正常成人机体总钾量为140g～150g。其中2%在细胞外,98%在细胞内。正常血清钾3.5～4.5mmol/L,低于此数值时称为低血钾。现将补钾法介绍如下。1 静脉补钾法一般用0.3%氯化钾溶液进行静脉点滴。由于肌力的恢复与细胞内外钾的平衡有关,生理学试验表明,静脉补钾后约需15小时内外钾才能达到平稳。因为细 Normal adult body total potassium is 140g ~ 150g. Of these, 2% are extracellular and 98% are intracellular. Normal serum potassium 3.5 ~ 4.5mmol / L, below this value is called hypokalemia. Potassium method now introduced below. 1 intravenous potassium method generally 0.3% potassium chloride solution for intravenous drip. Due to the recovery of muscle strength and intracellular potassium balance, physiological tests show that within about 15 hours after intravenous potassium, potassium can be achieved within the smooth. Because of fine
