Effects on hemodynamic variables and echocardiographic parameters after a stellate ganglion block in 15 healthy volunteers.

Background: The sympathetic nervous system has an important role in generating pain. Various pathomechanisms are involved that respond well to the application of local anesthetics (LA), for example to the stellate ganglion block (SGB).

Objectives: We wanted to know more about the effects of SGB on cardiovascular parameters.
