Pupillometry : Predictive Indicator in External Ventricular Drain Clamping ?


Brief description of study

Pupillar diameter variation to predict success or failure of external ventricular derivation clamping.

Pupillometry utilisation as a diagnostic tool in external ventricular clamping test in neurological ICU should improve patients care in several ways :

  • earlier use of ventriculo-peritoneal or ventriculo-atrial shunts to shorten the external ventricular treatment duration and thus reduce risks of infection and hospital stay duration
  • limit the medical imagery prescription and radiation exposition
  • avoid neurological deterioration linked to the external ventricular drain clamping in case of the pupillometric parameters variation would be earlier than clinical signs

Clinical Study Identifier: NCT03823430
