Recognition of whole blood transfusion in civilian trauma resuscitation / 中国输血杂志

There has been a growing amount of evidence that a balanced blood component transfusion with roughly equal ratio of units of packed red blood cells, fresh frozen plasma, and platelets leads to better outcomes in massive transfusion resuscitation of trauma victims. Therefore, the great interest of massive transfusion protocol (MTP) with whole blood was aroused. Low titer group O whole blood (LTOWB) is implemented in routine use for civilian prehospital ambulance services in large trauma centers of most European and American countries nowadays. There is a growing body of evidence to date to support that early use of LTOWB in patients with life-threatening bleeding improve their survival. In view of the current situation of whole blood supply in our country, most trauma resuscitation guidelines still recommend balanced component transfusion for MTPs in the early stage of resuscitation. The research and application of LTOWB abroad will be introduced in this article.

The present situation and advance of red blood cell transfusion triggers / 中国输血杂志

In clinical practice, red blood cell infusion needs to be based on the patient′s hemoglobin level. However, different guidelines recommend different thresholds for red blood cell infusion and the timing of blood transfusion initiation is still controversial due to the presence of these different thresholds. Meanwhile, the use of allogeneic blood products carries a certain risk of transfusion-related infections or organ damage. Therefore, initiating red blood cell infusion requires more evidence. This review discusses some new methods, namely central venous oxygen saturation, arterial venous oxygen difference, near-infrared spectroscopy, and perioperative transfusion trigger score. It aims to help evaluate blood transfusion trigger and provide reference for doctors when making transfusion decisions.

Desafíos en el manejo del sarcoma de Ewing en una paciente testigo de Jehová / Challenges in the care of Ewing's sarcoma in a Jehovah's Witness patient

El sarcoma de Ewing es una neoplasia de hueso y tejidos blandos, cuyo manejo se relaciona con toxicidad hematológica. Este aspecto representa un desafío médico y ético en los pacientes testigos de Jehová quienes, por sus creencias religiosas, rechazan la aplicación de hemoderivados, con riesgo de que se descontinúe la quimioterapia o de que se utilicen dosis subóptimas. Se presenta el caso de una mujer colombiana de 34 años, testigo de Jehová, con diagnóstico de sarcoma de Ewing con estadificación clínica IIB (T1N0M0) en las regiones maxilar y mandibular izquierdas, tratada con quimioterapia, quien presentó un valor mínimo de hemoglobina de hasta 4,5 g/dl y tuvo indicación quirúrgica como parte del tratamiento. En estos pacientes, la decisión de practicar una transfusión comprende implicaciones éticas que requieren alternativas terapéuticas y un abordaje multidisciplinario.

Ewing's sarcoma is a bone and soft tissue neoplasm, whose management is related to hematological toxicity. This aspect represents a medical and ethical challenge in Jehovah's Witnesses patients, who, due to their religious beliefs, reject the blood component transfusion, with the risk of discontinuing chemotherapy or using suboptimal doses. We present the case of a 34-year-old Colombian woman, Jehovah's Witness, diagnosed with Ewing's sarcoma with clinical stage IIB (T1N0M0) in the left maxillary and mandibular regions, treated with chemotherapy, who presented a hemoglobin nadir of up to 4.5 g/dL, and surgical indication as part of the treatment. In these patients, the transfusion decision has ethical implications that require therapeutic alternatives and a multidisciplinary approach.

Analysis of blood component transfusion and some adverse reactions in myelodysplastic syndroms patients / 中国输血杂志

【Objective】 To analyze the blood transfusion and adverse reactions in myelodysplastic syndroms (MDS) patients, so as to improve transfusion management in MDS patients. 【Methods】 The diagnosis and treatment information of MDS patients with blood transfusion in our hospital from January 2003 to December 2022 were collected, and the component transfusion and adverse reactions were investigated. 【Results】 The average infusion volume of red blood cells(RBCs) and platelets were respectively (27.46±43.11 ) and (16.41±24.81 ) in 799 MDS patients, which had no correlation with gender and blood type. The incidence of adverse reactions was 18.27% (146/799), with the most common adverse reactions as delayed serologic transfusion reaction (DSTR) (9.01%, 72/799), followed by non hemolytic fever reaction (4.76%, 38/799) and allergic reaction (4.38%, 35/799). Compared with all patients with transfusion, DSTR was more common in females (P<0.05), with elder age and had more RBCs consumption (all P<0.01). 86.11%(62/72) were Rh system, and 40.28% (29/72) had 2 or more antibodies. The occurrence time of DSTR in some patients was not related to the volume of RBCs trans infusion. 【Conclusion】 MDS patients, with more average transfusion volume and higher incidence of adverse reactions especially DSTR, were recommended a strictly limited transfusion schedule and Rh phenotype matching RBC products. The investigation of immune status of MDS patients at different periods is helpful to provide new aspects and therapeutic measures for the pathogenesis of DSTR, and the antibody screening time may adjusted appropriately.

