三、累积损失及其补充脱水一般指细胞外液水与电解质的减少。由于水与电解质减少的比例不同,又把脱水分为等张、低张和高张三种性质。等张脱水是水与电解质成比例地减少;低张脱水是电解质的减少多于水的减少,因此所 Third, the cumulative loss and its supplementary dehydration generally refers to the extracellular fluid and electrolyte reduction. Due to the different proportions of water and electrolyte reduction, the dehydration is divided into three kinds of properties: isotonic, low-tension and high-tension. Isotactic dehydration is a reduction of water in proportion to the electrolyte; low dehydration is the reduction of electrolytes more than that of water, so
