How long can lung contusion cure?
summary
Pulmonary contusion is a common lung parenchymal injury, which is mostly caused by rapid blunt injury, such as car accident, impact, extrusion and fall. The incidence of blunt chest injury is about 30% - 75%, but it is often ignored or missed because of lack of understanding, insensitivity of examination techniques or being covered by other chest injuries. Now let's share about how long can pulmonary contusion be cured? The knowledge of.
How long can lung contusion cure?
First, mild pulmonary contusion should also be treated. Severe pulmonary contusion is the most common cause of acute respiratory failure after chest injury. The treatment is to maintain respiratory and circulatory function and properly deal with the combined injury.
Second, flail chest often has different degrees of pulmonary contusion, and the pathophysiological changes largely depend on pulmonary contusion. When the aura of acute respiratory failure occurs, mechanical ventilation should be given in time.
Third, the application of corticosteroids is not emphasized as before. For patients with hypovolemic shock, blood volume should be replenished in time, the ratio of crystal and colloid should be matched reasonably, and the normal colloid osmotic pressure and total osmotic pressure should be maintained. In the future, the negative liquid balance should be maintained, with a daily volume of 1600-1800 ml.
matters needing attention
After treatment, it usually starts to absorb 2-3 days after injury, and it takes more than 2-3 weeks for complete absorption. In recent years, through a series of CT examination, a new pathological view of pulmonary contusion has been put forward. The contusion shown on X-ray plain film is the laceration of lung parenchyma and a piece of alveolar hematocele around the laceration on CT film, but no pulmonary interstitial injury.
