Low-dose ketamine (LDK) may be useful for treatment for opioid-tolerant patients. We conducted a survey of patients and their treating clinicians regarding LDK for analgesia. ⋯ Low-dose ketamine may decrease patients' perception of pain. Most were satisfied with LDK for this purpose and would use it again. Whites were least satisfied with the use of LDK for analgesia. Physicians believed that ketamine is underused.
