RESUMEN
Background: Although opioids are used first line for cancer pain and commonly for complex noncancer pain, there are risks associated with their use and not effective for all types of pain. There's a need to identify and develop clinical practice guidelines for nonopioids for the treatment of refractory pain. Methods: Our study collected information from national clinical practice guidelines for ketamine, lidocaine, and dexmedetomidine with the aim to identify consensus among the different practices. Results: Fifteen institutions nationally participated in the study and only nine of those institutions had guidelines and were permitted by their health system to share them. Of the institutions that participated, 44% had guidelines for ketamine and lidocaine, and only two institutions (22%) had guidelines for ketamine, lidocaine, and dexmedetomidine for refractory pain. There were variations in restriction of the level of care and prescribers, dosing, and determination of efficacy. There were trends of consensus in monitoring for side effects. Conclusion: This study serves as a starting point for a snapshot of the use of ketamine, lidocaine, and dexmedetomidine for refractory pain, but further studies and increased participation of institutions are needed to develop consensus clinical practice guidelines.
