    The HIV-1 pandemic is a complex mix of diverse epidemics within and between countries and regions of the world, and is undoubtedly the defining public-health crisis of our time. Any therapeutic or prophylactic measure which holds promise or provides clues of eliminating or inhibiting the infection is worthy of investigation. As our body's own saliva is suspiciously escaping from the infection and providing clues regarding the resistance/inhibition of HIV; in this paper, a treatment approach is suggested with the rationale of in vitro effective antiviral action of autogenous saliva may also have a better therapeutic potential by its intravenous administration along with dextran.

    We report the case of a 36-year old pregnant woman with a Kell alloimmunization (anti-K1), probably secondary to a previous blood transfusion, and a severe hemolytic disease of the fetus. Once the first fetal blood transfusion by cordocentesis was performed, we started treatment with repeated plasmapheresis to maintain anti-K1 titer below 1:32. With this scheme we did not need to perform a second intrauterine fetal blood transfusion and only mild anemia was found in the newborn. Taking into account that the rate of serious complications with plasmapheresis is lower than that related with intrauterine blood transfusion, this could be an alternative approach to repeated transfusions.

    Intrauterine transfusion is the standard of care in the management of severe Rh isoimmunization. Desferrioxamine has been used for the treatment of iron overload secondary to hemolysis and intrauterine transfusions in Rh isoimmunization cases. Here, we report a preterm infant born at 34 weeks of gestational age who had formerly received intrauterine transfusions for Rhesus hemolytic disease and presented with severe hyperferritinemia and elevated liver enzymes in the first week of life. Desferrioxamine treatment was started due to a ferritin level of 28,800 ng/ml and continued for 13 weeks. Although the treatment was successful, we observed resistant leukopenia which resolved after the cessation of treatment. In conclusion, iron overload secondary to intrauterine transfusions can be treated successfully with desferrioxamine; however, neonatologists must be aware of the possible side effects of this drug which has been used in only a limited number of newborns.

    Blood transfusion requirement represents one of the most significant cost driver associated with acute myeloid leukemia (AML). Low-intensity treatments (low-dose cytarabine, hypomethylating agents) have the potential to reduce transfusion dependence, and improve health-related quality of life. We assessed the cost-effectiveness of treatment types regarding blood product transfusions in a cohort of 214 AML patients aged ≥ 70 years. Analyzes did not indicate any significant overall survival (OS) advantage of intensive chemotherapy comparatively to low-intensity treatment. The difference was significant when compared to best supportive care (BSC) (Ptransfusion cost per patient was 1.3 times lower with low-intensity therapy and 2.7 times lower with BSC than with intensive chemotherapy. Mean transfusion cost per patient according to OS varied from 2.4 to 1.3 times less with low-intensity treatment comparatively to intensive chemotherapy for patients having OS ≤ 13.3 months. Costs varied from 3.5 to 2.6 times less with BSC comparatively to intensive chemotherapy. In contrast, mean transfusion costs were comparable among treatments for patients with OS>13.3 months. Low-intensity treatments represent a cost-effective alternative to BSC and require a reduced number of transfused blood products comparatively to intensive chemotherapy, while OS was not significantly different.

    Major burn surgery causes large hemorrhage and coagulation dysfunction. Treatment algorithms guided by ROTEM ® and factor VIIa reduce the need for blood products, but there is no evidence regarding factor XIII. Factor XIII deficiency changes clot stability and decreases wound healing. This study evaluates the efficacy and safety of factor XIII correction and its repercussion on transfusion requirements in burn surgery. Randomized retrospective study with 40 patients undergoing surgery at the Burn Unit, allocated into Group A those with factor XIII assessment (n = 20), and Group B, those without assessment (n = 20). Erythrocyte transfusion was guided by a hemoglobin trigger of 10g.dL -1 and the other blood products by routine coagulation and ROTEM ® tests. Analysis of blood product consumption included units of erythrocytes, fresh frozen plasma, platelets, and fibrinogen. The coagulation biomarker analysis compared the pre- and post-operative values. Group A (with factor XIII study) and Group B had identical total body surface area burned. All patients in Group A had a preoperative factor XIII deficiency, whose correction significantly reduced units of erythrocyte concentrate transfusion (1.95 vs. 4.05, p = 0.001). Pre- and post-operative coagulation biomarkers were similar between groups, revealing that routine coagulation tests did not identify factor XIII deficiency. There were no recorded thromboembolic events. Correction of factor XIII deficiency in burn surgery proved to be safe and effective for reducing perioperative transfusion of erythrocyte units.

    Full Text Available Transfusion, just as any other medical intervention has both benefits and risks, which should be balanced for each patient so that the benefits outweigh the risks. Blood and its products are considered drugs and hence careful consideration of therapy is essential to minimize the potential adverse reactions. Moreover, alternative modes of treatment should be considered and final decision to transfuse should be based on individual patient evaluation. Reviews of blood transfusion practices have found that most surgical procedures do not require blood transfusion. This review is focused on the transfusion needs of the surgical patients.

    Purpose: Sequential treatment (chemotherapy followed by concomitant chemoradiation; CCRT) is increasingly being used for radical treatment of squamous cell cancer of the head and neck (SCCHN), which results in increased myelosuppression. In this study, we review the incidence of anemia and the effect of a policy of hemoglobin (Hb) maintenance by blood transfusion on disease outcomes in these patients. Methods and Materials: Retrospective review of the records of patients with SCCHN treated with sequential CCRT formed the basis of this study. The incidence of anemia and statistics on blood transfusion were documented. For the purpose of outcome analyses, patients were divided into four categories by (1) transfusion status, (2) nadir Hb concentration, (3) number of transfusion episodes, and (4) number of units of blood transfused (NOUT). Data on 3-year locoregional control (LRC), relapse-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) were analyzed. Results: One hundred and sixty-nine patients were identified. The median follow-up was 23.6 months. The RFS (52% vs. 41%, p = 0.03), DSS (71% vs. 66%, p = 0.02), and OS (58% vs. 42% p = 0.005) were significantly better for patients who did not have a transfusion vs. those who did. The LRC, RFS, DSS, and OS were also significantly better for patients with nadir Hb level >12 vs. 4. Conclusion: Our study seems to suggest that blood transfusion during radical treatment for SCCHN might be detrimental. Further research should be undertaken into the complex interactions among tumor hypoxia, anemia, and the treatment of anemia before making treatment recommendations

    Full Text Available PURPOSE: To report the initial experience in our country with a new technique for twin to twin transfusion syndrome (TTTS treatment, using laser to coagulate the placental vessels responsible for the twin transfusion during gestation. METHODS: Prospective study of eight cases diagnosed with TTTS evaluated in our service from january 2001 to june 2005. Through percutaneous introduction of a 2,0mm diameter fetoscope in the uterine cavity, placental surface vessels where directly visualized. Those identified as responsible for the transfusion were laser coagulated. The procedure combines ultrasonography and fetoscopy, in a so-called sonoendoscopic technique (FETENDO. RESULTS: Among the eight pregnancies evaluated, five cases were submitted to the procedure (10 fetuses. All fetuses survived for at least five weeks after surgery. A total of eight fetuses were born alive and five survived the neonatal period. In a 18 months follow-up after birth, all five are still alive and well and their mean age is now 10,6 months. The total survival rate was 50% and in three pregnancies, at least one fetus survived. CONCLUSIONS: Laser fetoscopy is actually the "gold-standard" treatment of TTTS. Nevertheless is a sophisticated technique that epends of proper training. Our service is the first in our country to offer this therapeutic technique. Our success rate is comparable with the international literature.OBJETIVO: Nosso objetivo é relatar a experiência inicial no país com uma nova técnica de tratamento para a síndrome de transfusão feto-fetal (STT, onde se utiliza o raio laser para coagulação dos vasos placentários responsáveis pela transfusão entre gêmeos durante a gravidez.

    Identification of risk factors for requiring transfusions during surgery for colorectal cancer may lead to preventive actions or alternative measures, towards decreasing the use of blood components in these procedures, and also rationalization of resources use in hemotherapy services. This was a retrospective case-control study using data from 383 patients who were treated surgically for colorectal adenocarcinoma at 'Fundação Pio XII', in Barretos-SP, Brazil, between 1999 and 2003. To recognize significant risk factors for requiring intraoperative blood transfusion in colorectal cancer surgical procedures. Univariate analyses were performed using Fisher's exact test or the chi-squared test for dichotomous variables and Student's t test for continuous variables, followed by multivariate analysis using multiple logistic regression.

    Twin-Twin Transfusion syndrome is associated with significant mortality and morbidity. Potential treatments require robust evaluation. The aim of this study was to evaluate outcome reporting across observational studies and randomised controlled trials assessing treatments for twin-twin transfusion syndrome (TTTS). Cochrane Central Register of Controlled Trials, EMBASE and Medline were searched from inception to August 2016. Observational studies and randomised controlled trials reporting outcomes following a treatment for TTTS in monochorionic-diamniotic twin pregnancies and monochorionic-triamniotic or dichorionic-triamniotic triplet pregnancies were included. We systematically extracted and categorised outcome reporting. Six randomised trials and 94 observational studies, reporting data from 20,071 maternal participants and 3,199 children, were included. Six different treatments were evaluated. Included studies reported sixty-two different outcomes, including 10 fetal, 28 neonatal, 6 early childhood and 18 maternal outcomes. The outcomes were inconsistently reported across trials. For example, when considering offspring mortality, 31 studies (31%) reported live birth, 31 studies (31%) reported intrauterine death, 49 studies (49%) reported neonatal mortality, and 17 studies (17%) reported perinatal mortality. Four studies (4%) reported respiratory distress syndrome. Only 19 (19%) of studies were designed for long-term follow-up and 11 of these studies (11%) reported cerebral palsy. Most studies evaluating treatments for TTTS, have often neglected to report clinically important outcomes, especially neonatal morbidity outcomes. Most studies are not designed for long-term follow-up. The development of a core outcome set could help standardised outcome collection and reporting in Twin-Twin Transfusion syndrome studies.

    The surgical treatment of adolescent idiopathic scoliosis can be associated with substantial blood loss, requiring allogeneic red blood cell (RBC) transfusion. This study describes the use of RBC and the effect of a standardized perioperative patient blood management program. Patients treated with posterior instrumented fusion were consecutively enrolled over a 6-year period. Patient blood management strategies were implemented in 2011, including prophylactic tranexamic acid, intraoperative permissive hypotension, restrictive fluid therapy (including avoidance of synthetic colloids), restrictive RBC trigger according to institutional standardized protocol, the use of cell savage, and goal-directed therapy according to thrombelastography. In total, 210 patients were included. 64 patients (31%) received RBC transfusions. A decline in the intraoperative rate of RBC transfusion was observed, from 77% in 2011 to 13% in 2016 (p transfusion group had a significantly larger major curve, lower preoperative hemoglobin, higher estimated blood loss, and an increased use of crystalloid volume resuscitation. Multiple logistic regression showed that significant predictors for RBC transfusion were preoperative hemoglobin level (odds ratio [OR], 0.40; 95% confidence interval [CI], 0.27-0.57), estimated blood loss (OR, 1.26; 95% CI, 1.15-1.42), and year of surgery (indicating the effect of patient blood management) (OR per year, 0.76; 95% CI, 0.58-0.99). A perioperative patient blood management program substantially reduced the need for RBC transfusion. A preoperative evaluation of anemia is essential to further minimize transfusion rates. © 2017 AABB.

    Full Text Available Cees Th. Smit Sibinga ID Consulting, Zuidhorn, The NetherlandsTransfusion Medicine is a bridging science, spanning the evidence-based practice at the bedside with the social sciences in the community.     Transfusion Medicine starts at the bedside. Surprisingly, only recently that has become rediscovered with the development of ‘patient blood management’ and ‘patient centered’ approaches to allow the growth of an optimal and rational patient care through supportive hemotherapy – safe and effective, affordable and accessible.1    Where transfusion of blood found its origin in the need of a patient, it has drifted away for a long period of time from the bedside and has been dominated for almost a century by laboratory sciences. At least the first ten editions of the famous and well reputed textbook Mollison’s Blood Transfusion in Clinical Medicine contained only a fraction on the actual bedside practice of transfusion medicine and did not focus at all on patient blood management.2    This journal will focus on all aspects of the transfusion chain that immediately relate to the bedside practice and clinical use of blood and its components, and plasma derivatives as integral elements of a human transplant tissue. That includes legal and regulatory aspects, medical, ethical and cultural aspects, pure science and pathophysiology of disease and the impact of transfusion of blood, as well as aspects of the epidemiology of blood transfusion and clinical indications, and cost-effectiveness. Education through timely and continued transfer of up to date knowledge and the application of knowledge in clinical practice to develop and maintain clinical skills and competence, with the extension of current educational approaches through e-learning and accessible ‘apps’ will be given a prominent place.

    Blood transfusion is usually meant to lower morbidity and mortality rates. Allogenous blood transfusion implies certain risks that can be avoided by autologous blood transfusions techniques including: preoperatory autologous blood donation, acute normovolemic hemodilution, intraoperatory and postoperatory blood salvage. Preoperatory blood donation and acute normovolemic hemodilution are used for planned interventions with an estimated blood loss higher than 20% of blood volume. These methods imply Erythropoietin and iron treatment. Intraoperatory and postoperatory blood salvage is performed by personnel trained in blood donation, handling and storage. Autologous blood transfusions are used for certain surgical procedures that commonly require transfusions: orthopedic surgery, radical prostatectomy, cardiovascular surgery, organ transplantation. An alternative to allogenous blood transfusion is the use of artificial oxygen transporters: human or animal hemoglobin solutions or pefluorocarbonate solutions. These solutions do not require cross reactions, do not carry diseases and are generally well tolerated and easily stored in the operating room, ambulance and other transport means. They have however a slight degree of toxicity.

We screened 162 women and included 13 (8%). There was no significant difference between groups in fatigue or depression scores. RBC transfusion was associated with a higher Hb on day 1, inhibition of reticulocytosis during the first week and low iron levels. Intravenous iron was associated with increased reticulocytosis during the first week, repleted iron stores and a higher Hb in weeks 3-12. This pilot study shows that intravenous iron could be an attractive alternative to RBC transfusion in severe postpartum anaemia, and that a larger trial is needed and feasible. © 2016 The Authors.

    Massive haemorrhage requires massive transfusion (MT) to maintain adequate circulation and haemostasis. For optimal management of massively bleeding patients, regardless of aetiology (trauma, obstetrical, surgical), effective preparation and communication between transfusion and other laboratory services and clinical teams are essential. A well-defined MT protocol is a valuable tool to delineate how blood products are ordered, prepared, and delivered; determine laboratory algorithms to use as transfusion guidelines; and outline duties and facilitate communication between involved personnel. In MT patients, it is crucial to practice damage control resuscitation and to administer blood products early in the resuscitation. Trauma patients are often admitted with early trauma-induced coagulopathy (ETIC), which is associated with mortality; the aetiology of ETIC is likely multifactorial. Current data support that trauma patients treated with higher ratios of plasma and platelet to red blood cell transfusions have improved outcomes, but further clinical investigation is needed. Additionally, tranexamic acid has been shown to decrease the mortality in trauma patients requiring MT. Greater use of cryoprecipitate or fibrinogen concentrate might be beneficial in MT patients from obstetrical causes. The risks and benefits for other therapies (prothrombin complex concentrate, recombinant activated factor VII, or whole blood) are not clearly defined in MT patients. Throughout the resuscitation, the patient should be closely monitored and both metabolic and coagulation abnormalities corrected. Further studies are needed to clarify the optimal ratios of blood products, treatment based on underlying clinical disorder, use of alternative therapies, and integration of laboratory testing results in the management of massively bleeding patients.

    Full Text Available Background and aims: Recently contact with bioaerosols has been presented as an important problem which endangers human being’s health. The aim of this investigation is to compare potential of separation of fungal aerosols in the air around Tehran’s Milad hospital, blood transfusion organization and waste water treatment plant of Tehran’s Shahrake Ghods. methods: this cross-sectional investigation was done in Milad hospital, blood transfusion organization and Tehran’s Shahrake Ghods waste water treatment plant within for 4 months. The sampling was done passively for 1 hour and once in 6 days. The culture medium was Sabouraud dextrose agar. Results: comparing selected sampling stations the most fungal density was for 100 meters after the last unit of waste water treatment plant (67 CFU and the least density was for Milad hospital (30 CFU. Dominant genera of fungal in waste water treatment plant and blood transfusion organization was related to Cladosporium (in order of 49% and 84% and in air around Milad hospital was related to Alternaria (47%. Conclusion: according to the results processing and operating sections in waste water treatment plant can be effective in fungal density and separation of bioaerosols. Therefore it seems to be vital that the responsible organizations should do necessary actions to develop guidelines and standards related to bioaerosols. Also appropriate administration of environmental health in waste water treatment plant can be an important factor in reduction of aerosol separation.

    Allogeneic platelet transfusions are widely used for the prevention and treatment of bleeding in thrombocytopenia. Recent evidence suggests platelet transfusions have limited efficacy and are associated with uncertain immunomodulatory risks and concerns about viral or bacterial transmission. Alternatives to transfusion are a well-recognised tenet of Patient Blood Management, but there has been less focus on different strategies to reduce bleeding risk by comparison to platelet transfusion. Direct alternatives to platelet transfusion include agents to stimulate endogenous platelet production (thrombopoietin mimetics), optimising platelet adhesion to endothelium by treating anaemia or increasing von Willebrand factor levels (desmopressin), increasing formation of cross-linked fibrinogen (activated recombinant factor VII, fibrinogen concentrate or recombinant factor XIII), decreasing fibrinolysis (tranexamic acid or epsilon aminocaproic acid) or using artificial or modified platelets (cryopreserved platelets, lyophilised platelets, haemostatic particles, liposomes, engineered nanoparticles or infusible platelet membranes). The evidence base to support the use of these alternatives is variable, but an area of active research. Much of the current randomised controlled trial focus is on evaluation of the use of thrombopoietin mimetics and anti-fibrinolytics. It is also recognised that one alternative strategy to platelet transfusion is choosing not to transfuse at all. © 2016 John Wiley & Sons Ltd.

    The aim of this study was to determine the conditions under which a sufficient preoperative amount of autologous blood could be obtained with administration of rHuEPO (recombinant human erythropoietin) in anaemic patients with rheumatoid arthritis (RA). Thirty-one patients (29 female, two male) with RA who were unable to donate any autologous blood owing to a haemoglobin level of less than 11 g/dl were recruited for this study. Their mean age at the time of operation was 59.3 years. The study protocol for preoperative autologous blood donations started 2.7 weeks before surgery. All patients received 6000 IU rHuEPO intravenously three times a week, supplemented with 40 mg intravenous saccharated ferric oxide at each rHuEPO administration. The protocol also included the provision that 200 g of blood at the first and third donations and 400 g of blood at the second donation were collected. The patients who were able or unable to donate 800 g of blood by this protocol were regarded as having a good or poor response, respectively, to rHuEPO. Patients with a poor response to rHuEPO showed greater clinical symptoms (morning stiffness, the number of swollen joints, Ritchie index) and higher laboratory inflammation parameters (ESR, CRP, platelets, IL-6, TNFalpha, IL-1beta) than patients with a good response to rHuEPO. The poor-response group showed a significant decrease in the progression of inflammation compared with the good-response group. Before treatment with rHuEPO, anaemia in the poor-response group was the same as that in the good-response group, except for impairment of UIBC (unsaturated iron-binding capacity). The poor-response group had a higher blood loss than the good-response group. In conclusion, anaemic RA patients should be considered as candidates for aggressive blood conservation interventions that depend on erythropoietin-modulated erythropoiesis. However, it is important to determine this approach under good control of inflammation.

    Traumatic brain injury associated coagulopathy is frequent, either in isolated traumatic brain injury in civilian practice and in combat traumatic brain injury. In war zone, it is a matter of concern because head and neck are the second most frequent site of wartime casualty burden. Data focusing on transfusion requirements in patients with war related TBI coagulopathy are limited. A descriptive analysis was conducted of 77 penetrating traumatic brain injuries referred to a French role 3 medical treatment facility in Kabul, Afghanistan, deployed on the Kabul International Airport (KaIA), over a 30 months period. On 77 patients, 23 died during the prehospital phase and were not included in the study. Severe traumatic brain injury represented 50% of patients. Explosions were the most common injury mechanism. Extracranial injuries were present in 72% of patients. Traumatic brain injury coagulopathy was diagnosed in 67% of patients at role 3 admission. Red blood cell units (RBCu) were transfused in 39 (72%) patients, French lyophilized plasma (FLYP) in 41 (76%), and fresh whole blood (FWB) in 17 (31%). The results of this study support previous observations of coagulopathy as a frequent complication of traumatic brain injury. The majority of patients with war related penetrating traumatic brain injury presented with extracranial lesions. Most of them required a high level of transfusion capacity.

    Hemolytic disease of the fetus and newborn (HDFN) remains a serious pregnancy complication which can lead to severe fetal anemia, hydrops and perinatal death. Areas covered: This review focusses on the current prenatal management, treatment with intrauterine transfusion (IUT) and promising non-invasive treatment options for HDFN. Expert commentary: IUTs are the cornerstone in prenatal management of HDFN and have significantly improved perinatal outcome in the past decades. IUT is now a relatively safe procedure, however the risk of complications is still high when performed early in the second trimester. Non-invasive management using intravenous immunoglobulin may be a safe alternative and requires further investigation.

    Full Text Available Abstract Background Ecthyma gangrenosum (EG manifests as a skin lesion affecting patients suffering extreme neutropenia and is commonly associated with Pseudomonas aeruginosa in immunocompromised patients. Leukocyte adhesion deficiency I (LAD I which count among primary immunodeficiency syndromes of the innate immunity, is an autosomal recessive disorder characterized in its severe phenotype by a complete defect in CD18 expression on neutrophils, delayed cord separation, chronic skin ulcers mainly due to recurrent bacterial and fungal infections, leucocytosis with high numbers of circulating neutrophils and an accumulation of abnormally low number of neutrophils at sites of infection. Case Presentation We report at our knowledge the first case of a child affected by LAD-1, who experienced during her disease course a multi-bacterial and fungal EG lesion caused by fusarium solani. Despite targeted antibiotics and anti-fungi therapy, the lesion extended for as long as 18 months and only massive granulocytes pockets transfusions in association with G-CSF had the capacity to cure this lesion. Conclusion We propose that granulocytes pockets transfusions will be beneficial to heal EG especially in severely immunocompromised patients.

Unfortunately, despite the fact that transfusions are associated with a number of infectious and noninfectious risks, and in spite of the fact that there are ethical, accreditation, and regulatory requirements to provide information regarding transfusion risks, benefits, and alternatives to patients, transfusion consent remains inconsistently obtained. This can partly be attributed to the fact that clinicians may take on a paternalistic approach to transfusion decisions as well as to the fact that many clinicians have knowledge gaps in transfusion medicine that prevent them from obtaining transfusion consent adequately. As a result, unlike the case with other medical and surgical therapies, most patients are not included in the making of informed decisions regarding the need for transfusion versus alternative therapies, leading to many situations in which the transfusions provide little benefit to them. Recently however, a number of organizations, such as the American Association of Blood Banks and The Joint Commission in the US, have promoted multidisciplinary, evidence-based treatment strategies that aim to minimize the need for blood transfusion, the so-called patient blood management (PBM protocols. PBM strategies are expected to improve blood utilization through optimization of patients who may need

    Exposure of blood products to gamma irradiation is currently the standard of care in the prevention of transfusion-associated graft-versus-host disease (TA-GVHD). Regulatory, technical, and clinical challenges associated with the use of gamma irradiators are driving efforts to develop alternatives. Pathogen reduction methods were initially developed to reduce the risk of microbial transmission by blood components. Through modifications of nucleic acids, these technologies interfere with the replication of both pathogens and white blood cells (WBCs). To date, systems for pathogen and WBC inactivation of products containing red blood cells are less well established than those for platelets and plasma. In this study, the in vitro and in vivo function of WBCs present in whole blood after exposure to riboflavin plus ultraviolet light (Rb-UV) was examined and compared to responses of WBCs obtained from untreated or gamma-irradiated blood by measuring proliferation, cytokine production, activation, and antigen presentation and xenogeneic (X-)GVHD responses in an in vivo mouse model. In vitro studies demonstrated that treatment of whole blood with Rb-UV was as effective as gamma irradiation in preventing WBC proliferation, but was more effective in preventing antigen presentation, cytokine production, and T-cell activation. Consistent with in vitro findings, treatment with Rb-UV was as effective as gamma irradiation in preventing X-GVHD, a mouse model for TA-GVHD. The ability to effectively inactivate WBCs in fresh whole blood using Rb-UV, prior to separation into components, provides the transfusion medicine community with a potential alternative to gamma irradiation. © 2012 American Association of Blood Banks.

  9. Transfusion practices in trauma

    Full Text Available Resuscitation of a severely traumatised patient with the administration of crystalloids, or colloids along with blood products is a common transfusion practice in trauma patients. The determination of this review article is to update on current transfusion practices in trauma. A search of PubMed, Google Scholar, and bibliographies of published studies were conducted using a combination of key-words. Recent articles addressing the transfusion practises in trauma from 2000 to 2014 were identified and reviewed. Trauma induced consumption and dilution of clotting factors, acidosis and hypothermia in a severely injured patient commonly causes trauma-induced coagulopathy. Early infusion of blood products and early control of bleeding decreases trauma-induced coagulopathy. Hypothermia and dilutional coagulopathy are associated with infusion of large volumes of crystalloids. Hence, the predominant focus is on damage control resuscitation, which is a combination of permissive hypotension, haemorrhage control and haemostatic resuscitation. Massive transfusion protocols improve survival in severely injured patients. Early recognition that the patient will need massive blood transfusion will limit the use of crystalloids. Initially during resuscitation, fresh frozen plasma, packed red blood cells (PRBCs and platelets should be transfused in the ratio of 1:1:1 in severely injured patients. Fresh whole blood can be an alternative in patients who need a transfusion of 1:1:1 thawed plasma, PRBCs and platelets. Close monitoring of bleeding and point of care coagulation tests are employed, to allow goal-directed plasma, PRBCs and platelets transfusions, in order to decrease the risk of transfusion-related acute lung injury.

    Outcomes data in medicine can be limited by subjective methodologic issues such as poor selection of end points and use of nonvalidated systems for quality adjustment. Blood transfusion analyses are further complicated by the fact that transfusion seldom is primary therapy but is usually supportive or adjunctive. Thus, much of the outcome data in transfusion medicine are either unavailable or in one of two areas. The first area is prevention of bad sequelae of various cytopenias or factor deficiencies. The second is decreasing adverse effects of transfusion itself. A different useful area for outcome and root cause approaches in individual institutions is examining preanalytical and postanalytical processes of their own. Examples are sample labeling accuracy, quality and timeliness of blood suppliers, internal delivery processes and times, and product wastage. Use review can be changed to real time from retrospective time. By reducing complaints about service to objective data, realistic change can be made in internal and external processes.

    Full Text Available Transfusion medicine has been constantly evolving through the years with improved technologies that enhance the capability of identifying existing and newer emerging transfusion transmissible infections (TTI. In spite of the efforts made by blood banks the risk of TTI remains. This article deals with the various steps involved in ensuring blood safety, i.e. donor selection, role of screening donated blood for known and emerging infections, issues and assessment of threat posed by the risk, methodologies employed for testing and possible suggestions to improve transfusion services. While the threat of TTI remains, with a concerted effort of private and government organisations, and co-operation from the diagnostic companies, it is possible to raise the levels of blood safety. A surveillance system is also essential to identify any new agents that might pose a threat in a geographic area and to include them too in the screening process.

    Biochemical investigations on the regulatory mechanisms of red blood cell (RBC) and platelet (PLT) metabolism have fostered a century of advances in the field of transfusion medicine. Owing to these advances, storage of RBCs and PLT concentrates has become a lifesaving practice in clinical and military settings. There, however, remains room for improvement, especially with regard to the introduction of novel storage and/or rejuvenation solutions, alternative cell processing strategies (e.g., pathogen inactivation technologies), and quality testing (e.g., evaluation of novel containers with alternative plasticizers). Recent advancements in mass spectrometry-based metabolomics and systems biology, the bioinformatics integration of omics data, promise to speed up the design and testing of innovative storage strategies developed to improve the quality, safety, and effectiveness of blood products. Here we review the currently available metabolomics technologies and briefly describe the routine workflow for transfusion medicine-relevant studies. The goal is to provide transfusion medicine experts with adequate tools to navigate through the otherwise overwhelming amount of metabolomics data burgeoning in the field during the past few years. Descriptive metabolomics data have represented the first step omics researchers have taken into the field of transfusion medicine. However, to up the ante, clinical and omics experts will need to merge their expertise to investigate correlative and mechanistic relationships among metabolic variables and transfusion-relevant variables, such as 24-hour in vivo recovery for transfused RBCs. Integration with systems biology models will potentially allow for in silico prediction of metabolic phenotypes, thus streamlining the design and testing of alternative storage strategies and/or solutions. © 2015 AABB.

    Blood transfusion is progressing, Europe is growing, European blood transfusion organisations are developing rapidly. The first step was the publication of a new directive (2002/98/CE). The directive is the result of a compromise between technocracy, lobbying and blood transfusion professionals. European blood transfusion must be based on medical, scientific and social criteria. Two imperatives must be considered: the respect of ethics and; independence from the commercial system. The primary objective is to give satisfaction to patients while respecting blood donors.

    Preterm very-low-birth-weight (VLBW) infants weighing eliminated by reducing laboratory blood loss in combination with pharmacodynamically optimized erythropoietin (Epo) treatment. Twenty-six VLBW ventilated infants receiving RBCTx were studied during the first month of life. RBCTx simulations were based on previously published RBCTx criteria and data-driven Epo pharmacodynamic optimization of literature-derived RBC life span and blood volume data corrected for phlebotomy loss. Simulated pharmacodynamic optimization of Epo administration and reduction in phlebotomy by ≥ 55% predicted a complete elimination of RBCTx in 1.0-1.5 kg infants. In infants 1.0 kg.

  2. Blood transfusion safety: a new philosophy.

    Blood transfusion safety has had a chequered history, and there are current and future challenges. Internationally, there is no clear consensus for many aspects of the provision of safe blood, although pan-national legislation does provide a baseline framework in the European Union. Costs are rising, and new safety measures can appear expensive, especially when tested against some other medical interventions, such as cancer treatment and vaccination programmes. In this article, it is proposed that a comprehensive approach is taken to the issue of blood transfusion safety that considers all aspects of the process rather than considering only new measures. The need for an agreed level of safety for specified and unknown risks is also suggested. The importance of providing care and support for those inadvertently injured as a result of transfusion problems is also made. Given that the current blood safety decision process often uses a utilitarian principle for decision making--through the calculation of Quality Adjusted Life Years--an alternative philosophy is proposed. A social contract for blood safety, based on the principles of 'justice as fairness' developed by John Rawls, is recommended as a means of providing an agreed level of safety, containing costs and providing support for any adverse outcomes. © 2012 The Author.

    Full Text Available This prospective longitudinal study investigated the progression of haematological changes in 32 transfused and 54 non-transfused dogs naturally infected with Babesia rossi over the 1st 6 days following diagnosis and treatment. The effect of patient age on the results of complete blood counts was determined. Haematology data were analysed at presentation and at 24 hours, 3 days and 6 days after presentation. Dogs were treated with diminazene aceturate at diagnosis and a blood transfusion was given if deemed clinically required. Mildly to moderately regenerative normocytic normochromic anaemia was observed in all dogs throughout the study period. Transfused dogs more often had an inflammatory leukogram at presentation and at 24 hours, than dogs that were not transfused. In dogs with a left shift, a concurrent normal or decreased segmented neutrophil count was found more commonly than neutrophilia. Severe thrombocytopenia that resolved within a week was common. Blood transfusion alleviated the anaemia, but had no significant effect on white blood cell or platelet responses. Blood cell responses were not significantly influenced by age. In conclusion, the red blood cell and white blood cell responses were less than expected in dogs with babesiosis, given the degree of anaemia and inflammation present. The magnitude of thrombocytopenia and rapid return of the platelet count to normal suggested a possible immune-mediated mechanism for the thrombocytopenia.

    Full Text Available Azra Raza, Nicholas Iverson, Abdullah M AliThe MDS Center, Columbia University, New York, NY, USAAbstract: Myelodysplastic syndromes are malignant hematopoietic stem cell disorders that present with variable cytopenias and predominantly affect the elderly. Treatment options are limited, with allogeneic transplant being the only potentially curative strategy. Recent mutational profiling studies have led to cataloguing of driver and passenger mutations most commonly affecting the epigenetic regulators and genes involved in RNA splicing. Despite improved understanding of the disease biology, these emerging molecular insights have not led to identification of novel therapeutic strategies. Although several drugs approved in the last decade improve the cytopenias, the relief is temporary, most likely due to the sequential activation of clones. Future advances depend upon identification of signaling pathways in dominant clones and targeting these with agents that might be known but need to be matched to suit the needs of individual patients in a longitudinal, dynamic fashion. Myelodysplastic syndromes are ideally suited for the development of such personalized medicine.Keywords: cancer, epigenetics, iron, MDS, myelodysplasia, splicing

    Purpose: Red blood cell (RBC) transfusions or erythropoietin (EPO) can be used to evade the detrimental effects of anemia during radiotherapy, but the economic consequences of selecting either intervention are not well defined. The RBC transfusion needs during chemoradiotherapy for cervix cancer were quantified to allow comparison of RBC transfusion costs with the projected cost of EPO in this setting. Methods and Materials: For patients receiving pelvic radiotherapy, weekly cisplatin, and brachytherapy, the RBC units transfused during treatment were tallied. RBC transfusion costs per unit included the blood itself, laboratory fees, and expected value (risk multiplied by cost) of transfusion-related viral illness. EPO costs included the drug itself and supplemental RBC transfusions when hemoglobin was not adequately maintained. An EPO dosage based on reported usage in cervix cancer patients was applied. Results: Transfusions were given for hemoglobin <10 g/dL. Among 12 consecutive patients, 10 needed at least 1 U of RBC before or during treatment, most commonly after the fifth week. A total of 37 U was given during treatment, for an average of 3.1 U/patient. The sum total of the projected average transfusion-related costs was $990, compared with the total projected EPO-related costs of $3869. Conclusions: Because no proven clinical advantage has been documented for EPO compared with RBC transfusions to maintain hemoglobin during cervix cancer treatment, for most patients, transfusions are an appropriate and appealingly less expensive option

    What will be the evolution of blood transfusion in the next 10 years? What are the scientific and medical arguments to help the decision makers to propose the developments? Many scientific and clinical studies show that blood substitutes are not ready for use in man. So, for a long time, blood collection in man will still be a necessity to prepare cell concentrates (red blood cells and platelets) and fresh frozen plasma. During this period, blood safety will be based on development of testing technics and preparation processes of blood products. Another major point will be a better clinical use of blood derivates. Cellular therapy will be probably only a way of diversification in blood transfusion centers in partnership with hospitals.

    Transfusion data combined with data automatically recorded in hospital databases provides an outstanding tool for blood utilization reporting. When the reporting is performed with an online analytical processing (OLAP) tool, real time reporting can be provided to blood subscribers. When this data is combined with a common patient classification system, Diagnosis-Related Groups (DRG), it is possible to produce statistical results, that are similar in different institutions and may provide a means for international transfusion bench-marking and cost comparison. We use a DRG classification to describe the transfusion practice in Helsinki University Central Hospital. The key indicators include the percentage of transfused patients, the number of transfused units and costs in different DRG groups, as well as transfusion rates per DRG weighted treatment episodes. Ninety-three per cent of all transfusions could be classified into different DRGs. The largest blood-using DRG group was acute adult leukaemia (DRG 473), which accounted for 10.4% of all transfusion costs. The 13 largest blood consuming DRGs accounted for half the total costs in 1998. Currently, there is a lack of an internationally accepted standardized way to report institutional or national transfusion practices. DRG-based transfusion reporting might serve as a means for transfusion benchmarking and thus aid studies of variations in transfusion practice.

    Studies were conducted on the appearance of cells in recipient bone marrow with chromosome markers after bone marrow transfusion to recipients that had different treatments. Investigators tried to replete the bone marrow CFV spleen at various times after recovery from maximal sublethal doses of x radiation or during continuous exposure to tritiated water. Studies were made on the effect of diverse treatments on the acceptance of bone marrow transfusions as shown by chromosomal markers. Results showed that the bone marrow of animals rescued by transfusion of 4 x 10 6 bone marrow cells will accept from 0 to 25% of the second transfusion of bone marrow cells given one to 4 months after the first transfusion and examined 2 to 3 weeks after the second transfusion. This may be due to the second transfusion filling up empty niches

    A fatal case of transfusion-associated graft-versus-host disease developed in a premature infant after receiving several blood products, including nonirradiated white blood cells. Transfusion-associated graft-versus-host disease can be prevented. Irradiation of blood products is the least controversial and most effective method. Treatment was unsuccessful in most reported cases of transfusion-associated graft-versus-host disease. Therefore irradiation of blood products before transfusing to patients susceptible to transfusion-associated graft-versus-host disease is strongly recommended

    Controversy exists over association of blood transfusions with complications. The purpose was to assess effects of limited transfusions on complication rates and hospital course. Level 1 trauma center. Three hundred seventy-one consecutive patients with Injury Severity Score ≥16 underwent fixation of fractures of spine (n = 111), pelvis (n = 72), acetabulum (n = 57), and/or femur (n = 179). Those receiving >3 units of packed red blood cell were excluded. Fracture type, associated injuries, treatment details, ventilation time, complications, and hospital stay were prospectively recorded. Ninety-eight patients with 107 fractures received limited transfusion, and 119 patients with 123 fractures were not transfused. The groups did not differ in age, fracture types, time to fixation, or associated injuries. Lowest hematocrit was lower in the transfused group (22.8 vs. 30.0, P < 0.0001). Surgical duration (3:23 vs. 2:28) and estimated blood loss (462 vs. 211 mL) were higher in transfused patients (all P < 0.003). Pulmonary complications occurred in 12% of transfused and 4% of nontransfused, (P = 0.10). Mean days of mechanical ventilation (2.51 vs. 0.45), intensive care unit days (4.5 vs. 1.5) and total hospital stay (8.8 vs. 5.7) were higher in transfused patients (all P ≤ 0.006). After multivariate analysis, limited transfusion was associated with increased hospital and intensive care unit stays and mechanical ventilation time, but not with complications. Patients receiving ≤3 units of packed red blood cell had lower hematocrit and greater surgical burden, but no difference in complications versus the nontransfused group. Limited blood transfusions are likely safe, excepting a possible association with longer mechanical ventilation times and hospital stays. Therapeutic level III.

  15. Autologous Blood Transfusion for Postpartum Hemorrhage.

    Greenawalt, Julia A; Zernell, Denise

    Postpartum hemorrhage (PPH) is a leading contributor to maternal morbidity and mortality in the United States and globally. Although the rate of PPH is generally decreasing nationally, severity of PPH appears to be increasing, potentially related to the various comorbidities associated with women of childbearing age. There is increasing evidence of risks associated with allogeneic blood transfusion, which has historically been the classic therapeutic approach for treatment to PPH. Pregnant women are particularly susceptible to the implications of sensitization to red cell antigens, a common sequela to allogenic blood transfusion. Autologous blood transfusion eliminates the potential of communicable disease transmission as well as the conceivable threat of a blood transfusion reaction. Recent technological advances allow cell salvage coupled with the use of a leukocyte filter to be used as an alternative approach for improving the outcome for women experiencing a PPH. Modest changes in standard operating procedure and continued training in use and application of cell salvaged blood may assist in minimizing negative outcomes from PPH. Salvaged blood has been demonstrated to be at least equal and often superior to banked blood. We discuss nursing implications for application of this technology for women with PPH. Continued research is warranted to evaluate the impact that application of cell salvage with filtration has on the patient experiencing a PPH.

An increasing number of institutions appear to be successfully adopting approaches that minimize blood usage for all patients treated for gynecologic malignancies. Preoperative, intraoperative and postoperative measures are required, such as optimization of red blood cell mass, adequate preoperative plan and invasive hemostatic procedures, assisting anesthetic techniques, individualization of anemia tolerance, autologous blood donation, normovolemic hemodilution, intraoperative cell salvage and pharmacologic agents for controlling blood loss. An individualised management plan of experienced personnel adopting a multidisciplinary team approach should be available to establish non-blood management strategies, and not only on demand of the patient, in the field of gynecologic oncology with the use of drugs, devices and surgical-medical techniques.

