Introduction:

previous studies have shown an increased incidence of all-cause postpartum hemorrhage during the COVID-19 pandemic. Placental accreta is a frequent cause of hemorrhagic shock.

Objective:

determine the severity of shock and the amount of bleeding during the COVID-19 pandemic in women diagnosed with placenta previa and placental accreta.

Material and methods:

in a comparative cohort study of women with placenta previa and accreta treated at the National Institute of Perinatology during the period from January 2017 to December 2019 group I (pre-pandemic) and from January 2020 to March 2022 group II (pandemic) the amount of hemorrhage and the class of hemorrhagic shock according to ATLS were compared between the groups.

Results:

277 women were studied, 211 were from group I (pre COVID-19) and 66 from group II (COVID-19). A greater amount of bleeding was observed during the COVID pandemic versus the pre COVID phase (2,150.56 ± 1,910.08 mL vs 1,246.34 ± 1,494.1 mL) p = 0.001, there were differences in the proportions of severity of hemorrhagic shock in the pandemic phase for classes III and IV.

Conclusion:

an increase in the amount of bleeding and severity of shock was found during the COVID-19 pandemic.
