Prediction of Fluid Responsiveness in Children With Single Ventricle

When there are clinical signs of hypovolemia, such as hypotension in pediatric patients with single ventricle, decreased urine output or decreased central venous pressure, right upper abdomen is gently compressed for 10 seconds. Changes of blood pressure are continuously recorded during this period. About 3 min later, intravenous colloid fluid 10 mL/kg is infused for 20 min.
