Analysis of Risk Factors for Cesarean Section after Induction of Late-term Pregnancy / 中国医科大学学报

ABSTRACT

Objective To explore the risk factors for cesarean section after induction of late-term pregnancy. Methods This study enrolled 275 primiparas with a single cephalic fetal presentation,admitted to our hospital between December 2010 and December 2016 for induction of late-term pregnancy. After induction,80 underwent cesarean section and 195 had a normal vaginal delivery. Clinical data were collected and analyzed retrospectively. Single factor analysis and two categories of logistic regression analysis were used to determine the independent risk factors for cesarean section after induction of late-term pregnancy. Results Single factor analysis showed that the differences between the two groups in maternal height,cervical Bishop score before induction of labor,latent phase,intrapartum amniotomy,intrapartum oxytocin,meconium stained amniotic fluid,and birth weight were statistically significant (P < 0. 05). Multivariate analysis showed that maternal height,cervical Bishop score before induction of labor,and latent phase were independent risk factors for cesarean section after induction of late-term pregnancy. Conclusion Late-term pregnant primiparas with short stature,low Bishop score,or a long latent phase should have comprehensive prenatal maternal-fetal assessment,and a reasonable delivery mode should be chosen to avoid adverse outcomes.
