Objectives: Critically ill children frequently receive plasma and platelet transfusions. We sought to determine evidence-based recommendations, and when evidence was insufficient, we developed expert-based consensus statements about decision-making for plasma and platelet transfusions in critically ill pediatric patients., Design: Systematic review and consensus conference series involving multidisciplinary international experts in hemostasis, and plasma/platelet transfusion in critically ill infants and children (Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding [TAXI-CAB])., Setting: Not applicable., Patients: Children admitted to a PICU at risk of bleeding and receipt of plasma and/or platelet transfusions., Interventions: None., Measurements and Main Results: A panel of 29 experts in methodology, transfusion, and implementation science from five countries and nine pediatric subspecialties completed a systematic review and participated in a virtual consensus conference series to develop recommendations. The search included MEDLINE, EMBASE, and Cochrane Library databases, from inception to December 2020, using a combination of subject heading terms and text words for concepts of plasma and platelet transfusion in critically ill children. Four graded recommendations and 49 consensus expert statements were developed using modified Research and Development/UCLA and Grading of Recommendations, Assessment, Development, and Evaluation methodology. We focused on eight subpopulations of critical illness (1, severe trauma, intracranial hemorrhage, or traumatic brain injury; 2, cardiopulmonary bypass surgery; 3, extracorporeal membrane oxygenation; 4, oncologic diagnosis or hematopoietic stem cell transplantation; 5, acute liver failure or liver transplantation; 6, noncardiac surgery; 7, invasive procedures outside the operating room; 8, sepsis and/or disseminated intravascular coagulation) as well as laboratory assays and selection/processing of plasma and platelet components. In total, we came to consensus on four recommendations, five good practice statements, and 44 consensus-based statements. These results were further developed into consensus-based clinical decision trees for plasma and platelet transfusion in critically ill pediatric patients., Conclusions: The TAXI-CAB program provides expert-based consensus for pediatric intensivists for the administration of plasma and/or platelet transfusions in critically ill pediatric patients.

Objectives: To present consensus statements and supporting literature for plasma and platelet transfusions in critically ill children following noncardiac surgery and critically ill children undergoing invasive procedures outside the operating room from the Transfusion and Anemia EXpertise Initiative - Control/Avoidance of Bleeding., Design: Systematic review and consensus conference of international, multidisciplinary experts in platelet and plasma transfusion management of critically ill children., Setting: Not applicable., Patients: Critically ill children undergoing invasive procedures outside of the operating room or noncardiac surgery., Interventions: None., Measurements and Main Results: A panel of 10 experts developed evidence-based and, when evidence was insufficient, expert-based statements for plasma and platelet transfusions in critically ill children following noncardiac surgery or undergoing invasive procedures outside of the operating room. These statements were reviewed and ratified by the 29 Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding experts. A systematic review was conducted using MEDLINE, EMBASE, and Cochrane Library databases, from inception to December 2020. Consensus was obtained using the Research and Development/University of California, Los Angeles Appropriateness Method. Results were summarized using the Grading of Recommendations Assessment, Development, and Evaluation method. We developed eight expert consensus statements focused on the critically ill child following noncardiac surgery and 10 expert consensus statements on the critically ill child undergoing invasive procedures outside the operating room., Conclusions: Evidence regarding plasma and platelet transfusion in critically ill children in this area is very limited. The Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding Consensus Conference developed 18 pediatric specific consensus statements regarding plasma and platelet transfusion management in these critically ill pediatric populations., Competing Interests: Dr. Crighton disclosed that she is employed by Royal Children’s Hospital of Melbourne, Australia, and that she was the Australian and New Zealand Society of Blood Transfusion President. Drs. Russel and Nellis received support for article research from the National Institutes of Health. Dr. Haas received funding from Octapharma.

