一、概念:血浆渗透压低于正常为低渗血症,低渗血症严重者可伴发脑症状,伴有脑症状的重症低渗血症称为低渗性脑病。二、病因及发病机理:肺心病、肺性脑病患者为什么会发生低渗性脑病,概括地讲,大致有如下几种原因:1.患者可因原发病反复发作,病期延长、长期进食量过少而发生营养不良,致使血浆渗透压下降。2.患者唯恐发生浮肿或加重咳喘而自动长期限制进盐。血浆渗透压的高低主要取决于体液的晶体渗透压,而晶体渗透压的高低取决于无机盐的含量。血浆渗透压1/2是由 Nacl 组成的。由于长期限制进盐,致使血浆渗透压降低。3.由于接受不正确的治疗,例如持续大剂量的
First, the concept: Plasma osmolality is lower than normal for hyponatremia, hyponatremia may be associated with severe brain symptoms, severe hyponatremia associated with brain symptoms known as hypotonic encephalopathy. Second, the etiology and pathogenesis: pulmonary heart disease, pulmonary encephalopathy occurs in patients with hypotonic encephalopathy, generally speaking, there are roughly the following reasons: 1. Patients may be due to recurrent episodes of primary disease, prolonged illness, long-term consumption of food over Less occurrence of malnutrition, resulting in decreased plasma osmolality. 2 fear of patients with edema or aggravate cough and long-term limit to automatically enter the salt. The level of plasma osmotic pressure depends mainly on the body fluid osmotic pressure, and the level of crystalline osmotic pressure depends on the content of inorganic salts. Plasma osmotic pressure 1/2 consists of Nacl. Due to long-term restrictions into the salt, resulting in decreased plasma osmolality. 3. Due to incorrect treatment, such as sustained high-dose
