Press Release: Neoventa Introduces the STAN S41, Fetal Heart Monitor

Mölndal, Sweden – May 23, 2017: Scandinavian medtech pioneers, Neoventa, today announced their new STAN S41, Fetal Heart Monitor.
The STAN S41 was developed in collaboration with Sunray Medical Apparatus Co., Ltd, and is the only CTG (cardiotocograph) monitor in the world that incorporates ST Analysis.
ST Analysis is an evidence based method that gives you a continuous and central message from the fetal heart during labour. “It is a great support for the obstetric staff and provides, ‘a second pair of …

STAN and the new FIGO consensus guidelines on intrapartum CTG monitoring

The International Federation of Gynecology and Obstetrics (FIGO) presented in 2015 an updated intrapartum CTG classification system to replace the system from 1987. The CTG classification used in the STAN CTG+ST interpretation algorithm is basically a modified version of the FIGO 1987 classification system. The new FIGO system differs from the CTG classification used with STAN in the definitions of a normal FHR baseline, normal variability, variable decelerations, repetitiveness of decelerations, and the number of CTG classes. The new FIGO …

Fetal Electrocardiograph (ST-Analyser or STAN) for intrapartum fetal heart rate monitoring: a friend or a foe?

Chandraharan E

Abstract
Cardiotocograph (CTG) is associated with a high false positive rate of up to 60% which may increase the risk of unnecessary intrapartum interventions (emergency caesarean sections or operative vaginal deliveries) without any significant benefits. A recent study on variation of caesarean section rates in England has concluded that there was a very …

Swedish study investigates discrepancies between CTG classification systems, and the impact on ST event significance.

The STAN Clinical Guidelines classification system of cardiotocography (CTG) [1] is originally based on the FIGO classification system from 1987 [2]. In October 2015, the FIGO Intrapartum Fetal Monitoring Expert Consensus Panel presented their new CTG intrapartum classification system (FIGO2015) [3] (Table 1).

Why was a meta-analysis performed with primary endpoints considered clinically unimportant?

Letter to the Editor accepted in AOGS regarding the latest Meta Analysis:
Why did the authors perform a meta-analysis of studies with primary endpoints they consider clinically unimportant?
Kessler et al. 2016
DOI: 10.1111/aogs.12876
 
ABSTRACT
The meta-analysis of Blix et al. on ST waveform analysis (STAN) (1) confirmed the results of a previous meta-analysis (2). Their conclusions, however, are based on presuppositions that are highly questionable. The systematic review by Blix et al. (1) was prompted by a recently published American RCT …

Belittling of a significant decline in neonatal metabolic acidosis rate achieved by STAN monitoring

Letter to the Editor accepted in AOGS regarding the latest Meta Analyses:
Belittling of a significant decline in neonatal metabolic acidosis rate achieved by STAN monitoring
Per Olofsson1,2,
DOI: 10.1111/aogs.12861
Abstract:
Blix et al. found in a recent meta-analysis (MA) that intrapartum fetal surveillance with ECG ST analysis (STAN) results in a significant 36% decrease in metabolic acidosis at birth compared to cardiotocography (CTG) alone (1). This demonstrates that STAN monitoring could better than CTG alone protect against hypoxia proceeding to metabolic …

The 2015 FIGO classification of intrapartum cardiotocography: differences to the STAN classification

The STAN Clinical Guidelines classification system of cardiotocography (CTG) [1] is originally based on the FIGO classification system from 1985 [2]. In October 2015, the FIGO Intrapartum Fetal Monitoring Expert Consensus Panel presented their new CTG intrapartum classification system [3] (Table 1).
Table 1. The 2015 FIGO intrapartum cardiotocography (CTG) classification system [3] in summary.

*) Decelerations are repetitive if they occur at >50% of uterine contractions.

Comments on Blix et al. ST waveform analysis vs. cardiotocography alone

Some topics in obstetrics are more hot than others and we are in the remarkable situation that there are now more meta-analyses (MAs) than randomized controlled trials (RCTs) on the evidence for using fetal ECG ST analysis for fetal surveillance in labor. Previously six MAs (Neilson, 2012; Becker et al., 2012; Potti & Berghella, 2012; Salmelin et al., 2013; Schuit et al., 2013; Olofsson et al., 2014) on five RCTs (Westgate et al., 1993; Amer-Wåhlin et al., 2001; Ojala et …
