Treatment for fluid around the lungs involves treatment of the underlying medical condition, such as using diuretics for congestive heart failure and taking antibiotics for pneumonia, according to WebMD. Other treatments depend on the severity of the condition and include draining the fluid, pleurodesis and surgery, reports Healthline.
When the fluid around the lungs has affected a large area, causing infection and inflammation, then drainage of the fluid is necessary to improve the symptoms and avoid the risk of complications, explains WebMD. Procedures that help fluid drain include thoracentesis, tube thoracotomy, installing a pleural drain and pleural decortication. Most doctors prescribe pain-relief medication to help after the procedures, says Healthline.
