Mulitmodal Analgesia for Postoperative Total Knee Arthroplasty

Background: Postoperative pain after a total knee arthroplasty (TKA) is a major concern for the patient and nurse. Pain after a TKA can be severe and, when inadequately controlled, can impair or prevent functional rehabilitation with physiologic, psychologic, and economic consequences (Sawyer, 2004). With multiple pain management regimens, healthcare providers need data on approaches that provide optimal postoperative pain relief with minimal side effects. Purpose: This retrospective study examined whether there were differences between regional anesthetics used for TKAs in their ability to control postoperative pain with fewer side effects. Methods: Retrospective chart review of two hundred fifty seven charts. Results: Patients who received all 3 anesthetic modalities (intrathecal morphine sulfate, single-shot femoral nerve block, and wound catheter) had better pain control postoperative TKA and requested less opioids.
