  • Comparing Through-the-Needle With Suture-Method Catheter Designs for Popliteal Nerve Blocks

    Sorry, accepting new patients by invitation only

    Following painful surgical procedures, postoperative analgesia is often provided with a single-injection peripheral nerve block. Hothe investigatorsver, even with the longest-acting FDA-approved local anesthetic currently available-bupivacaine-the block duration is measured in hours, while the surgical pain may persist for days. A continuous peripheral nerve block allows a prolonged block, consisting of a percutaneously-inserted catheter with its orifice adjacent to a target nerve/plexus through which local anesthetic may be administered. Two basic perineural catheter designs currently exist: (1) catheters that are inserted either through or over a straight hollow-bore needle; and, (2) catheters that are attached to the back of a hollow suture-shaped needle that pulls the catheter adjacent to the target nerve ("suture-method" design). To date, a comparison of the relative risks and benefits of these two designs have not been investigated. The investigators therefore propose a randomized, observer-masked, controlled, parallel-arm, clinical trial to compare these two catheter designs when used to provide post-surgical analgesia following foot and ankle surgery.
