Aim: To compare the maternal and fetal outcome between term and post dated pregnancies.
Methodology: Keeping in mind that the post dated pregnancy causes lot of threats to the mother and the fetus, in our hospital, labor is induced at 40 completed weeks i.e. at 40+0 weeks. In this study we tried to find out the prevalence of Post dated pregnancy (pregnancies beyond 40 weeks), it’s maternal and fetal outcome and compare the same with term pregnancy (37-40 weeks).
Results: In the present study, total of 2174 cases were studied out of which 486 cases were post dated pregnancies. The incidence of post dated pregnancy was 17.36%. PRIMIs were more prone for post dated pregnancies according to our study. The ‘P’ value was statistically significant (p<0.001) in the following outcomes- Intra uterine fetal deaths, forceps and vaccum assisted vaginal deliveries, emergency LSCS, meconium stained liquor causing fetal distress, lower APGAR scores, admission to NICU ,all were more in post dated pregnancies compared to term pregnancies with statistic significance proving the same.
Conclusion: Maternal morbidity increased in the form of emergency LSCS, postpartum hemorrhage, instrumental deliveries, as the gestational age increased beyond 40 weeks. The study also showed that there was significant increase in perinatal morbidity and perinatal mortality in the form of birth asphyxia, meconium aspiration syndrome and perinatal death as the gestational age went beyond 40 weeks. Maternal and fetal morbidity and mortality can be reduced by electively inducing pregnant women at 40+0 weeks as allowing them to continue beyond this gestational age has shown adverse feto-maternal outcomes.
