(Sucking chest wound)
An open pneumothorax is a pneumothorax with an unsealed opening in the chest wall; if the opening is sufficiently large, the mechanics of breathing is impaired.
Spontaneous Pneumothoray is discussed elsewhere (pneumothorax).
An open pneumothorax is a pneumothorax with an unsealed opening in the chest wall; if the opening is sufficiently large, the mechanics of breathing is impaired. Spontaneous Pneumothoray is discussed elsewhere (pneumothorax). Some patients ((pneumothorax traumatic)) with traumatic pneumothorax have an unsealed opening in the chest wall. When patients breathe with an open pneumothorax, the negative pressure generated by inspiration effected in the chest area that air passes through the trachea into the lungs, and at the same time in the intrapleural space through the chest wall defect. There is little airflow through small chest wall defects and few side effects. However, if the opening in the chest wall is sufficiently large (when the defect is greater than or about two-thirds the diameter of the trachea), more air passes through the chest wall defect and through the trachea into the lungs. Larger defects can eliminate breathing on the affected side. Inability to ventilate the lungs causing shortness of breath and respiratory arrest. In conscious patient’s chest wound is painful and patients have shortness of breath and other manifestations of pneumothorax (pneumothorax (traumatic): symptoms and complaints). The air that enters the wound, making a sucking sound characteristic generally. Diagnosis Clinical Investigation The diagnosis is clinical and requires the study of the entire surface of the chest wall. Therapy partially occlusive dressing followed by thoracostomy Immediate treatment is to cover the wound with a sterile rectangular occlusive dressing, which is securely closed with tape on only 3 pages. Thus, the dressing prevents atmospheric air during inspiration gets into the chest wall, but allows intrapleural air to escape during exhalation. Thoracostomy should be performed when the patient is stabilized. When the wound later surgical treatment may be necessary.
