RESUMO

Care and outcomes for the more than 40,000 patients undergoing pediatric and congenital heart surgery in the United States annually are known to vary widely. While consensus recommendations have been published across numerous fields as one mechanism to promote a high level of care delivery across centers, it has been more than two decades since the last pediatric heart surgery recommendations were published in the United States. More recent guidance is lacking, and collaborative efforts involving the many disciplines engaged in caring for these children have not been undertaken to date. The present initiative brings together professional societies spanning numerous care domains and congenital cardiac surgeons, pediatric cardiologists, nursing, and other healthcare professionals from diverse programs around the country to develop consensus recommendations for United States centers. The focus of this initial work is on pediatric heart surgery, and it is recommended that future efforts focus in detail on the adult congenital population. We describe the background, rationale, and methodology related to this collaborative effort, and recommendations put forth for Essential Care Centers (essential services necessary for any program), and Comprehensive Care Centers (services to optimize comprehensive and high-complexity care), encompassing structure, process, and outcome metrics across 14 domains.

RESUMO

BACKGROUND: Myocardial ischemia and reperfusion (I/R) injury causes significant morbidity and mortality. Protection against I/R injury may occur via preservation of tissue metabolism and ATP content, preservation of reduced glutathione, and stimulation of heat shock protein (HSP) synthesis. Supplementation with glutamine (GLN) has been reported to have beneficial effects on all of these protective pathways. Thus, we hypothesized that GLN pretreatment given to the rat in vivo would protect the myocardium against I/R-induced dysfunction. METHODS: GLN (0.52 g/kg, intraperitoneally, given as alanine-glutamine dipeptide), alanine alone (0.23 g/kg), or a Ringer's lactate solution (control) was administered to Sprague-Dawley rats 18 hours before heart excision, perfusion, exposure to global ischemia (15 minutes) and reperfusion (1 hour). Tissue metabolites were analyzed via magnetic resonance spectroscopy. RESULTS: In control and alanine-treated animals, I/R injury resulted in cardiac dysfunction, indicated by a decrease in cardiac output. Administration of GLN 18 hours before I/R injury preserved cardiac output after reperfusion. Metabolic analysis of the myocardial tissue revealed that [/R injury led to significant diminution of myocardial tissue glutamate, ATP content, accumulation of myocardial lactate, and a reduction in reduced glutathione content in control animals. GLN significantly reduced the deleterious changes in myocardial metabolism and improved reduced glutathione content. No changes in pre- or post-I/R injury HSP expression were observed after GLN administration. CONCLUSIONS: These observations demonstrate that remote in vivo administration of GLN before cardiac I/R injury can improve post-I/R cardiac function. This effect may be mediated via improved myocardial metabolism and enhanced reduced glutathione content.
