Reduction of Leakage from Insertion Site During Continuous Femoral Nerve Block with Catheter-Through-Needle Versus Catheter-Over-Needle Technique for Postoperative Analgesia After Total Knee Arthroplasty: A Randomized Controlled Trial
Abstract:Background: Continuous femoral nerve block (CFNB) is a common procedure used for postoperative analgesia in total knee arthroplasty. Continuous nerve block using a conventional needle (catheter-through-needle/CTN) is complicated by leakage of the anesthetic from the catheter insertion site. A new type of needle (catheter-over-needle/ CON) is now available, which is believed to reduce leakage as the diameter of the catheter is larger than that of the needle. The purpose of this study was to compare leakage from… Show more
