BACKGROUND Care for women during the third stage aims to reduce the risk of major haemorrhage, but is very variable. The current World Health Organisation (WHO) recommendation is that care should include administration of a uterotonic (oxytocin, if it is available) soon after birth of the baby, delayed cord clamping, and delivery of the placenta by controlled cord traction. METHODS To ascerta...

We describe the relation between umbilical cord clamping time and two different enrichment system of CD34(+) stem cells from umbilical cord blood with the proliferative ability and bone marrow reconstitution of the stem cells obtained. After an obstetrician performed the cord blood collection, the purification of stem cells was performed either with a combination of monoclonal antibodies (negat...

Experimentally, a typical ∼2-min cord clamp-to-ventilation interval in preterm lambs is accompanied by increased hemodynamic lability of the birth transition. However, whether this lability is related to development of asphyxia after cord clamping, or can be avoided with a shorter clamp-to-ventilation interval, is unknown. To address these questions, anesthetized preterm fetal lambs (gestation ...

Umbilical cord clamping at birth has a major impact on an infant's cardiovascular system that varies in significance depending upon whether the infant has commenced breathing. As umbilical venous return is a major source of preload for the left ventricle during fetal life, recent experimental evidence has shown that clamping the umbilical cord severely limits cardiac venous return in the absenc...

Background: Recently, late umbilical cord clamping is generally recommended, which decreases neonatal anemia; however, it may also increase jaundice and some other poor outcomes. Objectives: We here attempted to determine whether actually increases the incidence of phototherapy for outcomes term “low-risk newborns”. Methods: With approval Brazilian Registry Clinical Trials (REBEC), a total 357 ...

Amale neonateweighing 3838 g was born at 39weeks of gestation by elective cesarean delivery due to breech presentation. The umbilical cord was clamped by the surgeon approximately 20 cm from the umbilical base and the neonate was transferred to the midwife for final clamping. The cord was clamped again at approximately 3 cm from the umbilical base. The residual umbilical cord was approximately ...
