[Practical aspects of cardioplegia].

Concentrations of the ingredients have been analysed in a nonstandard cardioplegia solution (CS) and CS from St. Thomas Hospital at the outset before CS introduction into the coronary vessels of patients under cardioplegia. It has been shown that the use of nonstandard CS was accompanied by undesirable variability in ingredient concentration, which to some extent may be accounted for by the use of incompletely unfrozen CS. The use of CS from St. Thomas Hospital could be accompanied by moderate hypermagnesiumemia, which did not lead to the onset of vascular insufficiency. It is stressed that plasma magnesium content should be controlled when this CS is used.

[The Soviet colloid modegel as a component of a perfusion medium used in surgery with extracorporeal circulation].

The results of the application of a new Soviet colloid solution modegel in cardiopulmonary bypass surgery in 50 patients have been analysed. The data obtained have been compared to those of control patients who were administered gelatinol instead of modegel. Modegel ensures optimal basic plasma electrolyte content, colloid-osmotic pressure and osmolality during perfusion.

[The content of calcium and magnesium in official Soviet solutions used in extracorporeal circulation, anesthesia and resuscitation].

Total calcium (CaT) and total magnesium (MgT) levels have been determined in 21 solutions used in cardiopulmonary bypass surgery and manufactured in the USSR. It has been found that a great number of solutions differ in CaT content from human plasma. Some solutions contain Ca, which is not required by the prescription. Even in one and the same lot solutions vary greatly in Ca content (gelatinol). A large number of the solutions tested does not correspond to blood in MgT content, either. Like Ca, this parameter is quite unstable. Such differences in CaT and MgT levels practically in all standard Soviet-made solutions make it impossible to determine accurately precise amount of the solution required. The optimal way of hypercalcemia and hypermagnesiuemia prevention is the elaboration of the solutions identical to blood in their Ca and Mg content, or the use of colloids, practically free of electrolytes (hexaethyl starch).

[The concentration of calcium and its fractions during heart surgery using extracorporeal circulation].

Changes in the concentration of calcium and its fractions have been studied in 115 patients subject to standard bypass techniques. It has been found that calcium homeostasis disturbances do really develop and are caused by the use of solutions that are not balanced with blood in their calcium content. The main source of calcium in hemodiluents was gelatinol. A decrease in gelatinol volume to 450-600 ml prevented the onset of marked hypercalcemia. As ionized calcium (Ca2+) concentration is determined not only by the total Ca level, but also by the shifts in the degree of pH- and pCO2-dependent ionization and binding and in ligand and protein content, Ca2+ determination is considered an optimal method of calcium homeostasis control during cardiopulmonary bypass.
