Objective: To quantify the frequency of serious maternal complications associated with cerclage use during pregnancy. Study design: We performed a retrospective population-based cohort study of all live births in Ohio from 2006 to 2015. Maternal sociodemographic, medical, and obstetric characteristics were compared for births in which cerclage was utilized during the pregnancy versus those without cerclage. The primary outcome for the study was a composite of adverse outcome including maternal intensive care unit (ICU) admission, blood product transfusion, uterine rupture and unplanned hysterectomy in all births. Secondary outcomes included each of the individual adverse outcomes as well as maternal hospital transfer to a tertiary facility, unplanned operation after delivery and chorioamnionitis. Each outcome was also analyzed separately in singleton and twin births. Generalized linear modeling was used to estimate the relative risk of adverse maternal outcomes associated with cerclage placement after adjustment for coexisting risk factors. Results: Of the 1,428,655 singleton and twin live births in Ohio from 2006 to 2015, 4595 [0.3%] were recorded on the birth certificate as having cerclage during pregnancy. Of those, 11.7% experienced a serious adverse maternal outcome, compared to 3.7% without cerclage, adjRR 2.7 [95% CI 2.5, 3.0]. The rate of the composite maternal adverse outcome was significantly increased for pregnancies with cerclage versus those without overall, and in singleton and twin pregnancies when measured individually [all p ≤ .001]. Even after adjustment for coexisting risk factors, cerclage remained significantly associated with composite adverse outcome in each of these groups. Conclusions: Over 1 in 10 women with cerclage experience an adverse maternal outcome. Even after adjusting for gestational age at delivery and other risk factors, maternal risk for serious adverse event remains over twofold increased for pregnancies with cerclage. This information may be helpful in counseling women regarding potential maternal risk when considering neonatal benefit of cerclage in pregnancies at high risk of preterm birth.

Objective: The objective of this study is to determine whether cervical ripening with misoprostol (MP) is associated with higher rates of cesarean delivery (CD) compared with dinoprostone (DP) or Pitocin/Foley balloon (PFB) in infants found to be small for gestational age (SGA). Study design: Single center institution based cohort study of all inductions between 2008 and 2012 where birth weight was found to be as SGA (< 10th percentile). Maternal demographic, obstetric, and labor characteristics were compared between SGA births where cervical ripening with MP, DP, or PFB was used as the primary agent. The primary outcome was CD after attempted induction between the three study groups which included MP, DP, and PFB. Secondary outcomes included inability to achieve active labor (defined as cervical dilation of 6 cm or greater), cervical dilation at the time of CD, the incidence of CD for the indication of non-reassuring fetal status, and neonatal outcomes including Apgar scores and admission to neonatal intensive care unit. Multivariable logistic regression was performed to evaluate the association of these outcomes with MP as the induction agent versus the referent groups, PFB. Results: Of 260 inductions where the infant was found to be SGA by birth weight during the 5-year period, 172 (66.2%) patients were induced using MP, 38 (14.6%) with DP, and 50 (19.2%) with PFB. There were no differences in baseline characteristics between groups (age, race, BMI, parity, induction indication, birth weights, or maternal comorbidities). MP did not increase rate of CD which was 25.6%, 26.3%, and 22.0% in the MP, DP, and PFB groups, respectively (p = .86). There were also no differences in incidence of CD for non-reassuring fetal well-being (NRFWB), failure to attain active labor, or cervical dilation at time of CD between induction groups. NICU admission was 18%, 18%, and 16% (p = .94) between MP, DP, and PFB groups, respectively. MP was not associated with an increased rate of CD when compared with the other two agents combined, aOR 0.93 (0.67-1.30, 95% CI). Conclusion: MP appears to have similar efficacy and safety when compared with other cervical ripening agents in pregnancies complicated by SGA. [ABSTRACT FROM AUTHOR]