    Television is a beloved American pastime and a frequent American export. As such, American television shapes how the global public views the world. This study examines how the portrayal of blood transfusion and blood donation on American television may influence how domestic and international audiences perceive the field of transfusion medicine. American television programming of the last quarter-century was reviewed to identify programmes featuring topics related to blood banking/transfusion medicine. The included television episodes were identified through various sources. Twenty-seven television episodes airing between 1991 and 2013 were identified as featuring blood bank/transfusion medicine topics. Although some accurate representations of the field were identified, most television programmes portrayed blood banking/transfusion medicine inaccurately. The way in which blood banking/transfusion medicine is portrayed on American television may assist clinicians in understanding their patient's concerns about blood safety and guide blood collection organisations in improving donor recruitment. © 2013 The Author.

    To determine the role of polymorphonuclear (PMN) leukocyte transfusions in neonates with sepsis, 23 consecutive newborns were prospectively randomly selected during an 18-month period in a treatment plan to receive polymorphonuclear leukocyte transfusions with supportive care or supportive care alone. Thirteen neonates received transfusions every 12 hours for a total of five transfusions. Each transfusion consisting of 15 mL/kg of polymorphonuclear leukocytes was subjected to 1,500 rads of radiation. The polymorphonuclear leukocytes were obtained by continuous-flow centrifugation leukapheresis and contained 0.5 to 1.0 X 10(9) granulocytes per 15 mL with less than 10% lymphocytes. Positive findings on blood cultures were obtained in 14/23 patients and seven were randomly selected for each treatment group. Absolute granulocyte counts were less than 1,500/microL in 13 patients but tibial bone marrow examinations revealed that the neutrophil supply pool was depleted in only three patients. The survival was significantly greater in the treatment group compared with the group that did not receive transfusions

    The rapid spread of severe infections mainly due to resistant pathogens, justifies the search for therapies aiming to restore immune functions severely compromised in patients with hematologic malignancies. Areas covered: The present review summarizes the current knowledge on the role of granulocyte transfusions and colony-stimulating factors as treatment strategy for hematologic patients with serious infectious complications. In addition, a survey among 21 hematologic centers, to evaluate the clinical practice for the use of G-CSF originator and biosimilars was performed. Expert commentary: Granulocyte transfusions with a target dose of at least 1.5-3 × 10 8 cells/kg, may be considered as an approach to bridge the gap between marrow suppression and recovery of granulocytes. G-CSF shortens the period of neutropenia, the hospitalization, the use of antibiotics and the rate of febrile neutropenia (FN) in adult and pediatric patients with non-Hodgkin lymphoma, and in adults with acute myeloid leukemia where these advantages nevertheless, did not translate into a clinical benefit. G-CSF biosimilar showed equivalence or non-inferiority to filgrastim. There are no data supporting the use of GM-CSF, eltrombopag and erythropoietin for preventing or treating infectious complications in patients with hematologic disorders.

    Blood donation is an act of solidarity. Most often, this act is done on a volunteer basis and, depending on countries and circumstances, is not remunerated. The increase in need, the always-greater number of deferral criteria, the safety issues and the changes in the structures of our societies are among the many subjects for ethical debates. Taking these into account, the actors of the transfusion must analyze certain parameters: the value of a donation, the meaning of volunteering, the appropriateness of remunerating the act of giving a part of one's self, no longer as a donation or an expression of altruism and solidarity, but as a commercial act regimented by economic laws.

    2011-12-01

    Full Text Available Thalassemia intermedia (TI is a heterogeneous disease, in terms of both clinical manifestations and underlying molecular defects. Some TI patients are asymptomatic until adult life, whereas others are symptomatic from early childhood. In contrast with patients with Thalassemia major (TM, the severity of anemia is less and the patients do not require transfusions during at least the first few years of life. Many patients with TI, especially older ones, have been exposed to the multiple long-term effects of chronic anemia and tissue hypoxia and their compensatory reactions, including enhanced erythropoiesis and increased iron absorption. Bone marrow expansion and extramedullary hematopoiesis lead to bone deformities and liver and spleen enlargement. Therapeutic strategies in TI are not clear and different criteria are used to decide the initiation of transfusion and chelation therapy, modulation of fetal hemoglobin production, and hematopoietic stem cell transplantation on an individual basis. The clinical picture of well-treated TM patients with regular transfusionchelation therapy is better from TI patients who have not received adequate transfusion therapy. There is a significant role of early blood transfusion to prevent and treat complications commonly associated with TI, such as extramedullary erythropoiesis and bone deformities, autoimmune hemolytic anemia, leg ulcers, gallstones, pseudoxantoma elasticum, hyperuricosuria, gout and pulmonary hypertension, which are rarely seen in thalassemia major. Nowadays, indications of transfusion in patients with TI are chronic anemia (Hb < 7 g/dL, bone deformities, growth failure, extramedullary erythropoiesis, heart failure, pregnancy and preparation for surgical procedures. Conclusion: Adequate (regular or tailored transfusion therapy is an important treatment modality for increasing the quality of life in patients with thalassemia intermedia during childhood. 就临床表象和潜在的分子缺

  7. Blood transfusion: patient identification and empowerment.

    Science.gov (United States)

    Stout, Lynn; Joseph, Sundari

    Positive patient identification is pivotal to several steps of the transfusion process; it is integral to ensuring that the correct blood is given to the correct patient. If patient misidentification occurs, this has potentially fatal consequences for patients. Historically patient involvement in healthcare has focused on clinical decision making, where the patient, having been provided with medical information, is encouraged to become involved in the decisions related to their individualised treatment. This article explores the aspects of patient contribution to patient safety relating to positive patient identification in transfusion. When involving patients in their care, however, clinicians must recognise the diversity of patients and the capacity of the patient to be involved. It must not be assumed that all patients will be willing or indeed able to participate. Additionally, clinicians' attitudes to patient involvement in patient safety can determine whether cultural change is successful.

Due to screening, transmission of infectious diseases has decreased; however, the risk is still present. Various immune reactions are common including simple allergic reactions as well as devastating...... conditions such as transfusion-related acute lung injury and circulatory overload in patients with heart disease. Knowledge of the clinical signs of transfusion-related complications is important for clinicians in order to provide the best possible treatment....

  10. Marrow transfusions into normal recipients

    During the past several years we have explored the transfusion of bone marrow into normal nonirradiated mice. While transfused marrow proliferates readily in irradiated animals, only minimal proliferation takes place in nonirradiated recipients. It has generally been assumed that this was due to the lack of available proliferative sites in recipients with normal marrow. Last year we were able to report that the transfusion of 200 million bone marrow cells (about 2/3 of the total complement of marrow cells of a normal mouse) resulted in 20% to 25% of the recipient's marrow being replaced by donor marrow. Thus we can now study the behavior of animals that have been transfused (donor) and endogenous (recipient) marrow cells, although none of the tissues of either donor or recipient have been irradiated. With these animals we hope to investigate the nature of the peculiar phenomenon of serial exhaustion of marrow, also referred to as the limited self-replicability of stem cells

    Non-transfusion dependent beta thalassaemia is a subset of inherited haemoglobin disorders characterised by reduced production of the beta globin chain of the haemoglobin molecule leading to anaemia of varying severity. Although blood transfusion is not a necessity for survival, it is required when episodes of chronic anaemia occur. This chronic anaemia can impair growth and affect quality of life. People with non-transfusion dependent beta thalassaemia suffer from iron overload due to their body's increased capability of absorbing iron from food sources. Iron overload becomes more pronounced in those requiring blood transfusion. People with a higher foetal haemoglobin level have been found to require fewer blood transfusions. Hydroxyurea has been used to increase foetal haemoglobin level; however, its efficacy in reducing transfusion, chronic anaemia complications and its safety need to be established. To assess the effectiveness, safety and appropriate dose regimen of hydroxyurea in people with non-transfusion dependent beta thalassaemia (haemoglobin E combined with beta thalassaemia and beta thalassaemia intermedia). We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register, compiled from electronic database searches and handsearching of relevant journals. We also searched ongoing trials registries and the reference lists of relevant articles and reviews.Date of last search: 30 April 2016. Randomised or quasi-randomised controlled trials of hydroxyurea in people with non-transfusion dependent beta thalassaemia comparing hydroxyurea with placebo or standard treatment or comparing different doses of hydroxyurea. Two authors independently applied the inclusion criteria in order to select trials for inclusion. Both authors assessed the risk of bias of trials and extracted the data. A third author verified these assessments. No trials comparing hydroxyurea with placebo or standard care were found. However, we included

    Both anemia and blood transfusion could be precipitating factors for delirium; hence in postoperative patients with anemia at high risk for delirium, it is controversial whether transfusion is the best option. The aim of this study is to investigate the association of anemia and delirium and the role of blood transfusion within the multicomponent prevention strategy of delirium. We conducted a substudy of a multicenter randomized controlled trial. Four hundred fifteen patients aged 65 to 102 years old admitted for hip fracture surgery were enrolled. Delirium was assessed daily using criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. Data on hemoglobin values and transfusion were collected from the electronic medical records. One hundred fifteen (32.5%) patients experienced delirium during hospitalization, 238 (57.5%) had a hemoglobin level ≤ 6.0 mmol/L (9.7 g/dL) at any time during hospitalization, and 140 (33.7%) received a blood transfusion. Anemia (a hemoglobin level ≤ 6.0 mmol/L [9.7 g/dL]) was associated with delirium (odds ratio, 1.81; 95% confidence interval, 1.15-2.86). Blood transfusion was a protective factor for delirium in patients with the lowest measured hemoglobin level ≤ 6.0 mmol/L (9.7 g/dL) (odds ratio, 0.26; 95% confidence interval, 0.10-0.70). Low hemoglobin level is associated with delirium, and receiving a blood transfusion is associated with a lower delirium incidence. It would be interesting to investigate the effect of blood transfusion as part of the multicomponent treatment of delirium in patients with anemia.

    Full Text Available Transfusion related acute lung injury (TRALI is an uncommon but potentially fatal adverse reaction to transfusion of plasma containing blood components. We describe a case of 10-year-old male child with aplastic anemia, platelet count of 7800/΅l, B positive blood group who developed fever (39.2΀C, difficulty in breathing and cyanosis within 2 hrs after transfusion of a random platelet concentrate. Despite the best resuscitative efforts, the child died within next 24 hrs. The present case highlights the fact that TRALI should be kept as a differential diagnosis in all patients developing acute respiratory discomfort within 6 hrs of transfusion. Without a ′gold standard′ the diagnosis of TRALI relies on a high index of suspicion and on excluding other types of transfusion reactions. Notification to transfusion services is crucial to ensure that a proper investigation is carried out and at-risk donor and recipients can be identified, and risk reduction measures can be adopted.

    Blood transfusion is required in a number of emergency settings and the French military health service (FMHS) has issued specific guidelines for the treatment of war casualties. These guidelines take into account European standards and laws, NATO standards, and also public sentiment regarding transfusion. These guidelines reflect a determination to control the process and to avoid the improvisation frequently associated with wartime transfusion. The evolution in warfare (terrorism and bombing more frequent than gunshot) and the wide use of body armor have deeply changed the clinical presentation of war injuries. These now involve the extremities in 80% of cases, with extensive tissue damage and heavy blood loss. The FMHS recommends that war casualties with hemorrhagic shock be brought quickly to a medical treatment facility (MTF) after first-line treatment applied through buddy aid or by medics. In the MTF, before an early Medevac, a damage control surgery will be performed, with resuscitation using freeze-dried plasma, red blood cells and fresh whole blood. The French military blood bank is responsible for blood product supply, training and medical advice regarding transfusion therapy during wartime, as well as hemovigilance. All transfusion therapy practices are periodically assessed but research on whole blood pathogen reduction is being conducted in order to reduce the residual infectious risk associated with this product.

    Non-transfusion-dependent thalassemias include a variety of phenotypes that, unlike patients with beta (β)-thalassemia major, do not require regular transfusion therapy for survival. The most commonly investigated forms are β-thalassemia intermedia, hemoglobin E/β-thalassemia, and α-thalassemia intermedia (hemoglobin H disease). However, transfusion-independence in such patients is not without side effects. Ineffective erythropoiesis and peripheral hemolysis, the hallmarks of disease process, lead to a variety of subsequent pathophysiologies including iron overload and hypercoagulability that ultimately lead to a number of serious clinical morbidities. Thus, prompt and accurate diagnosis of non-transfusion-dependent thalassemia is essential to ensure early intervention. Although several management options are currently available, the need to develop more novel therapeutics is justified by recent advances in our understanding of the mechanisms of disease. Such efforts require wide international collaboration, especially since non-transfusion-dependent thalassemias are no longer bound to low- and middle-income countries but have spread to large multiethnic cities in Europe and the Americas due to continued migration.

    Combat casualty care has made significant advances in recent years, including administration of blood products in far-forward locations. However, recent studies have shown blood transfusion to be a significant risk factor for infection and increased resource utilization in critically injured patients. We therefore sought to investigate the incidence of blood transfusion and its association with infection and resource utilization in combat casualties. Prospective data were collected and retrospectively reviewed on 210 critically injured patients admitted to the USNS Comfort over a 7-week period during the 2003 assault phase of Operation Iraqi Freedom. Patients were stratified by age, gender, and injury severity score (ISS). Multivariate regression analyses were used to assess blood transfusion and hematocrit (HCT) as independent risk factors for infection and intensive care unit (ICU) admission controlling for age, gender, and ISS. The study cohort had a mean age of 30 +/- 2 years, a mean ISS of 14 +/- 3, 84 per cent were male, and 88 per cent sustained penetrating trauma. Blood transfusion was required in 44 per cent (n = 93) of the study cohort. Transfused patients had a higher ISS (18 +/- 4 vs. 10 +/- 3, P transfused. Patients receiving blood transfusion had an increased infection rate (69% vs. 18%, P transfused and nontransfused patients. Multivariate binomial regression analysis identified blood transfusion and HCT as independent risk factors for infection (P blood transfusion as an independent risk factor for ICU admission (P blood transfusion. Blood transfusion is an independent risk factor for infection and increased resource utilization. Therefore, consideration should be given to the use of alternative blood substitutes and recombinant human erythropoietin in the treatment and management of combat casualties.

    The increasing pressure on healthcare resources affects blood donation and transfusion. We attempted a survey of the efficiency of different strategies, actual or proposed to improve the management of blood products. We found an important disconnect between the cost effectiveness ratio of strategies and their uptake by policy makers. In other words, the least efficient strategies are those which increase transfusion safety by increasing the number of biological markers and are those preferred by health authorities in developed countries. Other more efficient strategies are more slowly implemented and included a systematic use of transfusion guidelines, reducing blood losses or increasing pre operative blood levels in elective surgeries.

    Total ankle arthroplasty (TAA) is an increasingly used, effective treatment for end-stage ankle arthritis. Although numerous studies have associated blood transfusion with complications following hip and knee arthroplasty, its effects following TAA are largely unknown. This study uses data from a large, nationally representative database to estimate the association between blood transfusion and inpatient complications and hospital costs following TAA. Using the Nationwide Inpatient Sample (NIS) database from 2004 to 2014, 25 412 patients who underwent TAA were identified, with 286 (1.1%) receiving a blood transfusion. Univariate analysis assessed patient and hospital factors associated with blood transfusion following TAA. Patients requiring blood transfusion were more likely to be female, African American, Medicare recipients, and treated in nonteaching hospitals. Average length of stay for patients following transfusion was 3.0 days longer, while average inpatient cost was increased by approximately 50%. Patients who received blood transfusion were significantly more likely to suffer from congestive heart failure, peripheral vascular disease, hypothyroidism, coagulation disorder, or anemia. Acute renal failure was significantly more common among patients receiving blood transfusion ( P < .001). Blood transfusions following TAA are infrequent and are associated with multiple medical comorbidities, increased complications, longer hospital stays, and increased overall cost.

    Full Text Available Abstract Introduction Transfusion-related acute lung injury is emerging as a common cause of transfusion-related adverse events. However, awareness about this entity in the medical fraternity is low and it, consequently, remains a very under-reported and often an under-diagnosed complication of transfusion therapy. Case presentation We report a case of a 46-year old woman who developed acute respiratory and hemodynamic instability following a single unit blood transfusion in the postoperative period. Investigation results were non-specific and a diagnosis of transfusion-related acute lung injury was made after excluding other possible causes of acute lung injury. She responded to symptomatic management with ventilatory and vasopressor support and recovered completely over the next 72 hours. Conclusion The diagnosis of transfusion-related acute lung injury relies on excluding other causes of acute pulmonary edema following transfusion, such as sepsis, volume overload, and cardiogenic pulmonary edema. All plasma containing blood products have been implicated in transfusion-related acute lung injury, with the majority being linked to whole blood, packed red blood cells, platelets, and fresh-frozen plasma. The pathogenesis of transfusion-related acute lung injury may be explained by a "two-hit" hypothesis, involving priming of the inflammatory machinery and then activation of this primed mechanism. Treatment is supportive, with prognosis being substantially better than for most other causes of acute lung injury.

    Europe is building up. It develops in a quite complex environment, in which health care represents an important field of activities. As for blood transfusion, it plays a major role especially in the development of medical activities as well as for the patients treatments. Today, blood components are still of human origin and there are no substitutes for them. As a medical discipline, Blood Transfusion represents a broad field in medicine which requests the involvement of numerous actors. It is up to professional medical/scientific societies to promote the discipline. This is why it has been considered necessary and relevant to build up a federation of transfusion medicine societies throughout the European Union (EU) ; it is called EuroNet-TMS, the European Network of Transfusion Medicine Societies. This network groups more than 7500 professionals of involved in blood transfusion activities. It has six major objectives: 1) To find coherent responses to issues at stake in transfusion; 2) To promote medical and scientific developments of blood transfusion in Europe; 3) To ensure the highest and most up-to-date scientific level to meet safety and quality standards; 4) To offer similar services to all EU citizens in the field of blood transfusion; 5) To share knowledge and date within Europe; 6) To develop interfaces with decision-makers among the diverse European countries. The first step is the writing of the "White Book 2005" which reports the state of the art of blood transfusion in Europe; a prospective plan is proposed to be discussed.

    Benchmarking is as a structured continuous collaborative process in which comparisons for selected indicators are used to identify factors that, when implemented, will improve transfusion practices. This study aimed to identify transfusion medicine studies reporting on benchmarking, summarize the benchmarking approaches used, and identify important considerations to move the concept of benchmarking forward in the field of transfusion medicine. A systematic review of published literature was performed to identify transfusion medicine-related studies that compared at least 2 separate institutions or regions with the intention of benchmarking focusing on 4 areas: blood utilization, safety, operational aspects, and blood donation. Forty-five studies were included: blood utilization (n = 35), safety (n = 5), operational aspects of transfusion medicine (n = 5), and blood donation (n = 0). Based on predefined criteria, 7 publications were classified as benchmarking, 2 as trending, and 36 as single-event studies. Three models of benchmarking are described: (1) a regional benchmarking program that collects and links relevant data from existing electronic sources, (2) a sentinel site model where data from a limited number of sites are collected, and (3) an institutional-initiated model where a site identifies indicators of interest and approaches other institutions. Benchmarking approaches are needed in the field of transfusion medicine. Major challenges include defining best practices and developing cost-effective methods of data collection. For those interested in initiating a benchmarking program, the sentinel site model may be most effective and sustainable as a starting point, although the regional model would be the ideal goal.

    Background Blood transfusion is administered during many types of surgery, but its efficacy and safety are increasingly questioned. Evaluation of the efficacy of agents, such as desmopressin (DDAVP; 1-deamino-8-D-arginine-vasopressin), that may reduce perioperative blood loss is needed. Objectives To examine the evidence for the efficacy of DDAVP in reducing perioperative blood loss and the need for red cell transfusion in people who do not have inherited bleeding disorders. Search methods We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (2017, issue 3) in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (from 1937), the Transfusion Evidence Library (from 1980), and ongoing trial databases (all searches to 3 April 2017). Selection criteria We included randomised controlled trials comparing DDAVP to placebo or an active comparator (e.g. tranexamic acid, aprotinin) before, during, or immediately after surgery or after invasive procedures in adults or children. Data collection and analysis We used the standard methodological procedures expected by Cochrane. Main results We identified 65 completed trials (3874 participants) and four ongoing trials. Of the 65 completed trials, 39 focused on adult cardiac surgery, three on paediatric cardiac surgery, 12 on orthopaedic surgery, two on plastic surgery, and two on vascular surgery; seven studies were conducted in surgery for other conditions. These trials were conducted between 1986 and 2016, and 11 were funded by pharmaceutical companies or by a party with a commercial interest in the outcome of the trial. The GRADE quality of evidence was very low to moderate across all outcomes. No trial reported quality of life. DDAVP versus placebo or no treatment Trial results showed considerable heterogeneity between surgical settings for total volume of red cells transfused (low

    A 59-year-old woman who identified as a Jehovah's Witness was diagnosed with pheochromocytoma in the left adrenal gland, measuring 11 cm in diameter, during treatment for hypertension. Given her desire to undergo transfusion-less surgery for religious reasons, we obtained fully informed consent and had the patient sign both a transfusion refusal and exemption-from-responsibility certificate and received consent to instead use plasma derivatives, preoperative diluted autologous transfusion and intraoperative salvaged autologous transfusion. To manage anemia and maintain total blood volume, we preoperatively administered erythropoiesis-stimulating agents and alpha 1 blocker, respectively. During the left adrenalectomy, the patient underwent a transfusion of 400 mL of preoperative diluted autologous blood, ultimately receiving no intraoperative salvaged autologous blood. The operation took 4 hours 42 minutes, and the total volume of blood lost was 335 mL. In conclusion, to complete transfusion-less surgery for pheochromocytoma, it is necessary to have the patient sign a generic refusal form for transfusion and exemption-from-responsibility certificate as well as outline via another consent form exactly what sort of transfusion is permitted on a more specific basis. And doctors should become skilled in perioperative management and operative technique for pheochromocytoma and make the best effort by all alternative medical treatment in order to build trust confidence with a patient.

    Blood transfusion, a practice under re-evaluation in general, remains common among thermal burn patients due to the hematological alterations associated with burns that manifest as anemia. Today advocacy is for restrictive blood transfusion taking into account individual patient characteristics. We went out to identify the parameters that may determine transfusion requirement and the time to blood transfusion for thermal burn patients in Mulago Hospital in order to build statistics and a basis to standardize future practice and Hospital protocol. 112 patients with thermal burns were enrolled into a prospective cohort study conducted in the Surgical Unit of the Accidents and Emergency Department and Burns Unit of Mulago Hospital. Relevant data on pre-injury, injury and post-injury factors was collected including relevant laboratory investigations and treatment modalities like surgical intervention. Patients were clinically followed up for a maximum period of 28 days and we identified those that were transfused. 22.3% of patients were transfused. The median time to transfusion was 17 days from time of injury and varied with different patient characteristics. The median pre-transfusion hemoglobin (Hb) level was 8.2 g/dL. Transfusion was significantly related to; admission to the intensive care unit (p = 0.001), a body mass index (BMI) burn surface area (TBSA) >20 (p = 0.049), pre-existing illness (p = 0.046), and white blood cell (WBC) count 12,000/μL (p = 0.05). Pre-existing illnesses, a low BMI, TBSA of >20%, admission to the intensive care unit and abnormalities in the WBC count are useful predictors of blood transfusion among thermal burns patients admitted to Mulago Hospital. The precise time to transfusion from time of burns injury cannot be generalized. With close monitoring of each individual patient lies the appropriateness and timeliness of their management.

    Because transfusion avoidance has been the cornerstone of anemia treatment for patients with kidney disease, direct measurement of red blood cell transfusion use to assess dialysis facility anemia management performance is reasonable. We aimed to explore methods for estimating facility-level standardized transfusion ratios (STfRs) to assess provider anemia treatment practices. Retrospective cohort study. Point prevalent US hemodialysis patients on January 1, 2009, with Medicare as primary payer and dialysis duration of 90 days or longer were included (n = 223,901). All dialysis facilities with eligible patients were included (n = 5,345). Dialysis facility assignment. Receiving a red blood cell transfusion in the inpatient or outpatient setting. We evaluated 3 approaches for estimating STfR: ratio of observed to expected numbers of transfusions (STfR(obs)), a Bayesian approach (STfR(Bayes)), and a modified version of the Bayesian approach (STfR(modBayes)). The overall national transfusion rate in 2009 was 23.2 per 100 patient-years. Our model for predicting the expected number of transfusions performed well. For large facilities, all 3 STfRs worked well. However, for small facilities, while the STfR(modBayes) worked well, STfR(obs) values demonstrated instability and the STfR(Bayes) may produce more bias. Administration of transfusions to dialysis patients reflects medical practice both within and outside the dialysis unit. Some transfusions may be deemed unavoidable and transfusion practices are subject to considerable regional variation. Development of an STfR metric is feasible and reasonable for assessing anemia treatment at dialysis facilities. The STfR(obs) is simple to calculate and works well for larger dialysis facilities. The STfR(modBayes) is more analytically complex, but facilitates comparisons across all dialysis facilities, including small facilities. Copyright © 2014 National Kidney Foundation, Inc.

    To evaluate the effect of 30-Gy irradiation in conjunction with leukocyte reduction filter on platelet and transfusion efficiency, we studied platelet recovery, leukocyte reduction rate, content of platelet factor 4 and β-thromboglobulin in platelet products, platelet functions, and positive rates of platelet surface membranes CD42 and CD62, prior to and after treatment. We also evaluated the efficiency of platelet transfusion by estimating post- transfusion (1 and 24 hour) corrected count increment (CCI), and transfusion side effects. Recovery of platelets was 91.8±6.5% and depletion rate of leukocytes was 1.7±1.1 log. There was no significant difference in platelet activation markers or function tests prior to and after the procedure. The mean post-transfusion CCI and 1 and 24 hours were 16,550 (n=114) and 13,310 (n=93), respectively, with 30-Gy irradiation and leukocyte reduction filter. Those treated solely with leukocyte reduction filter were 14,970 (n=114) and 10,880 (n=118), respectively. There was no increase in transfusion side effects after the treatment of platelet concentrate with 30-Gy irradiation combined with leukocyte reduction filter compared with treatment by leukocyte reduction filter alone. These results indicate that treatment with 30 Gy irradiation in conjunction with leukocyte reduction filter is safe and effective in platelet transfusion. (author)

    Full Text Available The aim of this study was to improve current transfusion practice in transfusiondependent thalassaemia patients by determining whether safe transition from triplewashed red cells (TWRC to leucodepleted red cells (LDRC, increasing transfusion rates, reducing the use of frusemide and creating uniform practice across patients is possible. In patients receiving regular transfusions (50, triple-washed red blood cells were changed to LDRC, transfusion rates were increased to 5 mL/kg/h (in line with the Cooley’s Foundation guidelines to a maximum of 300 mL/h and frusemide was ceased. Medical review occurred at completion of the transfusion. Of the 20 patients on TWRC, 18 were transitioned to leucodepleted red cells (90%. Recurrent allergic reactions in 2 patients required re-institution of TWRC. 7 of the 8 patients on regular frusemide ceased this practice with no documented transfusion-related fluid overload. One patient refused. Of the eligible 50 patients, 20 patients (40% were increased to the maximum transfusion rate of 300 mLs/h; 6 (12% increased rate but refused to go to the maximum; 9 (18% refused a change in practice and 15 (30% were already at the maximum rate. There was only one documented transfusion reaction (palpitations however this patient was able to tolerate a higher transfusion rate on subsequent transfusions. Thalassemia patients on TWRC were safely transitioned to LDRC. Transfusion rates were safely increased, with a calculated reduction in day-stay bed time of 17.45 h per month. This confirms a guideline of 5 mL/kg/h for transfusion-dependant thalassaemia patients with preserved cardiac function is well tolerated and may be translated to other centres worldwide.   本研究的目的是通过确定是否有可能进行从三洗红细胞(TWRC)到去白细胞红细胞(LDRC)的安全过渡,提高输血速率,减少速尿的使用,并在患者中实施统一规则,从而改进输血依赖型地中海贫血患者中

    BACKGROUND In Mozambique, there is a limited supply of blood and elevated risks for transmission of infections. Prior studies have documented that many transfusions in Mozambique are potentially avoidable. Transfusion training workshops with a survey and exam were held for providers to understand their perceptions and to improve knowledge and clinical practice. STUDY DESIGN AND METHODS Health care providers completed a survey and a knowledge assessment. The Wilcoxon signed rank test was utilized to compare the relative importance of each factor in the survey, and pre- and posttraining exam scores were compared using Fisher’s exact test. RESULTS A total of 216 health care providers participated; the majority worked in a referral hospital (74%) and reported transfusing blood at least once per week (56%). Most acknowledged the limited blood supply and transfusion risks. Providers rated low hemoglobin (Hb) levels and pallor as significantly important indications for transfusion (p transfuse with age under 5 years when compared to other ages (p transfusion practice were increased reliability of the blood supply, education about transfusion indications, and assessment of perfusion. Before training, the majority of participants identified an incorrect Hb threshold for preoperative or critically ill patients. Overall exam scores improved from a mean of 58% to 74% (p blood transfusions. Preoperative patients, the critically ill, and children appear to be at highest risk for receiving an avoidable blood transfusion. These results will help guide planning for future provider training.

    Under examination there were 12 patients aged from 5 till 14 years. An investigation of hemostatic potential of blood in the diseased extremity and peripheral blood was performed. A mosaic character of blood coagulative alterations in this category of patients was detected. Autotransfusion of UV-irradiated blood is a pathogenetically grounded and accessible method of correction of hemocoagulation and may be included in the complex treatment of patients with dysplasia of the profound veins of lower extremities.

    To analyze the different immunohematologic studies required to identify anti-red cell antibodies directed against high incidence antigens and comment the best tranfusion management. Five patients with suspected anti-red cell alloantibodies directed against high frequency antigens are reported. After a positive antibody screening test (AST), an agglutination test with a commercial panel of 24 red cells was performed. Red cells were treated with proteolytic enzymes and AET to try to identify the circulating antibody. However, it was necessary to send the samples to reference laboratories for definitive identification. In order to evaluate the haemolytic potential of the antibody serum samples were treated with DTT and immunoglobulin subtype was studied with the capillary agglutination test. Finally, we analyze the half life of Cr51 labelled red cells. To obtain compatible blood for transfusion, autologous transfusion and cross-match with blood from direct relatives were performed. AST was positive in every case. A decrease in the agglutination test was observed after ficin treatment in two patients, and an increase in the remaining. The treatment of red cells with ZZAP and AET resulted in a decrease of agglutination in three cases and an increase in the remaining two. Specificity of the antibodies was as follows: anti-Cellano (two cases), anti-Ku (one case) and anti-Yta (two cases). Anti-Kell antibodies were IgG1 and anti-Cartwright antibodies were IgG4. One patient was transfused with autologous blood alone, another patient received compatible blood from direct relatives. A third patient was transfused both with autologous and allogeneic compatible blood. The fourth patient did not need red cell transfusion and, finally the last patient had to be transfused with incompatible blood but no postransfusion haemolysis was observed.

    Introduction Factors predictive of the need for red blood cell (RBC) transfusion in the intensive care unit (ICU) have been identified, but risk factors for transfusion after ICU discharge are unknown. This study aims identifies risk factors for RBC transfusion after discharge from the ICU. Methods A prospective, monocentric observational study was conducted over a 6-month period in a 24-bed medical ICU in a French university hospital. Between June and December 2003, 550 critically ill patients were consecutively enrolled in the study. Results A total of 428 patients survived after treatment in the ICU; 47 (11% of the survivors, 8.5% of the whole population) required RBC transfusion within 7 days after ICU discharge. Admission for sepsis (odds ratio [OR] 341.60, 95% confidence interval [CI] 20.35–5734.51), presence of an underlying malignancy (OR 32.6, 95%CI 3.8–280.1), female sex (OR 5.4, 95% CI 1.2–24.9), Logistic Organ Dysfunction score at ICU discharge (OR 1.45, 95% CI 1.1–1.9) and age (OR 1.06, 95% CI 1.02–1.12) were independently associated with RBC transfusion after ICU stay. Haemoglobin level at discharge predicted the need for delayed RBC transfusion. Use of vasopressors (OR 0.01, 95%CI 0.001–0.17) and haemoglobin level at discharge from the ICU (OR 0.02, 95% CI 0.007–0.09; P < 0.001) were strong independent predictors of transfusion of RBC 1 week after ICU discharge. Conclusion Sepsis, underlying conditions, unresolved organ failures and haemoglobin level at discharge were related to an increased risk for RBC transfusion after ICU stay. We suggest that strategies to prevent transfusion should focus on homogeneous subgroups of patients and take into account post-ICU needs for RBC transfusion. PMID:16965637

    Hemorrhagic shock requires early aggressive treatment, including transfusion of packed red blood cells and hemostatic resuscitation. In austere environments, when component therapy is not available, warm fresh whole-blood transfusion is a convenient treatment. It provides red blood cells, clotting factors, and functional platelets. Therefore it is commonly used in military practice to treat hemorrhagic shock in combat casualties. At Bouffard Hospital Center in Djibouti, the supply of packed red blood cells is limited, and apheresis platelets are unavailable. We used whole blood transfusion in two civilian patients with life-threatening non-traumatic hemorrhages. One had massive bleeding caused by disseminated intravascular coagulation due to septic shock; the second was a 39 year-old pregnant woman with uterine rupture. In both cases, whole blood transfusion (twelve and ten 500 mL bags respectively), combined with etiological treatment, enabled coagulopathy correction, hemorrhage control, and satisfactory recovery.

    Blood transfusion is made possible principally by use of donated homologous components that - in turn - can be perceived as sources of danger by recipients. This may create an innate immune response dominated by inflammation, especially when transfusion is repeated. Residual leukocytes in blood components can source inflammatory lesions but considerably less than used to be prior to systematic, early and stringent - in process - leukoreduction. Every blood component can cause inflammation, though barely in the case of therapeutic plasma (in such a case, this is mainly restricted to allergy). Iron that may be freed by red blood cells but also processing and storage lesions such as the emission of microparticles can reveal themselves as pro-inflammatory. Platelets in platelet components represent the main source of inflammatory and/or allergic hazards in transfusion; this is linked with processing and storage lesions but also with the platelet physiology itself. It is of utmost importance to avoid inflammatory adverse events in patients that are fragile because of their primary condition and/or treatment; this stands for their safety, as inflammation can be extremely severe and even lethal, and also for their comfort; this increases efficacy of transfusion programs while reducing the overall costs.

  9. Impact of Transfusion on Cancer Growth and Outcome

    Full Text Available For many years, transfusion of allogeneic red blood cells, platelet concentrates, and plasma units has been part of the standard therapeutic arsenal used along the surgical and nonsurgical treatment of patients with malignancies. Although the benefits of these blood products are not a matter of debate in specific pathological conditions associated with life-threatening low blood cell counts or bleeding, increasing clinical evidence is nevertheless suggesting that deliberate transfusion of these blood components may actually lead to negative clinical outcomes by affecting patient's immune defense, stimulating tumor growth, tethering, and dissemination. Rigorous preclinical and clinical studies are needed to dimension the clinical relevance, benefits, and risks of transfusion of blood components in cancer patients and understand the amplitude of problems. There is also a need to consider validating preparation methods of blood components for so far ignored biological markers, such as microparticles and biological response modifiers. Meanwhile, blood component transfusions should be regarded as a personalized medicine, taking into careful consideration the status and specificities of the patient, rather than as a routine hospital procedure.

    As any therapeutic means, blood transfusion requires regular evaluation, particularly for its indications, effectiveness and risks. The availability of randomized clinical trials, the evolution of the quality of blood components, and the economic constraints shared by all countries, all lead to rethink both transfusion therapy as a whole and the organization of the transfusion chain from donor to recipient. The main tools available to improve transfusion and the transfusion chain management are the following: programs of patient blood management (PBM) to optimize the use of blood products with a patient centred approach, blood supply management tools to improve the effectiveness and efficiency of the transfusion chain, donor management tools to adapt donor collections to the patients' needs in compliance with safety requirements for patients and donors, and coordination of these activities. A better understanding of these tools and their implementation will certainly be major challenges for transfusion medicine in the near future. Integrating these evolutions in regulations through the revision of the European Directives on blood and blood components (the review process is expected to be launched in 2015) should enroll them in the long term, for the benefit of patients, donors and all other stakeholders involved in the transfusion chain.

    Allogeneic blood transfusions have been associated with several risks and complications and with worse outcomes in a substantial number of patient populations and clinical scenarios. Allogeneic blood is costly and difficult to procure, transport, and store. Global and local shortages are imminent. Alternatives to transfusion provide many advantages, and their use is likely to improve outcomes as safer and more effective agents are developed.

    Liver transplantation (LT) was historically associated with massive blood loss and transfusion. Over the past two decades transfusion requirements have reduced dramatically and increasingly transfusion-free transplantation is a reality. Both bleeding and transfusion are associated with adverse outcomes in LT. Minimising bleeding and reducing unnecessary transfusions are therefore key goals in the perioperative period. As the understanding of the causes of bleeding has evolved so too have techniques to minimize or reduce the impact of blood loss. Surgical "piggyback" techniques, anaesthetic low central venous pressure and haemodilution strategies and the use of autologous cell salvage, point of care monitoring and targeted correction of coagulopathy, particularly through use of factor concentrates, have all contributed to declining reliance on allogenic blood products. Pre-emptive management of preoperative anaemia and adoption of more restrictive transfusion thresholds is increasingly common as patient blood management (PBM) gains momentum. Despite progress, increasing use of marginal grafts and transplantation of sicker recipients will continue to present new challenges in bleeding and transfusion management. Variation in practice across different centres and within the literature demonstrates the current lack of clear transfusion guidance. In this article we summarise the causes and predictors of bleeding and present the evidence for a variety of PBM strategies in LT.

    Cord blood, because of its rich mix of fetal and adult hemoglobin, high platelet and white blood cell (WBC) counts, and a plasma filled with cytokine and growth factors, as well as its hypoantigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood transfusion. Our experience of 74 units (50 ml-146 ml mean, 86 ml +/- 7.6 ml SD, median 80 ml, mean packed cell volume 48 +/- 4.1 SD, mean percent hemoglobin concentration 16.2 g/dl +/- 1.8 g/dl of placental umbilical cord whole blood collection (from 1 April 1999) after lower uterine cesarean section (LUCS) from consenting mothers and transfusion of the same to 16 informed, consenting patients with percent plasma hemoglobin 8 g/dl or less, is presented here. After collection the blood was immediately preserved in the refrigerator and transfused within 72 hours of collection. Fifteen males and one female, aged 12-72 yrs (mean 48.4 yrs) participated: five cases were pausibacillary type (PB) and 11 cases were multibacillary type (MB). The clinical spectrum of the cases varied widely from the tuberculoid to the lepromatous type and one patient presented with gangrene of the leg preceding an auto amputation which was infested with maggots. Each case was approved by the institutional ethical committee and received two to eight units of freshly collected placental umbilical cord blood in one transfusion without encountering any clinical, immunological or non-immunological reaction. Seven days after completion of the placental umbilical cord blood transfusion, the peripheral blood hematopoietic stem cell (CD34) estimation revealed a rise from the pretransfusion base level (.09%), varying from 3.6% to 16.2%, in 75% of the cases, without provoking any clinical graft vs host reaction in any of the leprosy victims. This value returned to normal within three months in most cases.

  19. Blood platelet kinetics and platelet transfusion.

    Aster, Richard H

    2013-11-01

    The discovery of citrate anticoagulant in the 1920s and the development of plastic packs for blood collection in the 1960s laid the groundwork for platelet transfusion therapy on a scale not previously possible. A major limitation, however, was the finding that platelet concentrates prepared from blood anticoagulated with citrate were unsuitable for transfusion because of platelet clumping. We found that this could be prevented by simply reducing the pH of platelet-rich plasma to about 6.5 prior to centrifugation. We used this approach to characterize platelet kinetics and sites of platelet sequestration in normal and pathologic states and to define the influence of variables such as anticoagulant and ABO incompatibility on post-transfusion platelet recovery. The "acidification" approach enabled much wider use of platelet transfusion therapy until alternative means of producing concentrates suitable for transfusion became available.

    This study was undertaken to evaluate the association between red blood cell transfusions and infections in an easily stratified, homogenous group of injured adults. All received their initial transfusions upon arrival to the emergency department. Over 5 years, 390 uncross-matched trauma patients received type "O" red blood cells (RBCs) during initial resuscitation. One hundred fifty-four (39%) died within 7 days because of injuries sustained: 236 (61%) survived at least 7 days. Of these 236, clear differences could be seen between those receiving 6 or fewer or 7 or more units of RBCs. When adjusted for age, sex, and severity of injury (Champion Trauma Score, Injury Severity Score, TRISS), the risk of infection was higher in those receiving 7 or more units of RBCs. Similarly, risk of infection was related to units of RBCs transfused in a dose-related fashion. Blood transfusions should be avoided, if possible. Arbitrary "trigger points" for transfusions should be abandoned.

