PLEURAL EFFUSION
A pleural effusion is a buildup of fluid between the layers of tissue that line the lungs and chest cavity.
The body produces pleural fluid in small amounts to lubricate the surfaces of the pleura. This is the thin tissue that lines the chest cavity and surrounds the lungs. Pleural effusion is an abnormal, excessive collection of this fluid.
There are two types of pleural effusion:
Transudative pleural effusion is caused by fluid leaking into the pleural space. This is from increased pressure in the blood vessels or a low blood protein count. Heart failure is the most common cause.
Exudative effusion is caused by blocked blood vessels or lymph vessels, inflammation, infection, lung injury, and tumors.
Risk factors of pleural effusion may include:
Smoking and drinking alcohol
Any previous complaint of high blood pressure
History of any contact with asbestos
Symptoms can include any of the following:
Chest pain, usually a sharp pain that is worse with cough or deep breaths
Cough
Fever and chills
Hiccups
Rapid breathing
Shortness of breath
Sometimes there are no symptoms.
The goal of treatment is to:
•Remove the fluid
•Prevent fluid from building up again
•Determine and treat the cause of the fluid buildup
Removing the fluid (thoracentesis) may be done if there is a lot of fluid and it is causing chest pressure, shortness of breath, or a low oxygen level. Removing the fluid allows the lung to expand, making breathing easier.
The cause of the fluid buildup must also be treated:
•If it is due to heart failure, you may receive diuretics (water pills) and other medicines to treat heart failure.
•If it is due to an infection, antibiotics will be given.
•In people with cancer or infection, the effusion is often treated by using a chest tube to drain the fluid and treating its cause.
Some of treatment techniques physiotherapy provides include;
Secretion clearance:
•Effective / productive coughing techniques.
•Postural drainage in sitting and lying.
•Manual assistance, including percussion, vibrations and shaking.
Breathing technique retraining:
•Controlling respiratory rate
•Diaphragmatic breathing
•Controlling / reducing breath volume
•Relaxation
