Randomized Controlled Trial Clinical TrialPreemptive analgesia in children. Does it exist?
Preemptive analgesia has been evident in animals, but few adult human studies exist demonstrating this concept exist, and there are fewer still in children. Caudal epidural blocks with local anesthetics are often placed for postoperative analgesia in children. This study evaluated whether these blocks are more effective when placed prior to surgical incision. ⋯ Although preemptive analgesia has been successfully demonstrated in some earlier clinical studies, our results indicate that pre- and postincisional caudal epidural blocks with 0.25% bupivacaine were equally effective in children.

Comparative StudyLong-tapered double needle used to reduce needle stick nerve injury.
Needle trauma may cause peripheral nerve injuries during performance of peripheral nerve block. ⋯ The long-tapered needles produced the least number of transected nerve fibers after sciatic nerve puncture.
