Abstract
Following birth, a sample of blood can be taken from the umbilical cord to assess the metabolic status of the infant at birth, and to determine whether any significant intrapartum oxygen deprivation may have occurred. These samples are most often taken following clamping of the umbilical cord, which necessitates that the cord be clamped shortly after birth in order to prevent time-dependent changes in cord blood gas values. However, cord bloods can be taken from an unclamped cord, allowing the infant the benefits of optimal cord clamping. In addition, whether these bloods are taken routinely or only where indicated varies depending on local guidelines.
