ABSTRACT

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.


Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

ABSTRACT

Introduction: The rates of request and use of blood concentrates are still poorly reported in the literature. This study aimed to analyze the rates of requests for blood concentrates and their use in patients undergoing emergency surgery in a teaching hospital. Methods: A retrospective, quantitative and descriptive study was conducted in 359 medical records of patients in urgent surgery scheduled with a request for a reserve of blood concentrate. The ratios between crossmatched and transfused units (C/T), transfusion index (TI), and probability (TP) were calculated, and the times between request and delivery at the transfusion agency (TA) and patient admission to the surgical center (SC). Results: The mean age was 58.5 ± 22.2 years, with the majority being male (53.1%). There was an average of 27.5 monthly requests (min 12, max 44). Ninety-seven units of blood concentrates were transfused into 44 patients (C/T ratio 7.59; TI 0.27; TP 12.3%). Only seven patients had their requests made after admission to the OR. The median time between the request and arrival at the TA was 1h15min, while that between the request and the patient's arrival at the SC was 5h23min. There was greater transfusion in major surgery (major 37, 14.8% vs. medium 7, 6.5%; p = 0.027) and non-orthopedic surgery (orthopedic 9, 4.0% vs. non-orthopedic 35, 26.9%; p < 0.001). Conclusion: there was a significant discrepancy between the number of requests for blood reservation and its real use and an increased time between reservation requests and their arrival at the TA.

ABSTRACT

According to the World Health Organization, trauma from external causes remains the major cause of death and disability among people aged from 5 to 29 years old.1 In order to reestablish hemodynamic stability and adequate hemostasis of these patients, without the dilutional effects of infusing large volumes of crystalloids, the concept of hemostatic resuscitation was developed.2 The purpose of this report is to discuss a case in which hemostatic resuscitation was performed quickly, resulting in a good macro-hemodynamic response of the patient at the first prehospital transfusion service in Latin America.

ABSTRACT

El acceso universal a las transfusiones de sangre depende de diversos factores localizados dentro y fuera de los servicios de salud. Motivados por ser este un tema infrecuente, el trabajo tiene el objetivo de analizar desde una perspectiva multidimensional y holística los determinantes externos de la disponibilidad de sangre para las transfusiones. El desarrollo socioeconómico constituye un importante factor dinamizador porque condiciona, de cierta manera, la infraestructura del sistema sanitario e incide sobre los factores epidemiológicos, sociodemográficos y jurídicos. A su vez, estos influyen en la organización de las actividades y la complejidad de la asistencia sanitaria, factores que otorgan un sentido positivo o negativo a la disponibilidad de sangre. Tomarlos en consideración al diseñar las políticas de salud relacionadas con el uso de la sangre permite una mayor precisión en las intervenciones locales que contribuyan a mejorar la seguridad de las transfusiones(AU)


Universal access to blood transfusions depends on a number of localized factors both inside and outside health services. Motivated by being an infrequent topic, this work aims to analyze from a multidimensional and holistic perspective the external determinants of the availability of blood for transfusions. Socio-economic development is an important dynamic factor because it conditions, in a certain way, the infrastructure of the health system and affects epidemiological, sociodemographic and legal factors. In turn, these influence the organization of activities and the complexity of health care, factors that give a positive or negative meaning to the availability of blood. Taking them into consideration when designing health policies related to the use of blood allows greater precision in local interventions that contribute to improving the safety of transfusions(AU)

