Introduction: The obstetrician has to play pivotal role. In life, time plays an important role and nobody is blessed with immortality and so does the fetus. The problem of postdatism is subject of concern to couple and the obstetrician.With this objective present study was planned to study of perinatal morbidity and mortality in postdated cases in tertiary care hospital.Material and methods: A prospective study of 80 cases of uncomplicated prolonged pregnancies was done during the period of one year at teaching hospital in our hospital. Study was approved by Institutional Ethics Committee. Sample size estimation was done by expert. Age , Gravidity and parity Gestational age LMP (Last Menstrual Period) Early ultrasound Other associated risk factors Antepartum feotal surveillance.Induction was preceeded with reactive NST Written valid informed consent taken. Depending on Bishops score and NST after 6 hrs.ofcerviprimePGEa gel instillation either augmentation with oxylocin was considered.In labour, patients were clinically monitored for progress of labourfoetal distress &colour of liquour.Results : Thus it is evident that incidence of meconeum stained amniotic fluid has increased from 21.6% in 40-41 weeks to 100% in 42 weeks i.e. with advancing gestational age. However MAS was seen only in 4 patients. In a study conducted by Shime et al meconeum was 28% in prolonged pregnancy and 17.71% in control pregnancies which is not statistically significant. Also to study conducted by NICHHD meconeum was detected with equal frequency in all age groups. None of the patients with thin or absent meconeum develop meconeum aspiration. Meconeum stained liquor Meconeum aspiration syndrome Apgar score < 7/10 Birth Asphyxia Postmaturity Syndrome Congenital Anomalies Perinatal Mortality.Conclusion: In conclusion, thus management of postdated pregnancy should be tailored for an individual case and depends on the obstetrician and facilities available. There should be harmonious blend of skill and judgement to give healthy baby to a healthy mother.
