Plasma ionized calcium has been measured in eighteen patients undergoing open heart surgery. No change in ionized calcium concentration was found during the period of cardiopulmonary bypass. In the early postbypass period, a wide range of ionized calcium concentrations was found, but this did not obviously affect myocardial performance. Factors influencing the ionized calcium concentration under these circumstances are discussed.
已对18例接受心脏直视手术的患者测量了血浆离子钙。在体外循环期间未发现离子钙浓度有变化。在体外循环后的早期，发现离子钙浓度范围很广，但这并未明显影响心肌功能。讨论了在这些情况下影响离子钙浓度的因素。