Profile of hemotherapy care and the safety of the transfusion process

SUMMARY OBJECTIVE: This study aimed to evaluate the safety of the transfusion process in a public teaching hospital and to outline the profile of the hemotherapy care provided. METHODS: This was an exploratory, descriptive, and prospective study with a quantitative approach and grounded in field research. Data were obtained from medical and nursing records and active search. RESULTS: Concentrated red blood cells were the most transfused blood component. Inadequate indications of blood components were detected in 15% of Concentrated red blood cells transfusions, 20% of fresh plasma, 29.2% of platelet concentrates, and 36.4% of cryoprecipitates. Filling out the blood component request forms, the nursing checklist and the entry book were inadequate in 88.3, 92.8, and 69.5% of the procedures, respectively. CONCLUSIONS: Faults were identified throughout the transfusion process, revealing inadequate compliance with current standards and legislation, essential in minimizing the occurrence of errors and maximizing the safety of transfusion. Studies of this nature reinforce the need for continued research in this field.

Adverse reactions to blood transfusion: A retrospective analysis of 814 cases in Qingdao area from 2020 to 2021 / 中国输血杂志

【Objective】 To investigate the incidence and composition of adverse reactions to blood transfusion(ARBT) in Qingdao hospitals in recent years. 【Methods】 The "Statistical Table of Adverse Reactions to Blood Transfusion in Medical Institutions" issued by Qingdao Quality Control Center of Blood Transfusion throughout 2020 to 2021, involving 96 hospitals in the region, were collected and analyzed, including the number, proportion and types of ARBT, as well as the types of blood components transfused. 【Results】 From 2020 to 2021, 296 676 cases of blood transfusion in 96 hospitals occurred, and the incidence of ARBT was 0.27% (814/296 676), of which the incidence of ARBT involving plasma transfusion was 0.17% [accounting for 39.07% (318/814) of all transfusion reactions], involving platelet transfusion was 0.68% [31.08% (259/814)], involving erythrocyte transfusion was 0.11% [27.64% (225/814)] and cryoprecipitation transfusion 0.03% [1.47% (12/814)]. The types of ARBT were anaphylaxis 77.64% (632/814), fever 19.78% (161/814), transfusion-related dyspnea 1.47% (12/814), transfusion-related circulatory overload 0.37% (3/814), purpura 0.25% (2/814) and transfusion-related hypotension 0.25% (2/814), delayed hemolysis 0.12%(1/814) and acute hemolysis 0.12%(1/814), respectively. 【Conclusion】 In recent years, the incidence of ARBT in local medical institutions is lower than that of domestic general level, and the main reactions are anaphylaxis and fever following the transfusion of plasma or (and) platelets.The monitoring and control of ARBT should be strengthened in each hospital with accurate and timely report, and active preventive measures should be taken to control or reduce the incidence of ARBT effectively.

Study on the ratio of blood transfusion components in disseminated intravascular coagulation caused by sever postpartum hemorrhage / 中国输血杂志

【Objective】 To investigate the transfusion ratio of plasma to RBC suspension during DIC caused by sever postpartum hemorrhage, so as to improve the clinical blood transfusion protocol. 【Methods】 A total of 82 parturients, who gave birth in our obstetrics department from January 2008 to December 2019 and treated successfully for DIC due to sever postpartum hemorrhage, were selected for the study. According to the plasma/RBC suspension ratio range (from 0.4 to 2.0) during DIC rescue, the included population was divided into four groups according to the ratio interval of 0.4: Group 1: 0.4~0.8 (13 people, median 0.7), Group 2 : 0.8~1.2(30 people, median 1.0), Group 3: 1.2~1.6(30 people, median 1.3), and Group 4: 1.6~2.0 (9 people, median 1.8). The general conditions, way of delivery, number of uterine artery perfusion embolization and surgical operations performed in the 4 groups were recorded. Once spontaneous postpartum hemorrhage occurred, blood cell analysis and coagulation function examinations were carried out every 1 to 2 hours until the condition was stable. The 24-hour blood loss, transfusion units of RBC suspension, fresh frozen plasma(FFP), platelet apheresis and fibrinogen during DIC and throughout the rescue of 4 groups were recorded and compared. Locally Weighted Regression (Lowess) method was applied to analyze the nonlinear association between the plasma/RBC suspension ratio and the duration of DIC, according to the duration of DIC in 4 groups. 【Results】 1) The shortest duration of DIC (326.15 min) was observed in DIC patients transfused with a plasma/ red blood cell suspension ratio=1.8. The duration of DIC (min) in the four groups were 505.21±259.53, 435.67±307.18, 420.93±259.43, and 247.86±215.77, respectively (P<0.05). 2) The coagulation indexes PT(s), INR, APTT(s) and Fib(g/L) gradually recovered between 2.9~13.9 h after transfusion in all four groups, especially in group 4 (median plasma/RBC suspension ratio of 1.8), whose changes were most pronounced in PT, INR, and Fib at 4.3 h, 2.9 h, and 5 h, respectively (P<0.05). 【Conclusion】 Fresh frozen plasma should be given as early as possible during blood transfusion treatment of DIC rescue. The increase of the ratio of plasma/RBC suspension is beneficial to the early recovery of DIC, and the optimal ratio of plasma to RBC suspension is 1.8.

