A pilot exploratory investigation on pregnant women’s views regarding STan fetal monitoring technology.

A clear communication between maternity care providers and women about technology use in intrapartum care is of great value. This research is now being used to inform the implementation of the first properly powered Australian randomised trial comparing ST Analysis and CTG monitoring.

STAN clinical guidelines and the new FIGO CTG classification system

In 2015 the International Federation of Gynecology and Obstetrics (FIGO) presented a new classification system for interpretation of intrapartum CTG, replacing the old system from 1987. The new system is a 3-tier classification system instead of a 4-tier, where the preterminal CTG class has been omitted. Furthermore, the definitions of tachycardia and decelerations, and time durations of abnormal variability have been changed. All this with the aim to create a simple and more objective CTG classification system.
The new FIGO …

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
1.a Labour Ward Lead Consultant and Lead for Clinical Governance , St. George’s University Hospitals NHS Foundation Trust, St George’s University of London, London, UK.
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).
Table 1. The FIGO2015 intrapartum cardiotocography (CTG) classification system [3] in summary.

*) Decelerations are repetitive if they occur at >50% of uterine contractions.
a) Accelerations (amplitude >15 bpm, lasting >15 s …

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
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 …
