Abstract
OBJECTIVE: To determine the maternal and perinatal impact of pregnant women with SARS-CoV-2 positive polymerase chain reaction during childbirth and post clinical period. METHOD: Observational descriptive, retrospective, and multicentre study carried out through the review of clinical records of pregnant women admitted for delivery from 1 March to 30 June 2020. RESULTS: Thirteen women with SARS-CoV-2 positive polymerase chain reaction were tested. The prevalence of positive cases was 0.48% of the total number of births attended during the study period. None of the mothers developed complications from COVID-19 infection, nor did they require admission to the Intensive Care Unit. Of the births,15.4% ended in caesarean section, 7.7% were premature, 53.8% of the newborns were isolated from their mothers, 61.5% had late clamping of the umbilical cord and the rate of exclusive breastfeeding at discharge was 76.9%. All the newborns were polymerase chain reaction-negative for COVID-19 and had no postpartum complications. CONCLUSIONS: Vertical transmission during childbirth in newborns of COVID-19 positive mothers has not been reported. Clinical practices not supported by scientific evidence were detected at the beginning of the pandemic and adapted to international recommendations as the pandemic evolved.
