About Empyema
The pathophysiologic causes of empyema include bacterial pneumonia, parapneumonic effusion, bronchogenic carcinoma, esophageal rupture, chest trauma, infectious mediastinitis, intraabdominal infections, cervical or thoracic spine infections, and post-surgical infections. The infection spreads to the pleural space due to increased permeability of the inflamed pleura.
Non-modifiable risk factors for empyema include:
- Age: Being older than 70 increases the risk.
- Recent hospital stay: Having a recent hospital stay is a risk factor.
- Chest surgery or trauma: Previous chest surgery or trauma increases the risk.
- Diabetes: Having diabetes is associated with a higher risk.
- Heart disease: People with heart disease are more likely to develop Empyema.
- Previous cancer: A history of cancer increases the risk.
- Chronic obstructive pulmonary disorder (COPD): COPD is a risk factor.
- Lung disease: Having a pre-existing lung disease increases the risk.
Modifiable risk factors for empyema include:
- Poor dietary habits: Maintaining a healthy diet is recommended.
- Low physical activity: Being physically inactive increases the risk.
- Lifestyle factors: Excessive alcohol intake and tobacco use can contribute to the development of Empyema.
Remember, these risk factors are not exhaustive, and individual cases may vary. It's essential to consult with your healthcare professional for personalized advice.
The most common early symptoms of empyema include:
- Chest pain, which worsens when you breathe in deeply (pleurisy)
- Dry cough
- Excessive sweating, especially night sweats
- Fever and chills
- General discomfort, uneasiness, or ill feeling (malaise)
- Shortness of breath
- Unintentional weight loss
As empyema progresses or reaches higher severity, other symptoms may occur, such as:
- Pus in mucus
- Difficulty breathing
- A crackling sound in the chest
- Decreased breathing sounds
- A dull sound when tapping the chest
In later stages of empyema, it can be seen on an X-ray as a buildup of fluid in the affected area. Without treatment, empyema can progress through three stages:
- Simple empyema (exudative phase): Extra fluid builds up in the pleural cavity, which can become infected and contain pus.
- Complicated empyema (fibrinopurulent phase): The fluid thickens and forms pockets in the pleural cavity.
- Frank empyema (organizing phase): The infected fluid causes scarring on the inner layers of the lungs, leading to difficulty breathing.
Remember to consult with your healthcare professional for a proper diagnosis and treatment plan.
To diagnose Empyema, the following examinations, tests, and procedures are commonly performed:
- Clinical Presentation: Doctors assess the patient's symptoms, such as pleuritic chest pain, cough, fever, chills, weight loss, anorexia, dyspnea, and night sweats.
- Imaging Studies: Chest X-ray or computed tomography (CT) scan can help visualize the presence of fluid or infection in the pleural space.
- Pleural Fluid Analysis: A sample of pleural fluid is obtained through thoracentesis and analyzed for infection-causing microorganisms.
- Gram Staining: This technique helps identify the type of bacteria present in the pleural fluid.
- Gene Expert and AFB Smear Examination: These tests specifically check for Mycobacterium tuberculosis if it is suspected.
- Culture and Sensitivity Testing: The collected fluid is cultured to identify the specific bacteria causing the infection and determine their sensitivity to antibiotics.
To determine the stage or severity of Empyema, additional examinations, tests, and procedures may be performed:
- Pleural Ultrasound (US): This imaging technique helps visualize the amount and location of fluid in the pleural space.
- Conventional Chest X-ray or CT Scan: These imaging studies can provide a more detailed assessment of the extent of infection and any complications like septations or loculations.
- Serum Examinations: Detailed blood tests are conducted to evaluate the patient's overall health status and assess for any signs of systemic infection.
- Surgical Intervention: In some cases, surgical procedures like Video-Assisted Thoracoscopic Surgery (VATS) may be necessary to drain persistent fluid, remove any debris or infected tissue, and assess the stage of Empyema.
Remember that these examinations, tests, and procedures should be performed under the guidance of a healthcare professional.
The goals of treatment for Empyema are as follows:
- Control infection: The main goal is to eliminate the infection by using appropriate antibiotics. Antibiotics are crucial in treating empyema and should be tailored to target the specific bacteria causing the infection. It is important to find the right antibiotic to effectively control the infection.
- Drainage of infected fluid: Draining the fluid is essential to prevent the progression of Empyema. A procedure called tube thoracostomy is performed, where a tube is inserted into the chest cavity to remove the infected fluid from the pleural space. This helps in reducing the infection and keeping it under control.
- Improve lung expansion: Surgical intervention may be necessary for advanced cases of Empyema. Decortication, a surgical procedure, involves removing pus pockets and fibrous tissue from the pleural space, allowing the lungs to expand properly. This helps improve lung function and aids in recovery.
It is important to note that medication types, therapies, therapeutic procedures, and health behavior changes can vary depending on the individual case and severity of empyema. It is recommended to consult with a healthcare professional for personalized treatment recommendations.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
