Abstract

Background: Perinatal deaths due to hypoxia are preventable with continuous monitoring. Cardiotocography (CTG) is stan- dard 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.
