Abstract
Few data describe pediatric patients who receive massive transfusion for life-threatening hemorrhage (LTH) while on extracorporeal membrane oxygenation (ECMO). We present a retrospective secondary analysis of a multicenter prospective observational study to describe resource utilization and mortality in pediatric patients with LTH while on ECMO. Children who were on ECMO during an LTH were compared to children with LTH who were not on ECMO. Primary outcomes were volumes of blood products administered and 28 day mortality. Comparisons were assessed by two-sided Fisher's exact test or Wilcoxon rank sum test. A total of 449 children, including 36 on ECMO, were included. Compared to those not on ECMO, children on ECMO received a higher volume of blood products (110 [50-223] vs . 59 [28-113]) ml/kg, p = 0.002) and were more likely to receive antifibrinolytic therapy (39% vs . 10%, p < 0.001). Blood product ratios were similar. Extracorporeal membrane oxygenation patients had higher 28 day mortality (64% vs. 35%, p = 0.001), although 24 hour mortality was similar (17% vs . 23%, p = 0.5). In conclusion, children on ECMO with LTH experience high resource utilization and 28 day mortality. Studies are needed to identify children at risk for LTH and to evaluate ECMO-specific treatment strategies.

Abstract
Sublethal damage to red blood cells (RBCs) during extracorporeal life support (ECLS) may lead to RBC loss. Using flow cytometry, phosphatidylserine-positive (PhS+) RBCs and RBC extracellular vesicles were quantified as measures of sublethal RBC injury in 41 pediatric ECLS runs, stored RBC units, and normal adult subjects. We estimated the clearance half-life of PhS+ RBCs and compared the rates of RBC loss during pediatric ECLS due to phlebotomy, intravascular hemolysis, and extravascular clearance of PhS+ RBCs. Extracorporeal life support patients had 0.9% PhS+ RBCs, sixfold higher than normal subjects (p < 0.0001). Phosphatidylserine-positive RBCs were increased in stored RBC units (twofold in whole blood derived units, p = 0.0013; 12-fold in apheresis RBC units, p < 0.0001). Phosphatidylserine-positive RBCs were cleared with an average half-life of 15 hours. During ECLS, PhS+ RBC clearance accounted for 7% of RBC loss (1-60%), phlebotomy 12%, and intravascular hemolysis 12%. Increasing PhS+ RBCs occurred in 40% of patients that died on ECLS. Red blood cell extracellular vesicles, another marker of red cell injury/activation, were elevated fivefold during ECLS. Phosphatidylserine exposure on RBCs is increased during ECLS, marking these cells for extravascular clearance with a half-life of ~15 hours and accounting for ~7% of RBC loss.

Abstract
BACKGROUND This meta-analysis aimed to explore the impact of red blood cell (RBC) transfusion on mortality during extracorporeal membrane oxygenation (ECMO). Previous studies investigated the prognostic impact of RBC transfusion during ECMO on the risk of mortality, but no meta-analysis has been published before. METHODS The PubMed, Embase, and the Cochrane library were systematically searched for papers published up to 13 December 2021, using the MeSH terms "ECMO", "'Erythrocytes", and "Mortality" to identify meta-analyses. Total or daily RBC transfusion during ECMO and mortality were examined. RESULTS The random-effect model was used. Eight studies (794 patients, including 354 dead) were included. The total volume of RBC was associated with higher mortality standardized weighted difference (SWD = -0.62, 95% CI: -1.06,-0.18, p = .006; I2 = 79.7%, Pheterogeneity = 0.001). The daily volume of RBC was associated with higher mortality (SWD = -0.77, 95% CI: -1.11,-0.42, p < .001; I2 = 65.7%, Pheterogeneity = 0.020). The total volume of RBC was associated with mortality for venovenous (VV) (SWD = -0.72, 95% CI: -1.23, -0.20, p = .006) but not venoarterial ECMO (p = .126) or when reported together (p = .089). The daily volume of RBC was associated with mortality for VV (SWD = -0.72, 95% CI: -1.18, -0.26, p = 0.002; I2 = 0.0%, Pheterogeneity = 0.642) and venoarterial (SWD = -0.95, 95% CI: -1.32, -0.57, p < .001) ECMO, but not when reported together (p = .067). The sensitivity analysis suggested the robustness of the results. CONCLUSION When considering the total and daily volumes of RBC transfusion during ECMO, the patients who survived received smaller total and daily volumes of RBC transfusion. This meta-analysis suggests that RBC transfusion might be associated with a higher risk of mortality during ECMO.

