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
Patient blood management (PBM) strategies are needed in the neonate and paediatric population, given that haemoglobin thresholds used are often higher than recommended by evidence, with exposure of children to potential complications without meaningful benefit. A literature review was performed on the following topics: evidence-based transfusions of blood components and pharmaceutical agents. Other topics reviewed included perioperative coagulation assessment and perioperative PBM. The Transfusion and Anaemia Expertise Initiative (TAXI) consortium published a consensus statement addressing haemoglobin (Hb) transfusion threshold in multiple subsets of patients. A multicentre trial (PlaNeT-2) reported a higher risk of bleeding and death or serious new bleeding among infants who received platelet transfusion at a higher (50 000/μl) compared to a lower (25 000/μl) threshold. Recent data support the use of a restrictive transfusion threshold of 25 000/μl for prophylactic platelet transfusions in preterm neonates. The TAXI-CAB consortium mentioned that in critically ill paediatric patients undergoing invasive procedures outside of the operating room, platelet transfusion might be considered when the platelet count is less than or equal to 20 000/μl and there is no benefit of platelet transfusion when the platelet count is more than 50 000/μl. There are limited controlled studies in paediatric and neonatal population regarding plasma transfusion. Blood conservation strategies to minimise allogenic blood exposure are essential to positive patient outcomes neonatal and paediatric transfusion practices have changed significantly in recent years since randomised controlled trials were published to guide practice. Additional studies are needed in order to provide practice change recommendations.

Abstract
OBJECTIVE Guidelines adherence in emergency departments (EDs) relies partly on the availability of resources to improve sepsis care and outcomes. Our objective was to assess the management of pediatric septic shock (PSS) in Latin America's EDs and to determine the impact of treatment coordinated by a pediatric emergency specialist (PEMS) versus nonpediatric emergency specialists (NPEMS) on guidelines adherence. METHODS Prospective, descriptive, and multicenter study using an electronic survey administered to PEMS and NPEMS who treat PSS in EDs in 14 Latin American countries. RESULTS We distributed 2164 surveys with a response rate of 41.5%, of which 22.5% were PEMS. Overall American College of Critical Care Medicine reported guidelines adherence was as follows: vascular access obtained in 5 minutes, 76%; fluid infusion technique, 60%; administering 40 to 60 mL/kg within 30 minutes, 32%; inotropic infusion by peripheral route, 61%; dopamine or epinephrine in cold shock, 80%; norepinephrine in warm shock, 57%; and antibiotics within 60 minutes, 82%. Between PEMS and NPEMS, the following differences were found: vascular access in 5 minutes, 87.1% versus 72.7% (P < 0.01); fluid infusion technique, 72.3% versus 55.9% (P < 0.01); administering 40 to 60 mL/kg within 30 minutes, 42% versus 29% (P < 0.01); inotropic infusion by peripheral route, 75.7% versus 56.3% (P < 0.01); dopamine or epinephrine in cold shock, 87.1% versus 77.3% (P < 0.05); norepinephrine in warm shock, 67.8% versus 54% (P < 0.01); and antibiotic administration within first 60 minutes, 90.1% versus 79.3% (P < 0.01), respectively. Good adherence criteria were followed by 24%. The main referred barrier for sepsis care was a failure in its recognition, including the lack of triage tools. CONCLUSIONS In some Latin American countries, there is variability in self-reported adherence to the evidence-based recommendations for the treatment of PSS during the first hour. The coordination by PEMS support greater adherence to these recommendations.

Abstract
BACKGROUND Pediatric patients with sepsis in intensive care units are at high risk of developing anemia, which might have adverse effects on their prognosis. This study aimed to evaluate the impact of red blood cell (RBC) transfusion on the outcomes of patients admitted to a pediatric intensive care unit (PICU) with sepsis. METHODS We conducted a prospective randomized clinical trial, enrolling 67 children, aged 2 to 144 months who were admitted to a PICU with a new episode of sepsis from November 2017 to April 2018. Patients were allocated randomly to two groups: Group 1, liberal transfusion strategy group, including 33 patients who had initial hemoglobin (Hb) between 7 or greater and less than 10 g/dL and received an RBC top-up transfusion to 12 g/dL; and Group 2, restrictive strategy group, including 34 patients who had the same Hb range and did not receive RBCs. Patients with Hb less than 7 or greater than 10 g/dL were excluded. RESULTS Of 33 patients who received liberal transfusions, 31 (93.94%) required ventilation, and 29 (87.88%) had multiorgan dysfunction. They had a significantly lengthier hospital stay and a higher incidence of acute respiratory distress syndrome and acute lung injury. Moreover, mortality was significantly higher in the liberal transfusion group (42.4% vs. 17.6%). CONCLUSIONS Compared to the restrictive transfusion strategy, liberal transfusion might be associated with a worse outcome. However, the possible role of other known and unknown confounding factors and minor protocol violations should be taken into consideration. We recommend minimizing factors worsening anemia in PICU patients to reduce the need for transfusion.

Abstract
BACKGROUND Though weight is a major consideration when transfusing blood in pediatric patients, it is generally not considered when dosing transfusions in adults. We hypothesized that the change in hemoglobin (Hb) concentration is inversely proportional to body weight when transfusing red blood cells (RBC) in adults. METHODS A total of 13,620 adult surgical patients at our institution were assessed in this retrospective cohort study (2009-2016). Patients were stratified based on total body weight (kg): 40-59.9 (16.6%), 60-79.9 (40.4%), 80-99.9 (28.8%), 100-119.9 (11.3%), and 120-139.9 (2.9%). The primary outcome was the change in Hb per RBC unit transfused. Subgroup analyses were performed after stratification by sex (male/female) and the total number of RBC units received (1/2/≥3 units). Multivariable models were used to assess the association between weight and change in Hb. RESULTS As patients' body weight increased, there was a decrease in the mean change in Hb per RBC unit transfused (40-59.9 kg: 0.85 g/dL, 60-79.9 kg: 0.73 g/dL, 80-99.9 kg: 0.66 g/dL, 100-119.9 kg: 0.60 g/dL, 120-139.9 kg: 0.55 g/dL; p < .0001). This corresponded with a 35% difference in the change in Hb between the lowest and highest weight categories on univariate analysis. Similar trends were seen after subgroup stratification. On multivariable analysis, for every 20 kg increase in patient weight, there was a ~6.5% decrease in the change in Hb per RBC unit transfused (p < .0001). CONCLUSIONS Patient body weight differentially impacts the change in Hb after RBC transfusion. These findings justify incorporating body weight into the clinical decision-making process when transfusing blood in adult surgical patients.

