血管活性药物（Vasoactive agents） Microinjection pump formula: Pump speed (ml/h) = standard rate (ug/kg/min) * 0.06 * * body weight (kg) / ml syringe dose (mg). With the 50ml injector as an example, the pump speed (ml/h) = standard rate (ug/kg/min) * body weight (kg) * 3 / dose (mg). When the weight (kg) * 3 value is used as the drug dose, the pump speed (ml/h) and the standard rate (ug/kg/min) are corresponding, at which time the pump speed 1ml/h corresponds to the standard rate 1ug/kg/min. When the weight (kg) x 0.3 is used as a drug dose, the ratio of the pump speed (ml/h) to the standard rate (ug/kg/min) is 10:1, or 10ml/h, equivalent to 1ug/kg/min. The 1.: the weight of dopamine (kg) * 3mg diluted to 50ml. as the pump speed is 1ml/h, the amount of pump is 1 g/kg.min, 1~20 dose of g/kg.min; the initial dose of 5 g/kg.min. * 2.: distribution method with dopamine, dobutamine dose 1~20 g/kg.min, initial dose of 1 g/kg.min. 3. / 1 50mg specifications: sodium nitroprusside. 5%GS 50ml + sodium nitroprusside 50mg, that is, 1mg/ml (1000 g/ml), the starting dose 5~10 g/min g/kg.min (0.3~0.6ml/h), commonly used doses of 10~200 mu g/min (0.6~12ml) or 0.1~2 mu. - 4.: Nitroglycerin specifications 1ml:5mg. (kg weight x 0.3) mg dilution to 50ml, such as pump speed is 1ml/h, pump volume is 0.1 g/kg.min. Or: NS 44ML + nitroglycerin 30mg, that is 0.6mg/ml (600 g/ml), the common dose is 10~20 g/min or 0.1~2 mu g/kg.min, the starting dose is 5~10 g/min (0.5~1ml/h). (Note: in addition, we can use nitroglycerin 10mg with physiological saline to 50ml, pump speed kg * 0.3ml/h corresponding to 1 g/kg.min, such as nitroglycerin 30mg, then pump speed kg * 0.1ml/h corresponds to 1 g/kg.min) 5. - norepinephrine: specification: 2mg 2ml. (kg weight x 0.3) mg diluted to 50ml, such as pump speed is 1ml/h, the pump intake is 0.1 g/kg.min, the common dose is 0.1~2 g/kg.min, the starting dose is 0.1 g/kg.min (should use norepinephrine through central vein). The 6. specifications: 1mg 1ml: epinephrine. The
