Study summary

The goal of this clinical trial is to evaluate efficacy and safety of evacuation of cerebrospinal fluid, blood, and harmful bacteria from the intraventricular, subdural and subarachnoid spaces by Active Controlled Irrigation and Drainage (IRRAflow) compared to Passive External Ventricular Drainage (EVD).

Subjects with intraventricular hemorrhage, subarachnoid hemorrhage, subdural bleeding, and ventriculitis will be randomized to receive the IRRAflow device or EVD device and followed for one month post-procedure to compare outcomes between the subject groups.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Age ≥18 years of age
  2. Need of drainage for one of the following underlying conditions: Intraventricular hemorrhage, intracranial hemorrhage, subarachnoid hemorrhage, chronic subdural hematoma and ventriculitis
  3. Indication for active treatment evaluated by treating physician for underlying conditions; Intraventricular hemorrhage, subarachnoid hemorrhage, chronic subdural hematoma and ventriculitis
  4. Signed obtained by subject or Legally Authorized Representative

Exclusion criteria

Exclusion Criteria:

  1. Subject has fixed and dilated pupils
  2. Pregnant women
  3. Presence of Moyamoya
  4. History or presence of clotting disorder.
  5. count less than 100,000, greater than 1.4
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Study arms

  • Experimental
    IRRAflow with Active Fluid Exchange System (IRRAflow)

    Subjects may be randomized to receive the IRRAflow with Active Fluid Exchange System (intervention) for intracranial pressure monitoring and for externally draining intracranial fluid as a means of reducing intracranial pressure.

    Device: IRRAflow with Active Fluid Exchange System

  • Active comparator
    External Ventricular Drainage (EVD)

    Subjects may be randomized to receive an External Ventricular Drain (control) for intracranial pressure monitoring and for externally draining intracranial fluid as a means of reducing intracranial pressure.

    Device: External Ventricular Drain

Interventions

  • DeviceIRRAflow with Active Fluid Exchange System

    IRRAflow® Active Fluid Exchange System is an intracranial drainage system intended for use by professional medical hospital personnel, trained and experienced in neurosurgical medical care. The intracranial pressure is kept at a safe level by draining excessive intracranial fluid. The system incorporates an irrigation support mechanism, used to irrigate the system in a controlled, programmed manner to minimize catheter occlusion. Additionally, a manual bolus can be given to facilitate keeping the catheter clear of occlusion or to clear the catheter of occlusion if one is present. This mechanism works by producing a bolus pulse using short periods of high flow (i.e. flow pulses).

    Also known as: IRRAflow

  • DeviceExternal Ventricular Drain

    The External Ventricular Drain (EVD) is used standard of care at the study site for ventricular drainage.

    Also known as: EVD

What researchers measure

Primary outcomes

  1. Rate of revision procedures for the IRRAflow and EVD/Drainage catheters

    Time frame: Immediately post-procedure

Secondary outcomes

  1. Time to clearance of blood or bacterial mass as measured by head CT scan

    Time frame: Immediately post-procedure

  2. Rate of catheter-related infection

    Time frame: Immediately post-procedure

  3. Length of ICU stay

    Time frame: Baseline

  4. Rate of shunt dependency

    Time frame: Immediately post-procedure

  5. Indwell time of EVD/Drainage and IRRAflow Catheter

    Time frame: Immediately post-procedure

  6. Functional Status - at inclusion and 30 days

    The Modified Rankin Scale will be used to assess functional status. The Modified Rankin Scale ranges from 0 (no disability) to 6 (death).

    Time frame: 30 days post subject discharge

  7. Mortality rates - intraprocedural and at 30 days

    Time frame: 30 days post subject discharge

  8. Functional Status - at inclusion and 30 days

    The Extended Glasgow Coma Scale will be used to assess functional status. Results range from 1 (death) to 8 (upper good recovery).

    Time frame: 30 days post subject discharge

  9. Functional Status - at inclusion and 30 days

    The Barthel Index will be used to assess functional status. Scores for this assessment tool range from 0 - 100, with a higher number indicating a better functional status.

    Time frame: 30 days post subject discharge

  10. Functional Status - at inclusion and 30 days

    The Stroke Impact Scale will be used to assess functional status. Scores for this scale range from 0 - 100, with a higher number indicating a better functional status.

    Time frame: 30 days post subject discharge

  11. Functional Status - at inclusion and 30 days

    The EQ-VAS will be used to assess functional status. Participants rate their health from 0 (worst imaginable health) to 100 (best imaginable health).

    Time frame: 30 days post subject discharge
