The Correlation between Intra-Partum Cardiotocography (CTG) and Umbilical Cord Arterial pH in Predicting Perinatal Outcome

Dr. Sonika Sharma | Dr. Jyotsana Lamba

Abstract: Introduction: Monitoring of fetus intrapartum is an important step for prediction of fetal distress and impending worst situations. Aim of this study is to find the correlation between the most common used techniques i.e. CTG and the less common used technique i. e umbilical cord pH to predict fetal distress and further improve its accuracy. Methods: 250 women were enrolled with singleton pregnancies. CTG were classified according to NICHD 2008 guidelines. Immediate umbilical cord artery blood was sent to laboratory for testing of pH. Various analyzing factors were used to find correlation among above two. Result: Enrolled cases were from age group 21-30 years (82.80%), having gestational age of 37-40 weeks (79.2%). CTG category I were in 51.6% of subjects, followed by category II in 34.8% of subjects, lastly category III in 13.6% of subjects. CTG Category I only 11 (8.53%) were having acidosis; category II were 21 (24.14%) patients lastly with category III 18 (52.94%). Conclusion: from this study, a very important conclusion is that, intrapartum cardiotocography has good correlation with umbilical cord arterial pH for predicting neonatal outcome and can be used for screening fetuses in distress and to save the most venerable fetal hypoxia by early warning signs given by this technique.
