Pediatric patient safety in the administration of blood components / Seguridad de pacientes pediátricos al administrar hemocomponentes / Segurança do paciente pediátrico na administração de hemocomponentes

ABSTRACT Objective: to analyze pediatric patient safety in the administration of blood components. Method: a documentary and retrospective study, developed at a hospital in the Brazilian Midwest region. Data collection took place through medical records and 234 transfusions were identified, performed in 90 patients aged from zero to twelve years old, hospitalized between July and December 2020. An instrument based on good practice guidelines about blood components was used. Descriptive and inferential statistics were used for data analysis. Results: the transfusions were predominantly performed in breastfeeding infants (71.1%). Blood transfusions in critical sectors stood out (86.3%), as well as with indication of a clinical order (87.2%) and prescription of packed red blood cells (75.3%). The Nursing reports identified adverse events (n=05) and incidents (n=13) that were associated with inadequacies between the prescribed and infused volumes and the request and administration time (p<0.001), although no notification was formalized in the institution during the period. Conclusion: the administration of blood components presented nonconformities, which results in risk situations for pediatric patients.

Uso de componentes sanguíneos en el Hospital Docente Provincial Oncológico María Curie en Camagüey / Use of blood components at the Oncologica l University Hospital Marie Curie of Camagüey

Introducción: La comunidad médica en muchas partes del mundo está preocupada porque se indica realizar más transfusiones que lo recomendado. La transfusión de sangre alogénica se ha considerado erróneamente un procedimiento exento de peligros y con beneficios indiscutibles; además, no es una forma totalmente segura para tratar la anemia asociada al cáncer. Objetivo: Analizar el consumo de componentes sanguíneos en el Hospital Docente Provincial Oncológico María Curie en Camagüey. Métodos: Estudio descriptivo, longitudinal, retrospectivo, sustentado en el análisis del consumo hospitalario de componentes sanguíneos en el período enero 2018 a diciembre 2021. Las variables analizadas fueron: cantidad mensual de unidades transfundidas de componentes sanguíneos, celulares y plasmáticos; el total de pacientes ingresados y transfundidos y la tasa de hemoterapia por cada 1000 ingresos hospitalarios. Resultados: El concentrado de eritrocitos fue el componente sanguíneo más solicitado en el período desde 2018 hasta 2021 (excepto en tres meses). La tasa de hemoterapia se mantuvo por encima de 245 hemocomponentes transfundidos por cada 1000 pacientes ingresados. Conclusiones: El consumo de hemocomponentes, según el cumplimiento de la tasa de hemoterapia, fue evaluado de mal en los años desde 2018 hasta 2021. Se sugiere mejorar la seguridad del paciente y la calidad de la asistencia médica con la aplicación imprescindible del método clínico, la preparación en medicina transfusional, el establecimiento de los consensos de criterios que sirvan de guía para el tratamiento de la anemia asociada a cáncer y la atención centrada en el paciente (tratamientos personalizados).

Introduction: Around the world, the Medical Community concerned with blood transfusions being recommended more than it is indicated. Allogenic blood transfusions have been erroneously considered as a safe procedure with unquestionable benefits; as well as it is not completely safe for cancer anemia treatment. Objective: To analyse the use of blood components at the Oncological Hospital Marie Curie of Camagüey Method: Longitudinal, descriptive study, retrospectively sustained in the analysis of the consumption of blood components at the hospital from January 2018 to December 2021. Analysed variables were the monthly quantity of transfused units, cellular and plasma, blood products, total of admitted patients, total transfused patients and haemotherapy rate for each 1000 patients admitted at the hospital. Results: Red blood cells were the most requested components during the study period. From 2018 to 2021 (except three months). Haemotherapy rate stayed above 245 blood component transfused by each 1000 admitted patients. Conclusions: According to compliance with the haemotherapy rate, the use of blood components was evaluated unfavorably in analyzed period. With the indispensable application of the clinical method, education in transfusion medical practice, the consensus criteria as a guide for anemia cancer treatment, and patient-centered attention (personalized treatments), will improve the patient's safety and the quality of the medical treatment.

