Application in obstetric practice of automated antenatal cardiotography method allows to eliminate subjectivity and to raise reliability of fetus condition estimation in group of pregnant woman of high obstetric and perinatal risk. It is established that in group of pregnant women with high risk of fetus condition infringement at cardiotocography dynamic supervision reveal already in II trimester. Herewith the earliest and authentic indicators of fetus condition infringement are: decrease variability basal rhythm fetal heart rate, absence of high variability or prevalence episodes of low variability over high, value of STV-short variability indicators less than 4.0. The obtained data allows to recommend application automated antenatal cardiotocography method in group of pregnant women with high perinatal risk for early diagnostics of fetus functional condition infringement. Possibility to estimate severity level of fetus metabolic acidosis will allow to solve in time issues of optimal obstetric tactics in pregnancy conducting, term and a method of delivery at this category of pregnant women

AbstractObjective:The objective of this study is to investigate the alterations caused by smoking on the features of fetal heart rate (FHR) tracings as well as to make a comparison between pregnant smokers and pregnant women with intrauterine growth restriction (IUGR).Study design:A number of established features derived from linear and nonlinear fields were employed to study the possible influence of maternal smoking on FHR tracings. Moreover, correlation and measures of complexity of the FHR were explored, in order to get closer to the core of information that the signal of FHR tracings conveys. Data included FHR tracings from 61 uncomplicated singleton pregnancies, 16 pregnant smoker cases, and 15 pregnancies of women with IUGR.Results:The analysis of FHR indicated that some parameters, such as mutual information (P=0.0025), multiscale entropy (P=0.01), and algorithmic complexity (P=0.024) appeared decreased in the group of pregnant smokers, while kurtosis (P=0.0011) increased. The comparison between pregnant smokers and pregnant women with IUGR indicated a reduction in Hjorth complexity (P=0.039) for the former.Conclusion:Smoking during pregnancy seems to induce differences in several linear and nonlinear indices in recordings of FHR tracings. This may be the consequence of an altered neurodevelopmental maturation possibly resulting from chronic fetal hypoxemia in cigarette-exposed fetuses.

The objective: to establish the features of fetus functional state definition in pregnant women with perinatal losses in history. Patients and methods. 89 pregnant women with perinatal losses in history were screened. The fetus functional status evaluation was based on cardiotocography and definition of fetal heart rate variability by cardiointervalography. Results. Received data showed the decrease of SDNN, RMSSD and pNN50 in pregnant women with perinatal losses in history, indicating the prevalence of parasympathetic effects on the fetal myocardium (p<0.05). Studies of mathematical time characteristics of fetal heart rate revealed a significant overweight of the metabolic-humoral regulatory circuit in women with normal pregnancy (p<0.05). Dynamic stress index evaluation indicates the centralization of heart rate regulation and significant intensity of the fetal compensatory mechanisms in pregnant women with perinatal losses in history. The cardiotocography revealed no difference between the fetal status in women of comparative groups (p>0.05). Conclusions. In pregnant women with perinatal losses in history owing to autonomic nervous system disregulation a significant intensity of fetal regulatory systems and the centralization of fetal cardiac rhythm control were observed. The cardiotocography and cardiointervalography data with revealed signs of excessive sympathetic activation can serve as preclinical signs of gestational pathology. Key words: perinatal losses, fetal functional state evaluation, cardiotocography, cardiointervalography, autonomic nervous system.
