What is a pneumothorax (new-mo-thor-ax)?

This means the lung has collapsed and there is air between the lung and the chest wall.  Normally this space is very small and only contains some lubricating fluid, but lung damage means air leaks into the space as well.

They can occur following injury or spontaneously.  Spontaneous pneumothoraces are more common in men, smokers and those with underlying lung disease.

Symptoms include chest pain, shortness of breath and a dry cough.

What is the treatment?

This depends on several factors:

• The cause of the pneumothorax (spontaneous or traumatic)

• Whether or not you have underlying lung disease

• What symptoms you have

• How big the pneumothorax is.

Generally speaking, if your pneumothorax was caused by trauma or is very large or making you short of breath then we will need to remove it either by sucking the air out through a needle or by placing a tube called a chest drain.  In the latter case you will need to stay in hospital but you may be able to go home if only a needle is required (aspiration of the pneumothorax).

If it is very small and isn’t causing breathing difficulties, then it is very likely to resolve without treatment.

Whether or not it is drained, it is important that you return to clinic in 7-10 days (you will be given an appointment before leaving the Emergency Department).

Can I take painkillers?

• Paracetamol is useful to ease pain. It is best to take it regularly for a few days or so, rather than every now and then. An adult dose is two 500 mg tablets, four times a day. A doctor may pre-scribe additional painkillers such as codeine if the pain is more severe.  If you are prescribed a combination of paracetamol and codeine (e.g., cocodamol or codydramol) then it is important not to take additional paracetamol as you will accidentally overdose

• Anti-inflammatory medication can be used with paracetamol or as an alternative. There are many types and brands. They relieve pain and reduce inflammation and swelling (often the cause of the pain). You can buy ibuprofen at pharmacies or supermarkets without a prescription. The dose varies depending on your age and other medical problems. Side-effects sometimes occur with anti-inflammatory painkillers. Ask your doctor or pharmacist for advice regarding them

If pain is not controlled by these simple painkillers, do not exceed the recommended dose but see your general practitioner to discuss the possibility of stronger painkillers.
