Effects of Catheter Location on Postoperative Analgesia for Continuous Adductor Canal and Popliteal-Sciatic Nerve Blocks
In Brief
A Phase 4 clinical trial evaluating ropivacaine 0.2% for Post-surgical Pain and 3 related conditions. Completed, enrolled 117 participants across 1 site.
Detailed 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.
