| 目的 探讨经会阴部超声测量子宫宫颈前角（anterior uterocervical angle，AUCA）预测初产妇足月分娩发动时间的临床价值。方法 选取于2019年1月至2020年12月在南京医科大学附属无锡市人民医院孕39周行经会阴部超声测量AUCA且随访至分娩结果的226例初产妇，其中孕41周后发动分娩或仍未发动分娩而行人工干预的孕妇为分娩发动延迟组，孕41周前自然发动分娩的孕初产妇为对照组。比较两组AUCA的差异，绘制受试者工作特征曲线（receiver operating characteristic, ROC）评价AUCA预测分娩发动延迟的诊断效能。结果 226例初产妇中分娩发动延迟组76例，对照组150例。分娩发动延迟组和对照组AUCA分别为（ 92.6±10.9 ）°和（110.2±12.7）°，两组比较差异有统计学意义（P＜0.05）；AUCA预测分娩发动延迟ROC曲线下面积为0.84，以100.2°为最佳截断值，其诊断敏感性、特异性、阳性预测值、阴性预测值及准确率分别为78.9%（68/76）、86.7%（130/150）、77.3%（68/88）、94.2%（130/138）和87.6%（198/226）。结论 分娩发动延迟初产妇的AUCA小于正常时间发动分娩初产妇，AUCA有可能作为预测分娩发动延迟的指标。 |

| Abstract: |
| Abstract Objective To explore the clinical value of transperineal ultrasound measurement of the anterior uterocervical angle (AUCA) in predicting the onset time of full-term delivery of primipara. Methods 226 primiparas were selected from January 2019 to December 2020 in Wuxi People’s Hospital affiliated to Nanjing Medical University who underwent perineal ultrasound measurement of AUCA at 39 weeks of gestation and followed up to the delivery results. Among them, delivery was initiated after 41 weeks of gestation or still Pregnant women who underwent manual intervention without initiating labor were included in the delayed labor initiation group, and primiparous women who naturally started labor before 41 weeks of gestation were in the control group. Compare the difference of AUCA between the two groups, draw receiver operating characteristic curve (receiver operating characteristic, ROC) to evaluate the diagnostic efficacy of AUCA in predicting delivery delay. Results Among 226 primiparous women, 76 cases were in the delayed delivery group and 150 cases were in the control group. The AUCA of the delayed labor onset group and the control group were (92.6±10.9)° and (110.2±12.7)°, respectively. The difference between the two groups was statistically significant (P<0.05); AUCA predicted the area under the ROC curve for the delayed onset of labor was 0.84, Taking 100.2° as the best cut-off value, its diagnostic sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate were 78.9% (68/76), 86.7% (130/150), and 77.3% (68/ 88), 94.2% (130/138) and 87.6% (198/226). Conclusion The AUCA of primiparas with delayed onset of delivery is less than that of primiparas with delayed onset of delivery. AUCA may be used as an indicator of delayed onset of delivery. |
