Mortality & Morbidity in Pleural Effusion
Mortality & Morbidity in Pleural Effusion
- Less in
- Most effusions caused by viral and mycoplasmal infections spontaneously resolve.
Mortality & Morbidity in Pleural Effusion
- More in
- Empyema causes significant acute morbidity.
- Death from empyema in previously healthy children in the developed world is uncommon.
- The mortality rate is higher for children < 2 years.

- Intro
TTT of Pleural Effusion
- IV Antibiotics
Indications of IV Antibiotics in Pleural Effusion
- Indicated in all cases of parapneumonic effusion
Duration of IV Antibiotics in Pleural Effusion
- Continue for at least several days after fever & fluid drainage subside.
- Orally administered antibiotics should be given for an additional 1-2 weeks.
TTT of Pleural Effusion
- Chest tube Draining
Chets Tube Drainage in Pleural Effusion
- Indications
- Indicated in complicated effusion
Chets Tube Drainage in Pleural Effusion
- Characters of Response
Chets Tube Drainage in Pleural Effusion
- Role of Chest X-Ray
- CXR alone is not a good indicator of response because pleural opacification persists for weeks after infection & fluid have cleared.