Abstract
BACKGROUND Patients who receive extracorporeal membrane oxygenation (ECMO) support require substantial transfusions. Red blood cell (RBC) and platelet (PLT) transfusions have been reported to be associated with adverse outcomes in ECMO patients. However, little is known about whether the transfusion of fresh frozen plasma (FFP) is associated with mortality and morbidity among patients receiving ECMO. The aim of this study was to examine the relationship between FFP transfusion and mortality in ECMO patients and assess risk factors for the transfusion of FFP. METHODS The clinical parameters of 116 ECMO patients were collected. The machine learning approach of the Boruta algorithm was employed to select the variables associated with ECMO patients' in-hospital mortality. Univariate and multivariate logistic regression analyses were applied to identify the association between the selected variables and in-hospital mortality. Spearman correlation and backwards stepwise multiple linear regression analyses were used to examine parameters contributing to FFP transfusion. RESULTS Among the 116 patients who received ECMO support, the in-hospital mortality was 32.8%. The median FFP (mL/kg/d) transfusion was higher in dead patients (5.07, IQR 1.78-8.90) when compared to alive patients (2.16, IQR 0.79-4.66) (p = 0.007). After adjustment for confounders, FFP transfusion (mL/kg/d) was associated with in-hospital mortality (OR 1.09, 95% CI, 1.01-1.18; p = 0.035). Further analysis found that higher activated partial thromboplastin time (APTT), higher levels of uric acid (UA) and lower PLT counts were significant risk factors for FFP transfusion, with estimated values of 0.06 (95% CI, 0.02-0.11; p = 0.009), 0.01 (95% CI, 0.00-0.02; p = 0.003) and -0.03 (95% CI, -0.05--0.01; p = 0.007), respectively. CONCLUSION FFP transfusion is markedly associated with in-hospital mortality among patients receiving ECMO, and higher APTT, higher levels of UA and lower PLT counts are risk factors for FFP transfusion. This suggests that better management of patients' coagulation system and kidney function may reduce the utilization of FFP, thus improving ECMO patient outcomes.

Abstract
Extracorporeal Membrane Oxygenation (ECMO) is an important tool for managing critically ill neonates. Bleeding and thrombotic complications are common and significant. An understanding of ECMO physiology, its interactions with the unique neonatal hemostatic pathways, and appreciation for the distinctive risks and benefits of neonatal transfusion as it applies to ECMO are required. Currently, there is variability regarding transfusion practices, related to changing norms and a lack of high-quality literature and trials. This review provides an analysis of the neonatal ECMO transfusion literature and summarizes available best practice guidelines.

Abstract
BACKGROUND Pediatric patients on extracorporeal membrane oxygenation (ECMO) often receive repeated red blood cell (RBC) transfusions. This study aims to quantify and characterize causes of RBC loss on ECMO. METHODS This retrospective, single-center, observational study includes 91 ECMO patients (age 1 day-20 years). An RBC loss index (RLI), equal to ml RBCs lost per liter of patient + circuit volume per hour, was calculated from the changes in hematocrit and transfused RBCs. To measure the contribution of RBC injury/activation, RBC extracellular vesicle (REV) generation was measured by flow cytometry. RESULTS Median RLI on ECMO was 1.9 ml/L/h, 13-fold higher than normal RBC production rate (0.15 ml/L/h) and equivalent to a 4.6 drop in hematocrit/day. Median RBC loss was higher in patients who died (2.95 ml/L/h) versus survived (1.70 ml/L/h, p = .0008). RLI correlated with transfusion rate (r2 = 0.71); however, transfusion rate (ml/kg) underestimated RBC loss in patients with large changes in hematocrit and over-estimated RBC loss in neonates where the circuit volume is greater than the patient blood volume. In non-bleeding patients, intravascular hemolysis represented 16% of total RBC loss and diagnostic phlebotomy 24%, suggesting that ~60% of RBC loss was due to other causes. REV generation was increased sevenfold to ninefold during ECMO. DISCUSSION RLI (ml/L/h) is a more reliable quantitative indicator of RBC loss than transfusion rate (ml/kg) for pediatric patients on ECMO. Phlebotomy and intravascular hemolysis only account for 40% of RBC loss in non-bleeding ECMO patients. High REV generation suggests sublethal damage and extravascular clearance may be a cause of RBC loss on ECMO.

