摘要
经会阴Ｂ超，对１００例孕３８～４２周的孕妇进行子宫颈成熟度评分。其中８６例为正常妊娠，１４例有产科合并症及并发症。胎位均为头位。阴道分娩５９例，剖宫产４１例（其中１１例未临产）。通过观察宫颈长度、官颈内口扩张程度、先露高度、宫颈回声强度和宫颈位置，参照宫颈Ｂｉｓｈｏｐ评分，建立超声宫颈成熟度评分标准。结果：评分≥９分者１４例，临产所需时间３．９±３．１小时，均临产；５～８分者５４例，临产所需时间为２０．８±３．９小时，均临产；≤４分者３２例，临产所需时间为４６．９±３．９小时，２１例临产；三者间比较，临产时间差异有极显著性（Ｐ＜０．００１）。当羊膜囊突入宫颈管内时，临产所需时间为５．３±３．７小时。提示：经会阴Ｂ超行子宫颈成熟度评分是一种简单可行的评分方法。
bjective To evaluate cervical ripening in pregnancy at term by trans-perineum ultrasound. Methods The cervical length,cervical internal os width,cervical echo intensity,cervical position and distance between fetal presentation and vaginal external os were assessed by trans-perineum ultra-sound(transducer 3. 5MHz)in 100 cases of normal pregnant women at term。Results On the basis of Bishop score,the results showed,cervical ripening score≥9,14 cases were in labor, mean parturient time 3.9±3.1 hours;5～8scores,54 cases were in labor, mean parturi-ent time 20.8±3. 9 hours;≤4 scores,32 cases in which only 21 cases were in labor,mean Darturient ime 46. 9± 3.9 hours,The results were significantly different among the three groups.Concl usions Ultrasonographic cervical ripening score is an objective noninvasive method for as-sessment of cervical ripening at term.
