Monitoring of Cerebral Oxygenation in the Intensive Care Nursery
Prime objectives in neonatal intensive care include prevention of brain injury and maintanance of normal neurologic function. Since brain function is dependent upon adequate oxygen delivery, various techniques for oxygen monitoring have become integral parts of neonatal intensive care. However, most monitoring techniques currently in use determine oxygenation at sites distant from the brain (i.e. aorta, skin) and do not directly assess either cerebral oxygen delivery or oxygen utilization by the brain. Thus, an instrument which can provide continuous information on hemoglobin oxygenation and on cerebral oxidative metabolism may have marked advantages over current monitoring capabilities and offer the opportunity to observe the specific effects of medical therapies and nursing care on the infant’s cerebral oxygenation.
