RT Journal Article SR Electronic T1 Images in anesthesiology: three safe, simple, and inexpensive methods to administer the sphenopalatine ganglion block JF Regional Anesthesia & Pain Medicine JO Reg Anesth Pain Med FD BMJ Publishing Group Ltd SP rapm-2020-101765 DO 10.1136/rapm-2020-101765 A1 Danielle Levin A1 Shaul Cohen YR 2020 UL http://rapm.bmj.com/content/early/2020/08/10/rapm-2020-101765.abstract AB The sphenopalatine ganglion (SPG) block is a simple and valuable technique that was discovered over a century ago, but, unfortunately, very few anesthesiology providers are familiar with this block. After some of our recent publications, physicians from different countries have reached out to us requesting more specifics on how we perform our version of the block. In this report, we provide a brief history of the block and demonstrate our three effective, simple, readily available, and inexpensive methodologies with images. We are proud to share that our three SPG block techniques have so far effectively relieved patients of chronic migraines, acute migraines, tension headaches, moderate-to-severe back pain, and post-dural puncture headaches.