Puesta al día sobre transfusión masiva / Massive transfusion update / Atualização sobre transfusão maciça

La transfusión masiva plantea desafíos clínicos, organizacionales y logísticos para el personal de la salud en general y los servicios de Medicina Transfusional en particular. No existe una definición universalmente aceptada de transfusión masiva, las definiciones más comúnmente utilizadas se basan en el número de unidades de sangre administradas dentro de un cierto período de tiempo. La mayoría de los eventos de transfusión masiva ocurren en el contexto de hemorragias graves en pacientes quirúrgicos, politraumatizados, con hemorragia gastrointestinal u obstétrica. La reanimación de control de daños y los protocolos de transfusión masiva son las estrategias más utilizadas actualmente para el tratamiento inicial, seguidas de un tratamiento personalizado, dirigido por objetivos, mediante la monitorización de la coagulación en tiempo real mediante estudios viscoelásticos. Existen una serie de controversias alrededor del tratamiento óptimo, incluyendo el uso de sangre total, la relación de hemocomponentes a utilizar, el uso de concentrados de factores de la coagulación, y la indicación óptima del ácido tranexámico. El estudio de los productos ideales para el tratamiento de los pacientes con sangrado masivo se ha convertido en un área de gran interés de la investigación científica. El contexto clínico en el que ocurrió el evento hemorrágico, el número de hemocomponentes transfundidos, la edad del paciente y las comorbilidades son los predictores más importantes de la sobrevida a corto y largo plazo. Esta revisión narrativa explora el estado actual del conocimiento sobre la transfusión masiva, así como los avances que podemos esperar en el futuro cercano.

Massive transfusion poses clinical, organizational and logistic challenges for the health staff in general, and the Transfusion Medicine Services in particular. There is no universally accepted definition for massive transfusion, the most widely used being based on the number of blood units administered in a certain period of time. Most massive transfusion events occur in the context of severe hemorrhage on surgical or multiple-trauma patients or patients with gastrointestinal or obstetric bleeding. Today, damage control resuscitation and massive transfusion protocols are the most common strategies for initial treatment, followed by personalized therapy, goal-directed, my means of monitoring coagulation in real time with viscoelastic studies. There are disputes as to the best surgical treatment, including using whole blood, the relation of blood components to be used, the use of coagulation factor concentrates and the optimal indication of tranexamic acid. The study of ideal products to treat patients with massive hemorrhage has become an area of great interest for scientific research. The clinical context of the hemorrhagic event, the number of blood components transfused, patient's age and comorbilities are the most important predictors for survival in the short and long term. This narrative review explores the current state of affairs on knowledge about massive transfusion, as well as progress to be expected in the near future.

Incidence of adverse transfusion reactions in Chinese children: a meta-analysis / 中国输血杂志

【Objective】 To systematically evaluate the incidence of adverse transfusion reactions in Chinese children, so as to provide scientific basis for prevention and early intervention. 【Methods】 Literature databases such as PubMed, EMbase, The Cochrane Library, CNKI, Wanfang and VIP were searched in terms of the incidence of adverse transfusion reactions in Chinese children from January 2000 to December 2022. Two researchers extracted literature data independently according to the inclusion and exclusion criteria and conducted quality evaluation of included studies according to AHRQ quality evaluation scale. Statistical analysis was performed using Stata 14.0 software. 【Results】 A total of 870 literatures were retrieved, and 13 were included in the study, with a total of 181 274 cases with blood transfusion. Meta-analysis showed that the overall incidence of adverse transfusion reactions in Chinese children was 0.79%[95%CI (0.54%, 1.04%)]. The incidence of adverse reactions of red blood cells, platelets and plasma were 0.34%[95%CI (0.15%, 0.54%)], 2.94%[95%CI (1.60%, 4.28%)] and 0.31%[95%CI (0.19%, 0.43%)], respectively. The incidence of fever reaction and anaphylaxis reaction were 0.22%[95%CI (0.13%, 0.31%)] and 0.46%[95%CI (0.30%, 0.61%)] respectively. 【Conclusion】 The overall incidence of adverse transfusion reactions in Chinese children is low, but the incidence of adverse reactions of platelet transfusion is high, which needs further prevention and control.

