How do you dilute remifentanil for infusion?

Is diamorphine better than pethidine?
Injections – diamorphine This is an opioid injection with similar actions and side effects to pethidine, taking 30 minutes to work. Diamorphine has been shown to be a little better for pain relief in labour than pethidine and many women are more satisfied with diamorphine.
How is the infusion rate of remifentanil calculated?
The dose of remifentanil when used as an infusion is calculated in µg.kg −1 .min −1. Certain infusion pumps can calculate the rate in ml.h −1 when the concentration of the drug and the dose required are entered. When you do not have one of these clever pumps, you need a calculator or one of the infusion rate tables supplied by Ultiva.
