Umbilical cord clamping and skin-to-skin contact in deliveries from women positive for SARS-CoV-2: a prospective observational study. BJOG. 2021 Apr; 128(5): 908-15. DOI: 10.1111/1471-0528.165971470-0328http://hdl.handle.net/10230/47655Objective: 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.application/pdfengThis is the pre-peer reviewed version of the following article: Mejía Jiménez I, Salvador López R, García Rosas E, Rodriguez de la Torre I, Montes García J, de la Cruz Conty ML, et al.
