[Emergency pain treatment--ambulatory intravenous morphine titration in a patient with cancer pain].

Even when the guidelines for cancer pain management are followed, acute severe pain requiring immediate treatment will occur in some patients. Titration with intravenous morphine may provide fast and efficient pain relief and give an indication of the amount of opioid necessary for continuous treatment. In cooperation with a general practitioner we performed an intravenous morphine titration in a patient with severe cancer pain at home. Adequate analgesia was reached with 20 mg intravenous morphine. Blood pressure, cardiac frequency and oxygen saturation did not change. No side effects were reported during the titration, and the previous regimen with tramadol 150 mg per day was switched to slow release morphine 300 mg per day. This medication was prescribed by the general practitioner and provided good pain relief until the patient died two weeks later. We conclude that intravenous morphine titration may be performed even in cancer patients at home, adequate monitoring, however, should be available.