ABSTRACT

Abstract Introduction Sickle cell anemia is a monogenic disorder caused by a mutation in the β-hemoglobin gene, resulting in sickle hemoglobin that can polymerize. Presentation and clinical course have significant inter-individual variability and classifying these patients for severity is a challenge. Methods We applied hierarchical clusters with 10 routine laboratory tests to understand if this grouping could be associated with clinical manifestations. We included 145 adult homozygous patients (SS) at an outpatient clinic in a retrospective study. Results We found five clusters by counting those that had been differentiated by unconjugated bilirubin, reticulocytes, LDH, leukocytes, lymphocytes and monocytes. When comparing groups to clinical findings, the clusters were different only for liver abnormality. Cluster 3 had the lower median of reticulocytes, LDH, leukocytes, lymphocytes and monocytes and a higher percentage of patients under treatment. Clusters 4 and 5 had higher frequencies of liver impairment and higher medians of reticulocytes, LDH, leukocytes, lymphocytes and monocytes. Hemolysis and inflammation seemed to influence the grouping. Conclusion In our study, cluster analysis showed five groups that exhibited different degrees of inflammation and hemolysis. When comparing clinical data, the result was different only for the criteria of liver abnormality.

ABSTRACT

Introduction: Sexually transmitted infections (STIs) are a serious public health problem, and some of these infections are also transmitted through blood transfusions. Objective: To identify publications in scientific journals in Brazil and in the world showing if there is an important association between serological inadequacy due to sexually transmitted infections traced in blood and blood products used for medical use. Methods: Systematic review of articles published from 2018 to 2023, using the LILACS, SciELO and PubMed databases, with a concomitant approach to the issues of serological disability and STI. Original studies or review articles in Portuguese, English and Spanish with Brazilian and international data were included. Editorial publications, letter to the editor, letter from the editor or comments on the subject were excluded. Results: The search found 571 articles, of which 106 (18.40%) met the inclusion criteria, that is, Serological disability and STI. In studies with international data, the prevalence of donors with hepatitis C ranged from 0.12 to 4.8%; with hepatitis B, from 1.3 to 8.2%; with HIV, from 0.0021 to 2.5%; with syphilis, from 1.73 to 2.4%; with HTLV, 0.66%; and with Chagas disease, from 0.017 to 2.76%. Among articles with Brazilian data, the prevalence of donors with seroreactive tests for hepatitis C ranged from 0.18 to 1.76%; with hepatitis B, from 0.05 to 7.9%; with HIV, from 0.03 to 0.82%; with syphilis, from 0.37 to 3.51%; with HTLV, from 0.02 to 0.3%, and with Chagas disease, from 0.8 to 0.5%. Conclusion: STIs are rarely discussed in the scientific literature in studies on serological inadequacy. In addition, a minority of articles were with Brazilian data. However, results show that STIs, despite being little discussed in the scientific literature in studies on the subject of serological inadequacy, have statistically significant percentages of seropositivity for STIs. Moreover, hepatitis C and B have a relevant seroprevalence, reaching 8.2% and 4.8%, respectively, in the international scenario. In Brazil, hepatitis B continues to occupy a prominent place with a seroprevalence of up to 7.9%. However, syphilis now holds a very important role, with a maximum percentage of 3.51%. More studies are needed for further reflection: although STIs are little addressed in studies about serological inadequacy in human blood banks, would they contribute to the maintenance and non-reduction of the general frequency of infections transmitted by blood transfusion


