  • Dr. Luke Liu, MD

    Talk: Stellate Ganglion Block for Interventional Neuroimmunology

    Dr. Luke Liu is board certified in both anesthesiology and pain management through the American Board of Anesthesiology. He received his medical degree from UCLA School of Medicine after graduating from an accelerated 7 year B.S. and M.D. program in 2004. Dr. Liu then completed his anesthesiology residency and interventional pain management fellowship at UCSF Medical Center in San Francisco. In 2016, Dr. Liu founded Neuroversion, an interventional pain management clinic, to serve the local medical community in Anchorage, Alaska.

    In the summer of 2021, Dr. Liu serendipitously discovered that long COVID patients responded favorably to one of the most common procedures in his practice, the stellate ganglion block. He subsequently published the first case report on using stellate ganglion blocks to treat long COVID, calling for more research into this therapy and highlighting dysautonomia as a possible underlying cause of long COVID in some patients.

    Having performed more than 15,000 stellate ganglion blocks for a variety of medical conditions and observed their clinical outcomes, Dr. Liu believes all complex chronic conditions have a neuroimmunological basis. He advocates for “Neuroversion” therapy, which he likens to cardioversion for the heart. He believes that modulating the affected neurological system may restore the balance to the neuroimmunological system.