Abstract
Purpose: Risks of red blood cell transfusion may outweigh benefits for many patients in Pediatric Intensive Care Units (PICUs). The Transfusion and Anemia eXpertise Initiative (TAXI) recommendations seek to limit unnecessary and potentially harmful transfusions, but use has been variable. We sought to identify barriers and facilitators to using the TAXI recommendations to inform implementation efforts. Materials and Methods: The integrated Promoting Action on Research Implementation in Health Services (iPARIHS) framework guided semi-structured interviews conducted in 8 U.S. ICUs; 50 providers in multiple ICU roles completed interviews. Adapted Framework analysis, a form of content analysis, used the iPARIHS innovation, recipient, context and facilitation constructs and subconstructs to categorize data and identify patterns as well as unique informative statements. Results: Providers perceived that the TAXI recommendations would reduce transfusion rates and practice variability, but adoption faced challenges posed by attitudes around transfusion and care in busy and complex units. Development of widespread buy-in and inclusion in implementation, integration into workflow, designating committed champions, and monitoring outcomes data were expected to enhance implementation. Conclusions: Targeted activities to create buy-in, educate, and plan for use are necessary for TAXI implementation. Recognition of contextual challenges posed by the PICU environment and an approach that adjusts for barriers may optimize adoption.

Blood Management and Risk Assessment for Transfusion in Pediatric Spinal Deformity Surgery. Adv Hematol 2020; 2020:8246309.

Abstract
Objectives Evaluate the impact of a Quality and Safety Program (QSP) on the reduction of blood loss and transfusion needs in pediatric spinal deformity surgery, while defining risk factors for transfusion. Background Multimodal plan aiming to minimize transfusion needs has been shown to reduce transfusions and index rates in spinal deformity surgery. Anticipating blood loss and transfusion may help direct resources to patient needs or encourage reconsideration of the surgical plan. Methods This is a single-center retrospective study of prospectively collected data. Impact of this multimodal plan was studied on idiopathic deformities (Group A, 109 patients) and scoliosis associated with syndromic, neuromuscular, and muscular dystrophies (Group B, 100 patients), both before and after QSP. Results A decrease in total estimated blood loss was observed. In Group A, transfused patients decreased from 83.7% to 28% (p < 0.001, odds: 0.077), and, in Group B, from 98.7% to 66% (p < 0.01, odds: 0.038). Pearson's correlation identified patient body weight (r = 0.245, p=0.001) and Cobb angle (r = 0.175, p=0.017) as factors related to blood loss. A linear regression model to estimate hematic losses revealed that only body weight and transfusion showed predictive power, resulting in a low predictive model (R2 = 0.156; F(3,167) = 15.483, p < 0.001). A mediated model to explain blood loss was built based on a set of variables influencing transfusion which is, in turn, related to blood loss. Conclusion Transfusion needs in scoliosis surgery can be substantially reduced following a multimodal approach. The success of a program is strongly dependent on team effort, and the introduction of a risk assessment tool for transfusion needs indirectly assesses surgical risk, thus allowing relocation of resources to decrease blood loss.

Abstract
Transfusion is a frequent treatment in pediatric patients with acute respiratory distress syndrome (PARDS) although evidence to support transfusion decision-making is lacking. The purpose of this review is to review the current state of knowledge on the issue of transfusion in children with PARDS and to detail the possible beneficial effects and potential deleterious impacts of transfusion in this patient population. Based on the current literature and recent guidelines, a restrictive red blood cell (RBC) transfusion strategy (avoidance of transfusion when the haemoglobin level is above 7 g/dL) is indicated in stable patients without severe PARDS, as these were excluded from the large trials. In children with severe PARDS, further research is needed to determine if factors other than the haemoglobin level might guide RBC transfusion decision-making by better characterizing the presence of low oxygen delivery (DO2). Additionally, appropriate indications for prophylactic transfusion of hemostatic products (plasma or platelets) in children with PARDS are lacking.

Abstract
BACKGROUND Blood transfusion is costly and associated with various medical risks. Studies in critically ill adult and pediatric patients suggest that implementation of more restrictive transfusion protocols based on lower threshold hemoglobin concentrations can be medically and economically advantageous. The purpose of this study was to evaluate the implications of a hemoglobin threshold change in pediatric burn patients. METHODS We implemented a change in hemoglobin threshold from 10 g/dL to 7 g/dL and compared data from patients before and after this protocol change in a retrospective review. Primary endpoints were hemoglobin concentration at baseline, before transfusion, and after transfusion; amount of blood product administered; and mortality. Secondary endpoints were the incidence of sepsis based on the American Burn Association physiological criteria for sepsis and mean number of septic days per patient. All endpoint analyses were adjusted for relevant clinical covariates via generalized additive models or Cox proportional hazard model. Statistical significance was accepted at p less than 0.05. RESULTS Patient characteristics and baseline hemoglobin concentrations (pre, 13.5 g/dL; post, 13.3 g/dL; p > 0.05) were comparable between groups. The group transfused based on the more restrictive hemoglobin threshold had lower hemoglobin concentrations before and after transfusion throughout acute hospitalization, received lower volumes of blood during operations (pre, 1012 mL; post, 824 mL; p < 0.001) and on days without surgical procedures (pre, 602 mL; post, 353 mL; p < 0.001), and had a lower mortality (pre, 8.0%; post, 3.9%; mortality hazard decline, 0.55 [45%]; p < 0.05). Both groups had a comparable incidence of physiological sepsis, though the more restrictive threshold group had a lower number of sepsis days per patient. CONCLUSION More restrictive transfusion protocols are safe and efficacious in pediatric burn patients. The associated reduction of transfused blood may lessen medical risks of blood transfusion and lower economic burden. LEVEL OF EVIDENCE Therapeutic, level IV.

Standardized Implementation of Evidence-based Guidelines to Decrease Blood Transfusions in Pediatric Intensive Care Units. Pediatr Qual Saf 2019; 4:e165.

Abstract
Introduction Despite evidence that red blood cell (RBC) transfusions may be associated with more harm than benefit, current transfusion practices vary significantly. This multicenter, quality improvement study aimed to sustainably decrease the rate of RBC transfusions in pediatric intensive care units (PICUs). Methods This 16-month prospective study included 5 PICUs. We implemented a standardized project plan including education, bedside tools, real-time reminders, and email feedback. We collected data from consecutive transfusions during pre-implementation (Phase I), postimplementation (Phase II), and post-stabilization phases (Phase III). Results Of the 2,064 RBC transfusions, we excluded 35% (N = 729) from analysis in patients undergoing extracorporeal membrane oxygenation. Transfusion/1,000 admissions improved throughout the study periods from a baseline 209.6 -199.8 in Phase II and 195.8 in Phase III (P value < 0.05). There were fewer transfusions outside of the hemoglobin threshold guideline, decreasing from 81% of transfusions outside of guidelines in Phase I to 74% in Phases II and III, P < 0.05. Study phase, site, co-management status, service of requesting provider, admit reason, previous transfusion status, and age were associated with transfusion above guideline threshold. Conclusions Multicenter collaboration can successfully deploy a standardized plan that adheres to implementation science principles to sustainably decrease the rate of RBC transfusion outside of guideline thresholds. However, we did not decrease the total number of transfusions in our study. The complexity of multiple specialties co-managing patients is common in the contemporary PICU. Educational initiatives aimed at one specialty may have limited effectiveness in a multifaceted system of care.

Abstract
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.

