Purpose Of ReviewThe purpose of this review is to provide a summary of the perioperative studies that have examined transdermal lidocaine (lidocaine patch) as an analgesic and put the evidence in context of the likely overall benefit of transdermal lidocaine in the perioperative period.Recent FindingsSeveral randomized controlled trials have been published in the past 4 years that concluded transdermal lidocaine can reduce acute pain associated with laparoscopic trocar or cannula insertion. Transdermal lidocaine may reduce short-term pain after surgery in selected surgery types and has a low risk of toxicity but its overall clinical utility in the perioperative setting is questionable. Transdermal lidocaine does not consistently reduce opioid consumption after surgery and has not been shown to improve patient function.
