Dysmenorrhea(cyclic pain associated with menses) is a frequent disorder, with as many as 50% of young women experiencing the symptom, and up to 10% being unable to function normally for some time each month. The most recent theory of the cause of the pain of dysmenorrhea incriminates uterine ischemia and sensitization of uterine pain fibers resulting from excessive myometrial contractility after prostaglandin stimulation. We administered stellate ganglion block for the treatment of dysmenorrhea and had good results in two cases. From our experience, we recommend the stellate ganglion block may be an effective treatment for a dysmenorrhea.
