Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Infants randomised to the intervention arm will receive 15ml/kg of appropriately cross-matched, leucoreduced red blood cells from cytomegalovirus-negative donor, irradiated on the day of blood transfusion ('freshly irradiated red blood cells') in Wellington Neonatal Intensive Care Unit (NICU). Transfusion will be given through a cannula inserted by a qualified doctor working in Wellington NICU, and will be administered over 3hours by the registered nurse looking after the participating infant on the day of study transfusion.

Treatment: Other
Comparator / control treatment
Infants randomised to the control arm will receive 15ml/kg of appropriately cross-matched, leucoreduced red blood cells from cytomegalovirus-negative donor, irradiated and stored for up to 14 days (as per the current ANZSBT guidelines) in Wellington NICU. Transfusion will be given through a cannula inserted by a qualified doctor working in Wellington NICU, and will be administered over 3hours by the registered nurse looking after the participating infant on the day of study transfusion.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is done in the Blood Bank (away from NICU study site), and the outcome of allocation is concealed from the study investigators, participants, and medical/nursing staff looking after the participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation sequence was generated using www.sealedenvelope.com
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data
Intervention assignment
Parallel
Other design features
Phase
Not Applicable
Type of endpoint/s
Efficacy
Statistical methods / analysis
Based on the post-hoc analysis from a recent study completed (NIMO-AI), a sample size of at least 60 infants is required to detect a difference of 5% in cerebral tissue oxygenation immediately after transfusion between the intervention and control groups, with power of 0.96 and p-value of 0.05 (t-test, G power 3.1)
