TL;DR: Cessation of the infusion or addition of clonidine to the IDDS admixture in conjunction with close clinical monitoring may be reasonable treatment options in patients with an asymptomatic or mildly symptomatic inflammatory mass.
Abstract: Intrathecal granuloma formation has commonly been described with morphine therapy. It has been suggested that a high concentration of intrathecal morphine may be responsible for this complication. Much less commonly, intrathecal hydromorphone has been associated with intrathecal granuloma formation. In the current case we report the evaluation and management of an intrathecal granuloma in a patient receiving a relatively high concentration of intrathecal hydromorphone. A nonsurgical, conservative approach to management involves stopping the infusion and observing the patient for improvement as the granuloma mass often slowly resolves once the infusion is stopped. Cessation of the infusion or addition of clonidine to the IDDS admixture in conjunction with close clinical monitoring may be reasonable treatment options in patients with an asymptomatic or mildly symptomatic inflammatory mass. In the current study, rapidly declining neurologic function with a confirmed inflammatory mass adherent to the spinal canal necessitated urgent surgical intervention. Though use of intrathecal hydromorphone still represents an off label application, this opiate is commonly employed as an alternative first line analgesic agent. This case report highlights the potential of high-dose and high infusate concentration intrathecal hydromorphone to form an inflammatory granuloma.

TL;DR: In this case series, anesthetic management and postoperative analgesic issues in three patients with indwelling intrathecal drug delivery systems placed for treatment of chronic pain are discussed.
Abstract: The use of intrathecal medications in the treatment of chronic pain is becoming more commonplace. As such, the incidence of encountering patients receiving therapy via an intrathecal drug delivery system in the perioperative period will also increase. In this case series, we discuss anesthetic management and postoperative analgesic issues in three patients with indwelling intrathecal drug delivery systems placed for treatment of chronic pain.

TL;DR: Current evidence suggests that opioid-induced pain sensitivity could be prevented by interrupting the cellular and molecular changes associated with the development of opioid tolerance, and may lead the way to a new period in which patients prone to opioid- induced pain could be identified, allowing one to tailor pharmacologic pain therapy to each patient.
Abstract: Opioid-induced pain or opioid tolerance should be considered when opioid therapy fails to provide expected analgesic effects or when there is unexplainable pain exacerbation following opioid treatment. As a result, an increase in the opioid dosage may not be the solution to ineffective opioid therapy for chronic pain management. A decrease in the opioid mass may actually provide pain relief in many instances. At one time, it was anticipated that opioid-induced pain was related to upregulation of NMDA receptors with a downregulation of mu receptors. However, there is growing evidence to suggest the opioid receptor-based hyperalgesic mechanism may be directly modulated by the NMDA receptor. Furthermore, the mechanism that causes opioid tolerance may be the same mechanism that causes opioid-induced pain. Current evidence suggests that opioid-induced pain sensitivity could be prevented by interrupting the cellular and molecular changes associated with the development of opioid tolerance.
