J Clin Anesth 2024; 94:111405. [PMID: 38309132 PMCID: PMC10939750 DOI: 10.1016/j.jclinane.2024.111405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 01/12/2024] [Accepted: 01/29/2024] [Indexed: 02/05/2024]
Abstract
STUDY OBJECTIVE To evaluate the association between pretransfusion and posttransfusion hemoglobin concentrations and the outcomes of children undergoing noncardiac surgery. DESIGN Retrospective review of patient records. We focused on initial postoperative hemoglobin concentrations, which may provide a more useful representation of transfusion adequacy than pretransfusion hemoglobin triggers (the latter often cannot be obtained during acute surgical hemorrhage). SETTING Single-center, observational cohort study. PATIENTS We evaluated all pediatric patients undergoing noncardiac surgery who received intraoperative red blood cell transfusions from January 1, 2008, through December 31, 2018. INTERVENTIONS None. MEASUREMENTS Associations between pre- and posttransfusion hemoglobin concentrations (g/dL), hospital-free days, intensive care unit admission, postoperative mechanical ventilation, and infectious complications were evaluated with multivariable regression modeling. MAIN RESULTS In total, 113,713 unique noncardiac surgical procedures in pediatric patients were evaluated, and 741 procedures met inclusion criteria (median [range] age, 7 [1-14] years). Four hundred ninety-eight patients (68%) with a known preoperative hemoglobin level had anemia; of these, 14% had a preexisting diagnosis of anemia in their health record. Median (IQR) pretransfusion hemoglobin concentration was 8.1 (7.4-9.2) g/dL and median (IQR) initial postoperative hemoglobin concentration was 10.4 (9.3-11.6) g/dL. Each decrease of 1 g/dL in the initial postoperative hemoglobin concentration was associated with increased odds of transfusion within the first 24 postoperative hours (odds ratio [95% CI], 1.62 [1.37-1.93]; P < .001). No significant relationships were observed between postoperative hemoglobin concentrations and hospital-free days (P = .56), intensive care unit admission (P = .71), postoperative mechanical ventilation (P = .63), or infectious complications (P = .74). CONCLUSIONS In transfused patients, there was no association between postoperative hemoglobin values and clinical outcomes, except the need for subsequent transfusion. Most transfused patients presented to the operating room with anemia, which suggests a potential opportunity for perioperative optimization of health before surgery.

[PMID: 38051160 PMCID: PMC10979439 DOI: 10.3238/arztebl.m2023.0243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 11/08/2023] [Accepted: 11/08/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND Approximately 1% to 2% of all hospitalized children receive a transfusion of blood products, in Germany as in other countries. High-quality scientific evidence on transfusions in children is scarce. The available evidence is discussed in this review. METHODS This review is based on publications on blood product transfusions in children that were retrieved by a literature search, including clinical studies, international guideline recommendations, the recommendations of the German cross-sectional guideline, and results of other recent, relevant publications. RESULTS A restrictive transfusion strategy is recommended for all children, including those who are critically ill. Randomized controlled trials have shown that a restrictive strategy for erythrocyte concentrate transfusion in the intensive care unit is safe for children, including neonates. No robust data are available to enable the definition of a suitable threshold for the intraoperative administration of red blood cell concentrates in children undergoing extracardiac surgery. On the basis of studies from pediatric intensive care units, transfusions for hemodynamically stable children with a hemoglobin concentration of more than 7 g/dL are recommended only in exceptional cases. Therapeutic plasma is not recommended as volume replacement, except in massive transfusion. Platelet concentrate transfusions are indicated in case of active hemorrhage, and only rarely for prophylaxis. CONCLUSION There is a broad lack of evidence from randomized controlled trials concerning the indications for transfusions in children. A restrictive transfusion strategy, which has been found safe in the intensive-care setting, is favored by the guidelines in the perioperative setting as well. Further studies are needed to evaluate transfusion triggers and indications for all types of blood products, especially therapeutic plasma. Until more evidence is available, physicians should be aware of what the current evidence supports, and blood products should be given restrictively, and not prophylactically.

