In 10 patients undergoing routine coronary artery surgery, plasma renin activity and vasopressin concentration were measured at intervals before the induction of anaesthesia, and for 6 h after bypass. In three patients plasma renin activity was increased, but the increases followed no particular pattern. Vasopressin concentrations increased in all 10 patients, but the changes were not significantly correlated with the postoperative arterial hypertension that was seen in seven of the patients. |
