Abstract

CTG test is a non-invasive investigative modality that is simple to perform and interpret, as well as widely accepted by patients. This test involves the use of Doppler-detected fetal heart rate acceleration that corresponds to fetal movements perceived by the mother. Owing to its cost-effectiveness and ease of application, it is used as a part of antenatal surveillance in developing countries. To analyze and monitor CTG changes in high and low-risk pregnancies as a part of antepartum surveillance and to correlate CTG with perinatal outcomes. Methods: A prospective observational study was conducted in the department of obstetrics, government medical college, Guntur. 200 pregnant females were enrolled in this study after they full filled the selection criteria. Patients were subjected to admission CTG and fetal heart rate was monitored. Perinatal outcomes were assessed. Results: 63% of the 200 patients had high-risk pregnancies. 61.5% needed operative delivery while 38.5% of the cases had NVD. APGAR score at 1 minute was <6 In 40%, & >7 in 60% of the cases. APGAR score at 5 minutes was <7 In 20% and 80% of the cases it was >8. Beat-to-beat variability was absent in 44% of the cases. There was a statistically significant association between perinatal outcome and beat-to-beat FHR variability. A significant association was observed between diagnosis and CST. Conclusion: Admission CTG is an effective, inexpensive, non-invasive technique to detect fetal hypoxia at early stages in low-and high-risk pregnancies, especially in developing countries with an increased workload and fewer resources.