Sampling data of fresh frozen plasma, cryoprecipitates and leukocyte-free platelet quality monitoring in Hebei Province from 2015 to 2021: a retrospective analysis / 中国输血杂志

【Objective】 To form the sampling data interval by retrospectively analyzing the sampling data of quality monitoring of fresh frozen plasma, cryoprecipitates and leukocyte-free platelets in all blood stations in Hebei Province during the past 7 years. 【Methods】 The data of blood component sampling from 12 blood station quality control laboratories in Hebei from 2015 to 2021 were collected. The FⅧ content and plasma protein content of fresh frozen plasma, the FⅧ content and fibrinogen content of cryoprecipitates, and the leukocyte residuals, red blood cell mixed and platelet content of leukocyte-free platelets were taken as the objects for discrete point and fitted curve analysis. 【Results】 The FⅧ level of fresh frozen plasma: (1.36±1.1) IU/mL, 5 blood stations showed a representative overall high or low or fluctuated characteristics; Fresh frozen plasm-plasma protein items: overall mean ±SD: (61.13±16.7) g/L, four blood stations showed scattered distribution or continuous high value scattered points; Cryoprecipitates FⅧ: the overall mean ±SD: (134.25±58.7) IU/mL, four blood stations showed the differentiation characteristics of continuous high, low or stable in the middle; Cryoprecipitates-fibrinogen items: the overall mean ±SD: (215.27±83.5) mg, five blood stations showed the overall high or low and fluctuated. Leukocyte-free apheresis platelet-to-leukocyte residual items: overall mean ±SD: 0.37±0.96 (×106/bag), two blood stations showed a relatively high representative overall characteristics, and the rest were concentrated between 0 and 1; The total mean ±SD of platelet-to-red blood cell mixture without leukocyte was 2.45±2.82 (×109/bag), with obvious segmented concentrated distribution, and scattered distribution in 3 blood centers. Platelet content: the overall mean ±SD was 3.14±1.55 (×1011/bag), many deviations were noticed in 3 blood stations, and 1 blood station showed representative overall high characteristics. 【Conclusion】 This analysis shows that the distribution status of each blood station in different items is similar. The distribution status of discrete point groups and the change trend of the concentrated part of the fitting curve show that there are some differences in the monitoring level between the quality control laboratories of each blood station, and the update of detection instruments and reagents and the selection of detection methods greatly affect the test results. The summary data presented the index interval framework formed in the past 7 years, which helped to understand the difference between the results of each laboratory, correct the accuracy of the test results, better play the guiding role of quality monitoring in the blood preparation process, and continue to enhance the standardization of the whole process of blood collection and supply in the province.

A CLINICOHAEMATOLOGICAL PROFILE OF ADVERSE TRANSFUSION REACTIONS AND ITS ASSOCIATION WITH BLOOD COMPONENTS

Different blood components are associated with various types of adverse transfusion reactions and are linked to several factors including the number, rate and volume of transfusions. The given study was conducted to study the relationship between various transfusion reactions and its causative factors. This study was a prospective study carried out over eighteen months on all patients who received a blood transfusion and blood components including various adverse reactions and events related to transfusion. These were correlated with tests for compatibility including general blood picture ,tests for haemolysis ,hematuria and haemoglobinuria, Coombs Test (Direct and Indirect), culture along with relevant clinical details of the patient. Out of a total of 31451 units of blood issued, 47 adverse transfusion reactions were noted with a maximum number in the age group of > 18 years (87.3%) with M: F being 1.6: 1 .0.24% of adverse transfusion reactions were by Packed red blood cell transfusion and mostly were immediate transfusion with a mean volume of 100 ml and mean time of 20 minutes. Febrile Non Hemolytic Transfusion Reaction (FNHTR) was the most common Adverse Transfusion Reaction (ATR)(0.128%) with 2 cases positive for Direct Coombs Test. A thorough serological and immunological examination and the addition of methods like buffy coat reduction and leucocyte filtration help in reducing the incidences of hemolytic transfusion reactions and transmitted infections and establishing a hemovigilance system help in the attainment of the goal of safe transfusion

Evaluation of Causes and Rate of Wastage of Blood and its Components – An Important Quality Indicator in Blood Banks.

