Public title Cord Pilot Trial
Scientific title Immediate cord clamping versus deferred cord clamping for preterm birth before 32 weeks gestation: a pilot randomised trial
Acronym CORD
Serial number at source 13070; 108150; 12OB006
Study hypothesis Our primary hypothesis is that for children born before 32 weeks gestation immediate cord clamping is associated with higher death or neurosensory disability at two years of age (corrected for gestation at birth) than deferred cord clamping. A trial to test this hypothesis would need to be large and multicentre. This protocol is for a pilot trial to assess the feasibility such a study.

Lay summary Background and study aims
In the UK one in every 70 babies is born more than eight weeks before their due date (very preterm). These very premature babies have immature lungs, and often need help with breathing, feeding and keeping warm. Usually at the birth of a premature baby, the umbilical cord is clamped and cut straight away, the baby is placed in a plastic wrap to retain heat, and then cared for by the neonatologist (a doctor or nurse who is a specialist in the care of newborn babies) on a special table at the side of the room.
Clamping the cord stops blood flow between the placenta (organ that connects the developing foetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply) and the baby. If the cord is not clamped straight away, this blood flow may continue for several minutes, potentially transferring blood from the placenta to the baby.
Waiting a few minutes before clamping the cord may help the baby to adjust to life outside the womb. As it is not known when the best time to clamp the cord for very preterm births is, this study is being done. The study is comparing clamping the cord after at least two minutes (deferred cord clamping) with clamping the cord within 20 seconds.
For deferred cord clamping, care for the baby will be provided at the woman’s bedside. If the cord is clamped within 20 seconds, the neonatal team will choose whether care for the baby is provided at the woman’s bedside or at the side of the room. In both cases the baby will receive the same care at birth, just in different places.
This is an initial small study, to help decide whether it would be possible to do a much larger trial. Finding out which of the two approaches to care is better for babies and their mothers will need the large study. Information from this study will help us to conduct the large study well.

Who can participate?
Women who are expected to give birth more than eight weeks before their due date.

What does the study involve?
Women who take part in the study will be randomly allocated to one of the two groups (1) cord clamping after at least two minutes, or (2) cord clamping within 20 seconds. If the cord is clamped after at least two minutes, care for the baby will be provided at the bedside. If the cord is clamped within 20 seconds, the neonatal team will choose whether care for the baby is provided at the woman’s bedside or at the side of the room.
Women who take part in the trial will be asked to complete a short postal questionnaire six weeks after the birth, and another one year after the birth. Around the child’s second birthday the parents will be contacted to complete another questionnaire and to arrange a visit to find out how their child is doing.

Target number of participants UK Sample Size: 110
Interventions 1. Deferred cord clamping: clamping the cord after at least two minutes.
2. Immediate cord clamping: clamping the cord within 20 seconds.
Primary outcome measure(s) For this pilot trial to assess feasibility of the main trial, outcomes will be:
1. Number of women recruited in each hospital
2. Proportion of potentially eligible women recruited
3. Reasons women are not recruited
4. Range of gestational age and outcome for the baby amongst women recruited
5. Compliance with the trial interventions (timing of cord clamping), and reasons for non-compliance
6. Completeness of data collection for main trial outcomes (see above)
7. Views of women and their partners on recruitment, randomisation and the trial interventions
8. Proportion lost to follow up after discharge from hospital, and reasons for loss to follow up
Secondary outcome measure(s) No secondary outcome measures
