Catheter Orifice Configuration (Six-hole Versus End-hole) on Post-operative Analgesia After Total Knee Arthroplasty.

Summary

Multiorifice catheters have been shown to provide superior analgesia and significantly reduce local anesthetic consumption compared with end-hole catheters in epidural studies. This prospective, blinded, randomized study tested the hypothesis that, in continuous femoral nerve block (CFNB) under ultrasound guidance, multiorifice catheter would reduce local anesthetic consumption at 24h compared with end-hole catheter.
