HealthDay News — For patients undergoing robotic cardiac valve surgery, lidocaine 5% patches do not reduce acute or persistent pain.
Bruce Vrooman, MD, from the Cleveland Clinic, and colleagues conducted a randomized, placebo-controlled trial among patients having robotic cardiac valve surgery. Patients were randomized to 5% lidocaine patches or identically appearing placebo patches. Patches were applied around each incision until pain resolved or for six months, for 12 hours per day.
Published in Pain Medicine, the report revealed that acute pain scores, opioid use, and incidence of persistent pain were low. Lidocaine patches had no impact on measures of acute or persistent incisional pain. For lidocaine patch minus placebo, the estimated difference in mean Pain Disability Index was −2.5 (P = 0.28).
“In summary, lidocaine 5% patches did not reduce acute or persistent pain in patients having robotic cardiac valve surgery, though pain scores were low in both treatment groups,” the authors write. “Clinicians should choose alternative analgesic approaches for these patients.”
The study was funded by Endo Pharmaceuticals.
