Background: Admission cardiotocography (CTG) comprises recording of foetal heart rate and uterine contractions for 20 minutes done at the time of admission to labour room. This test can identify foetuses who are compromised during early labour and are in need for continuous foetal monitoring. Aim: To evaluate the role of admission cardiotocography in predicting the pregnancy outcome in post-dated pregnancies. Methodology: This study was a hospital based cross-sectional study conducted in the department of obstetrics and gynaecology, Jorhat Medical College and Hospital from July 2021 to June 2022. Admission cardiotocography was done in 90 post-dated pregnant women with singleton pregnancies admitted in labour room. Results: The admission CTG was normal in 70 % of all patients, suspicious in 10% and pathological in 20 %. The neonatal outcomes in term of foetal distress, meconium stained liquor and NICU admissions were considerably higher in patients with pathological result. The sensitivity of test was 81.4% and specificity was 92%.Conclusion: Admission CTG is a simple, useful screening test and serves as a non-invasive tool in forecasting the adverse foetal outcomes in high risk pregnancies.
