    Full Text Available Objective: Hyperbilirubinemia is a common problem ofneonatal period that has high morbidity and mortality.Blood exchange is the most effective and urgent treatmentmodality for very high bilirubin levels that can lead toneurotoxicity called as kernicterus. The aim of this studywas to compare 90 minutes exchange transfusion withthat of 120 minutes.Methods: This study was performed at Dicle UniversityMedical Faculty, Neonatal Unit between July 2007 andJune 2008. A total of 36 term newborn (38 - 42 gestationalweek without blood group incompatibility and withtotal serum bilirubin levels over 25 mg/dl were included.Newborns were randomly assigned in two groups eachof them comprise 18 babies as Group 1 underwent 90minute-exchange and Group 2 120 minute. Effectivenessand complications of exchange transfusion were recorded.Newborns with Rh, ABO or subgroup incompatibilities,prematurity or small for gestational age, septicemia,hypothyroidism, G6PD enzyme deficiency, intrauterineinfections, diabetic mother’s baby, hemolytic disease ormetabolic diseases were excluded.Results: There were no significant differences in thebody weight, gestational age, postnatal age, age of mother,total bilirubin and albumin levels, the number of bloodexchange, hospital stay days and complications betweentwo groups (p>0.05. However, mean phototherapy durationwas significantly shorter in 120 minutes transfusiongroup compared with 90 minutes group (p<0.001.Conclusion: Our results indicated that 90 minutes wassufficient for an effective exchange transfusion in severehyperbilirubinemic newborn infants. However longer exchangetransfusion durations may shorten the duration ofphototherapy.Key words: Indirect hyperbilirubinemia, exchange transfusion,newborns, outcome

    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.

    This study was aimed to establish the technique for preparation and storage of internal quality control pro-ducts by using existing blood sample resources of blood transfusion compatibility testing laboratory. 24 healthy blood donors with group A and RhD-positive were randomly selected, and 4 ml venous blood from these donors were collected, respectively. Based on the use of anticoagulant type, whether to add red blood cell preservation solution and the samples stored at room temperature for 1 or 2 hours daily, 24 specimens were randomly divided into 8 groups by using factorial design methodology. All samples in tube with cap were stored at 4 degrees C, and placed at room temperature for 1 or 2 hours daily. ABO, RhD blood group (recorded on the agglutination strength of the forward and reverse typing), IgM anti-B antibody titer, and free hemoglobin concentration in the supernatant for all samples were detected at 0, 7, 14, 21, 28, 35 days of products preservation. The results indicated that the red blood cell damage from the group used anticoagulants ACD-B and added the MAP red blood cell preservation solution and placed at room temperature 1 hour daily (recorded as A2B2C1 group) was kept minimal, and FHb concentration and FHb increments at each time point were the lowest (p 0.05). In conclusion, blood transfusion compatibility testing laboratory can use A2B2C1 program established by this study to prepare relatively stable modified whole blood internal quality control products in the existing conditions, which can be effectively preserved and meet the requirements of internal quality control for blood transfusion compatibility testing.

  9. Red cell exchange to mitigate a delayed hemolytic transfusion reaction in a patient transfused with incompatible red blood cells.

    2017-02-01

    A red cell exchange was performed to prevent a potentially fatal hemolytic transfusion reaction in a patient with anti-e who was transfused with e-antigen unscreened red blood cells during liver transplant surgery. A 64-year-old woman with cirrhosis due to hepatitis C was scheduled to receive a liver transplant. She had a previously documented anti-e, an antibody to the Rh(e)-antigen that is known to cause delayed hemolytic transfusion reactions. Pre-operatively and intra-operatively, she had massive hemorrhage which required transfusion of 34 e-antigen unscreened red blood cells (RBCs) most of which were incompatible. The hemoglobin dropped from 9.1 g/dL on post-operative day (POD)1 to 6.6 g/dL on POD6, with no evidence of blood loss. The bilirubin also increased from 5.0 mg/dL on POD 1 to 11.0 mg/dL on POD 6. As she was also becoming more hemodynamically unstable, a red cell exchange with 10 units of e-negative RBCs was performed on POD 6. She improved clinically and was extubated the following day. A few residual transfused e-positive red cells were detected after the red cell exchange until POD 13. This case illustrates how a red cell exchange can mitigate the potentially harmful effects of a delayed hemolytic transfusion reaction caused by red cell antibodies. With massive intraoperative blood loss it may not be possible to have antigen-negative RBCs immediately available, particularly for the e-antigen, which is present in 98% of the donor population. The ability to perform such a procedure may be life-saving in such patients. J. Clin. Apheresis 32:59-61, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    2013-10-01

    Full Text Available Background: Hemovigilance like quality systems and audits have become an integral part of Blood Transfusion Services in the developed countries and has contributed greatly to its development. Hemovigilance begins with donors and must enable the collection of information on reactions occurring during the donation of blood, selections of donors and to prevent such incidents. The aim of study was to help identify the trends of adverse events , occurring in blood donors at a tertiary-care hospital, to recommend best practices to improve donor care and safety Materials and Methods: This record-based study was conducted on all adverse events related to allogenic whole blood donations performed over 24 months. All whole blood donations were analyzed. All adverse events occurring during or at the end of the donation were noted using a standardized format and analyzed determining significance at p<0.05. Results: Overall rate was 0.3% with vasovagal reactions constituting 82%, and 18% mild syncopal reactions (p<0.001. Immediate vasovagal reaction with injury was very rare (0.007%. Vasovagal reactions showed a significant association with young age, female gender, first time donation status. Mean age of persons recording adverse effects was 30.23 ± 7.49 years as compared to those without adverse effects, 31.14 ± 8.56 years. Conclusion: Donor safety is an essential perquisite to increase voluntary blood donation. AE analysis helps in identifying the blood donors at risk of AE, applying appropriate motivational strategies, predonation counseling, care during and after donation, developing guidelines and hemovigilance programme in countries with limited resources.

    Full Text Available Background. Haemovigilance is a system consisting of the detection, collecting and analysis of information regarding unwanted and unexpected effects of blood transfusion that make it possible to take action in order to improve blood trasfusion safety. In a broader sense, it is defined as a set of surveillance procedures covering the whole transfusion chain from the collection of blood to the follow-up of recipients. In some European countries a haemovigilance system based on legislation was introduced during the last ten years, European Haemovigilance Network was organised and some results from the existing surveillance systems were reported. The paper presents haemovigilance activities in Slovenia.Conclusions. In Slovenia, many elements of haemovigilance are already included in the blood transfusion chain, but no unique system of data collection exists. We expect a new legislation on blood transfusion to help us with introducing a data collection system, analysis and activities in order to further improve blood transfusion safety.

    There is a huge need for blood transfusion in the newborn particularly due to the reduced marrow activity in the neonatal period. Despite widely use of blood products in the neonatal period, there is paucity of local data on the pattern, indications and reactions to blood transfusions in Nigerian newborns. This study evaluates the blood transfusion indications and patterns in special care baby unit and C1(2nd) of University College Hospital, Ibadan, Nigeria. A cross sectional study was carried on the recruited newborns and structured questionnaires were used to obtain bio data, medical problems, indications for blood transfusion, type of blood products transfused and clinical signs. Urinalysis was performed out before and after the transfusion. A total of 100 neonates were recruited into the study with a male: female ratio of (M: F= 1:1). The age range was 2-34 days and their weight ranged between 0.8kg to 3.6 kg with a mean weight of 1.64 kg. The main indications for transfusion were anaemia from prematurity & neonatal sepsis(NNS) 46%; (red cell replacement), NNS, Disseminated intravascular coagulation(DIC) & anaemia 24%; (partial exchange + top up + Fresh frozen plasma), neonatal jaundice(NNJ) & anaemia 14%; (whole blood), NNJ, NNS + anaemia 6%(Blood transfusion + Fresh frozen plasma), NNS + anaemia 10% (whole blood). Blood transfusion is still frequent in the study area and prematurity, neonatal sepsis and jaundice rank high in the indications. Transfusion reactions are rare in the evaluated neonates.

    It is now clearly established that the transfusion of blood from variant CJD (v-CJD) infected individuals can transmit the disease. Since the number of asymptomatic infected donors remains unresolved, inter-individual v-CJD transmission through blood and blood derived products is a major public health concern. Current risk assessments for transmission of v-CJD by blood and blood derived products by transfusion rely on infectious titers measured in rodent models of Transmissible Spongiform Encephalopathies (TSE) using intra-cerebral (IC) inoculation of blood components. To address the biological relevance of this approach, we compared the efficiency of TSE transmission by blood and blood components when administrated either through transfusion in sheep or by intra-cerebral inoculation (IC) in transgenic mice (tg338) over-expressing ovine PrP. Transfusion of 200 µL of blood from asymptomatic infected donor sheep transmitted prion disease with 100% efficiency thereby displaying greater virulence than the transfusion of 200 mL of normal blood spiked with brain homogenate material containing 103ID50 as measured by intracerebral inoculation of tg338 mice (ID50 IC in tg338). This was consistent with a whole blood titer greater than 103.6 ID50 IC in tg338 per mL. However, when the same blood samples were assayed by IC inoculation into tg338 the infectious titers were less than 32 ID per mL. Whereas the transfusion of crude plasma to sheep transmitted the disease with limited efficacy, White Blood Cells (WBC) displayed a similar ability to whole blood to infect recipients. Strikingly, fixation of WBC with paraformaldehyde did not affect the infectivity titer as measured in tg338 but dramatically impaired disease transmission by transfusion in sheep. These results demonstrate that TSE transmission by blood transfusion can be highly efficient and that this efficiency is more dependent on the viability of transfused cells than the level of infectivity measured by IC

    In Afghanistan, care of the acutely injured trauma patient commonly occurred in facilities with limited blood banking capabilities. Apheresis platelets were often not available. Component therapy consisted of 1:1 packed red blood cells and fresh frozen plasma. Fresh, whole blood transfusion often augmented therapy in the severely injured patient. This study analyzed the safety of fresh, whole blood use in a resource-limited setting. A retrospective analysis was performed on a prospectively collected data set of US battle injuries presenting to three US Marine Corps (USMC) expeditionary surgical care facilities in Helmand Province, Afghanistan, between January 2010 and July 2012. Included in the review were patients with Injury Severity Scores (ISSs) of 15 or higher receiving blood transfusions. Univariate analyses were performed, followed by multivariable logistic regression to describe the relationship between the treatment group and posttreatment complications such as trauma-induced coagulopathy, infection, mortality, venous thromboembolism, and transfusion reaction. Propensity scores were calculated and included in multivariable models to adjust for potential bias in treatment selection. A total of 61 patients were identified; all were male marines with a mean (SD) age of 23.5 (3.6) years. The group receiving fresh, whole blood was noted to have higher ISSs and lower blood pressure, pH, and base deficits on arrival. Traumatic coagulopathy was significantly less common in the group receiving fresh, whole blood (odds ratio, 0.01; 95% confidence interval, 0.00-0.18). Multivariable models found no other significant differences between the treatment groups. The early use of fresh, whole blood in a resource-limited setting seems to confer a benefit in reducing traumatic coagulopathy. This study's small sample size precludes further statement on the overall safety of fresh, whole blood use. Therapy study, level IV.

    Bleeding is a major cause of death in combat settings, and combat casualties in shock may benefit from fresh whole blood (FWB) transfusion. "Buddy transfusion" is a well-known lifesaving intervention, but little is known about donor combat safety aspects immediately after blood donation. The objectives of this study were to explore the effects of donation of 1 unit of blood on physical and combat-related performance among active duty soldiers. We also investigated the feasibility of a short training program to teach nonmedics buddy transfusion. Twenty-five fit male soldiers from a special forces unit were divided into three groups and tested on 1) a Bruce protocol treadmill stress test, push-ups, and pull-ups; 2) a 50-round rapid pistol shooting test; and 3) an uphill hiking exercise carrying a 20-kg backpack. After baseline testing, the soldiers performed the tests again (2-6 min) after donating 450 mL of blood. The training program included blood collection and reinfusion procedures and we measured success rate of venipuncture, time for blood collection, and success in placing sternal intraosseous needle and reinfusing 1 unit of autologous blood. We did not find any significant decrease in performance either in physical or in shooting performance after donating blood. Nonmedic soldiers had a 100% success rate in blood collection and also infusion on fellow soldiers after a short introduction to the procedures. This study supports the fact that buddy transfusion may be feasible for healthy well-trained soldiers and does not decrease donor combat performance under ideal circumstances. © 2012 American Association of Blood Banks.

    Full Text Available The Safety of the Blood Supply in any country is of utmost importance to safeguard patients from serious adverse events of blood transfusion. Implementation of a Quality System in the Blood Transfusion Service, with support of Government and Ministry of Health is a key element to guarantee safe blood. The IPA TAIB 2009 project - Strengthening of the Blood Safety System executed in 2013/14 provided the means to start implementing a Quality System in the Institute for Transfusion Medicine of the Republic of Macedonia. This project aimed to ultimately bring the Blood Transfusion Service to European Union standards, allowing the exchange of blood components and all other types of collaboration with other European Union countries in future. The project put the basis for unification of blood transfusion standards and operating procedures in the whole country as well as set up essential education of blood transfusion personnel.

    Donor selection based on blood group phenotypes, and blood processing such as leukocyte-depletion, gamma-irradiation or washing to remove plasma, are approaches for therapeutic or preventive use to manage the immunological complications of transfusion. Indications for specific components are prescribed in guidelines provided by (inter)national Transfusion Societies. Although the use of guidelines and protocols is in line with modern medicine, these can create a state of tension with the political sense of values to improve the viral safety of blood products and with the commercial exploitation of pooled plasma-products.A century of blood transfusion therapy has facilitated cancer treatment and advanced surgical interventions. The transfusion product has improved progressively, although mostly in response to disasters such as wars and AIDS. Every blood transfusion interacts with the immune system of the recipient. There are, however, very few quantitative figures to estimate the consequences. This review is based on the available literature on the clinical consequences of transfusion induced immunization and modulation. To a large degree the clinical consequences of transfusion induced immune effects are still a mystery.A blood transfusion is a medical intervention, which in many cases remains experimental with respect to the benefit/risk ratio. Ideally, this uncertainty should be communicated to patients and every transfusion included in a study. Such studies preferentially should be randomized because the perceived need for transfusion is associated with clinical conditions with a worse prognosis than those that do not receive transfusion. This difference may mask the interpretation of the transfusion effect. Since the blood supply services in almost all Western countries have been reorganized and nationalized, or at least operate to national quality standards, the measurement of risk: benefit of transfusion, whether political or evidence-based, needs to be

    2014-01-01

    Full Text Available Sepsis is a clinical syndrome characterised by systemic inflammation due to infection. There is a spectrum with severity ranging from sepsis to severe sepsis and septic shock. Even with optimal treatment, mortality due to severe sepsis or septic shock is significant and poses a challenge to management. Antibiotics, source control, resuscitation with fluids, vasopressor and inotropic agents are the main-stay of treatment for septic shock. These may be supplemented with transfusion of red blood cells and or blood products, in the case of anaemia to sustain sufficient oxygen delivery [1] or to manage associated haematological issues. Transfusion in sepsis has always been a debatable issue, especially in relation to choice of the fluid and the role of blood or blood product transfusion.

    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

    Blood transfusion is essential in current medical treatment. In the era of selling blood, around 50% of recipients seemed to be infected by hepatitis virus. After the establishment of the blood donation system and many safety measures, the risk of blood contamination has decreased markedly; however, blood products still have a risk of known and unknown pathogens. In this manuscript, we discuss the remaining problems of HBV and HIV-1. As emerging infectious diseases, we examine Trypanosoma crusi, West Nile virus, Chikungunya virus, and Dengue virus. Finally, XMRV is exemplified as a rumored virus. Gathering accurate information about pathogens and preparing for outbreaks in advance are crucial for blood safety.

    Full Text Available The acute blood transfusion reactions are responsible for causing most serious adverse events. Awareness about various clinical features of acute and delayed transfusion reactions with an ability to assess the serious reactions on time can lead to a better prognosis. Evidence-based medicine has changed today′ s scenario of clinical practice to decrease adverse transfusion reactions. New evidence-based algorithms of transfusion and improved haemovigilance lead to avoidance of unnecessary transfusions perioperatively. The recognition of adverse events under anaesthesia is always challenging. The unnecessary blood transfusions can be avoided with better blood conservation techniques during surgery and with anaesthesia techniques that reduce blood loss. Better and newer blood screening methods have decreased the infectious complications to almost negligible levels. With universal leukoreduction of red blood cells (RBCs, selection of potential donors such as use of male donors only plasma and restriction of RBC storage, most of the non-infectious complications can be avoided.

    Full Text Available Background: Blood transfusion as a part health services should be provided under appropriate indications and in a safe manner. In Indonesia, blood collection is run by the Blood Transfusion Unit of Indonesian Red Cross, where the blood is screened, processed into blood components, and finally distributed to hospitals. The purpose of this study was to describe the profile of blood transfusion requests from hospitals that do not have blood bank facility to the Bandung Blood Transfusion Unit, Indonesian Red Cross. Methods: A descriptive study was carried out using secondary data from Bandung Blood Transfusion Unit Indonesian Red Cross (UTD PMI Bandung. All blood request forms from hospitals during 2011 were collected and analyzed. Variables in this study were the amount of blood units, blood components, blood type, and indications of blood transfusion. Results: The number of blood units requested by hospitals were 35,841 units. The most blood units requested was in August 2011. The blood component requested was the packed red cell (61.1%, whole blood (17.4%, thrombocyte concentrate (10.6%, and fresh frozen plasma (7%. The total percentage of O, A, B and AB blood types were 36.1%, 28.6%, 27.5%, and 7.9% respectively. The most frequent indication for transfusion was anemia (61.7%, followed by surgery and other causes of bleeding. Conclusions: The total blood units requested by hospitals vary each month. The most blood component requested is Packed Red Cell and the type of blood is O blood type. The most frequent indication is anemia.

    Acute cyclosporine A (CsA) intoxication after organ transplantation may occur during the changeover from one form of drug to another, or from miscalculation of dosage. Sometimes, it may cause severe hepatotoxicity, nephrotoxicity and neurotoxicity. However, the therapeutic plasma exchange for the CsA intoxication was not established. Here, we present a case of very severe CsA intoxication after cardiac transplantation who recovered from intoxication without long-term sequelae via whole blood exchange; therapeutic erythrocytapheresis followed by total plasma exchange.

    Full Text Available Albert Farrugia,1,2 Eleftherios Vamvakas31College of Medicine, Biology and Environment, Australian National University, Acton, ACT, Australia; 2Centre for Orthopaedic Research, Department of Surgery, Faculty of Medicine and Surgery, University of Western Australia, Perth, WA, Australia; 3Cedars-Sinai Medical Center, Los Angeles, CA, USAAbstract: 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.Keywords: indications, emerging countries, patient blood management

    To get full knowledge of current conditions and development in the past seven years of clinical transfusion practice in Sichuan, China. This survey was performed by means of a questionnaire which consisted of three parts of questions including basic conditions of blood banks in the hospitals, procedures for clinical blood transfusion and the utilization of different types of blood products. Thirty-five representative hospitals from different geographic locations in Sichuan province participated in this survey. All of the 35 hospitals returned the questionnaires and 33 hospitals (94.3%) answered the questions completely. The blood bank information system began to be used by more hospitals from 2006 (21.21%, 7/33) to 2012 (48.48%, 16/33). Automated grouping and cross-matching systems have not been used in level 2 hospitals and only 3 level 3 hospitals used automated systems in 2012. Still less common were procedures for evaluation of blood order forms for appropriateness (2/33, 6.06%) and evaluation of appropriateness and effect of blood component transfusion (8/33, 24.2%), and all the hospitals having these procedures are level 3 hospitals. The percentage of whole blood usage in the volume of all types of blood products used decreased a lot from 7.45% in 2006 to 0.16% in 2010. Technological instruments for bedside checking are not used by any of the hospitals. The transfusion service degree of the hospitals in Sichuan, China, has developed a lot in the past seven years; however, there are still some problems including whole blood still being used, albeit decreasing; lack of independent blood banks within the hospitals; lack of dedicated personnel for the transfusion services; lack of education; lack of blood bank information systems and automation; lack of screening for appropriateness for blood orders.

However, cancer occurrence in transfusion recipients remains poorly characterized. We used computerized files from Scandinavian blood banks to identify a cohort of 888,843 cancer-free recipients transfused after 1968. The recipients were followed from first registered transfusion until the date of death, emigration, cancer diagnosis, or December 31, 2002, whichever came first. Relative risks were expressed as ratios of the observed to the expected numbers of cancers, that is, standardized incidence ratios (SIRs), using incidence rates for the general Danish and Swedish populations as a reference. All statistical tests were two-sided. During 5,652,918 person-years of follow-up, 80,990 cancers occurred in the transfusion recipients, corresponding to a SIR of 1.45 (95% confidence interval [CI] = 1.44 to 1.46). The SIR for cancer overall decreased from 5.36 (95% CI = 5.29 to 5.43) during the first 6 months after transfusion to 1.10 or less for follow-up periods more than 2 years after the transfusion. However, the standardized incidence ratios for cancers of the tongue, mouth, pharynx, esophagus, liver, and respiratory and urinary tracts and for squamous cell skin carcinoma remained elevated beyond 10 years after the transfusion. The marked increase in cancer risk shortly after a blood transfusion may reflect the presence of undiagnosed occult cancers with symptoms that necessitated the blood transfusion. The continued increased risk of tobacco- and alcohol-related cancers suggests that lifestyle and other risk factors related to conditions prompting transfusion rather than transfusion-related exposures per se are important to the observed cancer occurrence in the recipients.

    Science.gov (United States)

    Andreu, Georges

    2015-02-01

    Each year, more than three millions of blood components are transfused to more than five hundred thousand patients in France. The optimal use of blood components requires that physicians prescribing blood components master the clinical indications of red blood cells concentrates, platelet concentrates and fresh frozen plasma. In addition, physicians in charge of blood component prescription should provide adequate pre- and post-transfusion information to their patients. Compliance of blood components administration in patients with safety guidelines contributes as well to their optimal use. In addition, for each blood component transfused, a proper evaluation of its safety and its efficacy should be done. Finally, a regular evaluation of transfusion practice in hospital services were blood components are used, through audits made in cooperation with their blood component provider, either blood transfusion centre or the hospital blood bank, enables to appreciate the level of compliance with safety and clinical guidelines, and more globally how the transfusion process is mastered.

    Massive transfusion practices were transformed during the 1970s without solid evidence supporting the use of component therapy. A manual literature search was performed for all references to the lethal triad, acute or early coagulopathy of trauma, fresh whole blood, and component transfusion therapy in massive trauma, and damage control resuscitation. Data from recent wars suggest traditional component therapy causes a nonhemostatic resuscitation worsening the propagation of the lethal triad hastening death. These same studies also indicate the advantage of fresh whole blood over component therapy even when administered in a 1:1:1 replacement ratio. Published by Elsevier Inc.

    disease. Perioperative blood management strategies include minimizing blood draws, restricting transfusions, intraoperative cell salvage, acute normovolemic hemodilution, antifibrinolytic agents, and using point-of-care tests to guide transfusion decisions. However, further research is needed for the use of intravenous iron, erythropoiesis-stimulating agents, and possible use of whole blood and pathogen inactivation. There are numerous areas where newly formed collaborations could be used to investigate pediatric transfusion, and these studies would provide critical data to support vital pediatric PBM programs to optimize neonatal and pediatric care.

    BACKGROUND: Treating anaemia with red blood cell (RBC) transfusion is frequent, but controversial, in patients with septic shock. Therefore we assessed characteristics and outcome associated with RBC transfusion in this group of high risk patients. METHODS: We did a prospective cohort study at 7...... general intensive care units (ICUs) including all adult patients with septic shock in a 5-month period. RESULTS: Ninety-five of the 213 included patients (45%) received median 3 (interquartile range 2-5) RBC units during shock. The median pre-transfusion haemoglobin level was 8.1 (7.4-8.9) g...... and SAPS II and SOFA-score on day 1. CONCLUSIONS: The decision to transfuse patients with septic shock was likely affected by disease severity and bleeding, but haemoglobin level was the only measure that consistently differed between transfused and non-transfused patients....

    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.

    Surgery in patients with sickle cell disease is associated with high morbidity. To reduce this high morbidity, different preoperative transfusion regimens were introduced. However, blood transfusion is associated with problems. This prospective study aims to establish the safety of conducting laparoscopic cholecystectomy without transfusion in sickle cell disease patients. Forty patients (16 males and 24 females; mean age 26.6 years) undergoing laparoscopic cholecystectomy for cholelithiasis were divided into 2 matched groups: Group I "no transfusion" (n=24 patients; 60%) and Group II "transfusion" (n=16; 40%). In Group II, 9 patients (22.5%) received a simple transfusion and 7 (17.5%) a partial exchange transfusion. Group II patients had significantly higher levels of Hb-S prior to transfusion. They developed a significantly higher complication rate (25% vs. 0%) and subsequently longer hospital stay (3.9±2 vs. 2.1±1.4). Moreover, there was no significant difference in the complications between the simple transfusion and partial exchange transfusion subgroups. Surgery in SCD patients is safe without a preoperative blood transfusion. Moreover, preoperative blood transfusion is associated with significantly higher postoperative complications and longer hospital stay. Hence, a "no transfusion" policy is recommended.

    2012-12-01

    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.

    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

    In the 20th century, blood transfusion has become an indispensable therapy in carrying out and improving many medical and surgical applications. Its scope of influence goes well beyond that of medicine, because blood donation, an action with high social significance, is completely connected to progress in the field. The purpose of this research was to study, through films that show transfusion or blood donation, the impression that has been given to the public in the course of the 20th century and its sociologic impact. To accomplish this, we have used various sources from Histories of Cinema and from the Internet to identify films from different countries and from different epochs that touch on this theme. With these two components, the act of donation and the act of transfusion, the relatively short history of blood transfusion is distinguished by upheavals in both the medical and the sociopolitical fields of the past century. Movies, the most commonly shared cultural event and mirror of society, have simultaneously gone through their first century by showing the diversity of our feelings and the human condition. Through various cinematographic references, the authors offer an analysis of the use, by the Seventh Art, of values and illustrations that use blood donation and transfusion.

    2013-07-01

    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.

    Public concerns regarding the safety of transfused blood have prompted re-consideration of the use of allogeneic (from an unrelated donor) red blood cell (RBC) transfusion, and a range of techniques designed to minimise transfusion requirements. To examine the evidence for the efficacy of desmopressin (1-deamino-8-D-arginine-vasopressin), in reducing perioperative blood loss and the need for red cell transfusion in patients who do not have congenital bleeding disorders. Articles were identified by: computer searches of OVID MEDLINE, EMBASE, and Current Contents (to August 2000) and web sites of international health technology assessment agencies (to May 1998). References in the identified trials and review articles were checked and authors contacted to identify additional studies. Randomised controlled parallel group trials in which adult patients, scheduled for non-urgent surgery, were randomised to DDAVP, or to a control group, who did not receive the intervention. Trial quality was assessed using criteria proposed by Schulz et al. (1995) and Jadad et al. (1996). The principal outcomes were: the number of patients exposed to red cells, and the amount of blood transfused. Other clinical outcomes are detailed in the review. Fourteen trials of DDAVP (N=1034) reported data on the proportion of patients exposed to allogeneic RBC transfusion. In subjects treated with DDAVP the relative risk of exposure to peri-operative allogeneic blood transfusion was 0.98 (95%CI: 0.88 to 1.10) compared with control. In DDAVP-treated patients the relative risk of requiring re-operation due to bleeding was 0.56 (95%CI: 0.18 to 1.73). There was no statistically significant effect overall for mortality and non-fatal myocardial infarction in DDAVP-treated patients compared with control (RR=1.53: 95%CI: 0.58 to 4.05) and (RR=1.52: 95%CI: 0.67 to 3.49) respectively. There is no convincing evidence that desmopressin minimises perioperative allogeneic RBC transfusion in patients who do not

    Blood is donated either as whole blood, with subsequent component processing, or through the use of apheresis devices that extract one or more components and return the rest of the donation to the donor. Blood component therapy supplanted whole blood transfusion in industrialized countries in the middle of the twentieth century and remains the standard of care for the majority of patients receiving a transfusion. Traditionally, blood has been processed into three main blood products: red blood cell concentrates; platelet concentrates; and transfusable plasma. Ensuring that these products are of high quality and that they deliver their intended benefits to patients throughout their shelf-life is a complex task. Further complexity has been added with the development of products stored under nonstandard conditions or subjected to additional manufacturing steps (e.g., cryopreserved platelets, irradiated red cells, and lyophilized plasma). Here we review established and emerging methodologies for assessing blood product quality and address controversies and uncertainties in this thriving and active field of investigation.

    Transfusion is a mixed discipline which includes the production of blood components, applied biology aiming in particular at establishing the highest compatibility for immunological characteristics between blood components to be delivered to patients and recipients, and, finally translational medicine to evaluate the effectiveness of the transfused products and to proactively avoid hazards, at least those that are preventible and can be anticipated. The whole chain takes place with the concern of continuous improvement of quality and safety. These two principles (quality/safety) have been and still are concerns of constant progress applicable to all the transfusion chain steps; they benefit from programs of Research and Development (R&D). Fundamental research, basic but also applied and clinical research, accompanies, in a constantly joint manner, scientific and medical progresses by providing new solutions to dampen the current problems and to prepare the future.

    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.

    2016-01-01

    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

    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.

    Currently transfused cellular components of blood are not available in a sterile form and carry a small risk of transmitting viral and parasite diseases. Using phthalocyanines and red light, lipid enveloped viruses, e.g., HIV-1, can be inactivated in red blood cell concentrates (RBCC). Under conditions leading to virus sterilization the blood borne parasites Trypanosoma cruzi (Chagas disease) and Plasmodium falciparum (malaria) could be eliminated to undetectable levels (> 4 log10 kill). RBC damage during treatment could be avoided by increasing the light fluence rate to 80 mW/cm2, and by including the free radical scavenger glutathione and the vitamin E derivative Trolox during light exposure. Similar sterilization of platelet concentrates was achieved with the psoralen derivative AMT and UVA light. Platelet damage due to PUVA treatment was avoided by including the plant flavonoid rutin during irradiation. It is concluded that elimination of the risk of transmitting pathogens during blood transfusion is feasible with photochemical treatments.

    In Sickle Cell Anemia (SCA) patient blood transfusions are an important part of treatment for stroke and its prevention. However, blood transfusions can also lead to complications such as Reversible Posterior Leukoencephalopathy Syndrome (RPLS). This brief report highlights two cases of SCA who developed such neurological complications after a blood transfusion. RLPS should be considered as the cause of neurologic finding in patients with SCA and hypertension following a blood transfusion. PMID:28127478

    An effective hospital transfusion culture should encourage clinicians to consider the possibility of transfusion in their patients well before the need actually arises, and to plan ahead in an attempt to use blood products most efficiently. Strategies for improved blood utilization include timely and adequate preoperative assessment of risk, optimization of baseline hemoglobin, anticipation of potential transfusion problems, intraoperative techniques to minimize blood loss, blood conservation technologies, transfusion guidelines and targeted therapy, point of care testing, and massive transfusion protocols. Attention to these elements promotes a safe and cost-effective transfusion culture. Copyright © 2012 Elsevier Inc. All rights reserved.

    1983-11-01

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

    2015-02-01

    Over the years, transfusion medicine has been faced to many different problems, notably those related to transmission of pathogens. Major progresses have been accomplished in terms of security. However, nowadays, the discipline is confronted to the day-to-day variability and availability of blood products. More and more donors are excluded from blood donation due to various reasons, and the donor selection criteria have increased over the years, influencing the number of donors able to give blood. This paradox represents one of the constraints that transfusion medicine should resolve in the future. This paper presents some aspects either common or different between France and Switzerland.

    It is often an accepted practice that a 20-gauge-or-larger catheter is used for the safe transfusion of blood in adult patients, but it is unclear what evidence supports this practice. This article tells the story of how a small team of oncology nurses designed and implemented an evidence-based practice project to challenge that convention. A literature search and a consultation with the standards of the American Association of Blood Banks and the Infusion Nurses Society determined that a smaller-than-20-gauge catheter can be used safely to transfuse blood in adults, a discovery that led to a change in policy and practice at the authors' institution.

    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.

    2017-10-01

    The aim of this study was to determine the rate of blood component wastage before and after interventions at Yazd Blood Transfusion Center. The growing need for blood components along with blood safety issues and rising costs constantly pressurise blood centres to improve their efficiency. Reducing the quantity of discarded blood at all stages of the supply chain can decrease the total costs. Data on discarded blood components were extracted from the database of Yazd Blood Transfusion Center. Multiple interventions, including implementation of wastage management standard operating procedures and reduction of red blood cells (RBCs) inventory level, were implemented. Discard rates of blood components in the 3 years after intervention (2013-2015) were compared with the discard rates in the 3 years before interventions. The total wastage rate of blood components decreased by almost 60%. Discard rates of RBCs, platelets and plasma decreased from 9·7%, 18·5% and 5·4% to 2·9%, 10·5% and 2·3%, (P < 0·001) after intervention, respectively. The most prevalent reason for discarding units was expiration of RBCs and platelets. Plasma units were discarded mostly due to technical faults during processing. The cost saving of reduction in blood wastage was estimated to be 1,500,000 dollars. Interventions had a significant impact on the reduction of blood wastage with respect to both cost and blood supply saving. © 2017 British Blood Transfusion Society.

    2012-07-01

    Paul Schmidt was born in 1925 into the Greatest Generation. Events during military service decided him on the study of medicine. Early research training in red cell preservation that continued during his medical studies opened a 20-year career at the National Institutes of Health (NIH). Beginning in 1954 at the Blood Bank of the NIH Clinical Center, he had exposure to the pioneers who had translated transfusion's wartime beginnings into civilian applications. Work inside the unique NIH clinical research atmosphere together with many of his students provided a fertile field for the growth of what has become transfusion medicine. Topics described range from early studies on platelets and on hepatitis to the background in Washington health politics leading to the National Blood Policy. National and global organizational activity and a second career in community blood service added to his 65 years of experience. The story as transfusion history is presented as a template for future progress. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Babesiosis is a tick born zoonosis caused by red blood cell parasites of the genus Babesia. It is caused predominantly by B. microti and B. divergens, microti being more common in the US. The parasites are transmitted by Ixodes tick to their host but infection can also spread by blood transfusion and perinatally. Clinical manifestations vary from subclinical infection to fulminating disease depending upon the immune status of the patient. About half of patients, hospitalized with babesiosis, develop complication with fatality rates of 6 to 9% which increase up to 21% among those with immunosuppression. A case of 58-year-old previously healthy man, infected by B. microti, was reported on 2000 who presented with severe disease characterized by severe anemia, DIC, and renal and respiratory failure. First case of overwhelming septic shock without respiratory involvement due to babesiosis in a healthy patient with an intact spleen was published in a case report on 2011. Since our patient here is an immunocompetent healthy male with intact spleen presenting with severe babesiosis requiring exchange transfusion, this presentation of Babesia is rare and warrants further study.

    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 blood transfusion while undergoing primary posterior lumbar fusion, and risk factors for these occurrences were characterized.

    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

    2014-10-01

    Full Text Available The aim of the study was to determine the suitability of basic haematological, biochemical, and gasometric tests in checking the effectiveness of transfusion therapy in foals during isoerythrolysis. The number of red blood cells, haemoglobin, haematocrit, and partial pressure of carbon dioxide, oxygen, and blood pH was determined immediately before and several times after blood transfusion. The concentration of serum free bilirubin was also measured to confirm haemolysis. Fluids (0.9% NaCl, multielectrolytic fluid, 5% glucose and antibiotics (penicillin, amikacin were provided to the foals. The lowest values of haematological parameters were observed before transfusion. This was accompanied by decreased partial pressure of oxygen, low pH, and increased arterial carbon dioxide tension. Transfusion of whole blood led to a gradual normalisation of the haematological parameters, also accompanied by the normalisation of gasometric indicators (decrease in pCO2 and pO2 and pH increase. Monitoring of selected haematological and gasometric parameters allows to evaluate the efficacy of blood transfusion during treatment of haemolytic disease of foals.