【Objective】 To retrospectively investigate the clinical transfusion status in Tibet Autonomous Region People′s Hospital, in order to provide data basis for further improvement of the rational and scientific blood use in our hospital. 【Methods】 Medical records of transfusion recipients in our hospital from 2014 to 2018 were investigated via HIS system, and such indicators as total clinical blood use, usage of whole blood and blood components, blood transfusion per capita, usage of blood components with different types. and the usage of red blood cells and plasma in each clinical department were retrospectively analyzed. 【Results】 The total clinical blood usage of our hospital increased from 3 930.5 U in 2014 to 4 949 U in 2018, with an annual growth rate of 5.93%. The average blood use per capita in 2014 and 2018 was 0.205 U vs 0.218 U, and incidence of blood component transfusion was 47.18% vs 99.02% The proportion of blood component (red blood cell and plasma) usage was 36.0%, 35.9%, 20.7% and 7.4% for blood type O, A, B and AB, respectively. The usage of total blood, red blood cell and plasma in internal and surgical departments were 13 883.8 U vs 7 080.8 U, 4 963.3 U vs 3 647.3 U and 6 055 U vs 1 170 U, respectively. 【Conclusion】 The total clinical blood usage and the proportion of blood component transfusion in our hospital is increasing year by year. Therefore, rational and scientific blood use should be further improved.

Analysis of influencing factors for transfusion inperioperative extracorporeal membrane oxygenation supported lung transplantation recipients / 中华器官移植杂志

Objective:To evaluate perioperative coagulatory parameters and transfusion rates of lung transplantation recipients.Methods:Clinical data were retrospectively reviewed for 178 lung transplant recipients at China-Japan Friendship Hospital from March 2017 to July 2019. According to whether extracorporeal membrane oxygenation(ECMO)was used during perioperative period, they were divided into two groups of ECMO(131 cases)and without ECMO(47 cases). Clinical data, laboratory examinations and blood transfusion status of two groups were compared. In ECMO group, excluding secondary thoracotomy for hemostasis(7 cases)and incomplete data(2 cases), the remainders were divided into the groups of no red blood cell transfusion(63 cases), red blood cell transfusion(59 cases), plasma transfusion <1 000 ml(99 cases)and plasma transfusion≥1 000 ml (23 cases), no platelet transfusion(93 cases)and platelet transfusion(29 cases). Clinical data, laboratory examinations and ECMO-related parameters of recipients were analyzed by Bary Logistic regression.Results:Statistically significant inter-group differences existed in body mass index(BMI), disease course, primary disease, bilateral lung transplantation, laboratory examinations, postoperative blood transfusion volume, postoperative red blood cell and plasma transfusion ratio between groups with and without ECMO( P<0.05). Bilateral lung transplantation, ASA grade, differences in BMI, disease course, postoperative hemoglobin<100 g/L, postoperative PT/APTT/INR abnormalities and postoperative PLT count <100×10 9/L were independent risk factors for postoperative transfusion during ECMO. Conclusions:The application of ECMO during lung transplantation may affect the perioperative transfusion volume and demand.Fully assessing blood transfusion requirements, optimizing coagulation monitoring and identifying the independent influencing factors of postoperative blood transfusion facilitate clinical scientific and rational blood transfusions.