    To develop 2 instruments that predict the probability of perioperative red blood cell transfusion in patients undergoing elective liver resection for primary and secondary tumors. Hepatic resection is the most effective treatment for several benign and malign conditions, but may be accompanied by substantial blood loss and the need for perioperative transfusions. While blood conservation strategies such as autologous blood donation, acute normovolemic hemodilution, or cell saver systems are available, they are economically efficient only if directed toward patients with a high risk of transfusion. Using preoperative data from 1204 consecutive patients who underwent liver resection between 1995 and 2000 at Memorial Sloan- Kettering Cancer Center, we modeled the probability of perioperative red blood cell transfusion. We used the resulting model, validated on an independent dataset (n = 555 patients), to develop 2 prediction instruments, a nomogram and a transfusion score, which can be easily implemented into clinical practice. The planned number of liver segments resected, concomitant extrahepatic organ resection, a diagnosis of primary liver malignancy, as well as preoperative hemoglobin and platelets levels predicted the probability of perioperative red blood cell transfusion. The predictions of the model appeared accurate and with good discriminatory abilities, generating an area under the receiver operating characteristic curve of 0.71. Preoperative factors can be combined into risk profiles to predict the likelihood of transfusion during or after elective liver resection. These predictions, easy to calculate in the frame of a nomogram or of a transfusion score, can be used to identify patients who are at high risk for red cell transfusions and therefore most likely to benefit from blood conservation techniques.

    Anemia of prematurity commonly occurs in infants with very low birth weight; blood transfusion is an important treatment. However, there is no clear evidence to support the criteria currently widely used, based on blood hemoglobin (bHb) and hematocrit indices. Previous studies showed that overtransfusion or a low threshold for transfusion could induce complications or neurologic sequelae, respectively. We hypothesized that a cerebral hemodynamic index may provide an appropriate criterion for determining the need for transfusion in anemic preterm infants. We used near-infrared time-resolved spectroscopy to measure cerebral hemoglobin oxygen saturation (ScO2 ) and cerebral blood volume (CBV) before and after transfusion in 19 infants (24 measurements) with anemia of prematurity. The median gestational age was 27 weeks 0 days, median birth weight was 751 g, and median postconceptual age at transfusion was 30 weeks 4 days. bHb levels before and after transfusion (mean ± SD) were 9.3 ± 1.4 and 13.7 ± 1.3 g/dL, respectively. After transfusion, CBV significantly decreased from 2.63 ± 0.60 to 2.13 ± 0.26 mL/100 g of brain, and ScO2 significantly increased from 72.8 ± 4.3% to 74.7 ± 4.2%. After transfusion, CBV changes were significantly greater with low compared to high pretransfusion Hb levels. This reflected the physiologic response to severe anemia in premature infants, which is to increase CBV and decrease ScO2 . Therefore, CBV and ScO2 may be useful markers for determining the need for transfusion in very-low-birth-weight infants. © 2012 American Association of Blood Banks.

    This study was designed to evaluate the efficacy of exchange transfusion in patients with severe imported falciparum malaria. Twelve patients who met the diagnostic criteria for severe malaria were treated with exchange transfusion 14 times according to a conventional anti-malarial treatment. This study evaluated the efficacy of exchange transfusion for severe imported falciparum malaria. Clinical data of severe imported falciparum malaria patients admitted to the intensive care unit (ICU) of Nantong Third People's Hospital from January 2007 to December 2016 were investigated in this retrospective study. Patients were divided into the intervention group, which received exchange transfusion, and the control group. This study assessed parasite clearance and outcomes of the two groups, and levels of erythrocytes, haemoglobin, platelets, coagulation, liver function, lactate, C-reactive protein, and procalcitonin, before and after exchange transfusion in the intervention group. There was no significant difference in the severity of admitted patients. Exchange transfusion was successfully applied 14 times in the intervention group. Differences in the levels of erythrocytes, haemoglobin and platelets did not reach statistical significance. Exchange transfusion improved coagulation, liver function, lactic acid, C-reactive protein, and procalcitonin. No differences were observed in parasite clearance, ICU and hospital length of stay, in-hospital mortality, and costs of hospitalization between the two groups. Exchange transfusion as adjunctive therapy for severe malaria was observed to be safe in this setting. Exchange transfusion can improve liver function and coagulation and reduce inflammation, but it failed to improve parasite clearance and the outcomes of severe imported falciparum malaria in this case series.

    Cord blood, because of its rich mix of fetal and adult hemoglobin, platelet and WBC counts, and a plasma filled with cytokine and growth factors, as well as its hypoantigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood during emergencies or any etiology of blood loss. In the present study transfusion-related CD34 levels of the peripheral blood from six randomly selected patients suffering from advanced clinical Stage IV malignancy were analyzed between 16 August 1999 and 16 May 2001. This study attempts to ascertain the fate of hematopoietic stem cells (CD34) after placental umbilical cord whole blood transfusion, as assessed from the peripheral blood CD34 level 72 hours after cord blood transfusion in sex- and HLA-randomized patients. Among the six cases, Case 2 (breast sarcoma) received the lowest amount of card blood (6 units), while Case 6 (breast cancer) received the largest amount (32 units). The youngest patient, suffering from non-Hodgkin's lymphoma (Case 3), was a 16-year-old boy who received eight units of cord blood to combat anemia. Other patients received amounts varying from 7-15 units: Case 4 received 15 units (metachronous lymph node metastatsis), Case 1 received 14 units (breast cancer), and Case 5 received seven units (lung cancer). There was no transfusion-related clinical immunological or nonimmunological reaction. Studies of CD34 levels showed an initial rise followed by a fall in two cases, two cases registered very little effect on the CD34 level, i.e., no change from the baseline, and one case demonstrated a very slow rise from the baseline. However, one case showed a frequent steep rise up to 99% and a sustained high CD34 level. This patient is alive with clinical remission of the disease. It appears from this preliminary study that freshly collected cord blood transfusion may cause a transient transplant impact of transfused cord blood CD34 stem cells on the host without

    . Overall mortality rate was 71%(20/28. Up to 28th weeks mortality rate was 100% and after 28th weeks mortality rate was 20%(2/10.9 cases had "stuck" twin phenomenon. The differences in the Doppler indexes from twin-twin transfusion syndrome cases significantly exceeded those without this syndrome. This difference seemed to predict the risk of twin-twin transfusion syndrome, but the number of cases is too small for general conclusions. Treatment regimens for twin-twin transfusion syndrome have included bed rest, tocolytic agents and serial amniocenthesis for decompression in some cases.Neither serial amniocenthesis nor tocolytic agents use were associated with an improved survival rate in our study. Twin-twin transfusion syndrome can be diagnosed early in second trimester of pregnancy,but the survival rate remains low with the current methods of treatment. Survival was related to gestational age at delivery and birth weight. Twin-twin transfusion syndrome diagnosed before 28th weeks of gestation represents one of the most lethal conditions in perinatal medicine today.

    To analyze temporal trends and management of postpartum hemorrhage (PPH) with transfusion and its related maternal near-miss (MNM) cases between 2006 and 2014 and to study risk factors. This retrospective cohort study from two prospective databases included 156,047 women giving birth in all the maternity hospitals of Burgundy. We analyzed temporal trends and the distribution of PPH with transfusion, the circumstances of transfer of patients between hospitals and factors associated with PPH with transfusion. PPH with massive blood transfusion and/or non-medical treatment was defined as MNM. Statistical analysis included Chi 2 tests and logistic regression for multivariate analysis. The overall rate of PPH with transfusion was 7.3‰ and globally increased during the study period whereas the MNM rate did not. MNM represented 37% of patients with PPH with transfusion and 71% of transferred patients, but surgical treatments were performed before transfer. Factors associated with PPH with transfusion were maternal age>35 years (odds ratio [OR]=1.3), prematurity (OR=5.0), cesarean section (OR=4.8), placenta previa (OR=22.0), twin pregnancy (OR=6.6), HELLP syndrome (OR=17.9) and severe small-for-gestational-age infants (OR=2.0). The first four were also associated with MNM. MNM cases of PPH rates were steady in Burgundy while rates of PPH with transfusion increased moderately. Copyright © 2017 Elsevier Masson SAS.

    Despite receiving no or only occasional blood transfusions, patients with non-transfusion-dependent thalassemia (NTDT) have increased intestinal iron absorption and can accumulate iron to levels comparable with transfusion-dependent patients. This iron accumulation occurs more slowly in NTDT patients compared to transfusion-dependent thalassemia patients, and complications do not arise until later in life. It remains crucial for these patients' health to monitor and appropriately treat their iron burden. Based on recent data, including a randomized clinical trial on iron chelation in NTDT, a simple iron chelation treatment algorithm is presented to assist physicians with monitoring iron burden and initiating chelation therapy in this group of patients.

    To determine the triggers of blood transfusion in patients undergoing percutaneous nephrolithotomy (PCNL). The percutaneous surgery database was retrospectively reviewed to identify patients with postoperative haemorrhage and need for blood transfusion. Blood loss was estimated by the postoperative drop in haemoglobin factored by the quantity of any blood transfusion. Various patients and procedure-related factors were assessed for association with total blood loss or blood transfusion requirement using stepwise univariate, forward multivariate regression analysis. A total of 326 procedures were performed in 316 patients. Two hundred and thirty two procedures were included in the study. There were 167 males and 65 females. The mean age was 41+14 years. The mean haemoglobin drop was 1.68 +1.3 gm/dL. The overall blood transfusion rate was 14.2%. Stepwise multivariate regression analysis showed that female gender (p = 0.003), staghorn stone (p = 0.023), stone fragmentation with ultrasound (p = 0.054) and chronic renal failure (p = 0.001) were significantly predictive of the need for blood transfusion. Chronic renal failure, female gender, presence of staghorn calculi and stone fragmentation using ultrasonic device were predictive of blood transfusion in this cohort of patients. (author)

    To report the first four years' clinical experience with fetal intravascular blood transfusion for the treatment of fetal haemolytic anaemia in Western Australia. King Edward Memorial Hospital, Perth, which is the sole tertiary level perinatal centre in Western Australia with a referral base of approximately 25,000 pregnancies each year. Transfusion was by injection of packed cells from Rh-negative donors into the fetal umbilical vein near the site of insertion into the placenta. Fetal haemoglobin levels were measured before and after each transfusion. In most cases, the fetus was paralysed by intramuscular tubocurarine. Sixty intravenous transfusions were performed in 20 pregnancies. At the time of the initial transfusion, the mean haemoglobin level was 5.8 g/dL (range, 2.5-8.5 g/dL) and six fetuses had signs of hydrops. The case survival rate was 80% and the procedure survival rate was 93%. Three of the deaths occurred in the first five cases. Caesarean section was performed during two of the procedures, one because of bleeding from the cord puncture site and one because of tamponade of the umbilical vessels. Fetal intravascular transfusion is a highly effective treatment for fetal alloimmunisation and allows pregnancies to continue to term and to be delivered vaginally. However, the procedure may be difficult and requires a team approach with ready access to fetal monitoring and emergency caesarean section. Our results suggest that increasing experience of the team is a major factor in improved outcome.

    Blood transfusions are frequently prescribed for acute and chronic conditions; however, the extent to which patients' and health care professionals' (HCPs') perceptions of transfusion have been investigated is unclear. Patients' treatment perceptions influence how patients cope with illnesses or symptoms. HCPs' perceptions may influence treatment decision making. This was a systematic review of studies post-1984 reporting adult patients' and HCPs' perceptions of blood transfusion. Seven databases were searched using a three-domain search strategy capturing synonyms relating to: 1) blood transfusion, 2) perceptions, and 3) participant group (patients or HCPs). Study and sample characteristics were extracted and narratively summarized. Reported perceptions were extracted and synthesized using inductive qualitative methods to identify key themes. Thirty-two studies were included: 14 investigated patients' perceptions and 18 HCPs' perceptions. Surgical patients were the highest represented patient group. HCPs were from a wide range of professions. Transfusions were perceived by patients and HCPs as being of low-to-moderate risk. Risk and negative emotions were perceived to influence preference for alternatives. Five themes emerged from the synthesis, classified as Safety/risk, Negative emotions, Alternatives (e.g., autologous, monitoring), Health benefits, and Decision making. "Safety/risk" and "Negative emotions" were most frequently investigated over time, yet periods of research inactivity are apparent. The literature has identified themes on how transfusions are perceived by patients and HCPs, which overlap with recognized discussion points for transfusion specialists. These themes may help HCPs when educating patients about transfusion or consenting patients. Theory-based qualitative methods may add an important dimension to this work. © 2017 AABB.

    Platelet concentrates are given to patients suffering with severe thrombocytopenia usually by a gravity transfusion procedure. Increasing patient numbers that are in need of this treatment increase the pressure on hospital staff and space. In order to combat time issues, the use of medical devices such as intravenous infusion pumps are thought to be beneficial for time and simultaneously for safety in transfusion practices. By using infusion pumps, platelet concentrates can be transfused in less time and provide accurate volume measurements. Manufacturers of infusion pumps claim that these devices are safe to be used for blood products including platelet concentrates. However, published studies were performed on older models and newer devices are on the market now. The purpose of this study is to evaluate infusion pumps, which are claimed to be suitable for blood products and to investigate the impact the pumps had on platelets. Furthermore, the study revealed if the intravenous infusion pumps are safe to be used for platelet transfusion as claimed by manufacturers. A simulated transfusion was performed using the Carefusion Alaris GP Plus volumetric pump and Fresenius Kabi Volumat Agilia infusion pump. Samples were taken from expired platelet concentrates before and after passage through the pump. All samples were investigated for full blood count that included platelet count, mean platelet volume (MPV), platelet distribution width (PDW) and a plateletcrit (PCT). The samples were then centrifuged to achieve platelet-poor plasma and then tested for lactate dehydrogenase (LDH). A power calculation performed on the statistical power analysis program G*power indicated a requirement of 82 samples for a power of 80%. Statistical analysis was performed with the IBM SPSS statistic software. A paired sample t-test was used to calculate mean, standard deviation and P values for the infusion pumps used. The Wilcoxon Signed Rank Test was used to evaluate results that had a non

    Acute leukemia represents the most common cancer in pediatrics. The current treatments made necessary a hematological support which increases the risks of complications, like fever, immunologic reaction, infections and, graft versus host disease. The objective of the present study was to determine the morbidity associated with transfusion support in pediatric patients with acute leukemia. In the pediatric population with diagnosis of acute leukemia in the INC during one and half year, the morbidity associated with transfusions was low and couldn't be related to the treatment given to the transfused products

    To compare the number and volume of red blood cell transfusions (RBCTs) in very low birth weight infants under restrictive red blood cell transfusion guidelines with and without erythropoietin administration. In a controlled clinical trial conducted at the neonatal intensive care unit of Alzahra Hospital, Isfahan, Iran, between April 2002 to April 2004, 60 premature infants with gestational age up to 34 weeks, birth weight up to 1500 g, and postnatal age between 8 and 14 days were included. The newborns were randomized into 2 groups: Group 1 received 3 doses of 400 IU/kg erythropoietin per week for 6 weeks, and Group 2 received no treatment aside from their conventional medications. The 2 groups did not differ significantly with respect to their mean gestational age, birth weight and hematocrit at the study entry. Fewer transfusions were administered to those receiving erythropoietin (26.7% versus 50%, p=0.03), but there was no statistically significant difference between groups with respect to volume of transfusion. Compared with the placebo group, the infants receiving erythropoietin had a higher mean hematocrit (34% +/- 4.3 versus 29% +/- 5.9, p<0.001) and absolute reticulocyte count (57 +/- 19 versus 10 +/- 4.8 x 106, p<0.001) at the end of the study. We found no significant difference in the incidence of thrombocytopenia and leukopenia between the 2 groups. We conclude that when the restrictive RBCT guidelines were followed, treatment with erythropoietin can be useful in reduction of the number of RBCTs. (author)

    Blood doping in sports has been a hot topic of present. Longitudinal follow up of hematological parameters in different endurance sports, during the 1990s and early 2000s, has provided considerable suspicions about extensive blood manipulation, with performance enhancing effects. Recent doping revelations in the media also prove that blood doping is not an anticipated myth but it is, in fact, real. Erythropoiesis stimulating agents and autologous blood transfusions are used in synergy with substantial effect on the maximum oxygen uptake and delivery to muscles. Whilst both methods of blood manipulation represent a potential health hazard, in the context of an elevated hematocrit, nevertheless despite a number of suspicious deaths amongst athletes, this has not yet been fully documented. A reliable test for detection of recombinant human erythropoietin was implemented in 2000, but this is probably circumvented by microdose regimens. The Athlete's Biological Passport represents the progeny of the idea of an indirect approach based on long term monitoring of hematological parameters, thus making it possible to detect autologous blood doping and erythropoietin use after the substance is excreted. Nevertheless with advances in anti-doping measures it is possible that the levels of excretion of substances used can be masked. Clearly more sensitive and specific diagnostic tools and research/development in these areas of major concern are warranted, which, combined with changes in the athlete's attitude, will help in reaching the vision of fair play.

    In France, transfusion medicine training program has been updated. A national committee of professors in transfusion medicine propose a series of 13 items which represent the minimum knowledge that general practitioners should possess. This overview of transfusion medicine is far below the level that specialists should reach and they will need an additional specialized training. Several French universities have set up their own training program which is quite similar to the work of the committee of professors. The following recommendations are not strict guidelines but is a common basis which will be improved in 2005 according to new evidence based transfusion medicine.

    Conclusion: Both criteria of PRBC transfusion had similar clinical outcomes, although liberal transfusion resulted in a greater amount of blood transfused and a low reticulocyte count at 30 days of age. We suggest restrictive criteria for minimizing the overall amount of transfusion to less than 30 mL may be a better way of preventing CLD in VLBW infants.

    Full Text Available Blood transfusion is an essential component of emergency obstetric care and appropriate blood transfusion significantly reduces maternal mortality. Obstetric haemorrhage, especially postpartum haemorrhage, remains one of the major causes of massive haemorrhage and a prime cause of maternal mortality. Blood loss and assessment of its correct requirement are difficult in pregnancy due to physiological changes and comorbid conditions. Many guidelines have been used to assess the requirement and transfusion of blood and its components. Infrastructural, economic, social and religious constraints in blood banking and donation are key issues to formulate practice guidelines. Available current guidelines for transfusion are mostly from the developed world; however, they can be used by developing countries keeping available resources in perspective.

    Cirrhotic patients waiting for liver transplantation who need dental extractions are given fresh frozen plasma and/or platelets to correct coagulopathy. This is costly and may be associated with transfusion reactions and fluid overload. We evaluated the efficacy of intranasal desmopressin as an alternative to transfusion to correct the coagulopathy of cirrhotic patients undergoing dental extraction. Cirrhotic patients with platelet counts of 30,000 to 50,000/microL and/or international normalized ratio (INR) 2.0 to 3.0 were enrolled in a prospective, controlled, randomized clinical trial. Blood transfusion (fresh frozen plasma 10 mL/kg and/or 1 unit of single donor platelets, respectively) or intranasal desmopressin (300 microg) were given before dental extraction. A standard oral and maxillofacial surgical treatment protocol was performed by the same surgeon. Patients were followed for postextraction bleeding and side-effects over the next 24 to 48 hours. No significant differences were noted between the 2 groups in gender, age, INR, platelet count, creatinine, total bilirubin, ALT, albumin, MELD score, or number of teeth removed (median 3 vs 4). The number of teeth removed ranged between 1 and 31 in the desmopressin group and 1 and 22 in the transfusion group. No patients in desmopressin group required rescue blood transfusion after extraction. One patient in the transfusion group had bleeding after the procedure and required an additional transfusion. Another patient experienced an allergic reaction at the end of transfusion, which was effectively treated with diphenhydramine. Treatment associated average costs were lower for desmopressin ($700/patient) compared with transfusion ($1,173/patient). Intranasal desmopressin was as effective as blood transfusion in achieving hemostasis in cirrhotic patients with moderate coagulopathy undergoing dental extraction. Intranasal desmopressin was much more convenient, less expensive, and well tolerated.

  4. Transfusion-transmitted CMV infection - current knowledge and future perspectives.

    Transmission of human cytomegalovirus (CMV) via transfusion (TT-CMV) may still occur and remains a challenge in the treatment of immunocompromised CMV-seronegative patients, e.g. after stem cell transplantation, and for low birthweight infants. Measures to reduce the risk of TT-CMV have been evaluated in clinical studies, including leucocyte depletion of cellular blood products and/or the selection of CMV-IgG-negative donations. Studies in large blood donor cohorts indicate that donations from newly CMV-IgG-positive donors should bear the highest risk for transmitting CMV infections because they contain the highest levels of CMV-DNA, and early CMV antibodies cannot neutralise CMV. Based on this knowledge, rational strategies to reduce the residual risk of TT-CMV using leucoreduced blood products could be designed. However, there is a lack of evidence that CMV is still transmitted by transfusion of leucoreduced units. In low birthweight infants, most (if not all) CMV infections are caused by breast milk feeding or congenital transmission rather than by transfusion of leucoreduced blood products. For other patients at risk, no definitive data exist about the relative importance of alternative transmission routes of CMV compared to blood transfusion. As a result, only the conduction of well-designed studies addressing strategies to prevent TT-CMV and the thorough examination of presumed cases of TT-CMV will achieve guidance for the best transfusion regimen in patients at risk. © 2017 British Blood Transfusion Society.

    The necessity of red blood cell (RBC) transfusions in neurosurgical procedures is under debate. Although detailed recommendations exist for many other surgical disciplines, there are very limited data on the probability of transfusions during neurosurgical procedures. Three-thousand and twenty-six consecutive adult patients undergoing neurosurgical procedures at Saarland University Hospital from December 2006 to June 2008 were retrospectively analyzed for administration of RBCs. The patients were grouped into 11 main diagnostic categories for analysis. The transfusion probability and cross-match to transfusion ratio (C/T ratio) were calculated. Overall, the transfusion probability for neurosurgical procedures was 1.7 % (52/3,026). The probability was 6.5 % for acute subdural hematoma (7/108), 6.2 % for spinal tumors (5/80), 4.6 % for intracerebral hemorrhage (ICH, 4/98), 2.8 % for abscess (3/108), 2.4 % for traumatic brain injury (4/162), 2.3 % for cerebral ischemia (1/44), 1.9 % for subarachnoid hemorrhage (SAH) /aneurysms (4/206), 1.4 % for brain tumors (10/718), 0.8 % for hydrocephalus (2/196), 0.4 % for degenerative diseases of the spine (5/1290), including 3.6 % (3/82) for posterior lumbar interbody fusion (PLIF) and 0 % for epidural hematoma (0/15). The transfusion probabilities for clipping and coiling of SAH were 2.9 % (2/68) and 1.7 % (2/120) respectively. The probability of blood transfusion during neurosurgical procedures is well below the 10 % level which is generally defined as the limit for preoperative appropriation of RBCs. Patients with spinal tumors, acute subdural hematomas or ICH, i.e., patients undergoing large decompressive procedures of bone or soft tissue, had a higher probability of transfusion.

    Blood components and plasma derivatives are two of the most useful tools in modern medicine. When the Portuguese opened the maritime routes to the Far East in the 16th century. Western medicine traveled to Japan on the trading vessels that carried physicians and barber-surgeons to care for the body and Christian missionaries to care for the soul. Skilled interpreters such as Kōgyū Yoshio translated and studied Dutch editions of early medical books, like Lorenz Heister's "Chirurgie" (Nürnberg, 1719), that illustrate the concept of transfusion. The oldest description of transfusion originating in Japan is a handwritten manuscript entitled "Bansui Sensi Chojutsu Shomoku" by Masamichi Nishijima, a student of Bansui Otsuki. It is a list of Otsuki's translated works. He described book names and chapter names in the manuscript, and when he finished translation of a chapter, he marked a circle on the chapter name. The transfusion chapter had a circle. That dates the earliest writing on transfusion in Japanese to 1804, shortly after the death of Kōgyū. Unfortunately, the manuscript translation no longer exists. In 1814, Shunzō Yoshio, grandson of Kōgyū, and in 1820, Tokki Koshimura, translated the figure legends of "Chirurgie." Soon afterwards, after the first report of transfusion from human-to-human by James Blundell in London in 1818, Western medical books published on the subject began to arrive. The works of Christoph Wilhelm Hufeland, Georg Friedrich Most and Carl Canstatt all mentioning transfusion, albeit without details, were translated by Kōan Ogata and Shinryō Tsuboi. During the Edo period, Japan was a closed country; only open to the Dutch through a tiny island in Nagasaki. But Japanese doctors in the Edo period learned about blood transfusion through Dutch-translated versions of Western medical Books. Transfusion began being practiced in Japan in 1919, almost exactly 100 years after the concept was introduced

    Currently, there is little information about the need for peri-operative blood transfusion in patients undergoing shoulder arthroplasty. The purpose of this study was to identify the rate of transfusion and its predisposing factors, and to establish a blood conservation strategy. We identified all patients who had undergone shoulder arthroplasty at our hospital between 1 January 2011 and 31 December 2013. The rate of transfusion was determined from the patient's records. While there were exceptions, patients typically underwent transfusion if they had a level of haemoglobin of transfusion. High- and low-risk cohorts for transfusion were identified from a receiver operating characteristic (ROC) curve. Of 1174 shoulder arthroplasties performed on 1081 patients, 53 cases (4.5%) required transfusion post-operatively. Predictors of blood transfusion were a lower pre-operative haematocrit (p transfusion. In total 48 of the 436 (11%) shoulder arthroplasties with a pre-operative haematocrit transfusion compared with five of the 738 (0.70%) shoulder arthroplasties with a haematocrit above this level. We found that transfusion was needed less frequently than previously described for shoulder arthroplasty. Patients with a pre-operative haematocrit blood transfusion, while those with a haematocrit above this level are unlikely to require transfusion. The rate of transfusion after shoulder arthroplasty is under 5%, and those with a pre-operative haematocrit greater than or equal to 39.6% have a very low likelihood (transfusion. ©2016 The British Editorial Society of Bone & Joint Surgery.

    Severe anemia is a leading indication for blood transfusion and a major cause of hospital admission and mortality in African children. Failure to initiate blood transfusion rapidly enough contributes to anemia deaths in sub-Saharan Africa. This article examines delays in accessing blood and outcomes in transfused children in Kenyan hospitals. Children admitted with nonsurgical conditions in 10 Kenyan county hospitals participating in the Clinical Information Network who had blood transfusion ordered from September 2013 to March 2016 were studied. The delay in blood transfusion was calculated from the date when blood transfusion was prescribed to date of actual transfusion. Five percent (2,875/53,174) of admissions had blood transfusion ordered. Approximately half (45%, 1,295/2,875) of children who had blood transfusion ordered at admission had a documented hemoglobin transfusions, 82% were administered and documented in clinical records, and three-quarters of these (75%, 1,760/2,352) were given on the same day as ordered but these proportions varied from 71% to 100% across the 10 hospitals. Children who had a transfusion ordered but did not receive the prescribed transfusion had a mortality of 20%, compared with 12% among those transfused. Malaria-associated anemia remains the leading indication for blood transfusion in acute childhood illness admissions. Delays in transfusion are common and associated with poor outcomes. Variance in delay across hospitals may be a useful indicator of health system performance. © The American Society of Tropical Medicine and Hygiene.

    The mortality rate caused by organophosphate (OP) poisoning is still high, even the standard treatment such as atropine and oxime improves a lot. To search for alternative therapies, this study was aimed to investigate the effects of packed red blood cell (RBC) transfusion in acute OP poisoning, and compare the therapeutic effects of RBCs at different storage times.Patients diagnosed with OP poisoning were included in this prospective study. Fresh RBCs (packed RBCs stored less than 10 days) and longer-storage RBCs (stored more than 10 days but less than 35 days) were randomly transfused or not into OP poisoning patients. Cholinesterase (ChE) levels in blood, atropine usage and durations, pralidoxime durations were measured.We found that both fresh and longer-storage RBCs (200-400 mL) significantly increased blood ChE levels 6 hours after transfusion, shortened the duration for ChE recovery and length of hospital stay, and reduced the usage of atropine and pralidoxime. In addition, fresh RBCs demonstrated stronger therapeutic effects than longer-storage RBCs.Packed RBCs might be an alternative approach in patients with OP poisoning, especially during early stages.

  10. Bioethics and religious bodies: refusal of blood transfusions in Germany.

    2013-12-01

    The refusal of medical treatment is a recurrent topic in bioethical debates and Jehovah's Witnesses often constitute an exemplary case in this regard. The refusal of a potentially life-saving blood transfusion is a controversial choice that challenges the basic medical principle of acting in patients' best interests and often leads physicians to adopt paternalistic attitudes toward patients who refuse transfusion. However, neither existing bioethical nor historical and social sciences scholarship sufficiently addresses experiences of rank-and-file Witnesses in their dealings with the health care system. This article draws on results of a nine-month (2010, 2011-2012) ethnographic research on the relationship between religious, legal, ethical, and emotional issues emerging from the refusal of blood transfusions by Jehovah's Witnesses in Germany (mainly in Berlin). It shows how bioethical challenges are solved in practice by some German physicians and what they perceive to be the main goal of biomedicine: promoting the health or broadly understood well-being of patients. I argue that two different understandings of the concept of autonomy are at work here: autonomy based on reason and autonomy based on choice. The first is privileged by German physicians in line with a Kantian philosophical tradition and constitutional law; the second, paradoxically, is utilized by Jehovah's Witnesses in their version of the Anglo-Saxon Millian approach.

    Background Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Surgical interventions are more common in people with sickle cell disease, and occur at much younger ages than in the general population. Blood transfusions are frequently used prior to surgery and several regimens are used but there is no consensus over the best method or the necessity of transfusion in specific surgical cases. This is an update of a Cochrane review first published in 2001. Objectives To determine whether there is evidence that preoperative blood transfusion in people with sickle cell disease undergoing elective or emergency surgery reduces mortality and perioperative or sickle cell-related serious adverse events. To compare the effectiveness of different transfusion regimens (aggressive or conservative) if preoperative transfusions are indicated in people with sickle cell disease. Search methods We searched for relevant trials in The Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 23 March 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register: 18 January 2016. Selection criteria All randomised controlled trials and quasi-randomised controlled trials comparing preoperative blood transfusion regimens to different regimens or no transfusion in people with sickle cell disease undergoing elective or emergency surgery. There was no restriction by outcomes examined, language or publication status. Data collection and analysis Two authors independently assessed trial eligibility and the risk of bias and extracted data. Main results Three trials with 990 participants were eligible for inclusion in the review. There were no

    To study whether autologus blood transfusion systems reduce the requirement of allogneic blood transfusion in patients undergoing total knee arthroplasty. A comprehensive search of the published literature with PubMed, Scopus and Science direct database was performed. The following search terms were used: (total knee replacement) OR (total knee arthroplasty) OR (TKA) AND (blood transfusion) OR (autologous transfusion) OR (autologous transfusion system). Using search syntax, a total of 748 search results were obtained (79 from PubMed, 586 from Science direct and 83 from Scopus). Twenty-one randomized control trials were included for this meta-analysis. The allogenic transfusion rate in autologus blood transfusion (study) group was significantly lower than the control group (28.4 and 53.5 %, respectively) (p value 0.0001, Relative risk: 0.5). The median units of allogenic blood transfused in study control group and control group were 0.1 (0.1-3.0) and 1.3 (0.3-2.6), respectively. The median hospital stay in study group was 9 (6.7-15.6) days and control group was 8.7 (6.6-16.7) days. The median cost incurred for blood transfusion per patient in study and control groups was 175 (85.7-260) and 254.7 (235-300) euros, respectively. This meta-analysis demonstrates that the use of auto-transfusion systems is a cost-effective method to reduce the need for and quantity of allogenic transfusion in elective total knee arthroplasty.

    2010-03-01

    Full Text Available Abstract Background Patients suffering from intracerebral haemorrhage have a poor prognosis, especially if they are using antiplatelet therapy. Currently, no effective acute treatment option for intracerebral haemorrhage exists. Limiting the early growth of intracerebral haemorrhage volume which continues the first hours after admission seems a promising strategy. Because intracerebral haemorrhage patients who are on antiplatelet therapy have been shown to be particularly at risk of early haematoma growth, platelet transfusion may have a beneficial effect. Methods/Design The primary objective is to investigate whether platelet transfusion improves outcome in intracerebral haemorrhage patients who are on antiplatelet treatment. The PATCH study is a prospective, randomised, multi-centre study with open treatment and blind endpoint evaluation. Patients will be randomised to receive platelet transfusion within six hours or standard care. The primary endpoint is functional health after three months. The main secondary endpoints are safety of platelet transfusion and the occurrence of haematoma growth. To detect an absolute poor outcome reduction of 20%, a total of 190 patients will be included. Discussion To our knowledge this is the first randomised controlled trial of platelet transfusion for an acute haemorrhagic disease.

    Twin anemia-polycythemia sequence (TAPS) is a rare condition which may occur either spontaneously in uncomplicated monochorionic twin pregnancies or may develop after laser treatment in twin-twin transfusion syndrome. TAPS is characterized by a large intertwin discordance in hemoglobin levels without discordance in amniotic fluid levels, and may lead to severe complications including fetal hydrops, hematological morbidity and perinatal mortality. Several treatments have been proposed including intrauterine transfusion, laser surgery, elective delivery and expectant management. The optimal treatment remains unclear. In this case series we report 3 TAPS cases managed recently at our center with a combination of intrauterine blood transfusion for the anemic twin and intrauterine partial exchange transfusion for the polycythemic twin. In 1 case, the donor was found to have severe cerebral injury on neuroimaging examination. We propose etiologic mechanisms for cerebral injury in TAPS, discuss the rationale behind this treatment alternative, and evaluate the pros and cons of the various management options.

    The representation of blood transfusion and donation of blood in the comic strip has never been studied. The comic strip, which is a relatively recent art, emerged in the 19th century before becoming a mass medium during the 20th century. We have sought, by calling on collectors and using the resources of Internet, comic strips devoted, wholly or in part, to the themes of transfusion and blood donation. We present some of them here in chronologic order, indicating the title, country of origin, year of publication, and names of authors. The theme of the superhero using transfusion to transmit his virtues or his powers is repeated throughout the 20th century in North American comic strips. More recently, comic strips have been conceived from the outset with a promotional aim. They perpetuate positive images and are directed toward a young readership, wielding humor to reduce the fear of venipuncture. Few comic strips denounce the abuse of the commercialization of products derived from the human body. The image of transfusion and blood donation given by the comic strips is not to be underestimated because their readership is primarily children, some of whom will become blood donors. Furthermore, if some readers are transfused during their lives, the impact of a memory more or less conscious of these childhood readings may resurface, both in hopes and in fears.

    Concerns regarding the safety of transfused blood have generated considerable enthusiasm for the use of technologies intended to reduce the use of allogeneic blood (blood from an unrelated donor). Platelet-rich plasmapheresis (PRP) offers an alternative approach to blood conservation. To examine the evidence for the efficacy of PRP in reducing peri-operative allogeneic red blood cell (RBC) transfusion, and the evidence for any effect on clinical outcomes such as mortality and re-operation rates. We identified studies by searching MEDLINE (1950 to 2009), EMBASE (1980 to 2009), The Cochrane Library (Issue 1, 2009), the Internet (to March 2009) and the reference lists of published articles, reports, and reviews. Controlled parallel group trials in which adult patients, scheduled for non-urgent surgery, were randomised to PRP, or to a control group which did not receive the intervention. Primary outcomes measured were: the number of patients exposed to allogeneic RBC transfusion, and the amount of RBC transfused. Other outcomes measured were: the number of patients exposed to allogeneic platelet transfusions, fresh frozen plasma, and cryoprecipitate, blood loss, re-operation for bleeding, post-operative complications (thrombosis), mortality, and length of hospital stay. Treatment effects were pooled using a random-effects model. Trial quality was assessed using criteria proposed by Schulz et al (Schulz 1995). Twenty-two trials of PRP were identified that reported data for the number of patients exposed to allogeneic RBC transfusion. These trials evaluated a total of 1589 patients. The relative risk (RR) of exposure to allogeneic blood transfusion in those patients randomised to PRP was 0.73 (95%CI 0.59 to 0.90), equating to a relative risk reduction (RRR) of 27% and a risk difference (RD) of 19% (95%CI 10% to 29%). However, significant heterogeneity of treatment effect was observed (p transfused (weighted mean difference [WMD] -0.69, 95%CI -1.93 to 0.56 units). Trials

    2003-01-01

    Objective: The study was conducted to evaluate the effects of blood transfusion(s) on the haematological picture of beta-thalassaemia major. Results: Out of the 280 patients 109 (39%) had received one or more blood transfusions (cases). The remaining 171 patients who did not receive any transfusion served as controls. The mean MCV, MCH and Hb-F in cases were significantly higher than in the controls (p 4 transfusions (17%) (p=0.016). In the occasionally transfused patients Hb-F level was directly related to the time since last transfusion. In 44/109 (40%) transfused patients (Hb-F>30%) the diagnosis of thalassaemia was not difficult. In 54/109 (50%) patients (Hb-:5-30%) the diagnosis was aided by parent's study, while PCR for thalassaemia mutation was required in 11/109 (10%) patients (Hb-F <5%). Conclusion: In most transfused patients of thalassaemia major MCV and MCH were significantly higher while Hb-F was lower than in the un-transfused patients. There was a linear correlation between Hb-F level and time since last transfusion in the occasionally transfused patients. However, the reduction in Hb-F level was more marked and sustained in multipally transfused patients. Parent's study and PCR are useful aids in establishing the correct diagnosis in these patients.

    The level of safety attained in blood transfusion now makes this a discipline better managed care activities. This was achieved both by scientific advances and policy decisions regulating and supervising the activity, as well as by the quality system, which we recall that affects the entire organizational structure, responsibilities, procedures, processes and resources in place to achieve quality management. So, an effective quality system provides a framework within which activities are established, performed in a quality-focused way and continuously monitored to improve outcomes. This system quality has to irrigate all the actors of the transfusion, just as much the establishments of blood transfusion than the health establishments. Copyright © 2014 Elsevier Masson SAS.

    Full Text Available Nareg H Roubinian,1,2 Edward L Murphy1–3 1Blood Systems Research Institute, 2Department of Laboratory Medicine, 3Department of Epidemiology and Biostatistics, University of California San Francisco, San Francisco, CA, USA Abstract: Transfusion-associated circulatory overload (TACO is acute pulmonary edema associated with left atrial hypertension or volume overload occurring within 6 hours following a blood transfusion. Recognized by physicians as a common complication of blood transfusion, its incidence has been difficult to measure because active surveillance is required to counteract underreporting; active surveillance indicates overall incidence rates as high as 1% per transfused patient. Recent clinical and translational research has focused on the development of electronic alert systems to measure TACO incidence and provide alerts to physicians regarding patients at high risk. Translational research regarding the utility of biomarkers such as brain natriuretic protein (BNP or N-terminal pro-BNP (NT-proBNP as diagnostic tools for TACO has been only moderately successful, but the search for other biomarkers continues. Prevention strategies can be developed based upon evidence derived from both observational studies and might include: using documented risk factors to highlight patients at risk, preferably using real-time analysis of electronic medical records; implementation of modified transfusion strategies to minimize the volume and infusion rate of blood products; consideration of prophylactic diuretic therapy; and heightened diagnostic awareness combined with rapid implementation of treatment. Randomized clinical trials will be required to test such strategies before they are widely implemented. Finally, the occurrence of TACO ought to be considered as a potentially avoidable medical complication that could be used to benchmark transfusion and critical care practice across hospitals.

    Full Text Available Purpose: To study the ocular manifestations in multiple transfused beta-thalassemia major patients and assess the ocular side-effects of iron chelating agents. Materials and Methods: In this prospective observational study, 45 multiple transfused beta-thalassemia major children between six months and 21 years of age were enrolled and assigned groups according to the treatment regimens suggested. Group A received only blood transfusions, Group B blood transfusions with subcutaneous desferrioxamine, Group C blood transfusions with desferrioxamine and oral deferriprone and Group D blood transfusions with deferriprone. Ocular status at the time of enrolment was documented. Subjects were observed quarterly for one year for changes in ocular status arising due to the disease process and due to iron chelation therapy. Children with hemoglobinopathies other than beta-thalassemia major, congenital ocular anomalies and anemia due to other causes were excluded. Results: Ocular involvement was observed in 58% of patients. Lenticular opacities were the most common ocular finding (44%, followed by decreased visual acuity (33%. An increased occurrence of ocular changes was observed with increase of serum ferritin and serum iron levels as well as with higher number of blood transfusions received. Desferrioxamine seemed to have a protective influence on retinal pigment epithelium (RPE mottling. Occurrence of lenticular opacities and RPE degeneration correlated positively with use of desferrioxamine and deferriprone respectively. Follow-up of patients for one year did not reveal any change in ocular status. Conclusion: Regular ocular examinations can aid in preventing, delaying or ameliorating the ocular complications of thalassemia.

