REBEL EMWhen selecting a local anesthetic agent for skin wounds I have historically been taught to use lidocaine to provide a faster onset, and to use bupivacaine for a longer duration of action. It can be time consuming to find 0.5% Bupivacaine with epinephrine and 2% Lidocaine with Epinephrine to produce a final mixture of 1% Lidocaine and 0.25% Bupivacaine with Epinephrine.
- If there is no difference in effect between these agents time could be saved when drawing up local anesthetics.
