Study Summary
Newborn babies and children with congenital heart defects who need heart surgery need to be placed on the heart-lung machine for heart surgery. In order to use the heart-lung machine, the investigators have to use blood and other fluids to fill the tubing. During the operation, ultrafiltration is carried out as standard of care to remove extra fluid. Modified ultrafiltration is also performed after surgery. In this study, the investigators are looking to use the filter additionally before surgery. Using the pre bypass filtration before the subject is placed on the heart-lung machine will allow the investigators to better normalize electrolytes in the blood/fluid mixture used in the heart lung machine. This technique is called pre-bypass ultrafiltration, or PBUF (pronounced "P" Buff). The investigators are conducting a study to see if using PBUF to better normalize electrolytes in the blood will make a difference. The investigators have been adding fluids to prime the heart-lung machine in two different ways. The investigators believe both methods are safe and acceptable but hypothesize that there may be subtle differences in electrolytes and fluid status when one technique is used as opposed to the other. The investigators believe that neither technique introduces risk since both are currently used in practice. The standard method adds blood to the heart-lung machine. The alternate method adds blood to the heart-lung machine and then additional fluid is added and removed to more normalize the electrolytes. The investigators plan to randomized subjects undergoing heart surgery to receive the standard priming method versus PBUF to determine if there is any difference in outcomes. Laboratory and clinical data collected as part of clinical care will be used to determine difference sin outcomes. There will be no additional blood taken for this study. There are no known risks to PBUF. The benefits include helping investigators determine if PBUF does or does not make a
Primary Outcome
Differences in glucose (mg/dl) at the following time points, and also differences in the percentage of values within the normal range for each time point, for PBUF versus standard care. 1. Final prime value (in the PBUF group after completion of PBUF and prior to cardio pulmonary bypass (CPB), in the control group prior to CPB) 2. First measured levels on bypass - typically 10 minutes post initiation of bypass 3. Last value on CPB 4. Last value in OR 5. First arrival to ICU
Interventions
- OTHER Use of prebypass ultrafiltration (PBUF)
