Neuraxial infusion for pain control: when, why, and what to do after the implant.

Neuraxial infusion therapy is an excellent option for selected patients with severe pain. Both epidural and intrathecal systems can be effective for multiple pains and are titratable, nondestructive, and very safe. Intraspinal therapy requires low opioid doses, has no motor, sensory, or sympathetic effects, and may have a lower side-effect liability than systemic therapy. Although most oncologists do not refer patients for intrathecal therapy, a recent study indicated that more oncologists would if they knew more about the therapy and if patients requested it. When permanent systems are used, close follow-up is essential. To obtain the maximum benefit from intraspinal therapy, pain management physicians and oncologists must communicate with each other and work together as partners.
