“…Similar results were also reported by Yang et al [19] . However, in three subsequent studies digital cervical examination and not cervical ultrasonographic assessment was the best predictor of successful labor induction [20][21][22] . We did not examine cervical wedging, as we believe that this is closely related to a short cervix.…”

Objective: The purpose of the study was to determine if transvaginal sonographic measurement of the cervical length is a useful method to predict successful labor induction in nulliparas. Methods: 137 women who were scheduled for medically indicated induction of labor had a transvaginal sonographic measurement of the cervical length before labor induction. Inclusion criteria were: (1) singleton pregnancy; (2) gestational age between 37–42 weeks; (3) live fetus in cephalic presentation; (4) intact membranes; (5) no vaginal bleeding; (6) no previous history of uterine surgery; (7) nulliparous women, and (8) no allergy or asthma in response to prostaglandins. Induction of labor was performed within 6 h of the ultrasonographic examination, by inserting 2 mg of dinoprostone in the posterior vaginal fornix, repeated if needed every 6 h for up to three doses. When the cervix became favorable and no regular contractions were observed, amniotomy and oxytocin augmentation, starting at 1 mIU/min and increasing 1 mIU every 30 min as necessary, was performed. Results: All women were Caucasians and the mean age was 24.3 years (range 19–37 years). The mean cervical length was 28 mm (range 11–39 mm). The Bishop score was ≤5 in 101 women and >5 in the 36 others. Vaginal delivery occurred in 92 women (67.1%), and the vast majority of them (89 women; 96.7%) gave birth within 24 h of induction. Forty-five women (32.8%) had a cesarean section. The Bishop score was not predictive of the mode of delivery. Thirty-six of 101 women (35.6%) with a Bishop score ≤5 delivered by cesarean section, compared to 9 of 36 women with a Bishop score >5 (25%) (p = NS). Women with a cervical length <27 mm were more likely to deliver vaginally. Using this cutoff value the sensitivity of a successful labor induction was 76% and the specificity was 75.5%. Conclusions: Transvaginal sonographic measurement of cervical length is a good predictor of a successful labor induction at term in nulliparas.

“…In addition, if the standard deviation of one group is much higher than that of another while the means of both are similar, arbitrarily set cutoffs might reduce this bias. Similarly, Roman et al [21] found that the length of the latent phase and that of total labor were signifi cantly shorter in parous compared with nulliparous women undergoing induction of labor. However, these fi ndings are also in contrast with our results showing that parity was not signifi cantly associated with an increased risk of failed induction.…”

Background: Our purposes were to determine the effect of preeclampsia, magnesium sulfate prophylaxis, and maternal weight on labor induction in women with preeclampsia and identify risk factors associated with its failure. Methods: Fifty-five preeclamptic women and 176 non-preeclamptic women requiring labor induction over an 18-month period were studied retrospectively. Prostaglandin E₂ (dinoprostone) and oxytocin were used for labor induction. Women with rupture of the membranes, spontaneous contraction resulting in cervical change, or an initial cervical examination showing more than 2 cm dilatation and 50% effacement were excluded. Statistics were analyzed with χ² test, Fisher’s exact test, Student t test, Mann-Whitney U test, and multiple logistic regression. Results: The women with preeclampsia had a significantly higher rate of failed induction than did those without preeclampsia (p = 0.01). However, the women with preeclampsia had a higher mean maternal weight and an increased use of magnesium sulfate, and labor was induced at earlier gestational age than in those without preeclampsia (p < 0.05 for each). Multiple logistic regression showed that the use of magnesium sulfate, higher maternal weight, and unfavorable cervix, but not preeclampsia, were significantly associated with an increased risk of failed induction after correction for known confounding variables. Conclusions: Although the risk of failed induction is increased in preeclamptic women, preeclampsia is not an independent risk factor for failed induction. The use of magnesium sulfate, higher maternal weight, and unfavorable cervix are independent risk factors for failed induction.

“…Cette association n'a cependant pas été démontrée dans d'autres études [30][31][32][33][34][35][36]. Rozenberg et al [36] remarquent, dans leur article, les nombreux biais des études retrouvant une association entre la longueur cervicale échographique et la durée du travail induit.…”
