Needle Aspiration of Pneumothorax

  • Use thoracentesis or "pig-tail" kit, if available
  • Place in 2nd IC space in midclavicular line or 4th/5th IC space in anterior axillary line
  • Withdraw air with syringe until no more can be aspirated
    • Assume a persistent air leak (failure) if no resistance after 4 liters of air has been aspirated AND the lung has not expanded
  • Once no further air can be aspirated:
    • Option 1
      • Place closed stopcock and secure catheter to the chest wall
      • Obtain CXR four hours later
      • If adequate lung expansion has occurred, remove catheter
      • Following another two hours of observation, obtain another CXR
      • If the lung remains expanded, may discharge patient
    • Option 2
      • Leave catheter in place
      • Attached a Heimlich (one-way) valve
      • May discharge with follow-up within two days

Reexpansion pulmonary edema

  • Incidence may be as low as 1% or as high as 14%[1]
    • Typically progresses over 2 days immediately after thoracentesis
    • Radiographic opacities in previously collapse lung
    • After 2 days, subsequent rapid improvement
  • To avoid this complication, consider using a small bore chest tube
  • Other strategies include applying water seal only or attaching only a Heimlich valve without suction
  • If development occurs, treatment is supportive as is with other forms of noncardiogenic pulmonary edema
    • If a patient requires intubation, positive pressure ventilation improves symptoms after 24-48 hours
  • Risk factors are poorly understood but may include:
    • PTX > 30% in size
    • PTX symptoms for prolonged time, > 3 days
