Abstract
Objective: To determine the predictability of intrapartum cardiotocography with meconium staining of liquor and the subsequent requirement for newborn admissions. Methods: This cross sectional study was conducted at obstetrics and gynaecology department, KAP Viswanatham Medical College, Tiruchirapalli from September 2018 to February 2019 and consisted of women in labor taken up for primary caesarean section with various indications. Their cardiotocographic findings were analysed and was correlated with colour of liquor and the need for newborn admissions. Intrapartum cardiotocography was performed and the findings were recorded. The colour of liquor was observed. Cardiotocography was performed for 20 minutes in left lateral position during labor. Inclusion Criteria: 1) Primary caesarean section patients. 2) Gestational age greater than 37 weeks. Exclusion criteria: 1) Preterm, intrauterine death and congenital anomalies. 2) Antepartum haemorrhage. 3) Cord prolapse. Results: Among the total 212 patients, 117 (55%) CTGs were reactive and 95 (45%) CTGs were non reactive and abnormal. The most common indication for primary caesarean section during this period was fetal distress 93 (43.8%). Out of the 117 reactive CTGs, 108 (50.9%) had clear liquor and 9 (4.2%) had meconium stained liquor. Of the 95 non reactive CTGs, 53 (25%) had clear liquor and 42 (19.9%) had meconium stained liquor. Of the 117 normal CTGs, 17 (8.1%) babies required newborn admissions. Of the 95 abnormal CTG, 55 (25.9%) babies required newborn admissions. Of the high risk patients, premature rupture of membranes (PROM) patients had the highest percentage of pathological CTGs. Among the patterns of pathological CTG, late decelerations 28 (29.4%) were the commonest finding. Conclusion: Cardiotocography is an important tool for monitoring of fetal well being during pregnancy and labor. Pathological CTG implicates higher probability of perinatal asphyxia. Unfortunately, CTG also has large number of false positive findings. Significant CTG changes were seen in clear liquor patients also. Hence additional evaluation for ongoing hypoxia like ultrasound, Doppler examination and pH monitoring should be cautiously used. Both abnormal CTG and meconium stained liquor are a definitive sign of fetal distress but not in all patients.
