B超检查对剖宫产术后分娩方式选择的指导作用

The guiding role of B-ultrasound examination on delivery methods selection for patients with caesarean section

目的探讨剖宫产时应用B超观察妊娠晚期子宫下段厚度对剖宫产术后分娩方式选择的指导作用。方法剖宫产时直视下观察和应用B超观察妊娠晚期子宫下段厚度,并对比分析二者的差异。结果直视下观察和应用B超观察妊娠晚期子宫下段厚度,两种方法无明显差异(P>0.05),子宫下段厚度≥2 mm者可行阴道试产。结论采用B超检测子宫下段厚度无创伤且结果准确,与剖宫产时直视下观察子宫下段厚度无明显差异,对剖宫产术后妊娠患者选择分娩方式具有重要的指导意义,能最大限度地降低先兆子宫破裂的发生率。

Objective To explore the directive function of getting the lower uterine segment thickness in late pregnancy by B-ultrasound examination and during caesarean section for delivery way selection. Methods the lower uterine segment thickness in 24 pregnant women were observed with B-ultrasound and orthophoria, the difference was studied .Results The lower uterine segment thickness in late pregnancy observed was no significant statistical differences between B-ultrasound and operation （/9〉0.05）. The pregnant women with lower uterine segment thickness 2 turn could try to deliver vaginally. Conclusion Using B-ultrasound to examine the lower uterine segment thickness has no trauma, correct result and no significant statistical differences from that observed during caesarean section. It has important guiding significance on selection delivery way for post-caesarean-section pregnant patients, and can reduce the incidence of uterine rupture maximally.