    Blood and its derivatives are one of the most lifesaving products in the modern medicine practice. However, it is not an absolutely safe prescription. Many adverse effects such as infection, transfusion-related acute lung injury, immunosuppression, multi-organ dysfunction, acute respiratory syndrome, transfusion errors, transmission of infectious agents such as HIV, HBV, HCV are attributable to blood transfusion. The aim of this study was to describe how and when blood products were transfused in a referral burn center. This cross-sectional study was performed on medical records of all admitted patients in the Department of Burns and Reconstructive Surgery of Imam Reza Hospital, Mashhad, Iran during September 2014 up to August 2015. Transfusion measures such as Hb, Hct and demographic data were extracted from patient records. SPSS version 11.5 was used for data analysis. During the study period, 701 acute burnt patients were admitted with the mean age of 25.5±20.5 years. Sixty-four percent were male and burnt percentage of total body surface area (TBSA) was 30.9±24.3%. About one third (240) of patients received at least one blood product. Mean of the transfused packed red blood cell was 274.1±674.6mL per patient and 8.85mL per 1% of burnt TBSA. Anemia was the most common transfusion trigger. Mortality in burnt patients who received blood products was two folds more than patients who did not receive any blood products. We prescribed less blood products compared with other reviewed burn centers. However, following a written blood transfusion protocol by all clinicians may reduce blood transfusion in unnecessary situations even more significantly. Copyright © 2017 Elsevier Masson SAS.

    The discovery of citrate anticoagulant in the 1920s and the development of plastic packs for blood collection in the 1960s laid the groundwork for platelet transfusion therapy on a scale not previously possible. A major limitation, however, was the finding that platelet concentrates prepared from blood anticoagulated with citrate were unsuitable for transfusion because of platelet clumping. We found that this could be prevented by simply reducing the pH of platelet-rich plasma to about 6.5 pr...

    Most clinical practice guidelines recommend restrictive red cell transfusion practices, with the goal of minimising exposure to allogeneic blood. The purpose of this review is to compare clinical outcomes in patients randomised to restrictive versus liberal transfusion thresholds (triggers). To examine the evidence for the effect of transfusion thresholds on the use of allogeneic and/or autologous red cell transfusion, and the evidence for any effect on clinical outcomes. We identified trials by searching; The Cochrane Injuries Group Specialised Register (searched 01 Feb 2011), Cochrane Central Register of Controlled Trials 2011, issue 1 (The Cochrane Library), MEDLINE (Ovid) 1948 to January Week 3 2011, EMBASE (Ovid) 1980 to 2011 (Week 04), ISI Web of Science: Science Citation Index Expanded (1970 to Feb 2011), ISI Web of Science: Conference Proceedings Citation Index- Science (1990 to Feb 2011). We checked reference lists of other published reviews and relevant papers to identify any additional trials. Controlled trials in which patients were randomised to an intervention group or to a control group. Trials were included where intervention groups were assigned on the basis of a clear transfusion 'trigger', described as a haemoglobin (Hb) or haematocrit (Hct) level below which a red blood cell (RBC) transfusion was to be administered. Risk ratios of requiring allogeneic blood transfusion, transfused blood volumes and other clinical outcomes were pooled across trials, using a random effects model. Data extraction and assessment of the risk of bias was performed by two people. Nineteen trials involving a total of 6264 patients were identified, and were similar enough that the results could be combined. Restrictive transfusion strategies reduced the risk of receiving a RBC transfusion by 39% (RR 0.61, 95% CI 0.52 to 0.72). This equates to an average absolute risk reduction (ARR) of 34% (95% CI 24% to 45%). The volume of RBCs transfused was reduced on average by 1

    For the past four decades, extracorporeal life support (ECLS) has been used to treat critically ill adult and pediatric patients with cardiac and/or respiratory failure, and there are increasingly numbers of centers worldwide performing ECLS for numerous indications. Despite the progress with advancing the technology, hemorrhagic and thrombotic complications are frequently reported and associated with worse outcomes, but the exact cause is often elusive or multifactorial. As a result of the interaction between blood and an artificial circuit, anticoagulation is necessary and there is resultant activation of coagulation, fibrinolysis, as well as, an increased inflammatory response. While unfractionated heparin (UFH) remains the mainstay anticoagulant used during ECLS, there is a paucity of published data to develop a universal anticoagulation guideline and centers are forced to create individualized protocols to guide anticoagulation management while lacking expertise. From an international survey, centers often use a combination of tests, which in turn result in discordant results and confused management. Studies are urgently needed to investigate optimization of current anticoagulation strategies with UFH, as well as, use of alternative anticoagulants and non-thrombogenic biomaterials. Blood transfusion during extracorporeal support typically occurs for several reasons, which includes circuit priming, restoration of oxygen carrying capacity, maintenance of a hemostatic balance, and treatment of hemorrhagic complications. As a result, the majority of patients will have been exposed to at least one blood product during extracorporeal support and transfusion utilization is high. ECLS Centers have adopted transfusion thresholds based upon practice rather than evidence as there have been no prospective studies investigating the efficacy of red cell (RBC) transfusion in patients receiving extracorporeal support. In addition, RBC transfusion has been associated with

    Full Text Available Extracorporeal membrane oxygenation (ECMO is frequently associated with bleeding and coagulopathy complications, which may lead to the need for transfusion of multiple blood products. However, blood transfusions are known to increase morbidity and mortality, as well as hospital cost, in critically ill patients. In current practice, patients on ECMO receive a transfusion, on average, of 1-5 packed red blood cells (RBCs/day, with platelet transfusion accounting for the largest portion of transfusion volume. Generally, adult patients require more transfusions than neonates or children, and patients receiving venovenous ECMO for respiratory failure tend to need smaller transfusion volumes compared to those receiving venoarterial ECMO for cardiac failure. Observation studies have reported that a higher transfusion volume was associated with increased mortality. To date, the evidence for transfusion in patients undergoing ECMO is limited; most knowledge on transfusion strategies was extrapolated from studies in critically ill patients. However, current data support a restrictive blood transfusion strategy for ECMO patients, and a low transfusion trigger seems to be safe and reasonable.

    Objectives: To assess the effectiveness of intensive phototherapy in reducing the need for exchange transfusion and the duration of phototherapy. Methods: The prospective study with historical controls was conducted at Cairo University Paediatric Hospital, from February to July 2012, and comprised 360 newborns with indirect hyperbilirubinaemia. The 183 subjects were treated with Bilisphere 360 (Bilisphere group) compared with 177 who had been treated with conventional phototherapy (control group). Both groups were subjected to complete clinical evaluation and laboratory investigations. Results: Bilisphere 360 decreased the need for exchange transfusion in 19 (10.4%) neonates of the Bilisphere group versus 130 (73.4%) of the control group (p<0.001); decreased the level of serum bilirubin as exchange transfusion (6.7 mg/dl (24.9%) in the subjects vs. 6.9 mg/dl (22.7%) in the controls); shortened the duration of phototherapy (2.7 days in the subjects, vs. 4.2 days in the controls; p<0.001). Conclusion: The use of Bilisphere 360 in the treatment of indirect pathological hyperbilirubinaemia is as effective as exchange transfusion in lowering Total Serum Bilirubin when its level is within 2-3 mg/dl (34-51umol/l) of the exchange level. Bilisphere 360 is effective in reducing needs for exchange transfusion and duration of phototherapy. (author)

    This study was aimed to review and establish the practice of exchange transfusion (ET) with reconstituted blood in neonates and to observe fall of bilirubin and its comparison with related studies. Twenty-five neonates diagnosed as hemolytic disease of newborn (HDN) were selected for this study, in which exchange transfusion was carried out as one of the treatments for hyperbilirubinemia. Out of the 25 cases, 15 were of Rhesus (Rh) HDN, while ABO and other blood groups constituted 6 and 4 HDN cases respectively. First, the neonates's and mother's blood samples were subjected to relevant investigations. After that, for neonates having Rh HDN, O Rh negative cells suspended in AB plasma were given, O Rh positive cells suspended in AB plasma were given to ABO HDN; and O positive cells, which were indirect Coomb's cross-matched compatible with neonates’ and mother's serum / plasma, suspended in AB plasma were given to the neonates having HDN because of other blood group antibodies. The exchange transfusion (ET) was carried out taking all aseptic precautions by Push-Pull technique with double-volume exchange transfusion method. The average post-exchange fall in serum indirect bilirubin was (52.01%) in all 25 cases, which was found to be more significant than the previous studies. Looking into the superiority of the exchange transfusion in HDN by reconstituted blood, the reconstituted blood can be modified and supplied as per the requirement and conditions. PMID:21938234

  11. Experts: hospitals can improve care, save health care dollars by cracking down on unnecessary blood transfusions.

    2013-01-01

    Leading health care quality organizations say that blood transfusions are among the most overused treatments. The problem wastes a precious resource as well as health care dollars, continues to stretch what is known to be in short supply in some parts of the country. Part of the problem is continued adherence to an outdated medical practice that calls for transfusions when they are not medically necessary. Also, experts say many guidelines are vague regarding hemoglobin triggers. However, education coupled with IT-driven interventions can help hospitals make dramatic improvements in their blood usage, potentially preserving blood products for patients who really need them. The American Red Cross says that blood use rose by 40% in the United States between 1994 and 2008. Studies show there is wide variation regarding when blood transfusions are called for by practitioners. The latest research suggests hemoglobin thresholds of 7 or 8 grams per deciliter are acceptable, although practitioners often call for transfusions when hemoglobin is at 10 grams per deciliter. Of particular importance to EDs, the lower hemoglobin triggers don't always apply to actively bleeding patients. Through a comprehensive blood conservation program, Eastern Maine Medical Center in Bangor, ME, has been able to nearly halve the number of patients who now receive transfusions without negatively impacting patient care. Also, the program has saved the hospital more than $5 million in blood costs.

  12. Acute iatrogenic polycythemia induced by massive red blood cell transfusion during subtotal abdominal colectomy

    David Chiapaikeo

    2015-03-01

    Full Text Available A 46 year old man was transfused ten units of packed red blood cells during subtotal colectomy after intraoperative point-of-care testing values demonstrated hemoglobin values less than seven grams per deciliter (g/dL. A post-operative hemoglobin analyzed in a standard hematologic laboratory revealed a hemoglobin value of 27.8 g/dL. He underwent emergent red blood cell depletion therapy which decreased his hemoglobin to 7.5 g/dL. The physiologic consequences of iatrogenic polycythemia caused by massive transfusion during major abdominal surgery must take into account the fluid shifts that interplay between the osmotic load, viscosity of blood, and postoperative third spacing of fluid. Treatment of acute iatrogenic polycythemia can be effectively accomplished by red blood cell depletion therapy. However, fluid shifts caused by massive transfusion followed by rapid red cell depletion produce a unique physiologic state that is without a well-described algorithm for management.

    1991-01-01

    Treatment with UV-irradiated donor-specific blood transfusion is known to induce specific unresponsiveness in recipient animals and prolong allograft survival. Mixed lymphocyte response in transfused mice was decreased towards spleen cells of the blood donor strain, but was not altered to third-party cells. Sera from treated mice showed significantly lower interleukin-1 (IL-1) activity, which was increased with higher dilutions of sera, indicating the presence of IL-1 inhibitor. Furthermore, sera decreased rIL-1-induced cell proliferation in dose-dependent manner, while the response to rIL-2 neither depended on the concentration of sera, nor differed between non-treated controls and treated mice. These results indicate that UV-irradiated allogeneic blood transfusion could induce an inhibitor, specifically directed to IL-1 activity, which may be involved in the generation of immunological unresponsiveness in treated animals.

    Perioperative blood loss is a major problem in elective orthopedic surgery. Allogeneic transfusion is the standard treatment for perioperative blood loss resulting in low postoperative hemoglobin, but it has a number of well-recognized risks, complications, and costs. Alternatives to allogeneic blood transfusion include preoperative autologous donation and intraoperative salvage with postoperative autotransfusion. Orthopedic surgeons are often unaware of the different pre- and intraoperative possibilities of reducing blood loss and leave the management of coagulation and use of blood products completely to the anesthesiologists. The goal of this review is to compare alternatives to allogeneic blood transfusion from an orthopedic and anesthesia point of view focusing on estimated costs and acceptance by both parties.

In electronic patient records, many diagnostic and procedural codes are registered, but unfortunately, it is usually not specified which one is the reason for transfusion. Therefore, a method is needed to determine the most likely indication for transfusion in an automated way.Study design and methods: An algorithm to identify the most likely transfusion indication was developed and evaluated against a gold standard based on the review of medical records for 234 cases by 2 experts. In a second step, information on misclassification was used to fine-tune the initial algorithm. The adapted algorithm predicts, out of all data available, the most likely indication for transfusion using information on medical specialism, surgical procedures, and diagnosis and procedure dates relative to the transfusion date.Results: The adapted algorithm was able to predict 74.4% of indications in the sample correctly (extrapolated to the full data set 75.5%.

    Background and purpose: Patients with head and neck squamous cell carcinoma (HNSCC) and a low level of haemoglobin (Hb) often have a poor response to radiation which may be related to hypoxia induced radioresistance. The aim of the study was to evaluate the prognostic significance of low Hb level and its modification by transfusion in HNSCC patients treated with radiotherapy. The study was performed as a subrandomization in the DAHANCA 5 trial. Material and methods: Patients were randomized to treatment with the hypoxic radiosensitizer nimorazole or placebo, and in addition, patients with 'low' pre-irradiation Hb values (females < 13 g/dL; males < 14.5 g/dL) were subrandomized to plus or minus transfusion. Transfusion was given with packed red blood cells with the aim to achieve a Hb level in the 'high' value range. Results: A total of 414 patients were included, 243 patients had high Hb levels and 171 patients had low Hb levels. Of the low Hb patients, 82 were randomized to receive transfusion and 89 not to receive transfusion. The treatment arms were well balanced. In the majority of patients, transfusion resulted in increased Hb levels although this tended to decline throughout treatment. Patients with high Hb levels had a significantly better probability of locoregional control, disease-specific survival and overall survival compared to 'low Hb no transfusion' patients. In the low Hb group, transfusion did not improve the outcome in locoregional control, disease-specific survival or overall survival. In multivariate analyses, T and N classifications were significant for all outcome measures, whereas there was no significant influence of transfusion or Hb level on endpoints. Conclusion: The univariate prognostic significance of high Hb level was demonstrated in patients with HNSCC treated with radiotherapy; however, transfusion prior to and during treatment did not improve the outcome in patients with low Hb values.

Early optimal blood transfusion is essential to sustain organ perfusion and oxygenation. There are many variables to consider when establishing an MTP, and studies have prospectively evaluated different scenarios and patient populations to establish the best practices to attain improved patient outcomes. The establishment and utilization of an optimal MTP is challenging given the ever-changing patient status during resuscitation efforts. Much of the MTP literature comes from the trauma population, due to the fact that massive hemorrhage is the leading cause of preventable trauma-related death. As we come to further understand the positive and negative clinical impacts of transfusion-related factors, massive transfusion practice can be further refined. This article will first discuss specific MTPs targeting different patient populations and current relevant international guidelines. Then, we will examine a wide selection of therapeutic products to support MTPs, including newly available products and the most suitable of the traditional products. Lastly, we will discuss the best design for an MTP, including ratio-based MTPs and MTPs based on the use of point-of-care coagulation diagnostic tools.

    Intraoperative cell salvage (CS) of shed blood during emergency surgical procedures provides an effective and cost-efficient resuscitation alternative to allogeneic blood transfusion, which is associated with increased morbidity and mortality in trauma patients. Retrospective matched cohort study. Level I trauma center. All adult trauma patients who underwent an emergency operation and received CS as part of their intraoperative resuscitation. The CS group was matched to a no-CS group for age, sex, Injury Severity Score, mechanism of injury, and operation performed. Amount and cost of allogeneic transfusion of packed red blood cells and plasma. The 47 patients in the CS group were similar to the 47 in the no-CS group for all matched variables. Patients in the CS group received an average of 819 mL of autologous CS blood. The CS group received fewer intraoperative (2 vs 4 U; P = .002) and total (4 vs 8 U; P blood cells. The CS group also received fewer total units of plasma (3 vs 5 U; P = .03). The cost of blood product transfusion (including the total cost of CS) was less in the CS group ($1616 vs $2584 per patient; P = .004). Intraoperative CS provides an effective and cost-efficient resuscitation strategy as an alternative to allogeneic blood transfusion in trauma patients undergoing emergency operative procedures.

    Background Little data are available on bacterial contamination (BC) of platelet units or acute transfusion reactions to platelet transfusions (PT) in sub-Saharan Africa (SSA). Methods This prospective observational study evaluated the rate of BC of whole blood derived platelet units (WB-PU), the utility of performing Gram stains (GS) to prevent septic reactions, characteristics of patients receiving PT and the rate of acute reactions associated with PT at the Uganda Cancer Institute in Kampala, Uganda. An aliquot of each WB-PU studied was taken to perform GS and culture using the Bactec™ 9120 instrument. Study participants were monitored for reactions. Results 337 WB-PU were evaluated for BC, of which 323 units were transfused in 151 transfusion episodes to 50 patients. The frequency of BC ranged from 0.3%–2.1% (according to criteria used to define BC). The GS had high specificity (99.1%), but low sensitivity to detect units with BC. The median platelet count prior to PT was 10,900 (IQR 6,000–18,900) cells/μL. 78% of PT were given to patients with no bleeding. Acute reactions occurred in 11 transfusion episodes, involving 13 WB-PU, for a rate of 7.3% (95%CI=3.7–12.7%) per transfusion episode. All recipients of units with positive bacterial cultures were receiving antibiotics at the time of transfusion; none experienced a reaction. Conclusions The rate of BC observed in this study is lower than previously reported in SSA, but still remains a safety issue. As GS appears to be an ineffective screening tool, alternate methods should be explored to prevent transfusing bacterially-contaminated platelets in SSA. PMID:27079627

  5. Therapeutic modalities of twin to twin transfusion syndrome

    Full Text Available Twin to twin transfusion syndrome (TTTTS accounts for approximately 10% of monochorionic twin pregnancies and, if left untreated, is associated with high morbidity and mortality rate. A net transfusion of blood flow from one fetus (donor twin to the other (recipient twin via placental vascular anastomoses has been supposed as the major etiology of TTTTS. The donor twin becomes hypovolemic and oliguria, oligohydramnios, and a variable degree of growth restriction develop, whereas the recipient twin manifests polyuria, polyhydramnios, and hydrops in response to hypervolemia. TTTTS can be treated by either serial amniocentesis or selective fetoscopic laser coagulation of the communicating vessels. The rationale for removal of large volumes of amniotic fluid is to prevent preterm delivery secondary to polyhydramnios and to improve fetal circulation by reducing pressure on the chorionic plate. On the other hand, the goal of laser therapy is to occlude vascular anastomoses, thereby interrupting intertwin blood exchange. Although laser treatment is associated with increased survival rate and reduced neurologic complications, compared with amnioreduction, it requires highly specialized centers, whereas serial amniocentesis has the advantage of being performed worldwide. Therefore, the optimal treatment for pregnancies complicated with TTTTS is still controversial.

    To assess the accuracy of published formulas used to guide packed red blood cell (pRBC) transfusions in anemic dogs and to compare the predicted rise in packed cell volume (PCV) to the actual post-transfusion rise in PCV. Prospective observational study from April 2009 through July 2009. A small animal emergency and specialty hospital. Thirty-one anemic client-owned dogs that received pRBC transfusions for treatment of anemia. None Four formulas were evaluated to determine their predictive ability with respect to rise in PCV following transfusion with pRBC. Post-transfusion rise in PCV were compared to calculated rise in PCV using 4 different formulas. Bias and limits of agreement were investigated using Bland-Altman analyses. Accuracy of existing formulas to predict rise in PCV following transfusion varied significantly. Formula 1 (volume to be transfused [VT] [mL] = 1 mL × % PCV rise × kg body weight [BW]) overestimated the expected rise in PCV (mean difference, 6.30), while formula 2 (VT [mL] = 2 mL ×% PCV rise × kg BW) underestimated the rise in PCV (mean difference, -3.01). Formula 3 (VT [mL] = 90 mL × kg BW × [(desired PCV - Patient PCV)/PCV of donor blood]) and formula 4 (VT [mL] = 1.5 mL ×% PCV rise × kg BW) performed well (mean difference 0.23 and 0.09, respectively) in predicting rise in PCV following pRBC transfusion. Agreement between 2 formulas, "VT (mL) = kg BW × blood volume (90 mL) × [(desired PCV - recipient PCV)/Donor PCV]" and "VT (mL) = 1.5 ×desired rise in PCV × kg BW," was found when they were compared to the actual rise in PCV following pRBC transfusion in anemic dogs. Further research is warranted to determine whether these formulas perform similarly well for other species. © Veterinary Emergency and Critical Care Society 2012.

    Full Text Available Backgroundp: Very low birth weight infants ( <1500 g frequently require blood transfusions because of repeated blood sampling accompanied by anemia of prematurity. Methods: In an attempt to identify the effect of human recombinant erythropoietin to decrease the requirement for blood transfusions, erythropoietin was administered to 24 pre term infants less than 1500 g prospectively from September 1999 till December2000. Data about the characteristics of the population, the severity of diseases, and treatment with erythropoietin, clinical diagnosis, initial and subsequent hemoglobin, volume of blood loss, and the number of blood transfusions were recorded. These results were compared with data from the recorded information of 49 infants who did not receive erythropoietin during those past 2 years. There were no differences between the 2 groups with regard to the gestational age, birth weight, clinical diagnosis, severity of the illness, primary causes of admission, and initial hematologic parameters such as hemoglobin, hematocrit and reticulocytes. Erythropoietin was administered in a dose of 200 ill/kg three times weekly for 6-8 weeks accompanied with iron supplement 6 mg/ kg/day. Transfusions were administered according to protocol. Results: There was no significant difference between the number of blood transfusion among these 2 groups (p= 0.07. However, transfusions in the erythropoietin treated group were fewer in comparison to the other group (1.9 +1-1.6 to 3.2 +/-1.1. No difference was observed between final hemoglobin and hematocrit levels among the two groups (10.3 +1- 0.9 vs. 10.4 +1- 0.7 and 33.7 +1- 2.3 vs. 32.2 +1- 2.2. Conclusion: Very low birth weight infants receive frequent blood transfusions but a reduction in transfusion requirements was not apparent after administration of erythropoietin and iron in preterm infants in this study. However, the lack of impact on transfusion requirements fails to support routine use of

    Early recognition and treatment of trauma patients requiring massive transfusion (MT) has been shown to reduce mortality. While many risk factors predicting MT have been demonstrated, there is no universally accepted method or algorithm to identify these patients. We hypothesised that even among experienced trauma surgeons, the clinical gestalt of identifying patients who will require MT is unreliable. Transfusion and mortality outcomes after trauma were observed at 10 U.S. Level-1 trauma centres in patients who survived ≥ 30 min after admission and received ≥ 1 unit of RBC within 6h of arrival. Subjects who received ≥ 10 units within 24h of admission were classified as MT patients. Trauma surgeons were asked the clinical gestalt question "Is the patient likely to be massively transfused?" 10 min after the patients arrival. The performance of clinical gestalt to predict MT was assessed using chi-square tests and ROC analysis to compare gestalt to previously described scoring systems. Of the 1245 patients enrolled, 966 met inclusion criteria and 221 (23%) patients received MT. 415 (43%) were predicted to have a MT and 551(57%) were predicted to not have MT. Patients predicted to have MT were younger, more often sustained penetrating trauma, had higher ISS scores, higher heart rates, and lower systolic blood pressures (all pGestalt sensitivity was 65.6% and specificity was 63.8%. PPV and NPV were 34.9% and 86.2% respectively. Data from this large multicenter trial demonstrates that predicting the need for MT continues to be a challenge. Because of the increased mortality associated with delayed therapy, a more reliable algorithm is needed to identify and treat these severely injured patients earlier. Copyright © 2015 Elsevier Ltd.

    Background Blood transfusions carry the risk of transmitting blood-borne infections. In contrast to the situation in the developed world, there is a limited number of studies examining this problem in sub-Saharan Africa. In this study we aimed to calculate the risks of acquiring human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infection from units of blood issued by the Gabonese Blood Transfusion Centre between 2009 and 2011. Materials and methods All the donations were tested for infectious diseases and the seroconversion incidence rates of HIV, HBV and HCV were calculated. The residual risk of transfusion-associated transmission for each virus was calculated by multiplying the seroconversion rates by the window period expressed in fractions of a year. Results The risks of becoming infected with HIV, HCV, and HBV in subjects receiving units of blood from the Gabonese Blood Transfusion Centre were 64.7, 207.94 and 534.53 per million donations, respectively. Conclusions This study, which is the first to quantify the true risks of transfusion-transmitted infections in Gabon, reveals and confirms the need to reinforce preventative and screening strategies to improve transfusion safety in sub-Saharan Africa.

    One of the most frequent error in transfusion medicine is the failure in verifying the patient's identity prior to transfusion. This paper describes the design and development of a Mobile Application (MA) for transfusion medicine. The app uses barcode and QR reading technology for the verification of the patient's identity and the administration of blood components when making a blood transfusion. Physicians, developers, technicians of transfusion medicine and a User Centered Design team participated in the design. The inclusion of end users was fundamental to get full representativeness of their workflow. The project was based on agile methodologies of project management and software development.

    In this study significantly prolonged canine renal allograft survival has been demonstrated after transfusion of 100 ml of third-party whole blood given peroperatively. Peroperative transfusions of third-party leukocyte-free blood or pure lymphocyte cell suspensions did not influence graft survival. Furthermore, no improvement in graft survival has been found after a peroperative transfusion of irradiated whole blood (2500 rad). These data suggest that delayed graft rejection after blood transfusions can only be expected after the administration of whole blood. The role of competent lymphocytes in whole blood is questionable, since a transfusion or irradiated whole blood in combination with nonirradiated lymphocytes did not lead to prolonged graft survival. Immunosuppression of the recipient directly after transfusion seems to be essential to induce the beneficial effect of blood transfusions. This has been demonstrated for a transfusion of whole blood 14 days before transplantation. A single transfusion of 100 ml of whole blood 14 days before transplantation could effectively prolong graft survival if immunosuppression with azathioprine and prednisone was started on the day of transfusion. No improvement in graft survival has been found with such a transfusion if preoperative immunosuppression has been omitted

    Thalassemia intermedia is a type of anemia which has several treatments modalities. We aimed to study the cost effectiveness of two treatments, including blood transfusion and hydroxyurea, in patients with beta-thalassemia intermedia in south of Iran referred to a referral center affiliated to Iran, Shiraz University of Medical Sciences in 2015. This was a cost-effectiveness study which was conducted on 122 patients with beta-thalassemia intermedia. The indicator of effectiveness in this study was the reduction of growth disorder (normal BMI). Data analysis was done using SPSS 21, Excel 2010 and Treeage 2011. Finally, the one-way sensitivity analysis was performed to determine the robustness of the results. The average annual costs of blood transfusion and the use of hydroxyurea in 2015 were 20733.27 purchasing power parity (PPP)$ and 7040.29 PPP$, respectively. The effectiveness of blood transfusion was57.4% while in hydroxyurea group was 60.7%. The results showed that the cost effectiveness of using hydroxyurea was more than that of blood transfusion. Therefore, it is recommended that the use of hydroxyurea in the treatment of patients with beta-thalassemia intermedia would become the first priority, and more basic and supplementary insurance coverage for treating such patients using hydroxyurea should be considered.

    Background Concerns regarding the safety of transfused blood have led to the development of a range of interventions to minimise blood loss during major surgery. Anti-fibrinolytic drugs are widely used, particularly in cardiac surgery, and previous reviews have found them to be effective in reducing blood loss, the need for transfusion, and the need for re-operation due to continued or recurrent bleeding. In the last few years questions have been raised regarding the comparative performance of the drugs. The safety of the most popular agent, aprotinin, has been challenged, and it was withdrawn from world markets in May 2008 because of concerns that it increased the risk of cardiovascular complications and death. Objectives To assess the comparative effects of the anti-fibrinolytic drugs aprotinin, tranexamic acid (TXA), and epsilon aminocaproic acid (EACA) on blood loss during surgery, the need for red blood cell (RBC) transfusion, and adverse events, particularly vascular occlusion, renal dysfunction, and death. Search methods We searched: the Cochrane Injuries Group’s Specialised Register (July 2010), Cochrane Central Register of Controlled Trials (The Cochrane Library 2010, Issue 3), MEDLINE (Ovid SP) 1950 to July 2010, EMBASE (Ovid SP) 1980 to July 2010. References in identified trials and review articles were checked and trial authors were contacted to identify any additional studies. The searches were last updated in July 2010. Selection criteria Randomised controlled trials (RCTs) of anti-fibrinolytic drugs in adults scheduled for non-urgent surgery. Eligible trials compared anti-fibrinolytic drugs with placebo (or no treatment), or with each other. Data collection and analysis Two authors independently assessed trial quality and extracted data. This version of the review includes a sensitivity analysis excluding trials authored by Prof. Joachim Boldt. Main results This review summarises data from 252 RCTs that recruited over 25,000 participants. Data from

    Massive traumatic haemorrhage is aggravated through the development of trauma-induced coagulopathy, which is managed by plasma transfusion and/or fibrinogen concentrate administration. It is yet unclear whether these treatments are equally potent in ensuring adequate haemostasis, and whether additional factor XIII (FXIII) administration provides further benefits. In this study, we compared ROTEM whole blood coagulation profiles after experimental massive transfusion with different transfusion regimens in an in vitro model of dilution- and transfusion-related coagulopathy. Healthy donor blood was mixed 1 + 1 with six different transfusion regimens. Each regimen contained RBC, platelet concentrate, and either fresh frozen plasma (FFP) or Ringer's acetate (RA). The regimens were further augmented through addition of a low- or medium-dose fibrinogen concentrate and FXIII. Transfusion with FFP alone was insufficient to maintain tissue-factor activated clot strength, coincidental with a deficiency in fibrin-based clot strength. Fibrinogen concentrate conserved, but did not improve coagulation kinetics and overall clot strength. Only combination therapy with FFP and low-dose fibrinogen concentrate improved both coagulation kinetics and fibrin-based clot strength. Administration of FXIII did not result in an improvement of clot strength. In conclusion, combination therapy with both FFP and low-dose fibrinogen concentrate improved clotting time and produced firm clots, representing a possible preferred first-line regimen to manage trauma-induced coagulopathy when RBC and platelets are also transfused. Further research is required to identify optimal first-line transfusion fluids for massive traumatic haemorrhage.

    The partial exchange transfusions necessary for management of some sickle-cell complications raise the issue of effectiveness in the context of limited resources and inadequate blood safety. This study evaluated the effectiveness, safety, and cost of partial exchange transfusions in 39 patients with sickle-cell anemia in Lubumbashi, looking at the patients' age and gender and the tolerability and direct cost of the transfusions. Excel and SPSS 18 were used for data entry and analysis. Chi2 and Fisher exact tests were used for comparisons. A P-value ≤ 5% was considered statistically significant. The average age of patients was 8.6 ± 6.4 years, and the majority were girls. The most frequent indications were stroke, severe infections, severe vasooclusive crises, and acute chest syndrome. Partial exchange transfusions were effective in improving hemoglobin and hematocrit as well as the percentage of HbS. No acute accident was observed during any partial exchange transfusion; one anti-Kell alloimmunization and 2 cases of iron overload were observed. The annual cost of partial exchange transfusions per patient requiring (and able to afford) regular treatment was US $ 3,345 without iron chelation and more than US $ 5000 with chelation. Partial exchange transfusions are effective and tolerated, but financially inaccessible to the majority of our sickle cell patients. Thus, an assessment is needed of the economic burden of sickle cell complications that require partial exchange transfusions in the context of countries with limited financial resources.

    Morbidly obese patients are at increased risk for venous thromboembolism (VTE) after bariatric surgery. Perioperative chemoprophylaxis is used routinely with bariatric surgery to decrease the risk of VTE. When bleeding occurs, routine chemoprophylaxis is often withheld due to concerns about inciting another bleeding event. We sought to evaluate the relationship between perioperative bleeding and postoperative VTE in bariatric surgery. The American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) dataset between 2012 and 2014 was queried to identify patients who underwent bariatric surgery. Gastric bypass (n = 28,145), sleeve gastrectomy (n = 30,080), bariatric revision (n = 324), and biliopancreatic diversion procedures (n = 492) were included. Univariate and multivariate regressions were used to determine perioperative factors predictive of postoperative VTE within 30 days in patients who experience a bleeding complication necessitating transfusion. The rate of bleeding necessitating transfusion was 1.3%. Bleeding was significantly more likely to occur in gastric bypass compared to sleeve gastrectomy (1.6 vs. 1.0%) (p surgeries, increased age, length of stay, operative time, and comorbidities including hypertension, dyspnea with moderate exertion, partially dependent functional status, bleeding disorder, transfusion prior to surgery, ASA class III/IV, and metabolic syndrome increased the perioperative bleeding risk (p Bariatric surgery patients who receive postoperative blood transfusion are at a significantly increased risk for VTE. The etiology of VTE in those who are transfused is likely multifactorial and possibly related to withholding chemoprophylaxis and the potential of a hypercoagulable state induced by the transfusion. In those who bleed, consideration should be given to reinitiating chemoprophylaxis when safe, extending treatment after discharge, and screening ultrasound.

    Homozygous, sickle-cell disease (SCD) is responsible for acute complication, especially anaemic crisis and special situation such as acute chest syndrome, stroke and acute priapism. Pregnancy sickle-cell disease presents high risk for the mother and the fetus. In these indications, blood transfusion is the main therapy aiming to reduce anaemia in order to restore hemoglobin's rate or to increase normal Hb proportion. This study aims to assess the short-term efficiency of the red cell transfusion in SCD homozygous form. One hundred and twelve homozygous sickle-cell patients were enrolled in this prospective study: 59 females and 53 males, median age is 21,8 years (extremes: 2 and 45 years). These patients are mostly with very low income. Two groups of patients are included in this study. In the first group, patients present acute anemia crisis caused by infections disease (malaria, bacterial infections). In the second group (20 cases), SCD patients have particularly situations: pregnancy (10 cases); stroke (six cases); cardiac failure (two cases) and priapism (two cases). Transfusion treatment in first group is simple regimen. Transfusion of EC increased median Hb level at 2,9 g/dl (extremes: 1,1 and 4,7). In the second group of patients, 16 cases were transfused by manual partial exchange (1-3) and four patients received simple regimen of transfusion. Median Hb level was 3,1g/dl (extremes: 2,4-4,9 g/dl). HbS percentage reduction was after PTE between -30 and -66,8% (median: -52,6%). According to our diagnostic possibilities (blood serologic test), we have not found any contamination by HIV, HBV and HCV (virus).

    Rotation thromboelastometry (TEM) has been proposed as a convenient alternative to standard coagulation tests in guiding the treatment of coagulopathy during orthotopic liver transplantation (OLT). This study was aimed at assessing the value of TEM in monitoring blood coagulation and guide transfusion support in OLT. Standard coagulation and TEM (EXTEM and FIBTEM) tests were performed at four preestablished intraoperative time points in 236 OLTs and prospectively recorded in a dedicated database together with the main operative and transfusion data. Transfusion thresholds were based on standard coagulation tests. Spearman's rank correlation (ρ), linear regression, and receiver operating characteristic curves were used when appropriate. EXTEM maximum clot firmness (MCF(EXTEM)) was the TEM variable that best correlated with the platelet (PLT) and fibrinogen levels (ρ = 0.62 and ρ = 0.69, respectively). MCF(FIBTEM) correlated with fibrinogen level (ρ = 0.70). EXTEM clot amplitude at 10 minutes (A10(EXTEM)) was a good linear predictor of MCF(EXTEM) (R(2) =0.93). The cutoff values that best predicted the transfusion threshold for PLTs and fibrinogen were A10(EXTEM) = 35 mm and A10(FIBTEM) = 8 mm. At these values, the negative and positive predictive accuracies of TEM to predict the transfusion thresholds were 95 and 27%, respectively. A10(EXTEM) is an adequate TEM variable to guide therapeutic decisions during OLT. Patients with A10(EXTEM) of greater than 35 mm are unlikely to bleed because of coagulation deficiencies, but using A10(EXTEM) of not more than 35 mm as the sole transfusion criterion can lead to unnecessary utilization of PLTs and fibrinogen-rich products. © 2012 American Association of Blood Banks.

    The use of chimeric antigen receptor (CAR)-T cell therapy for the treatment of hematologic malignancies has generated significant excitement over the last several years. From a transfusion medicine perspective, the implementation of CAR-T therapy as a potential mainstay treatment for not only hematologic but also solid-organ malignancies represents a significant opportunity for growth and expansion. In this review, we will describe the rationale for the development of genetically redirected T cells as a cancer therapeutic, the different elements that are required to engineer these cells, as well as an overview of the process by which patient cells are harvested and processed to create and subsequently validate CAR-T cells. Finally, we will briefly describe some of the toxicities and clinical efficacy of CAR-T cells in the setting of patients with advanced malignancy. Copyright © 2016 Elsevier Inc. All rights reserved.

    One of the most serious risks of blood transfusions is an error in ABO blood group compatibility, which can cause a haemolytic transfusion reaction and, in the most severe cases, the death of the patient. The frequency and type of errors observed suggest that these are inevitable, in that mistakes are inherent to human nature, unless significant changes, including the use of computerised instruments, are made to procedures. In order to identify patients who are candidates for the transfusion of blood components and to guarantee the traceability of the transfusion, the Securblood system (BBS srl) was introduced. This system records the various stages of the transfusion process, the health care workers involved and any immediate transfusion reactions. The patients and staff are identified by fingerprinting or a bar code. The system was implemented within Ragusa hospital in 16 operative units (ordinary wards, day hospital, operating theatres). In the period from August 2007 to July 2008, 7282 blood components were transfused within the hospital, of which 5606 (77%) using the Securblood system. Overall, 1777 patients were transfused. In this year of experience, no transfusion errors were recorded and each blood component was transfused to the right patient. We recorded 33 blocks of the terminals (involving 0.6% of the transfused blood components) which required the intervention of staff from the Service of Immunohaematology and Transfusion Medicine (SIMT). Most of the blocks were due to procedural errors. The Securblood system guarantees complete traceability of the transfusion process outside the SIMT and eliminates the possibility of mistaken identification of patients or blood components. The use of fingerprinting to identify health care staff (nurses and doctors) and patients obliges the staff to carry out the identification procedures directly in the presence of the patient and guarantees the presence of the doctor at the start of the transfusion.

    Full Text Available Platelet transfusions have contributed to the revolutionary modern treatment of hypoproliferative thrombocytopenia. Despite the long-term application of platelet transfusion in therapeutics, all aspects of their optimal use (i.e., in cases of ABO and/or Rh (D incompatibility have not been definitively determined yet. We reviewed the available data on transfusion practices and outcome in ABO and RhD incompatibility and platelet refractoriness due to anti-human leukocyte antigen (HLA antibodies. Transfusion of platelets with major ABO-incompatibility is related to reduced posttransfusion platelet (PLT count increments, compared to ABO-identical and minor, but still are equally effective in preventing clinical bleeding. ABO-minor incompatible transfusions pose the risk of an acute hemolytic reaction of the recipient that is not always related to high anti-A, B donor titers. ABO-identical PLT transfusion seems to be the most effective and safest therapeutic strategy. Exclusive ABO-identical platelet transfusion policy could be feasible, but alternative approaches could facilitate platelet inventory management. Transfusion of platelets from RhD positive donors to RhD negative patients is considered to be effective and safe though is associated with low rate of anti-D alloimmunization due to contaminating red blood cells. The prevention of D alloimmunization is recommended only for women of childbearing age. HLA alloimmunization is a major cause of platelet refractoriness. Managing patients with refractoriness with cross-matched or HLA-matched platelets is the current practice although data are still lacking for the efficacy of this practice in terms of clinical outcome. Leukoreduction contributes to the reduction of both HLA and anti-D alloimmunization.

    Blood loss and high rates of transfusion in burn centers remains an area of ongoing concern. Blood use brings the risk of infection, adverse reaction, and immunosuppression. A protocol to reduce blood loss and blood use was implemented. Analysis included 3-year periods before and after institution of the protocol. All patients were transfused for a hemoglobin below 8.0 gm/dL. Operations per admission did not change during the two time periods (0.78 in each). Overall units transfused per operation decreased from 1.56+/-0.06 to 1.25+/-0.14 units after instituting the protocol (pburns of less than 20% surface area, declining from 386 to 46 units after protocol institution, from 0.37 to 0.04 units per admission, and from 0.79 to 0.08 units per operation in this group of smallest burns. There was no change noted in the larger burns. This study suggests that a defined protocol of hemostasis, technique, and transfusion trigger should be implemented in the process of burn excision and grafting. This will help especially those patients with the smallest burns, essentially eliminating transfusion need in that group.

