Ambulatory use of high-dose intravenous morphine for severe pain

A case is presented that describes the use of an intravenous morphine infusion to treat severe pain in an outpatient setting. The patient had severe pain secondary to tumor involvement of the brachial plexus. Morphine was administered as a concentrated solution (50 mg/ml), using an autosyringe (model AS-2F) via a Hickman catheter. The dose was titrated to pain relief. A dose of 200-250 mg/h was required.
