title: Cerebral hypoperfusion during pediatric cardiac surgery detected by combined bispectral index monitoring and transcranial doppler ultrasonography.
abstract: Bispectral index monitoring (BIS) measures depth of anesthesia and sedation. The case of a neonatal patient who underwent surgical repair for a double aortic arch is presented. During surgery, BIS decreased to 0, and cerebral blood flow (CBF), as measured by transcranial doppler ultrasonography, could not be detected immediately after clamping of the arch. BIS returned to baseline, and CBF was detected only after the aortic arch was unclamped. The arch was then carefully reclamped during close BIS and CBF monitoring.
