[Hormonal changes during electrocoagulation of the Gasserian ganglion under neuroleptanalgesia and the effects of administration of a beta blocking agent (author's transl)].

Hormonal changes, occurring during electrocoagulation of the Gasserian ganglion under neuroleptanalgesia, and the effects of intravenous administration of pindolol 0.4 mg on these changes were investigated in two groups of 10 and 12 patients of advanced age. At the end of the operation there were marked increases of the concentrations of catecholamines, a rise of the plasma cortisol and a fall of the serum insulin. The administration of the beta-adrenergic blocking agent did not induce any statistically significant changes of the determined hormones compared to the control group.
