Seeber P, Trentino KM, Murray K, Lucas M. A further update on mortality and morbidity in patients with very low hemoglobin levels who decline blood transfusion. Transfusion 2024; 64:1198-1206. [PMID: 38716878 DOI: 10.1111/trf.17867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 04/20/2024] [Accepted: 04/23/2024] [Indexed: 07/17/2024]
Abstract
BACKGROUND In the past two decades, researchers have published mortality and morbidity rates in patients with very low hemoglobin levels declining blood transfusion. The clinical knowledge and tools available for the management of patients who decline transfusions have grown since these publications. The aim of our study was to provide a further update on outcomes associated with severe anemia in these patients. STUDY DESIGN AND METHODS A retrospective observational study of patients declining allogeneic blood transfusions with nadir hemoglobin levels ≤8 g/dL treated at The Institute for Blood Management, HELIOS Klinikum Gotha, Germany. Outcomes were in-hospital mortality within 30 days and composite morbidity or mortality, with morbidity events defined as acute myocardial infarction, cardiac failure, wound infection, arrhythmia, and pneumonia. RESULTS Between June 2008 and June 2021, The Institute for Blood Management treated 2841 admissions of which 159 (5.6%) recorded nadir hemoglobin levels ≤8 g/dL. Of these, five (3.1%) patients died in hospital within 30 days, including four (4.8%) patients admitted for surgical procedures and one (1.4%) medical admission. There was a significant increase in the unadjusted proportion of composite morbidity or mortality events with severity of nadir hemoglobin, with each gram decrease in hemoglobin associated with a 1.48 (95% confidence interval = 1.05-2.09; p = .025) times increase. CONCLUSION Our comparatively lower proportion of patients reaching hemoglobin levels ≤8 g/dL and lower mortality rates suggest outcomes in patients with severe anemia is modifiable with the application of current patient blood management and bloodless medicine and surgery strategies.

Abstract
Anemia is a pathological condition in which the hemoglobin and red blood cell mass decrease; it is mainly defined by the concentration of hemoglobin in the blood. The World Health Organization guidelines establish specific values to define anemia in different population groups. Early detection of anemia can also be a valuable indicator of underlying medical conditions. Clinical studies have explored the relationship between perioperative anemia and morbidity, highlighting the need for more judicious therapeutic strategies, such as the use of Patient Blood Management, which aims to prevent and treat anemia in a personalized and effective way. Patient Blood Management emerges as a promising approach to dealing with anemia, recognizing that its correction through transfusion always carries risks and that personalized prevention and treatment can offer better outcomes for patients.

Abstract
Understanding the physiological concepts of oxygen delivery is essential to discern the mechanisms that influence its increase, reduction or maintenance in the body. This text explores the different mechanisms that help maintain oxygen delivery even in the face of reduced hemoglobin levels. Adequate oxygen delivery ensures tissue and metabolic balance, which is crucial to avoid harmful consequences such as metabolic acidosis and cellular dysoxia. The complex interaction between variables such as cardiac output, hemoglobin and heart rate (HR) plays a fundamental role in maintaining oxygen delivery, allowing the body to temporarily adjust to situations of anemia or high metabolic demand. It is important to emphasize that blood transfusions should not be based on fixed values, but rather on individual metabolic needs. Strategies to reduce myocardial consumption and monitor macro and micro hemodynamics help in making rational decisions. Individualizing treatment and considering factors such as blood viscosity in relation to the benefits of transfusion are increasingly relevant to optimize therapy and minimize risks, especially in complex clinical scenarios, such as neurocritical patients and trauma victims.

Arynov A, Kaidarova D, Kabon B. Alternative blood transfusion triggers: a narrative review. BMC Anesthesiol 2024; 24:71. [PMID: 38395758 PMCID: PMC10885388 DOI: 10.1186/s12871-024-02447-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 02/07/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Anemia, characterized by low hemoglobin levels, is a global public health concern. Anemia is an independent factor worsening outcomes in various patient groups. Blood transfusion has been the traditional treatment for anemia; its triggers, primarily based on hemoglobin levels; however, hemoglobin level is not always an ideal trigger for blood transfusion. Additionally, blood transfusion worsens clinical outcomes in certain patient groups. This narrative review explores alternative triggers for red blood cell transfusion and their physiological basis. MAIN TEXT The review delves into the physiology of oxygen transport and highlights the limitations of using hemoglobin levels alone as transfusion trigger. The main aim of blood transfusion is to optimize oxygen delivery, necessitating an individualized approach based on clinical signs of anemia and the balance between oxygen delivery and consumption, reflected by the oxygen extraction rate. The narrative review covers different alternative triggers. It presents insights into their diagnostic value and clinical applications, emphasizing the need for personalized transfusion strategies. CONCLUSION Anemia and blood transfusion are significant factors affecting patient outcomes. While restrictive transfusion strategies are widely recommended, they may not account for the nuances of specific patient populations. The search for alternative transfusion triggers is essential to tailor transfusion therapy effectively, especially in patients with comorbidities or unique clinical profiles. Investigating alternative triggers not only enhances patient care by identifying more precise indicators but also minimizes transfusion-related risks, optimizes blood product utilization, and ensures availability when needed. Personalized transfusion strategies based on alternative triggers hold the potential to improve outcomes in various clinical scenarios, addressing anemia's complex challenges in healthcare. Further research and evidence are needed to refine these alternative triggers and guide their implementation in clinical practice.

Abstract
STUDY DESIGN Retrospective case-control study. OBJECTIVE To explore the association of early postoperative nadir hemoglobin with risk of a composite outcome of anemia-related and other adverse events. METHODS We retrospectively analyzed data from spinal tumor patients who received intraoperative blood transfusion between September 1, 2013 and December 31, 2020. Uni- and multivariate logistic regression was used to explore relationships of clinicodemographic and surgical factors with risk of composite in-hospital adverse events, including death. Subgroup analysis explored the relationship between early postoperative nadir hemoglobin and composite adverse events. RESULTS Among the 345 patients, 331 (95.9%) experienced early postoperative anemia and 69 (20%) experienced postoperative composite adverse events. Multivariate logistic regression analysis showed that postoperative nadir Hb (OR = .818, 95% CI: .672-.995, P = .044), ASA ≥3 (OR = 2.007, 95% CI: 1.086-3.707, P = .026), intraoperative RBC infusion volume (OR = 1.133, 95% CI: 1.009-1.272, P = .035), abnormal hypertension (OR = 2.199, 95% CI: 1.085-4.457, P = .029) were correlated with composite adverse events. The lumbar spinal tumor was associated with composite adverse events with a decreased odds compared to thoracic spinal tumors (OR = .444, 95% CI: .226-.876, P = .019). Compared to patients with postoperative nadir hemoglobin ≥11.0 g/dL, those with nadir <9.0 g/dL were at significantly higher risk of postoperative composite adverse events (OR = 2.709, 95% CI: 1.087-6.754, P = .032). CONCLUSION Nadir hemoglobin <9.0 g/dL after spinal tumor surgery is associated with greater risk of postoperative composite adverse events in patients who receive intraoperative blood transfusion.

