Background: Pregnancy duration, extends to or beyond 40 weeks or 280 days from the first day of the last menstrual cycle is regarded as postdate gestation. This condition poses potential risks to both mother and the fetus including at increased chances of stillbirth, macrosomia, meconium aspiration syndrome and labour complications. Aims and Objectives: To study maternal outcome, rate of vaginal and caesarean section, perinatal outcome in pregnancy beyond 40 weeks of gestation. Materials and Methodology: This prospective study was conducted at a tertiary care Municipal hospital in East Ahmedabad in obstetrics and gynaecology department from November 1, 2022 to April 30, 2024. There were an average of 2526 deliveries, 150 cases of postdatism (5.93%) were included in the study. Results: In present study majority of the cases (68.66%) belonged to the gestational age 40weeks to 40weeks + 6days. Total 32% cases had amniotic fluid index <5 cm. The caesarean section rate in present study was 46% with most common indication for caesarean section was meconium-stained liquor (24.63%), second most common indication for caesarean section was cephalopelvic disproportion (20.28%). Out of 150 babies, 33(22.00%) cases need NICU admission after delivery. The most common cause of neonatal complication was meconium aspiration syndrome (13.33%) followed by respiratory distress syndrome (4.66%). 3(2%) cases had intrauterine foetal death. Conclusion: Maternal risks associated with postdated pregnancy include prolonged labor, increased likelihood of instrumental delivery or cesarean section, and higher rates of postpartum hemorrhage. Fetal risks include a higher likelihood of meconium aspiration syndrome, macrosomia, and dysmaturity syndrome and NICU admission. Vigilant monitoring and timely intervention are crucial to reduce potential risks for the mother and the fetus.
