ABSTRACT
Objective. To study the characteristics of cardiotocography (CTG) and pregnancy outcomes in patients who had a mild coronavirus infection in the third trimester. Patients and methods. The parameters and variations of CTG and pregnancy outcomes were analyzed in 32 low-risk pregnant women who experienced mild COVID-19 in the third trimester (the study group) and in 30 pregnant women (matched pairs) who had no coronavirus infection (the comparison group). Results. A total of 375 CTGs were analyzed 221 in the study group and 154 in the comparison group. Normal CTG recordings were found in 87% of pregnant women in the study group, which was significantly less frequent than in those without COVID-19 (97%) (p = 0.02), and suspicious CTG in 10 and 1.3%, respectively, which was 3.38-fold more frequent than in the comparison group (p = 0.04). Pathological CTG recordings were observed only in two women in the study group. The features of CTG in women who had a mild form of COVID-19 in the third trimester were a significant decrease in the number of accelerations, short-term variation (STV) in the range of 3 to 5 ms, long-term variation (LTV) <50 ms, a tendency toward tachycardia and low heart rate variability (<5 ms), and prolonged decelerations. The frequency of fetal asphyxia and neonatal morbidity was higher in the study group. Conclusion. COVID-19 even in its mild form may have a negative effect on the fetus, increasing the frequency of fetal hypoxia and neonatal asphyxia.Copyright © 2023, Dynasty Publishing House.
