【摘要】：目的通过彩色多普勒超声对中晚孕期胎儿脐带绕颈的动态监测,了解脐带绕颈在孕期中的自然变化。方法收集2009年1月～2012年10月整个孕期在我院完成规定的超声检查并在我院住院分娩的孕妇,单胎8016胎,双胎183例366胎,并将单胎分为脐带绕颈组及无脐带绕颈组。利用超声工作站详细完整记录整个孕期超声检查次数、胎儿有无脐带绕颈及其变化情况,并将数据导出建立数据库进行分析。结果(1)单胎超声检查脐带绕颈发生率为63.51%,分娩时脐带绕颈发生率32.12%；双胎超声检查脐带绕颈发生率为18.85%。双胎的脐带绕颈发生率低于单胎(P0.05)。(2)孕期持续脐带绕颈和孕期多变化脐带绕颈与分娩时相比,前者变化率较低(P0.05)。(3)脐带绕颈组和无绕颈组的脐动脉血流S/D比值、RI值相比差异没有统计学意义(P0.05)。(4)脐带绕颈组的脐带长度比无绕颈组长(P0.05),脐带绕颈与脐带长度呈正相关(P0.05)。(5)脐带绕颈组比无绕颈组的羊水量相对较多(P0.05),脐带绕颈与羊水量呈正相关(P0.05)。(6)脐带绕颈组与无绕颈组相比围产儿预后差异无统计学意义(P0.05),但是脐带绕颈组的剖宫产率比无绕颈组高(P0.05) 结论(1)本研究通过大样本的深入研究,认为脐带绕颈的发生不可预见,整体来看脐带绕颈多集中在中晚孕期。部分胎儿脐带绕颈可自行宫内复位。(2)孕期持续脐带绕颈和孕期多变化脐带绕颈与分娩时相比,前者变化率较低。(3)脐带绕颈的发生与脐带长度、羊水量有一定的相关性。
[Abstract]:Objective to investigate the natural changes of umbilical cord around neck during pregnancy by color Doppler ultrasound (CDFI). Methods from January 2009 to October 2012, pregnant women who completed the prescribed ultrasound examination in our hospital and delivered in our hospital during the whole pregnancy from January 2009 to October 2012 were collected. The single pregnancy was 8016, and the twin pregnancy was 8016. The single fetus was divided into umbilical cord around neck group and no umbilical cord around neck group. Ultrasonic workstation was used to record the times of ultrasound examination in the whole pregnancy, the fetal umbilical cord around neck and its changes, and the data were exported to establish a database for analysis. Results (1) the incidence of umbilical cord around neck was 63.51in single fetus, 32.12 in parturition, 18.85 in twinning ultrasound. The incidence of umbilical cord around neck in twin pregnancy was lower than that in single fetus (P0.05. 2) the rate of continuous umbilical cord around neck and pregnancy during pregnancy was lower than that in single fetus. Compared with parturition, the umbilical cord around the neck of multiple phase changes, The change rate of the former was lower than that of the control group (P0.05. 3) there was no significant difference in the S- D ratio of umbilical artery blood flow between the cord around neck group and the non-circumscribed neck group. There was no significant difference in the length of umbilical cord between the two groups (P0.05. 0. 05) the length of umbilical cord around the neck group was higher than that in the non-circumscribed neck group (P 0. 05%), and the length of umbilical cord around neck and umbilical cord length was positively correlated with the length of umbilical cord. The amniotic fluid volume in the cord around neck group was higher than that in the non-wound neck group, and there was a positive correlation between the amniotic fluid volume and the umbilical cord around neck group. (P0.05) there was no significant difference in the prognosis of perinatal infants between the cord around neck group and the non-wound neck group, but there was no significant difference between the umbilical cord around the neck group and the amniotic fluid volume in the umbilical cord around neck group (P0.05), but there was no significant difference between the umbilical cord around neck group and the non-wound neck group in the prognosis of perinatal infants. The yield was higher than that without neck winding (P0.05). Conclusion 1) in this study, it is considered that the occurrence of umbilical cord around the neck is unpredictable through a large sample of in-depth studies. On the whole, most of the umbilical cord around neck is concentrated in the middle and late pregnancy. Some fetal umbilical cord around neck can be reduced by itself. 2) continuous umbilical cord around neck during pregnancy and changes in umbilical cord around neck during pregnancy are compared with those in parturition. The change rate of the former was lower. 3) the occurrence of umbilical cord around the neck was correlated with the length of umbilical cord and amniotic fluid.