Role of blood and blood components transfusion in obstetric emergencies

Background: Common obstetric emergencies require blood and blood components transfusion. The use of blood and its components has become a lifesaving strategy in management of obstetric haemorrhage. This study was aimed to know the prevalence, indications and adverse reactions of blood and its components transfusion.Methods: A review of 405 patients of obstetric emergencies requiring blood and its component transfusion was done.Results: Prevalence of blood and blood components transfusion in obstetric emergencies in one-year period was 18.4%. Mostly women who received blood transfusions were multiparous (50.12%) and belonged to rural areas (62%). Anemia is a risk factor for obstetric emergencies and the mean pre transfusion hemoglobin ±SD was 8.04±1.38 (g/dl). Obstetric hemorrhage (68.6%) was the most common indication for transfusion and packed red cells were most commonly (54.07%) transfused. The overall percentage of adverse reactions seen during transfusion was 1.95%.Conclusions: The present study reinforces the importance of appropriate use of blood and its components in obstetric emergencies. Appropriate use of blood components avoids many of the hazards associated with use of whole blood. All blood components should be made available at peripheral hospitals as most of the patients require specific blood component and they are referred to tertiary care centre in emergencies which can be avoided.

Hemovigilance and patient safety: analysis of immediate transfusion reactions in elderly / Hemovigilancia y seguridad del paciente: análisis de reacciones de transfusión inmediata en ancianos / Hemovigilância e segurança do paciente: análise de reações transfusionais imediatas em idosos

ABSTRACT Objective: To identify immediate transfusion reactions in elders hospitalized in a public hospital in the Federal District. Methods: This is an observational, retrospective, documental, and analytical research, with a quantitative analysis of 516 transfusions of packed red blood cells in elders hospitalized in the largest public hospital, who required blood components, from June to December 2017, through descriptive statistics. Results: The sample corresponded to 46.36% of the total number of transfusions in elders in the period. The mean age was 70 years old. There were adverse effects (reactions to the transfusion) in 12 (2.3%) transfusions. Respiratory alterations (33.3%) and fever (23.8%) were the most common events. Conclusion: The incidence of reactions to the transfusion is below national and international rates, indicating probable undernotification, which could be associated to a lack of knowledge regarding its clinical manifestations and the lack of systematic monitoring of the transfusion.

Hemocomponentes en urgencias: tratamiento vital para los pacientes politraumatizados / Blood products in the emergency room: vital treatment for polytraumatized patients

Introducción: La principal causa de mortalidad temprana en pacientes politraumatizados es la hipovolemia secundaria a hemorragia masiva. La terapia con hemocomponentes y cristaloides constituye un mecanismo esencial y salvavidas en estas situaciones como medida de reemplazo de volumen. De la misma manera los pacientes con lesiones traumáticas graves tienen una disminución aguda significativa en el recuento de plaquetas circulantes que los hace candidatos a la transfusión de componentes plaquetarios; sin embargo, el uso de estos componentes sanguíneos puede traer consigo desenlaces no deseados como aumento en la mortalidad. Si bien muchos estudios revelan un aumento de la mortalidad como desenlace asociado al uso de hemocomponentes, otros establecen su uso como una medida reductora de este desenlace. Objetivo: Exponer las principales indicaciones de hemocomponentes en los pacientes politraumatizados, así como relacionar los eventos adversos asociados a su uso que influyen sobre la mortalidad y el tiempo de hospitalización de estos pacientes. Desarrollo: La mortalidad asociada al uso de hemocomponentes aún es un tema controvertido. En la hemorragia masiva el apoyo transfusional rápido y eficiente es esencial en el tratamiento y la atención de politraumatismos, de ahí que sea necesario contar con protocolos de transfusión que mejoren los resultados y disminuyan las complicaciones. Además, se identificó la necesidad de nuevos estudios sobre el tema para mejorar estos protocolos y reducir las complicaciones.(AU)

Introduction: The main cause of early mortality in polytrauma patients is hypovolemia secondary to massive hemorrhage. Hemocomponent and crystalloid therapy is an essential and life-saving mechanism in these situations as a measure of volume replacement. In the same way, patients with severe traumatic injuries have a significant acute decrease in circulating platelet counts that makes them candidates for transfusion of platelet components; However, the use of these blood components can lead to unwanted outcomes such as increased mortality. Although many studies reveal an increase in mortality as an outcome associated with the use of blood components, others establish its use as a reducing measure of this outcome. Objective: to present the main indications of blood components in polytrauma patients, as well as to relate the adverse events associated with their use that influence the mortality and hospitalization time of these patients. Devlopment: Mortality associated with the use of blood components is still a controversial issue. In massive hemorrhage, rapid and efficient transfusion support is essential in the treatment and care of polytrauma, hence it is necessary to have transfusion protocols that improve results and reduce complications. In addition, the need for new studies on the subject to improve these protocols and reduce complications was identified(AU)