Abstract
BACKGROUND AND OBJECTIVES Japan's ageing society has increased the need for home healthcare, including home transfusions. We hence aimed to elucidate the purpose and utilization of home transfusions in Japan, which has not been clarified to date. MATERIALS AND METHODS Clinics throughout Japan that provide home care and have experience in performing blood transfusions were surveyed. The study period was February to December 2019, and information of patients receiving home red blood cell transfusions, including patient background, pre-transfusion laboratory data and the purpose of the transfusions, was collected. RESULTS Haematological malignancies and solid tumours accounted for 70% of the patients' underlying diseases, with the former being significantly more common in urban areas. Regarding the purpose of the home transfusions, haematologists focused on symptom improvement, whereas gastroenterology surgeons focused on life support. Furthermore, maintenance of life was more likely to be the aim in the group of patients with the lowest level of activities of daily living. The main items that were significantly associated with a low haemoglobin level before transfusion included age ≥90 years and a gastroenterologist being the physician in charge. CONCLUSION Home transfusions were found to be performed in a restrictive and diverse manner in Japan. Life support is the second most common purpose of home transfusion in Japan, and optimizing effective home transfusion remains a challenge.

Importance of assessing biomarkers and physiological parameters of anemia-induced tissue hypoxia in the perioperative period. BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2023; 73:186-197. [PMID: 36377057 PMCID: PMC10068554 DOI: 10.1016/j.bjane.2022.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 10/14/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022]
Abstract
Anemia is associated with increased risk of Acute Kidney Injury (AKI), stroke and mortality in perioperative patients. We sought to understand the mechanism(s) by assessing the integrative physiological responses to anemia (kidney, brain), the degrees of anemia-induced tissue hypoxia, and associated biomarkers and physiological parameters. Experimental measurements demonstrate a linear relationship between blood Oxygen Content (CaO2) and renal microvascular PO2 (y = 0.30x + 6.9, r2 = 0.75), demonstrating that renal hypoxia is proportional to the degree of anemia. This defines the kidney as a potential oxygen sensor during anemia. Further evidence of renal oxygen sensing is demonstrated by proportional increase in serum Erythropoietin (EPO) during anemia (y = 93.806*10-0.02, r2 = 0.82). This data implicates systemic EPO levels as a biomarker of anemia-induced renal tissue hypoxia. By contrast, cerebral Oxygen Delivery (DO2) is defended by a profound proportional increase in Cerebral Blood Flow (CBF), minimizing tissue hypoxia in the brain, until more severe levels of anemia occur. We hypothesize that the kidney experiences profound early anemia-induced tissue hypoxia which contributes to adaptive mechanisms to preserve cerebral perfusion. At severe levels of anemia, renal hypoxia intensifies, and cerebral hypoxia occurs, possibly contributing to the mechanism(s) of AKI and stroke when adaptive mechanisms to preserve organ perfusion are overwhelmed. Clinical methods to detect renal tissue hypoxia (an early warning signal) and cerebral hypoxia (a later consequence of severe anemia) may inform clinical practice and support the assessment of clinical biomarkers (i.e., EPO) and physiological parameters (i.e., urinary PO2) of anemia-induced tissue hypoxia. This information may direct targeted treatment strategies to prevent adverse outcomes associated with anemia.

Abstract
Patient blood management (PBM) is a systematic, evidence-based approach to improve patient outcomes by managing and preserving a patient's own blood and minimizing allogenic transfusion need and risk. According to the PBM approach, the goals of perioperative anemia management include early diagnosis, targeted treatment, blood conservation, restrictive transfusion except in cases of acute and massive hemorrhage, and ongoing quality assurance and research efforts to advance overall blood health.

Abstract
Cardiac surgery in Jehovah's Witnesses (JW) patients who refuse blood transfusion is challenging requiring dedicated strategies. We aimed to analyze non-selected JW patients undergoing cardiac surgery and to compare with matched controls both perioperative outcomes and long-term survival. We retrospectively analyzed JW patients undergoing cardiac surgery from January 2016 to March 2021 and compared them with matched controls. The primary outcome was a composite of in-hospital perioperative adverse events and in-hospital mortality. The secondary outcome was all-cause mortality at long-term follow-up. A total of 113 JW patients and 113 controls were included. Baseline clinical characteristics, including laboratory parameters were comparable. Overall, there were no statistical differences between JW vs controls in terms of in-hospital mortality (2.7% vs 1.8%, p = 1.00) but mortality was remarkably high (40%) in JW patients with post-op hemoglobin < 8 g/dl. Logistic regression analysis found that the JW group was not associated with a higher occurrence of the composite outcome (adjusted odds ratio 0.91, 95% confidence interval [CI] 0.54-1.57). After a median follow-up of 1397 [IQR 922.7-1723.5] days, JW patients were not associated with a significantly higher all-cause mortality (adjusted hazard ratio 0.77, 95% CI 0.24-2.42). Cardiac surgery can be safely performed in non-anemic JW patients despite the refusal of blood transfusions. Favorable clinical outcomes can be achieved by the use of specific perioperative strategies for bloodless surgery with no differences as compared to control patients except in JW patients with a very low level of post-operative hemoglobin not supported by immediate transfusions.

