Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Placental Cord Drainage
- ie. immediate clamping and cutting of the placental cord at caesarean section, followed by drainage of the placental side of the cord into a receptacle).
- this will be performed by the operating surgeon (ie. Consultant Obstetrician or Obstetrics Registrar)
- this is a once-off procedure, at the time of elective caesarean section
- this will occur in theatre at an urban hospital, with Obstetrics services
- adherence to the intervention/control will be documented at the time of caesarean, and rationale for deviation will be documented. If not documented at the time, patient medical record will be consulted by study team to determine a possible rationale.
Intervention code [1] 320781 0
Treatment: Surgery
Comparator / control treatment
Delayed Cord Clamping
- ie. clamping and cutting of the placental cord after at least 60 seconds to allow possible perfusion of blood from placenta to neonate
- this will be performed by the operating surgeon (ie. Consultant Obstetrician or Obstetrics Registrar)
- this is a once-off procedure, at the time of elective caesarean section
- this will occur in theatre at an urban hospital, with Obstetrics services
- adherence to the intervention/control will be documented at the time of caesarean, and rationale for deviation will be documented. If not documented at the time, patient medical record will be consulted by study team to determine a possible rationale.

Efficacy
Statistical methods / analysis
Cochrane review demonstrated a >40% reduction in time to delivery of placenta at vaginal delivery. Studies have suggested approximately 200 seconds for delivery of placenta at caesarean section. Using a conservative 180 seconds +/- 90 seconds as the baseline time of delivery of placenta at caesarean section, and a conservative 33% reduction (60 seconds), the required power is 35 patients per group.
Using 50 patients per group to allow for uncertainty translating Cochrane findings at vaginal delivery to caesarean section.
