Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Number of treatment failure

    Treatment failure, defined as a composite outcome that includes death, the need for thoracic surgery, or additional intrapleural enzyme therapy. This criterion will be assessed at 30 days.

    at 30 days

Secondary Outcomes (11)

  • Volume of pleural fluid drained from randomization

    at day 3

  • Incidence of adverse events

    at 90 days

  • Intra-hospital mortality

    at 30 days

  • Intra-hospital mortality

    at 90 days

  • Rate of thoracic surgery

    at 30 days

  • +6 more secondary outcomes

Study Arms (2)

intrapleural irrigation

EXPERIMENTAL

Experimental group: 500 mL bags of 0.9% sodium chloride will be administered into the thoracic cavity via the chest tube using a three way tap and gravity (no infusion pump or pressure). The infusion is followed by free drainage with thoracic suction (up to -20 cmH2O). This process will occur twices daily for a total of 6 irrigations.

Drug: intrapleural irrigation

standard care

ACTIVE COMPARATOR

Control group: Standard care includes pleural drainage with 20 mL 0.9% sodium chloride flushes administered twice daily for 3 days to maintain tube patency. Thoracic suction (up to -20 cmH2O) will be applied to chest tubes.

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

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:

  • Tuberculous pleural effusions;
  • Previous treatment with intrapleural fibrinolytic agents (urokinase, streptokinase, alteplase, or DNase) or intrapleural saline lavage;
  • Previous thoracic surgery for pleural infection;
  • Contraindications to auxiliary treatments, to fibrinolysis or surgery as well as to procedures such as drainage and lavage;
  • Pregnancy or lactation;
  • Expected survival of less than 3 months;
  • Thoracic drainage since more than 24h;
  • Patient deprived of liberty by administrative or judicial decision or placed under judicial protection (guardianship or supervision);
  • Inability to give informed written consent;
  • Participation in another clinical trial;
  • Patient being a relative of the investigator or any member of the team directly involved in the study, including assistant physicians, pharmacists, nurses, and coordinators