Abstract
OBJECTIVES To present the consensus recommendations and supporting literature for RBC transfusions in general critically ill children from the Pediatric Critical Care Transfusion and Anemia Expertise Initiative. DESIGN Consensus conference series of international, multidisciplinary experts in RBC transfusion management of critically ill children. METHODS The panel of 38 experts developed evidence-based and, when evidence was lacking, expert-based recommendations and research priorities regarding RBC transfusions in critically ill children. The subgroup on RBC transfusion in general critically ill children included six experts. Electronic searches were conducted using PubMed, EMBASE, and Cochrane Library databases from 1980 to May 30, 2017, using a combination of keywords to define concepts of RBC transfusion and critically ill children. Recommendation consensus was obtained using the Research and Development/UCLA Appropriateness Method. The results were summarized using the Grading of Recommendations Assessment, Development, and Evaluation method. RESULTS Three adjudicators reviewed 4,399 abstracts; 71 papers were read, and 17 were retained. Three papers were added manually. The general Transfusion and Anemia Expertise Initiative subgroup developed, and all Transfusion and Anemia Expertise Initiative members voted on two good practice statements, six recommendations, and 11 research questions; in all instances, agreement was reached (> 80%). The good practice statements suggest a framework for RBC transfusion in PICU patients. The good practice statements and recommendations focus on hemoglobin as a threshold and/or target. The research questions focus on hemoglobin and physiologic thresholds for RBC transfusion, alternatives, and risk/benefit ratio of transfusion. CONCLUSIONS Transfusion and Anemia Expertise Initiative developed pediatric-specific good practice statements and recommendations regarding RBC transfusion management in the general PICU population, as well as recommendations to guide future research priorities. Clinical recommendations emphasized relevant hemoglobin thresholds, and research recommendations emphasized a need for further understanding of physiologic thresholds, alternatives to RBC transfusion, and hemoglobin thresholds in populations with limited pediatric literature.

Abstract
OBJECTIVES To present the recommendations and supporting literature for RBC transfusions in critically ill children with bleeding developed by the Pediatric Critical Care Transfusion and Anemia Expertise Initiative. DESIGN Consensus conference series of international, multidisciplinary experts in RBC transfusion management of critically ill children. METHODS The panel of 38 experts developed evidence-based and, when evidence was lacking, expert-based clinical recommendations as well as research priorities for RBC transfusions in critically ill children. The respiratory subgroup included six experts. Electronic searches were conducted using PubMed, EMBASE, and Cochrane Library databases 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. RESULTS Transfusion and Anemia Expertise Initiative experts developed seven recommendations focused on children with acute respiratory failure. All recommendations reached agreement (> 80%). Transfusion of RBCs in children with respiratory failure with an hemoglobin level less than 5 g/dL was strongly recommended. It was strongly recommended that RBCs not be systematically administered to children with respiratory failure who are hemodynamically stable and who have a hemoglobin level greater than or equal to 7 g/dL. Experts could not make a recommendation for children with hemodynamic instability, with severe hypoxemia and/or with an hemoglobin level between 5 and 7 g/dL. Specific RBC transfusion strategies using physiologic-based metrics and biomarkers could not be elaborated. CONCLUSIONS The Transfusion and Anemia Expertise Initiative Consensus Conference developed specific recommendations regarding RBC transfusion management in critically ill children with respiratory failure, as well as recommendations to guide future research. Clinical recommendations emphasize relevant hemoglobin thresholds. Research recommendations emphasize the need to identify appropriate physiologic thresholds, suggest a better understanding of alternatives to RBC transfusion, and identify the need for better evidence on hemoglobin thresholds that might be used in specific subpopulations of critically ill children.

Abstract
BACKGROUND Intestinal failure-associated liver disease (IFALD) can be treated with parenteral fish oil (FO) monotherapy, but practitioners have raised concerns about a potential bleeding risk. This study aims to describe the incidence of clinically significant post-procedural bleeding (CSPPB) in children receiving FO monotherapy. METHODS A retrospective chart review was performed on patients at our institution treated with intravenous FO for IFALD. CSPPB was defined as bleeding leading to re-operation, transfer to the intensive care unit, re-admission, or death, up to one month after any invasive procedure. RESULTS From 244 patients reviewed, 183 underwent ≥1 invasive procedure(s) (n = 732). Five (0.68%, 95% CI 0.22-1.59%) procedures resulted in CSPPB. FO therapy was never interrupted. No deaths due to bleeding occurred. CONCLUSIONS Findings suggest that FO therapy is safe, with a CSPPB risk no greater than that reported in the general population. O3FA should not be held in preparation for procedures or in the event of bleeding.

Abstract
OBJECTIVE To determine whether judicious blood testing impacts timing or amount of packed RBC transfusions in infants after heart surgery. DESIGN A retrospective study comparing before and after initiation of a quality improvement process. SETTING A university-affiliated cardiac ICU at a tertiary care children's hospital. PATIENTS Infants less than 1 year old with Risk Adjustment for Congenital Heart Surgery category 4, 5, 6, or d-transposition of great arteries (Risk Adjustment for Congenital Heart Surgery 3) consecutively treated during 2010 through 2013. INTERVENTION A quality improvement process implemented in 2011 to decrease routine laboratory testing after surgery. MEASUREMENTS AND MAIN RESULTS Fifty-two infants preintervention and 214 postintervention had similar age, weight, proportion of cyanotic lesions, and surgical complexity. Infants with single versus biventricular physiology were compared separately. The number of laboratory tests per patient adjusted for cardiac ICU length of stay (laboratory tests/patient/day) was significantly lower in postintervention populations for single and biventricular groups (9 vs 15 and 10 vs 15, respectively; p < 0.001). The proportion of single ventricle patients transfused post- and preintervention was not statistically different (72% vs 90%; p = 0.130). Transfusion in the biventricular groups was the same over time (65% vs 65%). Time to first transfusion was significantly longer in the postintervention single ventricle group (4 vs 1 d; p < 0.001), and was not statistically different in the biventricular patients (4 vs 7 d; p = 0.058). The median hematocrit level at first transfusion was significantly lower (37% vs 40%; p = 0.004) postintervention in the cyanotic population, but did not differ in the biventricular group (31% vs 31%; p = 0.840). CONCLUSION In infants after heart surgery, blood testing targeted to individual needs significantly decreased the number of blood tests, but did not significantly decrease postoperative blood transfusion.

Abstract
BACKGROUND There are no well-designed prospective studies evaluating transfusion practices in pediatric trauma. We sought to describe red blood cell (RBC) transfusion practices in trauma patients who were admitted to a pediatric intensive care unit (PICU). STUDY DESIGN AND METHODS This study is a post-hoc analysis of a prospective, 6-month observational study in 30 PICUs. We studied a total of 580 patients aged less than 18 years who had been admitted to a PICU for more than 48 hours, including 95 who were trauma patients. RESULTS Trauma patients more frequently received transfusion before PICU admission (p < 0.001), were older (p < 0.0001), and more frequently were mechanically ventilated (p = 0.05). In the PICU, trauma patients received more transfusions (55% vs. 37%; p < 0.001), although admission hemoglobin levels were similar in both groups (p = 0.86). The mean (± standard deviation) pretransfusion hemoglobin level in the PICU was 9.0 ± 2.4 g/dL for trauma patients compared with 8.3 ± 2.4 g/dL for nontrauma patients (p = 0.09). Among the trauma patients, transfusion was associated with younger age, higher Pediatric Logistic Organ Regression scores, mechanical ventilation, bleeding, and transfusion before PICU admission. Multivariate regression demonstrated that receiving an RBC transfusion before admission was strongly associated with receiving a blood transfusion in the PICU (p = 0.008). CONCLUSION Trauma patients are at high risk for receiving an RBC transfusion both before and during their PICU stay, despite a similar transfusion threshold compared with nontrauma patients. Transfusion before PICU admission is a strong determinant, suggesting ongoing bleeding that will require re-transfusion. Further studies are needed to evaluate whether a restrictive transfusion strategy can safely be considered in these patients.

