After heart surgery, children in intensive care sometimes need extra fluids to help their body deliver oxygen properly. This study is testing whether a simple blood marker — called the Pv-aCO2/DAVO2 ratio — can predict which children will actually benefit from these fluids. Researchers will measure this marker and oxygen levels before and after fluid treatment to see if it helps doctors make better decisions.
Doctors know that giving extra fluids helps some children recover better after heart surgery, but too much fluid can cause harm. Right now, there's no reliable way to know in advance which child will actually benefit. This research aims to solve that problem by finding a blood test that predicts whether a child's body will truly use the extra fluid to improve oxygen delivery.

If your child is enrolled, their doctors will draw blood samples before and within one hour after giving the planned fluid treatment — tests they would likely do anyway as part of routine care. During this time, they will also have an ultrasound of the heart to measure how well it's pumping. The study is purely observational, meaning no new medications or procedures are added; researchers are simply looking at routine medical information to see if the blood marker can predict who benefits from fluids.
