KTG during pregnancy makes it possible to indirectly assess the state of the fetus - eliminate hypoxia (oxygen starvation) of the fetus and estimate the presence of a tone of the uterus or the development of generic activity.
Assign the CTG from 28-30 weeks of pregnancy, but it is possible to correctly interpret the results only with 32 weeks of pregnancy, when the fetal is formed by rhythmic shifts of sleep and wake periods. Normally, KTG during pregnancy is appointed no more than 1 time in 10-14 days, and during pathology, regularity is determined only by a doctor and can reach several times a day.
The study is carried out in the morning either in the evening when the fetal activity is the largest. Before studying for 1-2 hours, the patient should eat. The study is not carried out immediately after eating or intravenous infusion of glucose solution. Before studying the patient, it is desirable to empty the bladder, since sometimes the procedure can last more than 40-50 minutes, during the study the patient must be in a convenient position, preferably on the side, and not on the back, as it can cause the appearance of falsely negative results. The patient can read a magazine or a book, but it is undesirable to use mobile communications - this may interfere with the KTG apparatus. On average, the procedure lasts 30-40 minutes, but if necessary, the doctor may extend the study. Two sensors are attached to the belly of a woman - one registers the palpitations of the fetus, the second is the contractile activity of the uterus.
In our female consultation, this type of study is carried out in office No. 16 (2 floor w / c) in the direction of the district doctor of the obstetrician-gynecologist and at the coupon issued to them.
Cardiotocography - continuous simultaneous registration of the heart rate of the fetus and the tone of the uterus, the frequency of motor activity of the fetus with the graphic image of physiological signals on the calibration tape. Cardiotocography in the modern world is an integral part of a comprehensive assessment of the state of the fetus in conjunction with ultrasound and dopplerometry.
Cardiotocography (CTG) is a method of functional assessment of the state of the fetus during pregnancy and in childbirth on the basis of registration of the frequency of its heartbeat and their changes depending on the cuts of the uterus, the action of external stimuli or the activity of the fetus itself.
Use CTGs not earlier than with 32 weeks of pregnancy. By this time, the relationship between cardiac activity and motor activity of the fetus is being formed, which reflects the functionality of several of its systems (central nervous, muscular and cardiovascular).
The primary importance in assessing the state of the fetus has its activity. It is important that during the implementation of the CTG, at least part of the fetal activity period is accompanied by its movements. Taking into account the calm state of the fetus, the necessary overall duration of the recording should be 40-60 minutes, which minimizes a possible error in assessing the functional state of the fetus.
CTG indicators for pregnancy are needed as a comprehensive assessment of the state of the intrauterine fetus. Only an ultrasound or even dopplerography is not enough to find out if the child is enough oxygen.
during pregnancy shows how it transfers physical exertion (in particular, its movements and cuts in the uterus), whether it will be able to go through the natural generic paths and remain healthy.
In what cases is it necessary to conduct cardiotokography? Fisher scale, CTG norms. Diagnosis of the intrauterine state of the fetus in the frequency of its heartbeat. The doctors of the Art-Honey medical clinics are responsible for questions on the cardiographography of the fetus.
Active behavior of a pregnant woman during painting photography could affect the interpretation of the CGT data. The reactivity index shows the state of the vegetative nervous system of the fetus. Your CTG indicators correspond to the state of a healthy baby.
Apparently, we are talking about forming placental insufficiency. The walks here are completely nothing to see about impaired uterine-placental blood flow. You need adequate treatment and dynamic observation of the state of the fetus.
You should go to the reception to child or perinatal cardiologists, they will already make a conclusion about the further fate of the kid. It is possible that the genetic consultation will also need.
Adekvatably evaluate the CTG data carried out during the operation of the fetus, it is impossible. It is worth repeating the study during the maximum activity of the baby, usually this is an early morning clock or evening.
You can repeat the CGT the next day at the time of the maximum activity of the fetus. If the results are former, hospitalization will need. We can talk about placental insufficiency. Read more about this complication of the course of pregnancy in the section "Medical Publications".
Control over the state of the fetus is an important goal of a pregnant examination. It can be carried out by different methods. Cardiotocography is the most common, painless and affordable method of tool control of the state of the fetus.
Cardiotocography is a methodology for assessing the state of a fetus developing in the womb, which consists in analyzing changes in the frequency of its heartbeat at rest, during movements, as well as in response to the impact of external factors.
The technique of this study is based on a known to many Doppler effect. The hardware sensor creates special ultrasonic waves heading inside the organism and reflected from the medium surface with different sound conductivity, after which they are also fixed again. When the boundary of the media partition is shifted, for example, when the heart is moving, the frequency of the created and received ultrasonic wave becomes different. The time interval between each heart abbreviations is the frequency of heart abbreviations (CSS).
The goal of the CTG is the timely detection of deviations of the functional state of the fetus, which allows the doctor if they are preparing to choose the necessary therapy, as well as choose the appropriate time and the method of the delivery.
No special preparation for this study need. But to obtain reliable results during the study, the woman should be relaxed and located in a convenient position, do not move. Therefore, before the procedure is worth going in advance in the toilet.
It is recommended to take food for about 2 hours before the study, and it is impossible to conduct its empty stomach. In coordination with the doctor during the procedure, small snacks are resolved with something sweet if the baby is in the sleep phase to activate it. To prepare for this, you can get a sweet food in advance.
This type of prenatal diagnosis shows the dynamics of the fetus of the fetus, the frequency of its heart blows, motor activity. Indicators may vary depending on the time of day, the period of tolerance, the well-being of the mother and some irritants. KTG during pregnancy do not need to be perceived as a diagnosis. Modern equipment in the center "Eskulp +" works on the Doppler effect. Information in the form of numbers, sounds and light signals is displayed on the tape. The resulting pictures are called cardiotocograms.
Based on the obtained indicators, it is possible to find out the problems with health in time, to warn an accident during childbirth. Therefore, the value of KTG during pregnancy is difficult to overestimate. When problems detected, the doctor will conduct a correction of the pregnant woman, will prescribe or the opposite will cancel drugs.
For example, if the baby is di-stress, urgent therapy is needed, sometimes an artificial delivery. The life of the fetus is evaluated before childbirth or during them, the monitoring of the heart rate, the tone of the uterus.
Purpose of the CTR of the Fetal, Norma for weeks, measurement rules, as well as deviations possible with an increased or reduced indicator or change the speed of its increase.