Background: The evaluation of wastage of blood products represents an important element in the appropriate use of blood components, a critical control point in the system of blood administration. Discarding or wastage of blood can be attributed to several reasons namely time expiry, wasted import, non-usage of ordered blood, broken bags and seal with leakage, hemolytic reasons, clotted blood, returned after 30 min, and miscellaneous others.Wasting of blood and blood components are an inefficient use of resources and may be avoided. The present study was undertaken with aim of primarily to determine the frequency of blood products wasting and secondarily to determine the factors that affect blood products wastage at our institute. Methods: The present study is a retrospective cross sectional descriptive study conducted in a tertiary teaching hospital located in South Delhi catering to low socioeconomic population. Blood component wastage was defined as components that did not meet the required standards of hospitals or fractionation centres during collection, processing and storage. The main reasons included expiry date, inappropriate volume, haemolysis of red blood cells (RBCs), contamination of plasma or platelets with RBCs, blood bag leakage, reactive infectious disease tests and inappropriate temperature during storage or transportation. The required data from clinical units and blood bank were collected and analyzed for a period of 7 years. Results: A total of 13728 blood units were received during the specified period. Overall wasted factor was of 18.5% with maximum wastage of platelet concentrate units (53.7%). Analyzing the causes of blood and blood product wastage in the hospital for this study showed that blood and blood product wastage were associated with many causes of which the common causes, included the expiration of the usability period (69.2%), sero-reactivity for infectious diseases (13.7%) and Quality Control units (9.2%). Conclusion: Blood is an irreplaceable precious resource which needs to be properly utilized with minimal wastage. Although present study was limited due to its retrospective nature but it still outlines the importance to emphasize that measures should be taken into account for formulating guidelines, effective policies, and training efforts for personnel.

O grupo sanguíneo predominante foi O, a maioria fator Rh positivo. O tórax foi o local mais comum de trauma. A maioria dos casos foi relacionada a trauma penetrante, sendo 53,6% por armas de fogo e 8,5% por armas brancas. As medianas do Escore ABC, de concentrado de hemácias e de plasma fresco usados foram de 2. 29,7% tiveram óbito em 24 horas e apenas o local do trauma - abdome - revelou-se como fator protetor para esse desfecho. Conclusão: observou-se a inexistência de associações significativas entre as variáveis do protocolo e o desfecho clínico de óbito.

Introduction: Trauma is one of the main causes of death in the world and hemorrhage is responsible for 30% to 40% of trauma-related mortality. The establishment of a massive transfusion protocol (TMP) offers the opportunity for preventive measures to control damage to the patient with severe hemorrhagic shock. Objective: to analyze epidemiological data of patients submitted to the MTP in a trauma reference institution. Methods: this is a study retrospective with a quantitative approach, involving patients undergoing MTM from January to December 2018. Blood data, patient identification, trauma site, accident type, clinical information and outcome were obtained through review of medical records and information collected at the hospital transfusion center. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) version 23. Results: 306 patients were evaluated, there was a predominance of males and ages from 18 to 30 years. 55.9% of the patients were from Fortaleza. The predominant blood group was O, being the majority with Rh positive factor. The thorax was the most common site of trauma. Most cases were related to penetrating trauma, being 53.6% for firearms and 8.5% for white weapons. Median ABC score, concentration of red blood cells and fresh plasma used were 2. 29.7% were dead in 24 hours and only the trauma site - abdomen - was revealed as a protective factor for this outcome. Conclusion: it was observed, after completing the study, the inexistence of significant associations between the protocol variables and the clinical death outcome.

