Abstract:
Parapneumonic effusions are seen in up to 57% of patients with pneumonia. The majority of these effusions are noninfected and resolve with standard antibiotic treatment for the associated pneumonia. However, parapneumonic effusions in a minority of cases become infected and require prompt chest tube drainage and occasionally thoracic surgery. Patients may present in a variety of ways from florid sepsis to weight loss and anorexia; such diversity mandates a high index of suspicion among physicians. The role of the combination of intrapleural deoxyribonuclease (DNase) and tissue plasminogen activator (t-PA) to aid fluid drainage shows promise but needs further assessment in large trials with surgery and mortality as primary end points.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
Clinical Manifestations:
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
