体钾特别是血钾的过大变动,可危及生命。临床上出现血钾过低时,则及时补充适量的钾是唯一有效的抢救措施。静脉滴注氯化钾溶液如速度过快,又易致血钾突然升高而引起心跳骤停、死亡。血钾浓度主要反映细胞外钾离子水平,血钾过高或接近正常而细胞内严重缺钾的情况,并不少见。天冬钾镁注射液是 Body potassium, especially excessive changes in serum potassium, can be life threatening. Clinic appears hypokalemia is too low, then the timely replenishment of potassium is the only effective rescue measures. Intravenous infusion of potassium chloride solution, such as too fast, but also prone to sudden increase in serum potassium caused by sudden cardiac arrest, death. It is not uncommon for serum potassium concentrations to primarily reflect extracellular potassium levels, hyperkalemia levels that are either too high or nearly normal and intracellularly severe potassium deficiency. Aspartate potassium magnesium injection is
