The use of continuous femoral nerve blocks versus extended release epidural morphine: a study comparing outcomes in total knee arthroplasty procedures

Abstract

The purpose of this study was to compare the effectiveness of continuous femoral nerve block (CFNB) protocol, to extended release epidural morphine DepoDur protocol, in patients having a total knee arthroplasty (TKA) enrolled in a structured joint replacement educational program. Overall, the results of this randomized controlled study demonstrate that CFNB and DepoDur protocol pain strategies were well tolerated in TKA patients during this study with expected side effects and appropriate side effect management. Moreover, the DepoDur protocol enhanced pain management experience and satisfaction and provided superior prolonged analgesia compared with CFNB protocol. The occurrence of adverse events, cost, length of stay, and functional outcomes was comparable between groups.
