Abstract

Background Cardioplegia is an integral part of myocardial protection. The superiority of blood cardioplegia in adult patients has been reported. However, this is yet to be studied in cyanotic pediatric patients. Methods A randomized open-label trial was conducted in 70 patients with tetralogy of Fallot. They were divided into two groups: 35 patients had crystalloid cardioplegia (controls), and 35 had blood cardioplegia. Lactate and coronary oxygen extraction in arterial blood and the coronary sinus were measured immediately after cessation of cardiopulmonary bypass, 15 and 30 min later. Postoperative mortality, major adverse cardiac events, mechanical ventilation time, inotrope administration, arrhythmias, right ventricular function, intensive care unit and hospital length of stay were observed. Results There were no significant differences in clinical outcomes or lactate levels. There was a significant difference in coronary oxygen extraction immediately and 15 min after cessation of cardiopulmonary bypass ( p = 0.038, p = 0.015). Conclusion Blood cardioplegia gave a better postoperative oxygen extraction value but there were no differences in myocardial damage or clinical outcome between the two groups.
