Death risk factors in parturients infected by sars-cov-2

Objective: To investigate the existence of a relationship between the risk of death of newborns and pregnant women infected with SARS-CoV-2. Material: Medical records of patients admitted to José Pedro Bezerra Hospital, in the city of Natal-RN, Brazil, from January 2020 to December 2021, totalizing 6,353 deliveries, of which 2725 were vaginal deliveries and 3628 were cesarean deliveries. Method: Review of medical records to collect data on gestational age, risk of death in infected parturients with SARS-CoV-2and relationship of severity of infection depending on blood group. Results: With regard to the blood groups of the total of 135 pregnant women who had a positive RT-PCR test, 59 are from blood group “O” (43.7%), 49 are blood group “A” (36.3%), 20 from blood group “B” (14.8%) and 7 from blood group “AB” (5.2%), an expected result since this is the incidence of blood groups in our population. Of the 35 pregnant women who went to the ICU, 14 (40%) are blood group “A” and of these,five died together with their NB. With the same prevalence (40%), patients of blood group “O” five went to the ICU, all of them survived and of these three of their NB died. Of the patients of blood group “B”, sixwere hospitalized in the ICU and only one of them died together with her NB. In patients with the blood group “AB”, only one patient was admitted to the ICU, but she survived as well as her newborn. Conclusions: The blood group of infected patients did not influence the severity of the disease; however, their comorbidities were a determining factor for the severe condition they presented.
