title: [Influence of location for jugular venous blood sampling to cerebral circulatory index (CCI)].
abstract: When cerebral circulatory index (CCI) expressed as inverse of arterial-jugular venous oxygen content difference is measured, venous sampling at the internal jugular bulb needs to be done in order to avoid mixture with extra-cerebral perfusion blood. To estimate the validity of this point, difference of values calculated with blood obtained simultaneously at the jugular superior bulb, the inferior region and the cerebral sinus were examined in monkeys. As a result, no significant differences were found to result from location of the sampling, and significant correlation between PaCO2 and CCI was recognized. These findings supported the idea that CCI reflects the cerebral blood flow due to PaCO2 changes.
