Brief summary
Goal directed therapy (GDT) utilises various monitoring techniques to assess cardiovascular performance and allows for timely interventions based on predetermined algorithms. The aim of this prospective randomised study is to evaluate the effect of GDT on major complications in children undergoing radical correction of congenital heart defects, complicated by acute heart failure. Goal directed therapy will be implemented with the aid of transpulmonary thermodilution and based on predetermined algorithms.
Interventions
Based on transpulmonary thermodilution data, the following interventions will be implemented: Global end diastolic volume (GEDV) ≤ 430 ml/m2 and extravascular water index (EVWI) ≤ 10 ml/kg: fluid load; GEDV ≥ 550 ml/m2 and EVWI ≥ 10 ml/kg: furosemide; cardiac index (CI) ≤ 2 l/min/m2 - inotropic support: * decreased heart rate (HR): dobutamine, dopamine; * normal or increased HR: epinephrine, norepinephrine; CI ≥ 2 l/min/m2 and normovolemia: phenylephrine.
