RT Journal Article SR Electronic T1 Ultrasound Guidance for Ulnar Nerve Block in the Forearm JF Regional Anesthesia & Pain Medicine JO Reg Anesth Pain Med FD BMJ Publishing Group Ltd SP 335 OP 339 DO 10.1016/S1098-7339(03)00196-2 VO 28 IS 4 A1 Andrew T. Gray A1 Ingeborg Schafhalter-Zoppoth YR 2003 UL http://rapm.bmj.com/content/28/4/335.abstract AB Objective The objective of this study was to establish the feasibility of ulnar nerve block under direct imaging.Case reports Two patients undergoing surgery on the fifth digit or medial hand received ulnar nerve blocks in the mid-forearm (approximately 15 cm proximal to the styloid process of the ulna). Ultrasound imaging was used to identify the ulnar nerve in the forearm and guide local anesthetic infiltration. Both patients had successful blocks, including sensory anesthesia of the dorsomedial hand.Conclusions Ultrasound guidance for ulnar nerve block in the forearm is a promising technique that includes block of the dorsal cutaneous branch. Anatomic and sonographic considerations are discussed.
