The relative buffering power of cardioplegic solutions.
Those factors that prolong myocardial tolerance to global ischemia constitute an important prerequisite for effective cardioplegia. This study contrasts the relative buffering power of bicarbonate-based and tromethamine-based hyperkalemic crystalloid cardioplegic solution with histidine protein-type buffer (Bretschneider) solution. In addition, the solutions were compared with titration of whole blood and myocardial muscle homogenate.