Abstract
The optimal red blood cell transfusion threshold for postoperative pediatric cardiac surgery patients is unknown. This study describes the stated red blood cell transfusion practice of physicians who treat postoperative pediatric cardiac surgery patients in intensive care units. A scenario-based survey was sent to physicians involved in postoperative intensive care of pediatric cardiac surgery patients in all Canadian centers that perform such surgery. Respondents reported their red blood cell transfusion practice in four postoperative scenarios: acyanotic or cyanotic cardiac lesion, in a neonate or an infant. In part A of each scenario, the patient was critically ill, but stabilized; in part B, the patient became unstable. Response rate was 58 % (71 of 123), with 45 respondents indicating direct involvement in postoperative intensive care. There was a wide variability in stated transfusion threshold, ranging from <7.0-14.0 g/dL for stabilized cases. There was no significant difference between neonates and infants in stated transfusion threshold. The mean hemoglobin level below which respondents would transfuse a stabilized patient was 9 g/dL for acyanotic and 11.2 g/dL for cyanotic patients, a statistically significant difference (2.2 ± 0.9 g/dL, p < 0.001). All clinical determinants of instability significantly increased transfusion threshold. Hemodynamic instability increased transfusion threshold by 2.3 ± 1.3 g/dL in acyanotic patients and by 1.3 ± 1.1 g/dL in cyanotic patients. Cyanotic lesion and clinical instability, but not patient age, increased stated red blood cell transfusion threshold. Significant variation in reported red blood cell transfusion practice exists among physicians treating pediatric patients in intensive care following cardiac surgery.

Abstract
Since the beginning of the 20th century, blood products have been used to effectively treat life-threatening conditions. Over time, we have come to appreciate the many benefits along with significant risks inherent to blood product transfusions. As such, recommendations for the safe and effective use of blood products have evolved over time. Current evidence supports the use of restrictive transfusion strategies that can avoid the risks of unnecessary transfusions. In spite of good evidence, there is a considerable amount of variability in transfusion practices across providers. Clinical decision support (CDS) is an effective tool capable of increasing adherence to evidence-based practices. CDS has been used successfully to improve adherence to transfusion guidelines. Pediatric literature demonstrates strong evidence for the use of CDS to improve appropriateness of red blood cell and plasma transfusion utilization. Further studies in more diverse settings with more standardized reporting are needed to provide more clarity around the effectiveness of CDS in blood product prescriptions.

Abstract
Red blood cell transfusions are a common life-saving intervention for neonates and children with anemia, but transfusion decisions, indications, and doses in neonates and children are different from those of adults. Patient blood management (PBM) programs are designed to assist clinicians with appropriately transfusing patients. Although PBM programs are well recognized and appreciated in the adult setting, they are quite far from standard of care in the pediatric patient population. Adult PBM standards cannot be uniformly applied to children, and there currently is significant variation in transfusion practices. Because transfusing unnecessarily can expose children to increased risk without benefit, it is important to design PBM programs to standardize transfusion decisions. This article assesses the key elements necessary for a successful pediatric PBM program, systematically explores various possible pediatric specific blood conservation strategies and the current available literature supporting them, and outlines the gaps in the evidence suggesting need for further/improved research. Pediatric PBM programs are critically important initiatives that not only involve a cooperative effort between pediatric surgery, anesthesia, perfusion, critical care, and transfusion medicine services but also need operational support from administration, clinical leadership, finance, and the hospital information technology personnel. These programs also expand the scope for high-quality collaborative research. A key component of pediatric PBM programs is monitoring pediatric blood utilization and assessing adherence to transfusion guidelines. Data suggest that restrictive transfusion strategies should be used for neonates and children similar to adults, but further research is needed to assess the best oxygenation requirements, hemoglobin threshold, and transfusion strategy for patients with active bleeding, hemodynamic instability, unstable cardiac disease, and cyanotic cardiac disease. Perioperative blood management strategies include minimizing blood draws, restricting transfusions, intraoperative cell salvage, acute normovolemic hemodilution, antifibrinolytic agents, and using point-of-care tests to guide transfusion decisions. However, further research is needed for the use of intravenous iron, erythropoiesis-stimulating agents, and possible use of whole blood and pathogen inactivation. There are numerous areas where newly formed collaborations could be used to investigate pediatric transfusion, and these studies would provide critical data to support vital pediatric PBM programs to optimize neonatal and pediatric care.

RESULTS We analyzed the charts of all children between 1 month and 21 years of age who received packed red blood cell (PRBC) transfusions during a 2-year period. The target patients were identified from our blood bank database. For analysis, the patients were subdivided into four groups: acute blood loss (postsurgically, trauma, or acute gastrointestinal bleeding from other causes), hematologic (hematologic malignancies, bone marrow suppression, hemolytic anemia, or sickle cell disease), unstable (FiO2 > 0.6 and/or on inotropic support), and stable groups. We also compared the pre-transfusion hemoglobin threshold in all unstable patients with that of all stable patients. A total of 571 transfusion episodes in 284 patients were analyzed. 28% (n = 160) of transfusions were administered to patients in the acute blood loss group, 36% (n = 206) to hematologic patients, 17% (n = 99) to unstable patients, and 18% (n = 106) to stable patients. The mean pre-transfusion hemoglobin (± SD) in all children as well as in the acute blood loss, hematologic, unstable and stable groups was 7.3 ± 1.20, 7.83 ± 1.32, 6.97 ± 1.31, 7.96 ± 1.37, 7.31 ± 1.09 g/dl, respectively. The transfusion threshold for acute blood loss and unstable groups was higher compared to hematologic and stable groups (p < 0.001; ANOVA with multiple comparisons). The mean pre-transfusion hemoglobin threshold for stable and unstable patients among all groups was 7.3 ± 1.3 and 7.9 ± 1.3 (p < 0.0001), respectively. The observed mortality rate was higher among children who received transfusion compared to other children admitted to PICU. CONCLUSION The hemoglobin threshold for transfusion varied according to clinical conditions. Overall, the hemoglobin threshold for transfusion was 7.3 ± 1.20 g/dl.

