The abrupt end of extracerebral contamination, caused by aortic clamping, affected both NIRS monitors to a considerable extent. Both the INVOS and the ForeSight-monitor were unable to detect severe cerebral hypoxia/anoxia under conditions of normal extracerebral oxygenation. While both NIRS-monitors may guide measures to optimize arterial oxygen supply to the head, they should not be used with the intention to detect isolated cerebral desaturations.