Abstract
BACKGROUND Blood product transfusions are necessary for critically ill neonates on extracorporeal membrane oxygenation (ECMO). Transfusions are administered in response to unstudied arbitrary thresholds and may be associated with adverse outcomes. The objective of this study was to identify relationships between blood product components and mortality in neonates receiving ECMO support for respiratory indications. STUDY DESIGN AND METHODS A retrospective review of neonates receiving ECMO for respiratory indications from 2002 to 2019 from a single quaternary-referral neonatal intensive care unit (NICU). Demographic and outcome data and transfusion volume (ml/kg/day) were harvested from the medical record, and baseline mortality risk was assessed using NEO-RESCUERS scores. The association between volume of red blood cells (RBC), platelet, plasma transfusion rates (ml/kg/day), and mortality on ECMO were assessed after adjustment for NEO-RESCUERS score. Cox proportional hazards (CPH) competing risk model was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for each variable and mortality outcome. MEASUREMENTS AND MAIN RESULTS Among 248 neonates undergoing ECMO for respiratory failure, overall survival was 93%. RBC, platelet, and plasma volume were highly associated with mortality during ECMO in an unadjusted model. After adjusting for NEO-RESCUERS score, RBC volume was associated with increased mortality risk (HR 1.013, 95% CI 1.004-1.022, p = .0043), but platelet and plasma volume were not associated with mortality. CONCLUSIONS RBC, but not platelet or plasma volume, is associated with mortality in neonates on ECMO. Our findings refute previous studies demonstrating an association between platelet volume and mortality for neonates on ECMO.

Abstract
Extracorporeal circulation (ECC) systems, including cardiopulmonary bypass, and extracorporeal membrane oxygenation have been an irreplaceable part of the cardiothoracic surgeries, and treatment of critically ill patients with respiratory and/or cardiac failure for more than half a century. During the recent decades, the concept of extracorporeal circulation has been extended to isolated machine perfusion of the donor organ including thoracic organs (ex-situ organ perfusion, ESOP) as a method for dynamic, semi-physiologic preservation, and potential improvement of the donor organs. The extracorporeal life support systems (ECLS) have been lifesaving and facilitating complex cardiothoracic surgeries, and the ESOP technology has the potential to increase the number of the transplantable donor organs, and to improve the outcomes of transplantation. However, these artificial circulation systems in general have been associated with activation of the inflammatory and oxidative stress responses in patients and/or in the exposed tissues and organs. The activation of these responses can negatively affect patient outcomes in ECLS, and may as well jeopardize the reliability of the organ viability assessment, and the outcomes of thoracic organ preservation and transplantation in ESOP. Both ECLS and ESOP consist of artificial circuit materials and components, which play a key role in the induction of these responses. However, while ECLS can lead to systemic inflammatory and oxidative stress responses negatively affecting various organs/systems of the body, in ESOP, the absence of the organs that play an important role in oxidant scavenging/antioxidative replenishment of the body, such as liver, may make the perfused organ more susceptible to inflammation and oxidative stress during extracorporeal circulation. In the present manuscript, we will review the activation of the inflammatory and oxidative stress responses during ECLP and ESOP, mechanisms involved, clinical implications, and the interventions for attenuating these responses in ECC.