Abstract
BACKGROUND Blood has been imbued with powerful connotations through history and across cultures. Currently bestowed with scientific meaning, blood nevertheless carries symbolic resonance. This study examines these representations among practitioners and sheds light on the clinical and nonclinical factors that guide blood transfusion (BT) decision-making in Quebec, Canada. STUDY DESIGN AND METHODS With a qualitative exploratory study design, data were collected in the pediatric intensive care unit and the hematology-oncology unit of Sainte-Justine Hospital in 2009. A total of fifteen 1-hour-long semistructured interviews were conducted with physicians. RESULTS Physicians affirm that the symbolic connotations of blood found in the lay population do not influence their transfusion decisions. However, there are other "social" and "cultural' aspects that influence these practices. Also, BT strategies remain diverse across units. Practitioners perceive these situations as resulting from insufficient training and by the existence of an "oral tradition" and a professional culture that are resistant to change. CONCLUSION BT practices differ within and across units. Many dimensions intervene in the decision to transfuse, from individual clinical appreciation and local unit "culture" to formal and ad hoc training. Consistent change in BT can only occur with the implementation of norms and guidelines that are endorsed by key influential figures. An extensive multicentered study is necessary to better understand how social and cultural factors affect BT practices. This knowledge will sustain an enlightened clinical practice and lead to the recognition that peer practices are also embedded in professional cultures.

Abstract
Essential therapeutic principles in children with septic shock persist over time, although some new concepts have been recently incorporated, and fully awareness of pediatricians and intensivists is essential. Fluid resuscitation is a fundamental intervention, but the kind of ideal fluid has not been established yet, as each of these interventions has specific limitations and there is no evidence supportive of the superiority of one type of fluid. Should septic shock persists despite adequate fluid resuscitation, the use of inotropic medication and/or vasopressors is indicated. New vasoactive drugs can be used in refractory septic shock caused by vasopressors, and the use of hydrocortisone should be considered in children with suspected adrenal insufficiency, as it reduces the need for vasopressors. The indications for red blood cells transfusion or the optimal level of glycemia are still controversial, with no consensus on the threshold value for the use of these blood products or the initiation of insulin administration, respectively. Likewise, the use of high-volume hemofiltration is a controversial issue and further study is needed on the routine recommendation in the course of septic shock. Nutritional support is crucial, as malnutrition is a serious complication that should be properly prevented and treated. The aim of this paper is to provide update on the most recent advances as concerns the treatment of septic shock in the pediatric population.

Abstract
OBJECTIVE To identify the potential complications associated with RBC transfusions. DESIGN Prospective observational study. SETTING PICU in a tertiary children's hospital. PATIENTS All children consecutively admitted to our PICU during a 1-year period. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Data were abstracted from medical charts prospectively. Outcomes possibly attributable to RBC transfusions were looked for daily. In transfused cases, it was considered that an outcome was associated with a transfusion only if it was observed after the first RBC transfusion. During the 1-year study period, 913 consecutive admissions were documented, 842 of which were included. Among them, 144 (17%) were transfused at least once. When comparing transfused cases with nontransfused cases, the odds ratio for new or progressive multiple organ dysfunction syndrome was 5.14 (95% CI, 3.28-8.06; p < 0.001). This association remained statistically significant in the multivariable analysis (odds ratio, 3.85; 95% CI, 2.38-6.24; p < 0.001). Transfused cases were ventilated longer than nontransfused cases (14.1 ± 32.6 vs 4.3 ± 9.6 d, p < 0.001), even after adjustment in a Cox model. The PICU length of stay was significantly increased for transfused cases (12.4 ± 26.2 vs 4.9 ± 10.2 d, p < 0.001), even after controlling for potential confounders. The paired analysis for comparison of pretransfusion and posttransfusion values showed that the arterial partial pressure in oxygen was significantly reduced within the 6 hours after the first RBC transfusion (mean difference, 25.6 torr, 95% CI, 5.7-45.4; p = 0.029). The paired analysis also showed an increased proportion of renal replacement therapy. CONCLUSIONS RBC transfusions in critically ill children were associated with prolonged mechanical ventilation and prolonged PICU stay. The risk of new or progressive multiple organ dysfunction syndrome was also increased in some transfused children. Furthermore, our study questions the ability of stored RBCs to improve oxygenation in critically ill children. Practitioners should take into account these data when prescribing an RBC transfusion to PICU patients.

Abstract
PURPOSE OF REVIEW To discuss the tradeoff between permissive anemia and administering red blood cell transfusion to children in pediatric ICUs. RECENT FINDINGS Postsurgical mortality in adults increases abruptly if their nadir hemoglobin level falls below 5 g/dl. Patients with sepsis, even those in septic shock, and patients with upper gastrointestinal bleeding do not require red blood cell (RBC) transfusion if their hemoglobin level is above 7 g/dl. SUMMARY Anemia is common in critically ill children and is well tolerated most of the time. RBC transfusion is required in cases of hemorrhagic shock and in children with a hemoglobin level below 5 g/dl. Children with sepsis, including septic shock, those with a severe upper gastrointestinal bleeding and all stable critically ill children, including noncyanotic cardiac children older than 28 days, do not require an RBC transfusion if their hemoglobin level is above 7 g/dl. Transfusion threshold in children with univentricular physiology and in critically ill children with a hemoglobin level between 5 and 7 g/dl remains to be determined.

Abstract
Anemia and red blood cell (RBC) transfusion occur frequently in hospitalized patients with cardiac disease. In this narrative review, we report the epidemiology of anemia and RBC transfusion in hospitalized adults and children (excluding premature neonates) with cardiac disease, and on the outcome of anemic and transfused cardiac patients. Both anemia and RBC transfusion are common in cardiac patients, and both are associated with mortality. RBC transfusion is the only way to rapidly treat severe anemia, but is not completely safe. In addition to hemoglobin (Hb) concentration, the determinant(s) that should drive a practitioner to prescribe a RBC transfusion to cardiac patients are currently unclear. In stable acyanotic cardiac patients, Hb level above 70 g/L in children and above 70 to 80 g/L in adults appears safe. In cyanotic children, Hb level above 90 g/L appears safe. The appropriate threshold Hb level for unstable cardiac patients and for children younger than 28 days is unknown. The optimal transfusion strategy in cardiac patients is not well characterized. The threshold at which the risk of anemia outweighs the risk of transfusion is not known. More studies are needed to determine when RBC transfusion is indicated in hospitalized patients with cardiac disease.

Abstract
OBJECTIVES To analyze the RBC transfusion practice patterns among pediatric intensivists in light of the new evidence advocating for a restrictive transfusion strategy. DESIGN Self-administered questionnaire. SETTING PICUs. SUBJECTS Intensivists and fellows in pediatric critical care medicine. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Scenario-based survey carried out among North American and European intensivists, working in tertiary-care PICUs. Respondents were asked to report their decisions with regard to RBC transfusion in stable critically ill children with bronchiolitis, septic shock, trauma, or tetralogy of Fallot repair scenarios. Answers were compared with those of a similar scenario-based survey administered to pediatric intensivists in 1997. Ninety-seven respondents were retained for the study, the majority from the United States, Canada, and France. In 2010, respondents reported that the mean (± SD) transfusion threshold was a hemoglobin level of 7.7 ± 1.0 g/dL for bronchiolitis, 8.1 ± 1.2 g/dL for trauma, 9.1 ± 1.2 g/dL for a tetralogy of Fallot repair, and 9.2 ± 1.0 g/dL for septic shock. For all clinical scenarios, there was a trend toward a more restrictive transfusion approach (a threshold ≤ 7 g/dL) in 2010 compared with 1997: a restrictive strategy was adopted by 55.7% of respondents in 2010 versus 37.0% in 1997 (p = 0.01) with the scenario of bronchiolitis, 8.3% versus 3.4% (p = 0.16) with septic shock, 38.1% versus 9.0% (p < 0.001) with trauma, and 16.0% versus 7.9% (p = 0.10) with tetralogy of Fallot repair. CONCLUSIONS Stated transfusion practice patterns of pediatric intensivists appear to be evolving toward a more restrictive approach two and a half years after the publication of the Transfusion Requirement in PICU trial. Incomplete implementation of new knowledge with regard to the safety of a restrictive transfusion approach in stable PICU patients is perplexing and requires further studies.

