We compared multidose crystalloid hyperkalemic cardioplegic solutions with and without added red cells in 24 canine hearts subjected to 5 hr of arrest at 10 degrees C. All cardioplegic solutions were fully oxygenated at 4 degrees C before delivery. Since blood cardioplegia contained Ca++ carried over with the red cells, Ca++ was added to the crystalloid solution in one group. The table below shows the hematocrit (HCT) and ionized Ca++ concentrations of the cardioplegic solutions, and coronary… CONTINUE READING
