Lidocaine is frequently in the "cocktail" when you undergo Stellate ganglion blocks. http://www.rsdrx.com/rsdpuz4.0/puz_41.htm

I do know that when Carden does SGB, he does them via fluoroscopy which is ESSENTIAL IMO. If I were in the early stages, I would fight for blocks AND Ketamine.

After undergoing a SGB have a very gentle massage performed asap!!! http://www.rsdrx.com/massage_therapy.htm
