OBJECTIVE: To demonstrate that delayed cord clamping (DCC) is safe in mothers with confirmed SARS‐CoV‐2 infection. DESIGN, SETTING AND PARTICIPANTS: Prospective observational study involving epidemiological information from 403 pregnant women with SARS‐CoV‐2 between 1 March and 31 May 2020. Data were collected from 70 centres that participate in the Spanish Registry of COVID‐19. METHODS: Patients' information was collected from their medical chart. MAIN OUTCOMES AND MEASURES: The rate of perinatal transmission of SARS‐CoV‐2 and development of the infection in neonates within 14 days postpartum. RESULTS: The early cord clamping (ECC) group consisted of 231 infants (57.3%) and the DCC group consisted of 172 infants (42.7%). Five positive newborns (1.7% of total tests performed) were identified with the nasopharyngeal PCR tests performed in the first 12 hours postpartum, two from the ECC group (1.7%) and three from the DCC group (3.6%). No significant differences between groups were found regarding neonatal tests for SARS‐CoV‐2. No confirmed cases of vertical transmission were detected. The percentage of mothers who made skin‐to‐skin contact within the first 24 hours after delivery was significantly higher in the DCC group (84.3% versus 45.9%). Breastfeeding in the immediate postpartum period was also significantly higher in the DCC group (77.3% versus 50.2%). CONCLUSIONS: The results of our study show no differences in perinatal outcomes when performing ECC or DCC, and skin‐to‐skin contact, or breastfeeding. TWEETABLE ABSTRACT: This study demonstrates that delayed cord clamping is safe in mothers with confirmed SARS‐CoV‐2 infection.
