Brief summary
Extracorporeal membrane oxygenation (ECMO) is a form of heart-lung bypass used to support children who suffer heart or lung failure until whatever illness caused that failure can be treated and reversed. While on ECMO, children are at increased risk of infection, including fungal infection. Treatment for fungal infection includes not only antifungal medications but also removal of any large intravenous (IV) lines. Since ECMO requires large IV lines, proper treatment of fungal infections would be difficult if not impossible. The investigators believe that giving prophylactic antifungal medication to all children on ECMO may prevent fungal infections from developing in the first place. Fluconazole is an antifungal medication that works well against the most common fungal infections and has been shown to be safe in children. Unfortunately, the ECMO machine has the potential to significantly alter the drug levels of medications so the investigators do not know the proper dose of Fluconazole to give children on ECMO. Standard dosing of fluconazole is 12mg per kilogram of body weight given intravenously once daily. Based on preliminary data and modeling from other studies, the investigators think 25mg per kilogram given once weekly will achieve proper drug levels to prevent fungal infections. The investigators have obtained FDA approval to give this dose of fluconazole to children on ECMO who are enrolled in the study. Blood samples will be collected at specific times around the first and second fluconazole doses to describe the PK and drug extraction by the ECMO circuit.
