In patients with established malignancy and pleural effusion, when malignant cells have not or cannot be detected in the pleural fluid or tissue, Sahn et al. Malignant pleural effusion is confirmed by the presence of malignant cells in pleural fluid or tissue. This was similar to what was found earlier by Thomas et al. , also found that neoplastic diseases were the commonest cause of pleural effusions. showed that the flutter drainage system is a safe and feasible system when pleural drainage is needed in the treatment of pneumothoraces and pleural effusions.Pleural effusion is an abnormal accumulation of fluid in the pleural space and neoplastic diseases accounts for 13% to 40% of all the pleural effusions worldwide and account for 70% of all massive effusions. The one-way valve system provides better mobility of patients because clamping is unnecessary during transportation and the valve keeps working regardless of its position/level. The flutter valve drainage bag is a ‘no water’ ambulatory system which incorporates a one-way valve and can be used both in hospital and outpatient drainage of pleural collections. , showed that bags with integral non-return valves could be used for chest drainage. ![]() In 1968, Henry Heimlich idealized a device (The Heimlich valve) to replace under water-seal drainage systems and this is the concept of the flutter valve drainage bag as popularized by Portex USA. The frequent clamping during transport can cause pulmonary collapse, formation of clots and can result in worsening of an existing pneumothorax. Placement of underwater seal below the chest wall often causes disconnection of the connectors and it also puts tension on the anchoring stitch, resulting in increased risk of chest tube mishaps. Thoracic drainage systems are designed to remove air and fluid from the pleural space and the underwater seal drainage system in its present form was first described by Kenyon in 1916 and since then has been the standard form of chest drainage. ![]()
