Document Summary
Ww1 & ww2: chest wounds treated with needle aspiration and wound thoracotomy/cutting off pieces of the lungs (56% mortality rate) Korean war 1950s: repeated pleural aspiration used with a reported 85. 6% success in reexpansion with 80% of soldiers returning to duty within 90 days. Emergency war surgery nato handbook (1958): it is recommended empty the pleural space as completely as possible. 1963: dr. maloney advocated a 30f foley catheter and 2 bottle suction system, using closed water seal drainage and 20 mmhg negative pressure is applied to the catheter. Inspiratory intrapleural pressure: -8 cm of h2o (below atmospheric pressure) Excitatory intrapleural pressure: -4 cm of h2o. These negative pressure keep a vacuum within the pleural space that keeps the two pleura together and allows the lung to expand and contract. Pneumothorax: most common cause of cardiopulmonary derangements when compared with other thoracic injuries heart can be punched over towards the left side.