    Autologous blood transfusion (ABT) is rarely employed in patients with end-stage renal disease (ESRD); these patients are usually anemic. Since 1998, we have attempted ABT for ESRD patients undergoing living-related kidney transplantation. Among 20 patients enrolled in this study the preoperative hemoglobin and hematocrit levels were 10.0 +/- 1.2 mg/dL (range, 8.1-11.7) and 30.0 +/- 3.7% (range, 24.7-34.3), respectively. Blood volume collected on each occasion was 235.7 +/- 57.7 mL (range, 200-400), and the number of blood collections was 2.45 +/- 0.9 (range, 1-4). Total collected volume was 567.5 +/- 157.5 mL (range, 400-800). Symptomatic hypotension was seen in two patients, but vital signs recovered spontaneously. No other problems related to blood collection were observed. Allogeneic transfusion was need in only one patient (5%). ABT was safe and efficacious in ESRD patients scheduled for living-related kidney transplantation.

  7. PREVENTIVE MEASURES FOR THE IMPROVEMENT OF THE SAFETY OF BLOOD TRANSFUSION AND VIRTUAL TRANSFUSION LABORATORY

    2002-04-01

    Full Text Available Background. Even though blood transfusion is a relatively safe form of therapy, because of the eventual administrative errors in the transfusion chain between the blood donor and the recipient of blood, transfusion errors still occur. Therefore, it is imperative to ensure an utmost extent of safety and reliability of all transfusion related procedures. The safety of blood transfusion can be improved by preventive actions, i.e. implementation of the total quality management concept, haemovigilance and virtual transfusion laboratory. In the resulting system, the information web, robotics, computer sciences and communication technologies ensure safe and reliable identification of the patients, blood donors, corresponding test samples and blood products. Apart form this; the modern technologies enable the automation of laboratory testing, the integrity of laboratory results and enable an optimal use of blood.Conclusions. For an improved transfusion safety in Slovenia, adoption of corresponding prevention as well as haemovigilance is necessary. Identification errors can be prevented by implementation of the wristbands systems with the code bars for the tagging of the patient and his biological samples, whereas the administrative errors in the blood bank and transfusion laboratory can be prevented by implementation of information systems and automation.We assume that the virtual transfusion laboratory will become an integral part of the new Slovenian transfusion web and will speed up, unify and simplify today’s methods of ordering and administering blood products. To the attending physician, it will enable the choice of optimal transfusion therapy schedule and at the same time, it will enable the supervision of individual orders, deviations and indications, all of which is needed in order to analyse and improve the quality and the costs of the treatment. These services represent the first obligatory step for the modernisation of the transfusion

    Increasing blood supply safety is one of the most important goals of blood services in the world. In this study, we reviewed the prevalence rate and the trends of three main infections in whole blood donations and strategies for improving blood safety in Yazd blood transfusion center, Iran. In this cross sectional study, data on hepatitis B, C and HIV infection were extracted from Iranian Donor Database of blood donation from 2004 to 2010 in Yazd province. All donors with positive confirmatory test were included. The data was analyzed by SPSS software due to demographic factors. The prevalence rate of hepatitis B, C and HIV infection decreased during these years (From 0.37%, 0.14% and 0 percent in 2004 to 0.14%, 0.05% and 0 in 2010, respectively). Both hepatitis B and C infections were significantly more in first-time blood donors with BSc or BA educational level. The prevalence rate of hepatitis B was significantly higher in donors with less than 20 year-old and female donors. The prevalence rate of hepatitis C was higherin30-39 age group (P-value= 0.014). The results showed that the strategies used for improving blood safety were efficient. Increasing public knowledge on blood-borne infections and their routes of transmission, importance of donating blood only by healthy donors are necessary to have a safe blood supply in future.

    Directory of Open Access Journals (Sweden)

    Hyoung Soo Kim

    2017-02-01

    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.

    Blood is a vital resource commonly used in burn patients; however, description of blood transfusions in severe burns is limited. The purpose of this study was to describe the epidemiology of blood transfusions and determine factors associated with increased transfusion quantity. This is a retrospective study of total 133 patients with >40% total body surface area (TBSA) burns admitted to the burn center of Changhai hospital from January 2008 to December 2013. The study characterized blood transfusions in severe burn patients. Univariate and Multivariate regression analyses were used to evaluate the association of clinical variables with blood transfusions. The overall transfusion rate was 97.7% (130 of 133). The median amount of total blood (RBC and plasma), RBC and plasma transfusions was 54 units (Interquartile range (IQR), 20-84), 19 units (IQR, 4-37.8) and 28.5 units (IQR, 14.8-51.8), respectively. The number of RBC transfusion in and outside operation room was 7 (0, 14) and 11 (2, 20) units, and the number of plasma was 6 (0.5, 12) and 21 (11.5, 39.3) units. A median of one unit of blood was transfused per TBSA and an average of 4 units per operation was given in the series. The consumption of plasma is higher than that of RBC. On multivariate regression analysis, age, full-thickness TBSA and number of operations were significant independent predictors associated with the number of RBC transfusion, and coagulopathy and ICU length showed a trend toward RBC consumption. Predictors for increased plasma transfusion were female, high full-thickness TBSA burn and more operations. Severe burn patients received an ample volume of blood transfusions. Fully understanding of predictors of blood transfusions will allow physicians to better optimize burn patients during hospitalization in an effort to use blood appropriately.

    Toward the end of World War I and during World War II, whole-blood transfusions were the primary agent in the treatment of military traumatic hemorrhage. However, after World War II, the fractionation of whole blood into its components became widely accepted and replaced whole-blood transfusion to better accommodate specific blood deficiencies, logistics, and financial reasons. This transition occurred with very few clinical trials to determine which patient populations or scenarios would or would not benefit from the change. A smaller population of patients with trauma hemorrhage will require massive transfusion (>10 U packed red blood cells in 24 h) occurring in 3% to 5% of civilian and 10% of military traumas. Advocates for hemostatic resuscitation have turned toward a ratio-balanced component therapy using packed red blood cells-fresh frozen plasma-platelet concentration in a 1:1:1 ratio due to whole-blood limited availability. However, this "reconstituted" whole blood is associated with a significantly anemic, thrombocytopenic, and coagulopathic product compared with whole blood. In addition, several recent military studies suggest a survival advantage of early use of whole blood, but the safety concerns have limited is widespread civilian use. Based on extensive military experience as well as recent published literature, low-titer leukocyte reduced cold-store type O whole blood carries low adverse risks and maintains its hemostatic properties for up to 21 days. A prospective randomized trial comparing whole blood versus ratio balanced component therapy is proposed with rationale provided.

    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.

    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.

    The acute medical services could not exist without blood transfusions--life-savers in many situations. But transfusions can also be a quick and easy route for the transmission of infectious agents such as HIV, HBV, HCV and malaria. Infection through blood supply is a major issue in all countries but particularly in those with economic constraints which limit safety. This study was carried out in India (March-May 1997) and involved centres in Delhi, Calcutta and Vellore. It examined many aspects of blood transfusion including donor screening, use of professional donors, blood testing and criteria for blood use. The many problems in Indian blood transfusion services are mirrored in other countries. Here we examine the problems, priorities and practicalities of blood transfusion particularly in developing countries.

    Summary One focus of improvement of burn care in Ukraine was the management of blood loss and blood transfusions in burn patients. The aim of this project was to analyze blood transfusion triggers in burn patients and outcomes at eleven major burn centers in Ukraine. This multicenter retrospective study reviewed four years of data on blood-transfused burn patients admitted to eleven major burn centers in Ukraine. Data analyzed included: demographics, characteristics of the burns, complications of burn injury, triggers for blood transfusions and outcomes. A total of 928 burn patients who received 2,693 blood transfusions from 11 major burn centers over a four-year period, were studied. Regardless of the total body surface area (TBSA) that was burned, blood transfusions were administered with a hemoglobin (Hb) trigger value of around 9 g/dL. Roughly one third (30.5%) of all transfusions were given in patients with a TBSA ≤ 10%. We demonstrated that Ukrainian doctors were using the same Hb trigger for blood transfusions for all Ukrainian burn patients, which suggested a need to change blood transfusion policy. PMID:27279803

    2017-06-01

    Although the administration of blood and blood products can be lifesaving, transfusions in exotic species are less common because of the lack of knowledge of a species' blood groups, the availability of species-specific donors, and possible adverse effects. Recently, blood groups were elucidated in great apes; however, few reports have been published regarding actual transfusion situations in these species. This information is critical because poorly executed transfusions can compromise already weakened patients or result in the death of the recipient. In 2014, a retrospective survey of U.S. zoos housing great apes received 45 of 67 responses; from which, 12 transfusion cases in great apes were identified, including Sumatran orangutans ( Pongo pygmaeus sumatraensis, n = 4), chimpanzee ( Pan troglodytes , n = 1), and western lowland gorillas ( Gorilla gorilla gorilla, n = 7). These animals, ranging from birth to 31 yr, received intravenous transfusions of whole blood, packed red blood cells, or human albumin. Overall, animals that received transfusions for anemia because of chronic illness or blood loss survived, but those individuals with concurrent life-threatening issues did not survive. No adverse reactions related to the transfusion occurred, except in two orangutans given human albumin.

    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.

    Full Text Available Anemia is common in critically ill patients. As a consequence packed red blood cell (PRBC transfusions are frequent in the critically ill. Over the past two decades a growing body of literature has emerged, linking PRBC transfusion to infections, immunosuppression, organ dysfunction, and a higher mortality rate. However, despite growing evidence that risk of PRBC transfusion outweighs its benefit, significant numbers of critically ill patients still receive PRBC transfusion during their intensive care unit (ICU stay. In this paper, we summarize the current literature concerning the impact of anemia on outcomes in critically ill patients and the potential complications of PRBC transfusions.

    The aim of blood transfusion risk management is to improve the quality of blood products and to assure patient safety. We utilize failure mode and effect analysis (FMEA), a tool employed for evaluating risks and identifying preventive measures to reduce the risks in blood transfusion. The failure modes and effects occurring throughout the whole process of blood transfusion were studied. Each failure mode was evaluated using three scores: severity of effect (S), likelihood of occurrence (O), and probability of detection (D). Risk priority numbers (RPNs) were calculated by multiplying the S, O, and D scores. The plan-do-check-act cycle was also used for continuous improvement. Analysis has showed that failure modes with the highest RPNs, and therefore the greatest risk, were insufficient preoperative assessment of the blood product requirement (RPN, 245), preparation time before infusion of more than 30 minutes (RPN, 240), blood transfusion reaction occurring during the transfusion process (RPN, 224), blood plasma abuse (RPN, 180), and insufficient and/or incorrect clinical information on request form (RPN, 126). After implementation of preventative measures and reassessment, a reduction in RPN was detected with each risk. The failure mode with the second highest RPN, namely, preparation time before infusion of more than 30 minutes, was shown in detail to prove the efficiency of this tool. FMEA evaluation model is a useful tool in proactively analyzing and reducing the risks associated with the blood transfusion procedure. © 2013 American Association of Blood Banks.

    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.

    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

    Afghanistan is a country with population of over 28 million. The long term conflicts have devastated country's qualified resources including human resources. ANBSTS was established by MoPH as the country national blood service. Currently in addition to central and regional blood centers of ANBSTS many other hospitals have their own transfusion services. Blood donation in Afghanistan mainly depends on replacement donors. Donor selection and donor interview are not very efficient. Most of the blood in Afghanistan is administered as fresh whole blood. Although blood transfusion services in Afghanistan require more efforts to be fully efficient, based on recent improvements in working procedures of ANBSTS a promising future for blood transfusion services in Afghanistan is predicted.

    It is not uncommon in transfusion practice to see blood/components with abnormal colored plasma. The present study was conducted to identify and determine the etiology of blood and/or blood components showing altered color. The present study was conducted in the Department of Transfusion Medicine, Government Medical College and Hospital, Chandigarh over a period of seven months. All the blood units/components having an abnormal appearance were segregated as: 1. Green discoloration. 2. Yellow discoloration. 3. Bright cherry red color. 4. Lipemic plasma. The donor's history was carefully evaluated and relevant investigations were done depending on discoloration. Seventeen units out of 7370 (0.23%) donations showed discoloration. In 3 units the plasma was green, 5 units were yellow, in 3 units PRBC/WB unit was bright cherry red and in the remaining 6 units the plasma was lipemic. Total bilirubin of all the 5 donors with yellowish plasma ranged from 1.6 to 2.3mg/dl. The hemoglobin and hematocrit of two out of three donors with cherry red discoloration of PRBC/WB was low. All the donors with lipemic plasma gave history of intake of fatty meal prior to donating blood. The existing rules prohibit issue of blood and blood components if the plasma is abnormal in color. Our study showed that many of the discolored units could have been safely transfused but further larger studies are required to confirm the safety of recipients receiving such units.

    2016-04-01

    Transfusion support is a key enabler to the response to mass casualty events (MCEs). Transfusion demand and capability planning should be an integrated part of the medical planning process for emergency system preparedness. Historical reviews have recently supported demand planning for MCEs and mass gatherings; however, computer modeling offers greater insights for resource management. The challenge remains balancing demand and supply especially the demand for universal components such as group O red blood cells. The current prehospital and hospital capability has benefited from investment in the management of massive hemorrhage. The management of massive hemorrhage should address both hemorrhage control and hemostatic support. Labile blood components cannot be stockpiled and a large surge in demand is a challenge for transfusion providers. The use of blood components may need to be triaged and demand managed. Two contrasting models of transfusion planning for MCEs are described. Both illustrate an integrated approach to preparedness where blood transfusion services work closely with health care providers and the donor community. Preparedness includes appropriate stock management and resupply from other centers. However, the introduction of alternative transfusion products, transfusion triage, and the greater use of an emergency donor panel to provide whole blood may permit greater resilience. © 2016 AABB.

    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 aim of this study was to evaluate the introduction of two-sample policy for transfusion at our hospital and reduction of the risk of ABO incompatible transfusion. ABO incompatible transfusion can be a fatal but avoidable event. Wrong blood in tube is a cause of ABO incompatible transfusion and there are various strategies available to try and expunge this event. Survey of policy/practice before and after the introduction of a two-sample policy. Staff training is inadequate in reducing the risk of ABO incompatible transfusion. A two-sample policy was introduced and does not significantly increase workload or use of group O blood and does not compromise patient safety by causing delay in blood provision. Post hoc analysis confirms good understanding of the policy by medical staff. Observation of medical staff taking transfusion samples demonstrated consistent deviation from policy, enforcing the need for confirmatory samples. A two-sample policy adds an extra layer of safety to transfusion practice and can be introduced without creating new problems. © 2014 The Authors.

    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.

    2017-01-01

    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.

    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.

    Reduced use of allogenic blood components is a key issue in cardiac surgery. Several methods to conserve blood have been used; reinfusion of shed mediastinal blood (RSMB) has found widespread acceptance, but the efficacy and safety are still debated. The purpose of this study was to evaluate the effects of RSMB on the use of allogenic blood components and selected complications. Six hundred and twenty-three consecutive cardiac surgery patients in three successive periods, of whom patients in the middle period did not receive RSMB due to manufacturer delivery problems, were evaluated. Patients and procedures were characterized by EuroSCORE. Prospective collected data were: units of transfused allogenic blood, fresh frozen plasma (FFP) and platelets, postoperative blood loss and postoperative complications such as dialysis, re-operation due to bleeding, sternal infection and stroke. Length of stay in ICU was used as a general indicator of perioperative complications. The number of patients receiving allogenic blood in periods with RSMB was significantly lower (36.5% versus 54.9%, ptransfused blood units was lower in patients receiving RSMB (2.07 versus 3.41, p=0.029), while FFP (1.34 versus 2.01, p=0.11) and platelets (0.58 versus 0.95, p=0.05) were not statistically significantly different. Postoperative bleeding was lower (759 versus 967 ml, p=0.032) in the periods with RSMB. Patients receiving RSMB were less transfused with allogenic blood and had less postoperative drainage, while the frequency of observed postoperative complications was not different from patients who did not receive RSMB.

    The aim of this study was to audit the blood transfusion practice throughout the Epworth Healthcare Hospitals for patients undergoing primary total hip replacement (THR). We determined if blood-saving techniques were having an impact on the risk of allogenic blood transfusion and which patients were at risk of receiving allogenic blood transfusion. This study uses a retrospective audit of 787 patients who had undergone primary THR surgery at three Melbourne hospitals: Epworth Richmond, Epworth Eastern and Epworth Freemasons in 2010. Patient demographics, transfusion requirements and blood-conserving techniques were recorded. One hundred and eighty (23%) patients received allogenic blood transfusion and 18 (2.3%) patients received autologous blood transfusion. On multivariate analysis, preoperative anaemia (odds ratio (OR) 4.7, P blood transfusion. Use of spinal anaesthetic was found to be associated with lower risk of transfusion (OR 0.6, P = 0.0180) compared with general anaesthetic alone. Cell saver, acute normovolaemic haemodilution and re-infusion drain tube usage did not have a significant impact on reducing the risk of allogenic blood transfusion. Identification of patients at risk of blood transfusion, correction of preoperative anaemia and a restrictive transfusion policy are important factors to consider in effective perioperative blood management. © 2015 Royal Australasian College of Surgeons.

    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.

  20. Improving blood safety: Errors management in transfusion medicine

    Directory of Open Access Journals (Sweden)

    Bujandrić Nevenka

    2014-01-01

    Full Text Available Introduction. The concept of blood safety includes the entire transfusion chain starting with the collection of blood from the blood donor, and ending with blood transfusion to the patient. The concept involves quality management system as the systematic monitoring of adverse reactions and incidents regarding the blood donor or patient. Monitoring of near-miss errors show the critical points in the working process and increase transfusion safety. Objective. The aim of the study was to present the analysis results of adverse and unexpected events in transfusion practice with a potential risk to the health of blood donors and patients. Methods. One-year retrospective study was based on the collection, analysis and interpretation of written reports on medical errors in the Blood Transfusion Institute of Vojvodina. Results. Errors were distributed according to the type, frequency and part of the working process where they occurred. Possible causes and corrective actions were described for each error. The study showed that there were not errors with potential health consequences for the blood donor/patient. Errors with potentially damaging consequences for patients were detected throughout the entire transfusion chain. Most of the errors were identified in the preanalytical phase. The human factor was responsible for the largest number of errors. Conclusion. Error reporting system has an important role in the error management and the reduction of transfusion-related risk of adverse events and incidents. The ongoing analysis reveals the strengths and weaknesses of the entire process and indicates the necessary changes. Errors in transfusion medicine can be avoided in a large percentage and prevention is costeffective, systematic and applicable.

    Neonatal hemochromatosis is a rare congenital disorder of the liver associated to a poor prognosis. Liver transplantation is often required, since no effective medical treatment has been found. Despite mounting evidence of an alloimmune etiology of this condition, exchange transfusion has never been proposed as a specific treatment for neonatal hemochromatosis. Here we describe two siblings affected by neonatal hemochromatosis. The first, a female, died at 18 days of severe coagulopathy and acute renal failure, diagnosed as affected by neonatal hemochromatosis only when the second sibling was suspected as being affected by the same disease. The second child showed a rapidly worsening coagulopathy which was treated with two exchange transfusions, followed by rapid clinical and laboratory improvement, before reaching a definite diagnosis of neonatal hemochromatosis. He is healthy at present after a follow-up of 12 months. Although exchange transfusion has never been considered as treatment for neonatal hemochromatosis, this case suggests that it could be a feasible treatment option for children affected by this disease, as for other alloimmune conditions.

    Blood transfusion in rural sub-Saharan Africa presents special challenges. Transfusions are primarily given for emergencies--life-threatening blood loss or anemia; blood is usually collected from family or replacement donors; and facilities to store an adequate reserve in a hospital bank are constrained. We report the everyday and organizational practices in a medium-sized district hospital in Northern Ghana. Information and data on blood transfusion practices at West Gonja Hospital, Damongo, were available from the laboratory reports, from day books and workbooks, and from direct observation in the following four areas: blood collection and blood donors; blood donation testing; blood storage and logistics; and clinical transfusion practice, adverse events, and follow-up. The hospital serves a rural community of 86,000. In 2009, a total of 719 units of whole blood were collected, a rate of 8.36 units per 1000 population. All donors were family or replacement donors. Positivity rates for infectious disease markers were 7.5% (64/853) for hepatitis B surface antigen, 6.1% (50/819) for hepatitis C virus, 3.9% (33/846) for human immunodeficiency virus, and 4.7% (22/468) for syphilis. Supply of laboratory materials was sometimes problematic, especially for temperature-critical materials. Difficulties in sample labeling, storage of blood and laboratory supplies, and disposal of waste were also incurred by operational, material, and financial constraints. Follow-up for outcomes of transfusion is not currently feasible. The operational, demographic, and financial environment pertaining in a rural hospital in Northern Ghana differs substantially from that in which much of current blood transfusion practice and technology evolved. Considerable effort and innovation will be needed to address successfully the challenges posed. © 2012 American Association of Blood Banks.

    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.

    ABSTRACT Previous experiments carried out in a sheep scrapie model demonstrated that the transfusion of 200 μl of prion-infected whole blood has an apparent 100% efficacy for disease transmission. These experiments also indicated that, despite the apparent low infectious titer, the intravenous administration of white blood cells (WBC) resulted in efficient disease transmission. In the study presented here, using the same transmissible spongiform encephalopathy (TSE) animal model, our aim was to determine the minimal number of white blood cells and the specific abilities of mononucleated cell populations to transmit scrapie by the transfusion route. Our results confirmed that the transfusion of 100 μl, but not 10 μl, of fresh whole blood collected in asymptomatic scrapie-infected donor sheep can transmit the disease. The data also show that the intravenous administration of 105 WBCs is sufficient to cause scrapie in recipient sheep. Cell-sorted CD45R+ (predominantly B lymphocytes), CD4+/CD8+ (T lymphocytes), and CD14+ (monocytes/macrophages) blood cell subpopulations all were shown to contain prion infectivity by bioassays in ovine PrP transgenic mice. However, while the intravenous administration of 106 CD45+ or CD4+/8+ living cells was able to transmit the disease, similar numbers of CD14+ cells failed to infect the recipients. These data support the contention that mononucleated blood cell populations display different abilities to transmit TSE by the transfusion route. They also represent an important input for the risk assessment of blood-borne prion disease transmission and for refining the target performance of leukoreduction processes that currently are applied to mitigate the transmission risk in transfusion medicine. IMPORTANCE Interindividual variant Creutzfeldt-Jakob disease (vCJD) transmission through blood and blood-derived products is considered a major public health issue in transfusion medicine. Over the last decade, TSE in sheep has emerged as a

    The effect of blood transfusions on the electrolyte, metabolic and hemodynamic status of 31 patients undergoing major laparotomies was studied. Two groups were compared: Group I, 11 patients receiving continuous intraoperative blood transfusions exceeding 5 units at a rate over 0.3 ml/kg/min, and Group II, 20 patients receiving transfusions of 1-5 units at a rate below the limit. Transiently increased potassium values (5.2 +/- 0.3 mmol/l) were found in Group I during the rapid transfusion phase. The difference was statistically significant (P less than 0.05) when compared to Group II (4.3 +/- 0.2 mmol/l). There was also a significant correlation (r = 0.64; P less than 0.05) between the increase in serum potassium concentrations and the respective potassium load caused by the blood transfused. Most of the hyperpotassemic patients had surgery of the abdominal aorta. During the rapid transfusion, the patients in Group I had significantly lower concentrations of serum ionized calcium (P less than 0.05) and higher central venous pressures (P less than 0.05), but more periods of hypotension when compared to Group II. After the transfusion the massively transfused patients had slight metabolic alcalosis, the BE and pH differing significantly (P less than 0.05) from the values of Group II. It is concluded that hyperpotassemia may occur during rapid transfusions (over 0.4 ml/kg/min) of stored blood, especially in patients undergoing surgery of the abdominal aorta, even without simultaneous shock, acidosis or hypothermia. Calcium administration may be of benefit especially in situations where combined hyperpotassemia and hypocalcemia reduce the myocardial performance.

    Of the 21 million blood components transfused in the United States during 2011, approximately 1 in 414 resulted in complication [1]. Two complications in particular, transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), are especially concerning. These two alone accounted for 62% of reported transfusion-related fatalities in 2013 [2]. We have previously developed a set of machine learning base models for predicting the likelihood of these adverse reactions, with a goal towards better informing the clinician prior to a transfusion decision. Here we describe recent work incorporating ensemble learning approaches to predicting TACO/TRALI. In particular we describe combining base models via majority voting, stacking of model sets with varying diversity, as well as a resampling/boosting combination algorithm called RUSBoost. We find that while the performance of many models is very good, the ensemble models do not yield significantly better performance in terms of AUC.

    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 Background/Aim. Anemia is one of the most frequent hematology disorders in patients with malignant diseases. It has a great influence on reduction of the quality of life, so it requires early diagnosis and an adequate treatment. The aim of this study was to present and analyze the treatment of anemia using red blood cell transfusions in patients with malignancies, to analyze adequate use of red blood cell transfusions according to hemoglobin concentration, and also the influence of the treatment of malignant disease on the level of anemia and use of red blood cells transfusion. Methods. This retrospective analysis included the data on the use of red blood cells in Oncological Clinic of Clinical Center Niš in a period from the 1st January 2008 to the 31st December 2008. Results. None of the patients received the whole blood. In this period, 735 patients received 1,006 units of red blood cells (red blood cell concentrate, resuspended, washed, filtered. An average use of red blood cell transfusion was 1.37 unit per oncological patient who received transfusion. The use of red blood cell units was adequate (87.60% of patients received transfusion of red cells when Hgb < 80 g/L. During radio- and chemotherapy we noticed a decrease of hematological parameter values. The patients of the experimental group were dependant on red blood cells transfusion. Statistically, a significant decrease of hemoglobin level was observed in patients treated only with radiotherapy who are the greatest consumers of red blood cells. Two patients were registered who more likely to have febrile nonhemolytic transfusion reactions. Posttransfusion alloimmunization occurred in 0.68% of the patients. Conclusion. The use of red blood cells in oncological patients is in compliance with the up to date tendencies and recommendations published in clinical guidelines. For the purpose of efficient transfusion support in patients with malignant diseases, we have to follow the newest

    Application of blood and blood components throughout decades is very successful and mostly safe procedure in patients' therapy. However, it may lead to unfavourable effects, such as transfusion reactions. In the period from 2000 to 2009, 180 transfusion reactions were reported at the Department of Clinical Transfusion of the Service for Blood Transfusion of Vojvodina in Novi Sad. The aetiology of transfusion reactions was determined by examining pre-transfusion and post-transfusion sample of patient's blood and by examining the unit of blood component that induced reaction. Out of 180 reported transfusion reactions, 98 (54.4%) were febrile non-haemolytic transfusion reactions, 69 (38.3%) allergic reactions and 2 (1.11%) haemolytic reactions. Blood components that caused most of transfusion reactions were erythrocytes (62.4%), fresh frozen plasma (11.2%) and platelets (14.4%). All patients underwent multiple transfusions. The fact that only 0.13% transfusion reactions were reported, compared with data from literature (2-15%), points to the lack of regular reporting of transfusion reactions, as well as the fact that there is only one report of delayed transfusion reaction. To improve and make blood transfusion safer it is necessary to respect all pre-transfusion procedures, constant follow up of blood transfusion must be done and patients with diagnosed non-haemolytic transfusion reaction should be given leukocyte reduced blood components.

    In the field of orofacial surgery, a red blood cell transfusion (RBCT) is occasionally required during double jaw and oral cancer surgery. However, the question remains whether the effect of RBCT during the perioperative period is beneficial or harmful. The answer to this question remains challenging. In the field of orofacial surgery, transfusion is performed for the purpose of oxygen transfer to hypoxic tissues and plasma volume expansion when there is bleeding. However, there are various risks, such as infectious complications (viral and bacterial), transfusion-related acute lung injury, ABO and non-ABO associated hemolytic transfusion reactions, febrile non-hemolytic transfusion reactions, transfusion associated graft-versus-host disease, transfusion associated circulatory overload, and hypersensitivity transfusion reaction including anaphylaxis and transfusion-related immune-modulation. Many studies and guidelines have suggested RBCT is considered when hemoglobin levels recorded are 7 g/dL for general patients and 8-9 g/dL for patients with cardiovascular disease or hemodynamically unstable patients. However, RBCT is occasionally an essential treatment during surgeries and it is often required in emergency cases. We need to comprehensively consider postoperative bleeding, different clinical situations, the level of intra- and postoperative patient monitoring, and various problems that may arise from a transfusion, in the perspective of patient safety. Since orofacial surgery has an especially high risk of bleeding due to the complex structures involved and the extensive vascular distribution, measures to prevent bleeding should be taken and the conditions for a transfusion should be optimized and appropriate in order to promote patient safety.

    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.

    Plasma obtained via whole blood donation processing or via apheresis technology can either be transfused directly to patients or pooled and fractionated into plasma protein products that are concentrates of 1 or more purified plasma protein. The evidence base supporting clinical efficacy in most of the indications for which plasma is transfused is weak, whereas high-quality evidence supports the efficacy of plasma protein products in at least some of the clinical settings in which they are used. Transfusable plasma utilization remains composed in part of applications that fall outside of clinical practice guidelines. Plasma contains all of the soluble coagulation factors and is frequently transfused in efforts to restore or reinforce patient hemostasis. The biochemical complexities of coagulation have in recent years been rationalized in newer cell-based models that supplement the cascade hypothesis. Efforts to normalize widely used clinical hemostasis screening test values by plasma transfusion are thought to be misplaced, but superior rapid tests have been slow to emerge. The advent of non-vitamin K-dependent oral anticoagulants has brought new challenges to clinical laboratories in plasma testing and to clinicians needing to reverse non-vitamin K-dependent oral anticoagulants urgently. Current plasma-related controversies include prophylactic plasma transfusion before invasive procedures, plasma vs prothrombin complex concentrates for urgent warfarin reversal, and the utility of increased ratios of plasma to red blood cell units transfused in massive transfusion protocols. The first recombinant plasma protein products to reach the clinic were recombinant hemophilia treatment products, and these donor-free equivalents to factors VIII and IX are now being supplemented with novel products whose circulatory half-lives have been increased by chemical modification or genetic fusion. Achieving optimal plasma utilization is an ongoing challenge in the interconnected

    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

    This cross-sectional, observational study was carried out among the blood receiving patients conducted in the Department of Transfusion Medicine, Bangabandhu Sheikh Mujib Medical University from April 2008 to August 2009, over 126 purposively selected, to evaluate the extent of awareness about hazards of blood transfusion among the blood recipient. In this study 74.1% of male and 73.3% of female respondents had correct knowledge of blood transfusion (p>0.05). In literate group 85(91.4%) had knowledge about blood donation and transfusion compared to 8(8.6%) in illiterate group with significant statistical difference (p=0.001). Different misconception and lack of awareness about safe blood transfusion is present among people receiving blood and blood products. Illiterate persons have significant less level of knowledge about safe blood transfusion. So the number of educational programs on blood-donation should be expanded and transmitted to encourage possible receivers to take blood from nonprofessional volunteer donor and to carry out relevant screening tests before receiving blood products. Furthermore, they should know that all measures besides screening tests are implemented by blood banks to ensure that blood donation is safe for donors and that transfusion of the donated blood is safe for recipients.

    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.

    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 Public concerns regarding the safety of blood have prompted reconsideration of the use of allogeneic blood (blood from an unrelated donor) transfusion and a range of techniques designed to minimise transfusion requirements. Objectives To examine the efficacy of desmopressin acetate (1-deamino-8-D-arginine-vasopressin) in reducing peri-operative blood loss and the need for red blood cell (RBC) transfusion in patients who do not have congenital bleeding disorders. Search methods We identified studies by searching CENTRAL (The Cochrane Library 2008, Issue 1), MEDLINE (1950 to 2008), EMBASE (1980 to 2008), the Internet (to May 2008), and bibliographies of published articles. Selection criteria Controlled parallel-group trials in which adult patients scheduled for non-urgent surgery were randomised to desmopressin (DDAVP) or to a control group that did not receive DDAVP treatment. Trials were eligible for inclusion if they reported data on the number of patients exposed to allogeneic red cell transfusion or the volume of blood transfused. Data collection and analysis Primary outcomes were: the number of patients exposed to allogeneic red blood cell (RBC) transfusion, and the amount of blood transfused. Other outcomes measured were: blood loss, re-operation for bleeding, post-operative complications (thrombosis, myocardial infarction, stroke), mortality, and length of hospital stay. Treatment effects were pooled using a random-effects model. Main results Nineteen trials that included a total of 1387 patients reported data on the number of patients exposed to allogeneic RBC transfusion. DDAVP did not significantly reduce the risk of exposure to allogeneic RBC transfusion (relative risk (RR) 0.96, 95% confidence interval (CI) 0.87 to 1.06). However, the use of DDAVP significantly reduced total blood loss (weighted mean difference (WMD) −241.78 ml, 95% CI −387.55 to −96.01 ml). Although DDAVP appeared to reduce the overall volume of allogeneic blood

    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.

    Proposed changes to ISO 1135-4 will require that blood transfusion administration sets are demonstrated by the manufacturers to be suitable for the range of cellular and plasma blood components for which they are designated. To design a test protocol to asses the depletion of the blood components by transfusion sets and damage and activation of blood components during their passage through the set. Transfusion giving sets (CareFusion Ref no. 60895 180311 and Fresenius Ref no. 2900032) were assessed by comparing samples of the blood component taken prior to and after passage through the transfusion set in strict accordance with the manufacturer's instructions. As well as depletion of red cells, platelets and FVIIIc, the following markers of damage/activation were assessed: red cells-supernatant haemolysis and potassium; FFP-prothrombin fragments 1 and 2 and fibrinopeptide A and platelets-pH, CD62P, CD63 and sP-selectin. The CareFusion and the Fresenius transfusion sets gave less than 5% depletion of blood components and caused negligible and clinically insignificant effects on red cells, platelet concentrates and FFP. A practical test protocol has been established to assess the depletion, damage to and activation of the key constituents of commonly requested blood components. This protocol would provide a valuable addition to ISO 1135-4 in assuring the suitability of transfusion sets. © 2013 The Authors. Transfusion Medicine © 2013 British Blood Transfusion Society.

  8. Anemia and red blood cell transfusion in neurocritical care

    2009-01-01

    Introduction Anemia is one of the most common medical complications to be encountered in critically ill patients. Based on the results of clinical trials, transfusion practices across the world have generally become more restrictive. However, because reduced oxygen delivery contributes to 'secondary' cerebral injury, anemia may not be as well tolerated among neurocritical care patients. Methods The first portion of this paper is a narrative review of the physiologic implications of anemia, hemodilution, and transfusion in the setting of brain-injury and stroke. The second portion is a systematic review to identify studies assessing the association between anemia or the use of red blood cell transfusions and relevant clinical outcomes in various neurocritical care populations. Results There have been no randomized controlled trials that have adequately assessed optimal transfusion thresholds specifically among brain-injured patients. The importance of ischemia and the implications of anemia are not necessarily the same for all neurocritical care conditions. Nevertheless, there exists an extensive body of experimental work, as well as human observational and physiologic studies, which have advanced knowledge in this area and provide some guidance to clinicians. Lower hemoglobin concentrations are consistently associated with worse physiologic parameters and clinical outcomes; however, this relationship may not be altered by more aggressive use of red blood cell transfusions. Conclusions Although hemoglobin concentrations as low as 7 g/dl are well tolerated in most critical care patients, such a severe degree of anemia could be harmful in brain-injured patients. Randomized controlled trials of different transfusion thresholds, specifically in neurocritical care settings, are required. The impact of the duration of blood storage on the neurologic implications of transfusion also requires further investigation. PMID:19519893

    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.

