This was a hospital based prospective randomized observational study over a period of 1 year. To see the correlation between suspicious/pathological CTG and umbilical cord blood pH at birth in term pregnancies. An undisputed evidence of perinatal asphyxia is metabolic acidosis on arterial cord blood or very early neonatal samples: pH12 mmol/L Despite its popularity, it has not been proved to be an ideal tool for monitoring as, although a normal trace is indicative of a normal acid-base status at birth, in about 98% of cases, an abnormal trace has a low positive predictive value in term of fetal acidosis (pH less than 7.25). Fetal Cardiotocography (CTG) has been used for long to predict fetal asphyxia. Perinatal asphyxia is one of the major causes of neonatal morbidity and mortality.
