Effects of Catheter Location on Postoperative Analgesia for Continuous Adductor Canal and Popliteal-Sciatic Nerve Blocks

Summary

Currently, continuous adductor canal and popliteal-sciatic nerve blocks are used commonly for lower extremity post-operative pain control, specifically for total knee arthroplasty and foot/ankle surgery, respectively. A perineural catheter used to infuse local anesthetic for postoperative analgesia may be placed at various locations along the target nerves. Investigations of single-injection peripheral nerve blocks suggest that the onset of the block might be faster with one location over the other; but, the success rates are equivalent. However, remaining unknown is whether there is an optimal location to place a perineural catheter as part of a continuous peripheral nerve block.
