Current diagnostic methods and medical management of thoracic empyemas
1Intensive Care Unit, Cardiopulmonary Services, Androscoggin Valley Hospital, Berlin, New Hampshire, USA.
Abstract:
Infections can invade the normally sterile pleural space leading to the development of parapneumonia effusions or empyemas. Pneumonia, thoracic surgery, and trauma, together, are responsible for most cases of empyemas. Pneumococci and staphylococci remain the predominant etiologic organisms. In addition, gram-negative aerobic bacteria and anaerobes are emerging as important pathogens. Most parapneumonic pleural effusions, regardless of their underlying etiology and bacteriology, evolve through definable stages. For each stage of the disease, specific therapeutic measures, either medical or surgical, are available.
Insights
Infections can cause parapneumonic effusions and empyemas, often stemming from pneumonia, surgery, or trauma. Treatment strategies vary based on the disease stage and identified pathogens.
Area of Science:
- Pulmonology
- Infectious Diseases
- Thoracic Surgery
Background:
- Infections can compromise the normally sterile pleural space, leading to parapneumonic effusions or empyemas.
- Pneumonia, thoracic surgery, and trauma are primary causes of empyemas.
- Predominant pathogens include Pneumococci and Staphylococci, with emerging roles for gram-negative aerobic bacteria and anaerobes.
Purpose of the Study:
- To describe the stages of parapneumonic pleural effusions and empyemas.
- To outline available therapeutic measures for each stage.
Main Methods:
- Review of existing literature on parapneumonic effusions and empyemas.
- Analysis of etiological factors and common pathogens.
- Description of disease progression through distinct stages.
Main Results:
- Parapneumonic effusions and empyemas result from infections invading the pleural space.
- Common causes include pneumonia, thoracic surgery, and trauma.
- Key pathogens are Streptococcus pneumoniae, Staphylococcus aureus, gram-negative bacteria, and anaerobes.
- Pleural effusions progress through identifiable stages.
Conclusions:
- Understanding the stages of parapneumonic effusions and empyemas is crucial for effective management.
- Both medical and surgical therapeutic options exist for each stage of the disease.
- Identifying causative organisms aids in targeted treatment strategies.
