用于静脉治疗的药物一般制成易溶的盐类,钾、钙、镁盐是临床上最常用的静脉注射药物。由于K~+、Ca~(++)、Mg~(++)具有多种生理和药理学作用,在静脉注射时常发生某些意外,本文对其静脉给药应注意的一些问题,分别作一简要的介绍。一、钾盐钾离子是细胞内的主要阳离子,为正常 Drugs used for intravenous treatment are generally made of soluble salts, potassium, calcium, magnesium is the most commonly used clinical intravenous drugs. Because K ~ +, Ca ~ (++), Mg ~ (++) have a variety of physiological and pharmacological effects, some accidents often occur during intravenous injection. Some problems that should be noticed in this paper are A brief introduction. First, potassium Potassium is the intracellular cation, normal