Effect of the COVID-19 pandemic on blood donations and transfusions in Nigeria ­ A multi-facility study of 34 tertiary hospitals

Background: The coronavirus disease 2019 (COVID-19) pandemic affected blood supplies globally. Mobile blood drive campaigns halted, and voluntary blood donations reduced, challenging available blood supplies. Furthermore, fears of virus transmission led to deferrals of elective surgeries and non-urgent clinical procedures with noticeable declines in blood donations and transfusions. Aims: We aimed to assess the effect of the COVID-19 pandemic on the number of blood donations and transfusions across the country by blood product type across various hospital departments. Materials and Methods: A retrospective descriptive study was conducted to determine the impact of the COVID-19 pandemic on blood services in 34 tertiary hospitals in Nigeria, comparing January to July 2019 (pre-COVID-19) to January to July 2020 (peri-COVID-19). Data were collected from the country's web-based software District Health Information System, Version 2 (DHIS2). Results: A 17.1% decline in numbers of blood donations was observed over the study period, especially in April 2020 (44.3%), a 21.7% decline in numbers of blood transfusions, especially in April 2020 (44.3%). The largest declines in transfusion were noted in surgery department for fresh frozen plasma (80.1%) [p = 0.012] and accident and emergency department transfusion of platelets (78.3%) [p = 0.005]. The least decline of statistical significance was observed in internal medicine transfusions of whole blood (19.6%) [p = 0.011]. Conclusions: The COVID-19 pandemic significantly affected the numbers of blood donations and transfusions in Nigeria. Strengthening blood services to provide various blood components and secure safe blood supplies during public health emergencies is therefore critical.

An intelligent new method for batch weighing of blood components / 中国输血杂志

【Objective】 To establish a method for batch weighing blood components intelligently and accurately. 【Methods】 Virus inactivated plasma was used as weighing samples. The traditional electric scale and cryoprecipitation preparation instrument were used to weigh plasma with five specifications. The consistency of the weighing results by the two methods was statistically analyzed. Two groups of virus inactivated plasma with basically the same number of bags were randomly selected, and weighted by the same group of staff using these two equipment, the time for weighing and the time from weighing to registering were calculated statistically. 【Results】 227 bags of plasma were weighed in batches by the two methods, and statistical analysis showed no significant difference in standardized blood volume. There was no significant difference in plasma weighing time (71/68)by the same staff, weighing basically the same number of bags. However, the time difference from weighing to registering was statistically significant, as the new method was 2.65 s shorter than the traditional one (P<0.05). 【Conclusion】 The new method is accurate for batch weighing, and can realize the informatization and intellectualization of blood weighting. The time consumed from weighing to registration was improved by the new method, but not in time for weighing.

Systematic evaluation and classification of adverse reactions to incompatible blood component transfusion in patients undergoing ABO-incompatible allogeneic hematopoietic stem cell transplantation / 中国输血杂志

【Objective】 To analyze and evaluate the occurrence of adverse reactions to incompatible blood component transfusion in patients undergoing ABO-incompatible allogeneic hematopoietic stem cell transplantation (ABO-incompatible allo-HSCT) in our hospital, and provide a basis for clinical safety management of incompatible blood component transfusion. 【Methods】 The case data of 467 ABO-incompatible allo-HSCT patients with incompatible blood components transfused in our hospital from June 2021 to December 2021 were retrospectively analyzed, and the adverse reactions to blood transfusion that occurred were diagnosed according to the clinical manifestations and changes before and after blood transfusion as well as the results of related laboratory tests. The evaluation was based on three aspects as the degree of certainty of the type of reaction, the severity of it, and its probablity associated with blood transfusion. 【Results】 The overall incidence of adverse reactions to transfusion of incompatible blood components was 30.19% (141/467). The incidence occurred in suspended red blood cells were 42.86%(15/35), apheresis platelets 39.25%(73/186), frozen plasma 28.26%(26/92), cryoprecipitated coagulation factors 19.05%(8/42) and washed red blood cells 16.96%(19/112). The incidence of adverse reactions of washed red blood cells and suspended red blood cells was statistically different(P<0.05). The types of adverse reactions were mainly allergic reactions (67.37%, 95/141), followed by non-hemolytic febrile reactions (22.69%, 32/141), transfusion-related graft-versus-host disease(2.84%, 4/141), acute hemolytic transfusion reactions(2.84%, 4/141), transfusion-related hypotension(2.84%, 4/141) and 2 cases (1.42%, 2/141) of other adverse reactions. A total of 141 adverse reactions were graded: 113 cases (80.14%, 113/141) were " sure" , 20 cases (14.19%, 20/141) were " basically sure" , 8 cases were " suspected" (5.67%, 8/141); 130 cases (92.20%, 130/141) were " mild" , and 10 cases (7.09%, 10/141) were" moderate" , 1 case was " severe" (0.71%, 1/141). As to the occurrence associated with blood transfusion: 117 cases (82.98%, 117/141) were " highly correlated" , 17 cases (12.06%, 17/141) were " likely correlated" , and 7 cases (4.96%, 7/141) were " less correlated" . 【Conclusion】 Evaluating and grading the adverse reactions to transfusion of incompatible blood components can deepen the cognition of clinical medical staff, increase the accuracy and rigor of their judgment of adverse reactions, and avoid the missed and false reports of adverse reactions to a certain extent, which laid the foundation for the establishment of a unified standard for adverse reactions to incompatible blood transfusion.

