Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Umbilical cord milking (UCM) - 32 opioid-using mothers will be randomly assigned to receive umbilical cord milking or standard cord clamping in the 2 weeks prior to birth. The Research Midwife/PI will be responsible for ensuring that the correct cord clamping technique is employed through notation on hospital records. An information sheet and video will be provided to all staff involved. Formal training will not be provided unless requested by staff. Note that this is a variation of normal cord clamping procedures, and does not disrupt the birth process.

Infants randomized to the UCM condition will have their umbilical cord clamped 20-30 cm from their body within 30-60 seconds of birth. The cord will then be cut, leaving the long section attached to the infant. This section of the cord will be squeezed slowly (‘milked’) towards the infant once or twice to push the blood within inside the infant’s body. The cord is then clamped closer to the infant and care proceeds as usual. Once each cord is milked, it will be measured (cut end to infant umbilicus).

Standard (or immediate) cord clamping refers to clamping of the cord within 15-60 seconds of birth (WHO).

Comparator / control treatment
16 pregnant women with no history of substance use across pregnancy will be recruited. No UCM will be administered to control participants, they will receive standard cord clamping. Standard (or immediate) cord clamping refers to clamping of the cord within 15-60 seconds of birth (WHO).

There is no control group receiving UCM in this design for two reasons: 1) obstetric and midwife staff conclude it would be difficult to recruit otherwise healthy pregnant women to receive UCM; 2) there would be a ceiling effect in these infants where UCM would not noticeably improve outcomes. Nonetheless, the control group is essential to provide a baseline reading across all measures while controlling for all external factors (e.g., socio-economic status) and to indicate a direction of change for the measures to be gathered i.e. whether infant inflammatory cytokines are higher or lower compared to controls, and whether the UCM normalises these values.
