Near Hanging Induced Negative Pressure Pulmonary Edema

Negative pressure pulmonary edema (NPPE) is a rare condition with a high mortality rate. This condition causes acute respiratory failure occurring when sudden, forceful inspiration is against an obstructed airway. Near-hanging is referred to patients having survived a hanging injury. During hanging, the entire neck structure is compressed. This causes sudden airway obstruction, and may develop into acute respiratory failure from suddenly increase intrathoracic pressure. To our knowledge there have not often been reported incidences of negative pressure pulmonary edema after a near hanging condition. Herein, we report a case of negative pressure pulmonary edema after hanging condition.
