Summary
BACKGROUND
Orthopedic surgery 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 nerve
blocks for patients undergoing orthopedic surgery to the foot or ankle.
