What should you know about draining fluid from lungs pneumonia?

Pneumonia inflames lung tissue and can cause fluid to gather in the space between the lung and chest wall. This is called a pleural effusion. Some collections are small and improve as the infection is treated. A larger collection, thick infected fluid, or fluid that limits lung expansion may need a procedure.

A clinician may use an examination, chest imaging and a sample of the fluid to decide whether drainage is appropriate. The procedure may involve a needle or a small tube placed through the chest wall, with local anaesthetic and monitoring.

Follow the prescribed pneumonia treatment and attend the review arranged after imaging or drainage. Keep the dressing around a drain clean and dry according to the clinical team’s instructions. Rest, drink fluids if you can, and record changes in breathing, temperature, chest pain or sputum.

Cough, fever, chills and coughing up phlegm can accompany pneumonia. COVID-19 and Influenza can also cause respiratory symptoms, so testing or examination may be advised.

Get emergency help for severe breathlessness, blue or grey lips, confusion, fainting, or rapidly worsening chest pain. Seek prompt medical review for increasing fever, new weakness, drainage that becomes heavily bloody or foul-smelling, or redness spreading around a drain site. Sepsis is a medical emergency and can include sudden deterioration, confusion or very fast breathing.

Where is the fluid, and how is its size being assessed? Does it look infected? Would antibiotics alone be suitable, or is drainage recommended? How should the drain site be cared for, and when will it be removed?