    Full Text Available Anemia is an important condition that is found in the internal medicine, either in humans and animals, especially in critically ill patients. The clinical signs of anemia are usually related to a poor tissue oxygenation or the compensatory mechanisms associated with it. Blood transfusion aims to prevent hypoxic damage in critically ill patients. However, once the blood transfusion is associated to some risks, it should just be done if really necessary. Several factors influence blood transfusion decision. The aim of this study was to review the major studies about transfusion triggers. Among laboratory tests, the hemoglobin (Hb is the main trigger but it depends on patient age and concomitant disease. In addition, electrocardiogram (ECG and serum lactate with Hb can help to decide when to transfuse. A anemia é uma importante afecção encontrada na medicina e na clínica de animais de companhia, principalmente nos pacientes críticos. As alterações clínicas da anemia geralmente estão relacionadas à menor oxigenação dos tecidos ou aos mecanismos compensatórios a ela associados. A transfusão sanguínea tem o objetivo de impedir os danos de hipóxia causados pela anemia em pacientes criticamente enfermos. Porém, uma vez que a transfusão está sujeita a diversos riscos, ela só deve ser realizada quando realmente necessária. Diversos fatores influenciam a decisão para realização da transfusão sanguínea. O objetivo deste trabalho foi fornecer uma revisão dos principais estudos realizados sobre possíveis gatilhos transfusionais. Entre os exames laboratoriais, o valor de hemoglobina (Hb é o principal gatilho, variando de acordo com idade do paciente e doenças concomitantes. Além disso, o eletrocardiograma e a dosagem sérica de lactato, associados à Hb, podem ajudar na decisão de quando transfundir.

    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.

    Syphilis is one of the mandatory transfusion transmissible infections to be tested for in any unit of blood for homologous transfusion. The paucity of voluntary blood donors in Nigeria has compelled health care providers to rely on paid and family replacement donors for blood. This study was carried out to determine the prevalence of syphilis among blood donors at a centralized Transfusion Service in North Central Nigeria. Records of blood donors at the North Central Zonal Centre of the National Blood Transfusion Service in Jos, from April 2007 to March 2010 were analyzed for sero-positivity to Treponema pallidum and co-infections with other transfusion transmissible infections. 9,500 blood donors where received at the Transfusion Service Centre in Jos within the study period. The overall prevalence of syphilis among blood donors was 0.9%. New voluntary non remunerated donors constituted 69.9% with a syphilis sero-positivity of 0.9% and 0.2% co-infection. Retained voluntary non remunerated donors accounted for 19.5% with syphilis sero-positivity of 0.2%. Family replacement donors made up 10.6% of total blood units screened with a 2.0% anti-syphilis positive reaction and 1.0% co-infection. The prevalence of syphilis among blood donors in a centralized transfusion service may be low.

    To explore the effects of blood transfusion on the vital signs and heart function in preterm infants with anemia. A total of 40 anemic preterm infants with gestational age less than 34 weeks who accepted blood transfusion one week after birth were enrolled for a prospective cohort study. Left ventricular ejection fraction (LVEF), fractional shortening (FS), stroke volume (SV), and cardiac output (CO) were determined with portable ultrasonic equipment before blood transfusion and within 24 hours after blood transfusion. Apnea was detected and the times of apnea were recorded within 24 hours before and after blood transfusion. The resting body temperature and blood pressure were also determined before and after blood transfusion. Additionally the resting heart rate, respiratory rate, and transcutaneous oxygen saturation were recorded within 4 hours before and after blood transfusion. The heart rate and respiratory rate decreased significantly within 4 hours after blood transfusion (Pblood transfusion, and nobody had apnea within 24 hours after blood transfusion. The systolic pressure, diastolic pressure, mean arterial pressure, and body temperature showed no significant changes after blood transfusion (P>0.05), and the LVEF, SV, CO, and FS showed no significant changes after blood transfusion as well (P>0.05). Blood transfusion can improve the clinical symptoms and shows no significant effect on the heart function in preterm infants with anemia.

    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.

    Preoperative anemia may be treated with a blood transfusion. Both are associated with adverse outcomes in various surgical procedures, but this has not been clearly elucidated in surgery for cerebral aneurysms. In this study the authors assessed the association of preoperative anemia and perioperative blood transfusion, separately, on 30-day morbidity and mortality in patients undergoing open surgery for ruptured and unruptured intracranial aneurysms. The authors identified 668 cases (including 400 unruptured and 268 unruptured intracranial aneurysms) of open surgery for treatment of intracranial aneurysms in the 2006-2012 National Surgical Quality Improvement Program, a validated and reproducible prospective clinical database. Anemia was defined as a hematocrit level less than 39% in males and less than 36% in females. Perioperative transfusion was defined as at least 1 unit of packed or whole red blood cells given at any point between the start of surgery to 72 hours postoperatively. The authors separately compared surgical outcome between patients with (n = 198) versus without (n = 470) anemia, and those who underwent (n = 78) versus those who did not receive (n = 521) a transfusion, using a 1:1 match on propensity score. In the matched cohorts, all observed covariates were comparable between anemic (n = 147) versus nonanemic (n = 147) and between transfused (n = 67) versus nontransfused patients (n = 67). Anemia was independently associated with prolonged hospital length of stay (LOS; odds ratio [OR] 2.5, 95% confidence interval [CI] 1.4-4.5), perioperative complications (OR 1.9, 95% CI 1.1-3.1), and return to the operating room (OR 2.1, 95% CI 1.1-4.5). Transfusion was also independently associated with perioperative complications (OR 2.4, 95% CI 1.1-5.3). Preoperative anemia and transfusion are each independent risk factors for perioperative complications in patients undergoing surgery for cerebral aneurysms. Perioperative anemia is also associated with

    Full Text Available Introduction. Intraoperative blood salvage (IBS is a procedure involving recovering blood looses during surgery and reinfusing it into the patient with a purpose to reduce the perioperative morbidity and mortality associated with complications after administration of allogenic transfusion (AT. The aim of this study was to investigate whether the IBS reduces the need for allogenic transfusion requirements and for non-invasive ventilation (NIV and/or oxygen supplementation and whether it was associated with decreased levels of inflammatory markers following abdominal aortic aneurysm (AAA surgery. Methods. Throughout the period from February to October 2010, 51 patients underwent both elective and emergency AAA surgery. During the study period, IBS using 'Haemonetics cell saver 5+' was applied in 24 (46.2% patients (CS group, while it wasn't used in 27 (51.9% cases (NCS group. Values of certain inflammatory biomarkers included: white blood cell count (WBCC, C-reactive protein (CRP, procalcitonin (PCT and fibrinogen were monitored during the first 48 hours postoperatively. Secondary outcome measures icluded: the need for allogenic transfusion and for non-invasive ventilation (NIV and/or oxygen supplementation. Results. The requirements for intra and postoperative alogenic red blood cells transfusions was significantly higher in patients from NCS group compared to patients in CS group (3.63 vs. 0.58 units per patient; p< 0.001. Non-invasive respiratory support was more frequently used in patient from NCS group (4/27 compared to those in CS (1/24 group but difference was not statistically significant (p=0.17. The postoperatively average WBCC was significantly higher among patients in NCS group compared to those from CS group (12.89 x 109 vs. 10.44 x109; p=0.014. Also CRP plasma levels postoperatively were significantly higher in NCS group compared to CS group (67.18 mg.L-1 vs. 47.54 mg.L-1; p=0.015. Conclusion(s. The usage of intraoperative blood

    The emergence of transfusion transmitted infection (TTI) especially HIV/AIDS has created a huge obstacle in ensuring blood safety. To assess the situation in Eritrea, we carried out a retrospective study of 29,501 blood donors for the prevalence of TTI's i.e. HIV, HBV, HCV and Syphilis. The study population included all donors who donated blood from January 2006 to November 2009. The data was collected from the National Blood Transfusion Services (NTBS) of Eritrea and includes category of donor and result for TTI markers. A total of 29,501 units of blood were collected from 23,385(79%) voluntary blood donors and the rest 6,116(21%) units were collected from family replacement donors. The over all prevalence of TTI's were 3.8% with 3.5% in voluntary blood donors and 5.1% in family replacement donors. The sero-prevalence for TTI markers were 0.18% HIV, 2.58% HBV, 0.57% HCV and 0.49% Syphilis. In conclusion, even if the TTI prevalence rate among Eritrean blood donors is low, ensuring blood safety has a long way to go.

    It is established that blood transfusions will promote sensitization to human leucocyte antigen (HLA) antigens, increase time spent waiting for transplantation and may lead to higher rates of rejection. Less is known about how perioperative blood transfusion influence patient and graft outcome. This study aims to establish if there is an association between perioperative blood transfusion and graft or patient survival.

    The objective of the study was to investigate the splanchnic blood flow velocity and oximetry response to blood transfusion in preterm infants according to postnatal age. Preterm infants receiving blood transfusion were recruited to three groups: 1-7 (group 1; n = 20), 8-28 (group 2; n = 21) and ≥29 days of life (group 3; n = 18). Superior mesenteric artery (SMA) peak systolic (PSV) and diastolic velocities were measured 30-60 min pre- and post-transfusion using Doppler ultrasound scan. Splanchnic tissue haemoglobin index (sTHI), tissue oxygenation index (sTOI) and fractional tissue oxygen extraction (sFTOE) were measured from 15-20 min before to post-transfusion using near-infrared spectroscopy. The mean pretransfusion Hb in group 1, 2 and 3 was 11, 10 and 9 g/dl, respectively. The mean (SD) pretransfusion SMA PSV in group 1, 2 and 3 was 0·63 (0·32), 0·81 (0·33) and 0·97 (0·40) m/s, respectively, and this did not change significantly following transfusion. The mean (SD) pretransfusion sTOI in group 1, 2 and 3 was 36·7 (19·3), 44·6 (10·4) and 41·3 (10·4)%, respectively. The sTHI and sTOI increased (P transfusion in all groups. On multivariate analysis, changes in SMA PSV and sTOI following blood transfusion were not associated with PDA, feeding, pretransfusion Hb and mean blood pressure. Pretransfusion baseline splanchnic tissue oximetry and blood flow velocity varied with postnatal age. Blood transfusion improved intestinal tissue oxygenation without altering mesenteric blood flow velocity irrespective of postnatal ages. © 2016 International Society of Blood Transfusion.

    Thalassemia is a congenital hemolytic disease caused by defective globin synthesis treated by blood transfusion. Transfusion-transmitted infections still make a great challenge in the management of patients with thalassemia major. The most important worldwide transfusion-transmitted infections are hepatitis B virus (HBV), hepatitis C virus (HCV) and HIV. The objective of this study is to update the prevalence of the three major transfusion-transmitted infections HCV, HBV and HIV among thalassemic patients followed up in the Hematology Department, Children Hospital, Cairo University. The study included 174 multitransfused thalassemic patients (162 major and 12 intermedia), registered at the Pediatric Hematology Clinic, Cairo University. Their age ranged from 2 to 27 years with a mean of 11.26 ± 5.4 years. Patients were subjected to full history taking, stressing on history of blood transfusions (onset, frequency and duration) at a single or multiple centers and abdominal examination. Laboratory investigations including complete blood count, aminotransferases (aspartate aminotransferase and alanine aminotransferase), ferritin and viral markers of HBV surface antigen (HBsAg), HCV antibodies (anti-HCV) and anti-HIV were assayed for all cases by a third-generation ELISA method. HCV PCR was performed for 75 cases. Of the 174 patients, none of them were HBsAg and anti-HIV positive. However, 90 patients were anti-HCV positive (51.7%). HCV PCR was positive in 56 patients (74.3%) of the 75 with positive antibody tested. HCV antibody positivity is statistically significant with age of the patient, serum ferritin and liver transaminases (P age and serum ferritin (P attention and efforts to challenge. There is a dramatic decrease in the prevalence of HBV infection over the last decade, thanks to mass compulsory vaccination and blood screening. HIV infection does not represent a problem owing to very low population prevalence.

    One of the objectives of the NHS reforms is to improve customer focus within the health service. In a study to assess the quality of customer service provided by the Edinburgh and South East Scotland Blood Transfusion Service a 19 item questionnaire survey of the main clinical users of the service was performed to ascertain their satisfaction, measured on a 5 point anchored scale, with important aspects of the service, including medical consultation, diagnostic services, blood and blood components or products and their delivery, and general satisfaction with the service. Of 122 clinicians in medical and surgical disciplines in five hospitals in Edinburgh, 72 (59%) replied. Fourteen (22%) indicated dissatisfaction with any aspect of the medical consultation service, owing to inadequate follow up of clinical contacts and unsatisfactory routing of incoming calls. Diagnostic services were criticised for the presentation, communication, and interpretation of results. The restricted availability of whole blood, the necessity to order platelets and plasma through the duty blood transfusion service doctor, and the use of a group and screen policy, attracted criticism from a small number of clinicians. Ten of 68 respondents expressed dissatisfaction with delivery of blood and components to the wards and theatres. The findings indicate that the clinicians served by this blood transfusion service are largely satisfied with the service. Changes are being implemented to improve reporting of laboratory results and measures taken to improve liaison with clinicians.

  15. The Precautionary Principle and the Tolerability of Blood Transfusion Risks.

    Tolerance for blood transfusion risks is very low, as evidenced by the implementation of expensive blood tests and the rejection of gay men as blood donors. Is this low risk tolerance supported by the precautionary principle, as defenders of such policies claim? We discuss three constraints on applying (any version of) the precautionary principle and show that respecting these implies tolerating certain risks. Consistency means that the precautionary principle cannot prescribe precautions that it must simultaneously forbid taking, considering the harms they might cause. Avoiding counterproductivity requires rejecting precautions that cause more harm than they prevent. Proportionality forbids taking precautions that are more harmful than adequate alternatives. When applying these constraints, we argue, attention should not be restricted to harms that are human caused or that affect human health or the environment. Tolerating transfusion risks can be justified if available precautions have serious side effects, such as high social or economic costs.

    Full Text Available BACKGROUND: Transfusion requests are always more than the supply due to advances in health care delivery . Injudicious use of whole blood and blood components strains the transfusion services. This mandates the proper analysis of real need of transfusion and the discard of this scarce resource. MATERIALS & METHODS: Total 31143 voluntary and replacement donors donated blood during January 2012 to December 2014 in blood bank of tertiary care Government hospital in Central India. The donors record, transfusion transmitted infections (TTI testing record, component preparation record & discard record during the same period were screened for analysis. RESULT: Out of total 31143 blood collection during study period TTI positive blood were 377 (1.21% comprising of 13.4% of total discarded blood bags. Components prepared 19545 and discarded 1610 (8.2%. Among components discarded most common units were platelets due to date expiry followed by FFP discarded due to leakage of bag. CONCLUSION: Analysis of reasons of discard of whole blood and blood components helps in forming policies to reduce the gap between demand and supply at local as well as national level

    A serologic study of Chagas disease was performed in 110 patients submitted to chronic hemodialisis and blood transfusions. Immunofluorescence antibody testing (IgG and IgM) was positive in 6 out of 62 patients receiving multiple blood transfusions (9.7%), but negative in all 48 subjects without transfusions. Thus, repeated blood transfusion is a significant risk for T cruzi infection in chronic hemodialized patients.

    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.

    1986-01-01

    This article reviews some of the epidemiologic aspects of transmission of LAV through transfusion of blood and blood products in the light of data available until late December 1985 in France, Europe and the United States. As of December 1985, blood transfusion has been considered the etiologic factor in 2.58% of the 15,172 cases of AIDS reported in the USA and in 5.6% of 1,573 cases of AIDS registered in Europe. Whole blood, cellular blood components and plasma derivatives except Albumin and immunoglobulins have been incriminated in 1.75 to 2.22 of the above percentages. Hemophiliacs under long term therapy by factor VIII and factor IX concentrates (0.83 to 3.36 of the above percentages) represent a highly exposed group when one considers the small proportion of these individuals in the general population (1/10,000 inhabitants). Three preventive measures have been officially implemented in the French transfusion network: self refrainment and deferral of prospective donors belonging to risk factor groups, systematic screening of donated blood for the presence of anti-LAV antibodies and elimination of seropositive units, heat treatment of coagulation factor concentrates to achieve viral inactivation. Information and medical follow up of LAV-contaminated donors thus identified and of their partners represent an important issue among the current public health problems.

    From transfusion point of view, a rare blood is the one which lacks a high-frequency antigen as well as the one who lacks multiple common antigens and such blood donations help in transfusion to those recipients having alloantibodies to corresponding antigens. In India, we have about four such kinds of phenotypes potential enough to pose problems in providing blood to the recipients having these phenotypes. Besides, there are other four kinds of rare bloods that pose seldom problems in blood supply, though some of these may cause problems in interpretation of results on assigning proper blood groups for a person.

    The concentration of extracellular potassium in red blood cell concentrates (RCCs) increases during storage, leading to risk of hyperkalemia. A potassium adsorption filter (PAF) can eliminate the potassium at normal blood transfusion. This study aimed to investigate the potassium adsorption capacity of a PAF during rapid blood transfusion. We tested several different potassium concentrations under a rapid transfusion condition using a pressure bag. The adsorption rates of the 70-mEq/l model were 76·8%. The PAF showed good potassium adsorption capacity, suggesting that this filter may provide a convenient method to prevent hyperkalemia during rapid blood transfusion. © 2015 International Society of Blood Transfusion.

    1987-04-01

    About 3.2% of worldwide cases of acquired immunodeficiency syndrome (AIDS) have been attributed to the transfusion of whole blood and plasma products. An estimated 66% of recipients of blood and blood products infected with human immunodeficiency virus (HIV) develop HIV seropositivity. This calls attention to the need to develop strict guidelines to protect clients of blood transfusion services. Toward this end, the International Society of Blood Transfusion has made the following recommendations: donors belonging to high-risk groups for HIV infection should be excluded from donating blood; blood and plasma products should be screened for antibodies to HIV through laboratory tests with demonstrated reproducibility and specificity; donors should be informed that their blood will be screened and procedures for confidential notification of any positive results should be outlines; it should be clearly stated on the label if a blood product has not been screened for HIV; and viral inactivation, including heat treatment, should be mandatory for the processing of all plasma products. Interns of the situation in India, the director of the Institute of Immunohematology in Bombay has made these recommendations: the general public should be educated about the fact that the donation of blood cannot lead to AIDS; an effort should be made to obtain blood products from volunteers rather than professional donors or blood banks; donors whose history includes risk factors for HIV infection should have their blood screened; confidentiality must be a guiding principle in all cases; all source material and final plasma products should be screened for antibodies to HIV; and all plasma products should be heat inactivated before sale.

    Multiple studies nationwide and at single hospitals have examined changes over time in the incidence of perioperative red blood cell (RBC) transfusion. However, the cost of RBC transfusions is related to the number of RBC units transfused, not to the incidence. We evaluate whether the readily available incidence of RBC transfusion can be used as a valid surrogate measure. Observational retrospective study. One tertiary, academic hospital. 394,789 cases of 1885 procedures over N=42 quarters of the year. None. Incidence and number of RBC units transfused intraoperatively. The number of RBC units transfused per case did not follow a Poisson distribution, confirming that the number of units and incidence of transfusion are not interchangeable for analyzing decisions by case.

    Understanding propofol distribution in blood is important for optimizing drug usage during TIVA. We studied changes in the propofol concentration in plasma and formed blood elements separated from blood samples taken before and after transfusion of blood cells to patients during TIVA with propofol. Twelve patients were studied (ASA I-II). Propofol TIVA was performed at infusion rates of 12-9-6 mg x kg(-1) x h(-1). Fentanyl and pancuronium bromide were administered in fractional doses. After tracheal intubation the lungs were ventilated to normocapnia with oxygen-air mixture (FiO2=0.33). Blood samples for propofol analysis were taken 5 min before and 30 min after blood cell transfusion. At that point the propofol infusion rate was 6 mg x kg(-1) x h(-1). Propofol concentrations were measured by means of HPLC. Blood cell transfusion leads to a change in the propofol level in plasma and formed blood elements. The transfusion process lowers the ratio of the plasma propofol concentration to the propofol concentration in formed blood elements. Formed blood elements show a greater ability to bind propofol after transfusion of 5-15 day erythrocytes.

    Trauma resuscitation has undergone a paradigm shift with new emphasis on the early use of blood products and increased proportions of plasma and platelets. However, it is unclear how this strategy is applied or how effective it is in the elderly population. The study aim is to identify differences in transfusion practices and the coagulopathy of trauma in the elderly. Data was prospectively collected on all consecutive patients that met trauma activation criteria at a Level I trauma centre. Data fields included patient demographics, co-morbidities, injury and resuscitation data, laboratory values, thromboelastography (TEG) results, and outcome measures. Elderly patients were defined as those 55 and older. Propensity-score matched analysis was completed for patients receiving blood product transfusion. Patients were matched by gender, mechanism, injury severity score (ISS), head injury, and time from injury. Total of 628 patients were included, of which 142 (23%) were elderly. Elderly patients were more likely to be female (41% vs. 24%), suffer blunt mechanism of trauma (96% vs. 80%), have higher ISS scores (mean 25.4 vs. 21.6) and mortality (19% vs. 8%). Elderly patients were significantly more likely to receive a blood transfusion (42% vs. 30%), specifically for red cells and plasma. Propensity-matched analysis resulted in no difference in red cell transfusion or mortality. Despite the broad similarities between the matched cohorts, trauma coagulopathy as measured by TEG was less commonly observed in the elderly. Our results suggest that elderly trauma patients are more likely to receive blood products when admitted to a trauma centre, though this may be attributed to under-triage. The results also suggest an altered coagulopathic response to traumatic injury which is partially influenced by increased anticoagulant and antiplatelet medication use in the geriatric population. It is not clear whether the acute coagulopathy of trauma is equivalent in geriatric

    This audit encompassing a six-month period on the current practice of red blood cell transfusion following elective primary total hip arthroplasty showed that the rate of allogeneic blood avoidance was 84.8% for preoperative autologous blood donors and 47.8% for non-donors (p<0.001). Lower preoperative hemoglobin level was associated with an increased allogeneic unit transfusion (p<0.001). The intraoperative use of autologous blood collection and transfusion systems did not reduce the transfusion risk, and the use of the colloid volume expander was associated with a 1.8-fold increased risk of transfusion (p=0.022).

    Allogeneic blood transfusion during liver resection for malignancies has been associated with an increased incidence of different types of complications: infectious complications, tumor recurrence, decreased survival. Even if there is clear evidence of transfusion-induced immunosuppression, it is difficult to demonstrate that transfusion is the only determinant factor that decisively affects the outcome. In any case there are several motivations to reduce the practice of blood transfusion. Th...

    1) Only a very limited amount of all cases of so-called "post-transfusion-hepatitis" (pth) is really due to infectivity of the transfused blood. Regardless of the mostly unknown true source of the infection, the occurrence of "pth" for itself does not qualify the recipient and/or his illness-insurance company for a legitimate action for damages against the blood bank under current West Germany Federal Law. 2) All West German blood banks are obliged by Federal Law to insure themselves against strictly defined damage claims. Their damage-insurance companies are not entitled to pay compensations to the illness-insurance companies of any victim of "pth" without meticulous investigation of the exact circumstances if expenses exceeding the legally defined limitations are included in the premium of damage-insurance charged to the blood banks. 3)Since nearly all inhabitants of West Germany are legally or voluntarily insured against illness, compensations paid by damage-insurance companies to illness-insurance companies are no appropriate means for any cost containment of the latter: The blood banks have no other choice than to calculate the additional premium costs into the costs of the blood units to be debitted to the illness-insurance companies.

    To study the efficacy and safety of double volume exchange transfusion (DVET) in neonates > 1000 g birth weight with severe sepsis. Eighty-three neonates weighing >1000 g with severe sepsis were randomly assigned to DVET or standard therapy (ST) group. Primary outcome was mortality by 14 d from enrollment. A 21 % reduction in mortality, albeit non-significant, by 14 d from enrollment was observed in DVET group in comparison to ST group [RR: 0.79 (95 % C.I 0.45-1.3); p 0.4]. A similar trend in mortality reduction was observed with early mortality and mortality by discharge in DVET group. No difference was observed in normalization of dysfunctional organs by 14 d. Cardiovascular and hematological system benefitted the most, followed by renal dysfunction with DVET. A significant improvement in post DVET IgG, IgA, IgM, C3 and base deficit was observed. No serious adverse effects occurred following DVET. In neonates >1000 g with severe sepsis, DVET was associated with a trend towards decrease in mortality by 14 d from enrollment. A significant improvement in immunoglobulin and complement C3 levels and acid base status were observed following DVET. DVET is a safe procedure in severely sick and septic neonates.

    Full Text Available Aim : This study was designed to find out the factors influencing mortality in trauma patients receiving massive blood transfusion (MBT. Materials and Methods : Records of all patients admitted during December 2007 to November 2008 at a Level I Trauma Center emergency and who underwent massive transfusion (≥10 units of packed red cells in 24 h were retrospectively analyzed. Death during the hospital stay was considered as the study outcome and various demographic, laboratory, and clinical parameters were included as its potential determinants. Statistical Analysis : Bivariate and multivariate logistic regression analyses were done to identify the risk factors associated with mortality. Results : Of the 4054 transfused patients who were admitted to the trauma center during the study period, 71 (1.8% patients underwent massive transfusion. Of this, there were 37 survivors and 34 nonsurvivors (48%. The median overall ISS was 27 (22-34. The patients who died had shorter mean length of hospital stay, shorter mean duration of intensive care unit (ICU stay, and low admission Glasgow Coma Scale (GCS compared to the survivors (P < 0.01. The mean prothrombin time (PT and the mean activated partial thromboplastin time was significantly high (P < 0.01 among nonsurvivors. Total leukocyte count (TLC ≥ 10,000 cells/cubic mm, GCS ≤ 8, the presence of coagulopathy and major vascular surgery were the four independent determinants of mortality in multivariate logistic regression analysis. The FFP:PRBC (fresh frozen plasma:packed red cells ratio and PC:PRBC (platelet concentrate:packed red cells ratio calculated in our study was not statistically significant in correlation to the in hospital mortality. Conclusions : Overall mortality among the MBT patients was comparable with the studies in the literature. Mortality is not affected by the amount of packed red cells given in the first 12 h and the total number of packed red cells transfused. Prospective

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

    Science.gov (United States)

    Rajtar, Małgorzata

    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.

    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

    Hyperfibrinolysis has been observed in patients heavily transfused with solvent/detergent-treated pooled plasma (S/D plasma). We compared coagulation and fibrinolytic variables in blood containing S/D plasma with blood containing fresh-frozen plasma (FFP), with and without α2-antiplasmin or tranexamic acid (TXA) supplementation. Whole blood samples were reconstituted from red blood cells, platelet (PLT) concentrates, and varying mixtures of FFP and S/D plasma. Hematocrit and PLT count of reconstituted whole blood samples were varied. For a subset of runs, α2-antiplasmin or TXA was added to S/D plasma whole blood samples. Thromboelastography (TEG) analysis was performed to assess 50% clot lysis time (CLT 50% ), maximum amplitude (MA), and initial clotting time (R-time). The change in CLT 50% of whole blood as the plasma compartment transitions from FFP to S/D plasma was -52% (95% confidence interval [CI], -60% to -45%; p plasma in whole blood. α2-Antiplasmin and TXA restored clot lysis time in S/D plasma whole blood. Whole blood with S/D plasma has shorter clot lysis times in vitro compared to whole blood with FFP. α2-Antiplasmin and TXA restore clot lysis time of S/D plasma whole blood to that of FFP whole blood. Clinicians should be aware of the decreased clot lysis time associated with S/D plasma transfusion. © 2017 AABB.

    Rationale: Transfusion of erythrocytes stored for prolonged periods is associated with increased mortality. Erythrocytes undergo hemolysis during storage and after transfusion. Plasma hemoglobin scavenges endogenous nitric oxide leading to systemic and pulmonary vasoconstriction. Objectives: We hypothesized that transfusion of autologous blood stored for 40 days would increase the pulmonary artery pressure in volunteers with endothelial dysfunction (impaired endothelial production of nitric oxide). We also tested whether breathing nitric oxide before and during transfusion could prevent the increase of pulmonary artery pressure. Methods: Fourteen obese adults with endothelial dysfunction were enrolled in a randomized crossover study of transfusing autologous, leukoreduced blood stored for either 3 or 40 days. Volunteers were transfused with 3-day blood, 40-day blood, and 40-day blood while breathing 80 ppm nitric oxide. Measurements and Main Results: The age of volunteers was 41 ± 4 years (mean ± SEM), and their body mass index was 33.4 ± 1.3 kg/m2. Plasma hemoglobin concentrations increased after transfusion with 40-day and 40-day plus nitric oxide blood but not after transfusing 3-day blood. Mean pulmonary artery pressure, estimated by transthoracic echocardiography, increased after transfusing 40-day blood (18 ± 2 to 23 ± 2 mm Hg; P transfusing 3-day blood (17 ± 2 to 18 ± 2 mm Hg; P = 0.5). Breathing nitric oxide decreased pulmonary artery pressure in volunteers transfused with 40-day blood (17 ± 2 to 12 ± 1 mm Hg; P Transfusion of autologous leukoreduced blood stored for 40 days was associated with increased plasma hemoglobin levels and increased pulmonary artery pressure. Breathing nitric oxide prevents the increase of pulmonary artery pressure produced by transfusing stored blood. Clinical trial registered with www.clinicaltrials.gov (NCT 01529502). PMID:25162920

    To study the positive distribution rate of Coombs test in patients with clinical anemia and blood transfusion, and its effect on clinical blood transfusion. Seventy patients with hemoglobin level in the normal range were enrolled into control group, while 130 patients with anemia or blood transfusion who' s hemoglobin level was lower comfirmed by micro-column gel antihuman globin detection card and 70 surgical patients with anemia or blood transfusion who' s hemoglobin level was lower comfirmed by micro-column gel anti-human globin card were enrolled into anemia or blood transfusion (A or BT) group. And coomb' s test performed for all the patients, in which the positive patients in Department of Internal Medicine need to be re-typed. Among 70 surgical patients with anemia or blood transfusion, 14 cases were directly detected to be anti-human globine positive with detection rate 20%; among 130 internal medicine patients with anemia or blood transfusion, 54 cases were directly detected to be anti-human globine positive with detection rate 41.4%. Among 270 cases, the highest positive rate (66.7%) was observed in patients with 50-59 g/L of hemoglobin. According to type test, the samples of 54 patients with anemia in Department of Internal Medicine, who were directly selected to be anti-human globin positive, could be divided into anti-C3d(7 cases, accounting for 13.0%), anti-IgG(12 cases accounting for, 22.2%) and anti-C3d+anti-IgG(35 cases, accounting for 64.8%), while according to diseases, the anti-human globin positive ratio was high in tumor cancer, hephropathy and gastroenteropathy patients, and patients in intensive care unit, moreover the blood transfusion frequency of these patients was higher than that of patients with anti-human globin negative(Pblood transfusion, so as to ensure the effectiveness of blood transfusion.

    This study was conducted to evaluate the operative time, blood loss, hemoglobin drop, blood transfusion, and length of hospital stay in orthognathic surgery. A 10-year retrospective analysis was performed on patients who underwent bilateral sagittal split osteotomy (with or without genioplasty), Le Fort I osteotomy (with or without genioplasty), or any combination of these procedures. A total of 271 patients were included. The age range was 17 to 49 years, with a mean age of 24.13 ± 4.51 years. Approximately 62% of patients underwent double-jaw surgery. The most common procedure was bilateral sagittal split with Le Fort I (37%). The average operative time was 3.96 ± 1.25 h. The mean estimated blood loss was 345.2 ± 149.74 mL. Approximately 9% of patients received intraoperative blood transfusion. The mean hemoglobin drop in the non-transfusion cases was 2.38 ± 0.89 g/dL. The mean postoperative hospital stay was 1.85 ± 0.83 days. Only one patient was admitted to the ICU for one night. In orthognathic surgery, blood loss is relatively minor, blood transfusion is frequent, and ICU admission is unlikely. Operative time, blood loss, blood transfusion, and the complexity of the surgical procedure can significantly increase the length of hospital stay. Males may bleed more than females in orthognathic surgery. Hemoglobin drop can be overestimated due to hemodilution in orthognathic surgery, which may influence the decision to use blood transfusion.

    2014-01-01

    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

    Full Text Available Background: Adverse transfusion reactions can cause morbidity and death to patients who receive a blood transfusion. Blood transfusion practice in Mulago Hospital, Kampala, Uganda is analyzed to see if and when these practices play a role in the morbidity and mortality of patients. Materials and Methods: An observational study on three wards of Mulago Hospital. Physicians, paramedics, nurses, medical students and nurse students were observed using two questionnaires. For comparison, a limited observational study was performed in the University Medical Centre Groningen (UMCG in Groningen, The Netherlands. Results: In Mulago Hospital guidelines for blood transfusion practice were not easily available. Medical staff members work on individual professional levels. Students perform poorly due to inconsistency in their supervision. Documentation of blood transfusion in patient files is scarce. There is no immediate bedside observation, so transfusion reactions and obstructions in the blood transfusion flow are not observed. Conclusion: The poor blood transfusion practice is likely to play a role in the morbidity and mortality of patients who receive a blood transfusion. There is a need for a blood transfusion policy and current practical guidelines.

    Full Text Available Background: One of the fatal side effects of transfusion is transfusion reactions. The incidence of transfusion reaction in Sanglah Hospital is still relatively high and far from national target which is 0.01%. To achieve the target of quality, it is necessary to set up an active program so that the number of incidence of transfusion reactions can be decreased. Methods: Pre and posttest interventional study was conducted for 6 months in Sanglah Hospital Bali. All nurses in wards which is blood product frequently used was involved in this study. The intervention in this study was in the form of education and training programs on the application of the closed system and cold chain in the distribution of blood products as well as improved service system. Results: The results showed a decline in the incidence of transfusion reactions occurred every month during the study. The incidence of transfusion reactions occurred each month was 0.77%, 0.56%, 0.5%, 0.49%, 0.45% and 0.38% respectively. The average reduction in the incidence of transfusion reactions was 0.08% every month. The type of transfusion reaction that occurred was 59% urticaria, 29% fever, 7% shortness of breath, 4% fever and chills, and 1% shock. Conclusion: Education and training programs on the application of the cold chain system and closed system in the distribution of blood products as well as the improvement of service system helped reduce the number of the incidence of transfusion reactions in Sanglah Hospital Bali. 

  8. Blood transfusion at the time of the First World War--practice and promise at the birth of transfusion medicine.

    Boulton, F; Roberts, D J

    2014-12-01

    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.

    Blood transfusion is a frequent medical intervention in hospitals. The benefits of, risks of and alternatives to blood transfusions are not consistently understood by patients. The objective of this study was to assess gaps in knowledge and comfort with the current process of consenting patients for blood transfusions. A standardised video regarding the risk and benefits of blood transfusions was developed and feedback regarding this tool was assessed. After informed consent had been obtained, 25 patients receiving their first transfusion at a single academic centre were asked to complete a survey, watch a standardised educational video and complete a follow-up survey. The patient survey revealed that the information recollected from informed consent discussions was variable and incomplete. After the informed consent discussion, the majority of patients were comfortable with having a blood transfusion, although one-third did express concerns or worry about having a blood transfusion. After viewing the video, patients felt that the video improved their understanding of the risks (7·3 of 10), benefits (6·9 of 10) and alternatives (7·1 of 10) to transfusion, but it did not change their comfort with blood transfusion consent. Patients experienced a variable informed consent process prior to blood transfusion. Although the video improved their understanding of risks, it did not improve patient comfort towards giving consent for transfusion as the level of comfort was already high. The video is available online (http://www.youtube.com/watch?v=RxaPnLkgh-0) as an optional resource for patients (and physicians) who wish to receive standardised and accurate information about blood transfusions. © 2014 British Blood Transfusion Society.

    Although there are a number of descriptions of 'blood infusion' in antiquity, it was the publication of the discovery of the circulation of blood in 1628 by William Harvey and the work of Christopher Wren and Robert Boyle in 1663 on the infusion of different materials into dogs that paved the way to the possible practical attempts at actual blood transfusion. Although these early experiments, principally by Richard Lower in England and Jean Denis in France provided valuable information regarding inter-species incompatibility and the problems of blood coagulation, it was not until the work of James Blundell in the early part of the 19th century that blood transfusion was used as a means of blood replacement. However, blood transfusion was not to become an accepted therapeutic possibility until the discovery of practical anticoagulation and the ABO blood groups at the start of the 20th century. © 2012 The Author.