Introdução: As infecções sexualmente transmissíveis (IST) são um grave problema de saúde pública e algumas dessas infecções, também, transmitidas por intermédio de transfusões de sangue. Objetivo: Identificar publicações em periódicos científicos no Brasil e no mundo sobre se existe importante associação entre inaptidão sorológica por infecções sexualmente transmissíveis rastreadas em sangue e hemoderivados usados para uso médico. Métodos:Revisão sistemática de artigos publicados no período de 2018 a 2023, usando as bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), Scientific Electronic Library Online (SciELO) e United States National Library of Medicine (PubMed) com abordagem concomitante para os assuntos de inaptidão sorológica e IST. Incluíram-se estudos originais ou artigos de revisão nos idiomas português, inglês e espanhol com dados brasileiros e internacionais. Foram excluídas publicações do tipo editorial, carta ao editor, carta do editor ou comentários sobre o tema. Resultados:A busca localizou 571 artigos dos quais 106 (18,40%) se encaixavam nos critérios de inclusão, ou seja, inaptidão sorológica e IST. Em estudos com dados internacionais, a prevalência de doadores com hepatite C variou de 0,12 a 4,8%; com hepatite B de 1,3 a 8,2%; com HIV de 0,0021 a 2,5%; com sífilis de 1,73 a 2,4%; com HTLV 0,66%; e com doença de Chagas de 0,017 a 2,76 %. Já entre os artigos com dados brasileiros, a prevalência de doadores com exames soro-reatores para hepatite C variou de 0,18 a 1,76%; com hepatite B de 0,05 a 7,9%; com HIV de 0,03 a 0,82%; com sífilis de 0,37 a 3,51%; com HTLV 0,02 a 0,3%, e com doença de Chagas de 0,8 a 0,5%. Conclusão: As IST são pouco abordadas na literatura científica em estudos com o tema inaptidão sorológica. Além disso, uma minoria de artigos era com dados brasileiros. Entretanto, resultados demonstram que, apesar de pouco abordadas na literatura científica em estudos com o tema inaptidão sorológica, as IST possuem percentuais de soropositividade estatisticamente significativos. Além disso, as hepatites C e B possuem soroprevalência relevante, podendo chegar a 8,2 e 4,8%, respectivamente, no cenário internacional. Já no cenário nacional, brasileiro, a hepatite B continua ocupando um lugar de destaque, com soroprevalência de até 7,9%. Todavia, a sífilis passa a ocupar um papel de altíssima relevância, com percentual máximo de 3,51%. São necessários mais estudos para mais reflexão: apesar de as IST serem pouco abordadas em estudos acerca da inaptidão sorológica em bancos de sangue humano, seriam elas contribuintes para a manutenção e a não redução da frequência geral de infecções transmitidas por transfusão sanguínea?

ABSTRACT

Introducción: actualmente, la indicación principal para la transfusión de FFP es corregir la deficiencia de los factores de coagulación en pacientes con hemorragia activa o sugestión de esta, sin embargo, la práctica clínica ha demostrado que un porcentaje grande de las transfusiones de FFP en neonatología no siguen las recomendaciones de las guías actuales y, en su mayoría, son innecesarias. Objetivo: ampliar el conocimiento que se tiene sobre la transfusión de FFP en neonatología y la implementación de la tromboelastografía para evitar realizar estas intervenciones. Metodología: se realizó una revisión de la literatura en la base de datos PubMed y Elsevier, usando palabras clave como tromboelastografía, transfusión de plasma en neonatos, hemostasia neonatal. Conclusión: se evidenció que los tiempos de coagulación de los neonatos y prematuros sanos son más prolongados en comparación a los adultos, por ello facilita su errada cuando se habla de transfusión de FFP, de ahí que la TEG sea una buena herramienta para evaluar el estado coagulante de los neonatos de manera integral, sin abrir paso a errores de interpretación y facilitando la decisión de tratamientos en los pacientes en UCIN, antes de requerir transfusiones de FFP.


Introduction: Currently the main indication for FFP transfusion is to correct coagulation factor deficiency in patients with active bleeding or its suggestion, however, clinical practice has shown that a large percentage of FFP transfusions in neonatology do not they follow current guideline recommendations and are mostly unnecessary. Objective: To expand the knowledge about these transfusions in neonatology and the implementation of thrombelastography to avoid performing these interventions. Methodology: A review of the literature was carried out in the PubMed and Elsevier databases, using keywords such as "thrombelastography", "plasma transfusion in neonates", "neonatal hemostasis". Conclusion: It was evidenced that the coagulation times of healthy neonates and premature infants are longer compared to adults, thus facilitating their misinterpretation and limiting their use when talking about FFP transfusion, therefore TEG is a good tool. to evaluate the coagulation interpretación y limita su utilización status of neonates in a comprehensive manner, without giving way to interpretation errors and facilitating treatment decisions in patients in the NICU before requiring FFP transfusions.

