# Eugene Lipov

Eugene G. Lipov, M.D. (born 1958) is a physician researcher and board-certified anesthesiologist who specializes in intervention-based pain management in the Chicago area.He is best known for his treatment of post-traumatic stress disorder (PTSD) using the stellate ganglion block (SGB). The injection-based technique "seems to 'reboot' the body's sympathetic system and may help to reset a PTSD patient's overreaction to stimuli — their 'fight or flight' response—by resetting the sympathetic nervous system and central nervous system to the pre trauma state..In 2016, the Pentagon approved funding for a study at three Army medical centers, citing SGB’s potential to be a huge game changer for many affected people with PTSD, whether from combat, sexual assault or other trauma. In 2017, the U.S. Army commissioned the first large-scale randomized trial of the procedure.Published in 2019, an Army-funded study, conducted by RTI International, confirmed that SGB was more than two times as effective compared to a placebo in relieving PTSD symptoms.