    Plasma is the liquid part of blood. It is estimated 21.6 million liters of plasma collect from Whole blood annually. From these plasma, 4.2 million liters transfuse, 8.1 million liters fractionate, 9.3 million liters waste. Nowadays, blood products and PDM (plasma derived medicine) consider as essential medicine in modern health care and transfusion medicine. Iranian blood transfusion organization as a non-profit organization was established in 1974 in order to centralize all blood transfusion activities from donor recruitment to distribution of blood components to hospitals. Iran is the only country in EMR region with the rate of 20-29.9 blood donations per 1000 population and reached 100% voluntary non-remunerated blood donation in 2007. RBCs and platelets demand are much more than FFPs so the IBTO was faced the surplus plasma that could cause surplus plasma wastage. Simultaneously, hospitals need more plasma derived medicine especially albumin, IVIG, factor VIII, factor IX. IBTO was faced the challenges such as Fractionators selection, Plasma volume shipment, Contract duration, Product profile, Multiple External audits, Cold chain maintenance, Transporting plasma across international borders, NAT test. To overcome plasma wastage and storage of PDM. IBTO involved toll manufacturing in 2005 and not only prevents plasma wastage but also save MOH (ministry of health) budget. Copyright © 2016.

    Transfusion transmissible infections (TTIs) are threats to blood safety. This study investigated TTIs among volunteer blood donors at the Kisumu Regional Blood Transfusion Centre (KRBTC) in Kenya. We performed a retrospective record review of blood donor registers at KRBTC, 2015. Walk-in donors accepted for donation were analyzed to determine prevalence of human immunodeficiency virus (HIV), hepatitis B (HBV), hepatitis C (HCV), and syphilis. Descriptive and associative statistics were calculated using Microsoft Excel and Open-Epi software. The records of a total of 3690 walk-in donors were reviewed, and 2046 were included in the analysis. Mean age was 30 ± 9.6 years, 76% male, 51% married, and 80% were Kisumu residents. Seroprevalence of HIV, HBV, HCV, and syphilis was 2.4%, 3.1%, 2.3%, and 1%, respectively. HBV was the most common TTI among the volunteers. KRBTC should be proactive and address issues of donor self-exclusion, strict adherence to donor selection criteria, and vaccination.

    Full Text Available Backdround: Emerging infectious diseases pose threats to the general human population; including recipients of blood transfusions. Dengue is spreading rapidly to new areas and with increasing frequency of major outbreaks. Screening blood for dengue antigens in dengue-endemic countries would be costly and should, therefore, be recommended only after careful assessment of risk for infection and cost. Aim: A prospective study was conducted to establish the magnitude of the threat that dengue poses to blood safety where it is sporadic with seasonal variations, to quantify risk and to assess that whether screening is feasible and cost-effective. Materials and Methods: Nonstructural protein 1 (NS1 antigen test was done on 1709 donations during dengue outbreak in the months August to November 2013 as an additional test using Bio-Rad Platelia Dengue NS1AG test kit which is one step sandwich format microplate enzyme immunoassay using murine monoclonal antibodies for capture and revelation. Chi-square test was used to find statistical significance. Results and Conclusions: Majority cases were whole blood, replacement, male donors with 76.10% donors in <35 years age group. About 17.85% were single donor platelet donations. NS1 antigen in all donors was negative. In the past, dengue affected mainly children who do not donate blood. With the changing trend, mean age of infection increased affecting the population that does donate blood, further reducing blood donation pool. Further studies need to be done in different geographic regions of the country during dengue transmission season to establish maximum incidence of viremic donations, rates of transfusion transmission and clinical consequences in recipients. If risk is found to be substantial, decision will be taken by the policymakers at what threshold screening should be instituted to ensure safe blood transfusion.

    Perioperative transfusion of red blood cell (RBC) may cause adverse effects. Bloodless-cardiac surgery has been spotlighted to avoid those problems. Off pump coronary artery bypass (OPCAB) surgery can decrease the transfusion. However, the risk factors of transfusions in OPCAB have not been investigated properly. One hundred and thirteen patients (male:female=35:78, mean age=66.7±9.9 years) who received isolated OPCAB were retrospectively analyzed from March 2006 to September 2007. The threshold of RBC transfusion was 28.0% of hematocrit. Bilateral internal thoracic arteries graft were used for 99 patients (87.6%). One hundred and three (91.1%) and 35 patients (31.5%) took aspirin and clopidogrel just before surgery. Sixty-five patients (47.5%) received the RBC transfusion (mean 2.2±3.2 units). Mortality and major complications were not different between transfusion and no-transfusion group. But, ventilator support time, intensive care unit stay and hospitalization period had been reduced in no-transfusion group (ptransfusion were preoperative low hematocrit (75 minutes) and total operation time (>5.5 hours, ptransfusion according to transfusion guideline; over 40% cases could conduct the OPCAB without transfusion. There were no differences in major clinical results between transfusion and non-transfusion group. In addition, when used together with accurate understanding of transfusion risk factors, it is expected to increase the proportion of patients that do not undergo transfusions.

    In recent years, several safety alerts have questioned or restricted the use of some pharmacological alternatives to allogeneic blood transfusion in established indications. In contrast, there seems to be a promotion of other alternatives, based on blood products and/or antifibrinolytic drugs, which lack a solid scientific basis. The Multidisciplinary Autotransfusion Study Group and the Anemia Working Group España convened a multidisciplinary panel of 23 experts belonging to different healthcare areas in a forum for debate to: 1) analyze the different safety alerts referred to certain transfusion alternatives; 2) study the background leading to such alternatives, the evidence supporting them, and their consequences for everyday clinical practice, and 3) issue a weighted statement on the safety of each questioned transfusion alternative, according to its clinical use. The members of the forum maintained telematics contact for the exchange of information and the distribution of tasks, and a joint meeting was held where the conclusions on each of the items examined were presented and discussed. A first version of the document was drafted, and subjected to 4 rounds of review and updating until consensus was reached (unanimously in most cases). We present the final version of the document, approved by all panel members, and hope it will be useful for our colleagues. Copyright © 2015 Elsevier España, S.L.U. and SEMICYUC.

  1. Ambient overnight hold of whole blood prior to the manufacture of blood components.

    Science.gov (United States)

    2010-12-01

    Blood services routinely separate whole blood into components that are then stored under different conditions. The storage conditions used for whole blood prior to separation must therefore be a compromise between the needs of the red cells (which benefit from refrigeration) and plasma and platelets (which are better preserved at ambient temperature). For many years, the approach has been to manufacture plasma and platelet components on the day of blood collection, and to refrigerate any unprocessed blood for manufacture into red cell components on the following day. However, this can make it challenging to maintain adequate stocks of all components. The European practice of 'ambient hold' of whole blood for up to 24 hours prior to processing allows greater flexibility in blood component manufacture, and the data reviewed suggest there is relatively little impact on the quality of red cell or plasma components, and an improvement in the quality of platelet components. © 2010 The Author.

    To avoid unnecessary blood transfusions, physiologic transfusion triggers, rather than exclusively hemoglobin-based transfusion triggers, have been suggested. The objective of this study was to determine systemic and microvascular effects of using a perfluorocarbon-based oxygen carrier (PFCOC) to maintain perfusion and oxygenation during extreme anemia. The hamster (weight, 55-65 g) window chamber model was used. Two isovolemic hemodilution steps were performed using hydroxyethyl starch, 10%, at normoxic conditions to a hematocrit of 19% (hemoglobin, 5.5 g/dl), the point at which the transfusion trigger was reached. Two additional hemodilution exchanges using the PFCOC (Oxycyte) and increasing the fraction of inspired oxygen to 1.0 were performed to reduce the hematocrit to 11% (hemoglobin, 3.8 g/dl) and 6% (hemoglobin, 2.0 g/dl), respectively. No control group was used in the study because this concentration of hemodilution is lethal with conventional plasma expanders. Systemic parameters, microvascular perfusion, functional capillary density, and oxygen tensions across the microvascular network were measured. At 6% hematocrit, the PFCOC maintained mean arterial pressure, cardiac output, systemic oxygen delivery, and oxygen consumption. As hematocrit was decreased from 11% to 6%, functional capillary density, calculated microvascular oxygen delivery, and oxygen consumption decreased; and the oxygen extraction ratio was close to 100%. Peripheral tissue oxygenation was not predicted by systemic oxygenation. The PFCOC, in conjunction with hyperoxia, was able to sustain organ function and partially provide systemic oxygenation during extreme anemia during the observation period. The PFCOC can work as a bridge until erythrocytes are available for transfusion or when additional oxygen is required, despite the possible limitations in peripheral tissue oxygenation.

    The purpose of this study was to determine the impact of a restrictive blood transfusion protocol on the number of transfusions performed and the related effect on patient morbidity. A cohort study was performed using our prospective database with information from January 1, 2000, to June 1, 2013. The restrictive blood transfusion protocol was implemented in September 2011, so this date served as the separation point for the date of operation criteria. For the study, 415 patients undergoing operation for an abdominal malignancy were reviewed. After the restrictive blood transfusion protocol, the percentage of patients who received blood dropped from 35.6% to 28.3%. The percentage of patients who experienced perioperative complication was significantly higher in transfused patients compared with those who did not receive blood (P = .0001). There was no statistical significance observed between the 5 groups for the length of stay at the hospital after their procedure. The restrictive blood transfusion protocol resulted in a reduction of the percentage of patients transfused, and there was no evidence to suggest that it negatively affected the outcomes of patients in this group.

    Of the 99% maternal deaths that take place in developing countries, one-fourth is due to postpartum hemorrhage (PPH). PPH accounts for one-third of all blood transfusions in Bangladesh where the transfusion process is lengthy as most facilities do not have in-house blood bank facilities. In this context, the location where blood is obtained and the processes of obtaining blood products are not standardized, leading to preventable delays in collecting blood, when it is needed. This study evaluated the effectiveness of an online Blood Information Management Application (BIMA) system for reducing lag time in the blood transfusion process. The study was conducted in a public medical college hospital in Dhaka, Bangladesh, and in two proximate, licensed blood banks between January 2014 and March 2015, using a before after design. A total of 310 women (143 before and 177 after), who needed emergency blood transfusion during their perinatal period, as determined by a medical professional, were included in the study. A median linear regression model was employed to assess the adjusted effect of BIMA on transfusion time. After the introduction of BIMA, the median duration between the identified need for blood and blood transfusion reduced from 152 to 122 minutes (P<0.05). For PPH specifically, the reduction was from 175 to 113 minutes (P<0.05). After introducing BIMA and after adjusting for criteria such as maternal age, education, parity, duty roster of providers, and reasons for blood transfusion, a 24 minute reduction in the time was observed between the identified need for blood and transfusion (P<0.001). BIMA was effective in reducing delays in blood transfusion for emergency obstetric patients. This pilot study suggests that implementing BIMA is one mechanism that has the potential to streamline blood transfusion systems in Bangladesh.

    Full Text Available Blood types were determined using SHIGETA (n=136 and DEA1.1 (n=25 kits, in two groups of dogs, consisting of patients that underwent blood transfusions and healthy donors. The tests were conducted in accordance with the procedures established by the manufacturers, using specific monoclonal antibodies kits, heparinized blood for the tube agglutination (TUBE and slide (SLIDE methods, and EDTA treated blood for the CARD and chromatographic (CHROM methods. The clear expression of tube agglutination reaction in the SHIGETA kit provided a good detection of antigens. Positive reactions with anti-DEA1.1 were clear and evident with the CHROM test. SHIGETA tests revealed a predominance 1.1B (47.05% of blood type, common in Rotweilers (81.81% and Romanian Shepherds (73.68% and group 1(-B (24.26%, frequently found in German Shepherds (54.16%, these also representing an important source of compatible blood. DEA1.1 type test, revealed a high frequency of positive dogs (75%, associated with lower number of potential donors. Extrapolation of SHIGETA groups into the DEA system, confirmed the 1(-B positive dogs as DEA 1.1 negative, and their prevalence in German Shepherds also confirmed their known tendency to be “ideal donors”. The CHROME test showed a good efficiency in auto agglutination control and detecting DEA1.1 positive dogs, including patients with severe forms of anemia.

    The adverse effects of blood transfusion after cancer surgery have been recently challenged in older anemic persons or those with substantial intraoperative blood loss. We hypothesized that intraoperative blood transfusions continue to adversely impact short-term cancer surgery outcomes regardless of age or preoperative hematocrit levels. Using the 2005 to 2008 American College of Surgeons National Surgical Quality Improvement Program, we identified 38,926 patients who underwent cancer surgery. Pre-, intra-, and postoperative factors were compared by units of blood transfusion a patient received. Stratified multivariable analyses, by age and hematocrit level, were performed to assess the impact of blood transfusion on operative outcomes, adjusting for covariates. Fourteen percent of patients received an intraoperative blood transfusion. Of those, >60% received only 1 to 2 units of blood. Receipt of intraoperative blood transfusion was associated with higher rates of 30-day operative mortality, major complications, total number of complications, and prolonged length of stay across age groups and in persons with low to normal hematocrit levels. The present study shows that intraoperative blood transfusion adversely impacts short-term operative cancer surgery outcomes across all age groups and in those with low to normal hematocrit levels. These findings provide insightful implications on the patterns of blood transfusion during cancer surgery that deserve further investigation. Published by Mosby, Inc.

  7. Consequences of Transfusing Blood Components in Patients With Trauma: A Conceptual Model.

    Jones, Allison R; Frazier, Susan K

    2017-04-01

    Transfusion of blood components is often required in resuscitation of patients with major trauma. Packed red blood cells and platelets break down and undergo chemical changes during storage (known as the storage lesion) that lead to an inflammatory response once the blood components are transfused to patients. Although some evidence supports a detrimental association between transfusion and a patient's outcome, the mechanisms connecting transfusion of stored components to outcomes remain unclear. The purpose of this review is to provide critical care nurses with a conceptual model to facilitate understanding of the relationship between the storage lesion and patients' outcomes after trauma; outcomes related to trauma, hemorrhage, and blood component transfusion are grouped according to those occurring in the short-term (≤30 days) and the long-term (>30 days). Complete understanding of these clinical implications is critical for practitioners in evaluating and treating patients given transfusions after traumatic injury. ©2017 American Association of Critical-Care Nurses.

    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.

    Background The Community Transfusion Centre in Madrid currently processes whole blood using a conventional procedure (Compomat, Fresenius) followed by automated processing of buffy coats with the OrbiSac system (CaridianBCT). The Atreus 3C system (CaridianBCT) automates the production of red blood cells, plasma and an interim platelet unit from a whole blood unit. Interim platelet unit are pooled to produce a transfusable platelet unit. In this study the Atreus 3C system was evaluated and compared to the routine method with regards to product quality and operational value. Materials and methods Over a 5-week period 810 whole blood units were processed using the Atreus 3C system. The attributes of the automated process were compared to those of the routine method by assessing productivity, space, equipment and staffing requirements. The data obtained were evaluated in order to estimate the impact of implementing the Atreus 3C system in the routine setting of the blood centre. Yield and in vitro quality of the final blood components processed with the two systems were evaluated and compared. Results The Atreus 3C system enabled higher throughput while requiring less space and employee time by decreasing the amount of equipment and processing time per unit of whole blood processed. Whole blood units processed on the Atreus 3C system gave a higher platelet yield, a similar amount of red blood cells and a smaller volume of plasma. Discussion These results support the conclusion that the Atreus 3C system produces blood components meeting quality requirements while providing a high operational efficiency. Implementation of the Atreus 3C system could result in a large organisational improvement. PMID:22044958

    Noncompressible hemorrhage is the leading cause of potentially preventable battlefield death. Combining casualty retrieval from the battlefield and damage control resuscitation (DCR) within the "golden hour" increases survival. However, transfusion requirements may exceed the current blood component stocks held by forward surgical teams. Warm fresh whole blood (WFWB) is an alternative. We report WFWB transfusion training developed by and delivered to a US Golden Hour Offset Surgical Treatment Team and the resulting improvement in confidence with WFWB transfusion. A bespoke instructional package was derived from existing operational clinical guidelines. All Golden Hour Offset Surgical Treatment Team personnel completed initial training, reinforced through ongoing casualty simulations. A record of blood types and donor eligibility was established to facilitate rapid identification of potential WFWB donors. Self-reported confidence in seven aspects of the WFWB transfusion process was assessed before and after training using a five-point Likert scale. Personnel were analyzed by groups consisting of those whose operational role includes WFWB transfusion ("transfusers"), clinical personnel without such responsibilities ("nontransfusers") and nonclinical personnel (other). Comparisons within and between groups were made using appropriate nonparametric tests. Data were collected from 39 (89%) of 44 training participants: 24 (62%) transfusers, 12 (31%) nontransfusing clinicians, and 3 (8%) other personnel. Transfusers and nontransfusers reported increased comfort with all practical elements of WFWB transfusion. The confidence of other personnel also increased, but (likely due to small numbers) was not statistically significant. WFWB transfusion is an integral part of modern deployed military remote DCR. Our in-theater training program rapidly and reproducibly enhanced the comfort in WFWB transfusion in providers from a range of backgrounds and skill-mixes. This model has

    It is important for a hospital to have a well organized blood transfusion service. Our hospital adopted the maximum surgical blood order schedule (MSBOS) and type and screen (T & S) systems in April 1999 and opened a division of transfusion therapy, thus introducing an integrated control system for blood transfusion. In the year (2002), the crossmatch-to-transfusion (C/T) ratio has dropped from 3.94 to 2.01, and the volume of blood transported outside the central operating room and that of waste blood have decreased. The new systems are instrumental in saving preoperatively prepared blood and exercising its qualitative control. From now on, our task is to improve measures to cope with cases of transfusion in excess of MSBOS and reevaluate MSBOS on a regular basis.

    A cross-match to transfused unit ratio of less than 2.0 is frequently used to assess performance in many hospital blood banks. This brief report was initiated to evaluate the practice at a local hospital and to emphasize the importance of regular educational sessions to improve blood transfusion practice. Retrospective data on cross-match : transfused (C : T) ratio of all departments was collected and educational sessions were given to improve practice. Thereafter, a new set of data was collected and change in practice was assessed. Initial data showed total (C : T) ratio of 1.95. After medical staff education, analysis showed clinically significant improvement in blood utilization practice with a (C : T) ratio of 1.60. This brief report indicates the importance of regular physician education, the potential role of blood transfusion committee, and the need to implement clear guidelines for blood transfusion. © 2012 American Association of Blood Banks.

    Red blood cell-derived microparticles are biologically active, submicron vesicles shed by erythrocytes during storage. Recent clinical studies have linked the duration of red blood cell storage with thromboembolic events in critically ill transfusion recipients. In the present study, we hypothesized that microparticles from aged packed red blood cell units promote a hypercoagulable state in a murine model of transfusion. Microparticles were isolated from aged, murine packed red blood cell units via serial centrifugation. Healthy male C57BL/6 mice were transfused with microparticles or an equivalent volume of vehicle, and whole blood was harvested for analysis via rotational thromboelastometry. Serum was harvested from a separate set of mice after microparticles or saline injection, and analyzed for fibrinogen levels. Red blood cell-derived microparticles were analyzed for their ability to convert prothrombin to thrombin. Finally, mice were transfused with either red blood cell microparticles or saline vehicle, and a tail bleeding time assay was performed after an equilibration period of 2, 6, 12, or 24 hours. Mice injected with red blood cell-derived microparticles demonstrated an accelerated clot formation time (109.3 ± 26.9 vs 141.6 ± 28.2 sec) and increased α angle (68.8 ± 5.0 degrees vs 62.8 ± 4.7 degrees) compared with control (each P microparticles exhibited a hundredfold greater conversion of prothrombin substrate to its active thrombin form (66.60 ± 0.03 vs 0.70 ± 0.01 peak OD; Pmicroparticles-injected mice compared with saline vehicle, suggesting thrombin-mediated conversion to insoluble fibrin (14.0 vs 16.5 µg/mL, Pmicroparticles-injected mice as compared with saline vehicle (each Pmicroparticles induce a transient hypercoagulable state through accelerated activation of clotting factors.

    2006-12-01

    In order to investigate the condition and problems of transfusion inspection in Yamanashi Prefecture, a "transfusion operating questionnaire" was carried out. The questionnaire was sent to 30 top hospitals that use many blood components, and we received a reply from 28 hospitals. The blood-transfusion system was unified in 25 hospitals (89.3%). The blood-transfusion therapy commission added 1 hospital with the same function, and it was established in 24 hospitals (85.7%). However, the blood-transfusion therapy commission was only held 6 times or more per year in only 9 hospitals (37.5%). Although doctors responsible for transfusion were appointed in 20 hospitals (71.4%), only 1 hospital appointed full-time doctors. A full-time medical technologist responsible for transfusion was only available in 5 hospitals (17.9%). The activity of the Yamanashi Prefecture joint blood-transfusion therapy commission founded in 2005 is indispensable for the promotion of "safe and proper" blood-transfusion therapy.

  15. Incompatible blood transfusion: Challenging yet lifesaving in the management of acute severe autoimmune hemolytic anemia.

    Autoimmune hemolytic anemia (AIHA) is characterized by the production of autoantibodies directed against red cell antigens. Most patients of AIHA arrive in the emergency or out-patient department (OPD) with severe anemia requiring urgent blood transfusion. Here we share our experience of managing these patients with incompatible blood transfusions and suggest the minimal test required to assure patient safety. A total of 14 patients admitted with severe anemia, diagnosed with AIHA and requiring blood transfusion urgently were included in the study. A series of immunohematological investigations were performed to confirm the diagnosis and issue best match packed red blood cells (PRBC) to these patients. A total of 167 PRBC units were crossmatched for 14 patients of which 46 units (28%) were found to be best match ones and 26 (56.5%) of these units were transfused. A mean turn around time of 222 min was observed in issuing the "best match" blood. Severe hemolysis was observed in all patients with a median hemoglobin increment of 0.88 g/dl after each unit PRBC transfusion. Decision to transfuse in AIHA should be based on the clinical condition of the patient. No critical patient should be denied blood transfusion due to serological incompatibility. Minimum investigations such as direct antiglobulin test (DAT), antibody screening and autocontrol should be performed to ensure transfusion safety in patients. All transfusion services should be capable of issuing "best match" PRBCs in AIHA.

    Blood transfusion has health-related, economical and safety implications. In order to optimise the transfusion chain, comprehensive research data are needed. The Dutch Transfusion Data warehouse (DTD) project aims to establish a data warehouse where data from donors and transfusion recipients are linked. This paper describes the design of the data warehouse, challenges and illustrative applications. Quantitative data on blood donors (eg, age, blood group, antibodies) and products (type of product, processing, storage time) are obtained from the national blood bank. These are linked to data on the transfusion recipients (eg, transfusions administered, patient diagnosis, surgical procedures, laboratory parameters), which are extracted from hospital electronic health records. Expected scientific contributions are illustrated for 4 applications: determine risk factors, predict blood use, benchmark blood use and optimise process efficiency. For each application, examples of research questions are given and analyses planned. The DTD project aims to build a national, continuously updated transfusion data warehouse. These data have a wide range of applications, on the donor/production side, recipient studies on blood usage and benchmarking and donor-recipient studies, which ultimately can contribute to the efficiency and safety of blood transfusion.

    Blood transfusion adversely affects the outcome of coronary artery bypass grafting (CABG), yet blood transfusion after CABG is still common. Total arterial revascularisation (TAR) is increasingly used in current practice but its impact on postoperative blood transfusion is not known. We reviewed the cardiothoracic and blood bank databases and collected data for isolated primary CABG patients from July 2007 to June 2012, excluding patients who had a single graft (n = 148). Perioperative variables of TAR patients (n = 745) were compared with patients who had one or more venous grafts (SVG, n = 1,761) for first-time isolated CABG. The conduits used in TAR patients were predominantly left internal thoracic and radial arteries. Matched group comparison of TAR and SVG patients was performed. The association of TAR with blood transfusion was investigated using multivariate and matched analysis. Of 2,506 patients, the 745 (29.7 %) that had TAR were generally younger, with less complex coronary artery disease and less often diabetic. After correcting for these by 1:1 matching, the mean chest tube drainage and rates of blood transfusion remained significantly lower (p transfused in TAR patients. By multivariate analysis, TAR had an independent effect on reducing blood transfusion after CABG [odds ratio (OR) 0.67, 95 % confidence interval (CI) 0.47-0.97, p = .03]. TAR achieved predominantly with left internal thoracic and radial arteries substantially reduced blood transfusion rates after primary CABG. Further studies are warranted.

    Since the beginning of the 20th century, major technological developments have been made in blood transfusion. Although numerous sociological studies have been conducted on donors, few have highlighted transfused patients, and in this case, the attention has almost exclusively been focused on transfusion risks in patients. Conversely, blood representations associated with the chronically transfused patients have not really been explored in the literature. Based on interviews conducted among chronically transfused patients (patients with hemoglobinopathy, malignant hemopathy or cancer), this present study enables to understand their needs and their expectations through their symbolic representations and their interpretations of blood transfusion, raising tensions as well ethical perspectives.

    Red blood cell (RBC) transfusion is frequently required in pediatric cardiac surgery and is associated with altered outcome and increased costs. Determining which factors predict transfusion in this context will enable clinicians to adopt strategies that will reduce the risk of RBC transfusion. This study aimed to assess predictive factors associated with RBC transfusion in children undergoing low-risk cardiac surgery with cardiopulmonary bypass (CPB). Children undergoing surgery to repair ventricular septal defect or atrioventricular septal defect from 2006 to 2011 were included in this retrospective study. Demography, preoperative laboratory testing, intraoperative data, and RBC transfusion were reviewed. Univariate and multivariate logistic regression analysis were used to define factors that were able to predict RBC transfusion. Then, we employed receiver operating characteristic analysis to design a predictive score. Among the 334 children included, 261 (78%) were transfused. Age (43 mL/kg), type of oxygenator used, minimal temperature reached during CPB (<32°C), and preoperative hematocrit (<34%) were independently associated with RBC transfusion in the studied population. A predictive score 2 or greater was the best predictor of RBC transfusion. The present study identified several factors that were significantly associated with perioperative RBC transfusion. Based on these factors, we designed a predictive score that can be used to develop a patient-based blood management program with the aim of reducing the incidence of RBC transfusion.

    The dramatic impact of hemosiderosis on survival in chronically transfused patients with hereditary anemia is well known. We evaluated whether patients receiving multiple red blood cell (RBC) transfusions are adequately screened for hemosiderosis. We retrospectively assessed hemosiderosis screening and prevalence in adult patients that received over twenty RBC units in the University Medical Centre Utrecht from 2010 till 2015. Hemosiderosis was defined as ferritin ≥1000 μg/L. Adequate screening for chronically transfused patients was defined as any ferritin determined up to 3 months before or any moment after the last transfusion, while for patients that received all transfusions within 3 months (bulk transfusion), ferritin had to be determined after at least twenty transfusions. Of 471 patients, only 38.6% was adequately screened and hemosiderosis prevalence was 46.7%. Hemosiderosis prevalence was 47% in the chronic transfusion group and 12% in the bulk transfusion group. In patients transfused because of hematological malignancy or cardiothoracic surgery, respectively, 74% and 31% were adequately screened and hemosiderosis prevalence was 53% and 13%, respectively. Hemosiderosis screening in our routine practice is suboptimal. Hemosiderosis is not an exclusive complication of multiple transfusions in the hematology ward. We recommend screening for hemosiderosis in all patients receiving multiple transfusions. © 2017 The Authors. European Journal of Haematology Published by John Wiley & Sons Ltd.

    Background HLA antibody testing of previously transfused or pregnant donors may help reduce the risk of transfusion-related acute lung injury (TRALI). However, the prevalence of HLA antibodies in transfused donors has not been well characterized. Methods Transfusion and pregnancy history was obtained from consenting donors. HLA Class I & II antibody testing was performed by multi-antigen bead Luminex platform. Cut off values for class I & II antibodies used normalized background ratio of 10.8 and 6.9 respectively. Linear probability models were used to evaluate potential associations between HLA alloimmunization and donor characteristics. Results 7,920 donors (2,086 males and 5,834 females) were tested. HLA antibody prevalence did not significantly differ between 895 transfused (1.7%) and 1138 non-transfused males (1.0%), [odds ratio (OR) 1.75; 95% CI 0.80, 3.82]. Prevalence in 45 transfused nulliparous females (4.4%, 95% CI 0.1%, 11.8%) was not statistically different from the 1.6% prevalence in 1732 non-transfused nulliparous females (odds ratio 2.94, 95% CI 0.68, 12.74). Transfused parous females had higher prevalence than non-transfused counterparts (p=0.004), odds ratio 1.39 (95% CI 1.07, 1.80). In a linear probability model, the estimated additive risk of transfusion-induced alloimmunization was only 0.8% (95% CI -0.2%, 1.8%), (p=0.10). Donor transfusion history showed that 58% of transfusions occurred >10 years previously. Conclusion Transfused volunteer blood donors do not appear to have a significantly higher prevalence of HLA antibodies than their non-transfused counterparts. Thus, in an effort to reduce TRALI risk, ascertaining past history of transfusion and testing these donors for HLA antibodies is not necessary. PMID:20070615

    Racial disparities in healthcare in the United States are widespread and have been well documented. However, it is unknown whether racial disparities exist in the use of blood transfusion for patients undergoing major surgery. We used the University HealthSystem Consortium database (2009-2011) to examine racial disparities in perioperative red blood cells (RBCs) transfusion in patients undergoing coronary artery bypass surgery (CABG), total hip replacement (THR), and colectomy. We estimated multivariable logistic regressions to examine whether black patients are more likely than white patients to receive perioperative RBC transfusion, and to investigate potential sources of racial disparities. After adjusting for patient-level factors, black patients were more likely to receive RBC transfusions for CABG (AOR = 1.41, 95% CI: [1.13, 1.76], p = 0.002) and THR (AOR = 1.39, 95% CI: [1.20, 1.62], p disparities in blood transfusion persisted after controlling for patient insurance and hospital effects (CABG: AOR = 1.42, 95% CI: [1.30, 1.56], p racial disparities in the use of blood transfusion for CABG and THR (black patients tended to receive more transfusions compared with whites), but not for colectomy. Reporting racial disparities in contemporary transfusion practices may help reduce potentially unnecessary blood transfusions in minority patients.

  7. Is there a "magic" hemoglobin number? Clinical decision support promoting restrictive blood transfusion practices.

    Goodnough, Lawrence Tim; Shah, Neil

    2015-10-01

    Blood transfusion has been identified as one of the most frequently performed therapeutic procedures, with a significant percentage of transfusions identified to be inappropriate. Recent key clinical trials in adults have provided Level 1 evidence to support restrictive red blood cell (RBC) transfusion practices. However, some advocates have attempted to identify a "correct" Hb threshold for RBC transfusion; whereas others assert that management of anemia, including transfusion decisions, must take into account clinical patient variables, rather than simply one diagnostic laboratory test. The heterogeneity of guidelines for blood transfusion by a number of medical societies reflects this controversy. Clinical decision support (CDS) uses a Hb threshold number in a smart Best Practices Alert (BPA) upon physician order, to trigger a concurrent utilization self-review for whether blood transfusion therapy is appropriate. This review summarizes Level 1 evidence in seven key clinical trials in adults that support restrictive transfusion practices, along strategies made possible by CDS that have demonstrated value in improving blood utilization by promoting restrictive transfusion practices. © 2015 Wiley Periodicals, Inc.

    The objective was to identify risk factors associated with blood transfusion in patients undergoing high-order Cesarean delivery (CD). This was a retrospective cohort study of patients undergoing third or more CD by a single maternal-fetal medicine practice between 2005 and 2016. We compared risk factors between women who did and did not receive a red blood cell transfusion during the operation or before discharge. Repeat analysis was performed after excluding women with placenta previa. A total of 514 patients were included, 18 of whom (3.5%; 95% confidence interval [CI], 2.2%-5.5%) received a blood transfusion. Placenta previa was the most significant risk factor for transfusion (61.1% of patients who received a transfusion vs. 1% of patients who did not; p blood transfusion. After women who had placenta previa were excluded, the incidence of blood transfusion was seven of 498 (1.4%; 95% CI, 0.7%-2.9%). Risk factors significantly associated with blood transfusion in the absence of previa were prophylactic anticoagulation during pregnancy and having labored. The incidence of transfusion in patients with no placenta previa, no anticoagulation, and no labor was 0.7% (95% CI, 0.3%-2.1%). Placenta previa was the most predictive risk factor for transfusion with a positive predictive value of 68.8% and a negative predictive value of 98.4%. In patients undergoing a third or more CD, only placenta previa, prophylactic anticoagulation during pregnancy, and having labored are independently associated with requiring a blood transfusion. These data can be used to guide physician ordering of prepared blood products preoperatively. © 2017 AABB.

    Background Blood conservation strategies have been shown to be effective in decreasing red blood cell (RBC) utilization in specific patient groups. However, few data exist describing the extent of RBC transfusion reduction or their impact on transfusion practice and mortality in a diverse inpatient population. Methods We conducted a retrospective cohort study using comprehensive electronic medical record data from 21 medical facilities in Kaiser Permanente Northern California (KPNC). We examined unadjusted and risk-adjusted RBC transfusion and 30-day mortality coincident with implementation of RBC conservation strategies. Findings The inpatient study cohort included 391,958 patients who experienced 685,753 hospitalizations. From 2009 to 2013, the incidence of RBC transfusion decreased from 14.0% to 10.8% of hospitalizations; this change coincided with a decline in pre-transfusion hemoglobin levels from 8.1 to 7.6 g/dL. Decreased RBC utilization affected broad groups of admission diagnoses and was most pronounced in patients with a nadir hemoglobin level between 8 and 9 g/dL (n=73,057; 50.8% to 19.3%). During the study period, the standard deviation of risk adjusted RBC transfusion incidence across hospitals decreased by 44% (p blood conservation strategies, RBC transfusion incidence and pre-transfusion hemoglobin levels decreased broadly across medical and surgical patients. Variation in RBC transfusion incidence across hospitals decreased from 2010 to 2013. Consistent with clinical trial data, more restrictive transfusion practice did not appear to impact 30-day mortality. PMID:25135770

    Borrelia miyamotoi, a recently discovered relapsing fever spirochete, occurs in hard-bodied ticks wherever Lyme disease is endemic. Human infection is associated with relapsing fever and can cause meningoencephalitis in immunocompromised patients. A few cases of transfusion transmission of other relapsing fever spirochete species have been reported but none for B. miyamotoi. Our objective was to determine whether B. miyamotoi transfusion transmission could occur in a murine transfusion model. Herein, we report transfusion transmission of B. miyamotoi through fresh or stored red blood cells (RBCs) in a mouse model. Inbred mice were transfused with B. miyamotoi-infected murine blood that was either freshly collected or stored for 7 days before transfusion. Recipient blood was then longitudinally examined after transfusion by smear and wet mount for evidence of spirochetemia. Motile spirochetes were observed in immunocompromised (SCID) mouse recipients for 28 days after transfusion of both fresh and stored murine B. miyamotoi-infected RBCs. Transient spirochetemia was observed in immunocompetent DBA/2 and C57BL/6 mice, with spirochete clearance occurring within 5 days after transfusion. These data demonstrate that transfusion transmission of B. miyamotoi can occur in mice and suggest that it also may occur in humans. © 2014 AABB.

    Blood transfusion is one of the major areas where serious clinical consequences, even death, related to patient misidentification can occur. In the UK, healthcare professional compliance with pre-transfusion checking procedures which help to prevent misidentification errors is poor. Involving patients at a number of stages in the transfusion pathway could help prevent the occurrence of these incidents. To investigate patients' willingness to be involved and healthcare professionals' willingness to support patient involvement in pre-transfusion checking behaviours. A cross-sectional design was employed assessing willingness to participate in pre-transfusion checking behaviours (patient survey) and willingness to support patient involvement (healthcare professional survey) on a scale of 1-7. One hundred and ten patients who had received a transfusion aged between 18 and 93 (60 male) and 123 healthcare professionals (doctors, nurses and midwives) involved in giving blood transfusions to patients. Mean scores for patients' willingness to participate in safety-relevant transfusion behaviours and healthcare professionals' willingness to support patient involvement ranged from 4.96-6.27 to 4.53-6.66, respectively. Both groups perceived it most acceptable for patients to help prevent errors or omissions relating to their hospital identification wristband. Neither prior experience of receiving a blood transfusion nor professional role of healthcare staff had an effect on attitudes towards patient participation. Overall, both patients and healthcare professionals view patient involvement in transfusion-related behaviours quite favourably and appear in agreement regarding the behaviours patients should adopt an active role in. Further work is needed to determine the effectiveness of this approach to improve transfusion safety. © 2012 The Authors. Transfusion Medicine © 2012 British Blood Transfusion Society.

