Method for continuous conjunctival oxygen monitoring during carotid artery surgery.
A new device for measuring conjunctival oxygen tension (PcjO2) was used for intraoperative monitoring during carotid endarterectomy. The PcjO2 measures local tissue oxygenation and, thus, reflects the oxygen delivery to the areas supplied by the internal carotid artery. PcjO2 was found to be sensitive to manipulation, clamping, and obstruction of the carotid artery; it provided a useful monitoring system for assessment of the cerebral circulation during carotid surgery.