Stawschenko E, Schaller T, Kern B, Bode B, Dörries F, Kusche-Vihrog K, Gehring H, Wegerich P. Current Status of Measurement Accuracy for Total Hemoglobin Concentration in the Clinical Context. BIOSENSORS 2022; 12:1147. [PMID: 36551114 PMCID: PMC9775510 DOI: 10.3390/bios12121147] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Revised: 11/22/2022] [Accepted: 12/01/2022] [Indexed: 06/17/2023]
Abstract
OBJECTIVE The main objective of this investigation is to provide data about the accuracy of total hemoglobin concentration measurements with respect to clinical settings, and to devices within the categories of point-of-care and reference systems. In particular, tolerance of hemoglobin concentrations below 9 g/dL that have become common in clinical practice today determines the need to demonstrate the limits of measurement accuracy in patient care. METHODS Samples extracted from six units of heparinized human blood with total hemoglobin concentrations ranging from 3 to 18 g/dL were assigned to the test devices in a random order. The pool of test devices comprised blood gas analyzers, an automatic hematology analyzer, a laboratory reference method, and the point-of-care system HemoCue. To reduce the pre-analytic error, each sample was measured three times. Due to the characteristics of the tested devices and methods, we selected the mean values of the data from all these devices, measured at the corresponding total hemoglobin concentrations, as the reference. MAIN RESULTS The measurement results of the test devices overlap within strict limits (R2 = 0.999). Only the detailed analysis provides information about minor but systematic deviations. In the group of clinically relevant devices, which are involved in patient blood management decisions, the relative differences were within the limit of +/- 5 % for values down to 3 g/dL. CONCLUSIONS A clinically relevant change of +/- 0.5 g/dL of total hemoglobin concentration can be detected with all selected devices and methods. Compliance with more stringent definitions-these are the relative differences of 5 % in relation to the corresponding reference values and the clinically adapted thresholds in the format of a tolerance level analysis-was achieved by the clinical devices assessed here.

Recovery of organ-specific tissue oxygen delivery at restrictive transfusion thresholds after fluid treatment in ovine haemorrhagic shock. Intensive Care Med Exp 2022; 10:12.

Abstract
Background Fluid resuscitation is the standard treatment to restore circulating blood volume and pressure after massive haemorrhage and shock. Packed red blood cells (PRBC) are transfused to restore haemoglobin levels. Restoration of microcirculatory flow and tissue oxygen delivery is critical for organ and patient survival, but these parameters are infrequently measured. Patient Blood Management is a multidisciplinary approach to manage and conserve a patient’s own blood, directing treatment options based on broad clinical assessment beyond haemoglobin alone, for which tissue perfusion and oxygenation could be useful. Our aim was to assess utility of non-invasive tissue-specific measures to compare PRBC transfusion with novel crystalloid treatments for haemorrhagic shock. Methods A model of severe haemorrhagic shock was developed in an intensive care setting, with controlled haemorrhage in sheep according to pressure (mean arterial pressure 30–40 mmHg) and oxygen debt (lactate > 4 mM) targets. We compared PRBC transfusion to fluid resuscitation with either PlasmaLyte or a novel crystalloid. Efficacy was assessed according to recovery of haemodynamic parameters and non-invasive measures of sublingual microcirculatory flow, regional tissue oxygen saturation, repayment of oxygen debt (arterial lactate), and a panel of inflammatory and organ function markers. Invasive measurements of tissue perfusion, oxygen tension and lactate levels were performed in brain, kidney, liver, and skeletal muscle. Outcomes were assessed during 4 h treatment and post-mortem, and analysed by one- and two-way ANOVA. Results Each treatment restored haemodynamic and tissue oxygen delivery parameters equivalently (p > 0.05), despite haemodilution after crystalloid infusion to haemoglobin concentrations below 70 g/L (p < 0.001). Recovery of vital organ-specific perfusion and oxygen tension commenced shortly before non-invasive measures improved. Lactate declined in all tissues and correlated with arterial lactate levels (p < 0.0001). The novel crystalloid supported rapid peripheral vasodilation (p = 0.014) and tended to achieve tissue oxygen delivery targets earlier. PRBC supported earlier renal oxygen delivery (p = 0.012) but delayed peripheral perfusion (p = 0.034). Conclusions Crystalloids supported vital organ oxygen delivery after massive haemorrhage, despite haemodilution to < 70 g/L, confirming that restrictive transfusion thresholds are appropriate to support oxygen delivery. Non-invasive tissue perfusion and oximetry technologies merit further clinical appraisal to guide treatment for massive haemorrhage in the context of Patient Blood Management.

Abstract
Uncontrolled and massive bleeding with derangement of coagulation is a major challenge in the management of both surgical and seriously injured patients. The underlying mechanism of trauma-induced or -associated coagulopathy is tissue injury in the presence of shock and acidosis provoking endothelial damage, activation of inflammation, and coagulation disbalancing. Furthermore, the combination of ongoing blood loss and consumption of blood components that are essential for effective coagulation worsens uncontrolled hemorrhage. Additionally, therapeutic actions, such as resuscitation with replacement fluids or allogeneic blood products, can further aggravate coagulopathy. Of the coagulation factors essential to the clotting process, fibrinogen is the first to be consumed to critical levels during acute bleeding and current evidence suggests that normalizing fibrinogen levels in bleeding patients improves clot formation and clot strength, thereby controlling hemorrhage. Three different therapeutic approaches are discussed controversially. Whole blood transfusion is used especially in the military scenario and is also becoming more and more popular in the civilian world, although it is accompanied by a strong lack of evidence and severe safety issues. Transfusion of allogeneic blood concentrates in fixed ratios without any targets has been investigated extensively with disappointing results. Individualized and target-controlled coagulation management based on point-of-care diagnostics with respect to the huge heterogeneity of massive bleeding situations is an alternative and advanced approach to managing coagulopathy associated with massive bleeding in the trauma as well as the perioperative setting.

