Background: Pediatric cardiac surgery is associated with abnormal coagulation, bleeding, and nearly ubiquitous transfusions. With the popularization of patient blood management, attempts are being made to decrease liberal transfusions by administering prothrombin complex concentrates (PCCs). The safety and efficacy of PCCs in adult cardiac surgery has been studied extensively, but only few reports address this in children. We performed an observational study focused on transfusion requirements after off-label use of activated PCC Factor Eight Inhibitor Bypassing Activity (FEIBA) as an adjunct to post-cardiopulmonary bypass (CPB) hemostatic protocol., Methods: We reviewed the medical records of children ≤15 kg undergoing cardiac operations with CPB between May 2018 and March 2022. A propensity score (PS) analysis was performed to identify matched pairs of patients who did and did not receive FEIBA., Results: Out of 210 patients who met the inclusion criteria, 44 patients received FEIBA. Propensity score-based analysis identified 40 matched pairs of patients with similar baseline characteristics. There was no statistically significant difference in the primary outcome-the volume of transfusion after CPB, which included all allogeneic blood products and salvaged washed red cells administered after protamine. Specifically, FEIBA patients were transfused 28 (22-34) mL/kg and controls were transfused 22 (11-49) mL/kg, P  = .989. Upon arrival to ICU, the FEIBA group averaged an 8% lower international normalized ratio, compared with the controls ( P  = .009) and a 1.08 g/dL higher hemoglobin ( P  = .050). Neither difference remained significant on POD 1., Conclusions: In this exploratory study, we found no change in transfusion requirements after CPB despite FEIBA administration.

Objective: No risk prediction model is currently available to measure patient's probability for readmission to the pediatric intensive care unit (PICU). This retrospective case-control study was designed to assess the applicability of an adult risk prediction score (Stability and Workload Index for Transfer [SWIFT]) and to create a pediatric version (PRediction Of PICU Early Readmissions [PROPER])., Design: Eighty-six unplanned early (<48 hours) PICU readmissions from January 07, 2007, to June 30, 2014, were compared with 170 random controls. Patient- and disease-specific data and PICU workload factors were compared across the 2 groups. Factors statistically significant on multivariate analysis were included in the creation of the risk prediction model. The SWIFT scores were calculated for cases and controls and compared for validation., Results: Readmitted patients were younger, weighed less, and were more likely to be admitted from the emergency department. There were no differences in gender, race, or admission Pediatric Index of Mortality scores. A higher proportion of patients in the readmission group had a Pediatric Cerebral Performance Category in the moderate to severe disability category. Cases and controls did not differ with respect to staff workload at discharge or discharge day of the week; there was a much higher proportion of patients on supplemental oxygen in the readmission group. Only 2 of 5 categories in the SWIFT model were significantly different, and although the median SWIFT score was significantly higher in the readmissions group, the model discriminated poorly between cases and controls (area under the curve: 0.613). A 7-category PROPER score was created based on a multiple logistic regression model. Sensitivity of this model (score ≥12) for the detection of readmission was 81% with a positive predictive value of 0.50., Conclusion: We have created a preliminary model for predicting patients at risk of early readmissions to the PICU from the hospital floor. The SWIFT score is not applicable for predicting the risk for pediatric population.
