Abstract
The presence of cervical wedging may predict shorter labors among women being induced. Fifty-three women, all but two beyond 38 weeks' gestation, underwent transvaginal ultrasonography and digital cervical exam before induction. Labor length did not correlate with cervical effacement or dilation values obtained by digital exam. The presence of a cervical wedge, an indentation of the cervix on the fetal side, was associated with a shorter median duration of latent phase labor (15.9 hr vs 34.1 hr) and shorter median duration of total labor length (22.0 hr vs. 38.3 hr). Cervical wedging is visible with transvaginal ultrasonography but is not perceivable during a digital exam. It appears to be a component of cervical ripening. The presence or absence of wedging may prove useful in evaluating the inducibility of candidates for labor induction.