Abstract
BACKGROUND The optimal haemoglobin threshold for use of red blood cell (RBC) transfusions in anaemic patients remains an active field of research. Blood is a scarce resource, and in some countries, transfusions are less safe than in others because of inadequate testing for viral pathogens. If a liberal transfusion policy does not improve clinical outcomes, or if it is equivalent, then adopting a more restrictive approach could be recognised as the standard of care. OBJECTIVES: The aim of this review update was to compare 30-day mortality and other clinical outcomes for participants randomised to restrictive versus liberal red blood cell (RBC) transfusion thresholds (triggers) for all clinical conditions. The restrictive transfusion threshold uses a lower haemoglobin concentration as a threshold for transfusion (most commonly, 7.0 g/dL to 8.0 g/dL), and the liberal transfusion threshold uses a higher haemoglobin concentration as a threshold for transfusion (most commonly, 9.0 g/dL to 10.0 g/dL). SEARCH METHODS We identified trials through updated searches: CENTRAL (2020, Issue 11), MEDLINE (1946 to November 2020), Embase (1974 to November 2020), Transfusion Evidence Library (1950 to November 2020), Web of Science Conference Proceedings Citation Index (1990 to November 2020), and trial registries (November 2020). We checked the reference lists of other published reviews and relevant papers to identify additional trials. We were aware of one trial identified in earlier searching that was in the process of being published (in February 2021), and we were able to include it before this review was finalised. SELECTION CRITERIA We included randomised trials of surgical or medical participants that recruited adults or children, or both. We excluded studies that focused on neonates. Eligible trials assigned intervention groups on the basis of different transfusion schedules or thresholds or 'triggers'. These thresholds would be defined by a haemoglobin (Hb) or haematocrit (Hct) concentration below which an RBC transfusion would be administered; the haemoglobin concentration remains the most commonly applied marker of the need for RBC transfusion in clinical practice. We included trials in which investigators had allocated participants to higher thresholds or more liberal transfusion strategies compared to more restrictive ones, which might include no transfusion. As in previous versions of this review, we did not exclude unregistered trials published after 2010 (as per the policy of the Cochrane Injuries Group, 2015), however, we did conduct analyses to consider the differential impact of results of trials for which prospective registration could not be confirmed. DATA COLLECTION AND ANALYSIS: We identified trials for inclusion and extracted data using Cochrane methods. We pooled risk ratios of clinical outcomes across trials using a random-effects model. Two review authors independently extracted data and assessed risk of bias. We conducted predefined analyses by clinical subgroups. We defined participants randomly allocated to the lower transfusion threshold as being in the 'restrictive transfusion' group and those randomly allocated to the higher transfusion threshold as being in the 'liberal transfusion' group. MAIN RESULTS A total of 48 trials, involving data from 21,433 participants (at baseline), across a range of clinical contexts (e.g. orthopaedic, cardiac, or vascular surgery; critical care; acute blood loss (including gastrointestinal bleeding); acute coronary syndrome; cancer; leukaemia; haematological malignancies), met the eligibility criteria. The haemoglobin concentration used to define the restrictive transfusion group in most trials (36) was between 7.0 g/dL and 8.0 g/dL. Most trials included only adults; three trials focused on children. The included studies were generally at low risk of bias for key domains including allocation concealment and incomplete outcome data. Restrictive transfusion strategies reduced the risk of receiving at least one RBC transfusion by 41% across a broad range of clinical contexts (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.53 to 0.66; 42 studies, 20,057 participants; high-quality evidence), with a large amount of heterogeneity between trials (I² = 96%). Overall, restrictive transfusion strategies did not increase or decrease the risk of 30-day mortality compared with liberal transfusion strategies (RR 0.99, 95% CI 0.86 to 1.15; 31 studies, 16,729 participants; I² = 30%; moderate-quality evidence) or any of the other outcomes assessed (i.e. cardiac events (low-quality evidence), myocardial infarction, stroke, thromboembolism (all high-quality evidence)). High-quality evidence shows that the liberal transfusion threshold did not affect the risk of infection (pneumonia, wound infection, or bacteraemia). Transfusion-specific reactions are uncommon and were inconsistently reported within trials. We noted less certainty in the strength of evidence to support the safety of restrictive transfusion thresholds for the following predefined clinical subgroups: myocardial infarction, vascular surgery, haematological malignancies, and chronic bone-marrow disorders. AUTHORS' CONCLUSIONS Transfusion at a restrictive haemoglobin concentration decreased the proportion of people exposed to RBC transfusion by 41% across a broad range of clinical contexts. Across all trials, no evidence suggests that a restrictive transfusion strategy impacted 30-day mortality, mortality at other time points, or morbidity (i.e. cardiac events, myocardial infarction, stroke, pneumonia, thromboembolism, infection) compared with a liberal transfusion strategy. Despite including 17 more randomised trials (and 8846 participants), data remain insufficient to inform the safety of transfusion policies in important and selected clinical contexts, such as myocardial infarction, chronic cardiovascular disease, neurological injury or traumatic brain injury, stroke, thrombocytopenia, and cancer or haematological malignancies, including chronic bone marrow failure. Further work is needed to improve our understanding of outcomes other than mortality. Most trials compared only two separate thresholds for haemoglobin concentration, which may not identify the actual optimal threshold for transfusion in a particular patient. Haemoglobin concentration may not be the most informative marker of the need for transfusion in individual patients with different degrees of physiological adaptation to anaemia. Notwithstanding these issues, overall findings provide good evidence that transfusions with allogeneic RBCs can be avoided in most patients with haemoglobin thresholds between the range of 7.0 g/dL and 8.0 g/dL. Some patient subgroups might benefit from RBCs to maintain higher haemoglobin concentrations; research efforts should focus on these clinical contexts.

Abstract
Complex surgery associated with major hemorrhage presents particular risks for Jehovah's Witnesses who do not accept transfusion of blood products. Intraoperative use of two cell saver machines simultaneously can maximize the yield of salvaged blood from both the operative field and from washed surgical swabs and can potentially be life-saving.

Abstract
ABSTRACT Before death, patients commonly experience impaired consciousness for a significant period, frequently preventing family and others from final interactions with the patient. Some of these episodes of cognitive impairment may be treatable, with treatment not offered owing to the perception of ultimate futility or expense, or both. One of the causes of terminal loss of consciousness or decreased lucidity can be inadequate cerebral oxygen delivery. We report five cases from four institutions where an infusion of a hemoglobin-based oxygen carrier to patients who were unconscious or not lucid owing to acute severe anemia (hemoglobin range, 2.1-5.2 g/dL) resulted in awakening or lucidity. We review briefly human cognitive function and anemia and remark about the use of a hemoglobin-based oxygen carrier for acute severe anemia when red cell transfusion is not an option.

Abstract
Severe anemia in Jehovah's Witness patients has long been a complex and sometimes divisive issue, especially in children and adolescents. In adolescent patients old enough to express their wishes, the decision to transfuse becomes more complicated. We present the case of a 12-year-old Jehovah's Witness female with severe anemia (hemoglobin of 2.6 g/dL) secondary to menorrhagia. She was successfully managed without transfusion, for which the patient and her family were deeply grateful. This case demonstrates that it is possible to manage severe iron deficiency anemia without transfusion.