  12. Improving supply of safe blood and reducing cost of transfusion service through haemovigilance.

    Availability of safe blood remains a major challenge for many developing countries. Unnecessary discontinuation of scarce blood is a major conduit of wastage of scarce blood, as well as man hours and funds. Haemovigilance is a national system of surveillance and alarm, from blood collection to the follow-up of the recipients, gathering and analysing all untoward effects of blood transfusion in order to correct their cause and prevent recurrence. A prospective study to audit discontinuation of blood transfusion at the Obafemi Awolowo University Teaching Hospital Ile-Ife over a period of one and half years was done. Simple febrile non-haemolytic transfusion reaction (FNHTR) was the leading indication for such discontinuation (66.7%). More than half of discontinued transfusion due to FNHTR (58%) was successfully completed on review by trained personnel in transfusion medicine. A system of haemovigilance if incorporated into the blood transfusion service will promote effective monitoring of blood transfusion and reduce wastage of scarce blood/blood products.

    Full Text Available Perioperative fluid, electrolyte and blood transfusion therapy for infants and children can be confusing due the numerous opinions, formulas and clinical applications, which can result in a picture that is not practical and is often misleading. Perioperatively, crystalloids, colloids and blood components are required to meet the ongoing losses and for maintaining cardiovascular stability to sustain adequate tissue perfusion. Recently controversies have been raised regarding historically used formulas and practices of glucose containing hypotonic maintenance crystalloid solutions for perioperative fluid therapy in children. Paediatric intraoperative transfusion therapy, particularly the approach to massive blood transfusion (blood loss ≥ one blood volume can be quite complex because of the unique relationship between the patient′s blood volume and the volume of the individual blood product transfused. A meticulous fluid, electrolyte and blood transfusion management is required in paediatric patients perioperatively because of an extremely limited margin for error. This article reviews the basic concepts in perioperative fluid and blood transfusion therapy for paediatric patients, along with recent recommendations. For this review, Pubmed, Ovid MEDLINE, HINARI and Google scholar were searched without date restrictions. Search terms included the following in various combinations: Perioperative, fluid therapy, paediatrics, blood transfusion, electrolyte disturbances and guidelines.

    Despite legislative acts develloped, many deficiencies were identified in blood requests at the National Blood TransfusionCenter impedding board and blood safety. to evaluate the conformity of the different topics of packed red blood cells requests to the legislation. Our study was prospective descriptive lasting six months (March-August 2011). It assessed all packed red blood cells requests which reached the national blood transfusion center. 16064 packed red blood cells requests from 21 public institutions and 28 private institutions were studied. There was different deficiencies in each item.The absence of birth date in 67.18% of request represented the largest non-compliance within administrative information. A predominance of shortcomings related to transfusion and obstetric history was recorded for clinical information with absence of date of the last transfusion in 91.72% cases, lack of accuracy of any previous transfusion reactions in 88.63% cases and absence of the number of previous pregnancies in 93.15% of transfusion requests prescribed to women. Non-conformities related to the prescribing physician concerned mainly the phone number which was absent in 55.82% of cases. This study revealed a significant lack of awareness of physicians in relation to the law governing transfusion. It is therefore essential to develop training for prescribers to improve transfusion safety.

    Blood transfusion is not without risk. Although the risks of HIV and hepatitis transmission have diminished, haemovigilance programs highlight that other significant transfusion hazards remain. Sepsis from bacterial contamination is the most common residual infectious hazard in developed countries, and events due to clerical error are problematic. Unnecessary transfusions should be avoided. New national guidelines on patient blood management (PBM) emphasise holistic approaches, including strategies to reduce transfusion requirements. Perioperative PBM should incorporate preoperative haemoglobin and medication optimisation, intraoperative blood conservation, and consideration of restrictive postoperative transfusion and cell-salvage techniques. When massive transfusion is required, hospitals should implement massive transfusion protocols. These protocols reduce mortality, improve communication and facilitate adequate provision of blood products. They should include multidisciplinary team involvement and guidelines for use of blood components and adjunctive agents. Although fresh frozen plasma to red blood cell and platelet to red blood cell ratios of ≥ 1 : 2 appear to reduce mortality in trauma patients who receive massive transfusion, there is insufficient evidence to recommend specific ratios. Systematic reviews have found no significant benefit of recombinant activated factor VII in critical bleeding, and an increase in thromboembolic events; specialist haematology advice is therefore recommended when considering use of this agent. The National Safety and Quality Health Service Standards address use of blood and blood products, and provide important transfusion principles for adoption by all clinicians. Storage of red cells in additive solution results in changes, known as the "storage lesion", and studies to determine the clinical effect of the age of blood at transfusion are ongoing.

    The transmission of malaria by blood transfusion was one of the first transfusion-transmitted infections recorded in the world. Transfusion-transmitted malaria may lead to serious problems because infection with Plasmodium falciparum may cause rapidly fatal death. This study aimed to compare real-time polymerase chain reaction (real-time PCR) with rapid diagnostic test (RDT) and light microscopy for the detection of Plasmodium spp. in blood transfusion, both in endemic and non-endemic areas of malaria disease in Iran. Two sets of 50 blood samples were randomly collected. One set was taken from blood samples donated in blood bank of Bandar Abbas, a city located in a malarious-endemic area, and the other set from Tehran, a non-endemic one. Light microscopic examination on both thin and thick smears, RDTs, and real-time PCR were performed on the blood samples and the results were compared. Thin and thick light microscopic examinations of all samples as well as RDT results were negative for Plasmodium spp. Two blood samples from endemic area were positive only with real-time PCR. It seems that real-time PCR as a highly sensitive method can be helpful for the confirmation of malaria infection in different units of blood transfusion organization especially in malaria-endemic areas where the majority of donors may be potentially infected with malaria parasites.

    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

However, certain complications, such as alloimmunization to red blood cells, can create challenges in the management of those patients. Routine phenotyping of blood recipients and the use of phenotype-matched blood units for transfusion have been useful to lower the occurrence of red cell alloantibodies in chronically transfused individuals. Nevertheless, extensive phenotyping is expensive, laborious, and cannot be performed in certain situations. The molecular understanding of blood groups has enabled the design of assays that may be used to better guide matched red blood cell transfusions. This review summarizes key findings related to red cell alloimmunization, the already identified and potential future benefits of blood group genotyping, and how molecular typing is being incorporated in the blood bank's routine to improve clinical and long-term outcomes in chronically transfused patients. Keywords: blood group genotyping, chronically transfused patients, platelet genotyping, RBC alloimmunization

Neurosci. 8 (1996) 319-328] [3] [9] [13] [24]. A spectral fitting method with three components is used for the analysis of intrinsic optical signal [M. Nemoto, Y. Nomura, C. Sato, M. Tamura, K. Houkin, I. Koyanagi, H. Abe, Analysis of optical signals evoked by peripheral nerve stimulation in rat somatosensory cortex: dynamic changes in hemoglobin concentration and oxygenation, J. Cereb. Blood Flow Metab. 19 (1999) 246-259] [17]. In order to validate the analysis, we need the knowledge on contribution of signal resulted from hemoglobin to total intrinsic optical signal. The exchange transfusion with fluorocarbon has the advantage that can change the spectral contribution of hemoglobin [M. Ferrari, M.A. Williams, D.A. Wilson, N.V. Thakor, R.J. Traystman, D.F.

Here we describe a new method of the reduction of hemoglobin signal from somatosensory evoked optical intrinsic signal in rat cortex by the combination of exchange transfusion with fluorocarbon and imaging system of thinned skull cranial window. The method allows for the study of the synaptically evoked changes in light scattering as well as fluorescence of calcium indicator or voltage-sensitive dye without absorption of hemoglobin.

    Blood and apheresis donations are widely considered to be safe with a low incidence of adverse reactions and injuries; however, data reported in the medical literature on the prevalence of adverse events in donors and studies on the predictive risk factors for donor reactions are limited and contradictory. From January 2002 to December 2006 we recorded every adverse reaction verified during 240,596 consecutive blood and apheresis donations (183,855 homologous whole blood donations, 6,669 autologous whole blood donations, 38,647 plasmapheresis, 2,641 plateletpheresis and 8,784 multicomponent donations) at the Italian Transfusion Centres of Verona and Ragusa,. Using a special, pre-arranged form within the quality system, a total of 686 adverse reactions (related to 0.28% of all donations) were recorded. Vasovagal reactions, mostly of mild intensity, were the most commonly observed adverse reactions, with a frequency of 0.20% (487/ 240,596). The frequency of the vasovagal reactions varied according to the different types of donation, being 0.19% (346/183,855) for homologous whole blood donations, 0.24% (16/6,669) for autologous whole blood donations, 0.16% (63/38,647) for plasmapheresis, 0.68% (18/2,641) for plateletpheresis and 0.49 (43/8,784) for multicomponent donations. Citrate toxicity was reported in 0.38% (189/50,072) of apheresis donations. Severe adverse reactions were very rare, as they occurred in 0.004% of the donations (10/240,596). In conclusion, the results of our 5-year survey document that apheresis and blood donation are safe procedures for the donor with a low incidence of adverse reactions; the adverse reactions that did occur were mostly mild and resolved rapidly.

    In 2011, Medicare implemented a prospective payment system (PPS) covering an expanded bundle of services that excluded blood transfusions. This led to concern about inappropriate substitution of transfusions for other anemia management methods. Medicare claims were used to calculate transfusion rates among dialysis patients pre- and post-PPS. Linear probability regressions adjusted transfusion trends for patient characteristics. Dialysis patients for whom Medicare was the primary payer between 2008 and 2012. Pre-PPS (2008-2010) versus post-PPS (2011-2012). Monthly and annual probability of receiving one or more blood transfusions. Monthly rates of one or more transfusions varied from 3.8%-4.8% and tended to be lowest in 2010. Annual rates of transfusion events per patient were -10% higher in relative terms post-PPS, but the absolute magnitude of the increase was modest (-0.05 events/patient). A larger proportion received 4 or more transfusions (3.3% in 2011 and 2012 vs 2.7%-2.8% in prior years). Controlling for patient characteristics, the monthly probability of receiving a transfusion was significantly higher post-PPS (β = 0.0034; P claims, particularly in the inpatient setting. Also, we do not observe which patients might be appropriate candidates for kidney transplantation. Transfusion rates increased post-PPS, but these increases were modest in both absolute and relative terms. The largest increase occurred for patients already receiving several transfusions. Although these findings may reduce concerns regarding the impact of Medicare's PPS on inappropriate transfusions that impair access to kidney transplantation or stress blood bank resources, transfusions should continue to be monitored.

    To investigate the potential additive effects of blood transfusion and sepsis on colon cancer disease-specific survival, cardiovascular disease-specific survival, and overall survival after colon cancer surgery. Perioperative blood transfusions are associated with infectious complications and increased risk of cancer recurrence through systemic inflammatory effects. Furthermore, recent studies have suggested an association among sepsis, subsequent systemic inflammation, and adverse cardiovascular outcomes. However, no study has investigated the association among transfusion, sepsis, and disease-specific survival in postoperative patients. The New York State Cancer Registry and Statewide Planning and Research Cooperative System were queried for stage I to III colon cancer resections from 2004 to 2011. Propensity-adjusted survival analyses assessed the association of perioperative allogeneic blood transfusion, sepsis, and 5-year colon cancer disease-specific survival, cardiovascular disease-specific survival, and overall survival. Among 24,230 patients, 29% received a transfusion and 4% developed sepsis. After risk adjustment, transfusion and sepsis were associated with worse colon cancer disease-specific survival [(+)transfusion: hazard ratio (HR) 1.19, 95% confidence interval (CI) 1.09-1.30; (+)sepsis: HR 1.84, 95% CI 1.44-2.35; (+)transfusion/(+)sepsis: HR 2.27, 95% CI 1.87-2.76], cardiovascular disease-specific survival [(+)transfusion: HR 1.18, 95% CI 1.04-1.33; (+)sepsis: HR 1.63, 95% CI 1.14-2.31; (+)transfusion/(+)sepsis: HR 2.04, 95% CI 1.58-2.63], and overall survival [(+)transfusion: HR 1.21, 95% CI 1.14-1.29; (+)sepsis: HR 1.76, 95% CI 1.48-2.09; (+)transfusion/(+)sepsis: HR 2.36, 95% CI 2.07-2.68] relative to (-)transfusion/(-)sepsis. Additional analyses suggested an additive effect with those who both received a blood transfusion and developed sepsis having even worse survival. Perioperative blood transfusions are associated with shorter survival

    Caesarean delivery carries a risk of major intra-operative blood loss and its performance is often delayed by non-availability of blood and blood products. Unnecessary cross-matching and reservation of blood lead to apparent scarcity in centres with limited supply. This study set out to identify the risk factors for blood transfusion in women who underwent caesarean delivery at a tertiary obstetric unit with a view to ensuring efficient blood utilization. A prospective cohort analysis of 906 women who had caesarean deliveries at the Lagos State University Teaching Hospital, Nigeria between January and December, 2011. A comparison was made between 188 women who underwent blood transfusion and 718 who did not. Data were obtained on a daily basis by investigators from patients, clinical notes and referral letters using structured pre-tested data collecting form. Socio-demographic characteristics; antenatal, perioperative and intraoperative details; blood loss; transfusion; and puerperal observations were recorded. EPI-Info statistical software version 3.5.3 was used for multivariable analysis to determine independent risk factors for blood transfusion. Of the 2134 deliveries during the study period, 906 (42.5%) had caesarean deliveries and of which 188 (20.8%) were transfused. The modal unit of blood transfused was 3 pints (41.3%). The most common indication for caesarean section was cephalo-pelvic disproportion (25.7%).The independent risk factors for blood transfusion at caesarean section were second stage Caesarean Section (aOR = 76.14, 95% CI = 1.25-4622.06, p = 0.04), placenta previa (aOR = 32.57, 95% CI = 2.22-476.26, p = 0.01), placental abruption (aOR = 25.35, 95% CI = 3.06-211.02, p blood transfusion (aOR = 0.24, 95% CI = 0.09-0.61, p = 0.0024). The overall risk of blood transfusion in cesarean delivery is high. Paturients with the second stage Caesarean section, placenta previa, abruptio placentae and

    Experimental data have shown that the transfusion of older red blood cell units causes alloimmunization, but the clinical applicability of this statement has never been properly assessed in non-sickle cell patients. It has been hypothesized that older units have higher numbers of cytokines, increasing the risk of alloimmunization related to antigen-presenting events. The goal of this study was to evaluate the association between the transfusion of older red blood cell units subjected to bedside leukodepletion and alloimmunization. All patients submitted to transfusions of bedside leukodepletion red blood cell units proven to have become alloimmunized in one oncologic service between 2009 and 2013 were enrolled in this study. A control group was formed by matching patients without alloimmunization in terms of number of transfusions and medical specialty. The median age of transfused units, the percentage of transfused red blood cell units >14 days of storage in relation to fresher red cell units (≤14 days of storage) and the mean age of transfused units older than 14 days were compared between the groups. Alloimmunized and control groups were homogeneous regarding the most relevant clinical variables (age, gender, type of oncological disease) and inflammatory background (C-reactive protein and Karnofsky scale). The median age of transfused red blood cell units, the ratio of older units transfused compared to fresher units and the mean age of transfused units older than 14 days did not differ between alloimmunized and control patients (17 vs. 17; 68/32 vs. 63.2/36.8 and 21.8±7.0 vs. 21.04±7.9; respectively). The transfusion of older red blood cell units subjected to bedside leukodepletion is not a key risk factor for alloimmunization. Strategies of providing fresh red cell units aiming to avoid alloimmunization are thus not justified. Copyright © 2015 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

    To study the prevalence of HBsAg, Anti-HCV, HIV, Syphilis and Malaria in blood donors. This is a cross sectional descriptive study, conducted at Blood bank and Transfusion center at Liaquat University of Medical & Health Sciences (LUMHS) Hyderabad, during the period from January, 2014 to June, 2015. A total of 4683 blood donors were screened for HBsAg, Anti-HCV and HIV on Architect 20001 (manufactured by Abbott), employing chemiluminescent microparticle immunoassay (CMIA). For Syphilis, VDRL ICT kits were used and Malaria parasite was screen through MP slides. Blood grouping was performed by both forward and reverse methods. This study showed a high frequency of HBsAg, VDRL and malaria positivity among the O-ve blood group donors, i.e. 3.70%, 9.25% and 0.61% respectively. Blood group B-ve individuals were commonly infected with HCV (12.5%) as compared with all other blood group donors. HIV is more commonly reported in A+ve blood group individuals. Blood group O+ve is more prevalent (37.41 %). High frequency of HCV infection in blood donors advocates implementation of strict screening policy for donors and public awareness campaigns about preventive measures to reduce the spread of this infection as well as other transfusion transmissible infections.

    Transfusion with red blood cells (RBCs) is associated with adverse clinical outcomes. We determined whether an intraoperative RBC transfusion is related to postoperative complications in patients undergoing open radical cystectomy. We also compared the effect of transfusion with fresh versus old blood on postoperative complications. A total of 261 patients undergoing open radical cystectomy were divided into no-transfusion or transfusion groups. Transfused patients were divided according to RBC storage duration (fresh, ≤ 14 days; old, > 14 days). Postoperative complications, such as infection, paralytic ileus, urinary tract obstruction, and anastomotic leak, were noted. Infection (26.5%) was the most common postoperative complication, followed by procedural (17.6%), gastrointestinal (16.7%), renal (13.7%), and vascular (10.5%) problems. Age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.00-1.07; P = .029), urinary diversion with a neobladder (OR, 2.30; 95% CI, 1.29-4.11; P = .005), and intraoperative RBC transfusion (OR, 1.77; 95% CI, 1.02-3.07; P = .042) were independent predictors of postoperative complications in a binary logistic analysis. Patients (n = 172; old blood, n = 47; fresh blood, n = 116; mixed blood, n = 9) who received an intraoperative RBC transfusion had a higher incidence of postoperative complications than those (n = 89) who did not undergo intraoperative transfusion (65.1% vs. 49.4%, P transfusions with old blood and fresh blood was observed (63.8% vs. 65.5%). Intraoperative RBC transfusion is associated with increased postoperative complications in patients undergoing open radical cystectomy. The RBC storage duration may not affect the incidence of postoperative complications in this study population. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Background/Objectives. Blood transfusion is a critical issue for patients with chronic diseases such as heart failure, chronic kidney disease, and malignancy. However, side effects are not rare. The purpose of the study is to evaluate the frequency of adverse blood transfusion reactions in hospitalized elderly patients during a one-year period. Design/Setting/Participants. Blood transfusion reactions such as fever, chills, dyspnea, and others following blood transfusions in hospitalized geriatric patients during one-year period were examined. Results. 382 blood units (242 patients were administered during the study period. In 40 (11% cases, blood transfusion reactions occurred. Fever was the most common reaction in 29 cases (72%, four (10% had shortness of breath, and 3 (8% had vomiting and chills each. There were no lethal cases in the 24-hour period following blood transfusions. Conclusion. A relatively low rate of adverse blood transfusion reactions occurred in our geriatric patients. We may speculate that this is related to underreporting of minor symptoms due to the high percentage of demented patients in this population.

    Full Text Available Abstract Background In the Confidential Enquiry into Maternal Deaths (CEMD Report, the very high risk of mortality in women who refuse blood transfusions is highlighted. The objectives were to establish current knowledge about, and views of transfusion in our pregnant population and to establish the level of compliance with the set audit standard. Method Questionnaire survey of 228 women, including both high and low risk pregnancies, attending ante-natal clinic between 2–9 May 2000 at the North Staffordshire Maternity Hospital, Stoke on Trent. Results The response rate was 100%. Only 43% were aware of the possible need for blood transfusion in pregnancy. If a blood transfusion was required, 92% stated that they would accept a blood transfusion in pregnancy. Four percent stated that they would not accept a transfusion because of religious reasons and risk of infection and the remaining four percent did not declare a reason. Conclusions This short survey identified that 57% of women were not aware of the possible need for blood transfusion during pregnancy. There is a need for more information to be shared on this subject with all antenatal women. Women who would refuse a transfusion need to be identified at booking and be referred for counselling and a management plan made for pregnancy, labour and delivery.

    Severe anemia in children is a major public health problem in sub-Saharan Africa. In this study we describe clinical and operational aspects of blood transfusion in children admitted to Coast Provincial General Hospital, Kenya. This was an observational study where over a 2-year period, demographic and laboratory data were collected on all children for whom the hospital blood bank received a transfusion request. Clinical data were obtained by retrospective review of case notes over the first year. There were 2789 requests for blood for children (median age, 1.8 years; interquartile range [IQR], 0.6-6.6 years); 70% (1950) of the samples were crossmatched with 85% (1663/1950) issued. Ninety percent (1505/1663) were presumed transfused. Median time from laboratory receipt of request to collection of blood was 3.6 hours (IQR, 1.4-12.8 hr). Case notes of 590 children were reviewed and median pretransfusion hemoglobin level was 6.0 g/dL (IQR, 4.2-9.1 g/dL). Ninety-four percent (186) were transfused "appropriately" while 52% (120) were transfused "inappropriately." There was significant disagreement between the clinical and laboratory diagnosis of severe anemia (exact McNemar's test; p blood transfusions but only 41% (106) of these had a positive blood film. In this setting, clinicians often order blood based on the clinical impression of "severe anemia." This has implications for laboratory workload and the blood supply itself. However, the majority of children with severe anemia were appropriately transfused. The use of antimalarials with blood transfusions irrespective of blood film results is common practice. © 2016 The Authors. Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

    To examine outcomes in patients who receive small amounts of intraoperative blood transfusion. Longitudinal, uncontrolled observational study evaluating results of intraoperative transfusion in patients entered into the American College of Surgeons National Surgical Quality Improvement Program database. We made propensity-matched comparisons between patients who received and did not receive intraoperative transfusion to minimize confounding when estimating the effect of intraoperative transfusion on postoperative outcomes. We queried the American College of Surgeons National Surgical Quality Improvement Program database for patients undergoing operations between January 1, 2005, and December 31, 2009. A large sample of surgical patients from 173 hospitals throughout the United States. Operative mortality and serious perioperative morbidity (≥1 of 20 complications). After exclusions, 941,496 operations were analyzed in patients from 173 hospitals. Most patients (893,205 patients [94.9%]) did not receive intraoperative transfusions. Patients who received intraoperative infusion of 1 unit of packed red blood cells (15,186 patients [1.6%]) had higher unadjusted rates of mortality and more serious morbidity. These rates further increased with intraoperative transfusion of more than 1 unit of packed red blood cells in a dose-dependent manner. After propensity matching to adjust for multiple preoperative risks, transfusion of a single unit of packed red blood cells increased the multivariate risk of mortality, wound problems, pulmonary complications, postoperative renal dysfunction, systemic sepsis, composite morbidity, and postoperative length of stay compared with propensity-matched patients who did not receive intraoperative transfusion. There is a dose-dependent adverse effect of intraoperative blood transfusion. It is likely that a small, possibly discretionary amount of intraoperative transfusion leads to increased mortality, morbidity, and resource use

    Full Text Available Background/Aim. In spite of the evidence suggesting a significant morbidity associated with blood transfusions, the use of blood and blood products remain high in cardiac surgery. To successfully minimize the need for blood transfusion, a systematic approach is needed. The aim of this study was to investigate the influence of different anesthetic techniques, general vs combine epidural and general anesthesia, as well as different surgery strategies, on-pump vs off-pump, on postoperative bleeding complications and the need for blood transfusions during perioperative period. Methods. Eighty-two consecutive patients scheduled for coronary artery bypass surgery were randomized according to surgical and anesthetic techniques into 4 different groups: group 1 (patients operated on off-pump, under general anesthesia; group 2 (patients operated on off-pump, with combined general and high thoracic epidural anesthesia; group 3 (patients operated on using standard revascularization technique, with the use of extracorporeal circulation, under general anesthesia, and group 4 (patients operated on using standard revascularization technique, with the use of extracorporeal circulation, with combined general and high thoracic epidural anesthesia. Indications for transfusion were based on clinical judgment, but a restrictive policy was encouraged. Bleeding was considered significant if it required transfusion of blood or blood products, or reopening of the chest. The quantity of transfused blood or blood products was specifically noted. Results. None of the patients was transfused blood or blood products during the surgery, and as many as 70/81 (86.4% patients were not transfused at all during hospital stay. No difference in postoperative bleeding or blood transfusion was noted in relation to the type of surgery and anesthetic technique applied. If red blood cells were transfused, postoperative bleeding was the most influential parameter for making clinical

    Full Text Available OBJECTIVE: This study aimed to compare the storage properties of red blood cell (RBC concentrates of umbilical cord blood (UCB and adult donor blood (ADB, and to evaluate the feasibility of UCB-RBC concentrate as an autologous source for blood transfusion in very low birth weight (VLBW preterm neonates. METHODS: In all, 30 newborn (10 preterm, 20 full term UCB and 31 ADB units were collected. RBC concentrates were stored and compared with regard to pH, potassium (K+, 2,3-biphosphoglycerate (2-3-BPG, adenosine tri-phosphate (ATP, plasma Hb, and bacterial contamination on d 1, 21, and 35 of storage. RESULTS: The K+ level increased with time and differed significantly between storage d 1 and 21, and between storage d 1 and 35 in both the UCB and ADB units. Initial and d 21 K+ levels were higher in the UCB units than in the ADB units. The 2,3-BPG level did not differ significantly between the UCB-PRC and ADB-PRC samples. After 35 d of storage both UCB-PRC and ADB-PRC samples exhibited significant differences from the initial free Hb, intracellular ATP, and pH values. Significant differences in intracellular ATP and pH were also observed between the UCB-PRC and ADB-PRC samples. CONCLUSION: The volume of harvested and prepared UCB-PRC can be used for some of the blood transfusions required during the neonatal period and thus may decrease the number of allogeneic transfusions, especially in preterm newborns. The hematological and biochemical changes that occurred in UCB during storage were comparable with those observed in ADB, and do not pose a risk to the immature metabolism of neonates. UCB-RPC prepared and stored under standard conditions can be a safe alternative RBC source for transfusions in VLBW newborns.

    Increasing awareness of the risks of blood transfusion has prompted examination of red cell transfusion practice in obstetrics. A six-month prospective observational study was performed to examine blood transfusion practices in patients undergoing caesarean delivery at three hospitals in Pakistan. In the three hospitals (two private, one public) 3438 caesarean deliveries were performed in the study period. Data were collected on patient demographics, indications for transfusion, ordering physicians, consent, associations with obstetric factors, estimated allowable blood loss, calculated blood loss, pre- and post-transfusion haemoglobin and discharge haemoglobin. A total number of 397 (11.5%) patients who underwent caesarean section received a blood transfusion. The highest transfusion rate of 16% was recorded in the public tertiary care hospital compared to 5% in the two private hospitals. Emergency caesarean delivery and multiparity were associated with blood transfusion (Ptransfusion in 98% of cases. In 343 (86%) patients, blood transfusion was given even when the haemoglobin was >7g/dL. The method for documenting the indication or consent for transfusion was not found in any of the three hospitals. Blood transfusion was prescribed more readily in the public hospital. Identification of a transfusion trigger and the development of institutional guidelines to reduce unnecessary transfusion are required. Copyright © 2014 Elsevier Ltd. All rights reserved.

    To determine whether brief, face-to-face educational outreach visits can improve the appropriateness of blood product utilization. Randomized, controlled multicenter trial with 6-month follow-up. Surgical and medical services of two pairs of matched community and teaching hospitals in Massachusetts. One hundred one transfusing staff surgeons and attending medical physicians. A professionally based transfusion specialist presented one surgical- or medical-service-wide lecture emphasizing appropriate indications, risks, and benefits of red blood cell transfusions; brief, graphic, printed educational guidelines; and one 30-minute visit with each transfusing physician. No data feedback was provided. Educational messages emphasized the lack of utility of the traditional threshold for red blood cell transfusions (hematocrit, 30%) and transfusion risks (eg, viral hepatitis). Proportion of red blood cell transfusions classified as compliant or noncompliant with blood transfusion guidelines, or indeterminate 6 months before and 6 months after an experimental educational intervention. Based on analyses of 1449 medical record audits of red blood cell transfusions that occurred 6 months before and 6 months after the educational intervention, the average proportion of transfusions not in compliance with criteria declined from 0.40 to 0.24 among study surgeons (-40%) compared with an increase from 0.40 to 0.44 (+9%) among control surgeons (P = .006). These effects were consistent across procedure type and specialty. On average, study surgeons in the postintervention period performed transfusions when hematocrits were 2.0 percentage points lower than before the intervention (28.3% preintervention vs 26.3% postintervention), and lower than in the control group (28.3% preintervention and postintervention; P = .04). Likely savings in blood use for surgical services probably exceeded program costs, even without considering reduced risks of infection. No effects were observed among

    Full Text Available Background. The risk of severe adverse events to blood transfusion is very low. More frequent are adverse events to transfusion, which are not severe, but must also be treated. Introduction of the haemovigilance system is a way of detecting and analysing them in order to correct their cause and to prevent their recurrence.Methods. In 2002 we collected data on transfusion adverse events registered by the Blood Transfusion Centre of Slovenia and blood transfusion departments in Slovene general hospitals.Results. 86 adverse events to transfusion were reported in 2002. The most frequent were non-haemolytic fever (42 cases and allergic reactions (27 cases. 5 cases of haemolysis and 1 of pulmonary oedema were also reported. 11 cases were not categorised.Conclusions. We suppose that the collected data is not complete. However, it does give us insight into the clinical part of the transfusion chain. The most frequently registered adverse events in Slovenia are the same as in other countries. The presented data is the beginning of a systematic registration, using standard forms and reporting. Analysis and a followup activities are the basis for improvement of the blood transfusion safety and quality of treatment.

    Whole blood donation is generally considered to be a safe procedure, but occasionally adverse reactions of varying severity may occur during or at the end of the collection. The aim of the study was to estimate the frequency and type of adverse events occurring during blood donation and to assess the practices which would help to minimise them. This retrospective single-centre study was conducted from June 2007 to November 2009 at a regional blood transfusion centre. All whole blood donations made at the centre were analysed. All adverse events occurring during or at the end of donation were noted using a standardised format. Overall 113 adverse events were reported in relation to 19,045 donations, resulting in an overall adverse event rate of 0.6%, that is, an incidence of 1 in every 166 donations. Presyncopal symptoms, in other words vasovagal reactions of mild intensity, were the most commonly observed adverse reactions and accounted for approximately 70% of all adverse reactions noted. Only 0.6% of blood donations were complicated by adverse events and most of these events were presyncopal symptoms. Our study reinforces the fact that blood donation is a very safe procedure which could be made even more event-free by following certain friendly, reassuring and tactful practices.

Although blood transfusions are much more frequent and have many connotations, derived from religious values, mass culture, or personal ideas, there is no study of the perception the patients have of changes in their behavior and values after a transfusion. This study’s objective was to assess perceived changes in behavior and values after a red blood cell transfusion.Materials and methods: Exploratory study through semistructured interviews with seven adults transfused after orthopedic surgery.Results: Blood had strong symbolic values for all subjects. Each of the seven participants mentioned positive characteristics that they would like to receive from the donor. Six subjects out of the seven acknowledged the possibility that transfusions might induce changes in behavior or values. Three subjects clearly stated that they would refuse to receive blood from a criminal for fear that some negative characteristic may be transmitted to them. Furthermore, three subjects acknowledged that their transfusion might have changed their own behavior or values.Discussion: This study shows that patients might feel that transfusions could modify their behavior or values and that certain personality traits of the donor could be transmitted. Further research in a larger population is warranted to evaluate the incidence of a perceived changed in behavior or values after a blood transfusion, which would then lead to changes in the way information is provided to

    Treating the precipitating factors of delirium is the mainstay of the prevention and treatment of delirium. We aim to investigate the role of anemia and blood transfusion within the multicomponent prevention and treatment strategy of delirium. Systematic review. We included cohort studies or Randomized Controlled Trials (RCTs) that considered blood transfusion as treatment for delirium or risk factor, and had delirium as outcome. Hospitalized patients above 55 years old. We searched MEDLINE from 1946 through November 2014. Quality assessment and data extraction were performed systematically. We included 23 studies (n = 29,471). The majority of the studies (n = 22) had a limited quality and for one study quality was uncertain. Two studies evaluated the association between transfusion strategy and postoperative delirium and found no association. Twenty-one studies investigated blood transfusion as a risk factor for delirium. In four of the 21 studies it could be assumed that delirium occurred after transfusion. One of these studies stated that transfusion was a significant risk factor for subsequent delirium (odds ratio (OR) = 3.68, 95% confidence interval (CI) = 1.32-10.94). The other three studies found no association between transfusion and delirium. In the remaining 17 studies, it was not clear whether delirium occurred before or after transfusion, so no conclusion could be drawn on the role of transfusion in delirium development. The majority of the included studies was not suited to answer the research question properly as the time course of the beginning of delirium as to transfusion was lacking. Our review shows that there is no good quality evidence available for blood transfusion to be a risk factor for delirium or to be a preventive or treatment option. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    This study was conducted in Bamenda, Cameroon. The objectives of the study were to develop a theoretical framework to better understand local attitudes towards blood donation and transfusion, to identify factors that motivate and deter blood donation and to identify interventions to improve the supply of blood for transfusion at Bamenda Regional Hospital. The supply of blood for transfusion in sub-Saharan Africa is insufficient. Cameroon has no national blood service and the collection and screening of blood is the responsibility of individual hospitals. At Bamenda Regional Hospital patient relatives recruit replacement blood donors, who may or may not be family members, and shortages of blood and delays in transfusion are frequent. Qualitative research methods were used: direct observation, in-depth interviews, focus group discussions and a simulation exercise. Participants were clinical and laboratory staff, patient relatives, blood donors, secondary school students and community members. Attitudes towards blood donation and transfusion fit a transanctionalist framework of health decision making. Deterrents to blood donation are multiple and varied. Some form of compensation is often expected, even by family members, although the blood donation is still considered 'voluntary' by the donor. This study confirms that interventions to improve the blood supply must take into account local attitudes and conditions. In Bamenda, a variety of pragmatic approaches are required including education around specific biological misperceptions identified in the study and the retention of replacement donors as repeat donors. Issues around compensation for blood donation require further work. © 2011 The Authors. Transfusion Medicine © 2011 British Blood Transfusion Society.

    Blood transfusion is linked to a negative outcome for malignant tumors. The aim of this study was to evaluate aggressive surgical resection for hilar cholangiocarcinoma (HCCA) and assess the impact of perioperative blood transfusion on long-term survival. Sixty-six consecutive major hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for HCCA were performed using macroscopically curative resection at our institute from 2002 to 2012. Clinicopathologic factors for recurrence and survival were retrospectively assessed. Overall survival rates at 1, 3, and 5 years were 86.7, 47.3, and 35.7 %, respectively. In univariate analysis, perioperative blood transfusion and a histological positive margin were two of several variables found to be significant prognostic factors for recurrence or survival (Pblood transfusion was independently associated with recurrence (hazard ratio (HR)=2.839 (95 % confidence interval (CI), 1.370-5.884), P=0.005), while perioperative blood transfusion (HR=3.383 (95 % CI, 1.499-7.637), P=0.003) and R1 resection (HR=3.125 (95 % CI, 1.025-9.530), P=0.045) were independent risk factors for poor survival. Perioperative blood transfusion is a strong predictor of poor survival after radical hepatectomy for HCCA. We suggest that circumvention of perioperative blood transfusion can play an important role in long-term survival for patients with HCCA.

