Portable ultrasound is a promising imaging modality used in interventional pain management. It allows the identification of soft tissues, vessels, and nerves, without exposing patients and personnel to radiation. Imaging is performed continuously and the fluid injected is visualized in a real-time fashion.
Possible applications using portable ultrasound include nerve blocks of the cervical and lumbar zygapophysial joints, blocks of painful stump neuromas, stellate ganglion block, intercostal nerve blocks, peripheral nerve blocks of the extremities, caudal epidural injections, and injections of tender points.
