Features of the course of the early neonatal period in newborns from mothers who underwent COVID-19 during pregnancy (pilot prospective cohort study)

Objective: analysis of the course of the early neonatal period in newborns from mothers who underwent COVID-19 at different gestation periods. Materials and methods. Full-term children under the age of 7 days of life born in the Regional Perinatal Center of Kursk in 2021 were under observation: group 1 - as a result of pregnancy complicated by COVID-19 infection (47 people); group 2 - control group (31 people). The main indicator of the study is the pathological nature of the course of the early neonatal period. Results. The anthropometric data at birth did not differ significantly. Transient neonatal tachypnea (19.1% in group 1 versus 9.6% in group 2, respectively), intrauterine pneumonia (19.1% in group 1 versus 3.2% in group 2, respectively; both had bilateral p values = 0.040) were detected more frequently in newborn infants. Conclusion. COVID-19 infection during pregnancy was found to be a risk factor for the development of respiratory disorders in newborns in the early neonatal period. When interpreting these data, the limitations of the study should be taken into account: the sample size, the observational nature of the study, and the methods used to measure the indicators.
