Efficacy of Pain Control in Different Bupivacaine Dose in Periarticular Injection in Bilateral Total Knee Arthroplasty

Overview

To study efficacy of postoperative pain control of different concentrations of bupivacaine for periarticular infiltration, part of multimodal analgesia, in bilateral total knee arthroplasty. To study plasma concentration of bupivacaine in patient who received spinal anesthesia and single shot bilateral adductor canal block and periarticular infiltration with bupivacaine for safety level.

Adequate postoperative pain control reduce postoperative morbidity, multimodal analgesia techniques is used for achieve this goal. multimodal analgesia for bilateral total knee arthroplasty are peripheral nerve block, periarticular infiltration, NSAIDs, gabapentins and others. patients undergoing bilateral total knee arthroplasty in siriraj hospital receive spinal anesthesia, single shot bilateral adductor canal block and bilateral periarticular infiltration with bupivacaine so patient receive a large dose of bupivacaine. the investigators study the efficacy of postoperative pain of reduced dose of bupivacaine for periarticular infiltration. and study plasma level of bupivacaine.
