[Advantages of a new thoracic drainage unit with double sealing]

The paper deals with the application of a new 'Four-Compartment Drainage System' with double-sealing in 20 patients having lung parenchyma resections, explorative thoracotomies, and pneumothorax. This drainage system has an advantage over conventional intercostal drainage in as much as it prevents tension pneumothorax in leakage of the lung and suction failure. The closed system avoids bacterial contamination of the pleural space.