Abstract
OBJECTIVES Recent randomized clinical trials have shown the efficacy of a restrictive transfusion strategy in critically ill children. The impact of these trials on pediatric transfusion practice is unknown. Additionally, long-term trends in pediatric transfusion practice in the ICU have not been described. We assessed transfusion practice over time, including the effect of clinical trial publication. DESIGN Single-center, retrospective observational study. SETTING A 10-bed PICU in an urban academic medical center. PATIENTS Critically ill, nonbleeding children between the ages of 3 days and 14 years old, admitted to the University of Maryland Medical Center PICU between January 1, 1998, and December 31, 2009, excluding those with congenital heart disease, hemolytic anemia, and hemoglobinopathies. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS During the time period studied, 5,327 patients met inclusion criteria. Of these, 335 received at least one RBC transfusion while in the PICU. The overall proportion transfused declined from 10.5% in 1998 to 6.8% in 2009 (p = 0.007). Adjusted for acuity, the likelihood of transfusion decreased by calendar year of admission. In transfused patients, the pretransfusion hemoglobin level declined, from 10.5 g/dL to 9.3 g/dL, though these changes failed to meet statistical significance (p = 0.09). Neonatal age, respiratory failure, shock, multiple organ dysfunction syndrome, and acidosis were associated with an increased likelihood of transfusion in both univariate and multivariable models. CONCLUSIONS The overall proportion of patients transfused between 1998 and 2009 decreased significantly. The magnitude of the decrease varied over time, and no additional change in transfusion practice occurred after the publication of a major pediatric clinical trial in 2007. Greater illness acuity and younger patient age were associated with an increased likelihood of transfusion.

Abstract
BACKGROUND Studies have shown heterogeneity in red blood cell transfusion practices. Although plasma transfusion is common in intensive care, there are no data on plasma transfusion practices in pediatric critical care units. STUDY DESIGN AND METHODS A scenario-based survey was sent to 718 pediatric critical care physicians working in Europe, North America, Australia, and New Zealand. Respondents were asked to report their decisions regarding plasma transfusion practice with respect to four scenarios: pneumonia, septic shock, traumatic brain injury (TBI), and postoperative care after a Tetralogy of Fallot correction. RESULTS The response rate was 187 of 718 (26%); half of the responders worked in North America. The proportion of physicians who transfused plasma to nonbleeding patients, solely based on abnormal international normalized ratio (INR), varied from 66% for pneumonia to 84% for TBI (p < 0.001). In such nonbleeding patients, the median INR threshold that would trigger plasma transfusion was 2.5 for pneumonia and septic shock patients and 2.0 for TBI and the cardiac postoperative patients (p < 0.001). Minor bleeding, minor surgery, insertion of a femoral line, hypotension, abnormal activated partial thromboplastin time, thrombocytopenia, and anemia levels were important determinants of plasma transfusion, whereas none of the respondents' demographic characteristics were important. CONCLUSION More than two-thirds of responding pediatric critical care physicians prescribe plasma transfusions for nonbleeding critically ill children. Additionally, there is a significant variation in transfusion practice patterns with respect to plasma transfusion thresholds.

Abstract
Transfusion of blood products is a cornerstone in managing many critically ill children. Major improvements in blood product safety have not diminished the need for caution in transfusion practice. In this review, we aim to discuss the interplay between benefits and potential adverse effects of transfusion in critically ill children by including 65 papers, which were evaluated based on previously agreed selection criteria. Current practice on transfusing critically ill children is mainly founded on the basis of adult studies, common practices with cut-off values, and expert opinions, rather than evidence-based medicine. Paediatric patients have explicit physiological challenges and requirements to be addressed. Critically ill children often suffer from anaemia, have substantial iatrogenic blood loss with subsequent transfusions, and are at a higher risk of complications, often due to human errors. Transfusion in children is associated with increased morbidity. A restrictive transfusion strategy is not associated with increased morbidity. Thus, transfusion in paediatrics should be considered a high-risk treatment and requires individual clinical assessment. Current level of evidence support the notion that in most stable cases, despite high severity of illness (cyanotic children and neonates excluded), a restrictive haemoglobin threshold of 70 g/l (4.3 mmol/l) is no more harmful than to transfuse at a liberal trigger, e.g. haemoglobin 95 g/l (5.9 mmol/l). Thus, balanced against potential benefits and often its necessity, a restrictive approach may be appropriate due to the associated risks of transfusion.

Abstract
BACKGROUND Red blood cell (RBC) transfusions are common in the pediatric intensive care unit (PICU). However, there are no recent data on transfusion practices in the PICU. Our objective was to determine transfusion practice in the PICU, to compare this practice with that observed 10 years earlier, and to estimate the compliance to the recommendation of a large randomized clinical trial, the Transfusion Requirements in Pediatric Intensive Care Unit (TRIPICU) study. STUDY DESIGN AND METHODS This was a single-center prospective observational study over a 1-year period. Information was abstracted from medical charts. Determinants of transfusion were searched for daily until the first transfusion in transfused cases or until PICU discharge in nontransfused cases. The justifications for transfusions were assessed using a questionnaire. RESULTS Of 913 consecutive admissions, 842 were included. At least one RBC transfusion was given in 144 patients (17.1%). The mean hemoglobin (Hb) level before the first transfusion was 77.3 ± 27.2 g/L. The determinants of a first transfusion event retained in the multivariate analysis were young age (<12 months), congenital cardiopathy, lowest Hb level of not more than 70 g/L, severity of illness, and some organ dysfunctions. The three most frequently quoted justifications for RBC transfusion were a low Hb level, intent to improve oxygen delivery, and hemodynamic instability. The main recommendation of the TRIPICU study was applied in 96.4% of the first transfusion events. CONCLUSIONS RBC transfusions are frequent in the PICU. Young age, congenital heart disease, low Hb level, severity of illness, and some organ dysfunctions are significant determinants of RBC transfusions in the PICU. Most first transfusion events were prescribed according to recent recommendations.

Abstract
Early recognition and treatment of pediatric shock, regardless of cause, decreases mortality and improves outcome. In addition to the conventional parameters (eg, heart rate, systolic blood pressure, urine output, and central venous pressure), biomarkers and noninvasive methods of measuring cardiac output are available to monitor and treat shock. This article emphasizes how fluid resuscitation is the cornerstone of shock resuscitation, although the choice and amount of fluid may vary based on the cause of shock. Other emerging treatments for shock (ie, temperature control, extracorporeal membrane oxygenation/ventricular assist devices) are also discussed.

