Evaluation of Clinical Impact of the Type of Cardioplegia Used in the Patient Undergoing Major Cardiac Surgery.

Myocardial protection by administering cardioplegia is a fundamental concept during cardiopulmonary bypass in patients undergoing cardiac surgery. It is a multifactorial strategy, in which cardioplegia is the most important. To date, there is no standardized consensus on the use of cardioplegia in different cardiac surgery procedures, and the best strategy continues to be debated given the wide range available. The choice of the type of cardioplegia should be made on an individual basis, taking into account the surgical procedure and clinical context. The need for a single dose of cardioplegia could favor the use of Custodiol crystaloid cardioplegia in complex cardiac surgeries that require longer extracorporeal circulation time. Both cardioplegia are safe and effective and widely used globally; however, the information provided in the literature is limited, with most of the information coming from retrospective studies.The objective of the present study is to demonstrate the non-inferiority of Custodiol crystalloid cardioplegia versus Buckberg blood cardioplegia in patients undergoing major cardiac surgery with extracorporeal circulation with prolonged aortic clamping times.