    Despite being prohibited by the World Anti-Doping Agency, blood doping through erythropoietin injection or blood transfusion is frequently used by athletes to increase oxygen delivery to muscles and enhance performance. In contrast with allogeneic blood transfusion and erythropoietic stimulants, there is presently no direct method of detection for autologous blood transfusion (ABT) doping. Blood reinfusion is currently monitored with individual follow-up of hematological variables via the athlete biological passport, which requires further improvement. Microdosage is undetectable, and suspicious profiles in athletes are often attributed to exposure to altitude, heat stress, or illness. Additional indirect biomarkers may increase the sensitivity and specificity of the longitudinal approach. The emergence of "-omics" strategies provides new opportunities to discover biomarkers for the indirect detection of ABT. With the development of direct quantitative methods, transcriptomics based on microRNA or messenger RNA expression is a promising approach. Because blood donation and blood reinfusion alter iron metabolism, quantification of proteins involved in metal metabolism, such as hepcidin, may be applied in an "ironomics" strategy to improve the detection of ABT. As red blood cell (RBC) storage triggers changes in membrane proteins, proteomic methods have the potential to identify the presence of stored RBCs in blood. Alternatively, urine matrix can be used for the quantification of the plasticizer di(2-ethyhexyl)phthalate and its metabolites that originate from blood storage bags, suggesting recent blood transfusion, and have an important degree of sensitivity and specificity. This review proposes that various indirect biomarkers should be applied in combination with mathematical approaches for longitudinal monitoring aimed at improving ABT detection.

    This editorial discusses the situation of administering blood to patients prior to radiotherapy in an attempt to increase tissue/tumor oxygen tension. The author believes that since the rate at which tumor cells consume oxygen is highly variable, the aim of achieving high cellular oxygen tension may be met better by maintaining a high blood perfusion rate. Blood volume can be maintained without relying on transfusion, and safer alternatives are available

It has been established that the hemorrhagic syndrome is the main one deterimining the unity of pathogenesis and clinical picture of the hemotransfusional complication. Phase character of the changes in the homeostasis system during the transfusion of incompatible blood was noted. The express diagnosis of the disorders and a scheme of the sequence of administration of hemostatic drugs are proposed. Mortality among such patients was reduced.

    In this study significantly prolonged canine renal allograft survival has been demonstrated after transfusion of 100 ml of third-party whole blood given peroperatively. Peroperative transfusions of third-party leukocyte-free blood or pure lymphocyte cell suspensions did not influence graft survival. Futhermore, no improvement in graft survival has been found after a peroperative transfuson of irradiated whole blood (2500 rad). These data suggest that delayed graft rejection after blood transfusions can only be expected after the administration of whole blood. The role of competent lymphocytes in whole blood is questionable, since a transfusion of irradiated whole blood in combination with nonirradiated lymphocytes did not lead to prolonged graft survival. Immunosuppression of the recipient directly after transfusion seems to be essential to induce the beneficial effect of blood transfusions. This has been demonstrated for a transfusion of whole blood 14 days before transplantation. A single transfusion of 100 ml of whole blood 14 days before transplantation could effectively prolong graft survival if immunosuppression with azathioprine and prednisone was started on the day of transfusion. No improvement in graft survival has been found with such a transfusion if preoperative immunosuppression has been omitted

    Thrombocytopenia is a hallmark of dengue infection, and bleeding is a dreaded complication of dengue fever. Prophylactic platelet transfusion has been used to prevent bleeding in the management of dengue fever, although the evidence for its benefit is lacking. In adult dengue patients with platelet count Tan Tock Seng Hospital from January 2005 to December 2008. Baseline characteristics and clinical outcomes were compared between the non-transfused vs. transfused groups. Outcomes studied were clinical bleeding, platelet increment, hospital length of stay, intensive care unit admission and death. Of the 788 patients included, 486 received prophylactic platelet transfusion. There was no significant difference in the presence of clinical bleeding in the two groups (18.2% in non-transfused group vs. 23.5% in transfused group; P = 0.08). Patients in the transfused group took a median of 1 day longer than the non-transfused group to increase their platelet count to 50,000/mm3 or more (3 days vs. 2 days, P hospital stay in the non-transfused group was 5 days vs. 6 days in the transfused group (P50,000/mm3 and increasing length of hospitalization.

    Blood conservation using autologous platelet-rich plasma (aPRP), a technique of whole blood harvest that separates red blood cells from plasma and platelets before cardiopulmonary bypass with retransfusion of the preserved platelets after completion of cardiopulmonary bypass, has not been studied extensively. We sought to prospectively determine whether aPRP reduces blood transfusions during ascending and transverse aortic arch repair. We randomly assigned 80 patients undergoing elective ascending and transverse aortic arch repair using deep hypothermic circulatory arrest to receive either aPRP (n = 38) or no aPRP (n = 42). Volume of aPRP retransfused was 726 ± 124 mL. The primary end point was transfusion amount. Secondary end points were death, stroke, renal failure, pulmonary failure, and transfusion costs. Perioperative transfusion rate was defined as blood transfusions given during surgery and up to 72 hours afterward. The surgeon and intensivist were blinded to the treatment arm. Because an anesthesiologist initiated the protocol, the surgeon was not aware of aPRP collection, as this occurred only after the sterile drape was in place. In addition, because cell salvage was performed on all cases, differentiation in perfusionist activities (during spinning of aPRP) was not evident. Platelet, fresh frozen plasma, and cryoprecipitate intraoperative transfusions were performed only after heparin was reversed and the patient was judged as coagulopathic on the basis of associated criteria: cryoprecipitate transfusion for fibrinogen level less than 150 μg/dL, platelet transfusion for platelet count less than 80,000, and fresh frozen plasma when thromboelastogram test was suggestive or a partial thromboplastin time was greater than 55 seconds, and prothrombin time was greater than 1.6 seconds. Early mortality, stroke, and respiratory complications were similar between groups. Only acute renal failure was reduced in the aPRP group, 7% versus 0% (p platelets by 56

Classification of AIHA is based on the optimal auto-RBC antibody reactivity temperatures and includes warm, cold-reactive, mixed AIHA, and drug-induced AIHA subtypes. AIHA is a rare disease, and recommendations for transfusion are based mainly on results from retrospective data and relatively small cohort studies, including heterogeneous patient samples or single case reports. In this article, we will review the challenges and solutions to safely transfuse AIHA patients. We will reflect on the indication for transfusion in AIHA and the difficulty in the accomplishment of immunohematological procedures for the selection of the safest and most compatible RBC units.

    To compare the incidence of repeated red blood cell (RBC) transfusion in anemic gynecologic cancer patients receiving platinum-based chemotherapy comparing intravenous and oral iron. Forty-four anemic gynecologic cancer patients (hemoglobin level below 10 mg/dl) who required RBC transfusion were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. Study group received 200 mg of intravenous iron sucrose and control group received oral ferrous sulphate 600 mg/day. RBC transfusion requirement in the consecutive cycle of chemotherapy was the primary outcome. Quality of life was evaluated by validated Thai version of the Functional Assessment of Cancer Therapy-Anemia (FACT-An). In a total of the 44 patients, there were 22 patients in each group. Five patients (22.7%) in the study group and 14 patients (63.6%) in the control group required RBC transfusion in consecutive cycle of chemotherapy (p=0.01). No significant difference in baseline hemoglobin and hematocrit levels was demonstrated in both groups. Significantly higher mean hemoglobin and hematocrit levels after treatment were reported in the study group (10.0+/-0.8 g/dl and 30.5+/-2.4%) than the control group (9.5+/-0.9 g/dl and 28.4+/-2.7%). No significant change of total FACT-An scores was noted between before and after treatment in both groups. No serious adverse events were reported and there was no significant difference among adverse events between both groups. Intravenous iron is an alternative treatment for anemic gynecologic cancer patients receiving platinum-based chemotherapy and reduces the incidence of RBC transfusion without serious adverse events.

    Class I evidence supporting a threshold for transfusion in the cardiac surgical setting is scarce. We randomly allocated patients to a transfusion hematocrit trigger of 24% versus 28% to compare morbidity, mortality, and resource use. From March 2007 to August 2014, two centers randomly assigned 722 adults undergoing coronary artery bypass graft surgery or valve procedures to a 24% hematocrit trigger (n = 363, low group) or 28% trigger (n = 354, high group). One unit of red blood cells was transfused if the hematocrit fell below the designated threshold. The primary endpoint was a composite of postoperative morbidities and mortality. Treatment effect was primarily assessed using an average relative effect generalized estimating equation model. At the second planned interim analysis, the a priori futility boundary was crossed, and the study was stopped. There was no detected treatment effect on the composite outcome (average relative effect odds ratio, low versus high, 0.86, 95% confidence interval: 0.29 to 2.54, p = 0.71). However, the low group received fewer red blood cell transfusions than the high group (54% versus 75%, p < 0.001), mostly administered in the operating room (low group, 112 [31%]; high group, 208 [59%]), followed by intensive care unit (low, 105 [31%]; high, 115 [34%]) and floor (low, 41 [12%]; high, 42 [13%]). The low group was exposed to lower hematocrits: median before transfusion, 22% (Q1 = 21%, Q3 = 23%) versus 24% (Q1 = 22%, Q3 = 25%). Negative exposures differed between treatment groups, with lower hematocrit in the 24% trigger group and more red blood cells used in the 28% group, but adverse outcomes did not differ. Because red blood cell use was less with a 24% trigger without adverse effects, our randomized trial results support aggressive blood conservation efforts in cardiac surgery.

    Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in thrombocytopenic patients with bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004 and updated in 2012 that addressed four separate questions: therapeutic-only versus prophylactic platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. We have now split this review into four smaller reviews looking at these questions individually; this review is the first part of the original review. Objectives To determine whether a therapeutic-only platelet transfusion policy (platelet transfusions given when patient bleeds) is as effective and safe as a prophylactic platelet transfusion policy (platelet transfusions given to prevent bleeding, usually when the platelet count falls below a given trigger level) in patients with haematological disorders undergoing myelosuppressive chemotherapy or stem cell transplantation. Search methods We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (Cochrane Library 2015, Issue 6), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950) and ongoing trial databases to 23 July 2015. Selection criteria RCTs involving transfusions of platelet concentrates prepared either from individual units of whole blood or by apheresis, and given to prevent or treat bleeding in patients with malignant haematological disorders receiving myelosuppressive chemotherapy or undergoing HSCT. Data collection and analysis We used standard methodological procedures

    Neurosurgical procedures can be complicated by significant blood losses that have the potential to decrease tissue perfusion to critical brain tissue. Red blood cell transfusion is used in a variety of capacities both inside, and outside, of the operating room to prevent untoward neurologic damage. However, evidence-based guidelines concerning thresholds and indications for transfusion in neurosurgery remain limited. Consequently, transfusion practices in neurosurgical patients are highly variable and based on institutional experiences. Recently, a paradigm shift has occurred in neurocritical intensive care units, whereby restrictive transfusion is increasingly favored over liberal transfusion but the ideal strategy remains in clinical equipoise. The authors of this study perform a systematic review of the literature with the objective of capturing the changing landscape of blood transfusion indications in neurosurgical patients.

    The risks and costs of transfusion are a great concern in the area of pediatric spine surgery, because it is a blood-intensive procedure with a high risk for transfusion. Therefore, determining the predictors of transfusion in this patient population is an important first step and has the potential to improve upon the current approaches to reducing transfusion rates. In this study, we reveal several predictors of transfusion in a pediatric patient population undergoing spine surgery. In turn, we present a general rule of thumb ("rule of two's") for gauging transfusion risk, thus enhancing the surgeon's approach to avoiding transfusion in certain clinical scenarios. This study was conducted to determine the main factors of transfusion in a population of pediatric patients undergoing scoliosis surgery. The goal was to present an algorithm for quantifying the true risk of transfusion for various patient groups that would highlight patients "at high risk" for transfusion. This is especially important in light of the various risks associated with undergoing a transfusion, as well as the costs involved in maintaining and disposing of exogenous blood materials. This is a retrospective review of a group of children who underwent scoliosis surgery between 1988 and 1995 at an academic institution. A total of 290 patients were analyzed in this study, of which 63 were transfused and 227 were not. No outcomes measures were used in this study. A retrospective review of 290 patients presenting to our institution for scoliosis surgery was conducted, with a focus on socioclinical data related to transfusion risk. Univariate analysis and logistic regression were used to quantify the determinants of transfusion risk. Univariate analysis identified many factors that were associated with the risk of transfusion. However, it is clear that several of these factors are dependent on each other, obscuring the true issues driving transfusion need. We used multivariate analysis to control for

    Full Text Available Objectives Bleeding is the most common complication of percutaneous nephrolithotomy (PCNL. Injudicious transfusion is frequently performed in current practice, even though it is not always needed. This study aimed to identify the predictive factors of blood loss in the PCNL procedure and evaluate the perioperative transfusion practice.   Methods A prospective study of PCNL was randomly performed by two consultants of endo-urology at our institution. The inclusion criteria were adults with kidney pelvic stones >20 mm or stone in inferior calyx >10 mm or staghorn stone. Those with coagulopathy, under anti-coagulant treatment or open conversion were excluded. A full blood count was taken at baseline and during 12, 24, 36, 72-hours post-operatively. Factors such as stone burden, sex, body surface area, shifting of hematocrit level and amount of blood transfused were analyzed statistically using line regression to identify the predictive factors of total blood loss (TBL.   Results Eighty-five patients were enrolled in this study. Mean TBL was 560.92 ± 428.43 mL for both endo-urology surgeons. Stone burden was the most influential factor for TBL (p=0.037. Our results revealed that TBL (mL = -153.379 + 0.229 × stone burden (mm2 + 0.203 x baseline serum hematocrit (%; thus considerably predicted the need for blood transfusion. A total of 87.1% patients did not receive perioperative transfusion, 3.5% received intra-operative transfusion, 7.1% received post-operative transfusion, 23% had both intra and post-operative transfusion, resulting in a cross-matched transfusion ratio of 7.72. Mean perioperative blood transfused was 356.00 ± 145.88 mL.

    Retrospective cohort study. To identify factors associated with blood transfusion for primary posterior lumbar fusion surgery, and to identify associations between blood transfusion and other postoperative complications. Blood transfusion is a relatively common occurrence for patients undergoing primary posterior lumbar fusion. There is limited information available describing which patients are at increased risk for blood transfusion, and the relationship between blood transfusion and short-term postoperative outcomes is poorly characterized. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing primary posterior lumbar fusion from 2011 to 2013. Multivariate analysis was used to find associations between patient characteristics and blood transfusion, along with associations between blood transfusion and postoperative outcomes. Out of 4223 patients, 704 (16.7%) had a blood transfusion. Age 60 to 69 (relative risk [RR] 1.6), age greater than equal to 70 (RR 1.7), American Society of Anesthesiologists class greater than equal to 3 (RR 1.1), female sex (RR 1.1), pulmonary disease (RR 1.2), preoperative hematocrit less than 36.0 (RR 2.0), operative time greater than equal to 310 minutes (RR 2.9), 2 levels (RR 1.6), and 3 or more levels (RR 2.1) were independently associated with blood transfusion. Interbody fusion (RR 0.9) was associated with decreased rates of blood transfusion. Receiving a blood transfusion was significantly associated with any complication (RR 1.7), sepsis (RR 2.6), return to the operating room (RR 1.7), deep surgical site infection (RR 2.6), and pulmonary embolism (RR 5.1). Blood transfusion was also associated with an increase in postoperative length of stay of 1.4 days (P risk factors for these occurrences were characterized. Strategies to minimize blood loss might be considered in these patients to avoid the associated complications. 3.

    Full Text Available Abstract Background This study measured how myelodysplastic syndrome (MDS patients value transfusion independence (TI, reduced transfusions (RT and transfusion-dependence (TD using health utility assessment methodology. Methods 47 MDS patients were interviewed, US (n = 8, France (n = 9, Germany (n = 9 and the UK (n = 21, to elicit the utility value of TI, RT and TD. Health states were developed based on literature; patient forum discussions; and were validated by a hematologist. Face-to-face interviews used the feeling thermometer Visual Analogue Scale (VAS and the Time Trade-Off (TTO method to value the health states on a 0 (dead to 1 (perfect health scale. Socio-demographic, clinical, and quality-of-life (EQ-5D characteristics were surveyed to describe the patient sample. Results and Discussion The mean age was 67 years (range: 29-83; 45% male, 70% retired; 40% had secondary/high school education, or higher (32%, and 79% lived with family, a partner or spouse, or friends. The mean time from MDS diagnosis was 5 years (range:1-23. Most patients (87% received previous transfusions and 49% had received a transfusion in the last 3 months. Mean EQ-5D index score was 0.78; patients reported at least some problem with mobility (45%, usual activities (40%, pain/discomfort (47%, and anxiety/depression (34%. Few patients had difficulty understanding the VAS (n = 3 and TTO (n = 4 exercises. Utility scores for TI were higher than for RT (0.84 vs. 0.77; p Conclusion Patients value TI, suggesting an important role for new treatments aiming to achieve greater TI in MDS. These results can be used in preference-based health economic evaluation of new MDS treatments, such as in future cost-utility studies.

    To evaluate predictors of allogenic blood transfusion requirements in patients undergoing minimal invasive oesophagectomy at a tertiary high volume centre for oesophago-gastric surgery. Retrospective analysis of all patients undergoing minimal access oesophagectomy in our department between January 2010 and December 2011. Patients were divided into two groups depending on whether they required a blood transfusion at any time during their index admission. Factors that have been shown to influence perioperative blood transfusion requirements in major surgery were included in the analysis. Binary logistic regression analysis was performed to determine the impact of patient and perioperative characteristics on transfusion requirements during the index admission. A total of 80 patients underwent minimal access oesophagectomy, of which 61 patients had a laparoscopic assisted oesophagectomy and 19 patients had a minimal invasive oesophagectomy. Perioperative blood transfusion was required in 28 patients at any time during hospital admission. On binary logistic regression analysis, a lower preoperative haemoglobin concentration (p blood transfusion requirements. It has been reported that requirement for blood transfusion can affect long-term outcomes in oesophageal cancer resection. Two factors which could be addressed preoperatively; haemoglobin concentration and type of oesophageal resection, may be valuable in predicting blood transfusions in patients undergoing minimally invasive oesophagectomy. Our analysis revealed that preoperative haemoglobin concentration, occurrence of significant complications and type of minimal access oesophagectomy predicted blood transfusion requirements in the patient population examined.

    ABSTRACT : INTRODUCTION : The massive-transfusion concept was introduced to recognize the dilutional complications resulting from large volumes of packed red blood cells (PRBCs). Definitions of massive transfusion vary and lack supporting clinical evidence. Damage-control resuscitation regimens...... of modern trauma care are targeted to the early correction of acute traumatic coagulopathy. The aim of this study was to identify a clinically relevant definition of trauma massive transfusion based on clinical outcomes. We also examined whether the concept was useful in that early prediction of massive...... transfusion as a concept in trauma has limited utility, and emphasis should be placed on identifying patients with massive hemorrhage and acute traumatic coagulopathy....

    Organ transplantation recipients present unusual challenges with regard to blood transfusion. Although this patient population requires a larger proportion of blood product resources, liberal transfusion of allogeneic blood products can lead to a plethora of complications. Recent trends suggest that efforts to minimize bleeding, conserve products, and target transfusion to specific deficits and needs are increasingly becoming the standard practice; these must all occur with optimization of graft function and preservation in mind. With newer monitoring modalities and factor concentrates, the approach toward transfusion and bleeding in organ transplantation has rapidly improved in recent years. Copyright © 2017 Elsevier Inc.

    Transfusion services in orthopaedic surgery can lead to unnecessary complications and increased healthcare costs. The objective of this study was to assess treatments and costs associated with blood and blood product transfusions in a historical cohort of 189,457 inpatients in the US and 34,987 inpatients in Belgium undergoing knee or hip surgery. Descriptive analysis, logistic regression and ordinary least squares regression were used to describe the factors associated with the use and cost of allogeneic blood transfusion. Hospitalisation costs for joint replacement surgery totalled $12,718 (SD=6,356) and averaged 4.33 days in the US, while costs in Belgium were $6,526 (SD=3,192) and averaged 17.1 days. The use of low molecular weight heparin and tranexamic acid was much higher in Belgium than the US (36% and 99% compared to 0% and 40%, respectively). Patients in the US spent 12.7 (pcosts per hospitalisation than patients in Belgium. While hospital costs for patients were greater in the US, length of stay was shorter and patients were less likely to have transfusion services than those patients in Belgium. While this study is limited by factors inherent to observational studies, such as omitted variable bias, misclassification, and disease comorbidity, there are substantial differences in the use of blood products between Belgium and the US.

    This study aimed to verify the performance of blood transfusion committees in transfusion services linked to the public blood bank network of the state of Minas Gerais. A cross-sectional observational study was conducted between 2007 and 2008 using questionnaires and proficiency tests to evaluate the reporting and investigation of transfusion reactions comparing transfusion services with and without transfusion committees in the public transfusion services of the state of Minas Gerais. Nineteen of Hemominas own transfusion services and 207 that contracted the services of the foundation located in 178 municipalities were visited between 2007 and 2008. Established transfusion committees were present in 63.4% of the services visited. Transfusion incidents were reported by 53 (36.8%) transfusion services with transfusion committees and by eight (9.6%) without transfusion committees (p < 0.001) with 543 (97.5%) and 14 (2.5%) notifications, respectively. Of the reported transfusion incidents, 40 (75.5%) transfusion services with transfusion committees and only two (25%) of those without transfusion committees investigated the causes. The incidence of notification and investigation of the causes of transfusion reactions was higher in transfusion services where a transfusion committee was present. Despite these results, the performance of these committees was found to be incipient and a better organization and more effective operation are required.

    The administration of blood products is frequently determined by physicians without subspecialty training in transfusion medicine (TM). Education in TM is necessary for appropriate utilization of resources and maintaining patient safety. Our institution developed an efficient simulation-based TM course with the goal of identifying key topics that could be individualized to learners of all levels in various environments while also allowing for practice in an environment where the patient is not placed at risk. A 2.5-hour simulation-based educational activity was designed and taught to undergraduate medical students rotating through anesthesiology and TM elective rotations and to all Clinical Anesthesia Year 1 (CA-1) residents. Content and process evaluation of the activity consisted of multiple-choice tests and course evaluations. Seventy medical students and seven CA-1 residents were enrolled in the course. There was no significant difference on pretest results between medical students and CA-1 residents. The posttest results for both medical students and CA-1 residents were significantly higher than pretest results. The results of the posttest between medical students and CA-1 residents were not significantly different. The TM knowledge gap is not a trivial problem as transfusion of blood products is associated with significant risks. Innovative educational techniques are needed to address the ongoing challenges with knowledge acquisition and retention in already full curricula. Our institution developed a feasible and effective way to integrate TM into the curriculum. Educational activities, such as this, might be a way to improve the safety of transfusions. © 2014 AABB.

  13. Massive transfusion: an overview of the main characteristics and potential risks associated with substances used for correction of a coagulopathy.

    2012-10-01

    Massive transfusion (MT) is an empiric mode of treatment advocated for uncontrolled bleeding and massive haemorrhage, aiming at optimal resuscitation and aggressive correction of coagulopathy. Conventional guidelines recommend early administration of crystalloids and colloids in conjunction with red cells, where the red cell also plays a critical haemostatic function. Plasma and platelets are only used in patients with microvascular bleeding with PT/APTT values >1.5 times the normal values and if PLT counts are below 50×10(9)/L. Massive transfusion carries a significant mortality rate (40%), which increases with the number of volume expanders and blood components transfused. Controversies still exist over the optimal ratio of blood components with respect to overall clinical outcomes and collateral damage. While inadequate transfusion is believed to be associated with poor outcomes but empirical over transfusion results in unnecessary donor exposure with an increased rate of sepsis, transfusion overload and infusion of variable amounts of some biological response modifiers (BRMs), which have the potential to cause additional harm. Alternative strategies, such as early use of tranexamic acid are helpful. However in trauma settings the use of warm fresh whole blood (WFWB) instead of reconstituted components with a different ratio of stored components might be the most cost effective and safer option to improve the patient's survival rate and minimise collateral damage. This manuscript, after a brief summary of standard medical intervention in massive transfusion focuses on the main characteristics of various substances currently available to overcome massive transfusion coagulopathy. The relative levels of some BRMs in fresh and aged blood components of the same origin are highlighted and some myths and unresolved issues related to massive transfusion practice are discussed. In brief, the coagulopathy in MT is a complex phenomenon, often complicated by chronic

    Anaemia is a common feature of lympho-proliferative disorders and is an important cause of poor quality of life in these patients. When indicated, packed red blood cells (PRBC) units are transfused to treat anaemia. Objective of this study was to identify risk factors associated with PRBC transfusions in lymphoma patients. Methods: This was a retrospective study done on Hodgkin lymphoma (HL) and Non-Hodgkin lymphoma (NHL) patients who had PRBC transfusions during chemotherapy. Information regarding gender, type of lymphoma, stage, baseline haemoglobin, marrow involvement and total number of PRBC units transfused was collected. Results: A total of 481 patients with diagnosis of HL and NHL were registered during one year period. Out of these, 108 (22.4%) had PRBC transfusions during treatment. HL and NHL patients were 30 (27.8%) and 78 (72.2%) respectively. NHL patients were older than HL (37 vs. 32 years), (p=0.03). HL patients had lower mean haemoglobin 9. 2.56 g/dl as compared to NHL 11.33 ± 2.42 g/dl, (p<0.05). There was significant difference in number of PRBC units transfused based on lymphoma type (NHL 6.74 ± 5.69 vs. HL 3.97 ± 3.0 units, p<0.05). Bone marrow involvement resulted in increased transfusion requirements (7.84 ± 4.36 vs. 5.26 ± 5.49 units, p<0.05) while stage of disease didn't affected significantly (I/II-4.88 ± 4.85 and III/IV 6.30 ± 5.33 units p=0.2). Conclusion: A significant number of lymphoma patients need PRBC transfusions during chemotherapy. NHL patients and bone marrow involvement makes patients at higher risk for transfusions. In places, where blood bank support is not adequate, patients should be informed right from beginning to arrange donors for possible transfusions during chemotherapy. (author)

    The adequacy and safety of blood transfusion in sub-Saharan Africa is the subject of much concern, yet there have been very few studies of its history. An overview of that record finds that transfusions were first reported in Africa (sub-Saharan and excluding South Africa) in the early 1920s, and organized transfusion practices were established before the Second World War. Blood transfusion grew rapidly after 1945, along with the construction of new hospitals and expanded health services in Africa. Significant differences existed between colonial powers in the organization of transfusion services, but these converged after independence as their use continued to grow and decentralized and hospital-based practices were adopted. It was only after the oil crisis in the mid-1970s that health spending declined and the collection, testing, and transfusion of blood began to level off. Thus, when the AIDS crisis hit transfusion services, they were already struggling to meet the needs of patients. At this time, foreign assistance as well as the World Health Organization and the League of Red Cross Societies helped respond to both the immediate problem of testing blood, and for some countries, support existed for the broader reorganization of transfusion. Overall, the history shows that transfusion was adopted widely and quickly, limited mainly by the availability of knowledgeable doctors and hospital facilities. There was less resistance than expected by Africans to receive transfusions, and the record shows a remarkable flexibility in obtaining blood. The dangers of disease transmission were recognized from an early date but were balanced against the potential lifesaving benefits of transfusion. Copyright © 2013 Elsevier Inc. All rights reserved.

    To test the feasibility of using the penile corpora cavernosa for blood transfusion and resuscitation purposes. Three male donkeys were used for autologous blood transfusion into the corpus cavernosum during three sessions with a 1-week interval between each. Two blood units (450 mL each) were transfused per session to each donkey. Moreover, three dogs were bled up until a state of shock was produced. The mean arterial blood pressure decreased to 60 mm Hg. The withdrawn blood (mean volume 396.3 mL) was transfused back into their corpora cavernosa under 150 mm Hg pressure. Different transfusion parameters were assessed. The Assiut faculty of medicine ethical committee approved the study before its initiation. For the donkey model, the mean time of blood collection was 12 minutes. The mean time needed to establish corporal access was 22 seconds. The mean time of blood transfusion was 14.2 minutes. The mean rate of blood transfusion was 31.7 mL/min. Mild penile elongation with or without mild penile tumescence was observed on four occasions. All penile shafts returned spontaneously to their pretransfusion state at a maximum of 5 minutes after cessation of blood transfusion. No extravasation, hematoma formation, or color changes occurred. Regarding the dog model, the mean rate of transfusion was 35.2 mL/min. All dogs were resuscitated at the end of the transfusion. The corpus cavernosum is a feasible, simple, rapid, and effective alternative route for blood transfusion and venous access. It can be resorted to whenever necessary. It is a reliable means for volume replacement and resuscitation in males.

    Fresh Frozen Plasma (FFP) is a blood component whose clinical use is widespread worldwide. Transfusion safety of this product is ensured by legally obligatory tests. Although these tests are carried out on each plasma donation, safety levels can be further improved by using some technical procedures, such as, among others, methylene blue (MB) and solvent-detergent (SD) viral inactivation methods. The DMTE (Blood Transfusion Unit) in Mantova has used the pharmaceutical-like SD virally inactivated plasma since 2007 (Plasmasafe, Kedrion) as replacement of the PFC by each single donor. Guidelines for the usage of both products are the same. With the main aim of assessing the therapeutic effectiveness and safety of Plasmasafe, we decided to clinically monitor transfusions performed with this product on patients of the Intensive Care Unit at the city hospital in Mantova. In addition, we controlled some coagulation parameters (PT, aPTT, ATIII, Fibrinogen, PC, PS, FV, FVII, FVIII) before and 24 hours after the Plasmasafe infusion. From a clinical point of view, the use of Plasmasafe always led to a significant reduction, or complete stop, of the bleeding. No transfusion-related adverse events were recorded. As regards, the most relevant laboratory results, a marked increase in the above mentioned hemostatic parameters was detected. Furthermore, patients transfused with this product received a mean volume significantly lower than an historical cohort of patients treated with FFP (503 mL with Plasmasafe versus 1549 mL with FFP, Pcost-effective treatment, able to rapidly correct hemostatic abnormalities, for critical patients.

    Obstetrical hemorrhage remains a leading cause of maternal mortality worldwide. New concepts involving the pathophysiology of hemorrhage have been described and include early activation of both the protein C and fibrinolytic pathways. New strategies in hemorrhage treatment include the use of hemostatic resuscitation, although the optimal ratio to administer the various blood products is still unknown. Massive transfusion protocols involve the early utilization of blood products and limit the traditional approach of early massive crystalloid-based resuscitation. The evidence behind hemostatic resuscitation has changed in the last few years, and debate is ongoing regarding optimal transfusion strategies. The use of tranexamic acid, fibrinogen concentrates, and prothrombin complex concentrates has emerged as new potential alternative treatment strategies with improved safety profiles.

    Full Text Available The Transfusion Medicine Service (TMS covers diverse clinical and laboratory-based services that must be delivered with accuracy, efficiency and reliability. TMS oversight is shared by multiple regulatory agencies that cover product manufacturing and validation standards geared toward patient safety. These demands present significant informatics challenges. Over the past few decades, TMS information systems have improved to better handle blood product manufacturing, inventory, delivery, tracking and documentation. Audit trails and access to electronic databases have greatly facilitated product traceability and biovigilance efforts. Modern blood bank computing has enabled novel applications such as the electronic crossmatch, kiosk-based blood product delivery systems, and self-administered computerized blood donor interview and eligibility determination. With increasing use of barcoding technology, there has been a marked improvement in patient and specimen identification. Moreover, the emergence of national and international labeling standards such as ISBT 128 have facilitated the availability, movement and tracking of blood products across national and international boundaries. TMS has only recently begun to leverage the electronic medical record to address quality issues in transfusion practice and promote standardized documentation within institutions. With improved technology, future growth is expected in blood bank automation and product labeling with applications such as radio frequency identification devices. This article reviews several of these key informatics issues relevant to the contemporary practice of TMS.

    Hepatitis E virus (HEV) is a non-enveloped RNA virus transmitted by the fecal-oral route. Autochthonous hepatitis E occurring in developed countries is caused by genotypes 3 and 4 and is a zoonotic infection. Humans are infected mostly after ingestion of undercooked meat from infected animals. Most HEV 3 and 4 infections are clinically inapparent. However, genotype 3 (HEV 3) can lead to chronic hepatitis in immuno-compromised patients such as organ-transplant recipients and patients with haematological malignancies. In Europe, HEV 3 is implicated in transfusion-transmitted HEV infection. In France, as observed in several European countries, prevalence of HEV RNA and specific IgG antibodies are high indicating that viral circulation is important. The systematic HEV NAT screening of blood donations used for preparation of solvent detergent plasma indicate that 1 to 2218 donation is infected by HEV RNA. The need or implementation's impacts of safety measures to prevent HEV transmission by blood transfusion are under reflexion by French's health authorities. The HEV NAT screening is the only available tool of prevention. Alternative strategies are under investigation including individual or mini pool NAT testing all or part of blood donations.

    Full Text Available OBJECTIVE: To determine oxygen derived parameters, hemodynamic and biochemical laboratory data (2,3 Diphosphoglycerate, lactate and blood gases analysis in patients after cardiac surgery who received massive blood replacement. DESIGN: Prospective study. SETTING: Heart Institute (Instituto do Coração, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo, Brazil. PARTICIPANTS: Twelve patients after cardiac surgery who received massive transfusion replacement; six of them evolved to a fatal outcome within the three-day postoperative follow-up. MEASUREMENTS AND MAIN RESULTS: The non-survivors group (n=6 presented high lactate levels and low P50 levels, when compared to the survivors group (p<0.05. Both groups presented an increase in oxygen consumption and O2 extraction, and there were no significant differences between them regarding these parameters. The 2,3 DPG levels were slightly reduced in both groups. CONCLUSIONS: This study shows that patients who are massively transfused following cardiovascular surgery present cell oxygenation disturbances probably as a result of O2 transport inadequacy.

    The Transfusion Medicine Service (TMS) covers diverse clinical and laboratory-based services that must be delivered with accuracy, efficiency and reliability. TMS oversight is shared by multiple regulatory agencies that cover product manufacturing and validation standards geared toward patient safety. These demands present significant informatics challenges. Over the past few decades, TMS information systems have improved to better handle blood product manufacturing, inventory, delivery, tracking and documentation. Audit trails and access to electronic databases have greatly facilitated product traceability and biovigilance efforts. Modern blood bank computing has enabled novel applications such as the electronic crossmatch, kiosk-based blood product delivery systems, and self-administered computerized blood donor interview and eligibility determination. With increasing use of barcoding technology, there has been a marked improvement in patient and specimen identification. Moreover, the emergence of national and international labeling standards such as ISBT 128 have facilitated the availability, movement and tracking of blood products across national and international boundaries. TMS has only recently begun to leverage the electronic medical record to address quality issues in transfusion practice and promote standardized documentation within institutions. With improved technology, future growth is expected in blood bank automation and product labeling with applications such as radio frequency identification devices. This article reviews several of these key informatics issues relevant to the contemporary practice of TMS.

    Massive transfusion is the clinical scenario where the presumed adverse effects of stored blood are expected to be more evident because the whole patient's blood volume is replaced by stored blood. To analyse the association between age of transfused red blood cells (RBC) and survival in massively transfused patients. In this retrospective study, clinical and transfusion data of all consecutive patients massively transfused between 2008 and 2014 in a large, tertiary-care hospital were electronically extracted from the Transfusion Service database and the patients' electronic medical records. Prognostic factors for in-hospital mortality were investigated by multivariate logistic regression. A total of 689 consecutive patients were analysed (median age: 61 years; 65% males) and 272 died in-hospital. Projected mortality at 2, 30, and 90 days was 21%, 35% and 45%, respectively. The odds ratio (OR) for in-hospital mortality among patients who survived after the 2nd day increased with patient age (OR: 1.037, 95% CI: 1.021-1.054; per year Ptransfused in the first 48hours (OR: 1.060; 95% CI: 1.038-1.020 per unit; Ptransfusion was associated with a higher proportion of old RBCs transfused in the first 48hours. Other factors associated with poor prognosis were older patient's age and larger volumes of transfused RBCs. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  9. Advances and controversies in neonatal ICU platelet transfusion practice.

    Science.gov (United States)

    Christensen, Robert D

    2008-01-01

    Some of the platelet transfusions currently given to NICU patients are unnecessary and convey no benefits. Although ordered with good intentions, unnecessary platelet transfusions carry known and unknown risks. Identifying and eliminating any unnecessary platelet transfusions in NICUs would be a step toward better care, lower costs, and more careful preservation of blood component resources. A renewed interest in platelet transfusion studies is needed, if essential data is to be gathered to improve NICU platelet transfusion practice. Retrospective studies can be of value: for instance, seeking associations between bleeding events and platelet counts can suggest the possibility of cause and effect relationships. Such studies might identify approximate platelet count levels that convey high hemorrhagic risk and might help focus future prospective trials. Prospective indirect studies also can be of value, for instance, measuring the template bleeding time and the PFA-100 closure time as a function of platelet count and perhaps as a function of circulating platelet mass, and would provide new information with relevance to platelet transfusion benefits. Such studies might give a better awareness of how low the platelet count can fall before platelet plug formation is impaired. It seems inescapable, however, that new, multicentered, randomized, prospective studies are needed, where NICU patients are assigned different platelet transfusion triggers and then carefully tracked for bleeding events and long-term neurodevelopmental outcomes. Only that type of study is likely to generate the evidence base needed for widespread implementation of improvements in NICU platelet transfusion practice.

    Some carcinogenic viruses are known to be transmissible by blood transfusion. Intensive viral screening of transfused blood now exists in most countries. In the UK, high-sensitivity nucleic acid amplification tests for hepatitis C virus were introduced in 1999 and it was thought that this would reduce, and possibly eliminate, transfusion-related liver cancer. We aimed to investigate cancer risk in recipients of blood transfusion in 2000 or after. A total of 1.3 million UK women recruited in 1998 on average were followed for hospital records of blood transfusion and for cancer registrations. After excluding women with cancer or precancerous conditions before or at the time of transfusion, Cox regression yielded adjusted relative risks of 11 site-specific cancers for women with compared to without prior blood transfusion. During follow up, 11 274 (0.9%) women had a first recorded transfusion in 2000 or after, and 1648 (14.6%) of them were subsequently diagnosed with cancer, a mean 6.8 years after the transfusion. In the first 5 years after transfusion there were significant excesses for most site-specific cancers examined, presumably because some had preclinical cancer. However, 5 or more years (mean 8 years) after blood transfusion, there were significant excess risks only for liver cancer (adjusted relative risk = 2.63, 95%CI 1.45-4.78) and for non-Hodgkin lymphoma (adjusted relative risk = 1.74, 1.21-2.51). When analyses were restricted to those undergoing hip or knee replacement surgery, the commonest procedure associated with transfusion, these relative risks were not materially altered. In a large cohort of UK women, transfusions in the 21st century were associated with long-term increased risks of liver cancer and non-Hodgkin lymphoma. Some of these malignancies may have been caused by carcinogenic agents that are not currently screened for in transfused blood. © The Author 2016.

    The aim was to describe transfusion practice in critically ill patients at an international level and evaluate the effects of red blood cell (RBC) transfusion on outcomes in these patients. This was a pre-planned sub-study of the Intensive Care Over Nations audit, which involved 730 ICUs in 84 countries and included all adult patients admitted between 8 May and 18 May 2012, except admissions for routine postoperative surveillance. ICU and hospital outcomes were recorded. Among the 10,069 patients included in the audit, data related to transfusion had been completed for 9553 (mean age 60 ± 18 years, 60% male); 2511 (26.3%) of these had received a transfusion, with considerable variation among geographic regions. The mean lowest hemoglobin on the day of transfusion was 8.3 ± 1.7 g/dL, but varied from 7.8 ± 1.4 g/dL in the Middle East to 8.9 ± 1.9 g/dL in Eastern Europe. Hospital mortality rates were higher in transfused than in non-transfused patients (30.0% vs. 19.6%, p < 0.001) and increased with increasing numbers of transfused units. In an extended Cox proportional hazard analysis, the relative risk of in-hospital death was slightly lower after transfusion in the whole cohort (hazard ratio 0.98, confidence interval 0.96-1.00, p = 0.048). There was a stepwise decrease in the hazard ratio for mortality after transfusion with increasing admission severity scores. More than one fourth of critically ill patients are transfused during their ICU stay, with considerable variations in transfusion practice among geographic regions. After adjustment for confounders, RBC transfusions were associated with a slightly lower relative risk of in-hospital death, especially in the most severely ill patients, highlighting the importance of taking the severity of illness into account when making transfusion decisions.

