Dr. Timonen from Turku University Hospital, Finland presented a poster with their experience of ST Analysis at the recent Soc. for Maternal-Fetal Medicine (SMFM) congress in Dallas USA. The rate of metabolic acidosis was reduced with 79% when the first four years of ST Analysis usage were compared to the six following years in patients monitored with CTG+ST. During the same period the number of fetal scalp blood measurements was substantially reduced as well as the rate of total cesarean …

In the European Stan Expert meeting in 2009, the interpretation of a high baseline T/QRS ratio at the start of a registration was discussed since some cases with high baseline T/QRS followed by metabolic acidosis had been encountered.  The baseline T/QRS is the absolute value of the T/QRS ratio at the start of a Stan recording, and is currently only used for comparison with later changes indicating a rise in the T-wave of the fetal ECG.
The objective of this …

The objective of this meta-analysis, which includes five randomised trials (RCT) and 15,352 patients, was to compare the effects of adding ST Analysis to conventional intrapartum CTG. The included RCT’s evaluated singleton term pregnancies in cephalic presentation and the meta-analysis was performed on results for metabolic acidosis, fetal blood sampling, mode of delivery, Apgar score and neonatal care. For three of the studies, published corrected data were used and the meta-analysis could be performed on all data according to the …

First decide what protocol and server type to use. FTP and HTTP/WebDAV are the easiest to implement, while HTTP/POST is intended for more advanced server applications, e.g. when the recording file is to be added to a digital patient record or similar.Install the server application and decide what kind of authorisation is to be used. Although anonymous access is supported, Neoventa recommends that, when not using anonymous access, a unique account is created on the server for the STAN devices, …

The aim of this prospective randomized study was to compare the effectiveness of pulse oximetry and ST Analysis of the fetal ECG, and to determine which method was better at identifying the labour which could continue to deliver a healthy newborn.

One hundred eighty women with a full-term, singleton, cephalic presentation and a CTG tracing with non-reassuring fetal heart rate (NRFHR) were included in the study. The rate of caesarean delivery, indication for operative delivery due to NRFHR and neonatal acid-base status was compared between the groups.

The study showed a significant difference in mode of delivery, in that the rate of caesarean section was 37% lower in the group monitored with ST Analysis. The authors conclude that both methods can prolong labour in situation with NRFHR, but that ST Analysis was more effective in safely avoiding emergency caesarean deliveries, and that this method also provided a more continuous source of information on fetal status throughout labour.

Edwin Chandraharan (MBBS, MS (Obs&Gyn), DFFP, DCRM, MRCOG) is the Lead Consultant Labour Ward & Lead Clinical Governance in Obstetrics and Gynaecology at St. George’s University Hospital in London, UK and has been working with ST Analysis since 2002.
Can you tell us about your first experiences of STAN and ST Analysis?
ST Analysis was introduced to St. George’s Hospital by my predecessor Mr. Austin Ugwumadu and Professor Sir Sabaratnam Arulkumaran in 2002. Initially we had only four STAN ST …

The County Council’s Committee on Knowledge Management (KUST) made the decision in early September that the STAN-method, which is the method developed by Neoventa, will not be used during childbirth in the Stockholm County. The recommendation is to use the method only in a controlled clinical trial to make further scientific evaluation possible.
KUST based its decision on a recently published report from the Method Council for the Stockholm County Council – Region Gotland, “Fetal monitoring with computerized ST analysis …

Kommittén för Kunskapsstyrning (KUST) inom Stockholms Läns Landsting beslutade i början av september att STAN-metoden, det vill säga den metod som Neoventa har utvecklat, inte ska användas vid förlossningar inom Stockholms Läns Landsting. Om metoden ska användas får det endast ske inom ramen för en kontrollerad klinisk studie.
KUST bygger sitt ställningstagande på en rapport som Metodrådet vid Stockholms Läns Landsting – Region Gotland nyligen publicerade; “Fetal monitoring with computerized ST-analysis during labor – a systematic review” (Rapport 2011:3).

The US National Institute of Health (NIH) is conducting the largest trial ever within obstetrics. The purpose of this research study is to see if Stan and ST Analysis will have an impact on newborn health in the United States, as it has been shown to have in Europe. The study is currently recruiting, and the goal is 11,000 patients to be included until 2012. For more information Click here
