Comparison of Early Pleural Irrigation Strategy With Saline to the Standard of Care for the Management of Complicated Pleural Infections.

Recruiting now · Phase 3

Conditions studied: Therapy, Pleural Infections

In brief

Intrapleural enzyme therapy (IET) is regarded by recent guidelines as a "rescue" therapy for managing complicated pleural infections; however, it is associated with significant side effects, including pleural bleeding, pain, and fever. Pleural irrigation with saline may serve as an alternative, yet evidence supporting its effectiveness is limited to a single small- scale, single-center randomized trial. The objective of the study is to compare the risk of treatment failure at 30 days (defined as a composite outcome that includes death, the need for thoracic surgery, or additional intrapleural enzyme therapy) between an early pleural irrigation strategy and standard care for complicated pleural infections.

You may qualify if…

• Adults (≥18 years old) capable of fully understanding the study;
• Complicated pleural infection (macroscopically purulent fluid, positive for bacteria on Gram's staining, positive on culture for bacterial infection, loculated effusion, pH <7.2, great abundance) leading to thoracic drainage;
• Initial ultrasound evaluation to estimate pleural fluid abundance and detect fibrinous septation;
• Social security affiliation
• Written informed consent
• Highly effective contraceptive methods for women of childbearing age include: Combined hormonal contraception (estrogen and progestogen) associated with inhibition of ovulation (oral, intravaginal, transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable); intrauterine device; hormone- releasing intrauterine system; bilateral occlusion of the Fallopian tubes; vasectomized partner; sexual abstinence

You may not qualify if…
