A group of 8303 women was studied to determine the timing of cervical ripening. It was confirmed that these signs of cervical change can be observed several weeks before preterm births. The precocious signs of external ripening can be recognized during a vaginal examination and may be useful in predicting preterm labor.
对8303名女性进行了研究,以确定宫颈成熟的时间。已证实,在早产前几周就能观察到这些宫颈变化的迹象。外部成熟的早熟迹象可在阴道检查时识别出来,可能有助于预测早产。
