Introduction: Electronic fetal heart rate monitoring (EFM) involves the use of a cardiotocography (CTG) to record the fetal heart rate (FHR) so as to determine the fetal well-being in order to detect signs of intrapartum hypoxia. Objectives: The objective of this study is to find relationship between abnormal cardiotocography and cord blood pH at birth in term pregnancies. Material and methods: This Observational study was conducted at Services hospital Lahore during 2019. From all females or attendants, their contact information, demographic, gestational history was taken. Immediately after the delivery of the baby, about 10 cm of umbilical cord was doubly clamped. Two milliliters of arterial cord blood was taken in a pre-heparinized syringe and sent to laboratory within 10 minutes for assessment of fetal pH. According to operational definition pH levels < 7 was noted. All data was collected on performa by researcher herself. Results: The data was collected from 323 patients. The mean gestational age was 39.27±5.65 weeks. The mean birth weight of new born was 3189±203.48 grams. The most common perinatal risk factors accompanied with low umbilical artery pH were prolonged rupture0 of membranes, breech presentation, and meconium stained amniotic fluid. According to data, there was no significant correlation between cardiography and 5th minute umbilical cord pH in term pregnancies. Conclusion: It is concluded that cardiotocography (CTG) had become a popular method for monitor fetal wellbeing and it is assisting the obstetrician in making decision on the mode of delivery to improve perinatal outcome. But there is no significant relationship between CTG and cord blood pH.
