[Cerebral oxygen saturation and hemoglobin index under separate brain perfusion].
We monitored bilateral cerebral oxygen saturation and hemoglobin index while the brain received separate perfusion for major vascular surgery. Before surgery, left cerebral oxygen saturation and hemoglobin index were within normal limits but right cerebral oxygen saturation and right hemoglobin index were low. At the end of surgery, right cerebral oxygen saturation was elevated and almost equal to left cerebral oxygen saturation, and right hemoglobin index was elevated too but slightly lower than left hemoglobin index. We found that oxygen delivery to the right cerebral hemisphere improved in comparison with presurgical period. No paralysis or any other neurological complications occurred postoperatively. We conclude that such monitoring is useful during and after anesthesia under separate brain perfusion.
