Pneumothorax Flashcards
Causes of primary pneumothorax
Young patients without any underlying disease.
Often tall and thin
Causes of secondary pneumothorax
COPD
Asthma
Cystic fibrosis
Lung cancer
PCP
Connective tissue disease such as marfans
What is a tension pneumothorax?
Severe pneumothorax resulting in the displacement of mediastinal structures that may result in severe respiratory distress and haemodynamic collapse
Clinical features on examination
Hyperresonant
reduced breathsounds
reduced lung expansion
tachypnoea
tachycardia
What are high risk characteristics of pneumothorax that mean a drain is required?
Tension
Hypoxia
Bilaterla
Underlying lung disease
>50 with smoking Hx
Haemothorax
What features mean a pneumothorax is safe to drain without further imaging
2cm laterally or apically on CXR
Is not safe to intervene with pneumothorax imagining on CXR alone what imaging can be done?
CT imaging
When can a chest drain be removed?
When pneumothorax resolved (stopped bubbling spontaneously or resolution on CXR)
If no red flag features what options are available for management of pneumothorax?
Procedure avoidance
ambulatory device
needle aspiration
If a pneumothorax is asymptomatic what is the preferred management?
Conservative care
reviewed as OP in 2-4 days
Secondary pneumothoraxs should be observed as inpatient
When should needle aspiration be done?
Symptomatic
no red flag
patient preference for symptoms relief
Management of persistent pneumothorax/ pleurobronchogenic fistula
VATS should be considered for mechanical/ chemical pleurodesis +/- bullectomy
Discharge advice for pneumothorax
smoking cessation
Fly 2 weeks post drainage if no resdual air
