Meta Analysis
The effect of lidocaine patch for postoperative pain: A meta-analysis of randomized controlled trials.
The role of lidocaine patch (LP) in reducing postoperative pain by local anesthetic absorption has been evaluated in several studies; however, these trials have shown inconsistent results. This meta-analysis aimed to identify the benefits of LP, focusing on its pain-reducing and morphine-sparing effect in patients after surgery. ⋯ LP can lower postoperative pain without side effects, compared to placebo or no patch. However, its morphine-sparing effect remains unclear.
