[Energy substrate metabolism in myocardium in the dynamics of hypothermic perfusion in combined cardioplegia in an experiment].

Experiments on 16 mongrel dogs have indicated that an anesthetic aid during cardiosurgical operations, which involves current multicomponent anesthesia, hypothermal perfusion and cardioplegia, fails to provide a complete protection of the myocardium from ischemia and a balanced uptake of energy substrates in the immediate postperfusion period.
