Background: Objective of the study was to find out the incidence of maternal complications, perinatal mortality and morbidity in postdated pregnancies. Design of the study was prospective observational study.Methods: Patients who have completed 40 weeks of gestational age, patients who were sure of the date of last menstrual period (LMP) along with 1st trimester obstetrics scan were included. Patients not sure of LMP were excluded.Results: There is high fetal and maternal risk associated with postdated pregnancy. Total 100 cases were selected from antenatal clinic and Labour Room and were divided into two groups. Study group and control group, 50 cases in each. Induction rate is more in postdated pregnancies. Incidence of operative deliveries is 54% in study group. Postpartum haemorrhage and septicaemia are the most common maternal complication in the study group. Perinatal mortality is higher and more NICU admissions were required.Conclusions: Considering this, policy of early intervention should be undertaken in postdated pregnancy to avoid maternal and perinatal complications
