Stellate ganglion blockade provides relief from menopausal hot flashes: a case report series.
OBJECTIVE: To investigate whether standard C6 stellate ganglion blockade (SGB) might provide relief from hot flashes associated with menopause. METHODS: Six women were referred for severe menopausal hot flashes and elected to undergo standard SGB (5 ml 0.375% Marcaine, Abbott Labs, Abbott Park, IL) to evaluate a novel intervention for hot flash relief. Hot flashes were assessed by self-reporting before and after stellate ganglion block. RESULTS: Initial SGB (SGB1) was successful in all 6 subjects, as evidenced by a positive Horner's syndrome and anhydrosis. Successful SGB caused complete alleviation of hot flashes for times ranging from 2 to 5 weeks. Patients returned for follow-up SGB after mild hot flashes returned. A second SGB produced additional asymptomatic periods of relief ranging from 4 to 18 weeks. In each case, repeated block provided hot flash relief equal to or greater than that of the initial block. Two patients who submitted for a third SGB reported 15 and 48 weeks of relief. CONCLUSION: Successful SGB appears to be related to relief of hot flashes. Repeat SGB results in efficacious multiple week relief of severe hot flashes associated with menopause.[1]References
