Rationale for Implementation of Warm Cardiac Surgery in Pediatrics.

Cardiac surgery was developed thanks to the introduction of hypothermia and cardiopulmonary bypass in the early 1950s. The deep hypothermia protective effect has been essential to circulatory arrest complex cases repair. During the early times of open-heart surgery, a major concern was to decrease mortality and to improve short-term outcomes.

Is there a rationale for short cardioplegia re-dosing intervals?

While cardioplegia has been used on millions of patients during the last decades, the debate over the best technique is still going on. Cardioplegia is not only meant to provide a non-contracting heart and a field without blood, thus avoiding the risk of gas emboli, but also used for myocardial protection. Its electromechanical effect is easily confirmed through direct vision of the heart and continuous electrocardiogram monitoring, but there is no consensus on the best way to assess the quality of myocardial protection.

Use of blood products in pediatric cardiac surgery.

In pediatric cardiac surgery, there is a substantial gap between published recommendations or guidelines for blood product use and clinical practice. The drawbacks of blood transfusion are well acknowledged though. The aim of this paper is to present the rationale for packed red blood cells, fresh frozen plasma (FFP), and platelets used in pediatric patients.
