    AbstractCritical limb ischemia (CLI) is limb pain occurring at rest or impending limb loss as a result of lack of blood flow to the affected extremity. CLI pain is challenging to control despite multimodal pharmacologic analgesia and surgical intervention. We describe the successful use of a continuous local anesthetic infusion via an infraclavicular nerve catheter to control severe refractory ischemic upper limb pain in a patient with metastatic lung cancer for whom surgical and pharmacological intervention was unsuccessful. As her opioid requirements increased due to worsening ischemic pain, she subsequently developed opioid toxicity, hence prompting the palliative use of a tunneled infraclavicular nerve catheter under ultrasound guidance to minimize opioid requirements. Her opioid requirements tailed down subsequently with the successful insertion of the infraclavicular nerve catheter and she remained pain free till her death. Palliative use of nerve catheters is a safe and an effective alternative in patients with refractory cancer pain, and we describe our methods to prolong its use and minimizing its associated long-term complications.
