Key result
Stellate ganglion block did not clinically increase blood pressure and heart rate, though hoarseness occurred more frequently in patients with a >20% increase in blood pressure (P=0.02).

Supports stellate ganglion block hemodynamic safety in stable patients; leaves open hoarseness relevance and randomized confirmation.
Observational (n=26)
Does stellate ganglion block alter blood pressure, heart rate, and heart rate variability in normal hemodynamic patients?
Stellate ganglion block does not cause clinically significant increases in blood pressure or heart rate in hemodynamically normal patients.
Kweon et al. (2006) conducted an observational in Patients undergoing stellate ganglion block (n=26). Stellate ganglion block vs. Baseline was evaluated on Changes in blood pressure, heart rate, and heart rate variability. Stellate ganglion block did not clinically increase blood pressure and heart rate, though hoarseness occurred more frequently in patients with a >20% increase in blood pressure (P=0.02).
