Local Anesthetic Infiltration for Pain Control After Orthopedic Wide Excision

August 3, 2026 updated by: Chang-Hoon Koo, Seoul National University Hospital

Analgesic Effect of Subcutaneous Local Infiltration Anesthesia Before Skin Closure on Postoperative Pain in Patients Undergoing Orthopedic Wide Excision: A Prospective Double-Blind Randomized Controlled Trial

This study evaluates whether injecting a local anesthetic mixture (ropivacaine, morphine, ketorolac, and epinephrine) under the skin at the incision site before wound closure reduces pain after orthopedic wide excision surgery for bone or soft tissue tumors. Participants will be randomly assigned to receive either the local anesthetic mixture or a saline control injection. Neither participants nor the study team assessing outcomes will know which treatment was given. The main goal is to determine whether this injection reduces the amount of opioid pain medication needed during the first 24 hours after surgery. The study will also assess pain scores, nausea and vomiting, and quality of recovery.
