[Three case reports of the use of stellate ganglion block for the climacteric psychosis].

There are many reports of the use of stellate ganglion block (SGB) for the climacteric psychosis, which is considered to be sympathicotonic response to stress. We experienced three cases of the SGB therapy for the climacteric psychosis. We performed SGB three times per week by 1% lidocaine 5 ml, and observed improvements of the symptoms after doing SGB for five times. The patients reported psychological relaxation after receiving SGB therapy. We examined the changes of the serum concentrations of ACTH, LH, FSH, and catecholamines (epinephrine, norepinephrine) before and after SGB in 8 patients who were suffering from climacteric psychosis, because we wanted to know the endocrinological response to SGB. We observed a significant decrease in norepinephrine concentration after SGB, which is reasonable considering the sympathetic blockage. There were no significant changes of ACTH, LH, FSH, and epinephrine. We conclude that SGB therapy must be effective for the climacteric psychosis because of sympathetic blockade. But we could not clarify the influence of endocrinological response to SGB.
