Summary: What is known and objective: The exponential increase in chronic opioid consumers resulted in more challenges regarding post‐operative pain management. Considering the usual hyperalgesic response to pain and the increased opioid‐tolerance, a multidrug approach should be desirable. Case description: We described the strategy in pain management of a patient receiving methadone maintenance treatment, who underwent surgery associated with moderate post‐operative pain. The combination of balanced general anaesthesia and intraoperative continuous low‐dose infusion of ketamine assured an appropriate control of post‐operative pain without increasing opioid consumption. Besides, it was not associated with psychomimetic effects. What is new and conclusion: Ketamine can effectively reduce opioid requirements in chronic opioid users on methadone maintenance therapy and should therefore be considered promptly as part of a multimodal perioperative analgesia management in this category of patients.