Abstract
BACKGROUND Blood transfusions though life-saving are not entirely benign. They are the most overused procedure in the hospital and have been under scrutiny by the 'Choosing Wisely campaign'. The strict adoption of restrictive transfusion guidelines could improve patient outcomes while reducing cost. OBJECTIVES In this study, we evaluate adherence to restrictive transfusion guidelines, along with hospital mortality and length of stay (LOS) in transfusion events with a pre-transfusion haemoglobin (Hb) ≥7 g/dl. Additionally, we evaluated associated costs accrued due to unnecessary transfusions. METHODS We conducted a retrospective observational study in a 64-bed medical intensive care unit (MICU) of an academic medical centre involving all adult patients (N = 957) requiring packed red blood cell transfusion between January 2015 and December 2015. RESULTS In total, 3140 units were transfused with a mean pre-transfusion Hb of 6.75 ± 0.86 g/dl. Nine hundred forty-four (30%) transfusion events occurred with a pre-transfusion Hb ≥7 g/dl, and 385 (12.3%) of these occurred in patients without hypotension, tachycardia, use of vasopressors, or coronary artery disease. Forgoing them could have led to a savings of approximately 0.3 million dollars. Transfusion events with pre-transfusion Hb ≥7 g/dl were associated with an increased mortality in patients with acute blood loss (odds ratio [OR] 2.08, 95% confidence interval [CI] 1.11-3.88; p = 0.02) and LOS in patients with chronic blood loss (β1 .8.26, 95% CI 4.09-12.43; p < 0.01). CONCLUSION A subset of anaemic patients in the MICU still receive red blood cell transfusions against restrictive guidelines offering hospitals the potential for effective intervention that has both economic and clinical implications.

Zhou L, Liu X, Yan M, Zhao W, Luo D, Liu J, Chen C, Ming Y, Zhang F, Li Q, Du L, Liu J. Postoperative Nadir Hemoglobin and Adverse Outcomes in Patients Undergoing On-Pump Cardiac Operation. Ann Thorac Surg 2021; 112:708-716. [PMID: 33484676 DOI: 10.1016/j.athoracsur.2021.01.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 12/23/2020] [Accepted: 01/12/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND Patients undergoing cardiac operation are susceptible to anemia. Low hemoglobin concentration is a risk factor for composite adverse events and death after cardiac operation. Here we investigated the association of postoperative nadir hemoglobin with adverse outcomes in patients undergoing on-pump cardiac operation. METHODS Adult patients in 2 medical centers were retrospectively analyzed. The primary outcome was postoperative composite adverse events. The secondary outcome was all-cause death in the hospital. RESULTS Of the 8206 patients analyzed, 1628 (19.8%) experienced composite adverse events after operation and 109 (1.3%) died. Patients receiving on-pump cardiac operation with nadir hemoglobin of 9.0 to 9.9 g/L showed a low incidence of composite adverse events (175 of 1423 [12.3%]) and death (5 of 1423 [0.4%]). Compared with nadir hemoglobin at 9.0 to 9.9 g/dL, the relative risk (RR) of composite adverse events increased stepwise as nadir hemoglobin fell below 9.0 g/dL: adjusted RR was 1.44 (95% confidence interval [CI], 1.14-1.83) for 8.5 to 8.9 g/dL, 1.56 (95% CI, 1.23-1.99) for 8.0 to 8.4 g/dL, 1.66 (95% CI, 1.31-2.11) for 7.5 to 7.9 g/dL, 2.22 (95% CI, 1.75-2.83) for 7.0 to 7.4 g/dL, and 4.00 (95% CI, 3.18-5.04) for less than 7 .0 g/dL. Furthermore, the risk of death was significantly higher when nadir hemoglobin was below 7.0 g/dL than when it was 9.0 to 9.9 g/dL (RR, 5.36; 95% CI, 2.20-16.12). CONCLUSIONS Compared with the risks when nadir hemoglobin is 9.0 to 9.9 g/dL, the risk of composite adverse events increases when postoperative nadir hemoglobin is below 9.0 g/dL, whereas risk of death increases when nadir hemoglobin is below 7.0 g/dL.

Quantification and influencing factors of perioperative hidden blood loss during intramedullary fixation for intertrochanteric fractures in the elderly. Arch Orthop Trauma Surg 2020; 140:1339-1348.

Abstract
INTRODUCTION We aimed to quantify perioperative hidden blood loss (HBL) and investigate its influencing factors in elderly patients with intertrochanteric fractures (IFs) undergoing intramedullary fixation surgery. MATERIALS AND METHODS We prospectively collected the clinical data of 200 elderly patients with IFs treated with intramedullary fixation surgery in our hospital between December 1, 2014 and August 31, 2018. The intraoperative visible blood loss, blood transfusion rate, and pre- and postoperative hemoglobin (Hb) levels as well as the general characteristics of the enrolled patients were recorded. A multiple linear regression analysis model (stepwise) was used to identify independent factors affecting perioperative HBL. RESULTS The mean perioperative HBL was 614.72 ± 368.14 mL, which accounted for 84.05% of the mean total perioperative blood loss (731.37 ± 391.50 mL). The mean preoperative HBL was 368.33 ± 325.57 mL, which accounted for 50.36% of the mean total perioperative blood loss. Patients with fracture types AO/OTA 31-A2.2 to A3.3 had more severe preoperative HBL (median 580.10 mL), and most of them developed mild-to-moderate anemia before the operation, and 27.63% of them received preoperative blood transfusion. Compared with patients operated within 5 days after injury, patients operated over 5 days had lower Hb value at admission (101.56 ± 19.49 vs. 107.28 ± 16.53; P = 0.026) and higher preoperative transfusion rate (25.84% vs. 9.01%; P = 0.001). Multiple linear regression analysis revealed that fracture types AO/OTA 31-A2.2 to A3.3, male sex, right-sided injury, and operation time > 60 min were independently associated with increased perioperative HBL. Tranexamic acid treatment was negatively correlated with perioperative HBL. CONCLUSION IFs in elderly patients undergoing intramedullary fixation surgery were associated with significant perioperative HBL and anemia. Persistent HBL occurred before the operation and on the first few postoperative days. Surgeons should pay more attention to preoperative HBL in patients with fracture types AO/OTA 31-A2.2 to A3.3 and regularly measure Hb levels preoperatively to avoid anemia. Shortening preoperative time may helps to reduce preoperative blood loss.

