What is the Stan system of fetal monitoring?

The STAN system includes a fetal ECG electrode, a maternal skin reference electrode, and a microprocessor-based monitor that identifies the fetal ST segment and T-wave changes and compares them with the normal baseline values that have been individually established for that patient using the fetal heart rate monitoring …

What is Stan analysis?

ST analysis (STAN) involves a combination of fetal heart rate. interpretation and analysis of the fetal electrocardiogram. STAN has been available for over 5 years in the UK and is used in. some, but not all, maternity units.

How does electronic fetal monitoring work?

Continuous electronic fetal heart monitoring may be used during labor and birth. An ultrasound transducer placed on the mother’s abdomen conducts the sounds of the fetal heart to a computer. The rate and pattern of the fetal heart are displayed on the computer screen and printed onto special graph paper.

What is Foetal bradycardia?

Fetal bradycardia is defined as a baseline fetal heart rate less than 110 beats per minute for at least 10 minutes. Evaluation and management may differ for antenatal and intrapartum fetal bradycardia and depends on gestational age.

What does a normal CTG look like?

Normal antenatal CTG trace: The normal antenatal CTG is associated with a low probability of fetal compromise and has the following features: Baseline fetal heart rate (FHR) is between 110-160 bpm • Variability of FHR is between 5-25 bpm • Decelerations are absent or early • Accelerations x2 within 20 minutes.

What is suspicious CTG?

8.3 Suspicious If the CTG trace is categorised as suspicious: • Correct any underlying causes, such as hypotension or uterine hyperstimulation. • Perform a full set of maternal observations. • Start one or more conservative measures. • Inform an obstetrician or a senior midwife .

How do doctors confirm pregnancy by checking pulse?

To do so, place your index and middle fingers on the wrist of your other hand, just below your thumb. You should be able to feel a pulse. (You shouldn’t use your thumb to take the measurement because it has a pulse of its own.) Count the heartbeats for 60 seconds.

What does active labor look like on monitor?

Contractions are in red. When you’re looking at the screen, the fetal heart rate is usually on the top and the contractions at the bottom. When the machine prints out graph paper, you’ll see the fetal heart rate to the left and the contractions to the right.

How is the Stan method used for ECG?

The method consists of a device with all the standard CTG functions plus ST Analysis, the method shows the fetus’s ECG waveform measured with an electrode applied to the fetus’s scalp. This provides a continuous and central message from the fetal heart – minute by minute.

Which is more accurate the Stan method or CTG?

Standard CTG has a high specificity for classification of normality and severe pathological traces. That is why we have developed the STAN Method, an unique analysis tool for fetal monitoring. The combination of ST-Analysis and standard CTG parameters provides extended and more accurate information about the fetus during labour than CTG alone.

What are the results of the Stan method?

Several major randomised trials and many observational studies have been published with conclusive results: ST Analysis makes it easier to monitor the fetus’s wellbeing. ST Analysis has contributed to a reduction in neonatal metabolic acidosis, fetal scalp blood sampling and the number of operative deliveries around the world.

What are the different types of cardiotocography methods?

Cardiotocography (CTG) 1 Method. Simultaneous recordings are performed by two separate transducers, one for the measurement of the fetal heart rate and a second one for the uterine contractions. 2 Interpretation. A typical CTG output for a woman not in labour. 3 Accelerations. 4 Decelerations.
