i have stellate blocks once a week and have never had lead. my doc does use floro. the nurses and the doc always wear lead but they do so because they are in the room around the x ray radiation for hours (my mom is an iv sedation nurse).
in all of my sgb i have had the red flush thing once...the doc tried a different mix of meds and i was allergic to one of them. i took some benadryl and the itchiness and redness subsided, the next block we went back to the old mix.
i hope things work out
