A vizsgálatról

Mit akar kideríteni a vizsgálat

Malformations of the heart are common; 1.35 million infants are born each year with congenital heart disease. Many of these defects carry a considerable threat to the individual's quality of life as well as survival. Along with focused medical management, surgical repair remains a standard of care for more than 25,000 infants and children each year in the United States and Canada. The care of individuals with congenital heart disease is highly complex and has significant risks of morbidity and mortality. Most cardiac operations require the use of cardiopulmonary bypass (CPB, also known as the heart-lung machine) to safely access the inner chambers of the heart. CPB itself has been well documented to cause significant inflammation and hemodilution as the individual's blood is passed through a foreign circuit. This inflammatory response can lead to fluid overload, distributive shock and potential end-organ dysfunction in the heart, lungs, kidneys, brain, liver or bowels. These organ dysfunctions may culminate in post-operative low cardiac output syndrome (LCOS), prolonged ventilation time, prolonged intensive care unit (ICU) stay and can contribute to mortality.

Dampening the inflammatory response from CPB has been a focus of research interest for years. Intra-operative ultrafiltration has been used to remove excess fluids and filter off inflammatory cytokines during cardiac operations. Over 90% of children's heart centers in the world utilize some form of ultrafiltration (mostly some form of modified ultrafiltration), but there are wide variations in published ultrafiltration protocols (none of which are combination SBUF-SMUF in children). Ultimately, this project seeks to provide high-quality evidence that the immunologic and clinical effects of combination SBUF-SMUF are rate dependent. Therefore, a randomized study directly comparing a high-exchange SBUF-SMUF (60ml/kg/hr) and a low-exchange SBUF-SMUF (6ml/kg/hr) can identify which is the optimal ultrafiltration protocol to enhance post-operative clinical outcomes for this patient population. The expected data and results could be immediately applicable to improve recovery after heart surgery for infants and children across Canada and the rest of the world at large.