    Hepatitis B and hepatitis C are significant health problems that might involve the late sequel of liver cirrhosis and hepatocellular carcinoma. A high prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in blood donors poses an increased risk of window period transmission through blood transfusion. The present study aimed to know the seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) among blood donors in regional blood transfusion services of Nepal. This was a retrospective study conducted among blood donors in Banke (5,211), Morang (5,351), and Kaski (5,995) blood transfusion services. Serum samples were tested for hepatitis B surface antigen (HBsAg) and anti-HCV antibodies using rapid enzyme immunoassays. The donors information was collected via the donor record register through their respective blood transfusion services. The software "Winpepi ver 3.8" was used for statistical analysis. The seroprevalence rate of HBV was highest in the Banke (1.2%) followed by Biratnagar (0.87%) and Kaski (0.35%) (P 0.05). The seroprevalence of HBV was significantly higher than HCV in all three blood transfusion services. The burden of HBV as well as HCV seems to be higher in male donors (P > 0.05). The study revealed that the seroprevalence of HBV was alarmingly higher in two of the three blood transfusion services. Implementation of community-based preventive measures and improved strategies for safe blood supply might prove useful to decrease the seroprevalence.

    Full Text Available Iron chelation therapy is often used to treat iron overload in patients requiring transfusion of red blood cells (RBC. A 76-year-old man with MDS type refractory cytopenia with multilineage dysplasia, intermediate-1 IPSS risk, was referred when he became transfusion dependent. He declined infusional chelation but subsequently accepted oral therapy. Following the initiation of chelation, RBC transfusion requirement ceased and he remained transfusion independent over 40 months later. Over the same time course, ferritin levels decreased but did not normalize. There have been eighteen other MDS patients reported showing improvement in hemoglobin level with iron chelation; nine became transfusion independent, nine had decreased transfusion requirements, and some showed improved trilineage myelopoiesis. The clinical features of these patients are summarized and possible mechanisms for such an effect of iron chelation on cytopenias are discussed.

    Allogeneic blood transfusion (ABT) is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD), especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient), febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion-related immuno-modulation, and transmission of almost all infectious diseases (bacteria, virus, protozoa and prion), which might result in increased risk of morbidity and mortality. Unfortunately, the main physiological goal of ABT, i.e. to increase oxygen consumption by the hypoxic tissues, has not been well documented. In contrast, the ABT is usually misused only to increase the haemoglobin level within a fixed protocol [mostly two by two packed red blood cell (PRC) units] independently of the patient’s tolerance to normovolemic anaemia or his clinical response to the transfusion of PRC units according to a “one-by-one” administration schedule. Evidence-based clinical guidelines may promote best transfusion practices by implementing restrictive transfusion protocols, thus reducing variability and minimizing the avoidable risks of transfusion, and the use of autologous blood and pharmacologic alternatives. In this regard, preoperative autologous blood donation (PABD) consistently diminished the frequency of ABT, although its contribution to ABT avoidance is reduced when performed under a transfusion protocol. In addition, interpretation of utility of PABD in surgical IBD patients is hampered by scarcity of published data. However, the role of autologous red blood cells as drug carriers is promising. Finally, it must be stressed that a combination of methods used within well-constructed protocols will offer better

    Critically ill patients frequently receive plasma transfusion under the assumptions that abnormal coagulation test results confer increased risk of bleeding and that plasma transfusion will decrease this risk. However, the effect of prophylactic plasma transfusion remains poorly understood. The objective of this study was to determine the relationship between prophylactic plasma transfusion and bleeding complications in critically ill patients. This is a retrospective cohort study of adults admitted to the intensive care unit (ICU) at a single academic institution between January 1, 2009 and December 31, 2013. Inclusion criteria included age ≥18 years and an international normalized ratio measured during ICU admission. Multivariable propensity-matched analyses were used to evaluate associations between prophylactic plasma transfusion and outcomes of interest with a primary outcome of red blood cell transfusion in the ensuing 24 hours and secondary outcomes of hospital- and ICU-free days and mortality within 30 days of ICU discharge. A total of 27,561 patients were included in the investigation with 2472 (9.0%) receiving plasma therapy and 1105 (44.7%) for which plasma transfusion was prophylactic in nature. In multivariable propensity-matched analyses, patients receiving plasma had higher rates of red blood cell transfusion (odds ratio: 4.3 [95% confidence interval: 3.3-5.7], P plasma in the critically ill was not associated with improved clinical outcomes. Further investigation examining the utility of plasma transfusion in this population is warranted.

    To evaluate whether blood transfusion exerts an adverse influence on cancer evolution, a prospective clinical and immunologic investigation was carried out on 58 surgical patients with gastric or colorectal adenocarcinoma. None had had previous transfusion; 35 received perioperative transfusion. Among preoperative variables, only red cell count and hemoglobin concentration were significantly reduced in the patients transfused at operation. Other clinical characteristics and immunologic functions (except interferon-gamma release) did not differ significantly from those of untransfused patients. The survival rate of transfused patients, although shorter, was not significantly different from that of untransfused patients. Immunologic tests done after surgery on 30 patients (17 transfused and 13 untransfused) did not show significant differences in the two groups. Significant increases in interleukin-2-stimulated production and immunoglobulin M synthesis were observed in transfused patients after surgery. Patients transfused perioperatively with more than 3 units of blood had some evidence of decreased immune function, but differences were not significant. While shorter survival and some immunologic changes may correlate with the number of transfusions, more patients must be studied to determine whether this relationship will be confirmed.

    In an environment of limited health care resources, it is crucial for health care systems which provide blood transfusion to have accurate and comprehensive information on the costs of transfusion, incorporating not only the costs of blood products, but also their administration. Unfortunately, in many countries accurate costs for administering blood are not available. Our study aimed to generate comprehensive estimates of the costs of administering transfusions for the UK National Health Service. A detailed microcosting study was used to cost two key inputs into transfusion: transfusion laboratory and nursing inputs. For each input, data collection forms were developed to capture staff time, equipment, and consumables associated with each step in the transfusion process. Costing results were combined with costs of blood product wastage to calculate the cost per unit transfused, separately for different blood products. Data were collected in 2014/15 British pounds and converted to US dollars. A total of 438 data collection forms were completed by 74 staff. The cost of administering blood was $71 (£49) per unit for red blood cells, $84 (£58) for platelets, $55 (£38) for fresh-frozen plasma, and $72 (£49) for cryoprecipitate. Blood administration costs add substantially to the costs of the blood products themselves. These are frequently incurred costs; applying estimates to the blood components supplied to UK hospitals in 2015, the annual cost of blood administration, excluding blood products, exceeds $175 (£120) million. These results provide more accurate estimates of the total costs of transfusion than those previously available. © 2018 AABB.

    Among transfused patients, the effect of the duration of red blood cell storage on mortality remains unclear. This study aims to compare the mortality of patients who were transfused with fresher versus older red blood cells. We performed an updated systematic search in the CENTRAL, MEDLINE, EMBASE and CINAHL databases, from January 2015 to October 2016. RCTs of hospitalized patients of any age comparing transfusion of fresher versus older red blood cells were eligible. We used a random-effects model to calculate pooled risk ratios (RRs) with corresponding 95% confidence interval (CI). We identified 14 randomized trials that enrolled 26 374 participants. All-cause mortality occurred in 1219 of 9531 (12·8%) patients who received a transfusion of fresher red blood cells and 1810 of 16 843 (10·7%) in those who received older red blood cells (RR: 1·04, 95% CI: 0·98-1·12, P = 0·90, I2 = 0%, high certainty for ruling out benefit of fresh blood, moderate certainty for ruling out harm of fresh blood). In six studies, in-hospital death occurred in 691 of 7479 (9·2%) patients receiving fresher red cells and 1291 of 14 757 (8·8%) receiving older red cells (RR: 1·06, 95% CI: 0·97-1·15, P = 0·81, I2 = 0%, high certainty for ruling out benefit of fresh blood, moderate certainty for ruling out harm of fresh blood). Transfusion of fresher red blood cells does not reduce overall or in-hospital mortality when compared with older red blood cells. Our results support the practice of transfusing patients with the oldest red blood cells available in the blood bank. © 2017 International Society of Blood Transfusion.

    Background Transfusion of blood components continues to be an important therapeutic resource into the 21st century. Between 5 and 58% of transfusions carried out are estimated to be unnecessary. According to several studies, at least 20% of packed red blood cell transfusions (RBCT) are administered in hospital emergency departments (ED), but few data are available about the appropriateness of RBCT in this setting. This multicentre, cross-sectional observational study aims to assess the appropriateness of RBCT indications and transfused volumes in patients who attend ED. Materials and methods The study cohort is made up of consecutive consenting adult patients (≥18 years old) who received RBCT in ED over a 3-month period and for whom relevant clinical data were collected and analysed. Results Data from 908 RBCT episodes (2±1 units per transfused patient) were analysed. RBCT was considered appropriate in 21.4% (n=195), with significant differences according to RBCT indication (p<0.001), hospital level (p<0.001) and prescribing physician (p=0.002). Pre-transfusion haemoglobin level (Hb) negatively correlated with RBCT appropriateness (r=–0.616; p<0.01). Only 72.4% of appropriate RBCT had a post-transfusion Hb assessment (n=516). Of these, 45% were considered to be over-transfused (n=232), with significant differences according to RBCT indication (p=0.012) and prescribing physician (p=0.047). Overall, 584/1,433 (41%) of evaluable RBC units were unnecessarily transfused. Discussion The appropriateness of RBCT in ED is similar to other hospital departments, but the rate of over-transfusion was high. These data support the need for a reassessment after transfusion of each RBC unit before further units are prescribed. In view of these results, we recommend that physicians should be made more aware of the need to prescribe RBCT appropriately in order to reduce over-transfusion. PMID:27416566

    Extremely preterm infants receive frequent blood transfusions in the first week of life. The aim of this study was to measure the effect of blood transfusion on intestinal blood flow and oxygenation during the first week of life in extremely preterm infants. Superior mesenteric artery (SMA) peak systolic velocity (PSV) and diastolic velocities were measured 30 to 60 minutes before and after transfusion. Splanchnic tissue hemoglobin index (sTHI), splanchnic tissue oxygenation index (sTOI), and splanchnic fractional tissue oxygen extraction (sFTOE) were measured continuously from 15 to 20 minutes before to after transfusion along with vital variables. Twenty infants were studied (median gestational age, 26 weeks). Ten infants were partially fed (15-68 mL/kg/day). Heart rate and SaO2 remained unaltered; blood pressure increased significantly (p transfusion. Mean SMA PSV (p = 0.63) and diastolic velocity (p = 0.65) remained unaltered. Mean pretransfusion SMA PSV was similar in partially fed (0.78 m/sec) compared to unfed infants (0.52 m/sec; p = 0.06) and the response to transfusion was not dissimilar. There was a significant increase in sTHI (mean difference, 32.3%; p transfusion. There was no significant difference in sTHI or sTOI between fed and unfed infants and their response to transfusion. Blood transfusion increased blood pressure and intestinal tissue oxygenation but did not alter blood flow velocities. Partial feeding had no impact on intestinal blood flow and tissue oxygenation changes. © 2015 AABB.

    Red blood cell transfusion is common in critically ill children after cardiac surgery. Since the threshold for hemoglobin (Hb) transfusion need is not well defined, the threshold Hb level at which dependent critical oxygen uptake-to-delivery (VO2-DO2) status compensation is uncertain. To assess the effects of blood transfusion on the oxygen extraction ratio (O2ER) and central venous oxygen saturation (ScvO2) to identify a critical O2ER value that could help us determine the critical need for blood transfusion. Prospective, observational cohort study. Cardiac Surgical Intensive Care Unit at Prince Sultan Cardiac Center in Qassim, Saudi Arabia. Between January 2013 and December 2015, we included all children with cardiac disease who underwent surgery and needed a blood transfusion. Demographic and laboratory data with physiological parameters before and 1 and 6 hours after transfusion were recorded and O2ER before and 6 hours after transfusion was computed. Cases were divided into two groups based on O2ER: Patients with increased O2ER (O2ER > 40%) and normal patients without increased O2ER (O2ER transfusion. Changes in O2ER and ScvO2 following blood transfusion. Of 103 patients who had blood transfusion, 75 cases had normal O2ER before transfusion while 28 cases had increased O2ER before transfusion. Following blood transfusion, O2ER and ScvO2 improved in the group that had increased O2ER before transfusion, but not in the group that had normal O2ER before transfusion. The clinical and hemodynamic indicators O2ER and ScvO2 may be considered as markers that can indicate a need for blood transfusion. The limitation of this study is the small number of patients that had increased O2ER before transfusion. There were few available variables to assess oxygen consumption.

    Red blood cells (RBCs) units are the most requested transfusion product worldwide. Indications for transfusion include symptomatic anaemia, acute sickle cell crisis, and acute blood loss of more than 30% of the blood volume, with the aim of restoring tissue oxygen delivery. However, stored RBCs from donors are not a qualitative equal product, and, in many ways, this is a matter of concern in the transfusion practice. Besides donor-to-donor variation, the storage time influences the RBC unit at the qualitative level, as RBCs age in the storage bag and are exposed to the so-called storage lesion. Several studies have shown that the storage lesion leads to post-transfusion enhanced clearance, plasma transferrin saturation, nitric oxide scavenging and/or immunomodulation with potential unwanted transfusion-related clinical outcomes, such as acute lung injury or higher mortality rate. While, to date, several studies have claimed the risk or deleterious effects of “old” vs “young” RBC transfusion regimes, it is still a matter of debate, and consideration should be taken of the clinical context. Transfusion-dependent patients may benefit from transfusion with “young” RBC units, as it assures longer inter-transfusion periods, while transfusion with “old” RBC units is not itself harmful. Unbiased Omics approaches are being applied to the characterisation of RBC through storage, to better understand the (patho)physiological role of microparticles (MPs) that are found naturally, and also on stored RBC units. Perhaps RBC storage time is not an accurate surrogate for RBC quality and there is a need to establish which parameters do indeed reflect optimal efficacy and safety. A better Omics characterisation of components of “young” and “old” RBC units, including MPs, donor and recipient, might lead to the development of new therapies, including the use of engineered RBCs or MPs as cell-based drug delivering tools, or cost-effective personalised transfusion

    Post-transfusion reactions with dyspnoea (PTR) are major causes of morbidity and death after blood transfusion. Transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO) are most dangerous, while transfusion-associated dyspnoea (TAD) is a milder respiratory distress. We investigated blood components for immune and non-immune factors implicated in PTR. We analysed 464 blood components (RBCs, PLTs, L-PLTs, FFP) transfused to 271 patients with PTR. Blood components were evaluated for 1/antileucocyte antibodies, 2/cytokines: IL-1β, IL-6, IL-8, TNF-α, sCD40L, 3/lysophosphatidylcholines (LysoPCs), 4/microparticles (MPs) shed from plateletes (PMPs), erythrocytes (EMPs) and leucocytes (LMPs). Anti-HLA class I/II antibodies or granulocyte-reactive anti-HLA antibodies were detected in 18.2% of blood components (RBC and FFP) transfused to TRALI and in 0.5% of FFP transfused to TAD cases. Cytokines and LysoPCs concentrations in blood components transfused to PTR patients did not exceed those in blood components transfused to patients with no PTR. Only EMPs percentage in RBCs transfused to patients with TRALI was significantly higher (P Blood Transfusion.

    Full Text Available AIMS: For elective surgeries, over ordering of blood is a common practice. This can be decreased by simple means of changing the blood cross matching and ordering schedule depending upon the type of surgery performed. The principle aim of the study was to improve the efficacy of ordering system for maximum utilisation of blood and formulation of maximum surgical blood order schedule (MSBOS for procedures where a complete cross-match appears mandatory. MATERIAL AND METHODS: We evaluated blood ordering and transfusion practices in 500 elective general surgical procedures at our institute. With the help of different indices such as cross-match to transfusion ratio (C/T ratio, transfusion probability (% T and transfusion index (TI, blood ordering pattern was changed in the next 150 patients. RESULTS: Out of 1145 units of blood crossmatched for the first 500 patients only 265 were transfused with non-utilisation of 76.86% of ordered blood. With the help of the indices the wastage was reduced in next 150 patients, i.e. from 76.86% to 25.26% and improved the utilisation of blood, i.e. from 23.14% to 74.74%. CONCLUSIONS: Change of blood ordering patterns with use of MSBOS can avoid the over ordering of blood.

    Full Text Available Background: During orthotopic liver transplantation (OLT, activation of the fibrinolytic system can contribute significantly to perioperative bleeding. Prophylactic administration of antifibrinolytic agents has been shown to reduce blood loss and the need for allogenic transfusion. Objective: To study the effect of antifibrinolytics on requirement of blood components, blood loss and operative time during OLT in patients with end stage liver disease, reporting to a single centre. Materials and Methods: Consecutive patients who underwent OLT at this centre during the period February 2003-October 2007 were the subjects of this study. Based on the individual anesthesiologist′s preference, patients were assigned to receive either two million units of aprotinin (AP as a bolus followed by 5,00,000 units/hour or 10 mg/kg tranexamic acid (TAas a bolus followed by 10 mg/kg every six to eight hours, administered from the induction till the end of the surgery. Transfusion policy was standardized in all patients. Intraoperative red cell salvage was done wherever possible. The effect of these two antifibrinolytic drugs on transfusion requirement was evaluated as a whole and in a sub group of patients from each treatment group and compared with a concurrent control group that did not receive antifibrinolytic drugs. Results: Fifty patients (40 M / 10 F, 44 adults, 6 pediatric patients underwent OLT in the study period. Fourteen patients were given AP, 25 patients were given TA and 11 patients did not receive any of the agents(control group. The median volume of total blood components transfused in antifibrinolytic group (n=39 was 4540 ml(0-19,200ml, blood loss 5 l(0.7-35l and operative time 9h (4.5-17h and that of control group(n=11 was 5700 ml(0-15,500ml, 10 l(0.6-25 l and 9h (6.4-15.8h respectively.

    Total shoulder arthroplasty (TSA) may be associated with substantial blood loss, and some patients require perioperative blood transfusion. Possible blood transfusion methods include predonated autologous blood transfusion, perioperative autologous blood transfusion, and allogeneic blood transfusion (ALBT). The purposes of the present study were to assess the incidence and recent trends over time of blood transfusion in TSA and analyze patient and hospital characteristics that affect the risk of ALBT. This study used national hospital discharge data from the National Inpatient Sample between 2000 and 2009. The data were used to generate the overall blood transfusion rate, and linear regression was used to assess trends in transfusion patterns over time. Logistic regression analysis was performed to analyze which patient and hospital characteristics independently influence the likelihood that a given patient undergoes ALBT. The overall blood transfusion rate (ie, the proportion of patients who received at least 1 transfusion of any kind) was 6.7%. This rate increased over time, from 4.9% in 2000 to 7.1% in 2009 (P blood transfusion rate in TSA found in the present study may be related to factors specific to TSA, such as the introduction of reverse total shoulder arthroplasty during the study period. A variety of patient and hospital characteristics contribute to the risk of undergoing ALBT. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

    The aim of this study was to assess current practices around obtaining consent for blood transfusion and provision of patient information in hospitals across the UK and identify areas for improvement. Recommendations from the Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) (2011) state that valid consent should be obtained for blood transfusion and documented in clinical records. A standardised source of information should be available to patients. Practices in relation to this have historically been inconsistent. The consent process was studied in hospitals across the UK over a 3-month period in 2014 by means of an audit of case notes and simultaneous surveys of patients and staff. In total, 2784 transfusion episodes were reviewed across 164 hospital sites. 85% of sites had a policy on consent for transfusion. Consent was documented in 43% of case notes. 68% of patients recalled being given information on benefits of transfusion, 38% on risks and 8% on alternatives and 28% reported receiving an information leaflet. In total, 85% of staff stated they had explained the reason for transfusion, but only 65% had documented this. 41% of staff had received training specifically on transfusion consent in the last 2 years. There is a need to improve clinical practice in obtaining valid consent for transfusion in line with existing national guidelines and local Trust policies, with emphasis on documentation within clinical records. Provision of patient information is an area particularly highlighted for action, and transfusion training for clinicians should be strengthened. © 2017 British Blood Transfusion Society.

    Red blood cell transfusion is the most common procedure in hospitalized patients in the US. Growing evidence suggests that a sizeable percentage of these transfusions are inappropriate, putting patients at significant risk and increasing costs to the health care system. We performed a retrospective quasi-experimental study from November 2008 until November 2014 in a 576-bed tertiary care hospital. The intervention consisted of an interruptive clinical decision support alert shown to a provider when a red blood cell transfusion was ordered in a patient whose most recent hematocrit was ≥21%. We used interrupted time series analysis to determine whether our primary outcome of interest, rate of red blood cell transfusion in patients with hematocrit ≥21% per 100 patient (pt) days, was reduced by the implementation of the clinical decision support tool. The rate of platelet transfusions was used as a nonequivalent dependent control variable. A total of 143,000 hospital admissions were included in our analysis. Red blood cell transfusions decreased from 9.4 to 7.8 per 100 pt days after the clinical decision support intervention was implemented. Interrupted time series analysis showed that significant decline of 0.05 (95% confidence interval [CI], 0.03-0.07; P clinical decision support tool. There was no statistical change in the rate of platelet transfusion resulting from the intervention. The implementation of an evidence-based clinical decision support tool was associated with a significant decline in the overuse of red blood cell transfusion. We believe this intervention could be easily replicated in other hospitals using commercial electronic health records and a similar reduction in overuse of red blood cell transfusions achieved.

    Intrauterine fetal transfusion needs extensive experience and requires excellent eye-hand coordination, good equipment and experienced team workers to achieve success. While the needle is in the umbilical vein, an assistant withdraws and/or transfuses blood. The needle point should be kept still to prevent lacerations and dislodging. We propose a simple set for Intrauterine Fetal blood transfusion is constructed by readily available materials in every clinic to minimize needle tip movement and movements during syringe attachments and withdrawals during the intrauterine fetal transfusion. This makes possible to withdraw fetal blood sample, and to transfuse blood with minimal intervention.

    Most blood transfusions occur in female patients. The introduction of serologic screening practices by blood banks reduced the transfusion-related rate of infection with hepatitis C virus (HCV). In Mexico patients with pre-1994 transfusion history are at high risk of being detected with HCV infection. We aimed at establishing an interrelationship between two variables: pre-1994 transfusion history and rate of infection in women treated in the Guadalajara Metropolitan Area hospitals, in Mexico. Analytical observational case-control study which included both non-infected women and patients diagnosed with hepatitis C virus infection, in whom the pre-1994 transfusion history was determined. The cases were 150 women with confirmed hepatitis C virus serologic diagnosis. The controls were 150 women whose hepatitis C virus-detection serologic tests had yielded negative results. An odds ratio of 9.07 (95% CI: 5.37 – 15.3; p< 0.001) was found where the rate of infection for the case group was 0.72 while the control group had a ratio of 0.22; population attributable risk (PAR) was 0.64 (95% CI: 0.53 – 0.73), while etiologic fraction was 0.88 (95% CI: 0.81 – 0.93). Among women, having been exposed to pre-1994 blood transfusion means a risk 9.07 times higher than not being exposed to blood transfusion in the same time frame.

    Background and purpose Hip fracture (HF) in frail elderly patients is associated with poor physical recovery and death. There is often postoperative blood loss and the hemoglobin (Hb) threshold for red blood cell (RBC) transfusions in these patients is unknown. We investigated whether RBC transfusion strategies were associated with the degree of physical recovery or with reduced mortality after HF surgery. Patients and methods We enrolled 284 consecutive post-surgical HF patients (aged ? 65 y...

    Despite advances in surgical techniques for spinal metastases, there is often substantial blood loss, resulting in patients requiring blood transfusion during the perioperative period. Allogeneic blood transfusion (ABT) has been the main replenishment method for lost blood. However, the impact of ABT on cancer-related outcomes has been controversial in various studies. We aimed to evaluate the influence of perioperative ABT on disease progression and survival in patients undergoing metastatic spinal tumor surgery (MSTS). We conducted a retrospective study that included 247 patients who underwent MSTS at a single tertiary institution between 2005 and 2014. The impact of using perioperative ABT (either exposure to or quantities of transfusion) on disease progression and survival was assessed using Cox regression analyses while adjusting for potential confounding variables. Of 247 patients, 133 (54%) received ABT. The overall median number of blood units transfused was 2 (range, 0-10 units). Neither blood transfusion exposure nor quantities of transfusion were associated with overall survival (hazard ratio [HR], 1.15 [p = 0.35] and 1.10 [p = 0.11], respectively) and progression-free survival (HR, 0.87 [p = 0.18] and 0.98 [p = 0.11], respectively). The factors that influenced overall survival were primary tumor type and preoperative Eastern Cooperative Oncology Group performance status, whereas primary tumor type was the only factor that had an impact on progression-free survival. This is the first study providing evidence that disease progression and survival in patients who undergo MSTS are less likely to be influenced by perioperative ABT. The worst oncologic outcomes are more likely to be caused by the clinical circumstances necessitating blood transfusion, but not transfusion itself. However, because ABT can have a propensity toward developing postoperative infections, including surgical site infection, the use of patient blood management

    Several observational and preclinical studies have shown that blood transfusion may modify the mortality of patients with myocardial infarction (MI). The aim of this meta-analysis is to evaluate the recent evidence on the effectiveness of blood transfusion for all-cause mortality in patients with MI. PUBMED, EMBASE and the Cochrane central register of controlled trials were searched up to June 2016 by two independent investigators. Studies were considered eligible if they recruited adult MI patients and reported hazard ratio (HR) for all-cause mortality comparing those who received blood transfusion with those who did not receive blood transfusion. We abstracted and calculated pooled HRs using a random-effects model. From 4277 unique reports, we identified 17 studies including 260811 patients with 11 studies examining short-term (in hospital/30-day) all-cause mortality and 9 studies examining long-term (more than 30 days) all-cause mortality. Meta-analysis demonstrated that patients treated with blood transfusion had increased short-term all-cause mortality (HR, 2.39, 95% CI 1.81 to 3.15) compared with those without blood transfusion treatment. Similar findings were observed by subgroup analyses. We also find significant association between blood transfusion and long-term all-cause mortality (HR 1.90, 95% CI 1.40 to 2.58) for MI patients. In patients with MI, blood transfusion treatment is associated with patient short-term and long-term all-cause mortality. However, further large-scale prospective studies are needed to establish its validity of this association.

To report clinical and laboratory variables of dogs receiving pRBC transfusion, which could guide transfusion of other anemic dogs. Twenty-four client-owned anemic dogs receiving pRBC transfusion. Prospective study; 30 transfusions assessed. Clinical findings (mucosal color, pulse quality, heart rate, respiratory rate, mentation/exercise tolerance) before and after transfusion were evaluated by the anemic dog clinical assessment score (ADCAS). Hemoglobin concentration, hematocrit, venous oxygen content (CvO2 ), and lactate concentration were measured from blood samples taken before and after transfusion. These results were not used for case management. All ADCAS variables decreased significantly with transfusion (P guiding the decision to transfuse dogs with similar presentations.

    Background and objective As epidemiological information is useful in planning the provision and assessing the efficiency of product use, we reviewed Spanish data on population, blood donation and blood component transfusion from 1997 to 2007, and the possible effect of universal leucoreduction. Methods Data on the Spanish population were obtained from the National Institute of Statistics, whereas data on blood donation and blood component transfusion were acquired from the Spanish Ministry of Health. Results During the study period, the Spanish population increased by 5.6 million persons (14.4%), and blood donation by 28.1%, although the amount of red blood cells (RBC) obtained increased by only 21.5% whereas RBC transfusions increased by 28.3%. The RBC transfusion rate was significantly higher after the implementation of universal leucoreduction (2002 – 2006) than during the pre-leucoreduction period (1997 – 2001) (differ ence = 2.54 units/1,000 population/year; 95%CI 1.81 – 3.27; P<0.001). We also observed statistical ly, but not clinically, significant differences for platelet and plasma transfusions. Conclusion The increase observed in the RBC transfusion index after implementation of universal leucoreduction may have been due to a reduction of the haemoglobin content in the RBC units. Our data on blood use do, therefore, seem to add to the case against universal leucoreduction, which has led to an incremental cost for unknown, but probably slight, benefits for patients.

    Bleeding and allogeneic transfusion remain constant problems in cardiac surgical procedures. In this study, we aimed to test the role of a routine thromboelastography (TEG)-based algorithm on bleeding and transfusions in patients undergoing elective coronary artery bypass grafting (CABG). Patients (n = 224) undergoing elective CABG with cardiopulmonary bypass were prospectively randomized into two groups according to transfusion strategy: in group 1 (clinician-directed transfusion, n = 110) need for blood transfusion was based on clinician's discretion and standard coagulation tests and in group 2 (TEG algorithm group, n = 114) kaolin-activated (k) TEG-based algorithm-guided perioperative transfusion management. Transfusion, blood loss, and outcome data were recorded. There were no differences in consumption of packed cell units, blood loss, re-exploration for bleeding, and early clinical outcome between the groups. Patients in the TEG group had significantly lower median units of fresh frozen plasma and platelets compared with the other group (p = 0.001). The median number of total allogeneic units transfused (packed cells and blood products) was significantly reduced in the TEG group compared with the other group (median 2, range 1-3 units vs. median 3, range 2-4 units, respectively, p = 0.001). The need for tranexamic acid was significantly diminished in the TEG group compared with the other group (10.3% vs. 19%, respectively, p = 0.007). Our results show that routine use of a kTEG-guided algorithm reduces the consumption of blood products in patients undergoing elective CABG. Adopting such an algorithm into routine management of these patients may help to improve clinical outcome and reduce the potential risks of transfusion-related complications and total costs after CABG.

    Prediction of blood transfusion requirement in trauma patients is a dilemma in most trauma centers. The aim of the current study was assessing the accuracy of emergency transfusion score (ETS) in detecting patients' need for blood transfusion in ED. In this cross-sectional study, all multiple trauma patients referred to the emergency department (ED) of Imam Hossein Hospital, Tehran, Iran, from March to August 2014, were enrolled. ETS parameters including low blood pressure, free fluid on ultrasound, clinical instability of the pelvic ring, age, admission from the scene, and trauma mechanism were recorded for all patients. ETS was calculated for all patients and compared with patients who received blood transfusion to estimate the accuracy of ETS. Of the 793 patients included in the study, 54 (6%) received blood in the ED. The mean of ETS for all patients was 3.91 ± 0.93. There was a significant correlation between ETS more than 3 and amount of blood transfusion ( P = 0.004). The sensitivity, specificity, positive, and negative predictive value of ETS was 98.1%, 13.8%, 7.7%, and 99%, respectively. ETS may be considered as a useful instrument for prioritizing multiple trauma patients' need for blood transfusion in Iran. Therefore, by implementing this score, it may be prevented from inappropriate requests for blood transfusion.

    Globally, as in South Africa, obstetric hemorrhage (OH) remains a leading cause of maternal mortality and morbidity. Although blood transfusion is critical to OH management, the incidence and predictors of transfusion as well as their relation to human immunodeficiency virus (HIV) infection are poorly described. A cross-sectional study was conducted of all peripartum patients at four major hospitals in South Africa (April to July 2012). Comprehensive clinical data were collected on patients who sustained OH and/or were transfused. Logistic regression was used to model risk factors for OH and transfusion. A total of 15,725 peripartum women were evaluated, of whom 3969 (25.2%) were HIV positive. Overall, 387 (2.5%) women sustained OH and 438 (2.8%) received transfusions, including 213 (1.4%) women with both OH and transfusion. There was no significant difference in OH incidence between HIV-positive (2.8%) and HIV-negative (2.3%) patients (adjusted odds ratio [OR], 0.95; 95% confidence interval [CI], 0.72-1.25). In contrast, the incidence of blood transfusion was significantly higher in HIV-positive (3.7%) than in HIV-negative (2.4%) patients (adjusted OR, 1.52; 95% CI, 1.14-2.03). Other risk factors for transfusion included OH, low prenatal hemoglobin, the treating hospital, lack of prenatal care, and gestational age of not more than 34 weeks. In the South African obstetric setting, the incidence of peripartum blood transfusion is significantly higher than in the United States and other high-income countries while OH incidence is similar. While OH and prenatal anemia are major predictors of transfusion, HIV infection is a common and independent contributing factor. © 2015 AABB.

    Massive transfusion of D- trauma patients in the combat setting involves the use of D+ red blood cells (RBCs) or whole blood along with suboptimal pretransfusion test result documentation. This presents challenges to the transfusion service of tertiary care military hospitals who ultimately receive these casualties because initial D typing results may only reflect the transfused RBCs. After patients are stabilized, mixed-field reaction results on D typing indicate the patient's true inherited D phenotype. This case series illustrates the utility of automated gel column agglutination in detecting mixed-field reactions in these patients. The transfusion service test results, including the automated gel column agglutination D typing results, of four massively transfused D- patients transfused D+ RBCs is presented. To test the sensitivity of the automated gel column agglutination method in detecting mixed-field agglutination reactions, a comparative analysis of three automated technologies using predetermined mixtures of D+ and D- RBCs is also presented. The automated gel column agglutination method detected mixed-field agglutination in D typing in all four patients and in the three prepared control specimens. The automated microwell tube method identified one of the three prepared control specimens as indeterminate, which was subsequently manually confirmed as a mixed-field reaction. The automated solid-phase method was unable to detect any mixed fields. The automated gel column agglutination method provides a sensitive means for detecting mixed-field agglutination reactions in the determination of the true inherited D phenotype of combat casualties transfused massive amounts of D+ RBCs.

    During the Spanish Civil War, Dr. Norman Bethune instituted a research laboratory to determine whether the blood from cadavers could be transfused into wounded soldiers and civilians at the front. Dr. Herman J. Muller joined him in this effort carrying out extensive experimentation into the technique and practice of such transfusions. At the same time, Bethune was in frequent contact with Dr. Reginald Saxton who later publicly advocated that the Spanish government should organize a large-scale supply of cadaver blood to the front-line hospitals. Recent evidence suggests that Saxton carried out cadaveric transfusions to an extent not previously recognized.

    Full Text Available Objective: Greece is ranked as the second highest consumer of blood components in Europe. For an effective transfusion system and in order to reduce variability of transfusion practice by implementing evidence-based transfusion guidelines it is necessary to study and monitor blood management strategies. Our study was conducted in order to evaluate the use of red blood cell units (RBC-U in nationwide scale mapping parameters that contribute to their proper management in Greece. Materials and Methods: The survey was conducted by the Working Committee of Transfusion Medicine&Apheresis of the Hellenic Society of Hematology from January to December 2013. The collected data included the number, ABO/D blood group, patients’ department, and storage age of RBC-U transfused. Results: The number of RBC-U evaluated was 103,702 (17.77% out of 583,457 RBC-U transfused in Greece in 2013. RBC-U transfused by hospital department (mean percentage was as follows: Surgery 29.34%, Internal Medicine 29.48%, Oncology/Hematology 14.65%, Thalassemia 8.87%, Intensive Care Unit 6.55%, Nephrology 1.78%, Obstetrics/Gynecology 1.46%, Neonatal&Pediatric 0.31%, Private Hospitals 8.57%. RBC-U distribution according to ABO/D blood group was: A: 39.02%, B: 12.41%, AB: 5.16%, O: 43.41%, D+: 87.99%, D-: 12.01%. The majority of RBC-U (62.46% was transfused in the first 15 days of storage, 25.24% at 16 to 28 days, and 12.28% at 29-42 days. Conclusion: Despite a high intercenter variability in RBC transfusions, surgical and internal medicine patients were the most common groups of patients transfused with an increasing rate for internal medicine patients. The majority of RBC-U were transfused within the first 15 days of storage, which is possibly the consequence of blood supply insufficiency leading to the direct use of fresh blood. Benchmarking transfusion activity may help to decrease the inappropriate use of blood products, reduce the cost of care, and optimize the use of the

    Full Text Available Abstract Background Oesophagectomy for cancers is a major operation with significant blood loss and usage. Concerns exist about the side effects of blood transfusion, cost and availability of donated blood. We are not aware of any previous study that has evaluated predictive factors for perioperative blood transfusion in patients undergoing elective oesophagectomy for cancer. This study aimed to audit the pattern of blood crossmatch and to evaluate factors predictive of transfusion requirements in oesophagectomy patients. Methods Data was collected from the database of all patients who underwent oesophagectomy for cancer over a 2-year period. Clinico-pathological data collected included patients demographics, clinical factors, tumour histopathological data, preoperative and discharge haemoglobin levels, total blood loss, number of units of blood crossmatched pre-, intra- and postoperatively, number of blood units transfused, crossmatched units reused for another patient and number of blood units wasted. Clinico-pathological variables were evaluated and logistic regression analysis was performed to determine which factors were predictive of blood transfusion. Results A total of 145 patients with a male to female ratio of 2.5:1 and median age of 68 (40–85 years were audited. The mean preoperative haemoglobin (Hb was 13.0 g/dl. 37% of males (Hb 70 years, Hb level Conclusion The cohort of patients audited was over-crossmatched. The identified independent predictors of blood transfusion should be considered in preoperative blood ordering for oesophagectomy patients. This study has directly led to a reduction in the maximum surgical blood-ordering schedule for oesophagectomy to 2 units and a reaudit is underway.

