三、血清钾含量比浊过筛法: 钾主要分布于细胞内,对维持细胞内液的渗透压有重要作用。体内K~+的动向与水分、Na~+和H~+的转移有密切联系。钾代谢失常往往导致水及酸硷平衡紊乱。 1.临床常见血钾变化:临床常见缺钾、血钾过低者,即指体内钾总量减少而言。血钾浓度低于3.5毫当量/升,为血钾过低,它比高钾更为有意义,常见于以下几种情况: (1)摄入不足:见于长期禁食,而静脉补液内又
Third, the serum potassium turbid sieve method: potassium is mainly distributed in the cells, to maintain the osmotic pressure of intracellular fluid has an important role. In vivo K ~ + movement and water, Na ~ + and H ~ + transfer are closely linked. Potassium metabolic disorders often lead to water and acid-base balance disorders. 1. Common clinical changes in serum potassium: common clinical potassium deficiency, hypokalemia who refer to the reduction of total potassium in terms of body. Blood potassium concentration of less than 3.5 meq / L, hypokalemia, it is more meaningful than potassium, common in the following situations: (1) Inadequate intake: seen in long-term fasting, and intravenous rehydration