Abstract
PURPOSE To evaluate the outcomes of emergency endovascular treatments for delayed bleeding after pancreaticobiliary surgery. METHODS We retrospectively evaluated 21 patients (M:F = 13:8, median age = 64 years) undergoing 23 endovascular treatments, performed from 2010 to 2017 in a single center. Data collected were patient characteristics; surgery; pathology; incidence of postoperative pancreatic fistulas (POPF); bleeding signs on CT and angiography; damaged artery; endovascular tools used; technical and clinical success; intervals between surgery, endovascular treatment, and discharge; survival rates. RESULTS Sixteen patients had pancreatoduodenectomy, three hepaticojejunostomy, two distal pancreatectomy. Indications for surgery were mainly biliary (33%), pancreatic (19%), or duodenal (10%) malignancies. Seventeen patients had "grade C" POPF, three suffered a biliary leak, one had no POPF. Active bleeding was present in 17/23 CTs and in 22/23 angiographies, mostly from hepatic (43%), gastroduodenal (22%), and splenic (13%) arteries. The endovascular treatments were performed with coils (26%), glue (22%), stent-graft (22%), and their combinations (30%). Sixteen patients had a single endovascular treatment, one underwent a second embolization, three had subsequent surgery, one had repeat embolization followed by surgery. Relaparotomy rate was 19%. Median hospital stay was 37 days (range 12-75); median intervals among pancreaticobiliary surgery, endovascular treatment, and discharge were 21 (2-36) and 12 (8-47) days, respectively. We observed 4/21 intrahospital deaths (median: 31 days from endovascular treatment, 4-53); 1-year survival rate of discharged patients was 71%. CONCLUSIONS Endovascular treatment using embolization and/or stent-graft placement is a useful first-line intervention to halt postoperative hemorrhage after pancreaticobiliary surgery and decreases the need for urgent relaparotomy.

Abstract
Alternatives to blood for use in transfusion medicine have been investigated for decades. An ideal alternative should improve oxygen (O2)-carrying capacity and O2 delivery and support microvascular blood flow. Previous studies have shown that large-molecular diameter hemoglobin (Hb)-based oxygen carriers (HBOCs) based on polymerized bovine Hb (PolybHb) reduce the toxicity and vasoconstriction of first-generation HBOCs by increasing blood and plasma viscosity and preserving microvascular perfusion. The objective of this study was to examine the impact of PolybHb concentration and therefore O2-carrying capacity and solution viscosity on resuscitation from hemorrhagic shock in rats. PolybHb was diafiltered on a 500-kDa tangential flow filtration (TFF) module to remove low-molecular weight (MW) PolybHb molecules from the final product. Rats were hemorrhaged and maintained in hypovolemic shock for 30 min before transfusion of PolybHb at 10 g/dL (PHB10), 5 g/dL (PHB5), or 2.5 g/dL (PHB2.5) concentration, to restore blood pressure to 90% of the animal's baseline blood pressure. Resuscitation restored blood pressure and cardiac function in a PolybHb concentration-dependent manner. Parameters indicative of the heart's metabolic activity indicated that the two higher PolybHb concentrations better restored coronary O2 delivery compared with the low concentration evaluated. Markers of organ damage and inflammation were highest for PHB10, whereas PHB5 and PHB2.5 showed similar expression of these markers. These studies indicate that a concentration of ~5 g/dL of PolybHb may be near the optimal concentration to restore cardiac function, preserve organ function, and mitigate the toxicity of PolybHb during resuscitation from hemorrhagic shock.NEW & NOTEWORTHY Large-molecular diameter polymerized bovine hemoglobin avoided vasoconstriction and impairment of cardiac function during resuscitation from hemorrhagic shock that was seen with previous hemoglobin-based O2 carriers by increasing blood viscosity in a concentration-dependent manner. Supplementation of O2-carrying capacity played a smaller role in maintaining cardiac function than increased blood and plasma viscosity.

Sublingual microcirculation does not reflect red blood cell transfusion thresholds in the intensive care unit-a prospective observational study in the intensive care unit. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2020; 24:18.

Abstract
Purpose Hemoglobin (Hb) transfusion thresholds are established in intensive care units. A restrictive transfusion threshold (Hb 70–75 g/l) is recommended in septic patients, and a liberal transfusion threshold (Hb 90 g/l) for cardiogenic shock. It is unclear whether these historically adopted transfusion thresholds meet the challenges of individual patients. Methods We evaluated microvascular flow index (MFI) and proportion of perfused vessels (PPV) in the sublingual microcirculation with CytoCam-IDF microscopy and near-infrared spectroscopy (NIRS). A study team-independent, treating intensivist assigned a total of 64 patients to 1 of 2 two transfusion thresholds, 43 patients to the Hb 75 g/l threshold and 21 patients to the Hb 90 g/l threshold, at a surgical intensive care unit. We performed microcirculatory measurements 1 h before and 1 h after transfusion of 1 unit of red blood cells. Results Microcirculatory flow variables correlated negatively with pre-transfusion flow variables (ΔMFI: ρ = − 0.821, p < 0.001; ΔPPV: ρ = − 0.778, p < 0.001). Patients with good initial microcirculation (cutoffs: MFI > 2.84, PPV > 88%) showed a deteriorated microcirculation after red blood cell transfusion. An impaired microcirculation improved after transfusion. At both transfusion thresholds, approximately one third of the patients showed an initially impaired microcirculation. In contrast, one third in every group had good microcirculation above the cutoff variables and did not profit from the transfusion. Conclusion The data suggest that the established transfusion thresholds and other hemodynamic variables do not reflect microcirculatory perfusion of patients. Blood transfusion at both thresholds 75 g/l and 90 g/l hemoglobin can either improve or harm the microcirculatory blood flow, questioning the concept of arbitrary transfusion thresholds.

Abstract
Vigilance is essential in the perioperative period. When blood is not an option for the patient, especially in a procedure/surgery that normally holds a risk for blood transfusion, complexity is added to the management. Current technology and knowledge has made avoidance of blood transfusion a realistic option but it does require a concerted patient-centered effort from the perioperative team. In this article, we provide suggestions for a successful, safe, and bloodless journey for patients. The approaches include preoperative optimization as well as intraoperative and postoperative techniques to reduce blood loss, and also introduces current innovative substitutes for transfusions. This article also assists in considering and maneuvering through the legal and ethical systems to respect patients' beliefs and ensuring their safety.

