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

Background

Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near‐infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients.

Objectives

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