Abstract
OBJECTIVE To test the hypothesis that transfusion of leukocyte-depleted RBC preparations within the first 48 hours of PICU stay was independently associated with prolonged duration of mechanical ventilation, irrespective of surgery type and disease severity. DESIGN Retrospective, observational study. SETTING Single-center PICU in The Netherlands. PATIENTS Children less than 18 years consecutively admitted after pediatric cardiac surgery between February 2007 and February 2010. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Data from 335 patients were used for analysis of whom 86 (25.7%) were transfused during the first 48 hours of PICU stay. Duration of mechanical ventilation (115 ± 19 hours vs. 25 ± 4 hours, p < 0.001) was longer among transfused patients. Ventilator-associated pneumonia (10.5% vs. 1.6%, odds ratio 7.2; 95% confidence interval 1.92-32.47; p < 0.001) was more frequent among transfused patients. New acute kidney injury after 48 hours of PICU admission (23.9% vs. 15.4%, p = 0.18) and mortality were comparable (2.3% vs. 4%, p = 0.16). The number of discrete transfusion events was significantly correlated with the duration of mechanical ventilation (Spearman's rho 0.617, p < 0.001). Transfusion remained independently associated with prolonged duration of mechanical ventilation after adjusting for confounders using Cox proportional hazards regression analysis. CONCLUSIONS Transfusion of leukocyte-depleted RBCs within the first 48 hours of PICU stay after cardiac surgery is independently associated with prolonged duration of mechanical ventilation.

Abstract
Until recovery of hematopoiesis, pediatric hematopoietic stem cell transplant (HSCT) patients are dependent on red blood cell and platelet transfusions to avoid the complications associated with anemia and thrombocytopenia, respectively. Despite the fact that these patients are high utilizers of blood components, there are no evidence-based guidelines regarding optimal transfusion practices in this patient population. A web-based survey was designed to examine current transfusion thresholds used by institutions that perform pediatric HSCT. This survey was sent to department directors identified through the Children's Oncology Group directory with a response rate of 69%. The majority of institutions use 8 g/dL as the hemoglobin threshold for red blood cell transfusions (60%), but a significant minority use 7 g/dL (25%). With respect to platelet transfusion thresholds, 47% of respondents report using 20×10/L and 44% use 10×10/L. Respondents were also asked about specific clinical scenarios that would prompt an increase in a patient's threshold. This survey revealed that there is variation in transfusion practices among pediatric HSCT institutions with respect to both baseline transfusion threshold and what prompts an increase in threshold. Future clinical trials are needed to determine optimal transfusion thresholds in pediatric HSCT patients, which can lead to improved standardization in practices.

Abstract
Resuscitation of children and neonates with severe or refractory bleeding due to surgery or trauma often requires massive transfusion (MT). Findings from recent studies have led to a better understanding of the complex pathophysiology in massive haemorrhage and the effects of MT on haemostasis. Current management of the massively bleeding adult patient has evolved over the past few decades, shifting to early transfusion of products in a balanced ratio as part of MT protocols (MTPs). Paediatric data on successful management of MT are limited and the optimal transfusion approach is currently unknown, leading to practice variability among institutions, depending on resource availability and patients' needs. Here, we review new important concepts in the biology of massive bleeding and MT, outline important management principles and current practices, and highlight available relevant adult and paediatric data.

Abstract
BACKGROUND Red blood cell (RBC) transfusion is common in intensive care unit (ICU) patients and is associated with complications that appear related to the duration of blood storage. We hypothesize that hemolysis of stored RBCs results in increases in the availability of non-heme-bound iron, which inhibits macrophage activation. STUDY DESIGN AND METHODS RBCs were sampled at multiple time points to evaluate hemolysis and iron release. Activation of THP-1 monocytic cells was assessed in the presence of plasma from aged RBCs. Age of transfused blood in our pediatric intensive care unit (PICU) from 2001 to 2006 was analyzed to assess relevance to our patient population. RESULTS Hemolysis increased significantly during storage time as demonstrated by increases in free heme and hemoglobin. While there was a trend toward elevated levels of non-heme-bound iron, this was not significant (p = 0.07). THP-1 cell activation was inhibited by exposures to both plasma and a ferric compound; the effect of plasma on macrophage activation was not reversed by the iron chelator desferroxamine. Thirty-one percent of our PICU patients received blood older than 2 weeks. CONCLUSION Hemolysis products increased significantly over time in our stored RBCs. Ferric compounds and plasma from stored blood inhibit THP-1 cell activation. Plasma inhibition does not appear to be due primarily to increased iron. Further studies are needed to define the inhibitory effect of stored blood plasma on macrophage function. Complications related to blood storage are relevant to our PICU patients.

Abstract
The results of the Transfusion Requirements in Pediatric Intensive Care Unit study suggest that a red blood cell transfusion is not required in stable or stabilized pediatric intensive care unit children as long as their hemoglobin level is >7 g/dL. Subgroup analyses suggest that this recommendation is also adequate for stable critically ill children with a high severity of illness, respiratory dysfunction, acute lung injury, sepsis, neurological dysfunction, severe head trauma, or severe trauma, and during the postoperative period, for noncyanotic patients older than 28 days. A small randomized clinical trial suggests that a hemoglobin level of 9 g/dL is safe in the postoperative care of children with single-ventricle physiology undergoing cavopulmonary connection. Although there is consensus that blood is clearly indicated for the treatment of hemorrhagic shock, the clinical determinants that should prompt pediatric intensivists to prescribe a red blood cell transfusion to unstable PICU children are not well characterized.

Abstract
OBJECTIVES This article summarizes the current data on packed red blood cell transfusion in the pediatric intensive care unit setting to help providers make evidence-based decisions regarding packed red blood cell transfusions. DATA SOURCES Review of the literature, including PubMed, citations from relevant articles, and some articles that have been particularly relevant in adult critical care practice regarding packed red blood cell transfusion. CONCLUSIONS The use of packed red blood cell transfusions is common in the pediatric intensive care unit setting. However, until recently there have been little data to guide providers in this practice. Studies in adult intensive care units have shown less favorable outcomes in patients who received packed red blood cell transfusions. This has led to renewed questioning of the practice of packed red blood cell transfusion in critically ill pediatric patients. New data indicate that using a hemoglobin transfusion threshold of >7 g/dL does not yield improved outcomes. Furthermore, smaller studies have suggested that pediatric intensive care unit patients may be at an increased risk for morbidity and mortality when undergoing transfusion.

Abstract
Patients in the pediatric intensive care unit (PICU) frequently receive transfusions of blood products. While these therapies are often beneficial, they can be associated with significant, yet often overlooked, risks. Clinical guidelines for blood product transfusions must be well defined in order to prevent misuse of this limited resource. It is important for the intensivist to have a thorough understanding of the indications for specific blood products, and the transfusion needs of particular patient populations.

