Outpatient continuous interscalene brachial plexus block in cancer-related pain.

This case outlines the use of a continuous interscalene brachial plexus block to treat cancer-related pain. Using an elastomeric device, the patient's previously intractable pain was controlled and he was able to return home. Furthermore, the patient developed a pragmatic and effective method of balancing loss of power and sensation against pain control using the flow restrictor. This case illustrates the potential of an integrated approach to cancer pain management to obtain rapid pain relief in the acute hospital setting.
