Cerebral near-infrared spectroscopy (NIRS) for perioperative monitoring of brain oxygenation in children and adults

To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with no cerebral oxygenation monitoring or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of CDEs, neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay).

This is a protocol.
