Admission Cardiotocography Screening of High Risk Obstetric Patients.

BACKGROUND: To predict the neonatal outcome in high risk obstetric cases by admission cardiotocography (CTG) testing. METHODS: A total of 150 consecutive high risk obstetric patients meeting the inclusion criteria were subjected to admission CTG testing in this prospective study. The CTG tracing was categorized based on Royal College of Obstetricians and Gynaecologists (RCOG) criteria. Specific foetal and neonatal outcome measures were studied and correlated with the admission CTG testing. RESULT: Foetal distress during labour developed in 15% of patients with a normal test and in 73% of patients with an abnormal test. The admission test had a sensitivity of 66.7%, specificity of 93.3% and a positive predictive value of 53.3% for predicting an Apgar score < 5 at birth. Neonatal admission to neonatal intensive care unit was required in 1% of patients with a normal test and 33% of patients with an abnormal test (p <0.01). CONCLUSION: The result of admission cardiotocography testing could be used to identify patients likely to develop adverse foetal outcomes and help in optimal utilization of labour room resources.
