This procedure involves insertion of a tube into the chest cavity to drain fluid or blood or air from the chest and thereby allow the lung to expand. Many a times, it is a lifesaving procedure and a basic skill that every doctor should be able to perform. It is performed under Local Anaesthesia and needs a clean environment, which could be a ward or an operation theatre. The tube is then connected to a bottle with a water column which is kept on the floor. It could be an Out-Patient procedure and the patient can be sent home with the chest tube and the draining bottle. This tube is removed when the drainage of fluid or air has stopped and the lung is fully expanded. This removal takes few minutes and the patient can go home afterwards.
