How do you assess a CTG?
How do you assess a CTG?
To interpret a CTG you need a structured method of assessing its various characteristics….The most popular structure can be remembered using the acronym DR C BRAVADO:
- DR: Define risk.
- C: Contractions.
- BRa: Baseline rate.
- V: Variability.
- A: Accelerations.
- D: Decelerations.
- O: Overall impression.
What is normal CTG in pregnancy?
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 a fetal assessment?
A fetal ultrasound (sonogram) is an imaging technique that uses sound waves to produce images of a fetus in the uterus. Fetal ultrasound images can help your health care provider evaluate your baby’s growth and development and monitor your pregnancy.
What is CTG in fetal monitoring?
Cardiotocography (CTG) is a continuous electronic record of the baby’s heart rate obtained via an ultrasound transducer placed on the mother’s abdomen. It is sometimes referred to as ‘electronic fetal monitoring’ (EFM).
What is an abnormal CTG?
An abnormal CTG has two or more features which are non-reassuring, or any abnormal features. Further information about classifying FHR traces: If repeated accelerations are present with reduced variability, the FHR trace should be regarded as reassuring.
When should you start CTG monitoring?
Continuous CTG monitoring should start late in the first stage of labor and during the expulsion stage. However, in high-risk pregnancies (s.
What can indicate fetal distress?
Signs of fetal distress may include changes in the baby’s heart rate (as seen on a fetal heart rate monitor), decreased fetal movement, and meconium in the amniotic fluid, among other signs.
How reliable is CTG?
Cardiotocography (CTG) has a 99.8% false positive rate in predicting CP, a very rare event.
How accurate is CTG?
While specific abnormalities of the FHR pattern on CTG are proposed as being associated with an increased risk of cerebral palsy (Nelson 1996), CTG specificity to predict cerebral palsy is low, with a reported false positive rate as high as 99.8%, even in the presence of multiple late decelerations or decreased …
What are the signs of a baby in distress?
Are there studies comparing no fetal monitoring with Continuous CTG?
No data were found comparing no fetal monitoring with continuous CTG. Overall, methodological quality was mixed. All included studies were at high risk of performance bias, unclear or high risk of detection bias, and unclear risk of reporting bias. Only two trials were assessed at high methodological quality.
What is the purpose of continuous Cardiotocography ( CTG )?
Read the full abstract… Cardiotocography (CTG) records changes in the fetal heart rate and their temporal relationship to uterine contractions.
How does continuous Cardiotocography ( CTG ) affect women in labour?
Continuous CTG also makes moving and changing positions difficult in labour and women are unable to use a birthing pool. This can impact on women’s coping strategies. Women and their doctors need to discuss the woman’s individual needs and wishes about monitoring the baby’s wellbeing in labour.
How is the baby’s heartbeat recorded in a CTG machine?
A baby’s heartbeat can be monitored intermittently using a special trumpet-shaped device, or hand-held Doppler device. The heartbeat can also be checked continuously using a CTG machine. Continuous CTG produces a paper recording of the baby’s heart rate and the mother’s labour contractions.
