Abstract
Aim: The aim of this study is to evaluate the association of placental localization and outcome of induction of labor in uncomplicated postdated pregnancy.
Methods: It was prospective observational study done over a period of one month. The women with uncomplicated postdated singleton pregnancy who failed to enter spontaneous labor and were willing to participate in the study and who met the inclusion and exclusion criteria were enrolled. A total of 70 women were recruited and underwent clinical and ultrasound examination. Eligible enrolled women were induced by an intravaginal prostaglandin according to hospital protocol. According to the type of response to induction, women were divided into two group responder and non responder group.
Results: Among 70 enrolled participants 47% (n=33) women had anteriorly located placenta, 47.1% (n=32) women had posteriorly located placenta and 7.1% (n=5) had fundal placenta. Women with advanced maternal age (p<0.032) and urban resident females (p<0.001) had higher rate of failed induction of labor. Women with anteriorly located placenta showed a higher incidence of failed induction of labor (p< 0.001) in postdated uncomplicated singleton pregnancies and had higher rate of cesarean section.
Conclusion: An ultrasound based predictive model has been framed through this study based on the fact that anteriorly placed placenta has a significant association with failed induction of labor and thus help to identify postdated pregnant females who might have poor outcome of labor induction.