Blood components use at two private hospitals in Belo Horizonte, Minas Gerais between July 2017 and June 2019

ABSTRACT Introduction: A retrospective ecological longitudinal study was carried out with data on blood components use from two private hospital units that belong to the same organization located in Belo Horizonte between July 2017 and June 2019. Objectives: To describe the monthly series of red blood cells, platelets and plasma use and the rate of blood components use for general hospitalizations in the health network, from the perspective of time series. Methods: A total of 15 time series were created with monthly data related to the use of blood components. The stationarity of the series was verified by the unit root test, the trend, by the Cox-Stuart test and seasonality, by the Fisher test (significance levels of 10% for the first test and 5% for the last two). Results: All series tested positive for the trend component and showed an increasing trend for the use of blood components. Ten series showed statistically significant seasonality and eight series were identified as non-stationary. The percentage of transfusions of blood components due to hospitalization at hospitals 1 and 2 was 29% (22% at hospital 1 and 38.9% at hospital 2). Conclusion: This study was able to describe the components of blood components use dynamics, from the perspective of time series at hospitals. Due to the growing trend in demand for blood components and their high cost, we propose the reduction of blood components use and the expanded use of alternative blood transfusion strategies.

Complicaciones postransfusionales en pacientes pediátricos con leucemia / Post-transfusion complications in pediatric patients with leukemia

Introducción: El cáncer pediátrico es un importante problema de salud pública y el más frecuente es la leucemia. En ocasiones, esta enfermedad puede generar depleción de las líneas celulares y es la transfusión de hemocomponentes un importante pilar de su tratamiento. Este procedimiento puede generar reacciones postransfusionales que pueden ser letales. Objetivo: Exponer las diferentes características clínicas y epidemiológicas de las reacciones postransfusionales en población pediátrica con leucemia. Métodos: Se realizó una búsqueda sistemática en las principales bases de datos de literatura médica. Se incluyeron 46 artículos. Resultados: La complicación más frecuente es la reacción febril no hemolítica. También es frecuente la sobrecarga de hierro. El factor de riesgo más importante para presentar esta sobrecarga es el número de transfusiones. Es necesario monitorizar la cantidad de hierro hepático. La reacción pulmonar aguda relacionada con la transfusión es una condición potencialmente mortal. Las infecciones pueden presentarse y pueden ser mortales dada la inmunosupresión de este grupo de pacientes. Otras reacciones inmunológicas pueden ser raras, pero deben ser tenidas en cuenta. Consideraciones finales: Las reacciones postransfusionales pueden ser más graves en los pacientes con leucemia. Se requiere realizar estudios con modelos epidemiológicos adecuados para identificar las reacciones postransfusionales más frecuentes en población pediátrica con esta enfermedad(AU)

Introduction: Pediatric cancer is a major public health problem and leukemia is the most common. Sometimes this disease can lead to depletion of cell lines and the transfusion of blood components is an important pillar of their treatment. This procedure can generate post-transfusion reactions that can be lethal. Objective: Show the different clinical and epidemiological characteristics of post-transfusion reactions in pediatric population with leukemia. Methods: A systematic search was carried out in the main databases of medical literature. 46 items were included. Results: The most common complication is the non-hemolytic febrile reaction. Iron overloading is also common. The most important risk factor for this overload is the number of transfusions. It is necessary to monitor the amount of iron in the liver. Acute transfusion-related pulmonary reaction is a life-threatening condition. Infections can occur and can be fatal given the immunosuppression of this group of patients. Other immune reactions may be rare, but they should be taken into account. Final considerations: Post-transfusion reactions may be more severe in patients with leukemia. Studies with appropriate epidemiological models are required to identify the most common post-transfusion reactions in the pediatric population with this disease(AU)

