[A multicenter study of cardiac events and anesthetic management of patients with ischemic heart diseases for noncardiac surgery--a follow-up report].

We have conducted a joint research project to investigate the incidence of ischemic heart disease in patients for noncardiac surgery and to define the risk of perioperative cardiac complications in these patients. From September to November 1997 we had 7288 patients scheduled to undergo noncardiac surgery in the 8 departments of anesthesiology. Of these patients, 228 (3.1%) patients had ischemic heart disease, and 30 of them (13.2%) developed perioperative cardiac events. Critical cardiac events, including perioperative myocardial ischemia and lethal arrhythmia, occurred in 7 of these patients. In our region of Japan, 3-4% of surgical patients tend to develop ischemic heart disease and 3.1% of them demonstrated severe cardiac complications perioperatively. Compared with United States we encounter fewer surgical patients with ischemic heart disease, but the risk of developing perioperative cardiac complications in such patients is almost the same for both countries.

[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.
