RT Journal Article SR Electronic T1 Interfascial Plane Blocks: Back to Basics JF Regional Anesthesia & Pain Medicine JO Reg Anesth Pain Med FD BMJ Publishing Group Ltd SP 341 OP 346 DO 10.1097/AAP.0000000000000750 VO 43 IS 4 A1 Hesham Elsharkawy A1 Amit Pawa A1 Edward R. Mariano YR 2018 UL http://rapm.bmj.com/content/43/4/341.abstract AB Abstract Ultrasound-guided interfascial plane blocks are a recent development in modern regional anesthesia research and practice and represent a new route of transmission for local anesthetic to various anatomic locations, but much more research is warranted. Before becoming overtaken with enthusiasm for these new techniques, a deeper understanding of fascial tissue anatomy and structure, as well as precise targets for needle placement, is required. Many factors may influence the ultimate spread and quality of resulting interfascial plane blocks, and these must be understood in order to best integrate these techniques into contemporary perioperative pain management protocols.
