Thoracostomy tubes are routinely used to drain the pleural space of fluid and gas to optimize pulmonary mechanics. Clinicians frequently postpone removal of thoracostomy tubes if the drainage from the tube exceeds a specific volume threshold for the prior 24 hours. However, there is substantial variability in the drainage volume threshold that different clinicians use, and no threshold has been established as clearly superior to any other. Removing tubes independently of the drainage volume may result in a greater risk of pleural effusion or pneumothorax requiring an invasive drainage procedure. However, removing tubes independently of the drainage volume might also expedite recovery by allowing earlier removal of the tube, thus diminishing pain and increasing patient mobility.
