Fetal CTG

During pregnancy, it is vital not only to manage the expectant mother’s health but also to consistently evaluate the fetus’s functional status and well-being. For this purpose, cardiotocography (CTG) is used – a completely safe and widely implemented prenatal screening method that allows clinicians to continuously monitor the fetal heart rate, motor activity, and uterine contractions.

CTG is considered one of the most critical evaluation methods used during late pregnancy and active labor. It helps the physician understand exactly how the fetus responds to the intrauterine environment, verifies that the baby receives an adequate supply of oxygen, and determines whether closer clinical surveillance or additional diagnostics are required.

At VitaMed Medical Center, CTG examinations are performed using modern electronic monitoring systems under the supervision of highly experienced specialists.

What Is CTG?

Cardiotocography (CTG) is a non-invasive prenatal diagnostic method that simultaneously records three vital parameters:

• Fetal heart rate (FHR) dynamics
• Fetal body movements
• Uterine contractions

Analyzing this combined data allows the obstetrician to accurately assess the fetus’s functional state and detect potential deviations or patterns of distress early. CTG is entirely safe for both mother and fetus, meaning it can be performed repeatedly throughout the final stages of pregnancy based on medical indications.

Key Parameters Evaluated by CTG

During the monitoring session, several critical physiological metrics are analyzed to determine fetal health:

• Fetal Heart Rate: The system continuously records the baseline fetal heart rate, which typically ranges from 120 to 180 beats per minute (bpm).
• Fetal Heart Rate Variability: The specialist evaluates the natural, beat-to-beat fluctuations in the cardiac rhythm. This metric provides vital information regarding the health of the fetal central nervous system and overall physiological resilience.
• Fetal Motor Activity: The device logs fetal movements, allowing the physician to analyze heart rate accelerations in direct response to them.
• Uterine Contractions: CTG accurately measures the frequency, duration, and intensity of uterine contractions, which is particularly essential during the final weeks of gestation and throughout labor management.

When Is Fetal CTG Monitoring Necessary?

Cardiotocography is routinely integrated into prenatal care pathways after week 28 of pregnancy as a vital component of third-trimester screening. Your obstetrician-gynecologist may prescribe a CTG session if:

• The pregnancy has entered the third trimester.
• There is a noticeable decrease or change in fetal movements.
• Fetal hypoxia (oxygen deprivation) is clinically suspected.
• The patient is managing a high-risk pregnancy profile.
• A comprehensive assessment of fetal well-being is required.
• The estimated due date is approaching. CTG is also heavily utilized in delivery rooms for continuous, real-time fetal monitoring during labor.

How Is the CTG Procedure Conducted?

During the session, the expectant mother rests comfortably in a reclined or seated position. Highly sensitive external sensors (transducers) are secured to the abdomen using soft elastic straps to record the necessary physiological data.

CTG is completely painless, non-invasive, and requires no injections or specialized interventions. A standard monitoring session typically lasts between 20 and 40 minutes. In certain instances – such as when the baby is in a natural sleep cycle and less active – the physician may extend the monitoring duration to ensure a complete and accurate diagnostic reading.

No special physical preparation is required prior to a CTG appointment. We recommend arriving for your session in a relaxed state and informing your doctor of any new symptoms or changes in your well-being.

Why Choose VitaMed for Prenatal Monitoring?

At VitaMed Medical Center, CTG tracking is an integral part of our comprehensive prenatal care system. Our specialists do not simply print out the monitoring data; they systematically cross-reference your CTG charts with your overall pregnancy history, previous ultrasound findings, and current clinical parameters. This meticulous oversight ensures complete peace of mind for the mother and total safety for the baby.

Frequently Asked Questions

• Is CTG completely safe for my baby? Yes, absolutely. CTG utilizes passive ultrasound technology and pressure sensors. It emits no harmful radiation, is entirely non-invasive, and is trusted by obstetricians worldwide.
• At what week of pregnancy can I start having CTG scans? CTG is typically introduced after the 28th week of gestation, when the fetal nervous system is sufficiently mature to provide diagnostic heart rate reactivity. Your doctor will determine the exact schedule based on your clinical needs.
• What can a CTG strip reveal to the doctor? A CTG strip reveals the baseline fetal heart rate, patterns of accelerations and decelerations, the baby’s heart rate reactivity to physical movements, and the presence or absence of uterine contractions.
• Will it affect the results if the baby is asleep during the test? Yes. If the fetus is in a sleep phase, the heart rate variability may temporarily decrease. If this occurs, the physician will simply extend the session or use gentle methods to wake the baby to ensure a conclusive reading.
