摘要
目的:应用三维彩色多普勒超声检测绕颈脐带螺距增加率,探讨胎儿宫内缺氧与之相关性。方法:对我院115例脐带绕颈胎儿颈部及游离部脐带螺距进行测量,计算增加率。依据胎儿监护将胎儿分为缺氧组(42例)和非缺氧组(73例)。胎儿行无应激试验,产后追踪羊水性状及产程中胎心率变化。结果:缺氧组和非缺氧组脐带螺距增加率分别为(0.37±0.07)%、(0.20±0.01)%,两者比较差异有高度统计学意义(P<0.01);缺氧组脐动脉血流收缩压与舒张压的比值(S/D)为(3.23±0.08)、羊水污染及胎心率异常的例数(23例,占54.8%)与非缺氧组脐动脉血流S/D(2.27±0.11)、羊水污染及胎心率异常的例数(13例,占17.8%)比较,差异均有统计学意义(均P<0.05)。结论:三维彩色多普勒超声检测绕颈脐带螺距增加率可及时提示胎儿宫内缺氧,为临床尽早诊断和治疗提供帮助。
Objective： To evaluate the relation between the increased ratio of pitch of screws of nuchal circular umbilical cord and fetal intrauterine anoxia by detected the increased ratio of pitch of screws of nuchal circular umbilical cord with Three-dimension dolour Doppler ultrasonography. Methods： 115 fetuses with nuchal circular umbilical cord were examined the pitch of screws of nuehal circular umbilical cord and dissociated umbilical cord, the increased ratio between them were calculated. All fetuses were divided into anoxia group （42 cases） and non-anoxia group （73 cases） according to NST Score. The fetuses were tested by non stress test （NST） in order to observe the amniotic fluid and the fetal heart rate in the course of parturition after post partum. Results： The increased ratio of anoxia group [（0.37±0.07）%] was much more than the non-anoxia group [（0.20±0.01）%] （P〈0.01）. There also were significant differences in umbilical artery blood flow parameter S/D [anoxia group was （3.23±0.08）, non-anoxia group was （2.27±0.11）], abnormal fetal heart rate and amniotic fluid [anoxia group had 23 cases （54.8%）, non-anoxia group had 13 cases （17.8%）] between the two groups （all P〈0.05）. Conclusion： The increasing ratio of pitch of screws of nuchal circular umbilical cord detected by Three-dimension eolour Doppler ultrasonography can imply fetal intrauterine anoxia in time, and can provide help for clinical early diagnosis and timely treatment.
