NCT05386303

Brief Summary

The aim of this study is to assess the diagnostic ability of quantitative pupillometry for the early detection of hydrocephalus during the weaning process of the external ventricular drain.

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.

    5 days

Secondary Outcomes (8)

  • Diagnostic evaluation

    5 days

  • Pupillometry and EVD occlusion test

    5 days

  • Dilatation velocity

    5 days

  • Maximum constriction velocity

    5 days

  • Latency of contraction

    5 days

  • +3 more secondary outcomes
