目的评价经阴道超声检测孕妇宫颈情况结合血β-HCG值预测早产的价值。方法采用经阴道超声检测146例先兆早产孕妇的宫颈长度及有无漏斗形成,同时检测血β-HCG值,并追踪结果。结果 146例先兆流产孕妇中,62例发生早产,84例未发生早产。早产组宫颈长度为(22.3±5.8)mm,明显短于非早产组(33.9±7.1)mm。早产组62例孕妇有56例有漏斗形成,漏斗形成率为90.3%,非早产组84例孕妇中有5例形成漏斗,漏斗形成率为5.9%,两组对比差异有统计学意义(P<0.05)。早产组孕妇血清β-HCG为(28.8±9.6)μg/L,高于非早产组(16.6±5.1)μg/L。结论经阴道超声检测宫颈的长度及有无漏斗形成对孕妇早产的发生有预测价值,同时早产的发生与血β-HCG水平增高有关。两者联合,对早产的预测有重要的临床价值。
Objective To evaluate the value of transvaginal ultrasonography in detecting pregnant women ’s cervical condition combined with blood β-HCG value to predict preterm labor. Methods Transvaginal ultrasonography was used to detect the length of the cervix and the presence or absence of funnel in 146 pregnant women with threatened preterm labor. The blood β-HCG levels were also measured and the results were tracked. Results In 146 cases of threatened abortion pregnant women, 62 cases of premature birth, 84 cases did not occur premature birth. The length of the cervix in premature labor was (22.3 ± 5.8) mm, significantly shorter than that in nonpremature (33.9 ± 7.1) mm. Premature labor group 62 pregnant women 56 cases of funnel formation, funnel formation rate was 90.3%, non-premature 84 cases of pregnant women, 5 cases of funnel formation, funnel formation rate was 5.9%, the difference between the two groups was statistically significant (P < 0.05). The serum level of β-HCG in preterm labor group was (28.8 ± 9.6) μg / L, higher than that in non-preterm group (16.6 ± 5.1) μg / L. Conclusion Transvaginal ultrasonography to detect the length of the cervix and whether the formation of funnel on the occurrence of preterm birth of pregnant women have predictive value, while the occurrence of preterm birth and increased blood levels of β-HCG. Combination of the two, the prediction of preterm birth has important clinical value.
