摘　　要：目的观察不同宫颈长度预测早产的准确性,探究基层医院采用阴道B超测量宫颈长度在预测早产中的应用价值。方法观察90例孕周<37周孕妇孕妇不同孕周宫颈长度,以及经阴道超声测量宫颈长度预测早产的准确性。结果以宫颈25mm为临界值,共有65例孕妇宫颈长度≥25mm,其中足月产60例(92.31%),早产5例(7.69%);宫颈长度<25mm共25例,其中足月产9例(36.00%),早产16例(64.00%)。宫颈长度<25mm的孕妇早产率明显高于≥25mm的孕妇(χ~2=32.0010,P<0.0001),差异具有统计学意义。宫颈长度<25mm敏感度为0.7619,特异性为0.8696,约登指数为0.6315,诊断符合率84.44%。结论经阴道B超测量宫颈长度预测早产准确性较好,适合基层医院临床使用。ObjectiveTo observe the accuracy of different cervical lengths in predicting preterm birth, and to explore the value of using transvaginal B-ultrasound to measure cervical length in predicting preterm delivery. MethodsThecervical length of 90 pregnant women of less than 37 gestational weeks was measured by transvaginal B-ultrasound.Theaccuracy of different cervical lengths in predicting preterm birth was observed. ResultsAmong the 65 pregnant women with cervical length ≥25mm, there were 60 cases (92.31%) of full-term birth and 5 cases (7.69%) with preterm birth. Among the 25 cases with cervical length <25mm, there were 9 cases (36.00%)of full-term birth and 16 cases (64%)of preterm birth. The preterm birth rate of pregnant women with cervical length <25mm was significantly higher than that of pregnant women with cervical length≥25mm, with statistically significant difference (χ^2=32.0010,P<0.0001). Thesensitivity,specificity,Youden index and diagnostic compliance rate of cervical length <25mm was 0.7619, 0.8696, 0.6315and 84.44% respectively. ConclusionsThe measurement of cervical length by transvaginal B-ultrasound is a good predictor of premature birth and suitable for clinical use in primary hospitals.
