title: [Is the routine chest radiography following thoracentesis necessary?].
abstract: OBJECTIVE
  To assess the routine indication of chest roentgenogram after thoracentesis in function of iatrogenic pneumothorax causation, following a procedure protocol.
  
  
  METHODS
  Prospective study of 104 consecutive thoracentesis procedures performed in 76 patients. The procedure was protocolized and after each thoracentesis a chest roentgenogram was obtained within 6 hours after the procedure. The attending physician completed a questionnaire relative to patients data characteristics of the pleural effusion.
  
  
  RESULTS
  Two pneumothorax were noted following thoracentesis (2%) which did not require pleural drainage. These pneumothorax occurred in patients with parapneumonic pleural effusions.
  
  
  CONCLUSIONS
  The routine practice of chest roentgenogram after thoracentesis does not seem to be warranted and should be individualized. The performance of thoracentesis by physicians in training period, with procedure protocolization, minimizes the risk of pneumothorax.
