Assessment of maternal and perinatal outcome in postdated pregnancies in a tertiary care center

Objectives:1)To assess the maternal and perinatal mortality and morbidity in uncomplicated postdated pregnancies in a tertiary care centre. 2) To find out the causes and rates of different modes of delivery in uncomplicated postdated pregnancies in a tertiary care centre. Methodology: A prospective observational study was done in the O&G department of JMCH, Jorhat, Assam from June 2020 to May 2021 among 110 uncomplicated postdated antenatal patients including both primigravida and multigravida willing to participate in the study and meeting both inclusion and exclusion criteria, attending the OPD and admitted at labour wards and their new born upto 7 days and maternal and perinatal mortality and morbidity was studied. Data was collected using a proforma after taking informed consent. Data pertaining to mode of delivery, type of vaginal delivery, indications of caesarean section, maternal complications, birth weight, APGAR score at 1min and 5min, perinatal morbidity and perinatal mortality were analysed. Results: Majority of women belonged to age group 20 to 25 years (51.8%). 60% of them delivered vaginally,7.2% had instrumental delivery whereas 32.8% women required caesarean section, the most common indication being meconium stained liquor (25%). 49.1% of women were given induction by various means and 45.5% of them had successful vaginal delivery.12.7% babies had NICU admission with respiratory distress (28.6%) being the most common reason. Conclusion: Postdated pregnancies can be considered as a high risk pregnancy due to higher maternal and fetal complications. With regular antenatal check up, the incidence of post dated pregnancies can be decreased.