In hospitalized patients undergoing therapeutic plasma exchange, major bleeding prevalence depends on the bleeding definition: An analysis of The Recipient Epidemiology and Donor Evaluation Study-III. J Clin Apher 2023; 38:694-702.

Abstract
BACKGROUND Major bleeding in patients undergoing therapeutic plasma exchange (TPE) has been studied in large databases; but without standardizing bleeding definitions. Therefore, we used standardized definitions to evaluate major bleeding in hospitalized patients undergoing TPE using public use data files from the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III). STUDY DESIGN AND METHODS In a retrospective cross-sectional analysis, we identified TPE-treated adults in a first inpatient encounter. We evaluated major bleeding prevalence using (1) International Classification of Diseases (ICD) or Current Procedural Terminology (CPT) codes, (2) packed red blood cell (PRBC) transfusion, or (3) hemoglobin (Hgb) decline. Patients with major bleeding prior to their first TPE were excluded from the analysis. RESULTS Among 779 patients undergoing TPE, major bleeding by at least one of the three bleeding definitions occurred in 135 patients (17.3%). For each of the ICD/CPT, PRBC, and Hgb definitions, the prevalence of major bleeding was 2.8% (n = 31), 7.4% (n = 81), and 5.4% (n = 59), respectively. Only 3.7% of bleeds (5/135) were captured by all three definitions and 19.3% (26/135) exclusively by any two pairwise definitions. The addition of PRBC transfusion and Hgb decline to ICD/CPT code definitions increased bleeding prevalence threefold. CONCLUSION Among hospitalized adults undergoing TPE in the REDS-III study, the prevalence of major bleeding was 17.3%. The addition of PRBC and Hgb decline to ICD codes increased bleeding prevalence threefold. Future studies are needed to develop validated models that identify patients at risk for major bleeding during TPE.

Abstract
BACKGROUND Although pediatric residents frequently order blood products, transfusion medicine (TM) education is both limited and unstandardized during postgraduate training. Using Delphi methodology, this study aimed to identify and prioritize which pediatric TM curricular topics are most important to inform postgraduate training in TM for general pediatricians and pediatric subspecialists. METHODS A national panel of experts iteratively rated potential curricular topics, on a 5-point scale, to determine their priority for inclusion within a TM curriculum. After each round, responses were analyzed. Topics receiving a mean rating <3/5 were removed from subsequent rounds and remaining topics were resent to the panel for further ratings until consensus was achieved, defined as Cronbach α ≥ 0.95. At conclusion of the Delphi process, topics rated ≥4/5 were considered core curricular topics, while topics rated ≥3 to <4 were considered extended topics. RESULTS Forty-five TM experts from 17 Canadian institutions and 12 subspecialties completed the first Delphi round and 31 completed the second. Fifty-seven potential curricular topics were generated from a systematic literature review and Delphi panelists. Two survey rounds were completed before consensus was achieved. Seventy-three topics in six domains reached consensus: 31 core curricular topics and 42 extended topics. There were no significant differences in ratings between TM and non-TM specialists. DISCUSSION A multispecialty Delphi panel reached consensus in identification of curricular topics for pediatric resident physicians. These results set the stage to develop a pediatric TM curriculum that will be foundational for pediatric trainees to enhance learning and improve transfusion safety.

Abstract
Despite the substantial transfusion requirements, there are few studies on the optimal transfusion strategy in pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Our study aimed to retrospectively analyze red blood cell (RBC) and platelet (PLT) transfusion practices during the first 100 days after HSCT at the pediatric hematology/oncology unit of our hospital between 2016 and 2019, due to a more restrictive approach adopted after 2016. We also evaluated the impact on patient outcomes. A total of 146 consecutive HSCT patients were analyzed. In patients without hemorrhagic complications, the Hb threshold for RBC transfusions decreased significantly from 2016 to 2017 (from 7.8 g/dL to 7.3 g/dL; p = 0.010), whereas it remained the same in 2017, 2018, and 2019 (7.3, 7.2, and 7.2 g/dL, respectively). Similarly, the PLT threshold decreased significantly from 2016 to 2017 (from 18,000 to 16,000/μL; p = 0.026) and further decreased in 2019 (15,000/μL). In patients without severe hemorrhagic complications, the number of RBC and PLT transfusions remained very low over time. No increase in 100-day and 180-day non-relapse mortality or adverse events was observed during the study period. No patient died due to hemorrhagic complications. Our preliminary observations support robust studies enrolling HSCT patients in patient blood management programs.