ABSTRACT

Abstract Introduction In the current scenario, in which evidence-based medicine is almost obligatory, therapeutic approaches are increasingly being restricted to measures that are proven to bring benefits to the patient. Transfusion therapy follows the same concept. Even though it can be an essential support procedure in some situations, it must be carefully used, exclusively in situations in which the literature assures scientific support for its usage. Transfusion exposes patients to risks and complications, so it is necessary that we, as doctors, continue working to reduce possible mistakes involving the practice of this type of therapy. Objective To analyze if the red blood cell requests are properly made, analyzing the indication written on them (by the doctor, comparing them to the references in the actual literature. Method In this research, we have analyzed and reviewed the requests for red blood cell concentrates between August and September of 2018 received at the Hematology and Hemotherapy Center studied to find the most common mistakes made by requesters/doctors. Results A total of 397 of the 754 analyzed requests were evaluated as inadequate. Therefore, 1 out of every 2 transfusions performed did not have their requests properly completed in the city of Cascavel, Paraná. Conclusions The number of inappropriate requests was high during the studied period, especially when compared to studies available in the literature. The number of inadequacies suggests that the blood component requests and the subsequent evaluation by the transfusion agency needs to be better addressed in clinical practice.

ABSTRACT

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.


A transfusão maciça apresenta desafios clínicos, organizacionais e logísticos para o pessoal de saúde em geral e para os serviços de Medicina Transfusional em particular. Não existe uma definição universalmente aceita de transfusão maciça; as definições mais comumente usadas são baseadas no número de unidades de sangue administradas em um determinado período de tempo. A maioria dos eventos de transfusão maciça ocorre no contexto de sangramento maior em pacientes cirúrgicos, politraumatizados, com sangramento gastrointestinal ou obstétrico. Atualmente, a ressuscitação para controle de danos e os protocolos de transfusão maciça são as estratégias mais usadas para o tratamento inicial, seguidos por tratamento personalizado e orientado por objetivos usando monitoramento de coagulação em tempo real usando testes viscoelásticos. Há uma série de controvérsias em torno do tratamento ideal, incluindo o uso de sangue total, a proporção de componentes sanguíneos a serem usados, o uso de concentrados de fator de coagulação e a indicação ideal de ácido tranexâmico. O estudo dos produtos ideais para o tratamento de pacientes com sangramento maciço tornou-se uma área de grande interesse na pesquisa científica. O contexto clínico em que ocorreu o evento hemorrágico, o número de hemocomponentes transfundidos, a idade do paciente e as comorbidades são os preditores mais importantes de sobrevida a curto e longo prazo. Esta revisão narrativa explora o estado atual do conhecimento sobre transfusão maciça, bem como os avanços que podemos esperar no futuro próximo.

ABSTRACT

Objetivo: identificar as principais complicações ocasionadas pela transfusão sanguínea à saúde do idoso hospitalizado através da análise das evidências científicas. Método: revisão integrativa realizada com estudos em inglês provenientes de bases de dados nacionais e internacionais publicados no período de 2017 a 2021. Os principais descritores foram "Blood Transfusion", "Transfusion Reaction", "Aged" e "Hospitalization", combinados por meio dos operadores booleanos "AND" e "OR". Resultados: foram incluídos 23 estudos que retratavam as principais complicações da transfusão sanguínea para a pessoa idosa hospitalizada. As doze diferentes complicações foram alocadas em duas categorias: relacionadas a cirurgias ou complicações não-cirúrgicas. Maior tempo de permanência hospitalar, mortalidade, reações transfusionais, lesão renal aguda pós-operatória e delirium pós-operatório fizeram parte dos principais achados. Conclusão: os mecanismos pelos quais as complicações se desenvolvem ainda não estão totalmente esclarecidos, evidenciando a importância do estímulo à realização de novas pesquisas que envolvam esta temática.

