B超测量宫颈形态学指标预测早产及分娩方式的临床应用研究

摘要

目的：探讨B超测量宫颈形态学指标预测早产及分娩方式的关系。方法：收集2011年1月～2012年12月在我院检查的单胎和双胎初产妇246例，年龄20～40岁，平均年龄(30±10)岁,孕龄24～37周。以分娩结局随机分为3组，足月分娩组(A组)246例,早产组(B组)246例，先兆早产组(C组)246例。A组以宫颈长度分娩方式：>36mm组(D组)62例，<36mm组(E组)122例。孕期内常规超声观察宫颈形态变化，测量宫颈长度，并随访妊娠结局。结果：A组产妇平均宫颈长度显著大于B组（P<0.01）和C组（P<0.01），C组平均宫颈长度显著大于B组（P<0.01）；产妇剖宫产率： E组明显小于D组（P<0.01）。结论：宫颈长度可作为预测早产和剖宫产的可行性指标。%Objective:To investigate the B-ultrasound Measurement of cervical and morphological predictor of preterm delivery mode of relationship. Methods:January 2011~December 2012 in our hospital to check tires and twin single Primipara 246 cases, aged 20 to 40 years, mean age (30 ± 10) years of age, 24 to 37 weeks gestational age. In birth outcomes were randomly divided into three groups, term delivery group (A) 246 cases of preterm group (group B) 246 cases of threatened preterm labor group (group C) 246 cases. A group with cervical length delivery mode:>36mm (group D) 62 cases,<36mm group (E) of 122 cases. Routine ultrasound during pregnancy cervical morphological changes observed, the measurement of cervical length and fol ow-up pregnancy outcome. Results:A group of mothers was signiifcantly greater than the average cervical length group B (P<0.01) and group C (P<0.01), group C was signiifcantly greater than the average cervical length group B (P<0.01);maternal cesarean section rate:E were signiifcantly Smal er D group (P<0.01). Conclusions:Cervical length as a predictor of preterm delivery and cesarean feasibility indicators.
