What is the purpose of this trial?

This trial tests a new method to treat brain bleeding by comparing two devices: IRRAflow and External Ventricular Drainage (EVD). IRRAflow actively removes fluid, blood, and bacteria from the brain, while EVD functions passively. The trial aims to determine which device is safer and more effective for individuals with specific types of brain bleeding or infection. Ideal candidates are adults requiring drainage treatment for conditions such as brain hemorrhages or ventriculitis. Researchers will monitor participants for a month after treatment to compare outcomes. As an unphased trial, this study allows participants to contribute to innovative research that could enhance future treatment options.

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the IRRAflow device is safe for brain hemorrhage treatment?

Research has shown that the IRRAflow system is generally safe and may cause fewer problems than traditional methods. Studies have found that it can clear brain bleeds faster than systems relying on gravity. By using controlled fluid flow to manage brain pressure, this system has been linked to better patient outcomes. While more research is needed to confirm these results, current evidence supports the safety of IRRAflow for treating brain bleeds. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about IRRAflow because it offers a unique approach to managing brain hemorrhage. Unlike standard treatments that use a simple external ventricular drain (EVD) to relieve intracranial pressure, IRRAflow actively exchanges fluids, potentially improving the clearance of harmful substances from the brain. This active fluid exchange system could lead to faster and more effective pressure reduction, offering hope for better outcomes for patients with brain hemorrhage.

What evidence suggests that the IRRAflow device is effective for brain hemorrhage?

Research has shown that the IRRAflow system, which uses active fluid exchange, effectively treats brain bleeds like intraventricular and subarachnoid hemorrhages. Studies have found that it clears blood faster than traditional methods, leading to better patient outcomes. Unlike passive systems that rely only on gravity, this system actively washes out blood. In this trial, participants may be randomized to receive the IRRAflow system. One study found that patients treated with IRRAflow had better results compared to those using standard drainage techniques, such as External Ventricular Drainage (EVD), which serves as the control treatment in this trial. This suggests that IRRAflow could be a promising option for managing brain hemorrhages. ^{3 5 6 7 8}

Trial Overview

The study compares two methods of draining harmful fluids from the brain: IRRAflow (an active system) versus a standard passive drain (EVD). Participants are randomly chosen to receive one method and monitored for a month to see which is safer and more effective.

How Is the Trial Designed?

Group I: IRRAflow with Active Fluid Exchange System (IRRAflow) Experimental Treatment 1 Intervention

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.

Group II: External Ventricular Drainage (EVD) Active Control 1 Intervention

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.

Published Research Related to This Trial

In a study of 115 heart failure patients, upgrading from an implantable cardioverter-defibrillator (ICD) to a cardiac resynchronization therapy defibrillator (CRT-D) showed a trend towards reduced ventricular arrhythmias (VA) in patients who responded positively to CRT, with a decrease from 0.51 to 0.30 episodes per year.

Conversely, patients who did not respond to CRT experienced a significant increase in VA episodes requiring device therapy, rising from 0.40 to 1.21 episodes per year, highlighting the importance of patient response to CRT in managing arrhythmia risk.

In a study of 130 patients undergoing external ventricular drainage (EVD) for conditions like subarachnoid hemorrhage and intracerebral hemorrhage, 27.6% developed infections related to the procedure, highlighting the importance of monitoring and minimizing the duration of EVD use.

The overall mortality rate was 46.9%, with significantly higher mortality observed in patients with lower Glasgow Coma Scores (GCS) at the time of EVD insertion, indicating that EVD should be used cautiously and only when absolutely necessary.

In a study of 155 acute brain-injured patients, EVD insertion was found to cause small hemorrhages and edema around the catheter, but these changes did not lead to neurological deterioration or increased intracranial pressure.

The average volume of hemorrhagic lesions increased from 8.16 ml to 15 ml over time, and factors like hypertension and multiple insertions were linked to a higher incidence of these hemorrhages, indicating a need for careful monitoring in at-risk patients.

Implantable cardioverter-defibrillators (ICDs) are highly effective in preventing sudden cardiac death from dangerous heart rhythms, with modern devices offering reliable detection and treatment options, including pain-free therapies.

While traditional transvenous ICDs are the most common due to their proven benefits and low risks, alternative configurations like subcutaneous ICDs and other extravascular approaches are being developed to address complications such as lead placement issues and infections, allowing for more personalized treatment options.

A systematic review and meta-analysis of 303 patients with intraventricular hemorrhage (IVH) found that patients treated with external ventricular drain (EVD) had a significantly higher risk of requiring a ventriculoperitoneal (VP) shunt compared to those treated with neuroendoscopic (NE) evacuation, with a relative risk of 1.93.

Despite the treatment method, the overall prognosis for patients with IVH remains poor, highlighting the need for large randomized controlled trials to better understand the benefits and outcomes of NE compared to EVD.