ABSTRACT

Abstract Introduction Lewis antibodies have been thought to play a small role in clinical transfusion practice, but recent reports suggest that they have gained more importance in the context of transfusion and transplantation. Data regarding the prevalence of Lewis antibodies and their clinical significance in the Indian context is very limited. Hence, this study was aimed at analyzing the serological characteristics and clinical significance of Lewis antibodies encountered in our patient and donor populations. Methods The retrospective data analyzed the records of red cell antibody screening results and the additional serological evaluation performed on the donor and patient samples included in the study. Results A total of 26 study subjects were noted to have Lewis antibodies (including 6 healthy donors and 20 patients). Of them, 13 individuals had anti-Leb, 10 had anti-Lea and the remaining three had an anti-Lea/Leb mixture. IgG Lewis antibodies were detected in 7 individuals. All cases of IgM Lewis antibodies detected were reacting at 37°C. Two patients were suspected of having hemolytic transfusion reactions due to Lewis antibodies. Antigen-negative cross-match compatible units were provided for transfusion in the recipients. Conclusion Lewis antibodies of the IgM class reacting at 37°C should be regarded as clinically important. The present study findings urge that the lab personnel look for the thermal amplitude of Lewis antibodies, irrespective of the fact that the antibody class and antigen-negative crossmatch compatible units should be provided to avoid hemolytic transfusion reactions.

ABSTRACT

Background Blood transfusion saves human lives, but also it can be a route for TransfusionTransmissible Infections (TTIs) including Human Immuno-Deficiency Virus (HIV), Hepatitis B virus (HBV), Hepatitis C virus (HCV), and syphilis. Objective This study aimed to explore the risk factors associated with TTIs among blood donors at Regional Centre for Blood Transfusion (RCBT) of Karongi, Rwanda. Methods This was a retrospective cross-sectional study design conducted among 36,708 blood donors from 2015 to 2019. Data were extracted from the system known as eProgesaused and the outcome variable were TTIs including HBV, HCV and HIV (measured using Enzyme Immuno-Assay/Chemiluminescence Immunoassay) and syphilis (determined by Rapid Reagin Plasma). Descriptive statistics was computed to describe the characteristics of the blood donors. Bivariate and multivariable logistic regression were performed to assess the risk factors associated with TTIs. P value less than 0.05 was considered statistically significant. Results The study found that the overall prevalence of TTIs was 2.1%, while the prevalences of HBV, HCV, HIV, and syphilis were 1.3%, 0.4%, 0.06%, and 0.34%, respectively. Multivariable analysis showed that the factors associated with HBV, HCV, HIV and syphilis were being male, age more than 25 years, being married, living in urban areas, first time blood donors and blood donors living in Rusizi, Rusizi, Nyamasheke and Karongi districts. Conclusion This study revealed that the most frequent TTI was HBV among blood donors and the main risk groups were males, age group of 26-35 years, married and first time donors. Hence, while developing health policies to reduce the effects of HBV infection on safe blood transfusion, these study findings should be taken into account.

ABSTRACT

Anaemia is a global public health problem with high mortality and morbidity. It is also a common consequence of chronic kidney disease (CKD). There is a paucity of data on the actual burden of anaemia among patients on chronic haemodialysis (CHD) in Lagos, Nigeria. Objectives: To determine the prevalence and factors associated with the severity of anaemia among Nigerian patients undergoing chronic haemodialysis. Methods: This was a retrospective analysis of adult patients with end-stage renal disease (ESRD) on maintenance haemodialysis at the Lagos State University Teaching Hospital, Ikeja, Lagos. The data extracted from the clinical case files included the bio-demographic and clinical parameters, including the treatment modalities. Results: A total of 92 patients comprising 69 (75%) males and 23 (25.0%) females with the overall mean age of 48.2±14.0 years were included. Hypertension was the commonest aetiology of CKD and the average duration of haemodialysis was 16.6 months. The commonest access route for haemodialysis was a central line while 96.7% and 81.5% received erythropoietin and intravenous iron sucrose respectively. Seventy-three (79.3%) patients have had intra-dialysis blood transfusions in the past. Mild, moderate, and severe anaemia were recorded in 17%, 67%, and 16% respectively. The use of erythropoietin, iron sucrose, and increased frequency of blood transfusions correlated with the severity of anaemia. Conclusion: Anaemia is highly prevalent among patients with CKD on chronic haemodialysis. Increased frequency of blood transfusions, inadequate utilization of erythropoietin, and iron sucrose administration are associated with anaemia severity.

