title: Low-dose ketamine in the management of opioid nonresponsive terminal cancer pain.
abstract: Two patients with far-advanced cancer, near death, who were experiencing excruciating and intractable pain that was poorly responsive to rapidly escalating doses of morphine and hydromorphone were treated with low-dose intravenous ketamine (0.1-0.2 mg/kg). This intervention eliminated the need for any further opioid use, providing profound analgesia and a sense of calm during the last hours and days of these patients' lives. These case reports add to the small but growing body of clinical literature suggesting that ketamine may have a significant place in the care of patients with pain that is poorly responsive to opioids, or who experience dose-limiting adverse effects, near the end of life. This is an important matter to disseminate in order to reassure the public that we do have the tools necessary to keep the promise that no one need die with uncontrolled pain. This therapeutic approach may also serve to reassure concerned physicians that their efforts to assure pain relief may not be misconstrued as hastening death.
