Elevated CSF PressureIf the CSF pressure is 25 cm of CSF and there are symptoms of increased intracranial pressure during induction therapy, relieve by CSF drainage (by lumbar puncture, reduce the opening pressure by 50% if it is extremely high or to a normal pressure of 25 cm of

9、 CSF and symptoms, repeat lumbar puncture daily until the CSF pressure and symptoms have been stabilized for 12 days and consider temporary percutaneous lumbar drains or ventriculostomy for persons who require repeated daily lumbar punctures Permanent VP shunts should be placed only if the patient is receiving or has received appropriate antifungal therapy and if more conservative measures to control increased intracranial pressure have failed. If the patient is receiving an appropriate antifungal regimen, VP shunts can be placed during active infection and