Abstract
PURPOSE OF REVIEW The use of restrictive transfusion triggers to avoid unnecessary transfusions is one important pillar of Patient Blood Management (PBM). For the safe application of this principle in pediatric patients, anesthesiologists need evidence-based guidelines for hemoglobin (Hb) transfusions thresholds in this specially vulnerable age-group. RECENT FINDINGS This review outlines recent prospective and observational studies examining transfusion thresholds in pediatrics. Recommendations to use transfusion triggers in the perioperative or intensive care setting are summarized. SUMMARY Two high-quality studies confirmed that the use of restrictive transfusion triggers in preterm infants in the intensive care unit (ICU) is reasonable and feasible. Unfortunately, no recent prospective study could be found investigating intraoperative transfusion triggers. Some observational studies showed wide variability in Hb levels before transfusion, a tendency toward restrictive transfusion practices in preterm infants, and liberal transfusion practices in older infants. Although there are comprehensive and useful guidelines for clinical practice in pediatric transfusion, most of them do not cover the intraoperative period in particular because of a lack of high-quality studies. This lack of prospective randomized trials focusing on intraoperative transfusion management remains a major problem for the application of pediatric PBM.

Platelet Transfusions in a Multi-NICU Healthcare Organization Before And After Publication of the PlaNeT-2 Clinical Trial. J Pediatr 2023:113388. [PMID: 36933765 DOI: 10.1016/j.jpeds.2023.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 03/06/2023] [Accepted: 03/12/2023] [Indexed: 03/20/2023]
Abstract
OBJECTIVES To evaluate whether implementing more restrictive NICU platelet transfusion guidelines following the PlaNeT-2 randomized controlled trial (transfusion threshold changed from 50,000/μL to 25,000/μL for most neonates) was associated with fewer NICU patients receiving a platelet transfusion, without adversely affecting outcomes. STUDY DESIGN Multi-NICU retrospective analysis of platelet transfusions, patient characteristics, and outcomes during three years before vs. three years after revising system-wide guidelines. RESULTS During the first period, 130 neonates received one or more platelet transfusions; this fell to 106 during the second. The transfusion rate was 15.9/1000 NICU admissions in the first period vs. 12.9 in the second (p=0.106). During the second period, a smaller proportion of transfusions was administered when the platelet count was in the 50,000 - 100,000/μL range (p=0.017), and a larger proportion when it was <25,000/μL (p=0.083). We also saw a fall in the platelet counts that preceded the order for transfusion from 43,100/μL to 38,000/μL (p=0.044). The incidence of adverse outcomes did not change. CONCLUSIONS Changing platelet transfusion guidelines in a multi-NICU network to a more restrictive practice was not associated with a significant reduction in number of neonates receiving a platelet transfusion. The guideline implementation was associated with a reduction in the mean platelet count triggering a transfusion. We speculate that further reductions in platelet transfusions can safely occur with additional education and accountability tracking.

Abstract
ABSTRACT Transfusion of blood products to a hemorrhaging pediatric trauma patient requires seamless partnership and communication between trauma, emergency department, critical care, and transfusion team members. To avoid confusion and delays, understanding of blood banking principles and mutually agreed upon procedures and policies must be regularly updated as knowledge evolves. Because pediatric patients require specialized considerations distinct from those in adults, this brief review covers transfusion principles, policies, and procedures specific to the resuscitation of pediatric trauma patients.

