Umbilical cord clumping consists in the binding of the umbilical cord by nipper to interrupt blood flow from placenta to foetus. Umbilical cord can be clamped within 30s or at least 1 min after birth. A lot of studies have shown that delayed umbilical cord clamping is associated with greater haemoglobin concentration, better iron storage between 3-6 months of life and lower incidence for transfusion and neonatal hypotension compared to immediate umbilical cord clumping. 

Newborns subjected to Caesarean Section showed greater value of haemoglobin and lower value of red blood cells compared to newborns birth by vaginal delivery. Despite evidence of beneficial effects for delayed umbilical cord clamping after eutocic delivery, this practice is not yet taken into consideration after elective Caesarean Section.