Suministro y demanda de sangre durante la pandemia de COVID-19. Una revisión / Blood supply and demand during the COVID-19 pandemic. A review

Resumen La propagación tan rápida del nuevo coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2), que se informó por primera vez en Wuhan (China) a finales de diciembre de 2019, y produce la enfermedad caracterizada por neumonía llamada enfermedad por coronavirus 2019 (COVID-19), ha causado un impacto significativo en los sistemas de salud en todo el mundo y la interrupción de la vida cotidiana. A finales de junio el número de casos confirmados es de 9,188,362 millones, con más de 474,339 muertes, y aproximadamente 4,937,282 personas recuperadas. Las estrictas medidas para restricción de la movilidad y medidas de distanciamiento social impuestas por los gobiernos, más el miedo y pánico resultado de manera abrumadora entre el público general, ha comprometido de manera importante la sostenibilidad del suministro de sangre segura, el cual se vuelve particularmente desafiante. La demanda de sangre y productos sanguíneos puede disminuir durante una pandemia debido al aplazamiento de cirugías electivas. Medidas como el distanciamiento físico y el bloqueo total de las ciudades, las provincias o países que intentan frenar la propagación de la infección pueden provocar una disminución importante en el suministro y una escasez general de productos sanguíneos.

Abstract The rapid spread of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first reported in Wuhan (China) in late December 2019, and produces the disease characterized by pneumonia called coronavirus disease 2019 (COVID-19), has caused a significant impact on health systems worldwide and disruption of daily life; at the end of June the number of confirmed cases is 9,188,362 million with more than 474,339 deaths, and approximately 4,937,282 people recovered. Strict measures to restrict mobility, social distancing measures imposed by governments, plus overwhelming fear and panic among the general public, have significantly compromised the sustainability of the safe blood supply, it becomes particularly challenging. The demand for blood and blood products may decrease during a pandemic due to the postponement of elective surgeries, measures such as physical distancing and the total blockade of cities, provinces or countries that try to stop the spread of the infection can cause a significant decrease in the supply and a general shortage of blood products. Hospitals must have a blood management plan for emergencies in preparedness planning on the sustainability and safety of the blood supply. This review considers the impact of the COVID-19 pandemic on blood supply and specifies important aspects of donor management, and the proper use of blood components.

Blood component quality sampling: the use of characteristic curve scheme / 中国输血杂志

【Objective】 To explore the optimal sampling scheme for functional indexes of blood components, so as to ensure the accuracy of sampling. 【Methods】 The operation characteristic curves of 5 sampling schemes as (4, 1), (6, 1), (8, 2), (10, 2) and (12, 3) were drawn based on the characteristic curve theory of sampling inspection, the discriminability of those 5 sampling schemes was compared, and the risk of misjudgment and omission of sampling schemes was analyzed. 【Results】 The discriminability of 5 sampling schemes from high to low were (10, 2), (6, 1), (12, 3), (8, 2) and (4, 1), ; the operation characteristic curves of scheme (10, 2) were in basic concordance with (6, 1), (12, 3) and (8, 2) as the percent defective was <0.25. The risk of misjudgment of the 5 sampling schemes was low, and the risk of omission was high in scheme (4, 1)(0.738, 3), and low in (10, 2) and (6, 1) (0.525 6 and 0.533 9, respectively). 【Conclusion】 On the premise of strictly controlling the process of blood collection and supply and ensuring the quality of blood preparations, the sampling scheme (4, 1) can effectively monitor the stability of the whole process. However, for blood preparations with high nonconforming rate, sampling scheme (6, 1) or (10, 2) was recommended as the sampling amount should be elevated appropriately.

