Efficacy of Continuous Brachial Plexus Block for Intractable Cancer Pain in a Terminal Patient

We report a case of terminal cancer in which continuous peripheral nerve block provided effective relief for cancer-related pain that was difficult to control with pharmacotherapy. A 70-year-old woman with thyroid cancer, paraplegia due to multiple bone metastases, and cauliflower-like proliferation of skin metastasis on the left upper arm was receiving inpatient palliative care. Intractable pain during treatment of the tumor and when changing body position due to metastatic tumor and pathological fracture of the left humerus was difficult to control with pharmacotherapy. Continuous interscalene brachial plexus block was therefore performed, resulting in effective pain relief over the subsequent 38 days before death. Ultrasound-guided continuous peripheral nerve block can be performed at the bedside in patients in poor general condition who cannot tolerate neuraxial block, and should be considered in cases of terminal cancer patient suffering from intractable pain despite pharmacotherapy.
