National Heart Center Perfusion Guidelines

To establish the first national standards and guidelines for best practice in perfusion for patients undergoing cardiothoracic surgery in Saudi Arabia. Cardiopulmonary bypass (CPB) enables complex cardiac surgeries; however, it poses risks of potential complications.

We used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to develop these guidelines and assess the certainty of evidence through a collaborative process. A panel of 16 Cardiovascu- lar perfusion experts across Saudi Arabia formulated 22 key clinical questions relevant to local practice. PubMed, Scopus, and Embase databases were searched for each question to identify relevant systematic reviews, randomized controlled trials (RCTs), non-randomized trials, post hoc analyses, and pooled analyses published from 2010 to 2024. The guideline panel voted for every question using the GRADEpro system, requiring a minimum consensus of 70% for approval.
