    Thoracentesis can cause temporary hypoxemia (low oxygen levels), which resolves within 24 hours. This condition is linked to the amount of fluid removed and can be reversed with oxygen therapy.

    Area of Science:

    • Pulmonary Medicine
    • Critical Care Medicine

    Background:

    • Thoracentesis is a common procedure for pleural fluid removal.
    • Potential complications include hypoxemia, requiring further investigation.

    Purpose of the Study:

    • To investigate the incidence and characteristics of hypoxemia following thoracentesis.
    • To identify factors influencing post-thoracentesis hypoxemia and its management.

    Main Methods:

    • Observational study involving patients undergoing thoracentesis.
    • Monitoring of oxygen saturation, pH, PaCO2, and bicarbonate levels post-procedure.
    • Correlation analysis between fluid volume removed and hypoxemia severity.

    Main Results:

    • Hypoxemia occurred in 15 patients at 20 minutes and 2 hours post-thoracentesis.

  • Hypoxemia resolved within 24 hours in all affected patients.
  • The severity of hypoxemia directly correlated with the volume of pleural fluid removed.
  • Oxygen therapy effectively reversed the observed hypoxemia.

    • Conclusions:

    • Transient hypoxemia is a potential complication of thoracentesis.
    • Pulmonary edema is a likely contributing factor to post-procedure hypoxemia.
    • Fluid removal volume is a key determinant of hypoxemia severity.
