プレガバリン内服困難となった後にリドカイン塩酸塩静注が奏功した 転移性癌浸潤による神経障害性疼痛の一例

The concomitant administration of adjuvant analgesics is recommended for neuropathic pain due to metastatic invasive cancer, because such pain may respond poorly to analgesic agents such as non-opioid analgesics and opioids. We report the case of a 44-year-old female patient with severe pain caused by a lumbosacral plexus injury associated with a failure of oral pregabalin（ 200 mg daily for 2 weeks）. We administered lidocaine hydrochloride（ drip infusion 960 mg/day）, which successfully relieved the pain.