Effect of exchange transfusion therapy on complications and prognosis in newborns with bilirubin encephalopathy / 中国基层医药

Objective To study the influence of exchange transfusion therapy on the complications and prognosis in newborns with bilirubin encephalopathy.Methods From June 2013 to June 2016,76 children with bilirubin encephalopathy in Feicheng People's Hospital were selected and divided into study group(n =41) and control group(n =35) according to whether or not accepted the exchange transfusion treatment.The levels of total bilirubin (TBIL),indirect bilirubin(IBIL),direct bilirubin(DBIL) and the ratio of total bilirubin to plasma albumin(B/A)were detected and compared between the two groups.The complications and prognosis of the two groups were recorded.Results After exchange transfusion,the TBIL,IBIL,DBIL and B/A values in the study group were (209.49 ± 48.82) μmol/L,(201.81 ± 39.62) μmoL/L,(21.92 ± 19.47) μmoL/L and (5.15 ± 1.89),respectively,which were significantly lower than those before exchange transfusion [(492.35 ± 42.41) μmol/L,(439.44 ± 52.56) μmol/L,(69.38 ± 21.56) μmol/L and (13.28 ± 0.40)] (t =28.007,23.117,10.461,26.947,all P ＜ 0.05).The incidence rates of anemia,sinus bradycardia and electrolyte disturbances in the study group were 48.78％,48.78,60.98％,respectively,which were significantly higher than those in the control group(17.14％,14.29％,14.29％) (x2 =8.397,10.178,17.228,all P ＜ 0.05).The incidence rates of death,hearing impairment and brain damage in the study group were 7.32％,70.73％ and 12.20％,respectively,which in the control group were 11.43％,71.43％ and 14.29％,respectively,there were no statistically significant differences between the two groups (x2 =0.382,0.004,0.072,all P ＞ 0.05).Conclusion Exchange transfusion can significantly reduce the levels of bilirubin and B/A in the treatment of newborns with bilirubin encephalopathy,but it can increase the incidence rate of anemia,sinus bradycardia and electrolyte disturbances,which has no significant influence on the prognosis of patients.

Prognostic effect of different blood transfusion ratios in trauma patients with massive transfusion / 中华创伤杂志

Objective To evaluate the prognostic effect of different ratios of fresh frozen plasma (FFP) to packed red blood cells (PRBC) in massively transfused trauma patients.Methods A retrospective cohort study was conducted for 210 trauma patients who received more than 10 units of PRBC during the initial 24 hours from January 2007 to June 2015.The patients were divided into four groups:Group A(PRBC:FFP ≤1,n=41),GroupB (1 ＜PRBC:FFP≤1.5,n=63),GroupC(1.5＜PRBC:FFP≤2,n=30) and Group D (PRBC:FFP ＞2,n =76).At 24 hours after admission,blood transfusion amount,blood transfusion ratios,post-transfusion adverse reactions (allergy,non-hemolytic febrile transfusion reaction,hemolysis,congestive heart failure,pulmonary edema,etc) and coagulation changes [hemoglobin (Hb),platelet count (PC),prothrombin time(PT),activated partial thromboplastin time(APTT),international normalized ratio (INR),etc] were compared among groups.Prognostic markers including sequential organ failure assessment(SOFA),hospital stay,ICU stay,30-day mortality and causes of death were also evaluated.Results Use of PRBC was decreased significantly in Group A than in other groups (P ＜ 0.01),and there were no differences in blood transfusion adverse reactions among all groups (P ＞ 0.05).The coagulation indices (PT,APTT and INR) in Groups A and B were significantly decreased compared to Group D after transfusion (P ＜ 0.05).There were no differences in length of hospital stay and ICU stay among all groups (P ＞ 0.05).Group D was associated with higher SOFA and higher 30-day mortality than other groups(P ＜0.01),but no differences were found in Group A,B and C (P ＞0.05).Meanwhile,ratio of patients died of massive hemorrhage in Group D was also higher than other groups (P ＜0.01).Kaplan-Meier survival analysis showed the survival interval was the shortest in Group D,while the longest in Group B and C.Conclusions Modest transfusion ratios (1.5 ＜ PRBC:FFP ≤2)within 24 hours can substantially improve outcomes in trauma patients.Aggressive ratios may improve coagulation indices and reduce use of PRBC,with no more benefit to the outcomes.