    The authors trace the history of blood transfusion in the Democratic Republic of Congo, as inherited through the colonial organization of the health system. The current configuration of transfusion system begins with the drafting of the national blood transfusion policy and the establishment of a national technical office within the Ministry of Health to coordinate transfusion activities and of its agents in each province. Despite countless difficulties, several positive points were noted. These involve essentially the drafting of all the necessary documents and standards and the integration of the blood safety system into the country's health system. Initially, the blood transfusion system applied a vertical approach, but with the reform of the country's health system, the performance of blood safety became transversal. In the 12 years from 2001 to 2012, it mobilized 112,882 volunteer blood donors; more than 80% of blood products were checked for safety and covered all blood needs; and 81,806 HIV infections were avoided by routine testing of blood products. During the same period, 7560 people were trained in blood transfusion. The prevalence of viral markers among donors has diminished sharply. Thus, HIV prevalence decreased from 4.7% to 2.1% between 2001 and 2012 that of hepatitis B dropped from 7.1% to 3.5% during the same period, and hepatitis C from 11.8% to 2.3% from 2004 to 2012. Despite this performance, enormous efforts are still required, for the organization of blood safety monitoring, the establishment of a safe supply of reagents and supplies, for sustaining the dynamics of voluntary associations of blood donors, and finally for providing stable funding for these blood safety activities.

    Procedures for the surgical correction of dentofacial deformities may produce important complications, whether due to the potential for vascular injury or to prolonged surgery, both of which may lead to severe blood loss. Fluid replacement with crystalloid, colloid, or even blood products may be required. The aim of this study was to assess blood loss and transfusion requirements in 45 patients (18 males and 27 females; mean age 29.29 years, range 16-52 years) undergoing orthognathic surgery, assigned to one of two groups according to procedure type-rapid maxillary expansion or double-jaw orthognathic surgery. Preoperative hemoglobin and hematocrit levels and intraoperative blood loss were measured. There was a substantial individual variation in pre- and postoperative hemoglobin values (10.3-17 and 8.8-15.4 g/dL, respectively; p surgery and follow meticulous protocols to minimize the risks.

    Risk-adjusted institutional transfusion rates are not currently available on a national level. A surrogate means of benchmarking transfusion practices to use for internal quality improvement was studied. Blood utilization was prospectively studied among all colorectal surgery patients at the study institution (July 2010-November 2012), and these data were benchmarked with transfusion data from the National Surgical Quality Improvement Program (NSQIP) database by hospital type and size. Using NSQIP, the study institution's colorectal surgery transfusion rate was 16.3% (150/920 cases), which was slightly higher than the 14.3% national mean transfusion rate (12 191/85 507 cases; P = .08). When broken down by hospital type and size, the study hospital had a similar rate of blood transfusion compared with academic hospitals (P = .35) but a significantly higher rate than community hospitals, regardless of patient volume (P = .03). Benchmarking blood utilization compared with similar-type hospitals using NSQIP may be a surrogate method to assess adherence to evidence-based transfusion guidelines and identify areas for structured quality improvement initiatives. © The Author(s) 2014.

    The association between lower preoperative hematocrit (Hct) and risk for morbidity/mortality after cardiac surgery is well established. We examined whether the impact of low preoperative Hct on outcome is modified by blood transfusion and operative risk in women and men undergoing nonemergent CABG surgery. Patients having nonemergent, first-time, isolated CABG were included (N=2757). Logistic regressions assessed effect of hematocrit on major perioperative morbidity/mortality separately by males (n=2232) and females (n=525). Mean age was 63.2±10.1years, preoperative hematocrit was 38.9±4.8%, and STS risk score was 1.3±1.8%. Blood transfusion was more likely in female patients (26% vs. 12%, Ptransfusion in males and females, whereas older age (OR=1.03, P=0.017) also predicted transfusion in females. Major morbidity was also more likely in female patients (12% vs. 7%, Pblood transfusion was the only predictive factor for major morbidity in females (OR=4.56, Pblood transfusion (OR=9.22, Pblood transfusion and major morbidities after nonemergent CABG. Traditional factors that have been found to predict outcomes, such as hematocrit and STS risk, were related only to major morbidity in male patients. However, blood transfusion negatively impacted major outcome after nonemergent CABG surgery across all STS risk levels in both genders. Copyright © 2015 Elsevier Inc. All rights reserved.

    This study reports electrolyte and acid/base disturbances observed in clinical cases receiving autologous transfusion of blood processed by a cell salvage device. The records of 12 client-owned dogs that received an autologous transfusion via a cell salvage device with pre- and post-autologous transfusion blood work available were reviewed. Blood work from the 12 case dogs was compared to blood work from 12 control dogs with similar diseases. Control dogs received similar surgical treatment and were administered a similar volume per kg of packed red blood cells as case dogs, but did not undergo autologous transfusion. Case dogs that received autologous transfusion via a cell salvage device were significantly more likely to experience a decrease in ionized calcium and magnesium levels post-transfusion than were control dogs. Calcium and magnesium levels should be closely monitored during and after autologous transfusion. Calcium and/or magnesium supplementation may be required.

    There are some theoretical concerns for the use of intraoperative cell salvage (ICS) in patients with ectopic pregnancy. This study aimed to observe the impact of ICS on the coagulation function and clinical outcomes of patients with ruptured ectopic pregnancy and severe blood loss. This was a retrospective study of 225 patients with ruptured ectopic pregnancy and severe blood loss treated at the Third Affiliated Hospital of Guangxi Medical University between January 2012 and May 2016. Patients were grouped according to ICS (n = 116) and controls (n = 109, allogenic transfusion and no transfusion). Compared with controls, patients with ICS had shorter hospitalization (P = 0.007), lower requirement for allogenic blood products (P < 0.001), and higher hemoglobin levels at discharge (P < 0.001). There were no complications/ adverse reactions. In the ICS group, hemoglobin at discharge (-6.5%, P = 0.002) and thrombin time (-3.7%, P = 0.002) were decreased 24 h after surgery, while 24 h APTT was increased (+4.6%, P < 0.001). In the control group, hemoglobin at discharge (-16.8%, P < 0.001) was decreased after surgery and 24 h APTT was increased (+2.4%, P = 0.045). At discharge, hemoglobin levels were higher in the ICS group (P < 0.001). ICS was associated with good clinical outcomes in patients with ruptured ectopic pregnancy and severe blood loss.

    Full Text Available Background: The Kenya National Blood Transfusion Service (KNBTS is mandated to provide safe and sufficient blood and blood components for the country. In 2013, the KNBTS National Testing Laboratory and the six regional blood transfusion centres were enrolled in the Strengthening Laboratory Management Toward Accreditation (SLMTA programme. The process was supported by Global Communities with funding from the United States Centers for Disease Control and Prevention.Methods: The SLMTA implementation at KNBTS followed the standard three-workshop series, on-site mentorships and audits. Baseline, midterm and exit audits were conducted at the seven facilities, using a standard checklist to measure progress. Given that SLMTA was designed for clinical and public health laboratories, key stakeholders, guided by Global Communities, tailored SLMTA materials to address blood transfusion services, and oriented trainers, auditors and mentors on the same.Results: The seven facilities moved from an average of zero stars at baseline to an average of three stars at the exit audit. The average baseline audit score was 38% (97 points, midterm 71% (183 points and exit audit 79% (205 points. The Occurrence Management and Process Improvement quality system essential had the largest improvement (at 67 percentage points, from baseline to exit, whereas Facilities and Safety had the smallest improvement (at 31 percentage points.Conclusion: SLMTA can be an effective tool for preparing a blood transfusion service for accreditation. Key success factors included customising SLMTA to blood transfusion activities; sensitising trainers, mentors and auditors on operations of blood transfusion service; creating SLMTA champions in key departments; and integrating other blood transfusion-specific accreditation standards into SLMTA.

    Full Text Available OBJECTIVE: To evaluate the association of clinical and demographic variables in patients requiring blood transfusion during elective surgery to treat scoliosis with the aim of identifying markers predictive of the need for blood transfusion. METHODS: Based on the review of medical charts at a public university hospital, this retrospective study evaluated whether the following variables were associated with the need for red blood cell transfusion (measured by the number of packs used during scoliosis surgery: scoliotic angle, extent of arthrodesis (number of fused levels, sex of the patient, surgery duration and type of scoliosis (neuromuscular, congenital or idiopathic. RESULTS: Of the 94 patients evaluated in a 55-month period, none required a massive blood transfusion (most patients needed less than two red blood cell packs. The number of packs was not significantly associated with sex or type of scoliosis. The extent of arthrodesis (r = 0.103, surgery duration (r = 0.144 and scoliotic angle (r = 0.004 were weakly correlated with the need for blood transfusion. Linear regression analysis showed an association between the number of spine levels submitted to arthrodesis and the volume of blood used in transfusions (p = 0.001. CONCLUSION: This study did not reveal any evidence of a significant association between the need for red blood cell transfusion and scoliotic angle, sex or surgery duration in scoliosis correction surgery. Submission of more spinal levels to arthrodesis was associated with the use of a greater number of blood packs.

    Blood loss during total knee arthroplasty (TKA) remains a concern, as many patients require blood transfusions, which increase risks of allergic reactions, disease transmission, and thromboembolisms. The purpose was to determine factors associated with blood loss and need for transfusion in patients receiving routine TKA. The authors prospectively analyzed 150 consecutive uncemented TKAs for age, gender, body mass index (BMI), anticoagulant medication, type of anesthesia, tranexamic acid (TXA) administration, tourniquet inflation, drain placement, pre- and post-operative Haemoglobin (Hb) level (g/dL), and whether transfusion was necessary. Univariable and multivariable regression analyses were performed to identify factors associated with Hb loss and need for transfusion with significance level set at P valueloss was 3.7±1.3 g/dL. The 20 patients (13%) who had transfusions also had lower preoperative Hb (12.6±1.2 g/dL) compared to the remaining patients (14.3±1.2 g/dL). Hb loss was significantly associated with preoperative Hb, TXA, and gender, but multivariable regression identified gender as a confounder and indicated that TXA reduced Hb loss by 0.92 g/dL. Multivariable regression revealed the need for transfusion was only significantly associated with preoperative Hb and indicated that a decrease of preoperative Hb by 1 g/dL nearly quadrupled the chances of needing transfusion. Hb loss was significantly associated with preoperative Hb levels and use of TXA, while the need for transfusion was only associated with preoperative Hb levels. These findings could help identify patients at risk for blood transfusions. Level of evidence: level III, prospective case series.

    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.

    Full Text Available Introduction: Children having hemolytic anemias who have received multiple blood transfusions exhibit a rare complication of development of hypertension and seizures following transfusion, which may or may not be associated with intracranial hemorrhage. Case description: A 9-year-old boy presented with history of progressive paleness of body and weakness for the 30 days. There was a history of blood transfusion one week ago and multiple transfusions for one year of age. Examination revealed tachycardia, tachypnea, severe pallor and splenohepatomegaly. Blood work revealed a hemoglobin level of 4.0 grams with peripheral smear findings suggestive of hemolytic anemia. After blood transfusion, child complained of difficulty in breathing, vomiting and visual loss, followed by convulsions. Blood pressure was 180/110 mmHg. Seizure was controlled with intravenous midazolam and hypertension with furosemide and labetalol. CT brain was normal. As hypertension got under control, child gradually gained consciousness. Conclusion: A less intensive transfusion regimen among such patients along with prompt management of hypertension can prevent this potentially fatal syndrome.

    Summary Haematology and blood transfusion, as a clinical and laboratory discipline, has a far-reaching impact on healthcare both through direct patient care as well as provision of laboratory and transfusion services. Improvement of haematology and blood transfusion may therefore be significant in achieving advances in health in Africa. In 2005, Tanzania had one of the lowest distributions of doctors in the world, estimated at 2·3 doctors per 100 000 of population, with only one haematologist, a medical doctor with postgraduate medical education in haematology and blood transfusion. Here, we describe the establishment and impact of a postgraduate programme centred on Master of Medicine and Master of Science programmes to build the capacity of postgraduate training in haematology and blood transfusion. The programme was delivered through Muhimbili University of Health and Allied Sciences (MUHAS) with partnership from visiting medical and laboratory staff from the UK and complemented by short-term visits of trainees from Tanzania to Haematology Departments in the UK. The programme had a significant impact on the development of human resources in haematology and blood transfusion, successfully training 17 specialists with a significant influence on delivery of health services and research. This experience shows how a self-sustaining, specialist medical education programme can be developed at low cost within Lower and Middle Income Countries (LMICs) to rapidly enhance delivery of capacity to provide specialist services.

    TACSI whole blood system is designed to combine primary and secondary processing of six whole blood bags into plasma units, buffy coat and red blood cell concentrates. The aim of this study was to investigate the specifications and in vitro storage parameters of blood components compared with standard centrifugation and separation processing. Whole blood bags, collected in CRC kits, were treated on a TACSI whole blood system. They were compared with whole blood bags collected in Composelect kits. In addition to routine quality control analyses, conservation studies were performed on red blood cell concentrates for 42 days and on plasma for 6 months. Platelets pools with five buffy coats were also created, and cellular contamination was evaluated. Red blood cell concentrates produced from TACSI whole blood met European quality requirements. For white blood cell count, one individual result exceeded 1 × 10(6) cells/unit. All plasma units fell within specifications for residual cellular contamination and storage parameters. The performances of the TACSI whole blood system allow for the preparation of low volume buffy coats with a recovery of 90% of whole blood platelets. Haemoglobin losses in TACSI BC are smaller, but this did not result in higher haemoglobin content of red cells. These BC are suitable for the production of platelet concentrates. From these in vitro data, red blood cell concentrates produced using TACSI whole blood are suitable for clinical use with a quality at least equivalent to the control group. © 2014 International Society of Blood Transfusion.

    With increasing appreciation of the possible adverse effects of peri-operative blood transfusion, restrictive policies regarding use of blood products have been adopted in many surgical specialties. Although microvascular breast reconstruction has become a routine procedure, high peri-operative transfusion rates continue to be reported in the literature. In this study we examine the impact of our restrictive approach on blood transfusion rates and postoperative complications in patients undergoing microvascular blood transfusion. A retrospective review of patients undergoing microvascular breast reconstruction with abdominal flaps at a single institution was performed. Patient age and body mass index as well as type, timing and laterality of reconstruction was recorded. Pre-operative and post-operative hemoglobin and hematocrit were recorded. Peri-operative blood transfusion rates were calculated. Post-operative complication rates were compared between patients with higher and lower post-operative hemoglobin levels. Five hundred and twelve patients were included in this study. The peri-operative transfusion rate was 0.98% in this series. There was no significant difference between transfusion rates in unilateral and bilateral reconstructions (0.68 vs 1.36% p = 0.08) or immediate and delayed reconstructions (1.02 vs 0.51% p = 0.72 and 1.01 vs 1.60% p = 0.09 for unilateral and bilateral respectively). Lower post-operative hemoglobin levels were not associated with increased flap related, surgical or medical complications rates. A restrictive approach to peri-operative blood transfusion can be safely adopted in microvascular breast reconstruction without compromising flap viability or overall complication rates.

    Leukocytes in allogeneic blood transfusions cause several immunomodulatory events. This before-and-after cohort study evaluated clinical outcomes after adoption of prestorage leukoreduction program for blood transfusions, with particular focus on acute kidney injury. One thousand thirty-four consecutive patients who underwent on-pump coronary artery bypass grafting between January 2004 and December 2007 were included. Propensity score analysis for transfusion was performed in the whole population; patients who were actually transfused were then divided according to leukoreduction. From these 2 groups, 147 pairs matched for propensity score were considered to evaluate with bivariate and multivariable analyses the effects of leukoreduction, with all-cause in-hospital mortality and morbidity as main outcomes. Unadjusted in-hospital mortalities were 6.6% for the entire cohort and 44.2% for those with acute kidney injury. In the matched population, after introduction of leukoreduction, mortality rates decreased to 5.4% (vs 11.4%) and acute kidney injury (RIFLE [Risk, Injury, Failure, Loss of function, End-stage renal disease] class R or greater) dropped from 51.7% to 41.5% (relative risk -20%, P < .045). No difference emerged regarding other major complications. At multivariable analysis, intra-aortic balloon pump, RIFLE score, and propensity score for transfusion proved independent predictors of in-hospital mortality. Intra-aortic balloon pump and nonleukodepleted transfusion emerged as independent predictors of acute kidney injury. Multivariable analysis on the overall cohort of transfused patients confirmed that nonleukodepleted transfusion was an independent predictor of acute kidney injury. Leukoreduction of allogeneic blood products is associated with decreased acute kidney injury and mortality in highly transfused patients. 2010 The American Association for Thoracic Surgery.

    BACKGROUND Blood transfusions are common in older adults, and also may modulate the immune system. However, the impact of transfusion on cancer risk in the elderly has not been studied. STUDY DESIGN AND METHODS Cancer risk after blood transfusion was evaluated in a U.S. population-based case-control study using 552,951 elderly cases identified from cancer registries and 100,000 frequency-matched controls. Transfusions received 0–12 months, 13–30 months and 31–48 months prior to cancer diagnosis or selection date were identified using Medicare claims. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regressions. A Bonferroni correction adjusted for multiple testing. RESULTS Transfusions received 0–12 months before cancer diagnosis/selection were associated with significantly elevated risk of cancer overall (OR=2.05; 95% CI: 1.95–2.16), and cancers of the stomach, colon, liver, kidney/renal pelvis/ureter, lymphoma, myeloma and leukemia. No significant associations for cancer overall were observed for the two earlier intervals. No site was associated with transfusions received 13–30 or 31–48 months before diagnosis/selection. Nonetheless, overall cancer risk increased with the number of transfused periods (p-trend < 0.0001). CONCLUSION Risk of overall cancer and specific sites was elevated 0–12 months after blood transfusion and associated with multiple transfusions, possibly due to reverse causation, i.e. incipient cancers or cancer precursors causing anemia.

    To compare clinical outcomes between restrictive versus liberal blood transfusion strategies in patients with coronary artery disease (CAD). A literature search from January 1966 to May 2016 was performed in PubMed, EMBASE and Cochrane Library to find trials evaluating a restrictive hemoglobin transfusion trigger of ≤8 g/dL, compared with a more liberal trigger. Two study authors independently extracted data from the trials. The primary outcome was mortality and the secondary outcome was subsequent myocardial infarction. Relative risks (RRs) with their 95% confidence intervals (CIs) were assessed. Six trials involving 133,058 participants were included in this study. Pooled results revealed no difference in mortality between the liberal transfusion and restrictive transfusions (RR = 1.17, 95% CI = 0.91-1.52, P = .22). Subgroup analysis revealed that a restrictive transfusion strategy was associated with a higher risk of in-hospital mortality (RR = 1.38, 95% CI = 1.15-1.67, P transfusion strategy and restrictive transfusion strategy in risk for subsequent myocardial infarction (RR = 1.09, 95% CI = 0.57-2.06, P = .80). Limitations include (1) limited number of trials, especially those evaluating myocardial infarction, (2) observed heterogeneity, (3) confounding by indication and other inherent bias may exist. The findings suggest that restrictive blood transfusion was associated with higher in-hospital and 30 day mortality than liberal blood transfusion in CAD patients. The conclusions are mainly based on retrospective studies and should not be considered as recommendation before they are supported by randomized controlled trials.

    Acute reduction in hemoglobin levels is frequently seen during sepsis. Previous studies have focused on the management of anemia in patients with septic shock admitted to intensive care units (ICU's), including aggressive blood transfusion aiming to enhance tissue oxygenation. To study the changes in hemoglobin concentrations during the first week of sepsis in the setting of Internal Medicine (IM) units, and their correlation to survival. Observational prospective study. We recorded hemoglobin values upon admission and throughout the first week of hospital stay in a consecutive cohort of septic patients admitted to IM units at a community hospital, the patients were enrolled into a prospective registry. Data on blood transfusions was also collected, we examined the correlation between hemoglobin concentrations during the first week of sepsis and survival, the effect of blood transfusion was also assessed. Eight hundred and fifteen patients (815) with sepsis were enrolled between February 2008 to January 2009. More than 20 % of them had hemoglobin levels less than 10g/dL on admission, a rate that was doubled during the first week of sepsis. Overall, 68 (8.3 %) received blood transfusions, 14 of them (20.6 %) due to bleeding. Typically, blood transfusion was given to older patients with a higher rate of malignancy and lower hemoglobin levels. While hemoglobin concentration on admission had strong correlation with in-hospital mortality (O.R-0.83 [95 % C.I. 0.74-0.92], blood transfusion was not found to be an independent predicting factor for mortality. Anemia is very common in sepsis. While hemoglobin level on admission exhibit independent correlation with survival, blood transfusion do not.

    Laboratory testing prior to blood transfusion outside of regular hours in many hospitals and clinics is frequently conducted by technicians without sufficient experience in such testing work. To obtain consistent test results regardless of the degree of laboratory experience with blood transfusion testing, the number of facilities introducing automated equipment for testing prior to blood transfusion is increasing. Our hospital's blood transfusion department introduced fully automated test equipment in October of 2010 for use when blood transfusions are conducted outside of regular hours. However, excessive dependence on automated testing can lead to an inability to do manual blood typing or cross-match testing when necessitated by breakdowns in the automated test equipment, in the case of abnormal specimen reactions, or other such case. In addition, even outside of normal working hours there are more than a few instances in which transfusion must take place based on urgent communications from clinical staff, with the need for prompt and flexible timing of blood transfusion test and delivery of blood products. To address this situation, in 2010 we began training after-hours laboratory personnel in blood transfusion testing to provide practice using test tubes manually and to achieve greater understanding of blood transfusion test work (especially in cases of critical blood loss). Results of the training and difficulties in its implementation for such after-hours laboratory personnel at our hospital are presented and discussed in this paper. [Original

    OBJECT A major challenge in sagittal craniosynostosis surgery is the high transfusion rate (50%-100%) related to blood loss in small pediatric patients. Several approaches have been proposed to prevent packed red blood cell (PRBC) transfusion, including endoscopic surgery, erythropoietin ortranexamic acid administration, and preoperative hemodilution. The authors hypothesized that a significant proportion of postoperative anemia observed in pediatric patients is actually dilutional. Consequently, since 2005, at CHU Sainte-Justine, furosemide has been administered to correct the volemic status and prevent PRBC transfusion. The purpose of this study was to evaluate the impact of postoperative furosemide administration on PRBC transfusion rates. METHODS This was a retrospective study of 96 consecutive patients with sagittal synostosis who underwent surgery at CHU Sainte-Justine between January 2000 and May 2012. The mean age at surgery was 4.9 ± 1.5 months (range 2.8-8.7 months). Patients who had surgery before 2005 constituted the control group. Those who had surgery in 2005 or 2006 were considered part of an implementation phase because furosemide administration was not routine. Patients who had surgery after 2006 were part of the experimental (or furosemide) group. Transfusion rates among the 3 groups were compared. The impact of furosemide administration on transfusion requirement was also measured while accounting for other variables of interest in a multiple logistic regression model. RESULTS The total transfusion rate was significantly reduced in the furosemide group compared with the control group (31.3% vs 62.5%, respectively; p = 0.009), mirroring the decrease in the postoperative transfusion rate between the groups (18.3% vs 50.0%, respectively; p = 0.003). The postoperative transfusion threshold remained similar throughout the study (mean hemoglobin 56.0 g/dl vs 60.9 g/dl for control and furosemide groups, respectively; p = 0.085). The proportion of

    Members of armed forces worldwide are considered to be very susceptible to sexually transmitted infections, thus falling into a high-risk group of blood donors regarding transfusion-transmissible infections. In the Serbian Military Medical Academy a significant number (44% for the period 2005-2013) of blood donations were from members of the Serbian Army. The aim of this study was to determine the significance of military blood donors for the safety of blood transfusion. Between January 2005 and December 2013, a total of 155,479 blood donations were tested for hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV) and syphilis using serological assays (enzyme immunoassays, chemiluminescent microparticle immunoassay and western blot) and molecular testing (polymerase chain reaction analysis). The percentage of blood donations positive for transfusion-transmissible infections in the estimated period was 0.38%, and the percentage of HBV, HCV, HIV and syphilis positive blood donations was 0.20%, 0.12%, 0.005% and 0.06%, respectively. During that period, the percentage of all transfusion-transmissible infections, and in particular of HBV and HCV, declined significantly. In contrast, the percentage of HIV and syphilis positive blood donations remained unchanged. Higher rates of positivity for transfusion-transmissible infections in blood donations from members of the Serbian Army were not found, especially after mandatory military service was abolished in 2009. The reported rate of positivity for transfusion-transmissible infections in blood donations from the Military Medical Academy was considered low. This information is of great significance for further implementation of public health measures.

    The issue of the clinical appropriateness of blood transfusion has become a focus of transfusion medicine worldwide. In China, irrational uses of blood have often been reported in recent years. However, to date there lacks a systematic review of the rational uses of blood. This study aimed to determine the clinical appropriateness of blood transfusion in China. We searched PubMed, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database, WanFang Database, and Chinese BioMedical Literature Database, and the retrieval cut-off date was June 31, 2015. SPSS 17.0 and MetaAnalyst 3.13 were employed as the statistics tools in this review. A pooled rate of clinical inappropriateness of transfusion was analyzed by DerSimonian-Laird method. In this study, a total of 39 observational studies were included, which related to 75,132 cases of blood transfusion. According to the meta-analysis results, the overall incidence of clinical inappropriateness of transfusion in China was estimated to be 37.3% (95% confidence interval [CI] [32.1, 42.8]). The subgroup analyses revealed that the pooled rates of clinical inappropriateness of transfusion of plasma, red blood cells (RBCs), cryoprecipitate, and platelets were 56.3% (95% CI [45.8, 66.2]), 30.9% (95% CI [27.1, 35.0]), 25.2% (95% CI [13.2, 42.7]), and 14.1% (95% CI [8.8, 21.9]), respectively. However, the pooled incidence of inappropriateness of transfusion in operative departments was 47.5% (95% CI [36.8, 58.3]), which was significantly higher than that in nonoperative departments, 25.8% (95% CI [18.7, 34.4], P  0.05). In conclusion, China has suffered from a disadvantage in the clinical appropriateness of blood transfusion, especially in plasma and RBC use. In future, comprehensive measures should be implemented in order to improve the clinical appropriateness of blood transfusion.

    Intraoperative blood transfusion increases the risk for perioperative mortality and morbidity in liver transplant recipients. A high stroke volume variation (SVV) method has been proposed to reduce blood loss during living donor hepatectomy. Herein, we investigated whether maintaining high SVV could reduce the need for blood transfusion and also evaluated the effect of the high SVV method on postoperative outcomes in liver transplant recipients. We retrospectively analyzed 332 patients who underwent liver transplantation, divided into control (maintaining blood transfusion requirement and hemodynamic parameters, including SVV, as well as postoperative outcomes, such as incidences of acute kidney injury, durations of postoperative intensive care unit and hospital stay, and rates of 1-year mortality. Mean SVV values were 7.0% ± 1.3% in the control group (n = 288) and 11.2% ± 1.8% in the high SVV group (n = 44). The median numbers of transfused packed red blood cells and fresh frozen plasmas in the high SVV group were significantly lower than those in control group (0 vs. 2 units, P = 0.003; and 0 vs. 3 units, P = 0.033, respectively). No significant between-group differences were observed for postoperative outcomes. Maintaining high SVV can reduce the blood transfusion requirement during liver transplantation without worsening postoperative outcomes. These findings provide insights into improving perioperative management in liver transplant recipients.

    There is growing clinical and policy emphasis on minimizing transfusion use in elective joint arthroplasty, but little is known about the degree to which transfusion rates vary across US hospitals. This study aimed to assess hospital-level variation in use of allogeneic blood transfusion in patients undergoing elective joint arthroplasty and to characterize the extent to which variability is attributable to differences in patient and hospital characteristics. The study population included 228,316 patients undergoing total knee arthroplasty (TKA) at 922 hospitals and 88,081 patients undergoing total hip arthroplasty (THA) at 606 hospitals from January 1, 2009 to December 31, 2011 in the Nationwide Inpatient Sample database, a 20% stratified sample of US community hospitals. The median hospital transfusion rates were 11.0% (interquartile range, 3.5%-18.5%) in TKA and 15.9% (interquartile range, 5.4%-26.2%) in THA. After fully adjusting for patient- and hospital-related factors using mixed-effects logistic regression models, the average predicted probability of blood transfusion use in TKA was 6.3%, with 95% of the hospitals having a predicted probability between 0.37% and 55%. For THA, the average predicted probability of blood transfusion use was 9.5%, with 95% of the hospitals having a predicted probability between 0.57% and 66%. Hospital transfusion rates were inversely associated with hospital procedure volume and directly associated with length of stay. The use of blood transfusion in elective joint arthroplasty varied widely across US hospitals, largely independent of patient case-mix and hospital characteristics. Copyright © 2016 Elsevier Inc.

    Blood is an important resource in several lifesaving interventions, such as anemia correction and improvement of oxygen transport capacity. Despite advances, packed red blood cell (PRBC) transfusion still involves risks. The aim of this study was to describe the knowledge of anesthesiologists about the indications, adverse effects, and alternatives to red blood cell transfusion intraoperatively. Cross-sectional study using a questionnaire containing multiple choice questions and clinical cases related to relevant factors on the decision whether to perform PRBC transfusion, its adverse effects, hemoglobin triggers, preventive measures, and blood conservation strategies. The questionnaire was filled without the presence of the investigator. Likert scale was used and the average rank of responses was calculated. The Epi Info 7 software was used for data analysis. 79% of the institution's anesthesiologists answered the questionnaire; 100% identified the main adverse effects related to blood transfusion. When asked about the factors that influence the transfusion decision, hemoglobin level had the highest agreement (MR=4.46) followed by heart disease (MR=4.26); hematocrit (MR=4.34); age (RM=4.1) and microcirculation evaluation (MR=4.22). Respondents (82.3%) identified levels of Hb=6g.dL-1 as a trigger to transfuse healthy patient. Regarding blood conservation strategies, hypervolemic hemodilution (MR=2.81) and decided by drugs (MR=2.95) were the least reported. We identify a good understanding of anesthesiologists about PRBC transfusion; however, there is a need for refresher courses on the subject. Copyright © 2017 Sociedade Brasileira de Anestesiologia.

    The question of independent association between allogeneic blood transfusion (ABT) and postoperative complications in cancer surgeries has been controversial and remains so. In metastatic spine tumor surgery (MSTS), previous studies investigated the influence of ABT on survival, but not on postoperative complications. We aimed to evaluate the influence of perioperative ABT on postoperative complications and infections in patients undergoing MSTS. This retrospective study included 247 patients who underwent MSTS at a single tertiary institution between 2005 and 2014. The outcome measures were postoperative complications and infections within 30 days after MSTS. Multivariate logistic regression analyses were performed to assess influence of blood transfusion on the outcomes after adjusting for potential confounders. Of 247 patients, 133 (54%) received ABT with overall median (range) of 2 (0-10) units. The adjusted odds of developing any postoperative complication was 2.27 times higher in patients with transfusion (95% confidence interval [CI], 1.17-4.38; p = 0.01) and 1.24 times higher odds per every unit increase in blood transfusion (95% CI, 1.05-1.46; p blood transfusion also increased the odds of having overall postoperative infections (odds ratio, 3.58; 95% CI, 1.15-11.11; p = 0.02) and there were 1.24 times higher odds per every unit increase in transfusion (95% CI, 1.01-1.54; p = 0.04). This study adds evidence to the literature implicating ABT to be influential on postoperative complications and infections in patients undergoing MSTS. Appropriate blood management measures should, therefore, be given a crucial place in the care of these patients so as to reduce any putative effect of blood transfusion. © 2017 AABB.

    To determine whether epsilon-aminocaproic acid (EACA) load of 50 mg∙kg -1 before skin incision, and infusion of 25 mg∙kg -1 ∙h -1 until skin closure during cranial vault reconstruction (CVR) were associated with decreased estimated blood loss and transfusion requirements. Antifibrinolytic medications decrease bleeding and transfusion requirements during cardiothoracic and orthopedic surgeries with high blood loss, but practical reductions in blood loss and transfusion requirements have not been consistently realized in children undergoing CVR. Current dosing recommendations are derived from adult extrapolations, and may or may not have clinical relevance. Retrospective case-controlled study of 45 consecutive infants and children undergoing primary craniosynostosis surgery at Covenant Children's Hospital during years 2010-2014. Exclusion criteria included revision surgery, and chromosomal abnormalities associated with bleeding disorders. Blood loss and blood transfusion volumes as a percent of estimated blood volume were compared in the presence of EACA while controlling for age, suture phenotype, use of bone grafting, and length of surgery. Secondary outcomes measures included volume of crystalloid infused, length of hospital stay, and any postoperative intubation requirement. When analyzed based on length of surgery, EACA did reduce blood loss and blood transfusion (R 2 =0.19, P=.005 and R 2 =0.18, P=.010, respectively) with shorter surgeries. Using a standardized dosing regimen of EACA during craniosynostosis surgery, we found statistical significance in blood loss and transfusion requirements in surgeries of the shortest duration. We suspect this may be due to our selected dosing regimen, which may be lower than recently recommended. This study contributes to the growing body of evidence supporting EACA in CVR for craniosynostosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    What is following the impressive progress that has been made? During the last couple of years several tremors have shaken the field of Transfusion Medicine. The epicentres of those tremors were located on novel insights into the RBC storage lesion, on emerging connections between storage lesion and post-transfusion performance and effects, and on acknowledging that storage time is only one (rather than the most prominent) of the parameters which contribute to the progression of storage lesion in any given unit of blood. The optimisation of bio-preservation conditions emerged at the same time with all-new scientific knowledge gained by advances in research tools, implementation of technological innovations, and application of elegant in vitro and in vivo models of transfusion. Simultaneously, one after another, all the reported randomised clinical trials concluded, with spectacular consensus, that there is no significant difference in the rate of adverse clinical events (including death) among patients who underwent transfusion with fresh (and presumably good) or standard of care (and presumably bad) blood. The comparative analysis and comprehension of the aforementioned data would set the context for the next generation of research in blood transfusion science, since the need for safer and more efficient transfusions remains.

    Full Text Available Background and Objective : Hepatitis B and hepatitis C are significant health problems that might involve the late sequel of liver cirrhosis and hepatocellular carcinoma. A high prevalence of hepatitis B virus (HBV and hepatitis C virus (HCV in blood donors poses an increased risk of window period transmission through blood transfusion. The present study aimed to know the seroprevalence of hepatitis B virus (HBV and hepatitis C virus (HCV among blood donors in regional blood transfusion services of Nepal. Materials and Methods: This was a retrospective study conducted among blood donors in Banke (5,211, Morang (5,351, and Kaski (5,995 blood transfusion services. Serum samples were tested for hepatitis B surface antigen (HBsAg and anti-HCV antibodies using rapid enzyme immunoassays. The donors information was collected via the donor record register through their respective blood transfusion services. The software "Winpepi ver 3.8" was used for statistical analysis. Results: The seroprevalence rate of HBV was highest in the Banke (1.2% followed by Biratnagar (0.87% and Kaski (0.35% (P < 0.0001. The seroprevalence of HCV was highest in the Morang (0.26% followed by Kaski (0.16% and Banke (0.11% (P > 0.05. The seroprevalence of HBV was significantly higher than HCV in all three blood transfusion services. The burden of HBV as well as HCV seems to be higher in male donors (P > 0.05. Conclusion: The study revealed that the seroprevalence of HBV was alarmingly higher in two of the three blood transfusion services. Implementation of community-based preventive measures and improved strategies for safe blood supply might prove useful to decrease the seroprevalence.

