Description of intervention(s) / exposure
NIRTURE trial will be a single-blinded randomised controlled trial with two parallel groups that are stratified for site and gestational age (less than 26 weeks and greater than or equal to 26+0 – 28+6 weeks gestation). Enrolment will occur after birth of the baby. After enrolment, infants will be randomised to either control group or intervention group. For all enrolled babies, monitoring of cerebral oxygenation will be commenced by placement of a non-adhesive probe on the fronto-parietal region of the forehead within 6 hours of birth and monitoring will be continued for 5 days.

For the intervention group, the cerebral oxygenation (crSO2) reading is visible and the baby will be treated according to a dedicated clinical guideline when the cerebral oxygenation is outside the range of 65% to 90%. The probe will be moved every 4 hours. The intervention will be delivered by the bedside medical and nursing team using a treatment algorithm. Research team will review the adherence to the protocol with bedside forms when the crSo2 is is less than 65% or more than 90%. The dedicated clinical guideline was designed based on the evidence that affected regional oxygen saturation. Cerebral oxygen monitoring and intervention will cease after 5 days of age.

Comparator / control treatment
For the Control group, cerebral oxygenation reading is NOT visible and the baby will be treated according to standard clinical practice (as per local site practices, that is if the baby has hypotension based on blood pressure monitoring, then a bolus of normal saline followed by inotropes if required is commenced). We will perform blinded cerebral oxygenation monitoring (we will cover the monitor) and the information will not be available to clinicians to act upon.

Eligibility
Key inclusion criteria
• Preterm infants (singleton or twin births) less than 29 weeks gestation who are either inborn (born at the local study site hospital) or outborn (born outside the local study site hospital) and less than 6 hours of age when admitted to the study site NICU.
Minimum age
0 Hours
Maximum age
6 Hours
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria

• Infants with an antenatal or postnatal diagnosis of major congenital anomaly requiring major surgery or a genetic disorder associated with neurological impairment.
• Multiple births beyond twins are excluded for practical reasons (sites may not have additional NIRS monitors and the rates of multiple births beyond twins in Australia and New Zealand is very low < 2%).

Statistical methods / analysis
A 50% reduction in mean burden of hypoxia and hyperoxia in active treatment relative to control would be considered worthwhile. This corresponds to a reduction of 0.3 in the mean of log-transformed burden. In the Safe BoosC II study (BoosC results) a 58% reduction was achieved. Assuming a standard deviation of 0.5 in log-transformed burden (Ref – BoosC protocol), this would require 45 babies per group to achieve 80% power at 5% two-sided alpha. To account for the clustering effect of twins being allocated to the same treatment, we assume that 30% of babies are twins (giving an average cluster size of 1.3, and a within-twin correlation of 0.1 in the outcome. This gives a design effect of 1.03 by which the sample size is adjusted, leading to a sample size of 47 per group, 94 babies in total. We aim to recruit 100 babies to account for some loss to follow-up or missing data.

Summary
Brief summary
Preterm babies can develop brain injury which leads to long-term developmental problems. Most brain injuries occur within the first 5 days of life and protection of the brain during this critical period is essential. Fluctuating brain oxygen levels is one reason for brain injury to develop, which can also cause bleeding in the brain. Keeping brain oxygen levels in a specific range may be protective. The purpose of the study is to investigate in preterm babies, whether it is possible to keep brain oxygen levels in a specific range for the first 5 days by NIRS monitoring and following a dedicated clinical treatment guideline. We hypothesise that a combination of brain oxygen monitoring and offering treatment when brain oxygen levels are outside the range may reduce fluctuations in brain oxygen levels and reduce brain injury. Babies in this study will have either (a) the usual treatment (given to all babies), or (b) they will be in the group where the focus is on keeping brain oxygen levels in a specific range for the first 5 days of life using NIRS monitoring.
