Local infiltration analgesia uses a combination of local anesthetics, nonsteroidal anti-inflammatory drugs and epinephrine and is typically injected during surgery. The researchers compared this method with intrathecal morphine after total knee arthroplasty.
In the double-blind study, 50 patients were scheduled to undergo TKA under spinal anesthesia. The patients were divided into two groups; one group received intrathecal morphine and the other received LIA.
