Outcome Measures
Primary Outcomes (1)
NPi (Neurological Pupil index) and EVD (external ventricular drain)occlusion test
NPi will be compared between two groups of patients (constituted a posteriori): success and failure of the EVD occlusion test. Independently of this study, the EDV occlusion test starts as soon as prescribed by the physician as a prerequisite before its withdrawal. Failing an occlusion test is defined by the need for reopening the EVD.
