Summary

Fever and systemic inflammation after thoracoscopic pleurodesis are caused by talc poudrage, not the thoracoscopy procedure itself. This finding helps differentiate side effects in patients undergoing pleurodesis.

Area of Science:

  • Pulmonology
  • Surgical Complications
  • Inflammation Research

Background:

  • Fever is a reported side effect of talc poudrage in thoracoscopic pleurodesis.
  • Thoracoscopy, an interventional procedure, can independently trigger a systemic inflammatory response.
  • Distinguishing the cause of inflammation is crucial for patient management.

Purpose of the Study:

  • To determine if fever and systemic inflammation following thoracoscopic pleurodesis are attributable to talc poudrage or the thoracoscopy procedure.
  • To differentiate the inflammatory effects of talc administration versus the surgical intervention.

Main Methods:

  • Prospective study comparing two groups: thoracoscopic talc poudrage (18 patients) and diagnostic thoracoscopy alone (17 patients).
  • Monitoring of body temperature, white blood cell (WBC) count, and C-reactive protein (CRP) levels at baseline, 24, and 48 hours post-procedure.

  • Exclusion of anti-inflammatory medication use and 3-month follow-up for all participants.

    • Main Results:

    • Significant temperature increase observed in the talc poudrage group (p = 0.005), particularly at 9, 12, and 24 hours.
    • Elevated WBC count (p = 0.004), neutrophil percentage (p = 0.03), and CRP levels (p < 0.0001) in the talc poudrage group.
    • Significant decrease in lymphocytes (p = 0.01) noted in the talc poudrage group; mild side effects like pain and subcutaneous emphysema were reported, with no severe complications.

    Conclusions:

    • Fever and systemic inflammatory responses observed post-thoracoscopic pleurodesis are primarily caused by talc poudrage.
    • Thoracoscopy alone does not appear to induce significant systemic inflammation or fever.
    • These findings clarify the etiology of post-procedural inflammatory markers, aiding in clinical interpretation.
