Use of Lumbar Drain to Remove Clots in Patients Admitted to the Neuro-ICU After Subarachnoid Hemorrhage.
Use of Lumbar Drain to Remove Clots in Patients Admitted to the Neuro-ICU After Subarachnoid Hemorrhage.
Recently, a clinical trial showed that the use of lumbar drains compared to ventricular drain
 in patients suffering from subarachnoid hemorrhage resulted in less delayed ischemic
 neurological deficits but failed to show a clinical benefit after 6 months. The underlying
 assumption was, that the cerebrospinal fluid (CSF) obtained from lumbar drains has a higher
 concentration of blood than CSF from lumbar drains. The investigators decided to test this
 assumption. In this study, the investigators will randomize patients to either placement of a
 ventricular or a lumbar drain and analyze the CSF drainage on a daily basis.
Inclusion Criteria:
