Abstract:

BACKGROUND: Perioperative pain management is the focus in total knee arthroplasty. Looking for a safe and effective analgesic way has become one of the important tasks of the surgeons.
OBJECTIVE: To compare the analgesia and rehabilitation effect of the epidural analgesia and the femoral nerve analgesia after total knee arthroplasty, and to explore the relative multimodal analgesia proposal.
METHODS: Forty patients undergoing unilateral total knee arthroplasty were randomly selected, and the patients were divided into two groups according to different analgesia proposals: epidural analgesia group and femoral nerve analgesia group, 20 patients in each group. All patients received unilateral total knee arthroplasty and preoperative missionary and celecoxib administration under epidural analgesia. Patients in the epidural analgesia group were given analgesia with 0.2% ropivacaine and 2 ug/mL fentanyl after the replacement. The patients in the femoral nerve analgesia group were given analgesia with 0.2% popivacaine from the femoral nerve block vessel. The visual analog scores of the patients were observed at 6, 12 and 24 hours and 2-7 days after total knee arthroplasty, and the range of motion was recorded at 2-7 days after total knee arthroplasty.
RESULTS AND CONCLUSION: At 2-7 days after total knee arthroplasty, the visual analog scores of rest/movement pain were decreased in two groups, and the pain degree in the femoral nerve analgesia group was smaller than that in the epidural analgesia group. At 2-7 days after total knee arthroplasty, the range of motion of the patients in two groups was increased gradually, and the range of motion in the femoral nerve analgesia group was larger than in the epidural analgesia group. The results showed that both the epidural analgesia and the femoral nerve analgesia can relieve pain after total knee arthroplasty, but the femoral nerve analgesia can provide better pain relief than epidural analgesia, and it can lead to a quick functional recovery. Multimodal analgesia proposal can effectively control the pain.
