Abstract

Introduction: Post-term pregnancy is defined as pregnancy reaching to or extending beyond 42 weeks of gestation from the last menstrual period. The introduction of routine ultrasound for gestational age dating has significantly reduced the incidence of post-term pregnancy. An increased risk of perinatal mortality and morbidity also found in the post-term babies. Maternal factors also plays a major role in delivery for ≥42 completed gestational weeks.

Materials and Methods: This study is a prospective cohort study conducted on 110 live births born between April 2019 and March 2020 in a tertiary care hospital.  Data were collected using a structured questionnaire and twice daily examination of the baby. The complication developed is recorded and detailed maternal history also taken.

Results: The prevalence of post-term births to be 3.9%. Advanced maternal age, oligohydramnios and previous history of post term delivery were found to be the major factor responsible for the post-term delivery. Meconium staining of amniotic fluid, Meconium aspiration syndrome, birth asphyxia, polycythemia, hypocalcemia and hypoglycemia are found to have higher incidence in post-term babies. Neonatal mortality in post-term neonates in our study was 10.1%.

Conclusion: Primiparity, advanced maternal age and previous post-term delivery were found to be the strongest risk factors for post-term pregnancy. Study also demonstrated an association between post-term pregnancy and an increased risk of adverse neonatal outcome for post-term babies. This should be kept in mind by obstetricians when considering the management of post-term pregnancy as well as by paediatricians who need to be aware of the higher rate of complications in post-term neonates.
