Introduction:
Pleural effusions are common and carry substantial morbidity, mortality, and healthcare costs. Management can be particularly challenging when effusions arising from systemic diseases such as congestive heart failure (CHF) or cirrhosis are refractory to medical management or when the effusion occurs due to disruption of the thoracic lymphatic system, as in chylothorax.
Areas Covered:
This review examines current approaches to the diagnosis and management of congestive heart failure-related effusions, hepatic hydrothorax, and chylothorax. In addition, we seek to identify areas for future investigation across all three conditions, particularly the evidence guiding invasive management such as thoracentesis, indwelling pleural catheters, and pleurodesis. To accomplish this, we conducted a literature search in PubMed between 1 August 2026 - 13 August 2026, using a combination of free-text keywords related to the listed effusions.
Expert Opinion:
If medical/conservative management of complicated pleural effusion fails, there are multiple treatment options for each of the discussed effusions, but no clear-cut superior option as the current literature is limited. Future studies will require multi-center and multi-disciplinary collaboration but will likely reveal that treatment should be based on an individual level, accounting for local expertise and incorporating patients' preferences.

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:
Pleural Effusion I: Introduction
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

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.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
