ST waveform analysis vs. cardiotocography alone for intrapartum fetal monitoring: A systematic review and meta-analysis of randomized trials

Abstract

Key message: ST waveform analysis is purposed to be better for labor surveillance than conventional CTG. We quantified the efficacy of these two methods, assessing quality of the scientific evidence with the GRADE tool, and determined that evidence is insufficient to justify the use of ST waveform analysis as intrapartum monitoring.
