Q

Primary pneumothorax mx?

A
  1. If rim of air is < 2cm and the pt is not SOB then discharge considered
  2. Otherwise aspiration should be attempted
  3. If this fails (defined as > 2 cm or still short of breath) then a chest drain should be inserted
  4. Patients should be advised to avoid smoking to reduce the risk of further episodes - the lifetime risk of developing a pneumothorax in healthy smoking men is around 10% compared with around 0.1% in non-smoking men

  2. Otherwise aspiration should be attempted if the rim of air is between 1-2cm. If aspiration fails (i.e. pneumothorax is still greater then 1cm) a chest drain should be inserted. 3. All patients should be admitted for at least 24 hours
  3. If the pneumothorax is less the 1cm then the BTS guidelines suggest giving oxygen and admitting for 24 hours