Objectives: To present a list of high-priority research initiatives for the study of plasma and platelet transfusions in critically ill children from the Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding., Design: Systematic review and consensus conference of international, multidisciplinary experts in platelet and plasma transfusion management of critically ill children., Setting: Not applicable., Patients: Critically ill pediatric patients at risk of bleeding and receiving plasma and/or platelet transfusions., Interventions: None., Measurements and Main Results: A panel of 13 experts developed research priorities for the study of plasma and platelet transfusions in critically ill children which were reviewed and ratified by the 29 Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding experts. The specific priorities focused on the following subpopulations: severe trauma, traumatic brain injury, intracranial hemorrhage, cardiopulmonary bypass surgery, extracorporeal membrane oxygenation, oncologic diagnosis or stem cell transplantation, acute liver failure and/or liver transplantation, noncardiac surgery, invasive procedures outside of the operating room, and sepsis and/or disseminated intravascular coagulation. In addition, tests to guide plasma and platelet transfusion, as well as component selection and processing, were addressed. We developed four general overarching themes and 14 specific research priorities using modified Research and Development/University of California, Los Angeles methodology., Conclusions: Studies are needed to focus on the efficacy/harm, dosing, timing, and outcomes of critically ill children who receive plasma and/or platelet transfusions. The completion of these studies will facilitate the development of evidence-based recommendations., Competing Interests: Dr. Bembea’s institution received funding from the National Institute of Neurological Disorders and Stroke (R01NS106292), the National Institute of Child Health and Human Development, and Grifols Investigator Sponsored Research Grant.

Background: Malnutrition in critically ill patients is common in neonates and children, including those that receive extracorporeal life support (ECLS). We hypothesize that nutritional adequacy is highly variable, overall nutritional adequacy is poor, and enteral nutrition is underutilized in this population., Materials and Methods: A retrospective study of neonates and children (age<18 y) receiving ECLS at 5 centers from 2012 to 2014 was performed. Demographic, clinical, and outcome data were analyzed. Continuous variables are presented as median [IQR]. Adequate nutrition was defined as meeting 66% of daily caloric goals during ECLS support., Results: Two hundred and eighty three patients received ECLS; the median age was 12 d [3 d, 16.4 y] and 47% were male. ECLS categories were neonatal pulmonary 33.9%, neonatal cardiac 25.1%, pediatric pulmonary 17.7%, and pediatric cardiac 23.3%. The predominant mode was venoarterial (70%). Mortality was 41%. Pre-ECLS enteral and parenteral nutrition was present in 80% and 71.5% of patients, respectively. The median percentage days of adequate caloric and protein nutrition were 50% [0, 78] and 67% [22, 86], respectively. The median percentage days with adequate caloric and protein nutrition by the enteral route alone was 22% [0, 65] and 0 [0, 50], respectively. Gastrointestinal complications occurred in 19.7% of patients including hemorrhage (4.2%), enterocolitis (2.5%), intra-abdominal hypertension or compartment syndrome (0.7%), and perforation (0.4%)., Conclusions: Although nutritional delivery during ECLS is adequate, the use of enteral nutrition is low despite relatively infrequent observed gastrointestinal complications., (Copyright © 2019 Elsevier Inc.

Objectives: To date, there are no published guidelines to direct RBC transfusion decision-making specifically for critically ill children. We present the recommendations from the Pediatric Critical Care Transfusion and Anemia Expertise Initiative., Design: Consensus conference series of multidisciplinary, international experts in RBC transfusion management of critically ill children., Setting: Not applicable., Intervention: None., Subjects: Children with, or children at risk for, critical illness who receive or are at risk for receiving a RBC transfusion., Methods: A panel of 38 content and four methodology experts met over the course of 2 years to develop evidence-based, and when evidence lacking, expert consensus-based recommendations regarding decision-making for RBC transfusion management and research priorities for transfusion in critically ill children. The experts focused on nine specific populations of critically ill children: general, respiratory failure, nonhemorrhagic shock, nonlife-threatening bleeding or hemorrhagic shock, acute brain injury, acquired/congenital heart disease, sickle cell/oncology/transplant, extracorporeal membrane oxygenation/ventricular assist/ renal replacement support, and alternative processing. Data to formulate evidence-based and expert consensus recommendations were selected based on searches of PubMed, EMBASE, and Cochrane Library from 1980 to May 2017. Agreement was obtained using the Research and Development/UCLA Appropriateness Method. Results were summarized using the Grading of Recommendations Assessment, Development, and Evaluation method., Measurements and Results: The Transfusion and Anemia Expertise Initiative consensus conference developed and reached consensus on a total of 102 recommendations (57 clinical [20 evidence based, 37 expert consensus], 45 research recommendations). All final recommendations met agreement, defined a priori as greater than 80%. A decision tree to aid clinicians was created based on the clinical recommendations., Conclusions: The Transfusion and Anemia Expertise Initiative recommendations provide important clinical guidance and applicable tools to avoid unnecessary RBC transfusions. Research recommendations identify areas of focus for future investigation to improve outcomes and safety for RBC transfusion.
