Catheter-based Peripheral Regional Anesthesia After Total Knee Arthroplasty

• Status: Completed
• Trial end date: 2019-04-01
• Target enrollment: 0
• Participant gender: All

Summary

BACKGROUND

Total knee arthroplasty can be severely painful, and peripheral regional anesthesia is highly recommended as part of the perioperative pain treatment. Whether catheter-based techniques are better than single injection techniques are debatable. Furthermore, in catheter-based techniques, whether a low-dose automated, periodic infusion can produce similar analgesic effectiveness compared to a conventional, high dose, continuous infusion has never been explored.

AIM Comparison of the analgesic effectiveness of a low-dose automated, periodic infusion, a conventional continuous infusion and patient-controlled boluses only in catheter-based adductor canal blocks for patients undergoing total knee arthrplasty.
