There was compared the occurrence frequency of the acute cardiac insufficiency, acute myocardium infarction, acute disorder of cerebral blood circulation, disorders of cardiac rhythm and conduction and other perioperative complications in patients of three groups, operated on using artificial blood circulation, in whom the cardioplegic solution, prepared according to different methods, was used. It is recommended not to permit the crystallization (freezing) of isotonic sodium chloride solution occurrence, used for cardioplegia and for flooding to the pericardium cavity also to cool the heart externally.

One hundred and thirty five children have been examined after surgery for congenital heart valve defects performed under ketamine anesthesia. It has been established that ketamine anesthesia has no considerable effect on the preload and cardiac pump function. Different hemodynamic changes have been observed in systemic and pulmonary circulation: the afterload of the left ventricle increases, while the afterload of the right ventricle decreases, which causes an increase in the heart performance (and energy consumption) in the first case and their reduction in the second case.

It has been shown that N2O has distinct effect on oxidation-phosphorylation in mitochondria of the above organs. The most marked changes were observed in the myocardium and liver.

Patients with congenital heart valve defects under calipsol anesthesia reveal different hemodynamic changes in systemic and pulmonary circulation; left ventricular afterload is increased, which leads to an enhancement in left ventricular work. The type of general anesthesia under study decreases right ventricular afterload and right ventricular work.