ABSTRACT

OBJECTIVE@#To investigate the distribution of irregular blood group antibodies in patients with malignant tumors, and to analyze the relationship between it and efficacy of blood transfusion in patients.@*METHODS@#5 600 patients with malignant tumors treated in Shanxi Bethune Hospital from January 2019 to December 2021 were selected as the research subjects. All patients received blood transfusion, and cross matching test was conducted before blood transfusion, irregular antibody results of patients were tested; the irregular distribution of blood group antibodies was observed, and the relationship between it and efficacy of blood transfusion in patients was analyzed.@*RESULTS@#Among 5 600 patients with malignant tumors, 96 cases were positive for irregular antibody, and the positive rate was 1.71%; the main blood group systems involved in the irregular antibody positive of 96 patients with malignant tumors were RH, MNSs and Duffy system, among which Rh blood group was the most common, and the proportion of anti-E was the highest; among the malignant tumor patients with positive blood group irregular antibody, the proportion of female was higher than that of male; the proportion of patients aged >60 years was the highest, followed by patients aged >40 and ≤50 years, and the proportion of patients aged 18-30 years was the lowest; the patients with positive blood group irregular antibody were mainly in blood system (including lymphoma), digestive system, reproductive and urinary system; the positive rate of irregular antibody of patients in the ineffective group was higher than that of patients in the effective group, the difference was statistically significant (P<0.05). Logistic regression analysis results showed that, irregular antibody positive was a risk factor for ineffective blood transfusion in patients with malignant tumor (OR>1, P<0.05).@*CONCLUSION@#The irregular blood group antibody positive of patients with malignant tumor are mostly female, and the proportion of patients aged >60 is the highest, which is mainly distributed in malignant tumors of blood system, digestive system and urogenital system, and the positive blood group irregular antibody is related to the efficacy of blood transfusion in patients.

ABSTRACT

OBJECTIVE@#To establish the diagnostic process of low titer blood group antibody in the occurrence of adverse reactions of hemolytic transfusion.@*METHODS@#Acid elusion test, enzyme method and PEG method were used for antibody identification. Combined with the patient's clinical symptoms and relevant inspection indexes, the irregular antibodies leading to hemolysis were detected.@*RESULTS@#The patient's irregular antibody screening was positive, and it was determined that there was anti-Lea antibody in the serum. After the transfusion reaction, the low titer anti-E antibody was detected by enhanced test. The patient's Rh typing was Ccee, while the transfused red blood cells were ccEE. The new and old samples of the patient were matched with the transfused red blood cells by PEG method, and the major were incompatible. The evidence of hemolytic transfusion reaction was found.@*CONCLUSION@#Antibodies with low titer in serum are not easy to be detected, which often lead to severe hemolytic transfusion reaction.

ABSTRACT

BACKGROUND@#Percutaneous nephrolithotomy (PCNL) is the standard of care for the treatment of renal stones >2cm and staghorn calculi. This minimally invasive procedure however has intraoperative hemorrhage as one of its most dreaded complications.@*OBJECTIVE@#To analyze the rate of hemorrhage and transfusion requirements among patients undergoing either PCNL or open stone surgery (OSS).@*METHODS@#This was a retrospective study conducted at the National Kidney and Transplant Institute Medical Records Department. Data were collected for the period of January 2018 to December 2019.@*RESULTS@#One hundred forty cases were included, 102 patients in the PCNL group and 38 in the OSS. The mean age 50.84±11.89 vs. 50.50±10.09 with male to female ratio of 1.2:1 for PCNL and open surgery, respectively. The most common comorbidity was hypertension (89, 63.6%). As regards stone size, majority had >4 cm stone size (61; 43.9%). In PCNL, there was no significant change noted in the hemoglobin (14.69±13.3 vs 12.03±1.91, p= 0.099) as compared to OSS, where there was significant decline (12.77±2.64 vs. 11.06±2.52; = .000. The number of packed red cell units for transfusion was also significantly higher in OSS compared to PCNL group (.526±.861 vs. 159±.502, p .020.)@*CONCLUSION@#In the treatment of staghorn calculi, PCNL incurs less blood loss and lower transfusion requirements compared to open stone surgery.

