[Use of potassium canrenoate in cardiosurgery].

The influence of canrenoate of potassium, a new injectable antialdosteronic, on serum, urinary and intraerythrocyte ionograms has been evaluated as part of a random controlled study on patients submitted to ECC heart surgery. The results show that the drug maintains correct ionic homoestasis and gradualises and potentiates diuresis, in association with furosemide. The possible clinical implications of these results are discussed.
