The Use of Hemostatic Blood Products in Children Following Cardiopulmonary Bypass and Associated Outcomes.

To describe the use of hemostatic transfusions in children following cardiac surgery with cardiopulmonary bypass and the association of hemostatic transfusions postoperatively with clinical outcomes. DESIGN: A retrospective cohort study. SETTING: PICU of a tertiary care center from 2011 to 2017. PATIENTS: Children 0-18 years old undergoing cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Four-hundred twenty children underwent cardiac surgery with cardiopulmonary bypass. The median (interquartile range) age was 0.8 years (0.3-5 yr) and 243 (58%) were male. The majority of cases were classified as Risk Adjustment for Congenital Heart Surgery 2 (223, 54%) or Risk Adjustment for Congenital Heart Surgery 3 (124, 30%). Twenty-four percent of children (102/420) received at least one hemostatic transfusion with the most common first product being platelet transfusions (47/102), followed by plasma (44/102), and cryoprecipitate (11/102). The children who received hemostatic transfusions were younger (p = 0.006), had lower body weights (p = 0.004), less likely to be their initial operation with cardiopulmonary bypass (p = 0.003), underwent more complex surgeries (p = 0.001) with longer bypass runs (p < 0.001), and had more use of hypothermic circulatory arrest (p = 0.014). The receipt of hemostatic blood products postoperatively was independently associated with more days of mechanical ventilation (p < 0.001) and longer PICU lengths of stay (p = 0.001) but not with time receiving vasoactive mediations (p = 0.113) or nosocomial infections (p = 0.299). CONCLUSIONS: Nearly one-quarter of children undergoing cardiac repair with cardiopulmonary bypass receive hemostatic transfusions postoperatively. These blood products are independently associated with worse clinical outcomes. Larger studies should be performed to determine the hemostatic efficacy of these products, as well as to clarify associated morbidities, in order to inform proper blood management.

COVID-19 Inflammatory Syndrome With Clinical Features Resembling Kawasaki Disease.

We describe 2 patients with coronavirus disease who had multiple clinical features suggestive of Kawasaki disease (KD). Both patients presented with fever lasting >5 days and were found to have rash, conjunctival injection, and swollen lips. One patient also had extremity swelling, whereas the other developed desquamation of the fingers. In both cases, laboratory results were similar to those seen in KD. These patients had highly unusual but similar features, and both appeared to respond favorably to treatment. It remains unclear whether these patients had true KD or manifestations of coronavirus disease that resembled KD.
