Answer:
The first step is to calculate the total dose of noradrenaline that the patient needs per minute:
10 mcg/kg/min x 60 kg = 600 mcg/min
The next step is to convert the dose from micrograms to milligrams, since the strength of the noradrenaline solution is given in milligrams:
600 mcg/min ÷ 1000 = 0.6 mg/min
Since the strength of the noradrenaline solution is 160 mg in 50 ml, we can use the following formula to calculate the infusion rate in ml/hr:
Infusion rate (ml/hr) = Dose rate (mg/min) x 60 ÷ Concentration (mg/ml)
Infusion rate (ml/hr) = 0.6 x 60 ÷ 160
Infusion rate (ml/hr) = 0.225
Therefore, the syringe should be run at a rate of 0.225 ml/hr.
