Epidural Conversions

Desired fentanyl concentration:
Desired bupivacaine concentration (0.5% vials):

Final volume:

Common agents: bupivacaine, fentanyl, ropivacaine

Volumes listed below assume a final volume of 250 ml. If a volume other than 250ml is requested and any of the following additives are required (bupivacaine, fentanyl - alone or in combination), use our calculator above. Using this chart: Example order: Epidural: 0.125% bupivacaine with fentanyl concentration of 2 mcg/ml. ---------------------------------------------- Using the table below, this would require 62.5 ml of bupivacaine and 10 ml of fentanyl for a total volume of 62.5 + 10 = 72.5ml. Remove 72.5 ml from a 250 ml bag and then add the additives listed above for a total volume of 250 ml.