Abstract
Critically ill children commonly receive coagulant products (plasma and/or platelet transfusions) to prevent or treat hemorrhage or correct coagulopathy. Unique aspects of pediatric developmental physiology, and the complex pathophysiology of critical illness must be considered and balanced against known transfusion risks. Transfusion practices vary greatly within and across institutions, and high-quality evidence is needed to support transfusion decision-making. We present recent recommendations and expert consensus statements to direct clinicians in the decision to transfuse or not to transfuse hemostatic blood products, including plasma, platelets, cryoprecipitate, and recombinant products to critically ill children.

Abstract
BACKGROUND Each year the AABB Clinical Transfusion Medicine Committee (CTMC) procures a synopsis highlighting new, important, and clinically relevant studies in the field of transfusion medicine (TM). This has been made available as a publication in Transfusion since 2018. METHODS CTMC members reviewed and identified original manuscripts covering TM-related topics published electronically (ahead-of-print) or in print from December 2020 to December 2021. Selection of publications was discussed at committee meetings and chosen based on perceived relevance and originality. Next, committee members worked in pairs to create a synopsis of each topic, which was then reviewed by additional committee members. The first and senior authors assembled the final manuscript. Although this synopsis is extensive, it is not exhaustive, and some articles may have been excluded or missed. RESULTS The following topics are included: blood products; convalescent plasma; donor collections and testing; hemoglobinopathies; immunohematology and genomics; hemostasis; patient blood management; pediatrics; therapeutic apheresis; and cell therapy. CONCLUSIONS This synopsis highlights and summarizes recent key developments in TM and may be useful for educational purposes.

Abstract
PURPOSE OF REVIEW We sought to describe the current use of platelet transfusions, harms associated with platelet transfusion, new methods of platelet processing that attempt to address these harms, and recent platelet transfusion guidance specific to critically ill children. RECENT FINDINGS Platelet transfusions have been associated with significant morbidity and mortality. New processing techniques, such as pathogen reduction, have been developed to combat infectious risks but in a recent trial of platelet transfusion thresholds in neonates, transfusing platelets more liberally was associated with increased bleeding and mortality. SUMMARY Recent efforts to develop evidence-based guidelines for platelet transfusion in critically ill children were limited by the lack of evidence. However, given the significant risks, restrictive transfusion thresholds should be considered.

The Recipient Epidemiology and Donor Evaluation Study-IV-Pediatric (REDS-IV-P): A research program striving to improve blood donor safety and optimize transfusion outcomes across the lifespan. Transfusion 2022; 62:982-999. [PMID: 35441384 PMCID: PMC9353062 DOI: 10.1111/trf.16869] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 03/04/2022] [Accepted: 03/04/2022] [Indexed: 12/19/2022]
Abstract
BACKGROUND The Recipient Epidemiology and Donor Evaluation Study-IV-Pediatric (REDS-IV-P) is a new iteration of prior National Heart, Lung, and Blood Institute (NHLBI) REDS programs that focus on improving transfusion recipient outcomes across the lifespan as well as the safety and availability of the blood supply. STUDY DESIGN AND METHODS The US program includes blood centers and hospitals (22 including 6 free-standing Children's hospitals) in four geographic regions. The Brazilian program has 5 participating hemocenters. A Center for Transfusion Laboratory Studies (CTLS) and a Data Coordinating Center (DCC) support synergistic studies and activities over the 7-year REDS-IV-P program. RESULTS The US is building a centralized, vein-to-vein (V2V) database, linking information collected from blood donors, their donations, the resulting manufactured components, and data extracts from hospital electronic medical records of transfused and non-transfused patients. Simultaneously, the Brazilian program is building a donor, donation, and component database. The databases will serve as the backbone for retrospective and prospective observational studies in transfusion epidemiology, transfusion recipient outcomes, blood component quality, and emerging blood safety issues. Special focus will be on preterm infants, patients with sickle cell disease, thalassemia or cancer, and the effect of donor biologic variability and component manufacturing on recipient outcomes. A rapid response capability to emerging safety threats has resulted in timely studies related to Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2). CONCLUSIONS The REDS-IV-P program endeavors to improve donor-recipient-linked research with a focus on children and special populations while also maintaining the flexibility to address emerging blood safety issues.

