剖宫产术后年限与子宫下段厚度关系对分娩方式选择研究

摘要

目的 探讨应用B超及剖宫产时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意义.方法 应用B超及剖宫产时观察376例不同剖宫产术后时间孕妇的子宫下段厚度,并对比分析二者差异.结果 B超和剖宫产时观察妊娠晚期子宫下段厚度差异无明显差异(P＞ 0.05),且子宫下段厚度≥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,与剖宫产时观察厚度无明显差异,对剖宫产术后妊娠患者选择分娩方式具有重要指导意义,能最大限度降低先兆子宫破裂的发生率.%Objective To explore the instructive significance of getting the lower uterine segment thickness in late pregnancy by B-ultrasound and during cesarean section for delivery way selection.Methods Used B-ultrasound to observed the lower uterine segment thickness in 376 pregnant women with different post-cesarean-section time.Meanwhile,observed the thickness during cesarean section.Compared the differences between them.Results The lower uterine segment thickness in late pregnancy observed by B-ultrasound had no significant difference from that observed during cesarean section( P＞ 0.05 ).The pregnant women with lower uterine segment thickness ≥ 2 mm could try to deliver vaginally.Conclusion Using B-ultrasound examine the thickness of lower uterine segment has no trauma,correct result,no difference from that observed during cesarean section,important instructive significance on selecting delivery way for post-cesarean-section pregnant patients,and can reduce the incidence of uterine rupture maximally.
