For manually-controlled infusion Remifentanil can be diluted to concentrations of 20 to 250 micrograms/ml (50 micrograms/ml is the recommended dilution for adults and 20 to 25 micrograms/ml for paediatric patients aged 1 year and over). For TCI the recommended dilution of Remifentanil is 20 to 50 micrograms /ml.

How do you calculate remifentanil?

We suggest a simple formula to quickly calculate the rate in ml/h:For adults, the recommended dilution is 50 μg/ml. Multiply the weight (in kg) by 0.12 to give the rate in ml/h that equates to 0.1 μg/kg/min. From this, the rates for 0.2 – 1 μg/kg/min can be rapidly calculated.
