Brief Summary:
First we the researchers hope to find out the PCT response to heart surgery in children by taking blood before surgery and each day for four days after surgery These blood draws will help us figure out the typical Procalcitonin PCT response the normal increase in PCT after heart surgery and when the PCT level returns to baseline
Second we the researchers hope to determine the accuracy of PCT as a marker of infection
Hypothesis
Our hypothesis is that Procalcitonin is superior to other currently used markers of infection and will prove to be a clinically useful tool for evaluation of infection in children following cardiac surgery

Detailed Description:
In this research study we want to look at the difficulty in identifying infections in children who have heart surgery We also want to look at differentiating between actual infections and the normal post-surgery course that patients go through We use a number of tools in the Intensive Care Unit to pick out children at risk for an infection These tools are the physical examination a fever white blood cell count and C-reactive Protein CRP level When a patient has an infection they usually have a fever have a high white blood cell count and have an increased CRP level However these are not always correct The identification of infection remains a challenge and the laboratory markers of infection white blood cell count and CRP that are used now are not perfect
A new marker of infection Procalcitonin PCT has been found and has been tested in adults and children PCT has recently been approved by the Food and Drug Administration FDA as a marker of infection PCT has been shown to be a more accurate marker of infection for some groups of patients
Prior work on a small number of children shows that PCT increases shortly just from heart surgery itself even without infection There is little information published about how accurate PCT is for identifying infection in the child heart population In order to use PCT in our patients we need to know what the normal levels of PCT are after surgery Thus when an infection does happen we can identify it We also need to take PCT levels when patients are thought to have infections We will then need to watch for an infection over the next few days to see if the PCT level rises and can actually predict the presence an infection
Goals
1 Determine the Procalcitonin response to cardiopulmonary bypass in children undergoing open-heart surgery Cardiopulmonary bypass causes a pro-inflammatory state in the patient and associated rise in Procalcitonin The ability to use PCT as a marker for infection will require knowledge of its typical response to bypass and the time course to return to baseline
2 Determine the accuracy of Procalcitonin as a marker of infection and to compare and contrast these findings with currently used laboratory markers
Specific Aims
1 Evaluate PCT in the postoperative pediatric cardiac surgical patient as a marker for infection and sepsis
2 Evaluate PCTs response to cardiopulmonary bypass and as a predictor of outcome following cardiac surgery
3 Compare PCT to other markers of inflammation and infection C-reactive protein and white blood cell response
By doing this study we hope to find out two things First we hope to find out the PCT response to heart surgery in children by taking blood before surgery and each day for four days after surgery These blood draws will help us figure out the typical PCT response the normal increase in PCT after heart surgery and when the PCT level returns to baseline
Second we hope to determine the accuracy of PCT as a marker of infection Whenever we think a patient may have an infection it is routine care to take some blood and run lab tests such as a white blood cell count blood culture and a C-reactive protein level Patients in the study will also have an additional 10 drops of blood taken for a PCT level at the same time as the routine blood draw Even though patients may show signs of an infection the routine blood test do not always come back positive for an infection We will compare the routine blood test results positive or negative for an infection with the PCT level taken at the same time If most patients with an infection also have a rise in PCT and those patients without an infection have a normal PCT then we will prove that PCT is a good accurate marker for infection in our patients
This research will help us study infection in our patients It will help distinguish patients with infection what the risk factors are how they are treated and the response to infection This information will potentially allow us to use an improved test for identifying infection in a high-risk population of children Patients in the research project will continue to receive the standard of care treatment after heart surgery and there will be no changes in their care during the study
