Evaluation of the effect of SARS-COV-2 infection during pregnancy on fetal Doppler ultrasound parameters: A prospective study

Aim: The fetal effects of severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) infection have been the subject of controversy since the beginning of the pandemic. We aimed to investigate the effect of SARS-COV-2 infection on fetal Doppler parameters. Material and Methods: This prospective case-control study was conducted at Health Sciences University, Izmir Tepecik Education and Research Hospital between September 1, 2021, and June 1, 2022, on pregnant women confirmed to have SARS-CoV-2 by RT-PCR testing. Pregnant women who had mild to moderate coronavirus disease 2019 (COVID-19) infection during pregnancy were compared with a control group of pregnant women not infected with the COVID-19 virus. All Doppler and fetal biometry ultrasound assessments between 34 and 37 weeks of gestation were performed in our unit. Results: Pregnant women infected and not infected with COVID-19 were demographically homogeneous, and when they were compared in terms of fetal Doppler parameters, no statistically significant difference was observed. Conclusion: We consider that mild to moderate COVID-19 does not affect fetal well-being during pregnancy.