Abstract
Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is used to support patients with reversible cardiopulmonary insufficiency. Although it is a lifesaving technology, bleeding, inflammation, and thrombosis are well-described complications of ECMO. Adult porcine models of ECMO have been used to recapitulate the physiology and hemostatic consequences of ECMO cannulation in adults. However, these models lack the unique physiology and persistence of fetal forms of coagulation factors and fibrinogen as in human infants. We aimed to describe physiologic and coagulation parameters of piglets cannulated and supported with VA-ECMO. Four healthy piglets (5.7-6.4 kg) were cannulated via jugular vein and carotid artery by cutdown and supported for a maximum of 20 hours. Heparin was used with a goal activated clotting time of 180-220 seconds. Arterial blood gas (ABG) was performed hourly, and blood was transfused from an adult donor to maintain hematocrit (Hct) > 24%. Rotational thromboelastometry (ROTEM) was performed at seven time points. All animals achieved adequate flow with a patent circuit throughout the run (pre- and post-oxygenator pressure gradient <10 mmHg). There was slow but significant hemorrhage at cannulation, arterial line, and bladder catheter sites. All animals required the maximum blood transfusion volume available. All animals became anemic after exhaustion of blood for transfusion. ABG showed progressively declining Hct and adequate oxygenation. ROTEM demonstrated decreasing fibrin-only ROTEM (FIBTEM) clot firmness. Histology was overall unremarkable. Pediatric swine are an important model for the study of pediatric ECMO. We have demonstrated the feasibility of such a model while providing descriptions of physiologic, hematologic, and coagulation parameters throughout. Weak whole-blood clot firmness by ROTEM suggested defects in fibrinogen, and there was a clinical bleeding tendency in all animals studied. This model serves as an important means to study the complex derangements in hemostasis during ECMO.

Abstract
Extracorporeal membrane oxygenation was first successfully achieved in 1975 in a neonate with meconium aspiration. Neonatal extracorporeal membrane oxygenation has expanded to include hemodynamic support in cardiovascular collapse before and after cardiac surgery, medical heart disease, and rescue therapy for cardiac arrest. Advances in pump technology, circuit biocompatibility, and oxygenators efficiency have allowed extracorporeal membrane oxygenation to support neonates with increasingly complex pathophysiology. Contraindications include extreme prematurity, extremely low birth weight, lethal chromosomal abnormalities, uncontrollable hemorrhage, uncontrollable disseminated intravascular coagulopathy, and severe irreversible brain injury. The future will involve collaboration to guide and evolve evidence-based practices for this life-sustaining therapy.

Abstract
BACKGROUND Neonates receiving extracorporeal membrane oxygenation (ECMO) support are transfused large volumes of red blood cells (RBCs) and platelets (PLTs). Transfusions are often administered in response to specific, but largely unstudied thresholds. The aim of this study is to examine the relationship between RBC and PLT transfusion rates and mortality in neonates receiving ECMO support. STUDY DESIGN AND METHODS We retrospectively examined outcomes of neonates receiving ECMO support in the neonatal intensive care unit (NICU) for respiratory failure between 2010 and 2016 at a single quaternary-referral NICU. We examined the association between RBC and PLT transfusion rate (mL per kg per day) and in-hospital mortality, adjusting for confounding by using a validated composite baseline risk score (Neo-RESCUERS). RESULTS Among the 110 neonates receiving ECMO support, in-hospital mortality was 28%. The median RBC transfusion rate (mL/kg/d) after cannulation was greater among non-survivors, compared to survivors: 12.4 (IQR 9.3-16.2) versus 7.3 (IQR 5.1-10.3), p < 0.001. Similarly, PLT transfusion rate was greater among non-survivors: 22.9 (9.3-16.2) versus 12.1 (8.4-20.1), p = 0.02. After adjusting for baseline mortality risk, both RBC transfusion (adjusted relative risk per 5 mL/kg/d increase: 1.33; 95% CI 1.05-1.69, p = 0.02) and PLT transfusion (adjusted relative risk per 5 mL/kg/d increase: 1.12; 95% CI 1.02-1.23, p = 0.02) were both associated with in-hospital mortality. CONCLUSIONS RBC and PLT transfusion rates are associated with in-hospital mortality among neonates receiving ECMO. These data provide a basis for future studies evaluating more restrictive transfusion practices for neonates receiving ECMO support.

