OBJECTIVE: To evaluate safety and haematological effects of delayed cord clamping (DCC) in infants with expected low birthweight born in a resource-poor setting.

METHODS: Randomised controlled trial involving pregnant women in early labour ≥18 years with intrapartum symphysal-fundal height ≤32 cm. Mothers were randomised for either early cord clamping (ECC, <30 s) or DCC (2-3 min after birth).

RESULTS: We included 104 vigorous infants born by vaginal delivery, of whom 39% had a birthweight <2500 g. Infant haemoglobin (Hb) levels 24 h after birth were significantly higher in the DCC group (18.0 g/dl vs 16.8 g/dl, P = 0.006). Despite successful placental transfusion, hyperbilirubinemia and hyperviscosity were not observed. Two months after birth, there were no differences in Hb between groups (9.9 g/dl vs 9.8 g/dl, P = 0.60), but the infants in the DCC group had better weight gain from baseline than those with ECC (2.2 kg vs 1.9 kg, P = 0.058).

CONCLUSIONS: In this South African cohort of newborns with a subnormal distribution of birthweight delayed cord clamping was a safe procedure. Two months after birth the effect of DCC on Hb was not detectable anymore. DCC should be promoted in every singleton delivery in a resource-poor setting irrespective of the birthweight.
