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

Objectives

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.

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.
