説明
Normal values of changes in jugular O2 tension (PjO<sub>2</sub>) and cerebral blood flow (CBF) induced by carotid compression were measured in 9 healthy young men. The normal changing value of PjO<sub>2</sub> was 0.3±1.0mmHg, CBF 2.9±3.5ml/100g Brain/min. There were no effects on electroencephalogram (EEG) during carotid compression in the healthy young men.<br>In normal cerebral blood flow group, CBF changed from 59.9 to 62.9, PjO<sub>2</sub> from 33.3 to 32.9 on ipsilateral compression, and CBF changed from 59.9 to 59.1, PjO<sub>2</sub> from 33.3 to 32.9 on contralateral compression. In this group, there were no influences on PjO<sub>2</sub>, CBF and EEG during carotid compression.<br>In low cerebral blood flow group, CBF was reduced from 41.7 to 34.8, PjO<sub>2</sub> from 35.4 to 32.3 on ipsilaterat compression, and CBF from 41.7 to 40.0, PjO<sub>2</sub> from 35.4 to 35.1 on contralateral compression. During ipsilateral compression, it showed tendency of decreasing on CBF and PjO<sub>2</sub>, and ΔCBF was -6.7, ΔPjO<sub>2</sub>-3.1. 7 cases with EEG slowing on carotid compression exsisted in this group.<br>The cases with EEG slowing, who were certified occlusions and/or stenosis of carotid arteries or main cerebral arteries, had the significant CBF and PjO<sub>2</sub> reduction on carotid compression, and ΔCBF was -9.0, ΔPjO<sub>2</sub>-3.5.<br>It is concluded that digital compression of the carotid artery in the neck is the very useful method for testing the adequancy of cerebral collateral circulation observating PjO<sub>2</sub> and EEG.<br>Effects of respiration and blood pressure during carotid compression have to be kept in mind.
