The Pharmacokinetics and Effectiveness of Local LevoBupivacaine Injection on Primary Total Joint Replacement Model.

Summary

Total joint replacement is an ideal procedure to treat end stage joint disease. Good post-op pain relief could accelerate patient recovery and rehabilitation, and decrease admission days and medical cost. Local injection of LevoBupivacaine is an effective method in post-operative pain control. The effectiveness of local analgesia was noticed clinically. However, thorough studies about the pharmacokinetics of LevoBupivacaine, maintenance of effect, influence of post-operative rehabilitation are not well studied in different way of injection. The purpose of this study is to evaluate and analyze the pharmacokinetics and effect of local Levobupivacaine injection in different ways, the amount of post-operative fentanyl requirement after local injection, time to first fentanyl request, pain score, immediate post-operative function, side effect of analgesic agents, and medical cost, and to improve the quality of total joint replacement post-operative care.
