Randomized Controlled Trial Comparative Study
Comparison of bupivacaine and lidocaine with epinephrine for digital nerve blocks.
This study compared the efficacy in terms of pain of injection, time of onset and duration of action of digital blocks of bupivacaine 0.5% alone and lidocaine 1% with epinephrine (1:100,000). ⋯ Lidocaine (1%) with epinephrine (1:100 000) was significantly less painful and had a shorter duration of action than bupivacaine (0.5%), which had a similar onset of action for digital nerve block.
