Study summary

Researchers will compare 3 standard of care methods of pleural fluid drainage during therapeutic thoracentesis. Patients are randomized to manual aspiration, vacuum bottle drainage or wall suction methods. Primary outcome is procedural time with secondary outcomes of pain and dyspnea scores.

Study arms

  • Active comparator
    Manual aspiration

    pleural fluid is drained using a standard thoracentesis kit and via a syringe and three-way stopcock

    Procedure: Manual aspiration

  • Active comparator
    Wall suction

    pleural fluid is drained using a standard thoracentesis kit and by attaching tubing to wall suctioning set at -50 mmHg continuously

    Procedure: Wall suction

  • Active comparator
    Vacuum bottle drainage

    pleural fluid is drained using a standard thoracentesis kit and tubing that attaches to a glass vacuum container

    Procedure: Vacuum bottle drainage

What researchers measure

Primary outcomes

  1. Procedural time to 500mL

    Time to pleural fluid drainage from initiation of therapeutic drainage to 500mL

    Time frame: Through study completion, an average of 24 hours

  2. Procedural time to 750mL

    Time to pleural fluid drainage from initiation of therapeutic drainage to 750mL

    Time frame: Through study completion, an average of 24 hours

  3. Procedural time to 1L

    Time to pleural fluid drainage from initiation of therapeutic drainage to 1L

    Time frame: Through study completion, an average of 24 hours

  4. Pain and dyspnea scores- Baseline

    Patients will be asked to indicate their pain and dyspnea level verbally using the Modified Borg Scale for Dyspnea and Numerical Ratings Scale (0-10, with 10 being highest level of pain)

    Time frame: Immediately prior to starting the thoracentesis

  5. Pain and dyspnea scores- Cath

    Patients will be asked to indicate their pain and dyspnea level verbally using the Modified Borg Scale for Dyspnea and Numerical Ratings Scale (0-10, with 10 being highest level of pain)

    Time frame: Through study completion, an average of 24 hours

  6. Pain and dyspnea scores- Post-fluid

    Patients will be asked to indicate their pain and dyspnea level verbally using the Modified Borg Scale for Dyspnea and Numerical Ratings Scale (0-10, with 10 being highest level of pain)

    Time frame: Through study completion, an average of 24 hours

  7. Pain and dyspnea scores- Post-cath

    Patients will be asked to indicate their pain and dyspnea level verbally using the Modified Borg Scale for Dyspnea and Numerical Ratings Scale (0-10, with 10 being highest level of pain)

    Time frame: Immediately after removing the thoracentesis catheter

  8. Pain and dyspnea scores- 5m post

    Patients will be asked to indicate their pain and dyspnea level verbally using the Modified Borg Scale for Dyspnea and Numerical Ratings Scale (0-10, with 10 being highest level of pain)

    Time frame: 5 minutes post-procedure

  9. Pain and dyspnea scores- 24h post

    Patients will be asked to indicate their pain and dyspnea level verbally using the Modified Borg Scale for Dyspnea and Numerical Ratings Scale (0-10, with 10 being highest level of pain)

    Time frame: 24 hours post-procedure