Abstract
OBJECTIVES To quantify and identify factors associated with large RBC exposure in children supported with extracorporeal membrane oxygenation. DESIGN Retrospective cohort study. SETTING Single tertiary care children's hospital. PATIENTS One-hundred twenty-two children supported with extracorporeal membrane oxygenation for greater than 12 hours during January 1, 2015, to December 31, 2016. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Clinical, laboratory, and survival data were obtained from medical records. Only data from patients' first extracorporeal membrane oxygenation run were used. The primary outcome was RBC volume exposure during extracorporeal membrane oxygenation (mL/kg/d). Patients with RBC exposure volume greater than 75th percentile were categorized as "high RBC use" patients. A "bleeding day" was identified if mediastinum or cannula sites were explored and/or Factor VIIa administration, gastrointestinal, pulmonary, or intracranial hemorrhages occurred. Median age was 0.3 years (interquartile range, 0-3 yr). Congenital heart disease (n = 56; 46%) was the most common diagnosis. Median RBC volume transfused during extracorporeal membrane oxygenation was 39 mL/kg/d (interquartile range, 21-66 mL/kg/d). High RBC use patients were more likely be supported by venoarterial extracorporeal membrane oxygenation (100 vs 76%; p = 0.006), have congenital heart disease (68 vs 39%; p = 0.02), and experience bleeding (33 vs 11% d; p < 0.001). High RBC use patients showed a trend toward higher in-hospital mortality (58 vs 37%; p = 0.07). In the multivariable analysis, younger age (-9% per year; 95% CI, -10% to -7%; p < 0.001), more blood draws per day (+8%; 95% CI, 6-11%; p < 0.001), and higher proportion of bleeding days (+22% per 10% increase; 95% CI, 16-29%; p < 0.001) were associated with larger RBC exposure (model R = 0.66). CONCLUSIONS Bleeding during extracorporeal membrane oxygenation, frequent laboratory draws, and younger age were associated with increased RBC exposure during extracorporeal membrane oxygenation. Higher transfusion volume was associated with increased mortality.

Abstract
OBJECTIVES To determine RBC transfusion practice and relationships between RBC transfusion volume and mortality in infants and children treated with extracorporeal membrane oxygenation. DESIGN Secondary analysis of a multicenter prospective observational study. SETTING Eight pediatric institutions within the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Collaborative Pediatric Critical Care Research Network. PATIENTS Patients age less than 19 years old treated with extracorporeal membrane oxygenation at a participating center. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Clinical data and target hemoglobin or hematocrit values (if set) were recorded daily by trained bedside extracorporeal membrane oxygenation specialists and research coordinators. Laboratory values, including hemoglobin and hematocrit, were recorded daily using the value obtained closest to 8:00 AM. RBC transfusion was recorded as total daily volume in mL/kg. Multivariable logistic regression was used to determine the relationship between RBC transfusion volume and hospital mortality, accounting for potential confounders. Average goal hematocrits varied across the cohort with a range of 27.5-41.3%. Overall, actual average daily hematocrit was 36.8%, and average RBC transfusion volume was 29.4 mL/kg/d (17.4-49.7 mL/kg/d) on extracorporeal membrane oxygenation. On multivariable analysis, each additional 10 mL/kg/d of RBC transfusion volume was independently associated with a 9% increase in odds of hospital mortality (adjusted odds ratio, 1.09 [1.02-1.16]; p = 0.009). CONCLUSIONS In this multicenter cohort of pediatric extracorporeal membrane oxygenation patients, daily hematocrit levels were maintained at normal or near-normal values and RBC transfusion burden was high. RBC transfusion volume was independently associated with odds of mortality. Future clinical studies to identify optimum RBC transfusion thresholds for pediatric extracorporeal membrane oxygenation are urgently needed.

