摘要：To determine the diagnostic accuracy of Cardiotocography in determination of good and poor Apgar score after delivery of fetus at term. Methods: This was a cross sectional study done at Obstetrics & Gynecology department, Lady Atchison hospital, Lahore for 6 months, after ethical approval of study. 448 cases were included through nonprobability consecutive sampling method. Initial CTG monitoring was done and normal and abnormal CTG was labeled. After delivery of baby, assessment for Apgar score was done. The good and poor Apgar score was labeled and the findings were co-related with the CTG findings. A proforma was specifically designed to record findings of this study. Data was analyzed by using SPSS 16. The sensitivity, specificity, Positive & Negative Predictive Values and diagnostic accuracy of abnormal CTG were calculated by taking Apgar score at birth as gold standard. Results: The mean age of the patients was 30.42±5.73 years. The mean gestational age was 38.20±1.10 weeks. The mean Apgar score after 5 minutes of birth was 6.67±1.67. There were 183 (40.8%) females who had abnormal CTG while 265 (59.2%) females had normal CTG. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of CTG at birth were 65.9%, 51.4%, 67.9%, 49.2% and 60.3% respectively. Conclusion: CTG is a good screening tool to assess mother & fetus wellbeing but it is not a diagnostic tool for fetal surveillance in females undergoing delivery at term.
