Pain management associated with surgery is a constant concern of the health team as well as the patient. Multiple proposals for analgesia have been made in the perioperative context. The use of opioids with rapid effect and easy titration in the intraoperative period are currently frequent; to then perform a postoperative analgesic control with drugs with a longer half-life, usually achieving adequate pain management. However, sometimes the standard analgesic scheme is not enough. The problems associated with this situation have led to the need for high doses of opioids in the postoperative period, with the requirement for monitoring, health personnel, and the adverse effects that these involve. Methadone is a long-acting, rapid-onset opioid, the latter secondary to its long elimination half-life. It is presumed that these characteristics have led patients to report adequate pain management, which has been related to a decrease in the need and dose of rescue opioids, in addition to delaying the requirement of these if necessary during the postoperative. These properties allow methadone to be a potential solution to perioperative pain management.