Arora S, Dua S, Goel R. Neonatal and pediatric transfusion practices and policies in India: A survey-based cross-sectional assessment of blood centers. Transfusion 2022; 62:1000-1009. [PMID: 35357016 DOI: 10.1111/trf.16857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 03/01/2022] [Accepted: 03/03/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Blood centers play a critical role in supporting neonatal and pediatric transfusions. We aim to study the variation in pediatric/neonatal transfusion policies and practices for blood centers in India. STUDY DESIGN AND METHODS This is a survey-based (45 question) cross-sectional assessment of blood centers in India supporting pediatric/neonatal transfusions. RESULTS One hundred three centers responded to the survey (response rate 51.2%; 103/201). As a part of pretransfusion testing, use of "microtainers" was reported by 58.4% (59/101) centers and only 57.4% (58/101) centers provide antibody screening. In case of absence of maternal sample, type O negative blood is most commonly used (48.5%; 49/101), and in case of ABO incompatibility, 68.3% (69/101) use units compatible with both mother and newborn. Leukoreduced RBCs are provided by 89% (90/101) centers and irradiated products are provided by 48.5% (49/101). 82% (83/101) of centers reported not receiving requests for CMV negative units considering the high incidence of CMV-seropositivity in donors. Fresh units are defined as <7 days old by 44.5% (45/101) and <5 days old by 31.6% (32/101) centers. 97% centers reported SAGM suspended RBCs in inventory but only 67.3% (68/101) use them for top-up transfusions to neonates. Overall >80% centers use the buffy-coat method for platelet concentrates preparation. Volume-based (ml/kg) aliquots preparation is done by 88% (89/101), mainly using the sterile connecting device (84.6%; 83/98). CONCLUSION This survey shows heterogeneity and lack of standardization in practices across blood centers in India and highlights the need for more studies to establish best practices for this vulnerable age group.

Hsien S, Dayton JD, Chen D, Stock A, Bacha E, Cushing MM, Nellis ME. Hemostatic efficacy of pathogen-reduced platelets in children undergoing cardiopulmonary bypass. Transfusion 2022; 62:298-305. [PMID: 34904250 PMCID: PMC8837684 DOI: 10.1111/trf.16768] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 11/10/2021] [Accepted: 11/15/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Pediatric patients undergoing cardiopulmonary bypass (CPB) often require blood component transfusions. Pathogen-reduction (PR) of platelets reduces the risk of microbial contamination; however, its effect on hemostatic efficacy in this population is unclear. This study sought to characterize the hemostatic efficacy of PR platelets in children undergoing CPB. STUDY DESIGN AND METHODS We performed a retrospective chart review of patients admitted to a pediatric intensive care unit following CPB surgery from 2015 to 2019. Demographic data, validated scoring of repair complexity, products received, and outcomes were compared. The primary outcome was postoperative chest tube bleeding. RESULTS A total of 140 patients were enrolled. The majority of surgeries (124/140) were Risk Adjustment for Congenital Heart Surgery (RACHS) 1-3 repairs. Seventy-four percent of patients (104/140) received only standard platelets whereas 26% (36/140) received PR platelets. There were no differences between the groups in the age (p = .90), sex (p = .20) or RACHS score (p = .06). Postoperatively, there was no difference in the median chest tube output for 1 h (p = .27), 2 h (p = .26), 4 h (p = .09), 8 h (p = .16), or for the first 24 h following surgery (p = .23) in patients who received standard versus PR platelets. There was also no difference in receipt of platelets (p = .18), cell saver (p = .79), or cryoprecipitate (p = .28). CONCLUSION Patients receiving PR platelets did not have more blood loss or require more transfusions than those who received standard platelets. This suggests that PR platelets may provide acceptable hemostasis with the additional benefits of reduced risk of microbial contamination in pediatric patients undergoing CPB.

Abstract
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.
