Saline flushing of the pleural space using a new irrigation device

A Pilot Assessment of the Safety and Efficacy of Pleural Irrigation for Retained Pleural Infection Using a Novel Irrigation Device

Not applicable Interventional Beth Israel Deaconess Medical Center · NCT06727578

This pilot tests whether flushing the pleural space with sterile saline using the CLR irrigator can help clear retained infected pleural fluid in patients who cannot receive standard intrapleural enzyme therapy.

What this trial studies

This is a single-arm pilot in which patients with retained pleural effusion identified by bedside ultrasound within 24 hours of chest tube insertion receive intrapleural saline irrigation delivered with the CLR irrigator. The trial enrolls patients who are contraindicated for intrapleural enzymatic therapy and excludes non-infectious effusions and post-procedural empyema. Key outcomes include radiographic and clinical clearance of retained fluid, need for additional invasive procedures, and safety/tolerability. The procedure is performed and monitored at Beth Israel Deaconess Medical Center.

Who should consider this trial

Good fit: Adults with retained infected pleural fluid seen on bedside ultrasound within 24 hours after chest tube placement who cannot receive intrapleural enzymatic therapy are the intended candidates.

Not a fit: Patients with pleural fluid from non-infectious causes (for example malignancy) or with post-procedural empyema or complicated parapneumonic effusion are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this approach could clear infected pleural collections without enzymatic therapy and reduce the need for additional invasive procedures.

How similar studies have performed: Intrapleural enzymatic therapy (tPA/DNase) has demonstrated benefit in pleural infection, but saline irrigation with the CLR device is a novel approach with limited prior data and is being tested here as a pilot.
