COMPARATIVE STUDY OF NORMAL AND ABNORMAL CTG IN TERM PREGNANT WOMEN IN LABOUR AND ITS PERINATAL OUTCOMES

Author(s): K. Aruna Kumari BACKGROUND EFM was introduced into Obstetric practice during late 1960 on the premise that it would facilitate early detection of abnormal foetal heart patterns thought to be associated with hypoxia thus allowing early intervention to prevent foetal neurological damage or death.1 In this study, we aim to evaluate the effect of CTG on perinatal outcome in low risk and high-risk population and determine the cost-effective reliable method of foetal monitoring that is applicable to low risk and high-risk population.2 MATERIALS AND METHODS A prospective randomized study conducted on 200 pregnant women in labour who were admitted to labour room in the department of OBGY, Niloufer Hospital. The Duration of study is one year. These women were divided into two groups, group-A & group-B. RESULTS The demographic features parity and gestational age in both the groups were comparable. The mean age group of the patient is 23 years and mean gestational age is 37.77 weeks. In this study, 125 (62.5%) belong to high risk group and 75(37.5%) belong to low risk group. In the present study normal CTG was seen in 59.5%, suspicious CTG in 11% and pathological CTG in 29.5% in low risk group and in high risk group normal CTG was seen in 51.2%, suspicious CTG in 9.6% and pathological CTG in 39.2%. Incidence of MSL was more in women with abnormal CTG finding in both low and high risk women.3 NICU admissions were 55.9% in patient with abnormal CTG as compare to 1.7% in normal CTG patterns.4 The sensitivity, specificity, PPV and NPV of CTG in Prediction of low APGAR score at 5 minutes was 93.75%, 80.13%, 50.84% and 98.31% respectively. CONCULSION Continuous CTG monitoring identifies conditions causing foetal compromise at an early stage of labour so that timely intervention can be taken.5 Present study had shown that the abnormal CTG finding were associated with significantly increased incidence of LSCS, low mean APGAR scores, increased NICU admissions.