    The immunologic risk associated to erythrocyte transfusions is bound to the polymorphism of blood group systems and to the respect of blood transfusion regulations. The results of three studies are presented, which were carried out respectively by the French Society of Blood Transfusion, the National Institute of Blood Transfusion and the National Haemovigilance Network. Two hundred and twenty-seven cases of immunologic accidents are analysed using the Kaplan's interpretation model and the traditional method of process analysis. The results show three critical factors in the occurrence of this type of incident: the relevance of the clinical examinations prescribed, the way in which the biological results are taken into account, and the relationship/exchange of information between private and public hospitals, and blood transfusion centers.

    A two-week, French language, clinical research course in transfusion medicine has recently been created at the Pasteur Institute in Paris under the joint leadership of faculty members from the University of California San Francisco (UCSF), the Blood Systems Research Institute (BSRI) and the National Institute of Transfusion of Paris. The goal is to train transfusion professionals from the developing world to conduct clinical research that will contribute to improving the quality of care and safety in transfusion practices in their respective countries. The course provides training on clinical and epidemiological research methods and their potential applications in transfusion medicine. As part of the course, each student develops a study protocol that can be implemented in his/her blood center of hospital.

  18. Toward a patient-based paradigm for blood transfusion.

    Science.gov (United States)

    Farrugia, Albert; Vamvakas, Eleftherios

    2014-01-01

    The current "manufacturing paradigm" of transfusion practice has detached transfusion from the clinical environment. As an example, fresh whole blood in large-volume hemorrhage may be superior to whole blood reconstituted from multiple components. Multicomponent apheresis can overcome logistical difficulties in matching patient needs with fresh component availability and can deliver the benefits of fresh whole blood. Because of the different transfusion needs of patients in emerging economies and the vulnerability of these blood systems to emerging infections, fresh whole blood and multicomponent apheresis can better meet patient needs when compared with transplants of the "manufacturing paradigm". We propose that patient blood management, along with panels of repeat, paid, accredited apheresis and fresh whole-blood donors can be used in emerging economies to support decentralized blood services. This alternative transfusion-medicine paradigm could eventually also be adopted by established economies to focus transfusion medicine on local patient needs and to alleviate the problem of the aging volunteer donor base.

    2018-03-01

    Autologous blood transfusion is a powerful means of improving performance and remains one of the most challenging methods to detect. Recent investigations have identified 3 candidate reticulocytes genes whose expression was significantly influenced by blood transfusion. Using quantitative reverse transcription polymerase chain reaction as an alternative quantitative method, the present study supports that delta-aminolevulinate synthase 2 (ALAS2), carbonic anhydrase (CA1), and solute carrier family 4 member 1 (SLC4A1) genes are down-regulated post-transfusion. The expression of these genes exhibited stronger correlation with immature reticulocyte fraction than with reticulocytes percentage. Moreover, the repression of reticulocytes' gene expression was more pronounced than the diminution of immature reticulocyte fraction and reticulocyte percentage following blood transfusion. It suggests that the 3 candidate genes are reliable predictors of bone marrow's response to blood transfusion and that they represent potential biomarkers for the detection of this method prohibited in sports.

    2017-03-01

    A decade ago, definitions of "transfusionߚrelated acute lung injury (TRALI)" and "possible TRALI" were standardized for research and clinical diagnosis. Since then, evidence has confirmed that TRALI is often due to transfusion of white blood cell antibodies to at-risk patients, and the term "TRALI, antibody mediated" is appropriate for such cases. Other TRALI cases are non-antibody mediated. Because specific, nonantibody transfusion factors have not yet been confirmed to cause TRALI in humans, the general term "TRALI, non-antibody mediated" is appropriate for such cases. In contrast, evidence is against possible TRALI being due to transfusion with the more likely cause of the acute respiratory distress syndrome (ARDS) being the alternative ARDS risk factor present in these patients. We propose to drop the misleading term "possible TRALI" and to rename this category of cases as "transfused ARDS." These nomenclature updates will more accurately categorize ARDS cases that develop after transfusion. © 2016 AABB.

    The purpose of the present study consists in an updated review concerning the transmission of protozoa and worms by blood transfusion and organ transplantation. Prophylactic regimens and possible modifications will be discussed. The literature devoted to tropical medicine in recent years was screened and a search on Medline was performed. Relevant review articles were selected. Transfusion induced malaria and--especially in Latin America--transfusion associated Chagas' disease are the most important of these diseases. Prophylaxis of transfusion malaria is different in different countries, it is based primarily on donor selection and immunodiagnostic examinations. It is recommended that the German guidelines for prevention of transfusion malaria should be modified and that a donor selection should also take place concerning Chagas' disease.

    Background Acute transfusion reactions are probably common in sub-Saharan Africa, but transfusion reaction surveillance systems have not been widely established. In 2008, the Blood Transfusion Service of Namibia implemented a national acute transfusion reaction surveillance system, but substantial under-reporting was suspected. We estimated the actual prevalence and rate of acute transfusion reactions occurring in Windhoek, Namibia. Methods The percentage of transfusion events resulting in a reported acute transfusion reaction was calculated. Actual percentage and rates of acute transfusion reactions per 1,000 transfused units were estimated by reviewing patients’ records from six hospitals, which transfuse >99% of all blood in Windhoek. Patients’ records for 1,162 transfusion events occurring between 1st January – 31st December 2011 were randomly selected. Clinical and demographic information were abstracted and Centers for Disease Control and Prevention National Healthcare Safety Network criteria were applied to categorize acute transfusion reactions1. Results From January 1 – December 31, 2011, there were 3,697 transfusion events (involving 10,338 blood units) in the selected hospitals. Eight (0.2%) acute transfusion reactions were reported to the surveillance system. Of the 1,162 transfusion events selected, medical records for 785 transfusion events were analysed, and 28 acute transfusion reactions were detected, of which only one had also been reported to the surveillance system. An estimated 3.4% (95% confidence interval [CI]: 2.3–4.4) of transfusion events in Windhoek resulted in an acute transfusion reaction, with an estimated rate of 11.5 (95% CI: 7.6–14.5) acute transfusion reactions per 1,000 transfused units. Conclusion The estimated actual rate of acute transfusion reactions is higher than the rate reported to the national haemovigilance system.

    To study the serum ferritin levels in children with acute leukemia, depending on the number of transfusions of RBC concentrate and period of disease. We studied the red blood count, serum iron and ferritin levels in 54 patients with acute leukemia before chemotherapy, at the time of a standardized treatment protocol, and after transfusions of RBC concentrates. In the debute of acute leukemia just before treatment lauch the serum ferritin in 81.5% of children was 2.3-2.5 higher than normal. The need for transfusion of RBC concentrates was higher under serum ferritin level exceeding 500 ng/mL. The association was established between ferritin content and age of the children, variant of acute leukemia and period of the disease. The level of serum ferritin can be used as a marker of ferrokinetic status for timely diagnosis of iron overload in children with acute leukemias and for application of treatment-and-prophylactic actions.

    Management of anemia in surgical oncology patients remains one of the key quality components in overall care and cost. Continued reports demonstrate the effects of hospital transfusion, which has been demonstrated to lead to a longer length of stay, more complications, and possibly worse overall oncologic outcomes. The hypothesis for this study was that a dedicated restrictive transfusion protocol in patients undergoing hepatectomy would lead to less overall blood transfusion with no increase in overall morbidity. A cohort study was performed using our prospective database from January 2000 to June 2013. September 2011 served as the separation point for the date of operation criteria because this marked the implementation of more restrictive blood transfusion guidelines. A total of 186 patients undergoing liver resection were reviewed. The restrictive blood transfusion guidelines reduced the percentage of patients that received blood from 31.0% before January 9, 2011 to 23.3% after this date (P = .03). The liver procedure that was most consistently associated with higher levels of transfusion was a right lobectomy (16%). Prior surgery and endoscopic stent were the 2 preoperative interventions associated with receiving blood. Patients who received blood before and after the restrictive period had similar predictive factors: major hepatectomies, higher intraoperative blood loss, lower preoperative hemoglobin level, older age, prior systemic chemotherapy, and lower preoperative nutritional parameters (all P blood did not have worse overall progression-free survival or overall survival. A restrictive blood transfusion protocol reduces the incidence of blood transfusions and the number of packed red blood cells transfused. Patients who require blood have similar preoperative and intraoperative factors that cannot be mitigated in oncology patients. Restrictive use of blood transfusions can reduce cost and does adversely affect patients undergoing liver resection

    Warm fresh whole blood has been advocated for critical bleeding in the military setting. This study assessed whether unrefrigerated young whole blood transfusion, from donation to transfusion less than 24 hours, could reduce mortality of patients with critical bleeding in a civilian setting. A linked data cohort study was conducted on a total of 353 consecutive patients requiring massive transfusion, defined as 10 units or more of red blood cells or whole blood transfusion within 24 hours, in a quaternary health care center in Australia. Of the 353 patients with massive blood transfusion in the study, 77 received unrefrigerated young whole blood transfusion (mean, 4.0 units; interquartile range, 2-6). The diagnosis, severity of acute illness, age, sex, and ABO blood group were not significantly different between the patients who received unrefrigerated young whole blood and those who did not. Unrefrigerated young whole blood transfusions were associated with a slightly improved coagulation profile (lowest fibrinogen concentrations 1.7g/L vs. 1.4g/L, p=0.006; worst international normalization ratio, 2.4 vs. 2.8, p=0.05) but did not reduce the total utilization of allogeneic blood products and subsequent use of recombinant Factor VIIa (27% vs. 22%, p=0.358). Thirty-day mortality and 8-year survival after hospital discharge (hazard ratio, 1.05; 95% confidence interval, 0.41-2.65; p=0.93) were also not different after the use of unrefrigerated young whole blood transfusion. Unrefrigerated young whole blood transfusion was not associated with a reduced mortality of patients requiring massive transfusion in a civilian setting when other blood products were readily available. © 2010 American Association of Blood Banks.

    Blood products are used for patient treatment and survival in the cases of major surgery, hematological disorders or cancer therapy. Presently the main blood components are not yet replaceable by artificial products and all activities related to blood transfusion is highly dependent on the healthcare development of each country. The World Health Organization Eastern Mediterranean Region (WHO-EMR) comprises of 21 member states with variable socio-economic status effective on blood transfusion activities. The fundamental motivation behind this research was to accumulate some data of blood practices in this region and to have an appropriate image of the WHO-EMR region. The data were collected through the published papers or data, blood transfusion services websites, and the other health official websites like WHO. Among WHO-EMR countries there are some with a nationally organized blood transfusion establishment such as Egypt, Iran, Iraq, Kuwait, Morocco, Oman, Pakistan, and Syria. In a few, blood transfusion administrations are hospital-based like Saudi Arabia. The others are run by Red Crescent such as Bahrain, Tunisia and UEA or by Red Cross like Lebanon. Only Iran and UAE succeed to have 100% voluntary non-remunerated blood donors; however, most of them are still under the weight of family/replacement blood donation such as Afghanistan, Egypt, Iraq, Lebanon, Morocco, Saudi Arabia and Sudan or even paid donors like Pakistan and Yemen. The haemovigilance and training programs have been implemented in some countries including Bahrain, Iran, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Tunisia and UAE. Unfortunately, there are rare and inaccessible information about some EMR states like Djibouti, Palestine and Somalia so that little data can be independently discovered. In these countries different measures ought to be additionally designated to ensure blood products adequacy and safety such as the development of well-coordinated national blood transfusion centers with

    An automated blood exchange transfusion (BET) with a two-site technique has been devised by Goldmann et al and by us, using an infusion pump. With this method, we successfully performed exchange transfusions 189 times in the past four years on 110 infants with birth weights ranging from 530 g to 4,000 g. The exchange rate by the automated method was compared with the rate by Diamond's method. Serum bilirubin (SB) levels before and after BET and the maximal SB rebound within 24 hours after BET were: 21.6 +/- 2.4, 11.5 +/- 2.2, and 15.0 +/- 1.5 mg/dl in the automated method, and 22.0 +/- 2.9, 11.2 +/- 2.5, and 17.7 +/- 3.2 mg/dl in Diamond's method, respectively. The result showed that the maximal rebound of the SB level within 24 hours after BET was significantly lower in the automated method than in Diamond's method (p less than 0.01), though SB levels before and after BET were not significantly different between the two methods. The exchange rate was also measured by means of staining the fetal red cells (F cells) both in the automated method and in Diamond's method, and comparing them. The exchange rate of F cells in Diamond's method went down along the theoretical exchange curve proposed by Diamond, while the rate in the automated method was significantly better than in Diamond's, especially in the early stage of BET (p less than 0.01). We believe that the use of this automated method may give better results than Diamond's method in the rate of exchange, because this method is performed with a two-site technique using a peripheral artery and vein.

    Failure Mode and Effect Analysis (FMEA) is a method used to assess the risk of failures and harms to patients during the medical process and to identify the associated clinical issues. The aim of this study was to conduct an assessment of blood transfusion process in a teaching general hospital, using FMEA as the method. A structured FMEA was recruited in our study performed in 2014, and corrective actions were implemented and re-evaluated after 6 months. Sixteen 2-h sessions were held to perform FMEA in the blood transfusion process, including five steps: establishing the context, selecting team members, analysis of the processes, hazard analysis, and developing a risk reduction protocol for blood transfusion. Failure modes with the highest risk priority numbers (RPNs) were identified. The overall RPN scores ranged from 5 to 100 among which, four failure modes were associated with RPNs over 75. The data analysis indicated that failures with the highest RPNs were: labelling (RPN: 100), transfusion of blood or the component (RPN: 100), patient identification (RPN: 80) and sampling (RPN: 75). The results demonstrated that mis-transfusion of blood or blood component is the most important error, which can lead to serious morbidity or mortality. Provision of training to the personnel on blood transfusion, knowledge raising on hazards and appropriate preventative measures, as well as developing standard safety guidelines are essential, and must be implemented during all steps of blood and blood component transfusion.

    The transfusion experience for a 1-year period (September 1985 to August 1986) at a tertiary referral obstetric hospital was reviewed retrospectively. During the review period 7731 mothers were delivered and 6003 patients (83%) underwent type-and-screen procedures. A total of 1057 units of red blood cells were crossmatched, and 362 of these 1057 units were transfused to 100 parturient women so that the overall crossmatch/transfusion ratio was 2.9:1. Five percent of transfused patients received 1 unit; 52% of patients received 2 units, 19% received 3 units and 24% received greater than or equal to 4 units of packed red blood cells. Major indications for transfusion were uterine atony, 27%; retained placenta, 17%; trauma, 17%, placenta previa, 7%; and abruptio placentae, 5%. In 12% of patients transfusions were done because of anemia. This study shows the value of audit and confirms that the type-and-screen procedure is an effective way of reducing the crossmatch/transfusion ratio without compromising patient care, even in high-risk patients.

    Full Text Available Introduction: Safest blood a patient can receive is his own. Quest for safe blood transfusion has remained of prime concern. To meet this aspiration, various forms of autologous blood transfusions can be practiced. It is especially suitable for patients with rare blood groups and religious sects such as Jehovah′s witness autologous transfusion is extremely safe. Cross matching is not required; iso-immunization to a foreign body is excluded. Fear of transfusion transmissible disease can be ignored. Therefore, autologous blood transfusion is required to be revisited. Materials and Methods: This is a prospective study carried out at Padmashree Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pune between July 2010 and May 2012. Study comprised of 100 patients divided into two groups, autologous and homologous. Benefits of autologous transfusion were studied. Results: There was no significant change in hematocrit and blood parameters after blood donation. That is mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration (P < 0.001 after blood donation. Only one complication of vasovagal syncope was observed at the time of blood donation. Conclusion: Autologous blood transfusion is safe. Easy alternative to be practiced in elective surgeries, especially in patients with rare blood group or believers of Jehovah′s witness faith. It helps to reduce the shortfall in national blood inventory. Autologous blood donation should be practiced whenever possible.

    The prospect of surgery without blood loss is an emerging reality. Use of a blood conservation strategy is gaining increasing recognition as a sound and practical approach, especially for the majority of large blood loss surgeries. However, critical situations still occur in which transfusions are necessary or unavoidable for the short-term survival of the patient. The decision-making processes for determining when to transfuse, which blood products to give, and how much are presented here with an evaluation of the risks of transfusion and a discussion on blood conservation strategies. Modalities that may be used in such strategies include restricted phlebotomy, the implementation of restrictive transfusion triggers, acute normovolemic hemodilution, intraoperative and postoperative blood salvage, and refined operative techniques to achieve meticulous hemostasis. In addition, the proper use of erythropoiesis-stimulating agents well before surgery can reduce the number of units transfused. The risks and costs of allogeneic blood transfusions underscore the need for and value of blood conservation techniques. Increasingly, hospitals are adopting blood conservation strategies as part of their routine practice. Blood conservation is a rapidly evolving field in which active research is expanding our understanding of the molecular, physiologic, and clinical aspects of hematopoiesis, circulatory response, coagulation enigmas, artificial oxygen carriers, and the impact of anemia on organ function. Ongoing research offers the possibility of replacement or elimination of allogeneic blood transfusions in a variety of clinical settings.

    2008-06-01

    The ability of hemoglobin based oxygen carrier-201 (HBOC-201) to safely reduce and/or eliminate perioperative transfusion was studied in orthopedic surgery patients. A randomized, single-blind, packed red blood cell (PRBC)-controlled, parallel-group multicenter study was conducted. Six hundred eighty-eight patients were randomized to treatment with HBOC-201 (H, n = 350) or PRBC (R, n = 338) at the first transfusion decision. Primary endpoints were transfusion avoidance and blinded assessment [Mann-Whitney estimator (MW)] of safety noninferiority. Groups were compared directly and by paired/matching group analyses predicated on a prospectively defined dichotomy [treatment success (HH) vs. failure (HR)] in the H arm and an equivalently defined dichotomy [3 (R3+) units PRBC] in the R arm, based on need (moderate vs. high) for additional oxygen carrying capacity. A total of 59.4% of patients in the H arm avoided PRBC transfusion. Adverse events (8.47 vs. 5.88), and serious adverse events (SAEs) (0.35 vs. 0.25) per patient were higher in the H versus R arms (p 80 years), volume overload and undertreatment contributed to this imbalance. HBOC-201 eliminated transfusion in the majority of subjects. The between arms (H vs. R) safety analysis was unfavorable and likely related to patient age, volume overload, and undertreatment and was isolated to patients that could not be managed by HBOC-201 alone. However, patients transfusion when treated with up to 10 units of HBOC-201.

    Transfusion-related acute lung injury (TRALI) is one of the leading causes of death associated with transfusion of blood and blood components. The understanding of the etiology and pathophysiology of this syndrome has much improved during the last decades, nevertheless numerous issues are still unresolved and symptomatic treatment remains the cornerstone of medical management. Consequently more attention is directed at primary as well as secondary prevention. The awareness of the problem within the medical society is still unsatisfactory which results in a high number of unrecognized cases or of inaccurate diagnoses one of which is cardiogenic pulmonary edema. The aim of this review is to make the TRALI syndrome more familiar to clinicians and to emphasize how significant proper medical management is both for the patients presenting TRALI symptoms as well as for future recipients of blood components.

    Full Text Available Patients with non-transfusion-dependent thalassemia (NTDT experience many clinical complications despite their independence from frequent transfusions. Morbidities in NTDT stem from the interaction of multiple pathophysiological factors: ineffective erythropoiesis, iron overload (IOL, and hypercoagulability. Ineffective erythropoiesis and hemolysis are associated with chronic hypoxia and a hypercoagulable state. The latter are linked to a high prevalence of thromboembolic and cerebrovascular events, as well as leg ulcers and pulmonary hypertension. IOL in NTDT patients is a cumulative process that can lead to several iron-related morbidities in the liver (liver fibrosis, kidneys, endocrine glands (endocrinopathies, and vascular system (vascular disease. This review sheds light on the pathophysiology underlying morbidities associated with NTDT and summarizes the mainstays of treatment and some of the possible future therapeutic interventions.

    The paper reports results from a research project with the objective of studying patient safety, and relates the finding to safety issues within transfusion medicine. The background is an increased focus on undesired events related to diagnosis, medication, and patient treatment in general in the healthcare sector. The study is designed as a case study within a regional Norwegian hospital conducting specialised health care services. The study includes multiple methods such as interviews, document analysis, analysis of error reports, and a questionnaire survey. Results show that the challenges for improved patient safety, based on employees' perceptions, are hospital management support, reporting of accidents/incidents, and collaboration across hospital units. Several of these generic safety challenges are also found to be of relevance for a hospital's transfusion service. Positive patient safety factors are identified as teamwork within hospital units, a non-punitive response to errors, and unit manager's actions promoting safety.

    Background There are limited published data on the characteristics of blood transfusion recipients in sub-Saharan Africa. This study describes the demographic characteristics of blood transfusion recipients and patterns of blood and blood component use in Zimbabwe. Materials and methods Data on the characteristics of the blood transfusion recipients (age, sex, blood group), blood components received (type, quantity), discharge diagnoses and outcomes following transfusion (discharge status, duration of stay in hospital), were retrospectively collected from four major hospitals for the period from January 1, 2012 to December 31, 2012. Diagnoses were grouped into broad categories according to the disease headings of the International Classification of Diseases (ICD-10). Surgical procedures were grouped into broad categories according to organ system using ICD-9. Results Most of the 1,793 transfusion recipients studied were female (63.2%) and in the reproductive age group, i.e. 15–49 years (65.3%). The median age of the recipients was 33 years (range, 0–93). The majority of these recipients (n=1,642; 91.6%) received a red blood cell transfusion. The majority of the patients were diagnosed with conditions related to pregnancy and childbirth (22.3%), and diseases of blood and blood-forming organs (17.7%). The median time spent in hospital was 8 days (range, 0–214) and in-hospital mortality was 15.4%. Discussion Our sample of blood transfusion recipients were fairly young and most of them received red blood cell transfusions. The majority of patients in the reproductive age group received blood transfusions for pregnancy and childbirth-related diagnoses. PMID:26192782

    Total knee replacement (TKR) surgery is one of the most frequent and the most extensive procedures in orthopedic surgery, accompanied with some serious complications. Perioperative blood loss is one of the most serious losses, so it is vital to recognize and treat such losses properly. Autologous blood transfusion is the only true alternative for the allogeneic blood. The aim of this study was to to examine if autologous blood transfusion reduces usage of allogenic blood in total knee replacement surgery, as well as to examine possible effect of autologous blood transfusion on postoperative complications, recovery and hospital stay of patients after total knee replacement surgery. During the controlled, prospective, randomised study we compared two groups of patients (n = 112) with total prosthesis implanted in their knee. The group I consisted of the patients who received the transfusion of other people's (allogeneic) blood (n = 57) and the group II of the patients whose blood was collected postoperatively and then given them [their own (autologous) blood] (n = 55). The transfusion trigger for both groups was hemoglobin level of 85 g/L. In the group of patients whose blood was collected perioperatively only 9 (0.9%) of the patients received transfusion of allogeneic blood, as opposed to the control group in which 98.24% of the patients received the transfusion of allogeneic blood (p blood was collected stayed in hospital for 6.18 days, while the patients of the control group stayed 7.67 days (p blood transfusion is a very effective method for reducing consumption of allogenic blood and thus, indirectly for reducing all complications related to allogenic blood transfusion. There is also a positive influence on postoperative recovery after total knee replacement surgery due to the reduction of hospital stay, and indirectly on the reduction of hospital costs.

    Red blood cell transfusion was previously the principle therapy for anemia in CKD but became less prevalent after the introduction of erythropoiesis-stimulating agents. This study used adaptive choice-based conjoint analysis to identify preferences and predictors of transfusion decision-making in CKD. A computerized adaptive choice-based conjoint survey was administered between June and August of 2012 to nephrologists, internists, and hospitalists listed in the American Medical Association Masterfile. The survey quantified the relative importance of 10 patient attributes, including hemoglobin levels, age, occult blood in stool, severity of illness, eligibility for transplant, iron indices, erythropoiesis-stimulating agents, cardiovascular disease, and functional status. Triggers of transfusions in common dialysis scenarios were studied, and based on adaptive choice-based conjoint-derived preferences, relative importance by performing multivariable regression to identify predictors of transfusion preferences was assessed. A total of 350 providers completed the survey (n=305 nephrologists; mean age=46 years; 21% women). Of 10 attributes assessed, absolute hemoglobin level was the most important driver of transfusions, accounting for 29% of decision-making, followed by functional status (16%) and cardiovascular comorbidities (12%); 92% of providers transfused when hemoglobin was 7.5 g/dl, independent of other factors. In multivariable regression, Veterans Administration providers were more likely to transfuse at 8.0 g/dl (odds ratio, 5.9; 95% confidence interval, 1.9 to 18.4). Although transplant eligibility explained only 5% of decision-making, nephrologists were five times more likely to value it as important compared with non-nephrologists (odds ratio, 5.2; 95% confidence interval, 2.4 to 11.1). Adaptive choice-based conjoint analysis was useful in predicting influences on transfusion decisions. Hemoglobin level, functional status, and cardiovascular comorbidities

    The clinical pathologic syndrome of graft-versus-host disease (GVHD) is usually a sequela of bone marrow transplantation. This disorder occurs as a result of recognition by engrafted donor-derived lymphocytes of foreign recipient transplantation antigens. GVHD may also result from engraftment of lymphocytes from other sources, including (1) transfusion of lymphocytes containing blood components, (2) transplacental maternal fetal transfusion, and (3) passive transfer of lymphocytes in solid organ transplantation. The recipients are usually severely immunodeficient and thus incapable of rejecting the transfused lymphocytes. This syndrome may, however, also develop in immunologically competent patients receiving blood products from individuals with histocompatibility antigens not recognized as foreign. 58 refs

    Tonsillectomy is the second most common surgery in children with sickle cell disease. These children are at an increased risk of perioperative complications due to vaso-occlusive events. Although controversial, preoperative blood transfusions are sometimes given in an effort to prevent such complications. The purpose of this study is to analyze trends in the use of blood transfusion for management of children with sickle cell disease (SCD) undergoing tonsillectomy in a national database. Patients in the 1997-2012 KID with a primary procedure matching the ICD-9 procedure code for tonsillectomy (28.2-28.3) and diagnosis code for SCD (282.60-282.69) were examined. Patients were split into groups by blood transfusion status and compared across variables including complication rate, length of stay (LOS), and hospital charges. Statistical analysis included chi-square test for trend, Mann-Whitney U test, and independent t-test. 1133 patients with SCD underwent tonsillectomy. There was a strong positive correlation between increasing chronologic year and the proportion of patients receiving blood transfusions, 47 (30.1%) in 1997 to 78 (42.5%) in 2012 (r = 0.94, p = 0.005). During this period, there was no significant change in the rate of complications (r = -0.1, p = 0.87). Overall, patients receiving blood transfusion had a longer mean LOS (3.1 ± 2.4 days vs. 2.5 ± 2.2 days, p blood transfusion. The rate of complications in the transfusion group, 18 of 352(5.1%), was not significantly different (p = 0.48) from the group without transfusion, 40 of 626 (6.4%). From 1997 to 2012, there was a significant increase in the proportion of patients with SCD receiving perioperative blood transfusions for tonsillectomy. While the frequency of transfusion rose, those who received a transfusion had similar complication rates with increased charges and length of hospital stays compared to those who did not receive a transfusion.

    Full Text Available Background: Blood transfusion is common in infants. Due to the weakened immune system of newborns and the risk of blood transfusion complications, it is necessary to pay more attention following or after to blood transfusion. The aim of this study was to evaluate the frequency and risk factors of blood transfusions in hospitalized neonates. Methods: A cross-sectional study was performed on 1106 infants admitted in the neonatal intensive care unit (NICU of Mustafa Khomeini University Hospital, Tehran, Iran, from spring 2009 to 2012. Frequency and the reason for of blood components transfusion including fresh frozen plasma, platelets, whole blood, packed red blood cells, cryoprecipitate and relationship with gestational age, sex, birth weight, Apgar score, duration of hospitalization, use of mechanical ventilation were assessed. Statistical analysis was performed with SPSS statistical software, version 16 (IBM, Armonk, NY, USA and statistical test, chi-square test, independent t-test and analysis of variance (ANOVA. Results: Among 1106 infants admitted to the neonatal intensive care unit, 221 infants (%19.98 received blood products. 82 of all (37% were female and 139 (%63 were female. 113 (51% of neonate were preterm and 108 (48% were term. From 361 times of blood transfusions, 121 infant (54.75% received at least one blood product. The frequency of blood transfusion was between 39 and 1 times, with an average of 3.65 times per infant. Frequency of fresh frozen plasma infusion was 173 (47.9%, packed cell 122 (33%, platelet 32 (8.8%, cryoprecipitate 20 (5.1% and whole blood 3 unit (0.83%.

    Full Text Available Gaetano ChiricoNeonatology and Neonatal Intensive Care Unit, Children Hospital, Spedali Civili, Brescia, ItalyAbstract: Preterm neonates, especially very low birth weight infants, remain a category of patients with high transfusion needs; about 90% of those with <1,000 g birth weight may be transfused several times during their hospital stay. However, neonatal red blood cells (RBC transfusion is not without risks. In addition to well-known adverse events, several severe side effects have been observed unique to preterm infants, such as transfusion-related acute gut injury, intraventricular hemorrhage, and increased mortality risk. It is therefore important to reduce the frequency of RBC transfusion in critically ill neonates, by delayed clamping or milking the umbilical cord, using residual cord blood for initial laboratory investigations, reducing phlebotomy losses, determining transfusion guidelines, and ensuring the most appropriate nutrition, with the optimal supplementation of iron, folic acid, and vitamins. Ideally, RBC transfusion should be tailored to the individual requirements of the single infant. However, many controversies still remain, and the decision on whether to transfuse or not is often made on an empirical basis. Recently, a few clinical trials have been performed with the aim to compare the risk/benefit ratio of restrictive versus liberal transfusion criteria. No significant differences in short-term outcomes were observed, suggesting that the restrictive criteria may reduce the need for transfusion and the related side effects. Neurodevelopmental long-term outcome seemed more favorable in the liberal group at first evaluation, especially for boys, and significantly better in the restrictive group at a later clinical investigation. Magnetic resonance imaging scans, performed at an average age of 12 years, showed that intracranial volume was substantially smaller in the liberal group compared with controls. When sex effects

    Every year, about 210 million women become pregnant. Postpartum hemorrhage (PPH) is one of the major complications of pregnancy, accounting for 14 million cases annually. Of these, it is estimated that around 140,000 women die, resulting in a case fatality rate of 1%. PPH is defined by WHO as a blood loss > or = 500 mls. Most instances of PPH occur suddenly and without warning even in women without any of the known risks for this condition. If women do not receive timely medical treatment, as is often the case in many parts of the world, death can occur within two hours. The chance of receiving a safe blood transfusion as part of the therapy for PPH varies enormously from country to country, depending on whether a safe blood transfusion program has been set up as a part of the national health policy. The increasing realization of the potential deleterious effects of blood transfusion, including exposure to HIV and other viral agents, has changed the practices that were previously acceptable for the transfusion of blood, as has the recent recognition of specific patients who will benefit from a single unit of blood. In countries with limited resources, where a majority of women have anemia at the onset of their pregnancies, the slightest deviation from normality during labor and/or delivery leading to excessive hemorrhage can put a women's life at risk. In these instances, the patient needs urgent resuscitation, stabilization and transfer to a nearby center. Available blood, preferably typed cross matched and screened for infections, should be given until the patient receives specific treatment. This is especially true in bled- out obstetrics patients, where one unit may make the difference between a near death state and the possibility of slow recovery and survival.

    Full Text Available Background: Increased costs and mortality associated with inappropriate blood transfusions have led to investigations about blood request and blood transfusion techniques. We investigated the transfusion status in patients who underwent orthopedic surgery in Poursina Hospital (Rasht, Iran to optimizing blood usage and determine if a scheduled transfusion program for every orthopedic surgery could improve blood transfusion management. Method: In this descriptive-prospective study, all orthopedic surgeries in Poursina Hospital, Rasht, between April to June 2013 were reviewed. All patient information was recorded, including: demographics, type of surgery, hemoglobin level, cross-match test, duration of surgery, and blood loss, and transfusion. Based on the one-way ANOVA and independent samples test analysis, cross-match to transfusion ratio and transfusion possibility, the transfusion index, and maximal surgical blood order schedule were calculated to determine blood transfusion status. Results: Among 872 selected orthopedic surgery candidates, 318 of them were cross-matched and among those, 114 patients received a blood transfusion. In this study, the cross-match to transfusion ratio was 6.4, transfusion possibility 36.47%, transfusion index 0.6, and maximal surgical blood order schedule 0.9. Conclusion: We found that blood ordering was moderately higher than the standard; so it is highly recommended to focus on the knowledge of evidence based on transfusion and standard guidelines for blood transfusion to avoid over-ordering.

    Background Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation. This is an update of a Cochrane Review first published in 2002, and last updated in 2013. Objectives To assess risks and benefits of chronic blood transfusion regimens in people with sickle cell disease for primary and secondary stroke prevention (excluding silent cerebral infarcts). Search methods We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 04 April 2016.

    The aim of this study was to provide an overview of massive transfusion in Chinese hospitals, identify the important indications for massive transfusion and corrective therapies based on clinical evidence and supporting experimental studies, and propose guidelines for the management of massive transfusion. This multiregion, multicenter retrospective study involved a Massive Blood Transfusion Coordination Group composed of 50 clinical experts specializing in blood transfusion, cardiac surgery, anesthesiology, obstetrics, general surgery, and medical statistics from 20 tertiary general hospitals across 5 regions in China. Data were collected for all patients who received ≥10 U red blood cell transfusion within 24 hours in the participating hospitals from January 1 2009 to December 31 2010, including patient demographics, pre-, peri-, and post-operative clinical characteristics, laboratory test results before, during, and after transfusion, and patient mortality at post-transfusion and discharge. We also designed an in vitro hemodilution model to investigate the changes of blood coagulation indices during massive transfusion and the correction of coagulopathy through supplement blood components under different hemodilutions. The experimental data in combination with the clinical evidence were used to determine the optimal proportion and timing for blood component supplementation during massive transfusion. Based on the findings from the present study, together with an extensive review of domestic and international transfusion-related literature and consensus feedback from the 50 experts, we drafted the guidelines on massive blood transfusion that will help Chinese hospitals to develop standardized protocols for massive blood transfusion.

    Reducing perioperative blood loss and transfusion requirements is important in the operative treatment of idiopathic scoliosis. This can be achieved with special frames, cell saver systems, pharmacologic aspects, and other techniques. Recently there has been interest in bipolar sealer devices as an adjunct to traditional monopolar electrocautery. However, there is limited information on this device in pediatric spinal deformity surgery. We reviewed our experience with this device in a setting of a standard institutional operative carepath. Perioperative blood loss and transfusion requirements of 50 consecutive patients with adolescent idiopathic scoliosis undergoing a posterior spinal fusion and segmental spinal instrumentation and who had a bipolar sealer device used during their surgery was compared with a control group of the 50 preceding consecutive patients who did not. Anesthesia, surgical technique, use of intraoperative epsilon aminocaproic acid (Amicar), postoperative protocol, and indications for transfusions (hemoglobin≤7.0 g/dL) were identical in both groups. The preoperative demographics for the patients in both groups were statistically the same. The bipolar sealer group demonstrated a significant reduction in intraoperative estimated blood loss, total perioperative blood loss, volume of blood products transfused, and overall transfusion rate when compared with the control group. When subgroups consisting of only hybrid or all-pedicle screw constructs were considered individually, these findings remained consistent. There were no complications associated with the use of this device. Using the bipolar sealer device is a significant adjunct in decreasing perioperative blood loss and transfusion requirements in patients undergoing surgery for adolescent idiopathic scoliosis. Level III-retrospective comparative study.

    The new French law about clinical laboratory medicine, the requirements of the ISO/CEI 15189 standard, the numerous abilities expected from the medical laboratory technologists and their involvement in blood bank management has led the working group "Recherche et démarche qualité" of the French Society of Blood Transfusion to initiate an inventory of blood transfusion teaching syllabus for medical laboratory technology students and to propose transfusion medicine teaching guidelines. Seven worksheets have been established for that purpose including red blood cell antigen typing and antibody screening, blood sampling in immunohaematology, automation, clinical practices, blood products, blood delivery and haemovigilance. These guidelines aim at contributing to the harmonization of transfusion medicine teaching and at providing objective elements to the medical laboratory managers regarding the practical and theoretical skills of theirs collaborators.

    2010-01-01

    The β-globin gene mutation in sickle cell anemia results in anemia and repeated bouts of vascular occlusion. The cumulative effect of these vasocclusive events is progressive damage to many organs including the kidneys, lungs, and brain. The transfusion of red blood cells (RBC) can ameliorate many of these complications, but can be associated with both acute and chronic complications, including iron overload. The objective of the Best Practices in Transfusion Medicine for Patients with Sickle Cell Disease (SCD) Conference was to review the available published evidence and clinical experience surrounding the use of RBC transfusions for sickle cell disease by a panel of experts. The expert panel developed explicit clinical guidelines for the use of RBC in SCD patients. The panel also made recommendations for further research. A set of guidelines were produced for dissemination to pertinent stakeholders. If implemented, these clinical pathways have the potential to optimize the use of red blood cell transfusions in SCD.

    The aim of this paper is, first, to know the actual situation of the perioperatory red cell transfusion for elective surgery in our hospital. In a second phase and prospectively, we tested guidelines for red cell perioperatory transfusion in order to observe the change of transfusions. Then, we compared the results between the basal and postintervention periods. We performed an aleatory assay with two periods, basal and interventionist. Basal period: 151 patients undergoing elective surgery with perioperatory blood requested and general anesthesia. Intervention period: We applied a transfusion guidelines protocol for perioperatory red cell transfusion from the Hospital's Transfusion Committee, also a questionnaire to evaluate the medical indication; We studied 164 patients with clinical features like the basal period. Study/results variables: preoperative blood request, perioperatively transfusion, number of packed red-cell units transfused, crossmatch--to--transfusion ratio, haemoglobin level pre and posttransfusion. No significant drop of the cross match-transfusion ratio was observed after intervention. There is a slight reduction of the crossmatch--to--transfusion ratio, although these value is high (4.48), due to an increase of the transfusion keeping the percentage of appropriate transfusions. The most frequent reason (53%) of inadequate transfusion is the active bleeding. 1) The transfusional activity of the Marina Alta Hospital supposes approximately 17% of the request and 6% of the global transfusion. 2) The introduction of a protocol of perioperative transfusion instructions suppose a small decrease of the crossmatch--to--transfusion ratio, without statistical significance. This slight reduction is due to an increase of transfusion in the post-intervention period, since in this period there is a group of older age patients and with greater percentage of associated pathology. 3) The rate of appropriate transfusions in both periods is similar. 4) The

Julian Savulescu and Richard W Momeyer argue that informed consent should be based on rational beliefs and that the refusal of blood transfusions by JWs is irrational, but after examining the reasons given by JWs, I challenge the claim that JW beliefs are irrational. I also question whether we should give up the traditional notion of informed consent.

    Managing haemostasis in patients undergoing cardiopulmonary bypass (CPB) surgery remains a challenge. There is no established laboratory test to predict transfusion requirements in cardiac surgery. We investigated whether preoperative Thromboelastography (TEG) with Platelet Mapping Assay (PMA......) or Multiple Electrode Aggrometry (MEA) could predict transfusion requirements in patients undergoing elective coronary artery bypass grafting (CABG) or combined CABG with aortic or mitral valve replacement. We prospectively investigated 199 patients undergoing elective CABG or combined procedures. PMA and MEA...

    Abstract Based on the mechanism of pathophysiology, thalassemia major or transfusion-dependent thalassemia patients may have an increased risk of developing organic erectile dysfunction resulting from hypogonadism. However, there have been few studies investigating the association between erectile dysfunction and transfusion-naive thalassemia populations. We constructed a population-based cohort study to elucidate the association between transfusion-naive thalassemia populations and organic erectile dysfunction This nationwide population-based cohort study involved analyzing data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending to the end of 2011. We identified men with transfusion-naive thalassemia and selected a comparison cohort that was frequency-matched with these according to age, and year of diagnosis thalassemia at a ratio of 1 thalassemia man to 4 control men. We analyzed the risks for transfusion-naive thalassemia men and organic erectile dysfunction by using Cox proportional hazards regression models. In this study, 588 transfusion-naive thalassemia men and 2337 controls were included. Total 12 patients were identified within the thalassaemia group and 10 within the control group. The overall risks for developing organic erectile dysfunction were 4.56-fold in patients with transfusion-naive thalassemia men compared with the comparison cohort after we adjusted for age and comorbidities. Our long-term cohort study results showed that in transfusion-naive thalassemia men, there was a higher risk for the development of organic erectile dysfunction, particularly in those patients with comorbidities.

