TOBY Xenon Study

TOBY Xenon Study

Neuroprotective effects of Hypothermia combined with inhaled xenon following perinatal asphyxia

This is a proof-of-concept study to test the hypothesis that following perinatal asphyxia treatment with a combination of hypothermia and inhaled xenon reduces cerebral biochemical abnormality, preserves cerebral structures, and leads to improved clinical outcomes at hospital discharge.

Neonatal Clinical Magnet Group

There are three London centres participating in this trial: University College Hospital, St Thomas’s Hospital, Queen Charlotte’s Hospital.