ABSTRACT

Os profissionais de enfermagem exercem um papel fundamental na segurança transfusional. A atuação da equipe de enfermagem não é limitada à apenas administrar os hemocomponentes, uma vez que tem a responsabilidade de prestar uma assistência livre de danos decorrentes de imperícia, negligência e imprudência. Portanto, esses profissionais devem ter conhecimento das boas práticas relacionadas ao ciclo produtivo do sangue e componentes, garantindo a qualidade dos processos e produtos, reduzindo os riscos sanitários e garantindo a segurança transfusional. Objetivo: Avaliar o conhecimento do enfermeiro sobre hemotransfusão, explorando os principais pontos da legislação que aborda o ciclo do sangue, enfatizando principalmente os conhecimentos necessários durante o ato transfusional. Materias e Métodos: Trata-se de um estudo exploratório, transversal, quantitativo, descritivo, realizado em um hospital de referência em urgência e trauma no estado de Goiás, sendo a coleta de dados estruturada por meio de questionário semi-estruturado, abordando os seguintes temas: legislação sobre o assunto, sistema ABO e Rh, bolsa de coleta, tempo de administração, reação adversa imediata e tardia. Resultados: A amostra foi constituída de 35 enfermeiros (n), que atuam na assistência direta ao paciente crítico nas quatro UTIs de um hospital de urgências de no estado de Goiás: 62,9% afirmam que nunca participaram de educação continuada sobre transfusão sanguínea, 68,6 % desconhecem a classificação das reações transfusionais quanto ao tempo de manifestação do quadro clínico. 37,1% apresentaram resposta satisfatória quanto a iniciar a transfusão de concentrado de hemácias de acordo com o percentual de perda volêmica no choque hemorrágico. Considerações finais: Os enfermeiros não têm os conhecimentos necessários para realizar de forma competente o ato transfusional, podendo comprometer a segurança do paciente e a qualidade do serviço de saúde. Parte das fragilidades podem estar relacionadas à formação acadêmica, já que, uma parcela considerável de profissionais relataram não ter cursado disciplina que abordasse a hemoterapia durante a graduação. Espera-se que esse trabalho possa contribuir com o conhecimento e desenvolvimento de estudos sobre a terapia transfusional e que possa servir de base para formulação de avaliação e treinamentos dos profissionais envolvidos na terapia transfusional


Nursing professionals play a key role in transfusion safety. The performance of the nursing team is not limited to just administering the blood components, since it has the responsibility to provide assistance free of damage resulting from malpractice, negligence and recklessness. Therefore, these professionals must be aware of good practices related to the production cycle of blood and components, ensuring the quality of processes and products, reducing health risks and ensuring transfusion safety. Objective: Evaluate nurses´knowledge about blood transfusion, exploring the main points of the legislation that addresses the blood cycle, emphasizing mainly the necessary knowledge during the transfusion act. Methodology: This is an exploratory, cross-sectional, quantitative, descriptive study, carried out in a reference hospital in emergency and trauma in the state of Goiás, with data collection structured through a semi-structured questionnaire, covering the following topics: legislation on the subject, ABO and RH system, collection bag, administration time, immediate and late adverse reaction. Results: The sample consisted of 35 nurses (n), who work in direct assistance to critical patients in the four ICUs of hospital de emergency in the state of Goiás: 62.9% claim that they have never participated in continuing education on blood transfusion, 68.6% are unaware of classification of transfusion reactions according to the time of manifestation of the clinical condition. 37.1% had a satisfactory response regarding initiating the transfusion of packed red blood cells according to the percentage of volume loss in hemorrhagic shock. Final considerations: Nurses do not have the necessary knowledge to competently perform the transfusion act, which may compromise patient safety and the quality of the health service. Part of the weaknesses may be related to academic training, since a considerable portion of professionals reported not having taken a course that addressed hemotherapy during graduation. It is hoped that this work can contribute to the knowledge and development of studies on transfussion therapy and that it can serve as a basis for the formulation of evaluation and training of professionals involved in transfusion therapy

