What are Peripheral Nerve Blocks?
“Peripheral nerve blocks” are specialized regional blocks that can be performed as a single injection of numbing medications, or as a continuous infusion through a soft, thin tube. Your anesthesiologist will discuss with you which type of block is best for you. For single injection nerve blocks in general, the numbness may last 6-12 hours. Much longer numbness, up to 24-36 hours is not uncommon for certain lower leg blocks. As the nerve block “wears off,” a feeling of “pins and needles” may be experienced. The hospital staff will instruct you on what type of peripheral nerve block you have had and how to take your pain medications before the block wears off.
