NCT06303349

Brief Summary

The objective is to create a dynamic clinical prediction model that includes routinely measured care and biological biomarkers to predict cerebral vasospasm within 14 days of bleeding in patients treated in the neurosurgical intensive care unit for subarachnoid hemorrhage. Patients admitted to intensive care will be followed for up to 14 days (D14 time horizon of interest), or until discharge from intensive care if earlier. Blood samples will be taken from D1 to D10 to isolate the blood biomarkers of interest for each patient. The measurement of biomarkers and cerebral vasospasm will be blinded to each other.

Study Arms (1)

experimental arm

EXPERIMENTAL

Patients with subarachnoid hemorrhage, whether aneurysmal or non-aneurysmal, who were admitted to the neuro-resuscitation unit within four days of onset. Diagnosis was based on clinical presentation and confirmed by brain imaging

Other: Samples collection

Interventions

from D1 to D10, 1 SSTII (Serum separator tubes II) dry tube of 6 mL blood and 1 EDTA (Ethylenediamine tetraacetic acid) tube of 6 mL blood are collected. 1 SSTII dry tube of 6 mL cerebral spinal fluid will be collected distally in external ventricular drain, after eliminating the dead volume of the collection burette, for patients with it.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subarachnoid hemorrhage (of aneurysmal or non-aneurysmal etiology) less than 4 days prior to admission to neuro-resuscitation, diagnosed on clinical presentation and confirmed by brain imaging.
  • Free, informed and written consent signed by the patient (or, failing this, his or her representative).
  • Patient entitled to or affiliated with social security

You may not qualify if:

  • Significant vasospasm on admission to the department, diagnosed on initial imaging
  • Patient whose short-term survival (48 hours) appears compromised
  • Contraindication to perfusion CT scan
  • Pregnant or breast-feeding women
  • Patient under legal protection (persons deprived of liberty or under guardianship)