Abstract
OBJECTIVES To describe functional status at hospital discharge for neonatal and pediatric patients treated with extracorporeal membrane oxygenation, and identify factors associated with functional status and mortality. DESIGN Secondary analysis of observational data collected by the Collaborative Pediatric Critical Care Research Network between December 2012 and September 2014. SETTING Eight hospitals affiliated with the Collaborative Pediatric Critical Care Research Network. PATIENTS Patients were less than 19 years old and treated with extracorporeal membrane oxygenation. INTERVENTIONS Functional status was evaluated among survivors using the Functional Status Scale. Total Functional Status Scale scores range from 6 to 30 and are categorized as 6-7 (good), 8-9 (mildly abnormal), 10-15 (moderately abnormal), 16-21 (severely abnormal), and greater than 21 (very severely abnormal). MEASUREMENTS AND MAIN RESULTS Of 514 patients, 267 (52%) were neonates (≤ 30 d old). Indication for extracorporeal membrane oxygenation was respiratory for 237 (46%), cardiac for 207 (40%), and extracorporeal cardiopulmonary resuscitation for 70 (14%). Among 282 survivors, 89 (32%) had good, 112 (40%) mildly abnormal, 67 (24%) moderately abnormal, and 14 (5%) severely or very severely abnormal function at hospital discharge. Among neonates, development of renal failure and longer hospitalization were independently associated with worse Functional Status Scale. Chronic conditions, prematurity, venoarterial extracorporeal membrane oxygenation, increased red cell transfusion in the first 24 hours of extracorporeal membrane oxygenation, and longer extracorporeal membrane oxygenation duration were independently associated with mortality. Among pediatric patients, chronic neurologic conditions, tracheostomy or home ventilator, extracorporeal cardiopulmonary resuscitation, hepatic dysfunction, and longer ICU stay were independently associated with worse Functional Status Scale. Chronic cardiac conditions, hepatic dysfunction, and neurologic or thrombotic complications were independently associated with mortality. Achieving blood lactate concentration less than or equal to 2 mmol/L during extracorporeal membrane oxygenation was independently associated with survival in both neonatal and pediatric patients. CONCLUSIONS In this study, about half of extracorporeal membrane oxygenation patients survived with good, mildly abnormal, or moderately abnormal function at hospital discharge. Patient and extracorporeal membrane oxygenation-related factors are associated with functional status and mortality.

Abstract
BACKGROUND The objective of this study was to assess complications and patient outcomes associated with a lower reflexive red blood cell (RBC) transfusion threshold for neonates undergoing extracorporeal membrane oxygenation (ECMO) for hypoxic respiratory failure. STUDY DESIGN AND METHODS A retrospective cohort study was conducted at a single tertiary neonatal intensive care unit of neonates undergoing ECMO support for refractory hypoxic respiratory failure for more than 24 hours between December 2009 and December 2014. Seventy-two neonates received ECMO support for hypoxic respiratory failure for longer than 24 hours during the study period. Patient cohorts were determined based on transfusion threshold of hematocrit (Hct) level of less than 40% (December 2009-October 2012) and Hct level of less than 35% (November 2012-December 2014). RESULTS Patients who had a lower threshold for transfusion (Hct < 35) had a lower mean Hct (38.3% vs. 41.4%, p < 0.0001) and received less total RBC transfusion volume (10.4 mL/kg/day vs. 13.3 mL/kg/day, p = 0.002) while undergoing ECMO support. Survival off ECMO, survival to discharge, and complication rates were similar between the cohorts. CONCLUSIONS A lower Hct threshold of 35% is associated with a reduction in RBC transfusion volume and does not appear to alter complication rates or patient outcomes for neonates receiving ECMO support for respiratory failure.

