第一节纠正水和电解质紊乱的药物一、体液分布和体液中的电解质人体液分为细胞内液(占体重的40%)、组织间液(包括淋巴液、脑脊液,占体重的15%)和血浆(占体重的5%)。组织间液和血浆统称为细胞外液。细胞外液是浸浴细胞的内环境。内环境必须保证一定的容积、分布、渗透压、电解质种类和浓度以及酸碱度,即保证内环境的稳定。各种体液的比例,随着年龄不同而变化(表1)。总的说来,年龄越小,总体液越多。细胞外液也越多,加上调节机
The first section to correct the water and electrolyte disorders drugs First, the distribution of body fluids and electrolytes in body fluids Human fluid is divided into intracellular fluid (accounting for 40% of body weight), interstitial fluid (including lymph fluid, cerebrospinal fluid, accounting for 15% of body weight) And plasma (5% of body weight). Tissue fluid and plasma collectively referred to as extracellular fluid. Extracellular fluid is the internal environment of the bathing cells. The inner environment must ensure a certain volume, distribution, osmotic pressure, electrolyte type and concentration and pH, that is, to ensure the stability of the internal environment. The proportions of various body fluids vary with age (Table 1). In general, the younger, the more total fluid. Extracellular fluid is also more, with the regulator
