肺毛细血管压力增高和肺静脉高压是胸腔积液公认的原因,低蛋白血症是许多与胸膜渗出性疾病的特征,如肝硬化和肾病综合征。这些疾病形成的胸水常伴有许多其它的因素,如血浆容量增加或腹水。目前。有关单纯低蛋白血症导致胸腔积液的原因尚不明了,Eicl等对此进行了有益的探讨。 选择的标准为:住院24小时内行胸部X线、血清白蛋白和总蛋白水平检查的患者。但伴有充血性心力衰竭(CHF)、肺炎、未确诊的肺浸润、胸部恶性肿瘤、伴有胸腔积液的腹部疾病(如胰腺炎、卵巢癌、腹腔脓肿)、肾病综合征、肝衰者不属研究对象。4周内曾有胸部创伤、肺栓塞以及器官移植者
Pulmonary capillary pressure and pulmonary hypertension are pleural effusion recognized as the cause of hypoalbuminemia and many pleural exudative disease characteristics such as cirrhosis and nephrotic syndrome. Pleural effusion formed by these diseases is often accompanied by many other factors, such as increased plasma volume or ascites. Currently. The reason why simple hypoalbuminemia causes pleural effusion is unknown, and Eicl et al. The criteria chosen were: patients undergoing chest X-ray, serum albumin, and total protein levels within 24 hours of hospitalization. But associated with congestive heart failure (CHF), pneumonia, undiagnosed pulmonary infiltrates, chest malignancies, abdominal diseases with pleural effusions (eg, pancreatitis, ovarian cancer, abdominal abscess), nephrotic syndrome, Not a research object. There were chest trauma, pulmonary embolism, and organ transplants in 4 weeks
