Introduction: Prolonged pregnancy, also known as post-dated pregnancy, is a pregnancy that has lasted longer than the 40 completed weeks of gestation or 280 days from the beginning day of the last menstrual period (LMP). Foetal, neonatal, and maternal complications have been linked to post-term pregnancy. Aim: To find out the mode of delivery, maternal complications, and neonatal outcome in a pregnancy lasting beyond 40 weeks of gestation. Materials and Methods: This is a prospective observational study conducted in a tertiary care centre with a sample size of 146 cases, with pregnancies lasting beyond 40 completed weeks of gestation. Results: In this study 50% of the patients were aged between 18-25 years. Majority, 57%, of patients were primigravida. 87% of study population was between 40-41 weeks of gestation, while 13% were above 41 weeks. Lower segment caesarean section (LSCS) was the mode of delivery in 60% of the patients, with foetal distress being the most common indication for LSCS and was noted in 25% of patients. In this study 25% of patients encountered obstetrical complications and 45% of the neonates born were admitted to the neonatal intensive care unit. Conclusion: The percentage of pregnancies deemed "post-term" can be significantly decreased by a dating policy that ignores menstrual dates and establishes the expected date of delivery solely based on ultrasound dates. Early intervention in post-dated pregnancy should be implemented to prevent maternal and perinatal problems.
