Pain Management Considerations in Patients With Opioid Use Disorder Requiring Critical Care.

The opioid epidemic has resulted in increased opioid-related critical care admissions, presenting challenges in acute pain management. Limited guidance exists in the management of critically ill patients with opioid use disorder (OUD). This narrative review provides the intensive care unit clinician with guidance and treatment options, including nonopioid analgesia, for patients receiving medications for OUD and for patients actively misusing opioids. Verification and continuation of the patient's outpatient medications for OUD regimen, specifically buprenorphine and methadone formulations; assessment of pain and opioid withdrawal; and treatment of acute pain with nonopioid analgesia, nonpharmacologic strategies, and short-acting opioids as needed, are all essential to adequate management of acute pain in patients with OUD. A multidisciplinary approach to treatment and discharge planning in patients with OUD may be beneficial to engage patients with OUD early in their hospital stay to prevent withdrawal, stabilize their OUD, and reduce the risk of unplanned discharge and other associated morbidity.

Shot in the dark: three patients successfully treated with onabotulinumtoxin A injections for relief of post-traumatic chronic headaches and dystonia induced by gunshot wounds.

Three patients ranging from 49 to 61 years-old presented to our pain clinic after failing multiple treatment attempts for debilitating, chronic post-traumatic headaches, neck pain and involuntary muscle spasm following gunshot wounds to the head, neck and face. Concurrent cervical dystonia was noted in each patient on presentation. All patients were treated with onabotulinumtoxin A (ONA) injections in the head and neck. Each patient reported between 70% and 100% improvement of their headache pain, neck pain and spasm with a significant reduction in the frequency, duration and intensity of their headaches. This level of improvement has been successfully maintained in all three patients with regular ONA injections at 90-day intervals. Two patients experienced a single relapse in symptoms when scheduling conflicts caused them to miss their regularly scheduled ONA injections by several weeks. These symptoms resolved when their ONA injections resumed, suggesting that ONA is the causative agent alleviating their symptoms.
