Inspiratory crackles in both lungs

Introduction

Introduction The alveolar-capillary block syndrome is a group of symptoms in which the interstitial wall of the alveolar-capillary constituting the gas diffusion surface is degenerated and the oxygen diffusion ability is reduced. Mostly caused by diseases of the lungs. The clinical manifestations are progressive dyspnea, followed by varying degrees of cyanosis, and shallow and rapid breathing. After a long illness, clubbing (toe, cough, a small amount of cough, fever, weight loss, etc. may occur in the late stage of right heart failure. Typical signs are mainly inhalation pops and clubbing of both lungs.

Cause

Cause

There are many causes of alveolar-capillary gas diffusion disorder, such as pulmonary fibrosis caused by systemic lupus erythematosus and rheumatoid arthritis, lung damage caused by scleroderma, exogenous alveolitis, lung Sarcoidosis, idiopathic pulmonary interstitial fibrosis, obstructive bronchiolitis with organizing pneumonia, various forms of intrapulmonary granulomatous disease, alveolar cell carcinoma, multiple pulmonary microthrombus, pulmonary hemorrhage Sedimentosis, alveolar proteinosis, pulmonary interstitial fibrosis caused by various drugs, are all within the scope of this syndrome.

In addition to the clinical manifestations of the primary disease, the following common characteristics: the incidence of the disease is slower than the hidden. Progressive breathing difficulties, followed by varying degrees of cyanosis, breathing shallow and fast. After a long illness, clubbing (toe, cough, a small amount of cough, fever, weight loss, etc. may occur in the late stage of right heart failure. Typical signs are mainly inhalation pops and clubbing of both lungs.

Complications: Late concurrent right heart failure.

Laboratory examination: Mainly restrictive ventilation disorders, and diffuse obstacles. There was no obvious obstructive ventilatory disorder and uneven blood flow.

Other ancillary examinations: Chest X-ray examination of diffuse spotted, reticular ground glass or honeycomb shadows in both lungs.

Diagnosis

Differential diagnosis

Clinical needs to be differentiated from emphysema and heart failure.