Abstract
OBJECTIVES This study aimed to describe the professional practices in pediatric transfusion to assess the accuracy of transfusion guidelines in children. METHODS The study retrospectively analyzed the characteristics of all the pediatric transfusions prescribed in the Clermont-Ferrand (France) university hospital center over 1 year and determined whether they conformed to the national guidelines. RESULTS One thousand six hundred and seven blood products were delivered to 233 children (806 red cell units, 670 platelet units, and 131 plasma units), accounting for 5.3% of the center's whole blood products. Transfusions were mainly prescribed by the oncohematology unit (68.2%), the intensive care unit (15.4%), and for surgery (10.2%). Ten adverse events were reported in eight patients (0.6% of transfusions). The prescription conformed to the national guidelines in 35.9%, 41.6%, and 80.9% of the red blood cell, platelet, and plasma unit transfusions, respectively. Nonconformity was mainly due to abusive irradiation and "cytomegalovirus seronegative" specifications. CONCLUSION Malignancies, intensive care, and surgery are the main indications for transfusion in children. Substantial discrepancy between recommendations and actual practices was observed. This illustrates the variability of risk evaluation. This should be made simpler by the use of photochemical pathogen inactivation techniques.

Abstract
OBJECTIVES In children with severe sepsis or septic shock, the optimal red blood cell transfusion threshold is unknown. We analyzed the subgroup of patients with sepsis and transfusion requirements in a pediatric intensive care unit study to determine the impact of a restrictive vs. liberal transfusion strategy on clinical outcome. DESIGN Subgroup analysis of a prospective, multicenter, randomized, controlled trial. SETTING Multicenter pediatric critical care units. PATIENTS Stabilized critically ill children (mean systemic arterial pressure >2 sd below normal mean for age and cardiovascular support not increased for at least 2 hrs before enrollment) with a hemoglobin ≤ 9.5 g/dL within 7 days after pediatric critical care unit admission. INTERVENTIONS One hundred thirty-seven stabilized critically ill children with sepsis were randomized to receive red blood cell transfusion if their hemoglobin decreased to either <7.0 g/dL (restrictive group) or 9.5 g/dL (liberal group). MEASUREMENTS AND MAIN RESULTS In the restrictive group (69 patients), 30 patients did not receive any red blood cell transfusion, whereas only one patient in the liberal group (68 patients) never underwent transfusion (p < .01). No clinically significant differences were found for the occurrence of new or progressive multiple organ dysfunction syndrome (18.8% vs. 19.1%; p = .97), for pediatric critical care unit length of stay (p = .74), or for pediatric critical care unit mortality (p = .44) in the restrictive vs. liberal group. CONCLUSIONS In this subgroup analysis of children with stable sepsis, we found no evidence that a restrictive red cell transfusion strategy, as compared to a liberal one, increased the rate of new or progressive multiple organ dysfunction syndromes. Furthermore, a restrictive transfusion threshold significantly reduced exposure to blood products. Our data suggest that a hemoglobin level of 7.0 g/dL may be safe stabilized for children with sepsis, but further studies are required to support this recommendation.

Abstract
OBJECTIVES To describe a population of children that received red blood cell transfusions. METHODS A retrospective observational study carried out at the Pediatric Intensive Care Unit of the Instituto da Criança of Hospital das Clínicas of Faculdade de Medicina of Universidade de São Paulo in 2004, with children that received red blood cell transfusions. RESULTS Transfusion of red blood cells was performed in 50% of the patients hospitalized. Median age was 18 months, and the primary motive for admission was respiratory insufficiency (35%). Underlying disease was present in 84% of the cases and multiple organ and system dysfunction in 46.2%. The median value of pretransfusion hemoglobin concentration was 7.8 g/dL. Transfused patients were undergoing some form of therapeutic procedure in 82% of the cases. CONCLUSIONS Red blood cell transfusions are performed at all ages. Hemoglobin concentration and hematocrit rate are the primary data used to indicate these transfusions. The values of arterial serum lactate and SvO2were seldom used. Most patients transfused were submitted to some form of therapeutic procedure, and in many cases, transfusions were carried out in patients with multiple organ and system dysfunctions.

Abstract
OBJECTIVE Timely provision of evidence-based recommendations through computerized physician order entry with clinical decision support may improve use of red blood cell transfusions (RBCTs). METHODS We performed a cohort study with historical controls including inpatients admitted between February 1, 2008, and January 31, 2010. A clinical decision-support alert for RBCTs was constructed by using current evidence. RBCT orders resulted in assessment of the patient's medical record with prescriber notification if parameters were not within recommended ranges. Primary end points included the average pretransfusion hemoglobin level and the rate of RBCTs per patient-day. RESULTS In total, 3293 control discharges and 3492 study discharges were evaluated. The mean (SD) control pretransfusion hemoglobin level in the PICU was 9.83 (2.63) g/dL (95% confidence interval [CI]: 9.65-10.01) compared with the study value of 8.75 (2.05) g/dL (95% CI: 8.59-8.90) (P < .0001). The wards' control value was 7.56 (0.93) g/dL (95% CI: 7.47-7.65), the study value was 7.14 (1.01) g/dL (95% CI: 6.99-7.28) (P < .0001). The control PICU rate of RBCTs per patient-day was 0.20 (0.11) (95% CI: 0.13-0.27), the study rate was 0.14 (0.04) (95% CI: 0.11-0.17) (P = .12). The PICU's control rate was 0.033 (0.01) (95% CI: 0.02-0.04), and the study rate was 0.017 (0.007) (95% CI: 0.01-0.02) (P < .0001). There was no difference in mortality rates across all cohorts. CONCLUSIONS Implementation of clinical decision-support alerts was associated with a decrease in RBCTs, which suggests improved adoption of evidence-based recommendations. This strategy might be widely applied to promote timely adoption of scientific evidence.

Abstract
BACKGROUND There are so far no existing consensus guidelines regarding red blood cell transfusion during pediatric surgery, and there is a little information regarding red blood cell transfusion policy among pediatric anesthesiologists. OBJECTIVES To determine the transfusion threshold and the volumes of packed red blood cell (PRBC) transfusion among French-speaking pediatric anesthesiologists. MATERIALS AND METHODS A questionnaire of case scenarios was sent to active members of the French Language Society of Pediatrics Anesthesiologists (ADARPEF). RESULTS Of the 324 active members of the ADARPEF, 175 (54%) completed the questionnaire. The threshold for blood transfusion varied from 6 to 12 g·dl(-1) depending on the scenario. The hemoglobin threshold for blood transfusion and the volume of blood transfused vary among ADARPEF physicians, for the same class of patients. The median [95% CI] hemoglobin threshold for starting blood transfusion was 7.9 [6.9-8.9], 7.3 [6.4-8.2], and 8.1 [7.0-9.2] g·dl(-1) in the pre-, intra-, and postoperative phase, respectively. The median [95% CI] PRBC volume transfused was 11.7 [6.6-16.8] ml·kg(-1), and the median hemoglobin target was 11.3 [9.8-12.8] g·dl(-1). Physicians ranked age (79%), clinical tolerance of anemia (99%), underlying medical conditions (95%), hemodynamic instability (89%), hemostasis disorder (86%), and sepsis (79%) as the most significant factors affecting their transfusion decisions. Most pediatric anesthesiologists (89%) measure the hemoglobin level before PRBC transfusion. CONCLUSIONS This survey identifies significant differences in transfusion practice patterns among pediatric anesthesiologists with a median transfusion threshold of 7.6 [6.6-8.6] g·dl(-1) and a median PRBC volume transfusion of 11.7 [16.8-6.6] ml·kg(-1).