Abstract
Purpose: We describe an approach for anticoagulation and transfusions in veno-venous–extracorporeal membrane oxygenation (VV-ECMO), evaluating factors associated with higher transfusion requirements, and their impact on mortality. Methods: Observational study on consecutive adults supported with VV-ECMO for acute respiratory distress syndrome (ARDS). We targeted an activated partial thromboplastin time of 40 to 50 seconds and a hematocrit of 24% to 30%. Univariate and multiple analyses were done to evaluate factors associated with transfusion requirements and the influence of increasing transfusions on mortality during ECMO. Results: In a cohort of 82 VV-ECMO patients (PRedicting dEath for SEvere ARDS on VV-ECMO [PRESERVE] score: 4, Interquartile range [IQR]: 3-5, Respiratory Extracorporeal Membrane Oxygenation Survival Prediction [RESP] score: 2, IQR: 2-4), 76 (92.7%) patients received at least 1 unit of packed red blood cells (PRBCs) during the intensive care unit stay related to ECMO (median PRBC/d 156 mL, IQR: 93-218; median ECMO duration 14 days, IQR: 8-22). A higher requirement of PRBC transfusions was associated with pre-ECMO hematocrit, and with the following conditions during ECMO: platelet nadir, antithrombin III (ATIII), and stage 3 of acute kidney injury (all P < .05). Sixty-two (75.6%) patients survived ECMO. Pre-ECMO hospital stay, PRBC transfusion, and septic shock were associated with mortality (all P < .05). The adjusted odds ratio for each 100mL/d increase in PRBC transfusion was 1.9 (95% confidence interval [CI]: 1.1-3.2, P = .01); for the development of septic shock it was 15.4 (95% CI: 1.7-136.8, P = .01), and for each day of pre-ECMO stay it was 1.1 (95% CI: 1-1.2, P = .04). Conclusion: Implementation of a comprehensive protocol for anticoagulation and transfusions in VV-ECMO for ARDS resulted in a low PRBC requirement, and an ECMO survival comparable to data in the literature. Lower ATIII emerged as a factor associated with increased need for transfusions. Higher PRBC transfusions were associated with ECMO mortality. Further investigations are needed to better understand the right level of anticoagulation in ECMO, and the factors to take into account in order to manage personalized transfusion practice in this select setting.

Abstract
Red blood cell (RBC) transfusion is a common and lifesaving therapy for anemic neonates and infants, particularly among those born prematurely or undergoing surgery. However, evidence-based indications for when to administer RBCs and adverse effects of RBC transfusion on important outcomes including necrotizing enterocolitis, survival, and long-term neurodevelopmental impairment remain uncertain. In addition, blood-banking practices for preterm and term neonates and infants have been largely developed using studies from older children and adults. Use of and refinements in emerging technologies and advances in biomarker discovery and neonatal-specific RBC transfusion databases may allow clinicians to better define and tailor RBC transfusion needs and practices to individual neonates. Decreasing the need for RBC transfusion and developing neonatal-specific approaches in the preparation of donor RBCs have potential for reducing resource utilization and cost, improving outcomes, and assuring blood safety. Finally, large donor-recipient-linked cohort studies can provide data to better understand the balance of the risks and benefits of RBC transfusion in neonates. These studies may also guide the translation of new research into best practices that can rapidly be integrated into routine care. This review highlights key opportunities in transfusion medicine and neonatology for improving the preparation and transfusion of RBCs into neonates and infants. We focus on timely, currently addressable knowledge gaps that can increase the safety and efficacy of preterm and term neonatal and infant RBC transfusion practices.

Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) can be deployed to support patients with severe cardiorespiratory failure unresponsive to conventional medical interventions. Neonatal trials have demonstrated that ECMO is an effective treatment of severe respiratory failure, with acceptable cognitive and functional outcomes. Technological advances in ECMO have resulted in improved safety and accessibility, contributing to decreased morbidity and improved survival of increasingly complex patients requiring ECMO support. PURPOSE This review aims to describe the innovations in ECMO technology and management in the neonatal population in the last decade. The long-term outcomes of neonatal patients requiring ECMO support will be discussed. SEARCH STRATEGY Relevant clinical trials from MEDLINE and the Cochrane Library were identified. The following key words were used: ECMO, infant, neonate, and outcomes. FINDINGS Challenges still remain in supporting the premature and/or low-birth-weight infant with severe respiratory failure, as well as infants with congenital diaphragmatic hernia. Neonatal ECMO survivors can present with neurodevelopmental and respiratory problems, which become more prominent with time. IMPLICATIONS FOR PRACTICE While newer technologies have led to fewer neonates with respiratory failure progressing to ECMO, it remains an important tool to in those who have failed conventional therapies. Given the presence of neurodevelopmental problems in neonatal ECMO survivors, multidisciplinary follow-up targeting motor performance, exercise capacity, behavior, and subtle learning deficits is warranted. IMPLICATIONS FOR RESEARCH With the overall decreasing use of neonatal ECMO, ECMO centers must find ways to maintain their expertise in the light of lower patient volumes amidst complex patient physiology.
