Effects of postoperative administration of celecoxib on pain management in patients after total knee arthroplasty: study protocol for an open-label randomized controlled trial
Abstract
BackgroundMultimodal analgesia is achieved by combining different analgesics and different methods of analgesic administration, synergistically providing superior pain relief when compared with conventional analgesia. Multimodal analgesia can also result in reductions in the side effects and complications of analgesia, thereby improving patient safety. Preventive analgesia, treatment before initiation of the surgical procedure, has a potential to be more effective in reducing pain sensitization than treatment initiated after surgery. Multimodal analgesia that includes prophylactic administration of selective cyclooxygenase-2 (COX-2) inhibitors can improve postoperative pain and reduce opioid analgesic consumption after total knee arthroplasty (TKA). However COX-2 inhibitors are not approved for use as preventive analgesia in Japan. Thus, assessing the effectiveness of COX-2 inhibitors during the early postoperative period is important to establish clinical practice guidelines in Japan. This study was designed to examine the effects of celecoxib administration immediately after surgery, in addition to multimodal analgesia, on postoperative pain management after TKA.Methods/DesignThis randomized, prospective, open-label controlled study will include 120 patients undergoing unilateral TKA. All patients will routinely receive single injections of femoral and sciatic nerve blocks, along with postoperative patient-controlled analgesia (PCA) with fentanyl. Patients will be randomly…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 120 participants or records.