Blood collection and supply in Tianjin: Statistics and regularity analysis from 2010 to 2019 / 中国输血杂志

【Objective】 To analyze and characterize the trend of blood collection and supply in Tianjin from 2010 to 2019, so as to provide references for respective working plans in Tianjin Blood Center. 【Methods】 Through the blood information management system, the issued amount of various blood components from Tianjin Blood Center from 2010 to 2019 was statistically analyzed; the number and respective data of blood donors in Tianjin in recent 10 years were sorted out and analyzed. 【Results】 From 2010 to 2019, the amount of issued blood components in Tianjin Blood Center increased year by year, with an average annual growth rate of 3.22%(×100%). The utilization rate of blood components in clinical increased year by year, reaching 99.99%(642 240.2/642 250.2)by the end of 2019.The consumption of platelets and cryoprecipitated coagulation factor increased rapidly, accounting for 8.89%(57 111.0/642 250.2)and 2.65%(16 989.0/642 250.2), respectively. In recent 10 years, a total of 1 473 172 blood donors have donated blood voluntarily, and the number increased steadily. Among the blood donors, those aged 18-35 took up the largest proportion, reaching 79.13%(116 5548/1 473 172). The ratio of male to female was about 3∶1, with male blood donors accounting for the vast majority.The main blood donors were students, staff and workers. In 2018, the blood donation rate in Tianjin was only 12.2‰, which lagged behind provincial capital cities and economically developed areas in terms of blood collection units per capita and other indicators. 【Conclusion】 Although blood collection and supply in Tianjin is generally developing scientifically and reasonably, the current situation is still very serious.It is necessary to formulate and improve blood donation strategies according to actual situations. The data in this study is helpful inguiding advance planning, overall construction and scientific development of future blood collection and supply in Tianjin.

Quality control in the different stages of producing red blood cell concentrate from dogs / Controle de qualidade nas diferentes etapas de produção do concentrado de hemácias em cães

The objective of this study was to perform a quality control assessment of red blood cells after standardization of the blood production stages. For this purpose, separation of the blood components to obtain red blood cells, the storage of the blood packets and an evaluation of blood quality were performed. The mean (± SD) volume, globular volume, hemoglobin and hemolysis percentage of the red blood cell concentrate were 299.77±30.08mL, 60.87±2.60%, 20.57±0.93g/DL and 0.09±0.07%, respectively. The means (± SD) of the volume, globular volume, total hemoglobin percentage of hemolysis and hemoglobin per unit of packed red blood cells after the storage period (8.83±6.73 days) were 57.55±3.01%, 20.30±0.89 0, 20±0.12%, and 60.90±7.65. The red blood cell packets were within the parameters of quality control established by Health Ministry legislation in humans and allow us to conclude that the standardization of blood production stages involves the selection of donors until the end of storage and is necessary to produce quality red blood cells. Quality control aims to find possible flaws in the procedures to be repaired, increasing transfusion safety.(AU)

Prospective observational study for appropriateness of blood and blood components therapy in children up to 16 years of age admitted in a tertiary care hospital

Background: Blood component therapy is a rational replacement therapy of proven clinical value and efficacy, but it is a double-edged sword as it is associated with many hazards of transfusion reaction. Because of ease of availability and gap in the knowledge of medical professional's blood products are being used very liberally leading to huge mismatch in the demand and supply of life saving blood product.Methods: Prospective cross-sectional observational study was done over a period of 1 year in a tertiary hospital, in western part of India. 225 events of blood component therapy were studied in neonates (<1month) and pediatric (1month-16years) age groups. Indications and reactions to blood components therapy were studied in both the groups. Each component therapy was considered as one event and its indication was compared with standard guidelines for terming it as appropriate or inappropriate.Results: Out of total 225 events of transfusions, most commonly used was PRBC (48.9%) followed by FFP (24.9%), platelet (16.0%), IVIG (9.8%) and whole blood (0.4%).' Authors found that overall 17.3% of the component therapy' were inappropriate( neonates 10.2%' and 7.1% in the rest). Most commonly misused blood product was FFP (37.5%) followed by IVIG (22.7%), platelets (16.7%) and PRBC (6.4%).Conclusions: Regular audit of blood and its component usage is essential to assess the blood utilization pattern and set ideal policies in all the medical specialties to make it appropriate, ensure availability and save patients from its hazards.
