Visibility of ultrasound-guided echogenic needle and its potential in clinical delivery of regional anesthesia.
Ultrasound-guided regional anesthesia is recommended for nerve block due to its safety and reliability. Needle visualization is important when inserting needles into tissues in close proximity to target nerves. For safety reasons, the tip of the standard-type needle for application of nerve block is thinner than that of an interventional needle for insertion into intra-abdominal organs, and this makes it harder to determine its precise position. The purpose of this study was to evaluate the performance of an insulated echogenic needle under ultrasound guidance in phantoms and in the routine anesthetic management of patients undergoing elective surgery. ⋯ The better visibility of the tip of CCR indicates that it is superior to S in the clinical delivery of peripheral nerve block.
