  • Research summary

    Babies who are born very early (<26 weeks of pregnancy) are at high risk of developmental problems.

    Better medical knowledge and technology have improved survival rates for babies born very early but there has been no real improvement in the numbers of these children who grow up with disabilities.

    Sleep is very important for brain development and overall growth for babies and the neonatal intensive care unit (NICU) is very different to the environment in the womb. Medical alarms from essential equipment can create sudden increases in noise levels that can wake a sleeping baby and cause changes in heart rate and blood pressure.

    This study will observe the brain oxygen levels and the sleep-wake activity in babies to everyday noises in the NICU. Small non-invasive sensors will be placed on the infants head: one will measure the changes in oxygen levels in the brain in response to noise; the second will monitor the electrical activity and show the sleeping cycles of the baby. Ambient background noise and noise levels inside the infants incubator will also be monitored in the range that the human ear hears.
