Traumatic wet lung is a common lung parenchymal injury, mostly due to swift blunt injury, with the main pathological changes being alveolar and capillary injury with interstitial and intra-alveolar blood exudation, and interstitial pulmonary edema, which can lead to ventilation and ventilatory dysfunction. The pathological changes develop progressively 12-24 hours after the injury, and the clinical manifestations vary widely. In mild cases, there is only chest pain, dyspnea, cough, cyanosis, bloody foamy sputum, tachycardia, and decreased blood pressure, etc. The disease can lead to pulmonary atelectasis and pneumonia, and in severe cases, it can be life-threatening. General examination of blood gas analysis, CT of the chest, treatment to maintain respiratory and circulatory function, appropriate treatment of combined injuries, with active treatment can improve the symptoms, the general prognosis is good.
