Association of Cervical Effacement With the Rate of Cervical Change in Labor Among Nulliparous Women.

ABSTRACT:

Objective

To assess the association of cervical effacement with the rate of intrapartum cervical change among nulliparous women.

Methods

We conducted a secondary analysis of a prospective trial of intrapartum fetal pulse oximetry. For women who had vaginal deliveries, interval-censored regression was used to estimate the time to dilate at 1-cm intervals. For each given centimeter of progressive cervical dilation, women were divided into those who had achieved 100% cervical effacement and those who had not. The analysis was performed separately for women in spontaneous labor and those who were given oxytocin.

Results

A total of 3,902 women were included in this analysis, 1,466 (38%) who underwent labor induction, 1,948 (50%) who underwent labor augmentation (combined f
