Does CTG show contractions?

Does CTG show contractions?

Cardiotocography (CTG) measures your baby’s heart rate. At the same time it also monitors the contractions in the womb (uterus). CTG is used both before birth (antenatally) and during labour, to monitor the baby for any signs of distress.

How can you tell contractions from CTG?

One transducer records the fetal heart rate using ultrasound and the other transducer monitors the contractions of the uterus by measuring the tension of the maternal abdominal wall (providing an indirect indication of intrauterine pressure). The CTG is then assessed by a midwife and the obstetric medical team.

What is a normal CTG result?

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 suspicious CTG?

The FIGO guidelines can be used both antepartum and intrapartum. The moment one of the specified criteria is defined as suspicious or pathological, the entire CTG is considered suspicious or pathological. The CTG reading is also classified as pathological if two supicious criteria coincide (s. Table 5).

When is CTG done?

Antenatal CTG is most commonly performed in the third trimester of pregnancy (after 28 weeks).

When is CTG done pregnancy?

It may be used in isolation, sometimes referred to as the ‘non‐stress test’ or with the stimulation of uterine activity to see how the fetal heart responds, sometimes known as the ‘contraction stress test’ (Owen 2001). Antenatal CTG is most commonly performed in the third trimester of pregnancy (after 28 weeks).

Does Continuous CTG during labour improve neonatal wellbeing?

CTG during labour is associated with reduced rates of neonatal seizures, but no clear differences in cerebral palsy, infant mortality or other standard measures of neonatal wellbeing. However, continuous CTG was associated with an increase in caesarean sections and instrumental vaginal births.

What does an abnormal CTG mean during pregnancy?

Cardiotocography (CTG) is used during pregnancy to monitor the fetal heart and contractions of the uterus. It is most commonly used in the third trimester. Its purpose is to monitor fetal well-being and allow early detection of fetal distress. An abnormal CTG indicates the need for more invasive investigations…

What are the guidelines for interpretation and response to CTG patterns?

This document provides guidelines for clinicians in CTG interpretation and response to the CTG pattern of fetuses greater than 28 weeks gestation. It defines a standardised process of interpretation, documentation and management of cardiotocographs (CTG), in particular where variations from ‘normal’ occur.

What should I do if a CTG is interpreted as abnormal?

Note: in cases where a CTG has been interpreted as abnormal or is of concern, the on-duty or on-call consultant obstetrician must be notified and the notification, discussion and outcome documented in the woman’s record.
