Objectives To investigate the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on fetal Doppler parameters. Methods This was a prospective case-control study conducted in Ankara City Hospital with confirmed SARS-CoV-2 infected pregnants between August 1, 2020 and October 1, 2020. There were 54 COVID-19 confirmed pregnant women and 97 age-matched pregnant women as a control group between 28 and 39 weeks. Infection was confirmed based on positive real-time polymerase-chain reaction results. Demographic features, uterine artery (right, left), umblical artery, middle cerebral artery, ductus venosus, cerebro-placental ratio, and cerebral-placental-uterine ratio Doppler parameters were investigated in both groups. Results Two groups were similar in terms of demographic features and no difference was found for fetal Doppler parameters. Conclusions COVID-19 seems to have no adverse effect on fetoplacental circulation in mild and moderate patients during the acute phase of the infection.

COVID-19 感染孕妇胎儿多普勒参数的评估：一项前瞻性病例对照研究


目的 探讨严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 对胎儿多普勒参数的影响。方法 这是在2020年8月1日至2020年10月1日期间在安卡拉市医院进行的一项前瞻性病例对照研究，其中包括54名确诊的COVID-19孕妇和97名年龄匹配的孕妇。作为28至39周期间的对照组。根据实时聚合酶链反应阳性结果确认感染。对两组的人口统计学特征、子宫动脉（右、左）、脐动脉、大脑中动脉、静脉导管、脑胎盘比值和脑胎盘子宫比值多普勒参数进行了研究。结果两组人口统计学特征相似，胎儿多普勒参数无差异。结论 COVID-19似乎对轻、中度患者感染急性期的胎儿胎盘循环没有不良影响。
