than that of grade 2 (P <0.05) (P <0.05). All pregnant women began to have thickness changes of the lower uterine segment after 32 weeks of gestation. There were 11 cases of uterine rupture and 11 cases of uterine rupture. Confirmed the appearance of uterine rupture in 12 cases, B ultrasound diagnosis was 91.67%. Conclusions When uterine scar pregnancy again, the thickness of lower uterine segment can be judged by B-ultrasound, which can predict the uterine rupture well and is worthy of clinical promotion.
