Abstract
-
BACKGROUND: During intracranial brain surgery, numerous factors may alter cerebral blood flow and the oxygen supply-demend balance. Continuous monitoring of the jugular bulb venous oxygen saturation (SjvO2) may help in the anesthetic management of such procedures.
METHODS
Fiberoptic SjvO2 was continuously monitored and recorded 1, 3 and 5 min after the skin incision, skull bone craniotomy, dura open and dura closure in 20 patients.
RESULTS
The SjvO2 was increased after the skin (scalp) incision at 1, 3 and 5 minutes and also after endotracheal suctioning for removal of secretions.
CONCLUSIONS
Although the accuracy of Fibroptic SjvO2 determination is limited, it allows the detection of cerebral blood flow and oxygen supply-demend imbalance during brain surgery. The frequent occurance of SjvO2 elevations is suggestive of reactive hyperemia mechaniams.