    Objective To analyze the characteristics of patients who needed a blood transfusion due to epistaxis-caused anemia and to define potential risk factors. Design Retrospective cohort study. Setting A total cohort of 591 epistaxis patients, prospectively included between March 2007 and April 2008 at the ENT department of the University Hospital of Zurich, was evaluated concerning the need for blood transfusions. Methods The clinical charts and medical histories of these patients were evaluated. Main outcome measures Common parameters that increase the risk for severe anemia due to epistaxis. Results Twenty-two patients required blood transfusions due to their medical condition. 22.7% suffered from traumatic nosebleeds. Another 27.3% had a known medical condition with an increased bleeding tendency. These proportions were significantly higher than in the group of patients without need of blood transfusion. The odds ratio for receiving a blood transfusion was 14.0 in patients with hematologic disorders, 4.3 in traumatic epistaxis and 7.7 in posterior bleeders. The transfusion-dependent epistaxis patients suffered significantly more often from severe posterior nosebleeds with the need for a surgical therapeutic approach. Conclusions Patients with severe nosebleeds either from the posterior part of the nose or with known hematologic disorders or traumatic epistaxis should be closely monitored by blood parameter analyses to evaluate the indication for hemotransfusion. The acronym THREAT (Trauma, Hematologic disorder, and REAr origin of bleeding → Transfusion) helps to remember and identify the factors associated with an increased risk of receiving blood transfusion.

    To investigate the impacts of perioperative blood transfusion on the immune function and prognosis in colorectal cancer (CC) patients. A retrospective analysis was conducted in 1404 CC patients, including 1223 sporadic colorectal cancer (SCC) patients and 181 hereditary colorectal cancer (HCC) patients. Among them, 701 SCC and 102 HCC patients received perioperative blood transfusion. The amount of T lymphocyte subsets and natural killer (NK) cells was measured. All patients received a 10-year follow-up and relapse, metastasis and curative conditions were recorded. In SCC group, mortality, local recurrence and distant metastasis rate of transfused patients were significantly higher than non-transfused patients (all P transfused patients than non-transfused patients (P = 0.002). SCC patients transfused with ≥3 U of blood had significantly higher mortality than patients transfused with blood transfusion in SCC and HCC patients (all P blood transfusion (P blood transfusion had markedly lower 10-year survival rates as compared with those who did not receive (both P transfused with ≥3 U of blood had remarkably lower survival rates compared with SCC patients transfused with blood transfusion could impact immune function, increased postoperative mortality, local recurrence rate and distant metastasis rate in CC patients; and survival rate of CC patients is negatively related to blood transfusion volume.

    If a patient suffers any damage from treatment, the persons involved in transfusion medicine might be made liable according to civil and penal law for violations against the standards prescribed by the codes of performance and ethics of the individual professions. In order to avoid organisational liability, criteria for adequate patient care must be created which regulate facilities and equipment as well as staff. The typical hazards encountered in interdisciplinary cooperation between specialists of various branches of medicine must be counteracted by a constructive division of tasks and responsibilities. The participating physicians are moreover liable within the scope of the German law forbidding so-called 'unlawful interference with the possession of another' in the case of failure to obtain legally binding consent--usually resulting from inadequacies in informing the patient. The landmark decision by the German Federal Court of Justice on instructing patients about the risks of and alternatives to blood transfusions forces all those involved to take the consequences with regard to instructing patients about the risk of transfusions and concerning the implementation of techniques for sparing and replacing allogenic blood.

    Blood transfusion is an important transmission route of Trypanosoma cruzi (T cruzi), a major parasitic infection in Central and South America. The limited treatment options are most effective in acute Chagas' infection. At present, there is no current data on the prevalence of T cruzi in the blood donor population of Guyana. This information is necessary to protect the supply of the blood donation programme. This study sought to determine the prevalence of T cruzi in the blood supply at the National Blood Transfusion Services of Guyana with the hope of providing knowledge to the on-going surveillance for Chagas' disease worldwide and therefore address the risk of its spread by blood transfusion. Two commercialized ELISAs utilizing crude or recombinant T cruzi antigens were used to study 2000 blood samples voluntarily donated for the purpose of altruistic or family replacement donation retrospectively. The results showed that approximately 1 in 286 donations tested positive for antibodies to T cruzi. These results indicate that T cruzi continues to be a risk in Guyana and there is a need to continue screening donated blood. Trypanosoma cruzi is a life-long infection and infected persons may be asymptomatic chronic carriers of the disease. Education, housing improvement, and controlled use of insecticides should be introduced to contain Chagas' disease.

    Multiple factors exist that contribute to anemia in dogs and cats receiving hemodialysis, can necessitate transfusion. To describe blood product usage in dogs and cats with acute and chronic kidney disease that were treated with intermittent hemodialysis to determine risk factors associated with the requirement for blood product transfusion. 83 cats and 147 dogs undergoing renal replacement therapy at the Animal Medical Center for acute or chronic kidney disease. Retrospective medical record review of all dogs and cats receiving renal replacement therapy for kidney disease, from June 1997 through September 2012. Blood products (whole blood, packed RBCs, or stromal-free hemoglobin) were administered to 87% of cats and 32% of dogs. The number of dialysis treatments was associated with the requirement for transfusion in cats (adjusted OR 2.21, 95% CI 1.13, 4.32), but not in dogs (adjusted OR 0.98, 95% CI 0.95, 1.03). Administration of a blood product was associated with a higher likelihood of death in dogs (OR 3.198, 95% CI 1.352, 7.565; P = .0098), but not in cats (OR 1.527, 95% CI 0.5404, 4.317, P = .2). Veterinary hospitals with a hemodialysis unit should have reliable and rapid access to safe blood products in order to meet the needs of dogs and cats receiving dialysis.

    2004-01-01

    Prior to 1900, blood transfusions were fraught with danger and often caused more complications than the underlying disease. Discovery of the ABO compatibility system in the early twentieth century opened the modern era of blood transfusion, yet ABO incompatibility-as a result of clerical error-remains a significant threat to the recipient today. The risk of disease transmission now includes new and emerging agents, such as Trepanosoma cruzii and West Nile Virus (WNV), as well as other existing pathogens. Transfusion-related immunomodulation (TRIM) presents a further risk to recipient patients. Confounding these problems are shortages of safe blood and the accelerated rise in the cost of blood due to increased testing. Outcome data on transfusion therapy have not always been favorable, particularly in the areas of postoperative infection, systemic inflammatory response syndrome (SIRS), multiple organ failure (MOF), and mortality. Such data have generated extensive efforts to determine association versus underlying cause of post-transfusion complications. In addition, unprecedented global initiatives to minimize the use of allogeneic blood are on the way. Options may include, but are not limited to, the use of "blood substitutes," although validation of such products is still required. In the meantime, blood product conservation techniques should become part of routine transfusion medicine.

    Viral safety remains a major concern in transfusion of blood products. Over years, the control measures applied to blood products were made more and more sophisticated; however, the number of infectious agents, and notably of viruses, that can be transmitted by transfusion is increasing continuously. The aim of this review paper is to actualize that published in the same journal by the same authors in 2011 with more details on some of actual vs virtual viral threats that were identified recently in the field of blood transfusion. The main subjects that are covered successively concern the transmission via transfusion of hepatitis E virus, the frequency of transfusion transmitted arboviruses, transfusion at the time of the Ebola epidemics in West Africa, the debated role of Marseillevirus (giant viruses infecting amoebae and suspected to infect human blood latently), and, finally, the recent report of the identification in blood donors of a new member of the Flaviviridae family. The addition of these new viral risks to those already identified-partially controlled or not-pleads for the urgent need to move forward to considering inactivation of infectious agents in blood products.

    Tranexamic acid (TXA) reduces intraoperative blood loss and transfusions in patients undergoing total knee arthroplasty. Although numerous studies demonstrate the efficacy of intravenous and topical TXA in these patients, few demonstrate the effectiveness and appropriate dosing recommendations of oral formulations. A retrospective cohort study was performed to evaluate differences in transfusion requirements in patients undergoing primary unilateral total knee arthroplasty with either no TXA (n = 866), a single-dose of oral TXA (n = 157), or both preoperative and postoperative oral TXA (n = 1049). Secondary outcomes included postoperative hemoglobin drop, total units transfused, length of stay, drain output, and cell salvage volume. Transfusion rates decreased from 15.4% in the no-oral tranexamic acid (OTA) group to 9.6% in the single-dose OTA group (P < .001) and 7% in the 2-dose group (P < .001), with no difference in transfusion rates between the single- and 2-dose groups (P = .390). In addition, postoperative hemoglobin drop was reduced from 4.2 g/dL in the no-OTA group to 3.5 g/dL in the single-dose group (P < .01) and to 3.4 g/dL in the 2-dose group (P < .01), without a difference between the single- and 2-dose groups (P = .233). OTA reduces transfusions, with greater ease of administration and improved cost-effectiveness relative to other forms of delivery. Copyright © 2017 Elsevier Inc. All rights reserved.

    Between October 2013 and March 2014, French Polynesia experienced the largest Zika virus (ZIKV) outbreak ever described before the emergence of ZIKV in the Americas in 2015. As arbovirus transfusion-transmitted (TT) infections have been previously reported, we hypothesized that transfusion of blood products could also transmit ZIKV. Mitigation strategies to prevent ZIKV-TT infections included nonspecific measures and the implementation of a laboratory developed ZIKV-specific nucleic acid testing (NAT) assay. Donor sera were tested in pools of 3 and constitutive sera of ZIKV-reactive pools were tested individually. Donor sera were tested prospectively and retrospectively. A posttransfusion follow-up of a patient transfused with ZIKV RNA-reactive blood products was implemented. NAT detected 42 blood donor sera as ZIKV RNA reactive of 1505 tested (2.8%). Thirty ZIKV RNA-reactive blood products collected before the implementation of NAT were transfused to 26 recipients. Posttransfusion investigations were conducted by the hemovigilance unit and data were available for 12 recipients. Symptomatic ZIKV-TT infections were not reported. Predonation screening of blood donors, postdonation information, products discard, and quarantine of blood products were not effective enough to prevent transfusion of ZIKV RNA-reactive blood products. ZIKV NAT was an effective measure once implemented to prevent transfusion of ZIKV RNA-reactive blood products but it is difficult to evaluate the effectiveness of this measure to prevent ZIKV-TT infection, which is a rare event. © 2017 AABB.

    Although the safety of the blood supply has been greatly improved, there still remain both infectious and noninfectious risks to the patient. The incidence of noninfectious transfusion reactions is greater than that of infectious complications. Furthermore, the mortality associated with noninfectious risks is significantly higher. In fact, noninfectious risks account for 87-100% of fatal complications of transfusions. It is concerning to note that the majority of pediatric reports relate to human error such as overtransfusion and lack of knowledge of special requirements in the neonatal age group. The second most frequent category is acute transfusion reactions, majority of which are allergic in nature. It is estimated that the incidence of adverse outcome is 18:100,000 red blood cells issued for children aged less than 18 years and 37:100,000 for infants. The comparable adult incidence is 13:100,000. In order to decrease the risks associated with transfusion of blood products, various blood-conservation strategies can be utilized. Modalities such as acute normovolemic hemodilution, hypervolemic hemodilution, deliberate hypotension, antifibrinolytics, intraoperative blood salvage, and autologous blood donation are discussed and the pediatric literature is reviewed. A discussion of transfusion triggers, and algorithms as well as current research into alternatives to blood transfusions concludes this review. © 2010 Blackwell Publishing Ltd.

    Full Text Available The attainment of blood transfusion safety in Nigeria (and probably the rest of Sub-Saharan Africa remains an uphill task due to a number of factors, ranging from shortage of blood, poor implementation of blood transfusion guidelines, infrastructural deficits to high prevalence of transfusion-transmissible infections (TTIs, particularly hepatitis and human immune deficiency viruses. We reviewed available data on blood transfusion practices and safety in Nigeria using the PubMed, PubMed Central, Google Scholar, and African Index Medicus search engines, through a combination of word and phrases relevant to the subject. The World Health Organization has been in the forefront of efforts to establish safe, available, and affordable blood transfusion services in most parts of Africa through encouraging adequate blood donor recruitment, donor blood testing, and collection as well developing strategies for the rational use of blood. Even though modest improvement has been recorded, particularly with regards to donor blood screening for common TTIs, considerable efforts are needed in the form of robust public enlightenment campaigns (on blood donation and continuous system improvement to drive the current transfusion practices in the country toward safety and self-sustenance.

    A 13-year-old girl with an osteosarcoma was treated by surgery and chemotherapy. During three transfusions of apheresis platelet concentrates allergic reactions occurred, partly in spite of premedication with an antihistamine and a corticoid. As the patient declared to be allergic to some foods, in-vitro tests for allergen-specific IgE antibodies were performed and showed markedly positive results for specific IgE to carrot and celery, less so to hazelnut, peanut and a lot of other food antigens. The donor of one of the unsuitable platelet concentrates remembered when questioned, that he had eaten carrots and chocolate with hazelnuts during the evening before platelet donation. Two washed platelet concentrates were transfused without any problem. Furthermore, transfusions of nine red blood cell concentrates and one unit of virus-inactivated frozen pooled plasma were well tolerated. Patients should be asked for allergies previous to transfusions to be alert to allergic reactions in patients with a positive history of food or drug allergies. If premedication with antihistamines does not prevent severe allergic transfusion reactions, transfusion of washed platelet concentrates and of virus-inactivated frozen pooled plasma can be considered. © Georg Thieme Verlag KG Stuttgart · New York.

    Almost 95% of the platelet transfusions (PTs) conducted in the neonatal intensive care unit (NICU) are prophylactic transfusions. Guidelines for prophylactic PTs are based on platelet counts, but not on platelet functions. Nowadays, in order to reduce unnecessary transfusions, utilizing platelet mass index (PMI) was investigated. The aim of study is to find out whether PTs performed in our NICU during last 2 years were in accordance with the current guideline and to evaluate whether the frequency of PTs should be reduced if PMI was considered. Forty-three infants who received 96 prophylactic PTs were enrolled in the study. The guideline utilized in our NICU advocate keeping the platelet count: (a) >100 000 in pre/post-operative, (b) >50 000 in unstable and (c) >20 000 in stable patients. According to PMI criteria, PT should be performed if PMI: (a) platelet functions into account may yield lower transfusion rate, lower costs and better conservation of blood bank resources.

    Full Text Available Abstract Background To report a case of disseminated fusariosis with endogenous endophthalmitis in a patient with acute lymphoblastic leukemia. Transfusion-associated immune modulation secondary to platelet transfusion could play an important role in the pathophysiology of this case. Case Presentation A 9 year-old male with acute lymphoblastic leukemia complicated by pancytopenia and disseminated Intravascular coagulation was given platelet transfusion. He developed disseminated fusariosis and was referred to the ophthalmology team for right endogenous endophthalmitis. The infection was controlled with aggressive systemic and intravitreal antifungals. Conclusion Patients with acute lymphoblastic leukemia are predisposed to endogenous fungal endophthalmitis. Transfusion-associated immune modulation may further increase host susceptibility to such opportunistic infections.

    Recently it was shown that the induction of antibodies against the H-2 antigens after multiple platelet transfusions is due to leukocyte contamination of the platelet suspensions. Pure platelets are not able to induce a primary antibody response. The present study shows that the platelets, however, can be recognized by the immune system but they induce a suppression of the response. Mice pretreated with donor platelets will not give a primary antibody response upon a subsequent injection of donor leukocytes and the survival of donor skin grafts will be prolonged. Similar results were obtained by pretreatment of the responder mice with heat-treated donor leukocytes. Furthermore, repeated injections of heat-treated leukocytes of the recipient strain to the donor before bone marrow grafting, will graft-versus-host mortality. The recipient mice were irradiated and received spleen cell injections. These data show that cells which have only class I antigens on their surface and no activating class II antigens, induce a suppression of the response against class I antigens. (Auth.)

    For over 50 years patients with liver cirrhosis were considered to be at markedly increased risk of bleeding. This dogma was seemingly supported by abnormalities in standard laboratory tests (SLTs), such as the prothrombin time, that were interpreted as indicating a bleeding diathesis. However, publications from the last decade have revealed SLTs to be poor predictors of bleeding and it is now understood that stable patients with cirrhosis have a rebalanced haemostatic system and preserved thrombin generation. Viscoelastic tests (VETs), such as ROTEM® or TEG™ allow dynamic assessment of the entire coagulation process and provide a better illustration of the interactions between pro- and anticoagulants as well as platelets. Despite their documented success in reducing transfusion rates in liver transplantation more than 30 years ago, the adoption of VETs has been met with some resistance and has only recently gained significant momentum. Bleeding risk should be assessed in every patient undergoing invasive intervention and must consider markers of disease severity, underlying coagulation incompetence, anaemia and surgical factors. The recognition that bleeding in this patient cohort is predominantly linked to mechanistic factors such as portal hypertension, rather than primary coagulopathy, has led to a paradigm shift in their perioperative management. Cognizant of their detrimental effect, the use of large volumes of fresh frozen plasma to correct derangements in SLTs has given way to more refined haemostatic management with specific factor concentrates guided by VETs, coupled with measures to minimize portal venous pressure and meticulous surgical hemostasis.

    Red cell alloimmunization is an acknowledged complication of blood transfusion. Current transfusion practices for thalassemia do not cater to this risk. Serological phenotyping is usually not reliable in these cases unless performed before the first transfusion. Under such circumstances, molecular blood grouping is an effective alternative. To perform molecular blood group genotyping in chronically transfused thalassemia patients and assess the risk of antigenic exposure and incidence of alloimmunization with current transfusion protocols. Molecular blood group genotyping was performed for 47 chronically transfused thalassemia patients. Their 1-year transfusion records were retrieved to assess the antigenic exposure and the frequency thereof. Of 47 patients, 6 were already alloimmunized (3 with anti-E and 3 with anti-K) and were receiving the corresponding antigen negative units. We observed that random selection of ABO and Rh D matched units resulted in 57.7% ±8.26% chance of Rh and Kell phenotype matching also. Forty-four patients had received one or more antigenic exposures at least once. The 6 already alloimmunized patients were further exposed to antigens other than the ones they were immunized to. During the study period, only one patient developed an alloantibody, anti-E with exposure to antigens C (92%) and/or E (32%) at each transfusion. Several factors apart from mere antigen exposure may influence the development of alloimmunization as most of our patients received antigenic exposures but not alloimmunized. Our data provide an impetus for future large-scale studies to understand the development of alloimmunization in such patients.

    Full Text Available Background : Children suffering from beta-thalassemia major require repeated blood transfusions which may be associated with dangers like iron overload and contraction of infections such as HIV, HCV, and HBsAg which ultimately curtail their life span. On the other hand, inadequate transfusions lead to severe anemia and general fatigue and debility. Materials and Methods: Data were obtained from 142 beta-thalassemia major patients aged 3 years or more receiving regular blood transfusions at a transfusion centre in Western India from 1 April 2009 to 30 June 2009. The clinical data and laboratory results were subsequently analyzed. Results: Of the 142 patients, 76 (53.5% were undertransfused (mean Hb <10 gm%. 96 (67% of the patients were taking some form of chelation therapy but out of them only 2 (2% were adequately chelated (S. ferritin <1000 ng/ml. 5 (3.5% of the patients were known diabetics on insulin therapy. 103 (72% of the patients were retarded in terms of growth. The prevalence of transfusion-transmitted infections (TTIs such as HCV, HIV, and HBsAg was respectively 45%, 2%, and 2%, with the prevalence of HCV being significantly more than the general population. The HCV prevalence showed positive correlation with the age of the patients and with the total no of blood transfusions received. As many as 15% (6 out of 40 children who were born on or after 2002 were HCV positive despite the blood they received being subjected to screening for HCV. Conclusions: The study suggests the need to step up the transfusions to achieve hemoglobin goal of 10 gm% (as per the moderate transfusion regimen and also to institute urgent and effective chelation measures with the aim of keeping serum ferritin levels below 1000 ng/ml to avoid the systemic effects of iron overload. In addition, strict monitoring of the children for endocrinopathy and other systemic effects of iron overload should be done. Rigid implementation of quality control measures for the

    Background The practice of transfusing red blood cells is still liberal in some centres suggesting a lack of compliance with guidelines recommending transfusion of red blood cells at haemoglobin levels of 6–8 g/dL in the non-bleeding patient. Few databases provide ongoing feedback of data on pre-transfusion haemoglobin levels at the departmental level. In a tertiary care hospital, no such data were produced before this study. Our aim was to establish a Patient Blood Management database based on electronic data capture in order to monitor compliance with transfusion guidelines at departmental and hospital levels. Materials and methods Hospital data on admissions, diagnoses and surgical procedures were used to define the populations of patients. Data on haemoglobin measurements and red blood cell transfusions were used to calculate pre-transfusion haemoglobin, percentage of transfused patients and transfusion volumes. Results The model dataset include 33,587 admissions, of which 10% had received at least one unit of red blood cells. Haemoglobin measurements preceded 96.7% of the units transfused. The median pre-transfusion haemoglobin was 8.9 g/dL (interquartile range 8.2–9.7) at the hospital level. In only 6.5% of the cases, transfusion was initiated at 7.3 g/dL or lower as recommended by the Danish national transfusion guideline. In 27% of the cases, transfusion was initiated when the haemoglobin level was 9.3 g/dL or higher, which is not recommended. A median of two units was transfused per transfusion episode and per hospital admission. Transfusion practice was more liberal in surgical and intensive care units than in medical departments. Discussion We described pre-transfusion haemoglobin levels, transfusion rates and volumes at hospital and departmental levels, and in surgical subpopulations. Initial data revealed an extensive liberal practice and low compliance with national transfusion guidelines, and identified wards in need of intervention. PMID

    The incidence of hip fracture is increasing and it is more common with increasing age. Surgery is used for almost all hip fractures. Blood loss occurs as a consequence of both the fracture and the surgery and thus red blood cell transfusion is frequently used. However, red blood cell transfusion is not without risks. Therefore, it is important to identify the evidence for the effective and safe use of red blood cell transfusion in people with hip fracture. To assess the effects (benefits and harms) of red blood cell transfusion in people undergoing surgery for hip fracture. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (31 October 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library, 2014, Issue 10), MEDLINE (January 1946 to 20 November 2014), EMBASE (January 1974 to 20 November 2014), CINAHL (January 1982 to 20 November 2014), British Nursing Index Database (January 1992 to 20 November 2014), the Systematic Review Initiative's Transfusion Evidence Library, PubMed for e-publications, various other databases and ongoing trial registers. Randomised controlled trials comparing red blood cell transfusion versus no transfusion or an alternative to transfusion, different transfusion protocols or different transfusion thresholds in people undergoing surgery for hip fracture. Three review authors independently assessed each study's risk of bias and extracted data using a study-specific form. We pooled data where there was homogeneity in the trial comparisons and the timing of outcome measurement. We used GRADE criteria to assess the quality (low, moderate or high) of the evidence for each outcome. We included six trials (2722 participants): all compared two thresholds for red blood cell transfusion: a 'liberal' strategy to maintain a haemoglobin concentration of usually 10 g/dL versus a more 'restrictive' strategy based on symptoms of anaemia or a lower haemoglobin concentration, usually 8 g/dL.

    Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in people who are thrombocytopenic due to bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004, and updated in 2012 that addressed four separate questions: prophylactic versus therapeutic-only platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. This review has now been split into four smaller reviews; this review compares different platelet transfusion doses. Objectives To determine whether different doses of prophylactic platelet transfusions (platelet transfusions given to prevent bleeding) affect their efficacy and safety in preventing bleeding in people with haematological disorders undergoing myelosuppressive chemotherapy with or without haematopoietic stem cell transplantation (HSCT). Search methods We searched for randomised controlled trials in the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2015, Issue 6), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950), and ongoing trial databases to 23 July 2015. Selection criteria Randomised controlled trials involving transfusions of platelet concentrates, prepared either from individual units of whole blood or by apheresis, and given to prevent bleeding in people with malignant haematological disorders or undergoing HSCT that compared different platelet component doses (low dose 1.1 × 1011/m2 ± 25%, standard dose 2.2 × 1011/m2 ± 25%, high dose 4.4 × 1011/m2 ± 25%).

    OBJECTIVE To determine the incidence of blood transfusion, mortality rate, and factors associated with transfusion in dogs and cats undergoing liver lobectomy. DESIGN Retrospective case series. ANIMALS 63 client-owned dogs and 9-client owned cats that underwent liver lobectomy at a specialty veterinary practice from August 2007 through June 2015. PROCEDURES Medical records were reviewed and data extracted regarding dog and cat signalment, hematologic test results before and after surgery, surgical method, number and identity of lobes removed, concurrent surgical procedures, hemoabdomen detected during surgery, incidence of blood transfusion, and survival to hospital discharge (for calculation of mortality rate). Variables were compared between patients that did and did not require transfusion. RESULTS 11 of 63 (17%) dogs and 4 of 9 cats required a blood transfusion. Mortality rate was 8% for dogs and 22% for cats. Pre- and postoperative PCV and plasma total solids concentration were significantly lower and mortality rate significantly higher in dogs requiring transfusion than in dogs not requiring transfusion. Postoperative PCV was significantly lower in cats requiring transfusion than in cats not requiring transfusion. No significant differences in any other variable were identified between dogs and cats requiring versus not requiring transfusion. CONCLUSIONS AND CLINICAL RELEVANCE Dogs and cats undergoing liver lobectomy had a high requirement for blood transfusion, and a higher requirement for transfusion should be anticipated in dogs with perioperative anemia and cats with postoperative anemia. Veterinarians performing liver lobectomies in dogs and cats should have blood products readily available.

    The centenary of the start of the First World War has stirred considerable interest in the political, social, military and human factors of the time and how they interacted to produce and sustain the material and human destruction in the 4 years of the war and beyond. Medical practice may appear distant and static and perhaps seems to have been somewhat ineffectual in the face of so much trauma and in the light of the enormous advances in medicine and surgery over the last century. However, this is an illusion of time and of course medical, surgical and psychiatric knowledge and procedures were developing rapidly at the time and the war years accelerated implementation of many important advances. Transfusion practice lay at the heart of resuscitation, and although direct transfusion from donor to recipient was still used, Geoffrey Keynes from Britain, Oswald Robertson from America and his namesake Lawrence Bruce Robertson from Canada, developed methods for indirect transfusion from donor to recipient by storing blood in bottles and also blood-banking that laid the foundation of modern transfusion medicine. This review explores the historical setting behind the development of blood transfusion up to the start of the First World War and on how they progressed during the war and afterwards. A fresh look may renew interest in how a novel medical speciality responded to the needs of war and of post-war society. © 2015 British Blood Transfusion Society.

    BACKGROUND: Allogeneic red blood cell transfusion is frequently used in total hip replacement surgery (THR). However, data on the prognosis of transfused patients are sparse. In this study we compared the risk of complications following THR in transfused and non-transfused patients. METHODS......: A population-based follow-up study was performed using data from medical databases in Denmark. We identified 28,087 primary THR procedures performed from 1999 to 2007, from which we computed a propensity score for red blood cell transfusion based on detailed data on patient-, procedure-, and hospital......-related characteristics. We were able to match 2,254 transfused with 2,254 non-transfused THR patients using the propensity score. RESULTS: Of the 28,087 THR patients, 9,063 (32.3%) received at least one red blood cell transfusion within 8 days of surgery. Transfused patients had higher 90-day mortality compared...

    Full Text Available The currently available data suggest that efforts towards improving the quality of red blood cell (RBC blood bank products should concentrate on: (1 preventing the removal of a considerable fraction of the transfused RBCs that takes place within the first hours after transfusion; (2 minimizing the interaction of the transfused RBCs with the patient's immune system. These issues are important in reducing the number and extent of the damaging side effects of transfusions, such as generation of alloantibodies and autoantibodies and iron accumulation, especially in transfusion-dependent patients. Thus, it becomes important for blood bank research not only to assess the classical RBC parameters for quality control during storage, but even more so to identify the parameters that predict RBC survival, function and behaviour in the patient after transfusion. These parameters are likely to result from elucidation of the mechanisms that underly physiological RBC aging in vivo, and that lead to the generation of senescent cell antigens and the accumulation of damaged molecules in vesicles. Also, study of RBC pathology-related mechanisms, such as encountered in various hemoglobinopathies and membranopathies, may help to elucidate the mechanisms underlying a storage-associated increase in susceptibility to physiological stress conditions. Recent data indicate that a combination of new approaches in vitro to mimick RBC behaviour in vivo, the growing knowledge of the signaling networks that regulate RBC structure and function, and the rapidly expanding set of proteomic and metabolomic data, will be instrumental to identify the storage-associated processes that control RBC survival after transfusion.

    We report the successive stages of the reorganization of the blood transfusion sector in Togo. The starting point was the elaboration of the national policy of blood transfusion, then the adoption of a decree organizing the sector as well the various decree of application, particularly that related to transfusion good practices. The current policy recommends two poles of qualification of the blood ant its components and the creation of six stations of collection and distribution attached to these poles. The reorganization started with the rehabilitation of the National Blood Transfusion Centre (CNTS) in Lomé. If the problem of human resources is alarming, especially the availability of hemobiologists, the rehabilitation allowed the increase of the blood collection passing from 5272 donations in December 2003 to 18 164 in December 2008. However, the requirement of blood products is satisfied in 50% in all the country. In 2003, 24% of the blood products were rejected for positive viral markers against 8.37% in 2008 in relation with the improvement of blood safety. Efforts must be continued to reinforce it in the CNTS and to make a better selection of the donors at the Regional Blood Transfusion Centre (CRTS) de Sokodé. The analysis of the weak points of the sector (human resource insufficiency, shortage of the blood products, blood safety) made it possible to indicate solutions to improve the sector of blood transfusion sector. Future outcome is funded in the blood transfusion safety development project in Togo financed by the Agence française de développement (AFD, French development agency).

    Objective: Pakistan is a developing country where platelet concentrates are prepared and administered to patients in only a few large centres of the country. A study was designed for appraisal of the current situation and to review the progress made so far. Design: It was a prospective, non-interventional study. Place and duration of study: The study was conducted at PNS Shifa, Karachi from January, 1995 to December, 1998. Subjects and Methods: During this study 588 random donor platelet concentrates were transfused to 66 patients 148 occasions. Random donor platelet concentrates were prepared by fractionation of whole blood using triple blood collecting bags. Pre-transfusion and one hour posttransfusion platelet counts of the patients were done. The efficacy of the platelet transfusion was monitored by noting the clinical response as well as doing one hour posttransfusion corrected counts increment (CCI).Results: On 114 (77%) occasions platelets were transfused prophylactically and 34 (23%) times therapeutically to stop major bleeding episodes. The mean pre-transfusion platelet count varied from 15.5 x 10/sup 9/1 to 28.5 x 10/sup 9/l in different clinical conditions. On average, 4 random donor platelet concentrates were administered on each occasion. The best response was observed in patients of aplastic anaemia and worst in cases of disseminated intravascular coagulation (DIC). Conclusion: Platelet concentrates administration was inappropriate in significant number of patients, therefore, each hospital should form transfusion committee to review transfusion practices guidelines for blood components usage and compliance to these guidelines by the clinicians.

    Full Text Available Background: ABO incompatibility hemolytic disease of the newborn is a common cause of clinical jaundice and causes two-thirds of the hemolytic disease in newborns. This study was undertaken to determine the frequency of ABO incompatibility hemolytic disease and its complications in newborns undergoing exchange transfusion.Methods: This prospective and descriptive study was performed in jaundiced newborn infants during a three-year period. Inclusion criteria were: maternal blood type O, newborn blood type A or B, rising indirect hyperbilirubinemia in the first two days of life, positive immunohematologic test for newborns and exchange transfusion. Exclusion criteria were: incomplete information, other accompanying diseases that induce hyperbilirubinemia. All newborn infants received phototherapy before and after exchange transfusion. We did not use intravenous immunoglobulin, hemoxygenase inhibitor drugs and blood products before exchange transfusion.Results: Double-volume exchange transfusion via umbilical cord catheter was performed in 96 patients, 19 (20% of whom suffered from ABO incompatibility. Of these 19 newborns, two-thirds (13 were preterm infants. The minimum level of serum bilirubin was 10 mg/dl and the maximum serum bilirubin level was 35 mg/dl. In six patients (32% serum bilirubin levels were >25mg/dl. The most common blood group was type A for newborns. Immunohematologic tests were positive in 84% of the mothers. ABO incompatibility hemolytic disease was the fourth and second most common reasons for blood exchange transfusion in preterm and term infants, respectively. Laboratory complications were more common than clinical complications. The etiology of 48% of the alloimmunization and 42% of the hemolytic disease in these newborns was ABO incompatibility.Conclusions: Mothers with blood group O and newborns with blood group A or B with positive immunohematologic tests in first hours of life are at high risk for hemolytic disease

    In-utero transfusion is now well under control and improves the survival of foetuses monitored for fetal anemia with a survival rate of more than 80 %. The aim was to evaluate short-term neonatal outcome after fetal severe anemia managed by intrauterine transfusions. We did a retrospective study of all neonates born after management of severe fetal anemia (n = 93) between January 1999 and January 2013 in our regional center. The two main causes of anemia were maternal red blood cell alloimmunization (N = 81, 87 %) and Parvovirus B19 infection (N = 10, 10.8 %). In the alloimmunization group, phototherapy was implemented in 85.2 % of cases with a maximum level of bilirubin of 114.4 ± 60.7 (mg/dl). Transfusion and exchange transfusion were, respectively, required in 51.9 % and in 34.6 % of cases. One neonate presented a convulsive episode, and we observed three neonatal deaths. In the parvovirus group, none of the child had anemia at birth and no management was necessary. Contemporary management of Rhesus disease is associated with encouraging neonatal outcomes. In case of Parvovirus infection, no specific management is necessary at. But, in all cases of fetal anemia, children should be followed up with particular attention to neurologic development. • In-utero transfusion is now well under control and improves the survival of fetuses monitored for fetal anemia. • Limited studies are available on the effect of IUT on postnatal outcome in infants with a history of fetal anemia. What is New: • Contemporary management of severe Rhesus disease is associated with encouraging neonatal outcomes. • The majority of infants can be managed with phototherapy and a limited number of top-up transfusions and exchange transfusions. In case of Parvovirus infection, the short-term neonatal outcome is excellent.

    Full Text Available OBJECTIVES: Transfusion of allogeneic blood is still common in orthopedic surgery. This analysis evaluates from the perspective of a German hospital the potential cost savings of Epoetin alfa (EPO compared to predonated autologous blood transfusions or to a nobloodconservationstrategy (allogeneic blood transfusion strategyduring elective hip and knee replacement surgery. METHODS: Individual patients (N = 50,000 were simulated based on data from controlled trials, the German DRG institute (InEK and various publications and entered into a stochastic model (Monte-Carlo of three treatment arms: EPO, preoperative autologous donation and nobloodconservationstrategy. All three strategies lead to a different risk for an allogeneic blood transfusion. The model focused on the costs and events of the three different procedures. The costs were obtained from clinical trial databases, the German DRG system, patient records and medical publications: transfusion (allogeneic red blood cells: €320/unit and autologous red blood cells: €250/unit, pneumonia treatment (€5,000, and length of stay (€300/day. Probabilistic sensitivity analyses were performed to determine which factors had an influence on the model's clinical and cost outcomes. RESULTS: At acquisition costs of €200/40,000 IU EPO is cost saving compared to autologous blood donation, and cost-effective compared to a nobloodconservationstrategy. The results were most sensitive to the cost of EPO, blood units and hospital days. CONCLUSIONS: EPO might become an attractive blood conservation strategy for anemic patients at reasonable costs due to the reduction in allogeneic blood transfusions, in the modeled incidence of transfusion-associated pneumonia andthe prolongedlength of stay.

    Full Text Available Lesão pulmonar aguda associada à transfusão (transfusion-related acute lung injury, TRALI é uma complicação clínica grave relacionada à transfusão de hemocomponentes que contêm plasma. Recentemente, TRALI foi considerada a principal causa de morte associada à transfusão nos Estados Unidos e Reino Unido. É manifestada tipicamente por dispnéia, hipoxemia, hipotensão, febre e edema pulmonar não cardiogênico, que ocorre durante ou dentro de 6 h, após completada a transfusão. Embora o exato mecanismo não tenha sido totalmente elucidado, postula-se que TRALI esteja associada à infusão de anticorpos contra antígenos leucocitários (classes I ou II ou aloantígenos específicos de neutrófilos e a mediadores biologicamente ativos presentes em componentes celulares estocados. A maioria dos doadores implicados em casos da TRALI são mulheres multíparas. TRALI, além de ser pouco diagnosticada, pode ainda ser confundida com outras situações de insuficiência respiratória aguda. Um melhor conhecimento sobre TRALI pode ser crucial na prevenção e tratamento desta severa complicação transfusional.Transfusion-related acute lung injury (TRALI is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. Recently, TRALI has come to be recognized as the leading cause of transfusion-related death in the United States and United Kingdom. This complication typically presents as shortness of breath, hypoxemia, hypotension, fever and noncardiogeneic pulmonary edema, all occurring during or within 6 h after transfusion. Although the mechanism of TRALI has not been fully elucidated, it has been associated with human leukocyte antigen antibodies (class I, class II or neutrophil alloantigens and with biologically active mediators in stored cellular blood components. Most of the donors implicated in cases of TRALI are multiparous women. Rarely diagnosed, TRALI can be confused with other causes of acute

    Full Text Available BackgroundMany studies reported that copper, zinc and magnesium play important roles in the pathogenesis and development of neonatal hyperbilirubinemia. Exchange transfusion and intensive phototherapy are known two modalities of therapy for severe neonatal hyper bilirubinemia, but the effect of them on those trace elements is unknown.Materials and MethodsCopper, Zinc and Magnesium serum levels were measured before and after treatment with intensive phototherapy and exchange transfusion in full term neonates with indirect hyperbilirubinemia admitted to neonatal intensive care unit (NICU of Minia and Sohag University hospitals, Egypt, during 2014-2016 and comparison with normal healthy neonates was done.ResultsThere were significant higher copper and magnesium and lower zinc serum levels in neonates with indirect hyperbilirubinemia than controls before and after intensive phototherapy. These levels were significantly changed after exchange transfusion to be comparable with controls. Significant positive correlations between the total bilirubin levels and hemoglobin, copper, and magnesium serum levels and significant negative correlations with serum zinc levels were present. There were no significant correlations between maternal and neonatal copper, zinc or magnesium serum levels.ConclusionNeonates with indirect hyperbilirubinemia had significant higher copper and magnesium and lower zinc serum levels than healthy neonates which were not related to their maternal serum levels. Intensive phototherapy had no effect on their levels while exchange transfusion changed these levels to be comparable with that of normal healthy neonates.

    In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells. A 16-year-old with sickle cell disease receiving chronic transfusion of modified intensity (goal to maintain hemoglobin S<50%) who developed symptomatic anemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    Full Text Available Despite major advances in Brazilian blood transfusion therapy with a growing number of scientific publications, an increased number of repeat donors and a decline in serological ineligibility, a lack of conformity in the application of pre-transfusion tests that may compromise transfusion safety is still observed at transfusion agencies in the fringes of the blood transfusion therapy system. Additionally, although high rates of platelet transfusion refractoriness and significant rates of alloimmunization have been demonstrated in the international literature, few Brazilian centers have been concerned with the study of platelet alloimmunization and even fewer centers have evaluated the efficacy of platelet concentrate transfusion. As more than one million Brazilians, including many repeat blood donors, are listed in the National Bone Marrow Donor Registry (Redome, why not grant transfusion therapy services access to the HLA typing of these blood and marrow donors after obtaining their consent? And why not make use of the Redome data to evaluate the HLA compatibility of donors for alloimmunized patients who are candidates for bone marrow transfusion and who have already been typed? These measures, together with the identification of ABO and HPA antigens, will permit a complete assessment of platelet immunology, will guarantee the transfusion safety of this blood component, and will put Brazil at the same level as the so-called developed countries in terms of transfusion medicine.

    Full Text Available Transfusion transmitted infections are major problem associated with blood transfusion. Accurate estimates of risk of TTIs are essential for monitoring the safety of blood supply and evaluating the efficacy of currently employed screening procedures. The present study was carried out to assess the percentage of voluntary donors and replacement donors and to find out prevalence and changing trends of various TTIs blood donors in recent years. A study was carried out on blood units of voluntary and replacement donors which were collected from January 2008 to December 2012. On screening of 180,371 replacement units, seropositivity of transfusion transmitted disease in replacement donors was 0.15% in HIV, 1.67% in hepatitis B surface antigen, 0.49% in hepatitis C virus, 0.01% in VDRL, and 0.009% in malaria. Of 11,977 voluntary units, seropositivity of transfusion transmitted disease in voluntary donors was 0.08% in HIV, 0.24% in hepatitis B surface antigen, 0.001% in hepatitis C virus, 0.008% in VDRL (sexually transmitted disease, and 0.01% in malaria. From results it has been concluded that prevalence of transfusion transmitted infection (HIV, HBV, HCV, VDRL, and malaria was more in replacement donors in comparison to voluntary donors. Extensive donor selection and screening procedures will help in improving the blood safety.

