I do not have experience with regional blocks on the lower extremity.
For lacs involving the toes, I use digital block. For lacs on the dorsal
aspect of the foot local anesthesia works as well as anywhere else. I use
buffered 1% Lydo (with Bicarb 10:1) and a 25 0r 27 needle.
Lacs involving the sole are a little more difficult, however thorough
infiltration of the wound edges from inside the lac area provides good
anesthesia for a simple skin closure.
For large, extensive lacerations or foreign bodies deep in the sole I
usually send them to the OR.
