Abstract/OtherAbstract:
Using the open ventriculocisternal perfusion method, rates of cerebrospinal fluid (CSF) production and reabsorption by bulk flow were examined in dogs anesthetized with either enflurane (2.2%) in nitrogen (60-70%) and oxygen, or nitrous oxide (60-70%) and enflurane (less than 0.2%) in oxygen (controls). The mean rate of CSF production increased significantly with enflurane (2.2%), from 0.055 +/- 0.020 ml/min (mean +/- SD) in controls to 0.082 +/- 0.033 ml/min (n = 12). After this initial increase of approximately 50%, the production rate decreased significantly by about 7.4%/h. When the expired concentration of enflurane was decreased from 2.2% to less than 0.2%, the mean rate of CSF production decreased to control values at 45-50 min. An intracerebral accumulation of CSF resulting from this enflurane-induced increase in CSF production may contribute in part to increased intracranial pressure when the dura is intact.
