[Stellate ganglion block in the treatment of ischemic syndrome in an upper limb due to accidental intra-arterial injection of pharmacologic substances or narcotics].

: The paper describes five cases of accidental intraarterial injection of pharmacological drugs (diazepam or thiopentone) or dope (heroin) in an upper limb. Following a review of the physiopathological mechanisms which led to ischemic damage, the Authors outline a protocol of continuous pharmacological sympathicolysis in the affected limb, using repeated anesthetic blocks of the homolateral stellate ganglion.