ABSTRACT

Abstract Objective To describe the clinical results of patients admitted and managed as cases of placenta accreta spectrum (PAS) at a Central American public hospital and the influence of the prenatal diagnosis on the condition. Materials and Methods A retrospective analysis of PAS patients treated at Hospital Bertha Calderón Roque, in Managua, Nicaragua, between June 2017 and September 2021. The diagnostic criteria used were those of the International Federation of Gynecology and Obstetrics (Fédération Internationale de Gynécologie et d'Obstétrique, FIGO, in French). The population was divided into patients with a prenatal ultrasonographic diagnosis of PAS (group 1) and those whose the diagnosis of PAS was established at the time of the caesarean section (group 2). Results During the search, we found 103 cases with a histological and/or clinical diagnosis of PAS; groups 1 and 2 were composed of 51 and 52 patients respectively. Regarding the clinical results of both groups, the patients in group 1 presented a lower frequency of transfusions (56.9% versus 96.1% in group 2), use of a lower number of red blood cell units (RBCUs) among those undergoing transfusions (median: 1; interquartile range: [IQR]: 0-4 versus median: 3; [IQR]: 2-4] in group 2), and lower frequency of 4 or more RBCU transfusions (29.4% versus 46.1% in group 2). Group 1 also exhibited a non-significant trend toward a lower volume of blood loss (1,000 mL [IQR]: 750-2,000 mL versus 1,500 mL [IQR]: 1,200-1,800 mL in group 2), and lower requirement of pelvic packing (1.9% versus 7.7% in group 2). Conclusion Establishing a prenatal diagnosis of PAS is related to a lower frequency of transfusions. We observed a high frequency of prenatal diagnostic failures of PAS. It is a priority to improve prenatal detection of this disease.

ABSTRACT

ABSTRACT Introduction: The Zika Virus (ZIKV) is a single-stranded RNA genome virus, belonging to the family Flaviviridae, genus Flavivirus. Outbreaks around the world have demonstrated that the presence of asymptomatic viremic blood donors provides an increase in the risk of transfusion transmission (TT) and nucleic acid test (NAT) screening has been proposed to ensure the blood safety. This study implemented an "in-house" method to detect ZIKV RNA in blood sample donations. Methods: Primary plasma tubes are submitted to nucleic acid extraction on an automated platform. After extraction, the NAT set-up is performed in the robotic pipettor, in which an amplification mixture containing primers and probes for ZIKV and Polio vaccine virus (PV) are added in duplex as an internal control. The real-time polymerase chain reaction is then performed in a thermocycler, using the protocol established by the supplier. Results: From May 2016 to May 2018, 3,369 samples were collected from 3,221 blood donors (confidence coefficient 95%), of which 31 were considered false positive (0.92%), as they did not confirm initial reactivity when repeated in duplicates and 14 (0.42%) had their results invalid due to repeat failure in the internal control, 4 (0.12%), due to insufficient sample volume and 2 (0.05%), due to automatic pipettor failures. No Zika RNA reactive sample was identified. Conclusion: The test showed feasible to be incorporated into the blood screening routine. Our data do not indicate the need to screen for ZIKV RNA in São Paulo during the evaluated period. However, a generic NAT system covering a group of flaviviruses which are circulating in the region, such as DENV and YFV, among others, could be a useful tool.
