Abstract: Objective: To compare caesarean section rate and perinatal outcome among women with postdate pregnancies having one previous scar induced at 40+10 weeks and 40 weeks Study Design: Quasi-experimental study. Place and Duration of Study Obstetrics department, Pak Emirates Military Hospital Rawalpindi, Pakistan from Jan to Jun 2022 Methodology: The study was conducted on women with one previous scar who were booked cases in our department and did not have spontaneous vaginal delivery till 40 weeks of gestation. They were divided into two groups. One group had an induction of labor at 40 weeks, while the other had an induction at 40+10 weeks. Clinical parameters like rate of Caesarean section for delivery, meconium aspiration, hypoxic-ischemic encephalopathy, and meconium-stained liquor were compared in both groups. Results A total of 413 women with one previous scar and post-dated pregnancies were recruited for this study. Two groups were made for comparison. 182(44.1%) mothers had induction at 40 weeks, while 231(55.9%) had induction at 40+10 weeks. 208(50.3%) had a vaginal birth after the caesarean section, while 205(49.7%) underwent a Caesarean section. Statistical analysis revealed that more caesarean rate, meconium aspiration, hypoxic-ischemic encephalopathy, and meconium-stained liquor were found in the 40+10 weeks group (p-value<0.05). Conclusion Induction at 40 weeks turned out to be a better option in women with postdate pregnancies when compared to induction at 40+10 weeks in terms of rate of Caesarean section, meconium aspiration, meconium stained liquor, and hypoxic-ischemic encephalopathy.
