Does size matter? A prospective analysis of 28-32 versus 36-40 French chest tube size in trauma.

Background: The optimal chest tube size for the drainage of traumatic hemothoraces and pneumothoraces is unknown. The purpose of this study was to compare the efficacy of small versus large chest tubes for use in thoracic trauma. Our hypothesis was that (1) there would be no difference in clinically relevant outcomes including retained hemothoraces, the need for additional tube insertion, and invasive procedures and (2) there would be an increase in pain with the insertion of large versus small tubes.
