Abstract:
Objective To evaluate the efficacy and safety of local infiltration analgesia in the multimodal analgesia protocol.Methods Sixty patients who were scheduled to undergo TKA were randomly divided two groups:local infiltration analgesia (LIA) group (n=30) or the non-local infiltration analgesia (N-LIA) group (n=30).All patients were given Celecoxib 200 mg bid,3 days preoperative,and a single-injection femoral nerve block (SFNB) half an hour before the surgery (ropivacaine 3.3 g/L,30 ml).The LIA group was given local infiltration analgesia with ropivacaine (2.5 g/L,60 ml) and 0.1 mg epinephrine before suture the operative incision.The N-LIA group didn't do the LIA.Both of the two groups didn't use the patient controlled analgesia.The VAS scores,the knee joint range of motion,the muscle strength of quadriceps femoris and the side effects and complications were recorded.Results The VAS scores were lower in LIA group than in the N-LIA group,these scores at 2 h to 48 h after surgery at rest and after 24 h at motion had statistical significance.The range of motion and the muscular strength of quadriceps femoris in the LIA group were better than in the N-LIA group.In the LIA group the use of opioids was less and the side effects were lower.The average length of hospital stay after the operation was shorter in the LIA group than the N-LIA group.Conclusion This multimodal perioperative analgesia protocol that include SFNB and LIA offered improved pain control and minimal side effects to patients undergoing TKA.
