title: [Antidiuretic hormone, the renin-angiotensin system and anesthesia].
abstract: The authors, on the basis of the literature and their own studies, envisage the behaviour of the renin-angiotensin system and of ADH during anesthesia. With regard to renin-angiotensin, it would seem that the changes reported in the past are due to the surgical procedure itself or result form haemodynamic changes but that no anesthetic has a direct effect upon the secretion of renin. For ADH, three concepts must be borne in mind: not only is secretion not influenced by anesthetics, but on the contrary anaesthesia decreases the "vasopressin" response to surgical stress. By contrast, the surgical procedure may induce the secretion of ADH responsible for coronary vasoconstriction. Finally, at high doses, ADH would appear to have an inverse antinatriuretic effect resulting in a sodium diuresis.
