Background: Caesarean section is the most common done obstetric emergency and the outcome of surgery differs depending on various factors. Maternal and fetal outcome depends on proper follow up during antenatal period. Aims: To study the maternal and fetal outcome of emergency caesarean delivery between unbooked rural referrals and booked cases. Materials and methods: This is a Comparative cross sectional study was conducted in the Department of Obstetrics and Gynaecology in Gestational age > 37 weeks, Unbooked cases handled outside and referred, who underwent caesarean delivery on emergency, Booked cases admitted in our hospital and underwent emergency caesarean delivery and Singleton pregnancy. Results: This study included 980 antenatal patients who underwent emergency caesarean section, among them 420 were booked cases and 560 were unbooked cases. The incidence of emergency caesarean section was more in unbooked group compared to booked group. This comparison of age, Teenage pregnancy, parity, socioeconomic status had statistical significance with p value < 0.05. The major indication of emergency caesarean section in booked cases was previous caesarean section (29.26%), where as it was fetal distress (22.6%) in unbooked group. Septicaemia in unbooked group (4.6%) was more than booked group(1%).66 cases (11.8%) of unbooked group and only 21 cases (4.9%) of booked group had wound infection. Postpartum haemorrhage, Perinatal mortality, NICU admission rate statistically significant among the two groups. Maternal intrinsic factors such as nutrition socioeconomic status and lack of antenatal care have been suggested as the causative factors in the unbooked patients. Conclusion: Poor utilization of antenatal care is associated with adverse feto-maternal outcome. Most maternal deaths are preventable if complications are diagnosed early and managed effectively in time .Early admission and management of critical obstetric patients decreases maternal morbidity and mortality
