Back ground: Labour is a very short period in the life of a foetus but poses maximum threat. Improvements in medical technology have made it possible to monitor fetal well-being during labour. Premature rupture of membranes (PROM) refers to a patient who is beyond 37 weeks gestation and has presented with rupture of membranes (ROM) prior to the onset of labour.(1) It is an important cause of maternal and fetal morbidity and increased rate of caesarean delivery. The aim of the study is to evaluate the admission cardiotocography in prelabour rupture of membranes and correlate with mode of delivery. Methods: This prospective study was done on 200 patients above 37 weeks of gestation in cephalic presentation. All women were subjected to an admission cardiotocography, which included a 20 minute recording of fetal heart rate and uterine contraction. Results: Out of 200 patients the majority of women were primi gravida belonging to the age group of 18-24 years. The mean age group is 24.7 year. The admission CTG were ‘reactive’ in 132 cases, ‘suspicious’ in 48 cases, and ‘omnious’ in 20 women. Conclusion: The admission CTG is simple, convenient, non invasive and economical for screening purpose. PROM is important cause of maternal morbidity and increased rate of caesarean delivery.
