Quick Answer: At What Gestation Can You Do A CTG?

When can CTG be used?

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.

What is CTG in pregnancy?

Cardiotocography (CTG) is a technical means of recording the fetal heartbeat and the uterine contractions during pregnancy. The machine used to perform the monitoring is called a cardiotocograph, more commonly known as an electronic fetal monitor (EFM).

How are contractions measured?

However, an IUPC measures the frequency, duration, and intensity of contractions. The strength of the contraction is measured from the baseline (when the uterus is relaxed) to the peak of the contraction and is recorded in units-one unit is the amount of pressure it takes to raise a column of mercury one millimeter.

What is normal CTG?

Normal intrapartum CTG trace: The normal intrapartum CTG is associated with a low probability of fetal compromise and has the following features: • Baseline FHR is between 110-160 bpm. • Variability of FHR is between 6-25 bpm.

How CTG test is done?

How does cardiotocography (CTG) work? CTG uses sound waves called ultrasound to detect the baby’s heart rate. Ultrasound is a high-frequency sound that you cannot hear but it can be sent out (emitted) and detected by special machines. Ultrasound travels freely through fluid and soft tissues.

What do contractions feel like?

During contractions, the abdomen becomes hard. But labor contractions usually cause discomfort or a dull ache in your back and lower abdomen, along with pressure in the pelvis. Contractions move in a wave-like motion from the top of the uterus to the bottom. Some women describe contractions as strong menstrual cramps.

What is shouldering in Ctg?

Abbreviation: CTG, cardiotocography. * Regard the following as concerning characteristics of variable decelerations: lasting more than 60 seconds; reduced baseline variability within the deceleration; failure to return to baseline; biphasic (W) shape; no shouldering.

Is it normal for baby’s heart rate to drop?

In a healthy labor and delivery, the baby’s heart rate will drop slightly during a contraction, and then quickly return to normal once the contraction is over (2). Therefore, some variability in heart rate is to be expected: this shows as a jagged line on the monitor.

Why do they do fetal monitoring?

Doctors most often perform fetal heart monitoring in the delivery room. It’s critical for your doctor to monitor your baby’s heart rate throughout labor. The timing of your baby’s heartbeats can indicate whether they’re in distress or at physical risk.

Does baby move during contractions?

You’re Having Strong, Regular Contractions

You usually can’t feel your baby move during the cramp or contraction. The contractions push the baby’s head down, slowly thinning and opening the cervix; this is called effacement and dilation.

What does Toco mean on a CTG?

Cardiotocography (CTG) is a technical means of recording (-graphy) the fetal heartbeat (cardio-) and the uterine contractions (-toco-) during pregnancy, typically in the third trimester. The machine used to perform the monitoring is called a cardiotocograph, more commonly known as an electronic fetal monitor.

What are late decelerations?

Late decelerations are one of the precarious decelerations among the three types of fetal heart rate decelerations during labor. They are caused by decreased blood flow to the placenta and can signify an impending fetal acidemia.

How long do contractions last?

Early labor will last approximately 8-12 hours. Your cervix will efface and dilate to 3 cm. Contractions will last about 30-45 seconds, giving you 5-30 minutes of rest between contractions. Contractions are typically mild and somewhat irregular but become progressively stronger and more frequent.

What is a reactive CTG?

“Reactive” is defined as the presence of two or more fetal heart rate accelerations within a 20-minute period.

How do doctors monitor contractions?

The monitoring is usually performed in a doctor’s office or hospital. A nurse will wrap a belt around your waist and attach it to a machine called a tocodynamometer. The machine records the frequency and length of your contractions. Your doctor may also recommend monitoring your contractions at home.

How does a Tocodynamometer work?

Tocodynamometers are electronic devices for monitoring and recording uterine contractions during labor. They are applied to the lower part of the uterus using a belt. When the uterus contracts, it pushes against the intrauterine wall and makes internal pressure rise.

What is purpose of contraction?

Uterine contraction: The tightening and shortening of the uterine muscles. During labor, contractions accomplish two things: (1) they cause the cervix to thin and dilate (open); and (2) they help the baby to descend into the birth canal.

What are some signs that labor is nearing?

Look out for these 10 signs of labor that tell you baby’s on the way:

  • Baby “drops”
  • Cervix dilates.
  • Cramps and increased back pain.
  • Loose-feeling joints.
  • Diarrhea.
  • Weight gain stops.
  • Fatigue and “nesting instinct”
  • Vaginal discharge changes color and consistency.

How do contractions feel at first?

Early contractions may feel like period pain. You may have cramps or backache, or both. Or you may just have aching or heaviness in the lower part of your tummy. You may feel the need to poo or just feel uncomfortable, and not be able to pin down why.

Do contractions feel like you need to poop?

If you feel like you need to poop and your contractions aren’t back-to-back and extremely painful—you probably just need to poop. Poop happens in labor in tandem with all those contractions as a natural way to clean house in preparation for baby. If you’re not fully dilated or extremely close to it—go ahead and poop.