Abstract
BACKGROUND Jehovah's Witness (JW) patients strictly refuse allogeneic blood transfusion for religious reasons. Nevertheless, JW also wish to benefit from modern therapeutic concepts including major surgical procedures without facing an excessive risk of death. The Northwest Hospital in Frankfurt am Main Germany is a confidential clinic of JW and performs approximately 100 surgical interventions per year on this patient group. MATERIAL AND METHODS A retrospective analysis of closed medical cases performed in the years 2008-2018 at the Northwest Hospital aimed to clarify (1) the frequency of surgical procedures in JW patients associated with a statistical allogeneic transfusion risk (presence of preoperative anemia and/or in-house transfusion probability >10%) during this time period, (2) the degree of acceptance of strategies avoiding blood transfusion by JW and (3) the anemia-related postoperative mortality rate in JW patients. RESULTS In the 11- year observation period 123 surgical procedures with a relevant allogeneic transfusion risk were performed in 105 JW patients. Anemia according to World Health Organization (WHO) criteria was present in 44% of cases on the day of surgery. Synthetic and recombinant drugs (tranexamic acid, desmopressin, erythropoetin, rFVIIa) were generally accepted, acute normovolemic hemodilution (ANH) in 92% and cell salvage in 96%. Coagulation factor concentrates extracted from human plasma and therefore generally refused by JW so far, were accepted by 83% of patients following detailed elucidation. Out of 105 JW patients 7 (6.6%) died during the postoperative hospital stay. In 4 of the 7 fatal cases the cause of death could be traced back to severe postoperative anemia. CONCLUSION Given optimal management JW patients can undergo major surgery without an excessive risk of death. The 6.6% in-hospital mortality observed in this institution was in the range of the 4% generally observed after surgery in Europe. The majority of JW patients accepted a variety of blood conservation strategies following appropriate elucidation. This also included coagulation factor concentrates extracted from human plasma enabling an effective treatment of even severe bleeding complications. In this analysis postoperative hemoglobin concentrations below 6 g/dl in older JW patients were associated with a high mortality risk due to anemia.

Abstract
BACKGROUND While closed suction drains (CSDs) are still frequently employed in clinical practice, the supporting evidence is limited with some studies demonstrating a failure of routine CSD use in preventing hematoma or seroma. Nonetheless, CSD quantity and quality fluid assessment is still appreciated by clinicians to detect postoperative bleeding. This study investigates the value of routine CSD use, in breast surgery, to predict postoperative bleeding. METHODS A retrospective, intra-individual analysis, of CSD fluid volumes between the hematoma side and the unaffected contralateral breast, was undertaken in patients (n = 20) with unilateral postoperative bleeding following bilateral breast surgery (2003-2018). Statistical analysis was undertaken to establish a minimum cutoff fluid volume that might assist in the detection of postoperative bleeding. To determine the usefulness of quality assessment of CSD fluid output by visual inspection, surgeons (n = 56) prospectively matched six eligible hemoglobin concentrations corresponding to pre-filled CSDs. RESULTS Statistical analysis did not yield a clinically reliable cutoff fluid volume indicating postoperative bleeding. All six eligible hemoglobin concentrations were completely successfully matched to pre-filled CSDs by 30.4% (17/56) of surgeons. CONCLUSIONS This study questions the significance of routine CSD use to assist in the decision-making process to return to the theater and address postoperative bleeding. Quantity as well as quality analysis of CSD fluid output failed the reliability and diagnostic validity tests.

Abstract
PURPOSE OF REVIEW This review highlights the complexity of caring for gynecologic patients who refuse blood transfusion and discusses the importance of early, targeted perioperative and intraoperative medical optimization. We review alternative interventions and the importance of medical management to minimize blood loss and maximize hematopoiesis, particularly in gynecologic patients who may have significant uterine bleeding. The review also focuses on intraoperative interventions and surgical techniques to prevent and control surgical blood loss. RECENT FINDINGS With improvements in surgical technique, greater availability of minimally invasive surgery, and increased use of preop UAE and cell salvage, definitive surgical management can be safely performed. New technologies have been developed that allow for safer surgeries or alternatives to traditional surgical procedures. Many medical therapies have been shown to decrease blood loss and improve surgical outcomes. Nonsurgical interventions have also been developed for use as adjuncts or alternatives to surgery. SUMMARY The care of a patient who declines blood transfusion may be complex, but gynecologic surgeons can safely and successfully offer a wide variety of therapies depending on the patient's goals and needs. Medical management should be implemented early. A multidisciplinary team should be mobilized to provide comprehensive and patient-centered care.

Abstract
Incidence of wound complications after kidney transplantation (KTx) is still considerable. Here, we report the impact of prophylactic absorbable polyglactin (Vicryl®) mesh reinforcement on the incidence of short-term post-KTx wound complications. Sixty-nine patients were analyzed; 23 with and 46 without preventive onlay mesh reinforcement. Surgical site infections (SSI) were seen in six (26%) patients in the mesh group and in 17 (37%) patients in no-mesh group. A lower, but not statistically significant, rate of early postoperative wound complications occurred in the mesh group. Wound complications were observed in seven (30%) patients in the mesh group and in 23 (50%) patients in the no-mesh group. There was no association between mesh placement and SSI incidence (odds ratios [OR] 0.60, 95% confidence interval [CI] 0.20-1.82, p = 0.369) and wound complications (OR 0.44, 95% CI 0.15-1.26, p = 0.126). Therefore, we conclude that mesh reinforcement does not increase the risk of SSI and overall wound complications. Long-term outcomes have to be evaluated in a randomized trial setting. © 2019 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater 108B:67-72, 2020.

Abstract
Jehovah’s Witnesses (JW) represent a complex patient population due to their refusal to accept blood transfusions on religious grounds. Pharmacologic management of anemic JW patients is limited to stimulation of hematopoiesis by iron and erythropoietin supplementation and reduction of blood loss by prothrombin complex concentrates (PCCs). Hemoglobin-based oxygen carriers (HBOCs) represent the only pharmacologic modality for JW patients capable of acutely increasing a patient’s oxygen carrying capacity in the setting of organ failure, yet clinical safety and efficacy data are lacking in this population. We report 3 cases in which the HBOC, PEGylated carboxyhemoglobin bovine (Sanguinate®), was requested under emergent circumstances for severely anemic (hemoglobin <5 g/dL) JW patients who refused blood transfusions. Two patients received PEGylated carboxyhemoglobin infusions for severe anemia, while the third patient died prior to receiving the medication. One patient who received Sanguinate died after 5 units of medication. The other patient’s hemoglobin recovered and she was discharged in stable condition. This series demonstrates the complex nature of the critically anemic JW population and highlights the clinical considerations of using HBOCs in clinical practice and the critical need for further research before they can be broadly recommended.

