| 目的 探讨经会阴超声测量宫颈长度及形态对早产预测的临床研究效果。方法 选取有自发性早产高危因素的孕24～34周孕妇54例,行会阴超声测量宫颈长度及内口宽度,随访妊娠结局,分析妊娠结局与宫颈长度及形态之间的相关性。结果 54例有先兆早产征象的孕妇有16例,其发生率为29.6%,将病人分为两组,先兆早产组16例及非先兆早产组38例；先兆早产组的宫颈长度明显短于非先兆早产组(P＜0.05),先兆早产组的宫颈内口宽度明显长于非先兆早产组(P＜0.05),不同宫颈长度的先兆早产发生率不同,差异有统计学意义(P＜0.05),其中,宫颈长度＜10 mm的孕妇先兆早产的发生率显著高于宫颈长度≥10 mm的孕妇(P＜0.01)。结论 经会阴超声测量宫颈长度及形态的检测是一种客观、有效对早产预测的方法,宫颈长度缩短、宫颈内口宽度增长是早产高风险指标,该方法灵敏度高,有望成为临床早产预测的重要指标。 |

| Objective To investigate the effect of perineal ultrasonography on measuring the length and shape of cervix in predicting preterm labor.Methods Fifty-four pregnant women with gestational age of 24 to 34 weeks were selected.The length of the cervix and the width of the mouth were measured by perineal ultrasonography.The outcome of pregnancy was followed up.The correlation between pregnancy outcome and cervical length and shape was analyzed.Results There were 16 patients with signs of threatened preterm labor,the incidence of which was 29.6%.The patients were assigned into two groups:16 cases of threatened preterm labor group and 38 cases without threatened preterm labor group.The cervical length of threatened preterm labor group was significantly shorter than that without(P＜0.05).The cervical width of threatened preterm labor group was significantly broader than that without (P<0.05).There was significant difference in the incidence of threatened preterm delivery between different cervical lengths (P<0.05),and the difference was significant (P<0.05).The incidence of threatened preterm delivery in women with cervical length＜10 mm was significantly higher than that in women with cervical length ≥ 10 mm (P<0.01).Conclusions The detection of length and shape of the cervix by perineal ultrasonography is an objective and effective method for predicting preterm birth.The shortened cervical length and the broadened cervical width are high risk indexes of premature delivery.The method is sensitive,which can be an important index for predicting premature labor. |
