COMPARISON OF PORTABLE ADVANCED INTRAPARTUM MONITORING SYSTEM AND STANDARD CARDIOTOCOGRAPHY FOR ASSESSMENT OF FOETAL HEART RATE.

Background: Perinatal deaths due to hypoxia are preventable with continuous monitoring. Cardiotocography (CTG) is standard for intrapartum foetal assessment, aiming to detect signs of distress and intervene promptly to mitigate risk. Objective: To determine the accuracy of advanced intrapartum monitoring system in comparison with electronic CTG in tracking of non-reassuring foetal symptoms by pattern analysis of the FHR. Materials and methods: A single-centre, observation study was conducted at a tertiary care hospital from January 2020 to December 2021. CTG and an advanced portable intrapartum monitoring system (KEYAR) were applied simultaneously to all participants. Twenty-minute-long recording traces were obtained from both devices. Mode of delivery was noted for all patients along with Apgar score at 1 minute and 5 minutes. Results: The final study cohort was constituted by 94 participants. Most participants (57.4%) were primigravida. The mean (95% CI) sensitivity, specificity, positive predictive value and negative predictive value of KEYAR tracing were 33% (9.6, 70), 97.7% (92.09, 99.37), 50% (15, 85) and 95.5% (89.12, 98.26), respectively. The overall, diagnostic accuracy of KEYAR was 93.6% (86.77, 97.04). Conclusions: Advanced portable intrapartum monitoring device (KEYAR) is a new application with the benefits of easy user operability and portability. [ABSTRACT FROM AUTHOR]
