所有要求精确用量的强效药物都需要使用自动注射器。有许多药常需借助于计算工具计算患者的体重、剂量(μg/Kg)和药物稀释的方法。作者报道一种用于所有药物的简便稀释方法:用于1ml/h 或μg/Kg/min 的剂量。用蒸馏水将相当于3倍体重(Kg)的药量稀释至50ml:3×体重(Kg)=50ml 内的药量(mg),即1ml/h,或1μg/Kg/min。例1:重50Kg 患者的多巴丁胺——50×3=50ml 内的150mg,即1ml/h 或1μg/Kg/min。遇更强效的药物需要0.1μg/Kg/min 的剂量时有必要将该药物再稀释10倍:0.3×体重(Kg)
All of the potent drugs that require precise dosage require the use of auto-injectors. There are many drugs often need to calculate the patient’s weight, dose (μg / Kg) and drug dilution methods. The authors report a simple dilution method for all drugs: for doses of 1 ml / h or μg / Kg / min. The dose equivalent to 3 times body weight (Kg) is diluted with distilled water to a dose of 50 ml: 3 x body weight (Kg) = 50 ml, ie 1 ml / h, or 1 μg / Kg / min. Example 1: Dopamicin in 50 Kg Patient - 50 × 3 = 150 mg in 50 ml, ie 1 ml / h or 1 μg / Kg / min. In the event of a more potent drug requiring a dose of 0.1 μg / Kg / min it is necessary to re-dilute the drug 10-fold: 0.3 × body weight (Kg)