Abstract
Pulse oximetry is a ubiquitous optical technology, widely used for diagnosis and treatment guidance. Current pulse oximeters provide indications of arterial oxygen saturation. We present here a new quantitative methodology that extends the capability of pulse oximetry and provides real-time molar concentrations of oxy- and deoxy-hemoglobin at rates of up to 27 Hz by using advanced digital hardware, real-time firmware processing, and ultra-fast optical property calculations with a deep neural network (DNN). The technique utilizes a high-speed frequency domain spectroscopy system with five frequency-multiplexed wavelengths. High-speed demultiplexing and data reduction were performed in firmware. The DNN inversion algorithm was benchmarked as five orders of magnitude faster than conventional iterative methods for optical property extractions. The DNN provided unbiased optical property extractions, with an average error of 0 ± 5.6% in absorption and 0 ± 1.4% in reduced scattering. Together, these improvements enabled the measurement, calculation, and real-time continuous display of hemoglobin concentrations. A proof-of-concept cuff occlusion measurement was performed to demonstrate the ability of the device to track oxy- and deoxy-hemoglobin, and measure quantitative photoplethysmographic changes during the cardiac cycle. This technique substantially extends the capability of pulse oximetry and provides unprecedented real-time non-invasive functional information with broad applicability for cardiopulmonary applications.

Abstract
BACKGROUND Jehovah's Witnesses pose a clinical challenge in the setting of critical anemia. Most do not accept transfusions, but some accept hemoglobin-based oxygen carriers on a compassionate-use basis. PEGylated carboxyhemoglobin bovine (PCHB) is an acellular dual-action carbon monoxide (CO)-releasing and oxygen transfer agent currently being investigated in Phase II clinical trials. CASE REPORT We present the case of a 42-year-old Jehovah's Witness with an acute upper gastrointestinal bleed and hemorrhagic shock who required emergent PCHB for stabilization during lifesaving interventions. After PCHB infusion, the patient's shock and encephalopathy improved with decreased vasopressor requirement. Through gastroenterology and interventional radiology procedures, the patient's bleeding stabilized. While receiving five additional doses of PCHB and other supportive therapies (iron, folate, vitamin B12, darbepoetin alfa), the patient was extubated and weaned off vasopressors. CONCLUSIONS PCHB was used to stabilize (bridge) a critically ill anemic patient for lifesaving interventions without adverse effects. Additional studies are warranted to explore the drug's safety profile and efficacy in patients declining blood products.

Abstract
Declining a treatment modality should not be considered the same as refusal of medical care as illustrated by the management of Jehovah's Witness patients who do not accept transfusions. Over the years, a comprehensive set of strategies have been developed to meet the specific needs of these patients and these strategies are collectively called "Bloodless Medicine and Surgery" (BMS). The focus in BMS is to optimize the patients' hematopoietic capacity to increase hemoglobin (Hgb) level, minimize blood loss, improve hemostasis, and provide supportive strategies to minimize oxygen consumption and maximize oxygen utilization. We present 3 case reports that illustrate some of the challenges faced and measures available to effectively treat these patients. Under BMS programs, patients with extremely low hemoglobin levels, not conducive to survival under ordinary conditions, have survived and recovered without receiving allogeneic transfusions. Additionally, the valuable experience gained from caring for these patients has paved the way to develop the concept of Patient Blood Management as a standard care to benefit all patients, and not only those for whom blood is not an option.

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 acquired and congenital heart disease developed by the Pediatric Critical Care Transfusion and Anemia Expertise Initiative. DESIGN Consensus conference series of 38 international, multidisciplinary experts in RBC transfusion management of critically ill children. METHODS Experts developed evidence-based and, when evidence was lacking, expert-based clinical recommendations and research priorities for RBC transfusions in critically ill children. The cardiac disease subgroup included three 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 Twenty-one recommendations were developed and reached agreement. For children with myocardial dysfunction and/or pulmonary hypertension, there is no evidence that transfusion greater than hemoglobin of 10 g/dL is beneficial. For children with uncorrected heart disease, we recommended maintaining hemoglobin greater than 7-9.0 g/dL depending upon their cardiopulmonary reserve. For stable children undergoing biventricular repairs, we recommend not transfusing if the hemoglobin is greater than 7.0 g/dL. For infants undergoing staged palliative procedures with stable hemodynamics, we recommend avoiding transfusions solely based upon hemoglobin, if hemoglobin is greater than 9.0 g/dL. We recommend intraoperative and postoperative blood conservation measures. There are insufficient data supporting shorter storage duration RBCs. The risks and benefits of RBC transfusions in children with cardiac disease requires further study. CONCLUSIONS We present RBC transfusion management recommendations for the critically ill child with cardiac disease. Clinical recommendations emphasize relevant hemoglobin thresholds, and research recommendations emphasize need for further understanding of physiologic and hemoglobin thresholds and alternatives to RBC transfusion in subpopulations lacking pediatric literature.

Abstract
BACKGROUND Elective liver resection (LR) in Jehovah's Witness (JW) patients, for whom transfusion is not an option, involves complex ethical and medical issues and surgical difficulties. METHODS Consecutive data from a LR program for liver tumors in JWs performed between 2014 and 2017 were retrospectively reviewed. A systematic review of the literature with a pooled analysis was performed. RESULTS Ten patients were included (median age = 61 years). None needed preoperative erythropoietin. Tumor biopsy was not performed. Major hepatectomy was performed in 4 patients. The median estimated blood loss was 200 mL. A cell-saver was installed in 2 patients, none received saved blood. The median hemoglobin values before and at the end of surgery were 13.4 g/dL and 12.6 g/dL, respectively (p = 0.04). Nine complications occurred in 4 patients, but no postoperative hemorrhage occurred. In-hospital mortality was nil. Nine studies including 35 patients were identified in the literature; there was reported no mortality and low morbidity. None of the patients were transfused. CONCLUSIONS By using a variety of blood conservation techniques, the risk/benefit ratio of elective liver resection for liver was maintained in selected adult JW patients. JW faith should not constitute an absolute exclusion from hepatectomy.

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.
