A 10-kg patient with hypotension and sepsis requires a norepinephrine CRI, which will be administered using a programmable syringe pump. The norepinephrine must be diluted prior to administration using a solution such as D5W or 0.9% sodium chloride. The veterinary nurse receives the following orders:

Norepinephrine 
Dose Range0.1-0.5 µg/kg/min
Initial Concentration4 mg/mL
Diluted Concentration1 mL norepinephrine added to 59 mL D5W in a 60-mL syringe

A recent FDA safety communication recommended that healthcare professionals use caution when delivering drugs at rates <5 mL/h using programmable syringe pumps because of the potential for inaccurate dosing (high, low, or delayed).2 Is the flow rate of norepinephrine at the low dose rate specified for this CRI acceptable based on the FDA recommendation?

The veterinary nurse determines that the flow rate for the following norepinephrine CRI is too low, according to the recent FDA recommendation to use caution when delivering drugs via syringe pump at rates <5 mL/h.2 

Norepinephrine 
Dose Range0.1-0.5 µg/kg/min
Initial Concentration4 mg/mL
Diluted Concentration1 mL norepinephrine added to 59 mL D5W in a 60-mL syringe

In conjunction with this recommendation, the FDA also advised that healthcare providers use the smallest compatible syringe size to deliver low-flow-rate CRIs.2 What change can the veterinary nurse make to ensure this norepinephrine CRI is safely administered?
