The Australian Placental Transfusion Study (APTS): Should very pre term babies receive a placental blood transfusion at birth via deferring cord clamping versus standard cord clamping procedures?

A randomised two arm open label controlled trial comparing standard immediate cord clamping versus deferring cord clamping for 60 seconds or more in babies born less than 30 weeks of gestation to determine which cord clamping method results in improved survival and less disability.

Brief summary

Most preterm babies have the umbilical cord clamped within 10 seconds of birth. Placental transfusion is a simple way of giving the baby extra blood at birth by delaying the clamping of the umbilical cord by 60 seconds or more. There is promising evidence from randomised trials that placental transfusion in babies less than 37 weeks of pregnancy may improve their blood pressure, reduce the number of blood transfusions needed and decrease bleeding into the brain, bowel disease and infection. However, we not know if babies born before 30 weeks of pregnancy benefit or if placental transfusion increases or decreases death or childhood disability. Despite this uncertainty more doctors are recommending that all very preterm babies are given a placental transfusion at birth. It is important to find out if placental transfusion does more good than harm, before it becomes even more widely used. The Australian Placental Transfusion Study will enrol at least 1600 women who will give birth to babies born less than 30 weeks of gestation. These participants will be randomly assigned to either standard treatment where the umbilical cord is clamped within 10 seconds of birth or a second method where the umbilical cord will be clamped after waiting for 60 seconds or more at birth while the baby is being held below the level of the placenta. The main research question is whether placental transfusion reduces death and disability when the baby is discharged from hospital and into childhood.

Interventions

The intervention involves deferring clamping of the cord after birth. The obstetrician or midwife holds the baby as low as possible below the level of the placenta for 60 seconds or more and then clamps the cord 6 cm from the about 6 cm from the umbilicus.
