Key result
Stellate ganglion blockade did not affect resting nasal mucosal blood flow but altered spontaneous oscillations and abolished the blood flow decrease normally induced by peripheral cold provocation.
Why the study?
Does stellate ganglion blockade alter nasal mucosal blood flow in patients?
Observational
Does stellate ganglion blockade alter nasal mucosal blood flow in patients?
Sympathetic neurogenic activity regulates vasomotion and cold-induced vasoconstriction in the human nasal mucosa, but basal sympathetic vasoconstrictor activity is low.

Stellate ganglion blockade leaves resting nasal mucosal flow unchanged; hypothesis-generating for sympathetic regulation of flow oscillations.
Olsson et al. (1986) conducted an observational in Undergoing stellate ganglion blockade. Stellate ganglion blockade vs. Normal physiological state (pre-blockade) was evaluated on Nasal mucosal blood flow. Stellate ganglion blockade did not affect resting nasal mucosal blood flow but altered spontaneous oscillations and abolished the blood flow decrease normally induced by peripheral cold provocation.
