Low flow hypothermic cardiopulmonary bypass, deep hypothermic circulatory arrest, and regional low-flow cerebral perfusion are special techniques used to facilitate complex intracardiac and aortic surgery in neonates and infants. Each carries a risk of cerebral hypoxia and neurologic morbidity. Neurologic monitoring in the form of near-infrared spectroscopy for cerebral oxygenation, transcranial Doppler ultrasound, and the bispectral index electroencephalogram can monitor the brain during these techniques to determine the minimum acceptable bypass flow rates or maximum acceptable duration of deep hypothermic circulatory arrest. The use of this monitoring has the potential to improve long-term neurologic and developmental outcome.
