Summary  Introduction: delayed umbilical cord clamping has the benefit of reducing the number of blood transfusions and the incidence of intraventricular hemorrhage in preterm infants, including the prevention of childhood anemia. The aim of this study is to determine the effects of late clamping on capillary oxygen saturation and value the presence of maternal and neonatal complications in the early hours of adaptation to extra-uterine life. Material and methods: in 19 infants who underwent the cord clamping the umbilical cessation of heartbeat, showed the passage of blood through the continuous monitoring of changes in weight. The average time of cessation of the heartbeat of the umbilical cord was 2'39" (± 2'27"). It is controlled specifically capillary oxygen saturation, reaching 89% (± 4,6%), 94% (± 4,1%) and 96% (± 3,8%) at 5, 10 and 15 minutes of life respectively. The temperature after 10 minutes of life was 36,6°C ± 0,6°C. After 48 hours of hospitalization were not found jaundice requiring phototherapy or cardiovascular or respiratory complications. Nor are differences found in maternal hematimetric values before delivery and the postpartum period or immediate delivery. Conclusions: waiting for the cessation of heartbeat umbilical cord was not associated with complications in mothers or in adapting to extra-uterine life of newborn babies within 48 hours of life
