Prescribed: Begin propofol IV infusion at 9 mL/hr Available: propofol 1000 mg/100 mL Patient's weight: 75 kg Calculate how many mcg/kg/min the patient is receiving? Record your answer to whole number.

Identify the ordered infusion rate and available concentration Infusion Rate: 9 mL/hr Available Concentration: 1000 mg/100 mL = 10 mg/mL Calculate the total mg/hr being infused Total mg/hr = 9 × 10 = 90 mg/hr Convert mg/hr to mcg/min 90 mg/hr × 1000 mcg/mg = 90,000 mcg/hr 90,000 ÷ 60 min = 1,500 mcg/min Calculate mcg/kg/min Patient weight: 75 kg Rate = 1,500 ÷ 75 = 20 mcg/kg/min