    Blood saving strategies during paediatric spinal surgery often include recombinant erythropoietin (rEPO) and antifibrinolytic therapy (AFT). The goal of this study was to investigate additional preventive factors involved in the risk of blood transfusion. This prospective study was designed with the aim of identifying factors associated with the perioperative (defined as the intraoperative and the first postoperative day) probability of homologous red cell transfusion during scoliosis surgery in children operated during a one year period in our institution. The predictors analysed were: age, weight less than the 3rd percentile (W 255 minutes. ROC analysis for the latter model found an area under the curve of 0.9 (95% confidence interval: 0.8-0.97). The accuracy of the model was 92.3% (97.4% for non-transfusion and 69.2% for transfusion). Multivariate sensitivity analysis excluding patients with no preoperative administration of EPO found similar results. The current results indicate that optimising nutritional status might prevent allogenic blood transfusion and requires further investigation.

    Full Text Available Postnatal adaptation in preterm newborn comprises complex physiological processes that involve significant changes in the circulatory and respiratory system. Increasing hemoglobin level and blood volume following placental transfusion may be of importance in enhancing arterial oxygen content, increasing cardiac output, and improving oxygen delivery. The European consensus on resuscitation of preterm infants recommends delayed cord clamping (DCC for at least 60 s to promote placenta–fetal transfusion in uncompromised neonates. Recently, published meta-analyses suggest that DCC is associated with fewer infants requiring transfusions for anemia, a lower incidence of intraventricular hemorrhage, and lower risk for necrotizing enterocolitis. Umbilical cord milking (UCM has the potential to avoid some disadvantages associated with DCC including the increased risk of hypothermia or delay in commencing manual ventilation. UCM represents an active form of blood transfer from placenta to neonate and may have some advantages over DCC. Moreover, both methods are associated with improvement in hemodynamic parameters and blood pressure within first hours after delivery compared to immediate cord clamping. Placental transfusion appears to be beneficial for the preterm uncompromised infant. Further studies are needed to evaluate simultaneous placental transfusion with resuscitation of deteriorating neonates. It would be of great interest for future research to investigate advantages of this approach further and to assess its impact on neonatal outcomes, particularly in extremely preterm infants.

  5. The use of big data in transfusion medicine.

    'Big data' refers to the huge quantities of digital information now available that describe much of human activity. The science of data management and analysis is rapidly developing to enable organisations to convert data into useful information and knowledge. Electronic health records and new developments in Pathology Informatics now support the collection of 'big laboratory and clinical data', and these digital innovations are now being applied to transfusion medicine. To use big data effectively, we must address concerns about confidentiality and the need for a change in culture and practice, remove barriers to adopting common operating systems and data standards and ensure the safe and secure storage of sensitive personal information. In the UK, the aim is to formulate a single set of data and standards for communicating test results and so enable pathology data to contribute to national datasets. In transfusion, big data has been used for benchmarking, detection of transfusion-related complications, determining patterns of blood use and definition of blood order schedules for surgery. More generally, rapidly available information can monitor compliance with key performance indicators for patient blood management and inventory management leading to better patient care and reduced use of blood. The challenges of enabling reliable systems and analysis of big data and securing funding in the restrictive financial climate are formidable, but not insurmountable. The promise is that digital information will soon improve the implementation of best practice in transfusion medicine and patient blood management globally. © 2015 British Blood Transfusion Society.

    Postoperative anemia is frequent after revision of total knee arthroplasty (TKA) with reported transfusion rates up to 83%. Despite increased efforts of reducing blood loss and enhancing fast recovery within the fast-track setup, a considerable transfusion rate is still evident. The aim of this study was therefore to evaluate the effect of a bipolar sealer on blood loss and transfusion in revision TKA. In this single-center prospective cohort study with retrospective controls, 51 patients were enrolled in a fast-track setup for revision TKA without the use of a tourniquet. Twenty-five prospectively enrolled patients received treatment with both a bipolar sealer and electrocautery, whereas 26 patients had received treatment with a conventional electrocautery only in the retrospective group. No significant differences were found neither for calculated blood loss, with 1397 (standard deviation, ± 452) mL in the bipolar sealer group vs 1452 (SD, ± 530) mL in the control group (P = .66), nor for blood transfusion rates of 53% and 46% (P = .89), respectively. Four controls were readmitted within 90 days follow-up. The use of a bipolar sealer in a TKA revision setting without the use of a tourniquet did not reduce blood loss or blood transfusion rates.

    Correction of craniosynostosis can result in blood loss when the patient already has physiologic anemia. The aim of this study was to determine whether patients benefit from early blood transfusion and whether the timing of blood transfusion affects metabolic disturbances and the postoperative course. In this retrospective review, 71 patients who underwent open calvarial vault remodeling for correction of craniosynostosis were separated into 2 groups according to whether they received blood transfusions early (within the first 30 minutes of surgery) or later (after the first 30 minutes of surgery). Patients were further separated into nonsyndromic and syndromic cohorts. Tracked variables included hemoglobin, hematocrit, arterial blood gas values, lactate level, length of stay, estimated blood loss, and amount of blood transfused in the operating room, amount transfused postoperatively, and total amount transfused.Among all patients, the early transfusion group had a higher hemoglobin nadir overall and received less postoperative blood. Within the nonsyndromic cohort, the early transfusion group had a higher estimated blood loss and received more transfused blood. In the syndromic cohort, the early transfusion group had a hemoglobin nadir that was significantly higher than in the late transfusion group and a lower estimated blood loss, shorter pediatric intensive care unit stay, and less postoperative blood transfused. Syndromic patients also received significantly more blood overall. For syndromic patients undergoing open calvarial vault remodeling, transfusion within the first 30 minutes of surgery should be considered.

    We retrospectively examined intraoperative blood transfusion patterns at US veteran's hospitals through description of national patterns of intraoperative blood transfusion by indication for transfusion in the elderly; assessment of temporal trends in the use of intraoperative blood transfusion; and relationship of institutional use of intraoperative blood transfusion to hospital 30-day risk-adjusted postoperative mortality rates.Limited data exist on the pattern of intraoperative blood transfusion by indication for transfusion at the hospital level, and the relationship between intraoperative transfusion rates and institutional surgical outcomes.Using the Department of Veterans Affairs Surgical Quality Improvement Program database, we assigned 424,015 major noncardiac operations among elderly patients (≥65 years) in 117 veteran's hospitals, from 1997 to 2009, into groups based on indication for intraoperative blood transfusion according to literature and clinical guidelines. We then examined institutional variations and temporal trends in surgical blood use based on these indications, and the relationship between these institutional patterns of transfusion and 30-day postoperative mortality.Intraoperative transfusion occurred in 38,056/424,015 operations (9.0%). Among the 64,390 operations with an indication for transfusion, there was wide variation (median: 49.9%, range: 8.7%-76.2%) in hospital transfusion rates, a yearly decline in transfusion rates (average 1.0%/y), and an inverse relationship between hospital intraoperative transfusion rates and hospital 30-day risk-adjusted mortality (adjusted mortality of 9.8 ± 2.8% vs 8.3 ± 2.1% for lowest and highest tertiles of hospital transfusion rates, respectively, P = 0.02). In contrast, for the 225,782 operations with no indication for transfusion, there was little variation in hospital transfusion rates (median 0.7%, range: 0%-3.4%), no meaningful temporal change in transfusion (average 0.0%/y), and

    Transfusion of blood cell components is frequent in the therapeutic arsenal; it is globally safe or even very safe. At present, residual clinical manifestations are principally inflammatory in nature. If some rare clinical hazards manifest as acute inflammation symptoms of various origin, most of them linked with conflicting and undesirable biological material accompanying the therapeutic component (infectious pathogen, pathogenic antibody, unwanted antigen, or allergen), the general feature is subtler and less visible, and essentially consists of alloimmunization or febrile non-hemolytic transfusion reaction. The present essay aims to present updates in hematology and immunology that help understand how, when, and why subclinical inflammation underlies alloimmunization and circumstances characteristic of red blood cells and – even more frequently – platelets that contribute inflammatory mediators. Modern transfusion medicine makes sustained efforts to limit such inflammatory hazards; efforts can be successful only if one has a clear view of each element’s role. PMID:27965664

    A safe supply of blood and the knowledge, skill, and resources for the appropriate use of blood are essential for medical services. Many problems are faced in the development of transfusion services in low- or medium-income countries (LMICs). Unfortunately, in many countries, providing safe blood is made more difficult by a lack of blood donors and the high frequency of transfusion-transmissible infections. The problems are compounded by the frequent need for urgent life-saving transfusions. This article examines the problems in supply, safety, and use of blood and how they are being addressed in LMICs, predominantly focusing on sub-Saharan Africa. Copyright © 2016 Elsevier Inc.

    The use of blood transfusion in cardiac surgery varies widely. The beneficial effects of blood products are offset by an increase in morbidity and mortality. Despite multiple studies showing an association between blood product exposure and adverse short- and long-term events, it is difficult to determine causality. Nevertheless, the implication is sufficient to warrant the search for alternative strategies to reduce the use of blood products while providing a standard of care that optimizes postoperative outcomes. Aortic surgery, in particular, is associated with an increased risk of bleeding requiring a blood transfusion. There is a paucity of evidence within aortic surgery regarding the deleterious effects of blood products. Here, we review the current evidence regarding patient outcomes after blood transfusion in cardiac surgery, with special emphasis on aortic surgery.

    We summarize the pathology of the transfusion associated graft versus host disease (TA-GVHD) and examine the usefulness of the blood irradiation before transfusion as more widely used prophylaxis. The symptom of TA-GVHD was as follows: after (asymptomatic phase) for 1 to 2 weeks after blood transfusion, pyrexia and erythema appeared. Furthermore, hepatic disorder, diarrhea and bloody stool occurred. In no longer time, pancytopenia by aplastic crisis of the bone marrow appeard, and severe granulocytopenia occurred. Finally, by the complication with severe infectious disease such as septicemia, almost all the patients died with in 3 to 4 weeks after blood transfusion. TA-GVHD was found in some patients without immune deficiency syndrome. The cause of the frequent occurrence of the disease in Japan was shown by the probability of the one-way matching analysis. As the countermeasure of TA-GVHD, we examined the effectiveness of the blood irradiation before transfusion under the consideration of the safety and the emergency. After the responder cells were beforehand irradiated with various doses of radiation (X-ray or g-ray), the proliferative response was investigated through the uptake of 3 H-thymidine, and we obtained 15-50 Gy as the optimum dose of the radiation. We discuss the establishment of the countermeasure for the TA-GVHD and the formation of the nationwide support system for TV-GVHD (K.H.). 33 refs

    The management of a pregnant woman with the rare Ko phenotype and anti-Ku is a special challenge, because matched blood is extremely rare and the possibility of severe hemolytic disease of the newborn is high. A 30-year-old woman with rare Ko (Knull) phenotype presented at 18 weeks of gestation with positive indirect agglutination test results. She had anti-Ku due to previous blood transfusion, one pregnancy, and two abortions. During this pregnancy, anti-Ku titers ranged from 1024 to 4096. At the 26th week of gestation ultrasound showed a hydropic fetus and urgent intrauterine exchange transfusion was performed with the maternal red blood cells (RBCs). Recombinant human erythropoietin (rHu-EPO) and intravenous (IV) iron were administered to the mother to ensure an adequate supply of matched RBCs for intrauterine transfusions and possible perinatal hemorrhage. Intrauterine transfusions were repeated every 1 to 3 weeks. By 35 weeks 2 days of gestation, the mother had donated 4 units of blood, and four intrauterine transfusions had been performed. Cesarean section was then decided and a healthy male newborn was born. He was treated with phototherapy but without exchange transfusions. By the 15th day of life rHu-EPO was administrated to the newborn because of anemia. The maternal RBCs completely disappeared from the child's blood by Day 100. As shown in this case, treatment with rHu-EPO and IV Fe has effectively increased the mother's capacity to donate RBCs for autologous use and intrauterine transfusions, with no adverse effects to the mother or the child.

    The combined effects of balanced transfusion ratios and use of procoagulant and antifibrinolytic therapies on trauma-induced exsanguination are not known. The aim of this study was to investigate the combined effect of transfusion ratios, tranexamic acid and products containing fibrinogen on the outcome of injured patients with bleeding. A prospective multicentre observational study was performed in six level 1 trauma centres. Injured patients who received at least 4 units of red blood cells (RBCs) were analysed and divided into groups receiving a low (less than 1 : 1) or high (1 or more : 1) ratio of plasma or platelets to RBCs, and in receipt or not of tranexamic acid or fibrinogen products (fibrinogen concentrates or cryoprecipitate). Logistic regression models were used to assess the effect of transfusion strategies on the outcomes 'alive and free from massive transfusion' (at least 10 units of RBCs in 24 h) and early 'normalization of coagulopathy' (defined as an international normalized ratio of 1·2 or less). A total of 385 injured patients with ongoing bleeding were included in the study. Strategies that were independently associated with an increased number of patients alive and without massive transfusion were a high platelet to RBC ratio (odds ratio (OR) 2·67, 95 per cent c.i. 1·24 to 5·77; P = 0·012), a high plasma to RBC ratio (OR 2·07, 1·03 to 4·13; P = 0·040) and treatment with tranexamic acid (OR 2·71, 1·29 to 5·71; P = 0·009). No strategies were associated with correction of coagulopathy. A high platelet or plasma to RBC ratio, and use of tranexamic acid were associated with a decreased need for massive transfusion and increased survival in injured patients with bleeding. Early normalization of coagulopathy was not seen for any transfusion ratio, or for use of tranexamic acid or fibrinogen products. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Transfusion of packed red blood cells (PRBCs) is associated with an increased incidence of nosocomial infections and an increased risk of death. The duration of storage before transfusion may influence these outcomes. Here, we explore the association between the age of transfused PRBCs and specific patterns of inflammatory gene expression in severely injured trauma patients. Severely injured trauma patients requiring intensive care unit treatment and receiving transfusion of PRBCs within 24 hours of the injury were recruited. Blood samples were obtained within 2 hours of the trauma, at 24 hours, and at 72 hours. Messenger RNA was extracted from whole blood, and gene expression was quantified using quantitative polymerase chain reaction. The median age of the units of PRBCs transfused to each patient was recorded. The primary outcome measure was the change in candidate gene expression over the initial 72 hours. Sixty-four patients were studied. Fifty-three patients (83%) were male, and the median age was 40.5 years (interquartile range [IQR], 31-59). Median Injury Severity Score (ISS) was 31.5 (IQR, 23-43), and 55 patients (86%) experienced a blunt injury. Forty-one patients (64%) developed a nosocomial infection, and 15 patients (23%) died before hospital discharge. Each patient received a median of 5 U of PRBCs (IQR, 4-9.8 U) during the first 24 hours of hospital admission. The median age of the units of PRBCs transfused in each patient was 20 days (IQR, 17-22 days). Older blood was associated with greater decreases in interleukin 12 (IL-12), IL-23, and RORγt (all p's < 0.05) gene expression over the initial 24 hours, greater decreases in IL-12 gene expression over 72 hours, and a rise in transforming growth factor β gene expression over the first 72 hours. A multivariate analysis confirmed the independence of these associations. Increasing the duration of storage of PRBCs before transfusion is associated with a pattern of gene expression consistent with more

    Plasma transfusions are given to patients with coagulopathy, either prophylactically, before an invasive procedure; or therapeutically, in the presence of active bleeding; and as an exchange fluid in therapeutic plasma exchange for disorders such as thrombotic thrombocytopenic purpura. There is consensus that many prophylactic plasma transfusions are non-efficacious, and the misdiagnosis of thrombotic thrombocytopenic purpura results in unnecessary therapeutic plasma exchange. Beginning in 2001, programs to reduce plasma transfusion in the three major teaching hospitals in Rhode Island were initiated. The programs evolved through the establishment of guidelines, education for key prescribers of plasma, screening of plasma prescriptions, and engagement of individual prescribing physicians for out-of-guidelines prescriptions with modification or cancellation. Establishment of an in-house ADAMTS13 (ADAM metallopeptidase with thrombospondin type 1, motif 13) assay in 2013 was used to prevent therapeutic plasma exchange in patients with non-thrombotic thrombocytopenic purpura microangiopathy. Transfusion service data were gathered at the hospital level regarding blood component use, hospital data for discharges, inpatient mortality, and mean case-mix index, and, at the state level, for units of plasma shipped from the community blood center to in-state hospitals. Between 2006 and 2016, a reduction in plasma use from 11,805 to 2677 units (a 77% decrease) was observed in the three hospitals and was mirrored in the state as a whole. This decline was not associated with any increase in red blood cell transfusion. Inpatient mortality either declined or was unchanged. An active program focused on education and interdiction can achieve a large decrease in plasma transfusions without evidence of patient harm. © 2017 AABB.

    Implementation of quality system improvement at the Blood Transfusion Institute Novi Sad, included adjustments in practice to the request of ISO 9001 standard. Quality improvement must be a permanent activity of the Institute. The audit is a management tool for monitoring the quality assurance system and is either a quality audit or a medical audit. A well planned, comprehensive quality audit covers each activity of the Blood Transfusion Institute. The procedures may be internal or external. Quality manager is responsible for annual internal quality audits. The purpose of internal audits is to check the efficiency of the quality system in terms of realization of quality policy, fulfullment of designed targets and implementation of quality system documents. An internal quality audit is performed in accordance with the procedure and audit findings are reported to the management in a form of internal quality report as a part of quality system review. The findings must be communicated to all persons responsible for the controlled area. Quality manager can initiate an internal quality audit whenever it is realized that problems about the quality system have occurred. Audits are conducted by the quality manager or an audit team. The accurate list of internal auditors is kept in the Institute archive. Medical audit carried out by a transfusion committee, evaluates the quality of blood transfusion for determining the degree of compliance with established local or national guidelines, in order to promote optimal transfusion practice. Audits are not only used for determining further quality management activities, but also make basis for creating and maintenance of excellent relations with product and service users. Considering all this, Blood Transfusion Institute exceeds the requirements of ISO 9000 standards series.

    This study was purposed to explore the suitable ratio between fresh frozen plasma and erythrocyte by retrospective analysis of coagulation in patients with massive blood transfusion. The clinical data of 151 cases with massive blood transfusion from January 2011 to January 2013 were analyzed retrospectively. According to coagulation, patients were divided into coagulation normal group (138 cases) and coagulation dysfunction group (13 cases). Based on the ratio of 1:1 of fresh frozen plasma and erythrocyte, the patients were divided into high plasma group(2:1), medium plasma group (1:1) and low plasma (blood transfusion. The results showed that prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) were prolonged, fibrinogen (FIB) level decreased significantly (all P blood transfusion 24 h; the high plasma and the medium plasma group of coagulation normal group had no significant changes in coagulation (P > 0.05); prothrombin time, activated partial thromboplastin time, thrombin time and fibrinogen level in the medium plasma and low plasma subgroup of coagulation dysfunction group after massive transfusion was still in abnormal levels (P > 0.05), coagulation function in high plasma subgroup was improved significantly (P blood transfusion, the ratio between fresh frozen plasma and erythrocyte is recommended to be 2:1 in patients of coagulation dysfunction in order to improve the patient's coagulation function and to reduce the incidence of adverse event, the ratio of fresh frozen plasma to erythrocyte is recommended to be 1:1 in patients with normal coagulation so as to reduce the dilutional coagulopathy and hypervolemia of blood.

    A blood transfusion is an acute intervention, used to address life- and health-threatening conditions on a short-term basis. Packed red blood cells are most often used for blood transfusion. Sometimes blood is transfused after prolonged storage but there is continuing debate as to whether transfusion of 'older' blood is as beneficial as transfusion of 'fresher' blood. To assess the clinical benefits and harms of prolonged storage of packed red blood cells, in comparison with fresh, on recipients of blood transfusion. We ran the search on 1st May 2014. We searched the Cochrane Injuries Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE (OvidSP), Embase (OvidSP), CINAHL (EBSCO Host) and two other databases. We also searched clinical trials registers and screened reference lists of the retrieved publications and reviews. We updated this search in June 2015 but these results have not yet been incorporated. Randomised clinical trials including participants assessed as requiring red blood cell transfusion were eligible for inclusion. Prolonged storage was defined as red blood cells stored for ≥ 21 days in a blood bank. We did not apply limits regarding the duration of follow-up, or country where the study took place. We excluded trials where patients received a combination of short- and long-stored blood products, and also trials without a clear definition of prolonged storage. We independently performed study selection, risk of bias assessment and data extraction by at least two review authors. The major outcomes were death from any cause, transfusion-related acute lung injury, and adverse events. We estimated relative risk for dichotomous outcomes. We measured statistical heterogeneity using I(2). We used a random-effects model to synthesise the findings. We identified three randomised clinical trials, involving a total of 120 participants, comparing packed red blood cells with ≥ 21 days storage

  2. Transfusions of blood and blood products and viral infections

    Full Text Available Transfusions of blood and blood products are commonly used in medicine, but being biological materials they carry a risk of transmitting infections--viral, bacterial, parasitic, as well as prions. Laboratory tests used for screening of donated blood for viral infections at present cannot detect all infectious units. Criteria for selection of blood donors therefore must be very strict, while methods of inactivation of viruses and laboratory assays for detection of their presence must be improved. Indications for blood transfusion should be restricted.

    As a therapy or a support to other therapies, despite being largely beneficial to patients in general, transfusion it is not devoid of some risks. In a moderate number of cases, patients may manifest adverse reactions, otherwise referred to as transfusion-associated hazards (TAHs). The latest French 2016 haemovigilance report indicates that 93% of TAHs are minor (grade 1), 5.5% are moderate (grade 2) and 1.6% are severe (grade 3), with only five deaths (grade 4) being attributed to transfusion with relative certainty (imputability of level [or grade] 1 to 3). Health-care providers need to be well aware of the benefits and potential risks (to best evaluate and discuss the benefit-risk ratio), how to prevent TAHs, the overall costs and the availability of alternative therapeutic options. In high-income countries, most blood establishments (BEs) and hospital blood banks (HBBs) have developed tools for reporting and analysing at least severe transfusion reactions. With nearly two decades of haemovigilance, transfusion reaction databases should be quite informative, though there are four main caveats that prevent it from being fully efficient: (ai) reporting is mainly declarative and is thus barely exhaustive even in countries where it is mandatory by law; (aii) it is often difficult to differentiate between the different complications related to transfusion, diseases, comorbidities and other types of therapies in patients suffering from debilitating conditions; (aiii) there is a lack of consistency in the definitions used to describe and report some transfusion reactions, their severity and their likelihood of being related to transfusion; and (aiv) it is difficult to assess the imputability of a particular BC given to a patient who has previously received many BCs over a relatively short period of time. When compiling all available information published so far, it appears that TAHs can be analysed using different approaches: (bi) their pathophysiological nature; (bii

    Full Text Available Background: Serological safety is an integral part of overall safety for blood banks. Emphasis is on the use of routinue Red Blood Cell (RBC antibody screen test, at set time intervals, to reduce risks related to alloantibodies. Also emphasis is on importance of issuing antigen negative blood to alloantibody positive patients. Effect of using leucodepleted blood on the rate of alloimmunization is highlighted. The concept of provision of phenotypically matched blood is suggested. Materials and Methods: Antibody screen test is important to select appropriate blood for transfusion. Repeat antibody screen testing, except if time interval between the earlier and subsequent transfusion was less than 72 hours, followed by antibody identification, if required, was performed in patients being treated with repeat multiple blood transfusions. Between February 2008 and June 2009, repeat samples of 306 multi-transfused patients were analyzed. Search for irregular antibodies and reading of results was conducted using RBC panels (three-cell panel of Column Agglutination Technology (CAT and two cell panel of the Solid Phase Red Cell Adherence Technology (SPRCAT. Specificities of antibodies were investigated using appropriate panels, 11 cell panel of CAT and 16 cell panel of SPRCA. These technologies, detecting agglutination in columns and reactions in solid phase, evaluate the attachment of irregular incomplete antibody to antigen in the first phase of immunological reaction more directly and hence improve the reading of agglutination. Three to four log leuco reduced red blood cells were transfused to patients in the study using blood collection bags with integral filters. Results: Alloimmunization rate of 4.24% was detected from 306 multiply transfused patients tested and followed up. The Transfusion therapy may become significantly complicated. Conclusion: Red cell antibody screening and identification and subsequent issue of antigen negative blood have a

  5. Neonatal Platelet Transfusions and Future Areas of Research.

    Thrombocytopenia affects approximately one fourth of neonates admitted to neonatal intensive care units, and prophylactic platelet transfusions are commonly administered to reduce bleeding risk. However, there are few evidence-based guidelines to inform clinicians' decision-making process. Developmental differences in hemostasis and differences in underlying disease processes make it difficult to apply platelet transfusion practices from other patient populations to neonates. Thrombocytopenia is a risk factor for common preterm complications such as intraventricular hemorrhage; however, a causal link has not been established, and platelet transfusions have not been shown to reduce risk of developing intraventricular hemorrhage. Platelet count frequently drives the decision of whether to transfuse platelets, although there is little evidence to demonstrate what a safe platelet nadir is in preterm neonates. Current clinical assays of platelet function often require large sample volumes and are not valid in the setting of thrombocytopenia; however, evaluation of platelet function and/or global hemostasis may aid in the identification of neonates who are at the highest risk of bleeding. Although platelets' primary role is in establishing hemostasis, platelets also carry pro- and antiangiogenic factors in their granules. Aberrant angiogenesis underpins common complications of prematurity including intraventricular hemorrhage and retinopathy of prematurity. In addition, platelets play an important role in host immune defenses. Infectious and inflammatory conditions such as sepsis and necrotizing enterocolitis are commonly associated with late-onset thrombocytopenia in neonates. Severity of thrombocytopenia is correlated with mortality risk. The nature of this association is unclear, but preclinical data suggest that thrombocytopenia contributes to mortality rather than simply being a proxy for disease severity. Neonates are a distinct patient population in whom

    Although blood transfusion is a lifesaving therapy for some patients, transfusion has been named 1 of the top 5 overused procedures in US hospitals. As unnecessary transfusions only increase risk and cost without providing benefit, improving transfusion practice is an effective way of promoting high-value care. Most high-quality clinical trials supporting a restrictive transfusion strategy have been published in the past 5 to 10 years, so the value of a successful patient blood management program has only recently been recognized. We review the most recent transfusion practice guidelines and the evidence supporting these guidelines. We also discuss several medical societies' Choosing Wisely campaigns to reduce or eliminate overuse of transfusions. A blueprint is presented for developing a patient blood management program, which includes discussion of specific methods for optimizing transfusion practice.

    To assess the 30-day and 1-year mortality associated to the red blood cell transfusion after coronary artery bypass grafting surgery. This procedure has been questioned by the international medical community, but it is still widely used in cardiac surgery. Therefore, it is needed more evidence of this medical practice in our country. We retrospectively analyzed 3,004 patients who underwent coronary artery bypass grafting surgery between June 2009 and July 2010. Patients were divided into two groups: non-transfused and transfused. The transfused group totaled 1,888 (63%) and non-transfused 1,116 (37%). There were 129 deaths in 30 days, with 108 (84%) in the transfused group and 21 (16%) in the non-transfused (Pconservation strategies should be encouraged to reduce blood products transfusions.

    We estimated rates for common plasma-associated transfusion reactions and compared reported rates for various plasma types. We performed a systematic review and meta-analysis of peer-reviewed articles that reported plasma transfusion reaction rates. Random-effects pooled rates were calculated and compared between plasma types. Meta-regression was used to compare various plasma types with regard to their reported plasma transfusion reaction rates. Forty-eight studies reported transfusion reaction rates for fresh-frozen plasma (FFP; mixed-sex and male-only), amotosalen INTERCEPT FFP, methylene blue-treated FFP, and solvent/detergent-treated pooled plasma. Random-effects pooled average rates for FFP were: allergic reactions, 92/10 5 units transfused (95% confidence interval [CI], 46-184/10 5 units transfused); febrile nonhemolytic transfusion reactions (FNHTRs), 12/10 5 units transfused (95% CI, 7-22/10 5 units transfused); transfusion-associated circulatory overload (TACO), 6/10 5 units transfused (95% CI, 1-30/10 5 units transfused); transfusion-related acute lung injury (TRALI), 1.8/10 5 units transfused (95% CI, 1.2-2.7/10 5 units transfused); and anaphylactic reactions, 0.8/10 5 units transfused (95% CI, 0-45.7/10 5 units transfused). Risk differences between plasma types were not significant for allergic reactions, TACO, or anaphylactic reactions. Methylene blue-treated FFP led to fewer FNHTRs than FFP (risk difference = -15.3 FNHTRs/10 5 units transfused; 95% CI, -24.7 to -7.1 reactions/10 5 units transfused); and male-only FFP led to fewer cases of TRALI than mixed-sex FFP (risk difference = -0.74 TRALI/10 5 units transfused; 95% CI, -2.42 to -0.42 injuries/10 5 units transfused). Meta-regression demonstrates that the rate of FNHTRs is lower for methylene blue-treated compared with FFP, and the rate of TRALI is lower for male-only than for mixed-sex FFP; whereas no significant differences are observed between plasma types for allergic reactions, TACO

    1992-01-01

    Thirty frequently transfused patients on long term hemodialysis were studied and a similar number of age and sex-matched patients who were infrequently transfused were used as a control group to ascertain the influence of a previous myocardial infarction (MI) on transfusion requirements. The frequency of previous MI on electrocardiogram (ECG) in the transfused and control groups was similar (40 percent and 37 percent, respectively). In frequently transfused dialysis patients with MI, the hemoglobin level (transfusion trigger) at which these patients were transfused was higher than that of frequently transfused patients without MI (8.3 +/- 1.5 g per dl vs. 6.9 +/- 1 g per dl, p less than 0.01) which indicated that patients without MI tolerated a greater degree of anemia than those with MI. The 2,3-diphosphoglycerate (2,3-DPG) levels were significantly elevated in all transfused patients when compared to matched controls. However, levels of 2,3-DPG were significantly higher in MI patients receiving frequent transfusions than in other transfused patients, suggesting oxygen demands may not have been fully met despite the frequent transfusions. The results suggest levels of 2,3-DPG deserve further study in relation to the adequacy of tissue oxygenation in anemic dialysis patients.

As an example, fresh whole blood in large-volume hemorrhage may be superior to whole blood reconstituted from multiple components. Multicomponent apheresis can overcome logistical difficulties in matching patient needs with fresh component availability and can deliver the benefits of fresh whole blood. Because of the different transfusion needs of patients in emerging economies and the vulnerability of these blood systems to emerging infections, fresh whole blood and multicomponent apheresis can better meet patient needs when compared with transplants of the "manufacturing paradigm". We propose that patient blood management, along with panels of repeat, paid, accredited apheresis and fresh whole-blood donors can be used in emerging economies to support decentralized blood services. This alternative transfusion–medicine paradigm could eventually also be adopted by established economies to focus transfusion medicine on local patient needs and to alleviate the problem of the aging volunteer donor base.Keywords: indications, emerging countries, patient blood management

    2017-08-01

    To curtail inappropriate plasma transfusions, we instituted clinical decision support as an alert upon order entry if the patient's recent international normalized ratio (INR) was 1.7 or less. The alert was suppressed for massive transfusion and within operative or apheresis settings. The plasma order was automatically removed upon alert acceptance while clinical exception reasons allowed for continued transfusion. Alert impact was studied comparing a 7-month control period with a 4-month intervention period. Monthly plasma utilization decreased 17.4%, from a mean ± SD of 3.40 ± 0.48 to 2.82 ± 0.6 plasma units per hundred patient days (95% confidence interval [CI] of difference, -0.1 to 1.3). Plasma transfused below an INR of 1.7 or less decreased from 47.6% to 41.6% (P = .0002; odds ratio, 0.78; 95% CI, 0.69-0.89). The alert recommendation was accepted 33% of the time while clinical exceptions were chosen in the remaining cases (active bleeding, 31%; other clinical indication, 33%; and apheresis, 2%). Alert acceptance rate varied significantly among different provider specialties. Clinical decision support can help curtail inappropriate plasma use but needs to be part of a comprehensive strategy including audit and feedback for comprehensive, long-term changes. © American Society for Clinical Pathology, 2017.

    2017-09-01

    Advances in serology and viral nucleic acid testing (NAT) over the last decades significantly reduced the risk of transfusion-transmitted hepatitis B virus (HBV). The combination of HBsAg testing and NAT efficiently prevents the majority of HBV transmission. However, a specific residual risk remains associated with extremely low viral DNA levels in blood donors with occult HBV infection (OBI) that are intermittently or not detectable even by highly sensitive individual donation (ID) NAT. Studies have reported HBV transfusion-transmission with blood components from donors with OBI that contained low amount of viruses (transfusion-transmission seems to depend on a combination of several factors including the volume of plasma associated with the infected blood components transfused, the anti-HBV immune status of both recipient and donor, and possibly the viral fitness of the infecting HBV strain. Models based on clinical and experimental evidences estimate a residual transmission risk of 3-14% associated with OBI donations testing HBsAg and ID-NAT non-reactive. Anti-HBc testing has the potential to improve further blood safety but it may also compromise blood availability in settings with medium/high HBV prevalence. Pathogen reduction procedures might be considered. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    2010-01-01

    Full Text Available The beta-globin gene mutation in sickle cell anemia results in anemia and repeated bouts of vascular occlusion. The cumulative effect of these vasocclusive events is progressive damage to many organs including the kidneys, lungs, and brain. The transfusion of red blood cells (RBC can ameliorate many of these complications, but can be associated with both acute and chronic complications, including iron overload. The objective of the Best Practices in Transfusion Medicine for Patients with Sickle Cell Disease (SCD Conference was to review the available published evidence and clinical experience surrounding the use of RBC transfusions for sickle cell disease by a panel of experts. The expert panel developed explicit clinical guidelines for the use of RBC in SCD patients. The panel also made recommendations for further research.  A set of guidelines were produced for dissemination to pertinent stakeholders. If implemented, these clinical pathways have the potential to optimize the use of red blood cell transfusions in SCD.

    Non-transfusion-dependent thalassemias (NTDT) encompass a group of hereditary chronic hemolytic anemia, which, as the name indicates, not require regular blood transfusion for survival. These include β-thalassemia intermedia, hemoglobin E/β-thalassemia, and Hemoglobin H disease (α- thalassemia intermedia). Individuals with structural variant of hemoglobin especially Hemoglobin S and Hemoglobin C associated with "α" or "β" thalassemia in heterozygous condition may also present with similar features of NTDT. NTDT patients are not immune to the development of transfusion unrelated complications in the long run. These hereditary chronic hemolytic anemias are still under-recognized in developing countries like India, where the disease burden might be high causing significant morbidity. The pathophysiologic hallmark that characterizes this group of disorders (ineffective erythropoiesis, hemolysis, chronic anemia) leads to a number of serious complications, similar to transfusion dependent thalassemia. So, timely diagnosis and institution of appropriate preventive/remedial measures as well as education of patient population can help decrease the morbidity to a significant extent. In the present review, focus will be on the pathophysiological mechanisms and available management options of NTDT from a developing country perspective like India.

    Thalassaemia major patients require lifelong transfusion support due to which they are prone for alloimmunization to foreign RBCs. Alloimmunization can be prevented by extended phenotype match blood transfusion. The study was conducted to know the extent of problem of alloimmunization and to find important red cell antibodies in thalassaemia patients. A cross-sectional study was conducted. A total of 32 thalassaemia patients were enrolled. The specimen was subjected to red cell alloantibody and autoantibody by column gel agglutination technique. R 1 (w) R 1 , R 2 R 2 , rr (papaine and non papain) and 11 cell panel reagent cells were used in screening and identification of alloantibodies respectively. Six (18.8 %) subjects were alloimmunized. All alloimmunized subjects were recipient of more than 20 units of transfusion. Total seven clinically significant alloantibodies were identified. Anti E and anti c were commonest antibodies in four (12.5%) patients. Red cell alloimmunization is an important risk in thalassaemia patient. 71.4% of alloantibodies were anti E and anti c type. Extended phenotype match blood transfusion for Rh-c and Rh-E antigens or level 2 antigen matching stringency needs to be explored in preventing alloimmunization in thalassaemia patients.

    Anaemia is a common condition among patients admitted to hospital medicosurgical departments, as well as in critically ill patients. Anaemia is more frequently due to absolute iron deficiency (e.g. chronic blood loss) or functional iron deficiency (e.g. chronic inflammatory states), with other causes being less frequent. In addition, preoperative anaemia is one of the major predictive factors for perioperative blood transfusion. In surgical patients, postoperative anaemia is mainly caused by perioperative blood loss, and it might be aggravated by inflammation-induced inhibition of erythropoietin and functional iron deficiency (a condition that cannot be corrected by the administration of oral iron). All these mechanisms may be involved in the anaemia of the critically ill. Intravenous iron administration seems to be safe, as very few severe side-effects were observed, and may result in hastened recovery from anaemia and lower transfusion requirements. However, it is noteworthy that many of the recommendations given for intravenous iron treatment are not supported by a high level of evidence and this must be borne in mind when making decisions regarding its application to a particular patient. Nonetheless, this also indicates the need for further large, randomized controlled trials on the safety and efficacy of intravenous iron for the treatment of anaemia in different clinical settings.

    Full Text Available Karim Bayanzay, Lama Alzoebie Department of Hematology, Gulf Medical University, Ajman, United Arab Emirates Abstract: Hypertransfusion regimens for thalassemic patients revolutionized the management of severe thalassemia; transforming a disease which previously led to early infant death into a chronic condition. The devastating effect of the accrued iron from chronic blood transfusions necessitates a more finely tuned approach to limit the complications of the disease, as well as its treatment. A comprehensive approach including carefully tailored transfusion protocol, continuous monitoring and assessment of total body iron levels, and iron chelation are currently the mainstay in treating iron overload. There are also indications for ancillary treatments, such as splenectomy and fetal hemoglobin induction. The main cause of death in iron overload continues to be related to cardiac complications. However, since the widespread use of iron chelation started in the 1970s, there has been a general improvement in survival in these patients.

    Background Prevalence estimates of serious hazards of transfusion vary widely. We hypothesized that the current reporting infrastructure in the United States fails to capture many transfusion reactions, and undertook a multi-center study utilizing active surveillance, data review, and adjudication to test this hypothesis. Study Design and Methods A retrospective record review was completed for a random sample of 17% of all inpatient transfusion episodes over 6 months at 4 academic tertiary care hospitals, with an episode defined as all blood products released to a patient in 6 hours. Data were recorded by trained clinical research nurses, and serious reactions were adjudicated by a panel of transfusion medicine experts. Results Of 4857 transfusion episodes investigated, 1.1% were associated with a serious reaction. Transfusion associated circulatory overload (TACO) was the most frequent serious reaction noted, being identified in 1% of transfusion episodes. Despite clinical notes describing a potential transfusion association in 59% of these cases, only 5.1% were reported to the transfusion service. Suspected transfusion related acute lung injury (TRALI/possible TRALI), anaphylactic, and hypotensive reactions were noted in 0.08%, 0.02%, and 0.02% of transfusion episodes. Minor reactions, including febrile non-hemolytic and allergic, were noted in 0.62% and 0.29% of transfusion episodes, with 30–50% reported to the transfusion service. Conclusion Underreporting of cardiopulmonary transfusion reactions is striking among academic, tertiary care hospitals. Complete and accurate reporting is essential to identify, define, establish pathogenesis, and mitigate/treat transfusion reactions. A better understanding of the failure to report may improve the accuracy of passive reporting systems. PMID:27460200

    Blood loss and replacement is still a controversial issue in major orthopaedic surgery. Allogenic blood transfusion may cause legal problems and concerns regarding the transmission of transfusion-related diseases. Cellsaver Systems (CSS) were developed as an alternative to allogenic transfusion but CSS transfusion may cause coagulation, infection and haemodynamic instability. Our aim was to analyse the efficiency and cost analysis of a cell saver auto-transfusion system in the total knee arthroplasty procedure. Retrospective comparative study. Those patients who were operated on by unilateral, cemented total knee arthroplasty (TKA) were retrospectively evaluated. Group 1 included 37 patients who were treated using the cell saver system, and Group 2 involved 39 patients who were treated by allogenic blood transfusion. The groups were compared in terms of preoperative haemoglobin and haematocrit levels, blood loss and transfusion amount, whether allogenic transfusion was made, degree of deformity, body mass index and cost. No significant results could be obtained in the statistical comparisons made in terms of the demographic properties, deformity properties, preoperative laboratory values, transfusion amount and length of hospital stay of the groups. Average blood loss was calculated to be less in Group 1 (pblood transfusion and costs more. Therefore, the routine usage of the auto-transfusion systems is a controversial issue. Cell saver system usage does not affect allogenic blood transfusion incidence or allogenic blood transfusion volume. It was found that preoperative haemoglobin and body mass index rates may affect allogenic blood transfusion. Therefore, it is foreseen that auto-transfusion systems could be useful in patients with low haemoglobin level and body mass index.
