Because of the disorder of internal environment and the low immunity of CRF patients, the lung diseases are mainly affected by the internal and external pathogenic factors of the receptor, mainly including uremia, pulmonary edema, pleural effusion and so on.

What are the respiratory complications in chronic renal failure?

Uremic lung: also known as uremia, pulmonary edema, uremia pneumonia. Its symptoms are mild, early only uremia caused systemic symptoms, with the development of the disease gradually appear mild to moderate cough, cough a small amount of sticky sputum and breathing difficulties. For the development of interstitial fibrosis, dyspnea and cyanosis aggravated. Small and medium-sized hemoptysis is also an important symptom. With cardiogenic pulmonary edema, pulmonary infection and pulmonary hemorrhage and nephritis syndrome differentiation.

Uremic pleural disease: the incidence is 15% to 20%, with pleural friction, chest pain or chest discomfort, difficulty in breathing or fever. The pleural friction rub lasts 1~15 days and may be accompanied by exudation. There was no relation between blood urea nitrogen and exudation.

Pulmonary calcification: CRF often causes calcification of soft tissue, and the lung is the most common site. The clinical manifestations were chronic dyspnea or acute or subacute respiratory failure. The chest radiograph was completely normal. Calcium removal, removal of parathyroid glands, low phosphorus diet, oral administration of alumina, and the use of low calcium dialysate, increasing the number of dialysis sessions or durations, can reverse calcification.

Uremic pulmonary edema is one of the common emergencies in the Department of nephropathy. When the CRF patients, especially with oliguria, anuria, such as sudden severe dyspnea, orthopnea, with fear, a sense of suffocation, pallid, cyanosis, sweating, cough, expectoration, hemoptysis and may be accompanied by a large pink foam sputum, pulmonary rales with two symmetry and wheeze weak pulse, heart rate, acute pulmonary edema should be considered.