    The relationship between perioperative blood transfusion and long-term survival after curative resection for hepatocellular carcinoma (HCC) remains controversial. The aim of the present study was to investigate the impact of blood transfusion on the long-term prognosis of HCC patients. Patients with primary HCC who underwent a curative hepatectomy from 2003 to 2011 were enrolled and then retrospectively studied. The clinicopathologic characteristics between patients in the blood transfusion and non-transfusion groups were matched using a propensity score matching (PSM) analysis. Univariate and multivariate Cox regression analyses were used to identify whether perioperative blood transfusion affects long-term survival after resection for HCC. A total of 374 patients were enrolled and 113 patients received perioperative transfusions. The 1-, 3- and 5-year disease-free and overall survival rates of the entire cohort were 65.0, 37.3 and 23.9%, and 90.9, 70.7 and 57.5%, respectively. The disease-free and overall survival rates of the blood transfusion group were significantly worse than the disease-free and overall survival rates of the non-transfusion group in the entire cohort (p blood transfusion was not an independent predictor of disease-free and overall survival in the propensity-matched cohort (p = 0.154, p = 0.667). The present study demonstrates that perioperative blood transfusion has no impact on disease-free and overall survival after curative resection for HCC.

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

    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.

    Allogenic blood transfusion (ABT) may be needed for severe bleeding during total pancreatectomy with autotransplantation (TPIAT), but may induce inflammation. This study investigated the impact of ABT. With a population of 83 patients who underwent TPIAT from 2006 to 2014, this study compared cytokine levels, patient characteristics, islet characteristics, metabolic outcomes, insulin requirements, and hemoglobin A1c for those who received a blood transfusion (BT) versus no blood transfusion (NBT). Initially, proinflammatory cytokines were moderately higher in the BT group than the NBT group. Despite longer procedures and more severe bleeding, the BT group had similar values to the NBT group for insulin requirements, serum C-peptide, hemoglobin A1c, and insulin independence rate. The probability of insulin independence was slightly higher in patients receiving ≥3 units of blood. ABT induced elevation of proinflammatory cytokines during the perioperative period in TPIAT, but these changes did not significantly change posttransplant islet function.

    The parasitic Chagas disease is caused by the protozoan Trypanosoma cruzi, which is mainly transmitted by insect vectors. Other infection routes, both in endemic and in nonendemic areas, include organ and marrow transplantation, congenital transmission, and blood transfusion. Asymptomatic chronic chagasic individuals may have a low and transient parasitemia in peripheral blood and, consequently, they can unknowingly transmit the disease via blood transfusion. Riboflavin and ultraviolet (UV) light pathogen reduction is a method to reduce pathogen transfusion transmission risk based on damage to the pathogen nucleic acids. In this study, we tested the effectiveness of this technology for the elimination of T. cruzi parasites in artificially contaminated whole blood units (WBUs) and thus for decreasing the risk of T. cruzi transfusion transmission. The contaminated WBUs were leukoreduced by filtration and treated with riboflavin and UV light. The level of pathogen reduction was quantified by a real-time polymerase chain reaction (qPCR) and a real-time reverse transcription-polymerase chain reaction (RT-qPCR) as a viability assay. The RNA (cDNA) quantification of the parasites showed a more than 99% reduction of viable T. cruzi parasites after leukoreduction and a complete reduction (100%) after the riboflavin and UV light treatment. Riboflavin and UV light treatment and leukoreduction used in conjunction appears to eliminate significant amounts of viable T. cruzi in whole blood. Both strategies could complement other blood bank measures already implemented to prevent the transmission of T. cruzi via blood transfusion. © 2017 AABB.

    We aimed to assess usefulness of the middle cerebral artery peak systolic velocity (MCA-PSV) in the prediction of fetal anemia after more than three intravenous fetal-exchange transfusions (IFET). A retrospective study was conducted over 6 years of 15 consecutive pregnancies with severe red blood cell fetomaternal alloimmunization requiring more than three IFETs. We evaluated correlation between MCA-PSV (expressed as multiples of the mean [MoM]) and pretransfusion hemoglobin (Hb) in the fetus (MoM). Analyses were also performed to assess the value of MCA-PSV to predict moderate to severe fetal anemia. Twenty-seven MCA-PSV measurements performed before the fourth to last IFET were coupled with pretransfusion Hb in the fetus. The median number of IFETs per fetus was five (range, four to eight). Five Hb samples found fetuses with severe (19%), seven with moderate (26%), and 15 with mild anemia (56%). There was a linear correlation between MCA-PSV(x) and Hb in the fetus(y): y = -0.21x + 0.93 (r = -0.50, p PSV with a threshold of 1.5 MoM was 75%, positive predictive value 73%, specificity 80%, sensibility 67%, and positive likelihood ratio 3.33. The area under the receiver operating characteristic curve was 0.78 (95% confidence interval, 0.59-0.96; p PSV with a threshold of 1.5 MoM had 94% negative predictive value, 80% sensibility, and a positive likelihood ratio of 2.5. This study shows that a correlation between MCA-PSV and Hb in the fetus persists even after more than three IFETs. MCA-PSV measurements thus remain useful to monitor fetuses at risk of anemia. © 2014 AABB.

    Full Text Available Objectives: The aim of this retrospective study is to identify intraoperative patient’s characteristics predicting the need for blood transfusion during CABG in our local cardiac surgical service. Methods: This study included 1835 consecutive patients, 1311 males and 524 females with mean age 58.8±9.9 years, undergoing coronary artery bypass grafting. Risk factors detected by univariate study were entered in a multivariate logistic regression model of the relationship between preoperative variables and blood transfusion. Results: Blood transfusion was used in 435 patients (29.9%. Univariate analysis identified hemoglobin, smoking, hypertension, sex, diabetes, BMI and use of cardiopulmonary bypass (CPB as significant predictors. Multivariate analysis revealed hemoglobin (OR: 0.8; CI: 0.74-0.86; P<0.001, CPB use (OR: 12.2; CI: 8.2-18.1; P<0.001 and female gender (OR: 2.29; CI:1.72-3.04; P<0.001 as independent risk factors for blood transfusion. Conclusions: The predictors of RBC transfusion after isolated CABG were performing CPB, preoperative hemoglobin and female gender. These factors can be used as a clinical tool to preserve blood bank resources without increasing patient’s risk.

    Previous studies have evaluated the efficacy of preoperative acute normovolemic hemodilution (PANH) in reducing the need for allogeneic blood transfusion. However, the results to date have been controversial. In this study, we sought to reassess the efficacy and safety of PANH based on newly emerging evidence. Medline, EMBASE, ISI Web of Knowledge, and Cochrane Central Register of Controlled Trials databases were searched using the key words "hemodilution," "autotransfusion," or "hemorrhage" to retrieve all randomized controlled trials examining the benefits of PANH compared with control patients not undergoing PANH in any type of surgery. Sixty-three studies involving 3819 patients were identified. The risk of requiring an allogeneic blood transfusion and the overall volume of allogeneic red blood cell transfused during the perioperative period were reduced in the PANH group compared with the control group (relative risk, 0.74; 95% confidence interval, 0.63 to 0.88; P = 0.0006; weighted mean difference, -0.94 units; 95% confidence interval, -1.27 to -0.61 units; P transfusion. Perioperative blood loss, adverse events, and the length of hospitalization were comparable between these groups. Although these results suggest that PANH is effective in reducing allogeneic blood transfusion, we identified significant heterogeneity and publication bias, which raises concerns about the true efficacy of PANH.

Excessively aggressive transfusion practices may be driven by mandatory physician notification of critical hemoglobin values that do not generally require transfusion. We examined the effect of decreasing the critical value of hemoglobin from 8 to 7 g/dL at our institution. Along with this change, mandatory provider notification for readings between 7 and 8 g/dL was rescinded. Transfusion rates were compared retrospectively during paired 5-month periods for patients presenting in three key hemoglobin ranges (6.00–6.99, 7.00–7.99, and 8.00–8.99 g/dL. A change in transfusion practices was hypothesized in the 7–8 g/dL range, which was no longer labeled critical and for which mandated physician calls were rescinded. Transfusion rates showed a statistically significant 8% decrease (P≤0.0001 during the 5-month period post change in our transfusion practices. This decrease in the 7.00–7.99 g/dL range was significantly greater than the 2% decrease observed in either the 6–6.99 g/dL (P=0.0017 or 8–8.99 g/dL (P≤0.0001 range. Cost savings of up to $700,000/year were extrapolated from our results showing 491 fewer units of red blood cells transfused during the 5-month post change. These cost

    Transfusion of blood at the limits of approved storage time is associated with lower red blood cell (RBC) post-transfusion recovery and hemolysis, which increases plasma cell-free hemoglobin and iron, proposed to induce endothelial dysfunction and impair host defense. There is noted variability among donors in the intrinsic rate of storage changes and RBC post-transfusion recovery, yet genetic determinants that modulate this process are unclear. We explore RBC storage stability and post-transfusion recovery in murine models of allogeneic and xenogeneic transfusion using blood from humanized transgenic sickle cell hemizygous mice (Hbatm1PazHbbtm1TowTg(HBA-HBBs)41Paz/J) and human donors with a common genetic mutation sickle cell trait (HbAS). Human and transgenic HbAS RBCs demonstrate accelerated storage time-dependent hemolysis and reduced post-transfusion recovery in mice. The rapid post-transfusion clearance of stored HbAS RBC is unrelated to macrophage-mediated uptake or intravascular hemolysis, but by enhanced sequestration in the spleen, kidney and liver. HbAS RBCs are intrinsically different from HbAA RBCs, with reduced membrane deformability as cells age in cold storage, leading to accelerated clearance of transfused HbAS RBCs by entrapment in organ microcirculation. The common genetic variant HbAS enhances RBC storage dysfunction and raises provocative questions about the use of HbAS RBCs at the limits of approved storage.

    The occurrence of transfusion transmissions of variant Creutzfeldt-Jakob disease (CJD) cases has reawakened attention to the possible similar risk posed by other forms of CJD. CJD with a definite or probable diagnosis (sporadic CJD, n = 741; genetic CJD, n = 175) and no-CJD patients with definite alternative diagnosis (n = 482) with available blood transfusion history were included in the study. The risk of exposure to blood transfusion occurring more than 10 years before disease onset and for some possible confounding factors was evaluated by calculating crude odds ratios (ORs). Variables with significant ORs in univariate analyses were included in multivariate logistic regression analyses. In the univariate model, blood transfusion occurring more than 10 years before clinical onset is 4.1-fold more frequent in sporadic CJD than in other neurologic disorders. This significance is lost when the 10-year lag time was not considered. Multivariate analyses show that the risk of developing sporadic CJD after transfusion increases (OR, 5.05) after adjusting for possible confounding factors. Analysis conducted on patients with genetic CJD did not reveal any significant risk factor associated with transfusion. This is the first case-control study showing a significant risk of transfusion occurring more than 10 years before clinical onset in sporadic CJD patients. It remains questionable whether the significance of these data is biologically plausible or the consequence of biases in the design of the study, but they counterbalance previous epidemiologic negative reports that might have overestimated the assessment of blood safety in sporadic CJD. © 2010 American Association of Blood Banks.

    To describe the perioperative blood conservation strategies and postoperative outcomes in patients who undergo complex spinal surgery for tumor resection and who also refuse blood product transfusion. A retrospective case series. A single-center, tertiary care and academic teaching hospital in Canada. All adult patients undergoing elective major spine tumor resection and refusing blood product transfusion who were referred to our institutional Blood Utilization Program between June 1, 2004, and May 9, 2014. Data on the use of iron, erythropoietin, preoperative autologous blood donation, acute normovolemic hemodilution, antifibrinolytic therapy, cell salvage, intraoperative hypotension, and active warming techniques were collected. Data on perioperative hemoglobin nadir, adverse outcomes, and hospital length of stay were also collected. Four patients who refused blood transfusion (self-identified as Jehovah's Witnesses) underwent non-emergent complex spine surgery for recurrent chondrosarcoma, meningioma, metastatic adenocarcinoma, and metastatic malignant melanoma. All patients received 1 or more perioperative blood conservation strategy including preoperative iron and/or erythropoietin, intraoperative antifibrinolytic therapy, and cell salvage. No patients experienced severe perioperative anemia (average hemoglobin nadir, 124 g/L) or anemia-related postoperative complications. Patients who decline blood product transfusion can successfully undergo major spine tumor resection. Careful patient selection and timely referral for perioperative optimization such that the risk of severe anemia is minimized are important for success. Copyright © 2016 Elsevier Inc.

    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.

    As transfusion in the elderly patients has increased over the last decades, and with the aim of improving blood policy, post-transfusion red blood cell alloimmunisation, a delayed serological transfusion reaction, was investigated in patients 80 years old or over. For every adverse reaction to a transfusion, a report is sent to the French haemovigilance database. All cases of red blood cell alloimmunisation reported in the haemovigilance database were collected, and an analysis was performed on those cases in transfused patients 80 years old or over. There were 11,625 reports of red blood cell alloimmunisation from 1 January, 2008 to 31 December, 2013, of which 3,617 (31.1%) occurred in patients 80 years old or over. Among this subgroup, red blood cell concentrates were the most frequently involved blood component (3,482 reports, 96.3%). Red blood cell alloimmunisation after transfusion of platelet concentrates was also notified (132 reports, 3.7%). Anti-KEL1 was the most frequent antibody (874 reports, 24.2%). The imputability of the blood component was certain in 2,340 cases (64.7%) and probable in 1,078 (29.8%). In 2013, the incidence of red blood cell alloimmunisation was 4.14 per 1,000 transfused patients aged 80 years old or over. In a 6-year national survey in which 40,570 reports were made, there were 3,617 cases of red blood cell alloimmunisation in transfused recipients of 80 years old or over. This delayed serological transfusion reaction is not rare. Red blood cell concentrates were predominantly involved, but cases caused by platelet concentrates were also described. In order to prevent alloimmunisation in the elderly, several factors must be evaluated before transfusing matched red blood cell concentrates: the patient's age, pathology and its outcome, the type of transfusion support (chronic or not), life expectancy, and blood product availability.

    Total hip and knee arthroplasty (THA and TKA) are associated with significant blood loss and some patients require postoperative blood transfusion. While tranexamic acid has been studied extensively among this population, we tested the hypothesis that epsilon aminocaproic acid (EACA) can reduce blood loss and transfusion after joint arthroplasty. In April 2014, our Veterans Affairs Medical Center introduced a protocol to administer EACA during THA and TKA. No antifibrinolytics were used previously. We retrospectively compared blood loss and incidence of transfusion among patients who underwent primary arthroplasty in the year before standardized administration of EACA with patients having the same procedures the following year. Blood loss was measured as delta hemoglobin (preoperative hemoglobin - hemoglobin on postoperative day 1). All patients undergoing primary THA or TKA were included. Patients having revision surgery were excluded. We identified 185 primary arthroplasty patients from the year before and 184 from the year after introducing the EACA protocol. There were no changes in surgical technique or attending surgeons during this period. Delta hemoglobin was significantly lower in the EACA group (2.7 ± 0.8 mg/dL) compared to the control group (3.4 ± 1.1 mg/dL) (P < .0001). The incidence of blood transfusion was also significantly lower in the EACA group (2.7%) compared to the control group (25.4%) (P < .0001). There was no difference in venous thromboembolic complications between groups. We demonstrated reductions in hemoglobin loss and transfusion following introduction of the EACA protocol in patients undergoing primary arthroplasty. EACA offers a lower cost alternative to TXA for reducing blood loss and transfusion in this population. Published by Elsevier Inc.

    Transfusion of red blood cells is a very common inpatient procedure, with more than 1 in 70 people in the USA receiving a red blood cell transfusion annually. However, stored red blood cells are a non-uniform product, based upon donor-to-donor variation in red blood cell storage biology. While thousands of biological parameters change in red blood cells over storage, it has remained unclear which changes correlate with function of the red blood cells, as opposed to being co-incidental changes. In the current report, a murine model of red blood cell storage/transfusion is applied across 13 genetically distinct mouse strains and combined with high resolution metabolomics to identify metabolic changes that correlated with red blood cell circulation post storage. Oxidation in general, and peroxidation of lipids in particular, emerged as changes that correlated with extreme statistical significance, including generation of dicarboxylic acids and monohydroxy fatty acids. In addition, differences in anti-oxidant pathways known to regulate oxidative stress on lipid membranes were identified. Finally, metabolites were identified that differed at the time the blood was harvested, and predict how the red blood cells perform after storage, allowing the potential to screen donors at time of collection. Together, these findings map out a new landscape in understanding metabolic changes during red blood cell storage as they relate to red blood cell circulation. Copyright© Ferrata Storti Foundation.

    The recent establishment of the National Healthcare Safety Network Hemovigilance Module in the United States affords an opportunity to compare results with those of other developed nations. Using data from national haemovigilance systems, reactions associated with red blood cell (RBC) transfusion and residual risks of transfusion-transmitted infectious diseases were assembled from 17 nations. Country-specific rates of adverse events were pooled using random-effects Poisson regression. Febrile non-haemolytic and delayed serologic transfusion reactions were the most frequent adverse events reported after RBC transfusion, occurring in 26 patients per 100 000 RBC units and 25 patients per 100 000 RBC units administered, respectively. Rates of allergic, febrile non-haemolytic and delayed haemolytic transfusion reactions in the United States were significantly greater than the pooled rates from other countries. Frequencies of adverse events generated from the national haemovigilance programme in the United States were considerably lower than when obtained through active surveillance. Haemovigilance reports of adverse events in the United States are comparable to, or greater than, reports from other developed countries. Rates generated from haemovigilance programmes are lower than those obtained through active surveillance. The lack of universal leucoreduction of RBC units may be a contributing factor to the higher rate of some adverse events in the United States. © 2015 International Society of Blood Transfusion.

    While the transfusion-transmission (TT) risk associated with the major transfusion-relevant viruses such as HIV is now very low, during the last 20 years there has been a growing awareness of the threat to blood safety from emerging infectious diseases, a number of which are known to be, or are potentially, transfusion transmissible. Two published models for estimating the transfusion-transmission risk from EIDs, referred to as the Biggerstaff-Petersen model and the European Upfront Risk Assessment Tool (EUFRAT), respectively, have been applied to several EIDs in outbreak situations. We describe and compare the methodological principles of both models, highlighting their similarities and differences. We also discuss the appropriateness of comparing results from the two models. Quantitating the TT risk of EIDs can inform decisions about risk mitigation strategies and their cost-effectiveness. Finally, we present a qualitative risk assessment for Zika virus (ZIKV), an EID agent that has caused several outbreaks since 2007. In the latest and largest ever outbreak, several probable cases of transfusion-transmission ZIKV have been reported, indicating that it is transfusion-transmissible and therefore a risk to blood safety. We discuss why quantitative modeling the TT risk of ZIKV is currently problematic. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

    Full Text Available Objectives: It is quite common to have advanced cancer or end-stage renal disease patients for regular or even frequent blood transfusion in palliative care. However, due to geographical reason in some hospice centers, blood transfusion is sometimes difficult if blood bank is closed during non-office hour or not available. Methods: Here, we reported a new blood releasing system, that is, remote blood releasing system, that could be used safely by nursing staff alone when the blood bank was closed during the night time and holiday. Results: On-call nursing staff could collect red cells successful in these two cases. Conclusion: The new blood releasing system seems useful. However, larger sample sizes and longer period of study are required to estimate its efficacy and safety. The provision of antibody-positive red cells and platelet remained a limitation of this system.

    The purpose of this report is to analyze the cause of allergic transfusion reaction. The methods of immunoblot and immunonephelometry were applied to detect the levels of the immunoglobulins of IgA (Immunoglobulin A) and IgE (Immunoglobulin E) and the level of sIgE (specific Immunoglobulin E) to shrimp allergen both in the patient's pre and post transfusion blood samples, respectively. After transfusion, The level of sIgE to shrimp showed "increase" corresponding to the concentration of 0.70-3.5 IU/ml. The allergic transfusion reaction was very likely caused by passive transfer of shrimp antigen to the patient allergic to shrimp. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Elmer L. DeGowin, MD, like many of the pioneers of American blood banking and transfusion medicine, entered the discipline because of scientific curiosity and a desire to provide efficacious and safe allogeneic transfusions to patients. Much of the early impetus and financial support were fueled by the military needs of World War II. Dr. DeGowin and his colleagues provided important information pertaining to the preservation, storage, transportation, and transfusion of blood. After the war, many of these investigations continued and were applied to civilian practices. The legacy of Dr. DeGowin to provide exemplary service, teaching, and research has been sustained by the physicians and staff of the Elmer L. DeGowin Memorial Blood Center (University of Iowa Hospitals and Clinics, Iowa City, Ia).

    The value of prehospital red blood cell (RBC) transfusion for trauma patients is controversial. The purposes of this literature review were to determine the mortality rate of trauma patients with hemodynamic instability and the benefit of prehospital RBC transfusion. A 30-year systematic literature review was performed in 2016. Eligible studies were combined for meta-analysis when tests for heterogeneity were insignificant. The synthesized mortality was 35.6% for systolic blood pressure ≤ 90 mmHg; 51.1% for ≤ 80 mmHg; and 63.9% for ≤ 70 mmHg. For patients with either hypotension or emergency trauma center transfused RBCs, the synthesized Injury Severity Score (ISS) was 27.0 and mortality was 36.2%; the ISS and mortality correlation was r = 0.766 (P = 0.0096). For civilian patients receiving prehospital RBC transfusions, the synthesized ISS was 27.5 and mortality was 39.5%. One civilian study suggested a decrement in mortality with prehospital RBC transfusion; however, patient recruitment was only one per center per year and mortality was prehospital RBC transfusion and a matched control subset showed that the synthesized mortality was similar for those transfused (37.5%) and not transfused (38.7%; P = 0.8933). A study of civilian helicopter patients demonstrated a similar 30-day mortality for those with and without prehospital blood product availability (22% versus 21%; P = 0.626). Mortality in a study of matched military patients was better for those receiving prehospital blood or plasma (8%) than the controls (20%; P = 0.013). However, transfused patients had a shorter prehospital time, more advanced airway procedures, and higher hospital RBC transfusion (P 16 showed similar mortality with and without prehospital RBC availability (27.6% versus 32.0%; P = 0.343). Trauma patient mortality increases with the magnitude of hemodynamic instability and anatomic injury. Some literature evidence indicates no survival advantage with prehospital RBC availability

    Transfusion of ABO-incompatible platelets (PLTs) is associated with reduced PLT recovery and a risk of transfusion reactions. However, a policy of transfusing only ABO-identical PLTs may increase wastage due to product outdating. A prospective study attempting to compare the effects of different ABO compatibility strategies could be costly and disruptive to a blood bank's operations. We designed a "virtual blood bank," a stochastic computer program that models the stocking and release of products to meet demand for PLT transfusion in a simulated hospital population. ABO-nonidentical transfusions (ABOni), outdates, and inventory shortages were recorded and compared under two different transfusion strategies: ABO-First, a strategy that prioritizes transfusion of ABO-identical PLTs, and Age-First, a strategy that minimizes outdating by transfusing products closest to expiration. The ABO-First strategy resulted in fewer ABOni but more outdates than the Age-First strategy. Under conditions that mimic a large hospital blood bank, the ABO-First strategy was more cost-effective overall than the Age-First strategy if avoiding an ABOni is valued at more than $19 to $26. For a small blood bank, the ABO-First strategy was more cost-effective if avoiding an ABOni is valued at more than $104 to $123. Based on a virtual blood bank computer simulation, the cost of avoiding an ABOni using the ABO-First strategy varies greatly by size of institution. Individual blood banks must carefully consider these management strategies to determine the most cost-effective solution. © 2014 AABB.

    Juvenile angiofibroma is a benign, non-encapsulated neoplasm, consisting of vascular and connective tissue. Its main feature is a local malignancy. In its clinical course it destroys adjoining structures, without metastasizing. It appears rarely, and is mainly found in boys at puberty. Among theories about the aetiology of juvenile angiofibroma, we must consider a haematoma-like lesion, an angioma with an extended fibrous component, or type of inflammatory allergic polyp. In the development of the lesion the participation of hormonal disorders on the pituitary gland-gonad axis is also suggested. According to the latest research, juvenile angiofibroma is regarded as a developmental defect, affecting the embryonic vascular network surrounding the sphenoid bone. If the patient or his/her parents refuse blood transfusion and use of blood products, it is necessary to apply modifications in the routine perioperative treatment. In the case of the patient refusing blood and blood products transfusion because of their beliefs, it is possible to get consent to use different, highly processed products like albumins or a cryoprecipitate, as well as applying some blood-saving techniques. 1. Removal of juvenile angiofibroma with minimal bleeding is possible. 2. Applying erythropoietin and iron preparations prior to surgery increases erythropoiesis and reduces the risks in transfusion. 3. Applying intraoperative normovolaemic haemodilution is a safe method and allows avoidance of transfusion of blood-derived products.

  14. A Case of Vertical Transmission of Chagas Disease Contracted via Blood Transfusion in Canada

    Full Text Available Chagas disease is caused by the protozoan parasite Trypanosoma cruzi and is endemic in many countries in Latin America, where infected bugs of the Triatominea subfamily carry the parasite in the gut and transmit it to humans through fecal contamination of a bite. However, vertical transmission and transmission through blood transfusion and organ transplantation is well documented. Increasing immigration from endemic countries to North America has prompted blood operators, including Canadian Blood Services and Hema Quebec, to initiate blood donor testing for Chagas antibody. In the present report, an unusual case of vertical transmission from a mother, most likely infected through blood transfusion, and detected as part of a concurrent seroprevalence study in blood donors is described.

    Selective serotonin reuptake inhibitors (SSRIs) and other psychotropics are receiving increasing attention due to reports on inhibition of thrombocyte function and an increased bleeding risk in surgical settings. Studies in total hip and total knee arthroplasty (THA and TKA, respectively) have shown conflicting results, questioning whether the potential increased bleeding risk is of clinical importance. Prospective consecutive collection of data on preoperative comorbidity in patients undergoing primary unilateral THA or TKA was cross-referenced with regional transfusion databases and The Danish National Database of Reimbursed Prescriptions for information regarding blood transfusions and psychopharmacologic treatment. All participating orthopedic centers followed similar perioperative guidelines. Multiple logistic regression analysis was applied to calculate odds ratios (ORs) for transfusion between preoperative users and nonusers of psychotropics. Of 8402 patients, 569 (6.8%) were SSRI users versus 7833 (93.2%) nonusers. A total of 109 (19,2%) patients in the SSRI group and 700 (8.9%) in the "no-SSRI" group received blood intra- or postoperatively. Preoperative SSRI treatment was a risk factor for perioperative transfusion (OR, 1.98; 95% confidence interval [CI], 1.44-2.70). Other antidepressants (OAs) were associated with an increased risk of transfusion (OR, 1.69; 95% CI, 1.17-2.44) as well as the combination of SSRIs and OAs (OR, 3.31; 95% CI, 1.79-6.13). Singular use of antipsychotics (APs) increased the transfusion risk (OR, 2.37; 95% CI, 1.04-2.41), while AP medicine in combination with antidepressants did not. Preoperative treatment with SSRIs, OAs, or APs are independent risk factors for blood transfusion in elective fast-track THA and TKA. © 2017 AABB.

    Blood transfusion is a critical and multi-step process that can be lifesaving. At the same time, any mistakes can be life threatening. An electronic blood transfusion system has been designed to ensure the correctness and safety of the blood transfusion process. The standards for the system include notification mechanisms to inform system managers of any errors in the process. Analysis of system alerts has been used to evaluate the performance of the system. The majority of alerts were classified as 'moderate' in terms of risk (i.e. operational rather than affecting clinical safety) and tended to result from user error. The process of alert acknowledgement and resolution by the system administrator acted as a bottleneck whenever the alerts increased above 100 items per month. Although there was no statistically significant correlation between the number of alerts and the number of transfusions or number of the new users of the system, relatively similar patterns were observable in their charts. A major benefit is that the alerts automatically provided information that would not be captured in a manual transfusion process.

    The expected cost-explosion in transfusion medicine (increasing imbalance between donors and recipients, treatment of transfusion-associated complications) increases the socio-economic significance of the development of safe and effective synthetic oxygen carriers as an alternative to the transfusion of allogeneic red blood cells. Currently two types of artificial oxygen carriers have been tested for safety and efficacy in cases of severe anemia otherwise requiring transfusion. Solutions based on human or bovine hemoglobin (HBOC) possess vasoconstrictor properties in addition to their oxygen transport capacity. The impact of vasoconstriction on tissue perfusion and organ function is however not yet fully understood. Nevertheless, in 2001 the bovine HBOC Hemopure was approved in South Africa for treatment of acutely anemic surgical patients. The purely synthetic perfluorocarbon (PFC) emulsions increase the physically dissolved portion of arterial oxygen content. Due to their particulate nature (emulsion droplets) PFCs may only be infused in low doses to avoid overload and malfunction of phagocytic cells of the reticulo-endothelial system. As part of a multimodal blood conservation program (including normovolemic hemodilution and hyperoxia) the low-dose administration of Oxygent effectively increases intraoperative anemia tolerance. Although reduction of perioperative allogeneic blood transfusion has already been demonstrated for HBOC and PFC, the global clinical establishment of artificial oxygen carriers is not to be expected in the near future.

    Full Text Available Abstract Background Cardiac surgery is a major consumer of blood products, and hemodilution increases transfusion requirements during cardiac surgery under CPB. As intraoperative parenteral fluids contribute to hemodilution, we evaluated the hypothesis that intraoperative fluid restriction reduces packed red-cell (PRC use, especially in transfusion-prone adults undergoing elective cardiac surgery. Methods 192 patients were randomly assigned to restrictive (group A, 100 pts, or liberal (group B, 92 pts intraoperative intravenous fluid administration. All operations were conducted by the same team (same surgeon and perfusionist. After anesthesia induction, intravenous fluids were turned off in Group A (fluid restriction patients, who only received fluids if directed by protocol. In contrast, intravenous fluid administration was unrestricted in group B. Transfusion decisions were made by the attending anesthesiologist, based on identical transfusion guidelines for both groups. Results 137 of 192 patients received 289 PRC units in total. Age, sex, weight, height, BMI, BSA, LVEF, CPB duration and surgery duration did not differ between groups. Fluid balance was less positive in Group A. Fewer group A patients (62/100 required transfusion compared to group B (75/92, p Conclusions Our data suggest that fluid restriction reduces intraoperative PRC transfusions without significantly increasing postoperative transfusions in cardiac surgery; this effect is more pronounced in transfusion-prone patients.

  19. Transfusion practices in trauma

    2014-01-01

    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.

    Prehospital transfusions are a novel yet increasingly accepted intervention in the adult population as part of remote damage control resuscitation, but prehospital transfusions remain controversial in children. Our purpose was to review our pediatric prehospital transfusion experience over 12 years to describe the safety of prehospital transfusion in appropriately triaged trauma and nontrauma patients. Children (prehospital transfusions of blood products were safe in this small group of appropriately triaged pediatric patients. Further studies are needed to determine if outcomes are improved and to devise a rigorous protocol for this prehospital intervention for critically ill pediatric patients.

    The diagnosis of disseminated intravascular coagulation (DIC) in obstetrics is complicated owing to physiological changes, particularly during late pregnancy and the postpartum period. Therefore, a pregnancy-modified DIC score that includes only three components of the International Society on Thrombosis and Hemostasis (ISTH) DIC score has been constructed. Our aim was to determine how many blood-transfused postpartum women actually had the diagnosis of overt DIC according to the modified ISTH score and had the correct indications for blood transfusion. We retrospectively analyzed 279 women who had received transfusion of at least two units of blood for postpartum hemorrhage. We used the modified ISTH score for DIC, which is based on platelet count, fibrinogen concentration, and prothrombin time (PT) differences. A total score of 26 points or higher indicated overt DIC, whereas a score lower than 26 points represented nonovert DIC. According to the modified ISTH score, 100 of the 279 patients (35.8%) had overt DIC, with a median DIC score of 37.0. Thirty-five percent of patients in the overt DIC group and 25.7% in the nonovert DIC group had received more than four units of blood. The levels of PT and activated partial thromboplastin time were higher, and the fibrinogen level was lower in patients with overt DIC. According to the modified ISTH score, we found that blood transfusion was unnecessary in 179 of the 279 postpartum women (64.1%). If this scoring system is used to determine which patients should be transfused, unnecessary transfusions and their related risks and complications will be prevented.

    A timely risk assessment is desired to guide decisions on preventive transfusion safety measures during emerging infectious disease (EID) outbreaks. The European Up-Front Risk Assessment Tool (EUFRAT) model was developed to provide quantitative transmission risk estimates of EIDs through blood transfusion. The generic model comprises five sequential steps to estimate the infection risks in the blood transfusion chain: 1) the prevalence of infection in the donor population, 2) the risk of obtaining infected donations, 3) infected components, 4) infected blood products, and 5) the risk of transmitting the infection to recipients. The model uses inputs from epidemiologic characteristics of an EID and transfusion practice. The model was applied to data from a recent chikungunya outbreak in Italy. Based on data from the outbreak peak, an estimated prevalence of 1.07 (95% confidence interval [CI], 0.38-2.03) per 100,000 donors would lead to 0.04 infected donations (95% CI, 0.01-0.10), 0.13 infected blood components, 0.13 infected end products, and 0.0001 severe infections in recipients. This estimated risk can be reduced by increasing the duration of quarantine of the donated blood and becomes zero after 7 or more days of quarantine. The model also estimated the probability of a donor returning from the outbreak area and subsequently donating infected blood in his home country to be 0.30 (95% CI, 0.01-0.65) per 100,000. The model can be used to quantify EID outbreak risks to blood transfusion recipients and the effect of targeted safety interventions and as such support public health decision-making. © 2012 American Association of Blood Banks.

    Despite a century of research focused on the development and implementation of effective control strategies, infection with the malaria parasite continues to result in significant morbidity and mortality worldwide. An effective malaria vaccine is considered by many to be the definitive solution. Yet, after decades of research, we are still without a vaccine that is capable of inducing robust, long lasting protection in naturally exposed individuals. Extensive sub-unit vaccine development focused on the blood stage of the malaria parasite has thus far yielded disappointing results. There is now a renewed focus on whole parasite vaccine strategies, particularly as they may overcome some of the inherent weaknesses deemed to be associated with the sub-unit approach. This review discusses the whole parasite vaccine strategy focusing on the blood stage of the malaria parasite, with an emphasis on recent advances and challenges in the development of killed and live attenuated vaccines.

    Evidence to support many blood transfusion policies and practices in sub-Saharan Africa (SSA) is weak or lacking. SSA cannot extrapolate from wealthy countries’ research findings because its environment, users and structures are very different and SSA has critical blood shortages.

    2017-01-01

    Acute anemia is associated with both cerebral dysfunction and acute kidney injury and is often treated with red blood cell transfusion. We sought to determine if blood transfusion changed the cerebral oximetry entropy, a measure of the complexity or irregularity of the oximetry values, and if this change was associated with subsequent acute kidney injury. This was a retrospective, case-control study of patients undergoing cardiac surgery with cardiopulmonary bypass at a tertiary care hospital, comparing those who received a red blood cell transfusion to those who did not. Acute kidney injury was defined as a perioperative increase in serum creatinine by ⩾26.4 μmol/L or by ⩾50% increase. Entropy was measured using approximate entropy, sample entropy, forbidden word entropy and basescale4 entropy in 500-point sets. Forty-four transfused patients were matched to 88 randomly selected non-transfused patients. All measures of entropy had small changes in the transfused group, but increased in the non-transfused group (pentropy (odds ratio = 1.609, 95% confidence interval = 1.057-2.450, p = 0.027) and the interaction between basescale entropy and transfusion were significantly associated with subsequent development of acute kidney injury. The transfusion of red blood cells was associated with a smaller rise in entropy values compared to non-transfused patients, suggesting a change in the regulation of cerebral oxygenation, and these changes in cerebral oxygenation are also associated with acute kidney injury.
