Published in: Current pain and headache reports (2022)
In a MEDLINE/Pubmed search of ultrasound-guided peripheral nerve blocks and peripheral nerve catheters for specific anatomic targets, a total of 28 case reports and case series were identified. Included studies described improved analgesia and reduced opioid requirements with highly variable duration of effect. Current level of evidence remains limited. Pain is a symptom that markedly impacts the quality of life of cancer patients and ultrasound-guided regional techniques are a promising therapeutic option albeit with a limited evidence base. Practical recommendations offered for coordinating access to such therapies in the inpatient, emergency department, and outpatient settings may expand interest and facilitate higher quality research.
