Perinatal Outcomes and Hematologic Parameters in COVID-19 Pregnancies
2020年8月14日 更新者：Esin Merve Erol Koç、Ankara City Hospital Bilkent
Comparison of Hematological Parameters and Perinatal Outcomes in COVID-19 Pregnancies and Healthy Pregnancy Cohort
Complete blood count parameters are routinely evaluated cost-effective markers in diagnosis and clinical follow-up of infectious diseases.There is increasing number of studies to report the course of COVID-19 in pregnancy.
The current study aimed to elucidate the changes in hematologic parameters in response to SARS-CoV-2 infection and whether there was an increase in adverse perinatal outcomes such as increased neonatal intensive care unit admission and lower APGAR scores in pregnancies with COVID-19.

详细说明
The objective of this study is to evaluate the relationship between Coronavirus Disease 2019 (COVID-19) in pregnancy and adverse perinatal outcomes.
The secondary aim is to analyze the diagnostic value of hematologic parameters in COVID-19 complicated pregnancies.The current study is conducted in a high volume tertiary obstetrics center burdened by COVID-19 pandemics, in Turkey, between March 20 and July 25, 2020.
The study included a pregnant women cohort who had been regularly followed up and delivered in our clinics.
The cohort was divided into two groups to reveal the impact of COVID-19 on the complete blood count cell indices and unfavorable obstetric and early neonatal outcomes in pregnant women.
The clinically confirmed diagnosis of COVID-19 cases were included in Study Group (n=39) the healthy pregnant women without COVID-19 were included in Control Group (n=69).
The study achieved a power of 0.89 and 0.98 with a 5% level of significance.
