Meta-Analysis shows significant improvements with ST-analysis

The March 2013 American Journal of Obstetrics and Gynecology (AJOG) included a publication by Schuit et al. entitled “Effectiveness of electronic fetal monitoring with additional ST analysis in vertex singleton pregnancies at >36 weeks of gestation: an individual participant data meta-analysis (MA).” Since the publication of the AJOG article, there have been two Letters to Editor, one from Prof. Rosen and a response from the authors, regarding issues with this particular MA. We encourage you to read these letters (on-line) since they provide further information and serve to answer a few open questions raised by the original article.

One of the important points, recognized by both sides in this discourse, is that there appears to be a learning curve (as with any new technology). In fact, analysis of the second half of the IPD MA showed statistically significant reduction of metabolic acidosis, admission to NICU and composite adverse neonatal outcome for CTG+ST compared to CTG alone. The attached “article summary” presents information from the recent MA showing this impact as well.   This MA provides additional evidence to our long-held belief that implementation of ST Analysis of the fECG as an adjunct to CTG will result in improved outcomes. If your labour ward has not yet experienced these evidence based benefits, we look forward to the opportunity to introduce you to ST Analysis and the Stan monitor!
