However, blood is scarce and costly, and its use is associated with risks. Therefore, the medical professionals who handle it should have adequate knowledge to ensure rational and safe utilization. The objective of the study was to determine the level of BT knowledge among junior medical doctors in Kenya. Methodology: A cross-sectional study was conducted among junior medical doctors working in Western Kenya. Data was collected using questionnaires from August 2021 to March 2022, and analysis was done by way of descriptive and inferential statistics. A p Results: A total of 150 medical doctors participated in the study. Males comprised 60% (n = 90), and the mean age of the participants was 29.9 (SD 3.6) with a range of 25 - 45 years. The mean knowledge score was 54.1% ± 16.4% and was associated with orientation (AOR = 3.157, 95% CI = 1.194 - 8.337). Conclusion: Blood transfusion knowledge among the doctors was suboptimal and was associated with pre-internship induction. There is a need for additional education in BT during all phases of medical training and practice, including orientation for medical interns.展开更多

As a high-risk activity, it necessitates the implementation of specific methods for effective control. The safety of blood transfusion is significantly influenced by the beliefs of healthcare workers and organizational factors, constituting two major considerations. We conducted a cross-sectional, descriptive, and analytical survey to examine the knowledge and practices related to transfusion among the medical and paramedical staff at the Pediatric Department (Mother-Child) of CHU Mohammed VI from September 1, 2022, to December 31, 2022. Among the 135 staff members interviewed, only 41% had received training in blood transfusion. A majority (65.2%) of the staff noted that a mismatch in cross-matching led to transfusion complications. Two-thirds (66.7%) identified chills as the primary clinical sign of potential accidents. Regarding elements to monitor during a reaction, hemolysis (78.5%) and temperature (76.3%) were most commonly mentioned. Surprisingly, more than half (53.3%) of the personnel interviewed did not conduct post-transfusion monitoring. This survey highlighted significant deficiencies in knowledge and practices related to transfusion. To address these issues, we recommend implementing guidelines and providing tailored training for the staff, aiming to rectify these deficiencies and enhance overall practices.展开更多

The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.展开更多

This study aims to explore the effect of timely blood transfusion on the effect and prognosis of blood transfusion in children during the COVID-19 pandemic. Methods: This retrospective cohort study included children who were indicated for blood transfusion in the Pediatric Emergency Department of Guangzhou Women and Children’s Medical Center between January 2020 and December 2020. The outcomes were the effect and the final clinical outcomes of blood transfusion. Results: This study included 260 children with non-traumatic non-surgical low Hb: 209 with timely transfusion, 40 with delayed transfusion, and 11 without transfusion;80% of children were below 60 g/L (min 17 g/L), and the waiting time for transfusion within 100.5 hours (P Conclusions: During the 100-h waiting time, there were no significant differences in outcomes among the timely, delayed, and no transfusion groups. A timely blood transfusion may not affect the clinical outcomes of children.展开更多

These risks have sparked an ongoing debate regarding the overall impact of transfusions on patient outcomes. Thus, this study aimed to evaluate the impact of Red Blood Cells (RBCs) and/or platelet transfusion on the infection incidence and overall survival in AHSCT patients. Methods: We performed a retrospective analysis of clinical and laboratory data of sixty adult patients with primary malignant hematological disorder who had undergone AHSCT. Participants’ data were categorized into two groups;Group 1 (low transfusion group) consisted of patients receiving 10 units. Quantitative data were expressed as mean ± SD. The t-test of significance and Chi-square (χ2) test were used, with p ≤ 0.05 considered significant. Result: A total of 60 patients’ data was included. In Group 1, out of 30 patients, 13 (43.33%) developed infections. In contrast, Group 2 had 21 (70%) out of 30 patients develop infections. Group 1 had a higher survival rate (57.8%) than Group 2 (transfusion > 10 units) (46.2%) with a chi-square value = 23.56, and p-value Conclusion: The volume of blood product transfusions has a considerable impact on patient outcomes, particularly infection and survival rates. Additional long-term prospective studies and larger randomized controlled trials are needed to strengthen the evidence for determining transfusion protocols for these patients.展开更多

Our objective was to investigate the predictive value of the recently updated ACEF Ⅱ score concerning perioprative blood transfusion in adult patients undergoing cardiac surgery. Methods A retrospective review was conducted involving adults(≥18 years) who underwent cardiac surgery for heart disease between January 2019 and June 2019. The primary outcome measure was perioperative blood transfusion among adult patients. Multivariable logistic regression and receiver operation characteristic(ROC) analysis were applied to analyze the link between the ACEF Ⅱ score and perioperative blood transfusion. Results A total of 415 patients were included, participants were stratified into three groups based on their ACEF Ⅱ scores level: ACEF Ⅱ <0.666, 0.666 ≤ ACEF Ⅱ <0.950, and 0.950 ≤ ACEF II ≤4.781. Multivariable Logistic regression analysis indicated that a high ACEF Ⅱ score(OR: 3.59, 95% CI: 1.68-7.67, P<0.001) was independently associated with an increased risk of perioperative blood transfusion among adults undergoing cardiac surgery. Furthermore, the area under the receiver operating characteristic curve for predicting perioperative blood transfusion risk using the ACEF Ⅱ score was found to be 0.607. The Pearson correlation coefficient showed a direct and statistically significant positive correlation between ACEF Ⅱ score and perioperative blood transfusion(r=0.17, P<0.001). Conclusions In conclusion, our findings suggested that the ACEF Ⅱ score possessed significant predictive value regarding related to perioperative blood transfusions during cardiac surgical procedures in adult patients. The higher the ACEF Ⅱ score, the higher incidence of perioperative blood transfusions.展开更多

However, the potential risk associated with allogeneic blood transfusion has heightened interest in the use of autologous blood transfusion. In the present study, the serum concentrations of neopterin, interferon-gamma (IFN-γ), T lymphocyte subsets (CD3^+, CD4^+, CD8^+, CD4^+/CD8^+) and a possible association between these variables were investigated. The purpose was to further evaluate the effect of autologous versus allogeneic blood transfusion on immunological status in patients undergoing surgery for gastric cancer. Methods: Sixty ASA Ⅰ~Ⅱ(American Society of Anesthesiologists) patients undergoing elective radical resection for stomach cancer were randomly allocated to receive either allogeneic blood transfusion (n=30) or autologous blood transfusion (n=30). Serum concentrations of the neopterin, IFN-γ and T lymphocyte subsets in the recipients were measured before induction of anesthesia, after operation, and on the 5th postoperative day. Results: Both two groups, serum neopterin, IFN-γ, percentages of T-cell subsets (CD3^+, CD4^+), and CD4^+/CD8^+ ratio had significantly decreased after operation, but decreased more significantly in group H (receiving allogeneic blood transfusion) than those in group A (receiving autologous whole blood transfusion) (P〈0.05). On the 5th postoperative day,serum neopterin, IFN-γ, CD3^+, CD4^+ T-cells, and CD4^+/CD8^+ ratio returned to the baseline values in group A. In contrast, the above remain decreasing in group H, where there were no significant relations between serum neopterin and IFN-γ. Conclusion:Perioperative surgical trauma and stress have an immunosuppressive impact on gastric cancer patients. Allogeneic blood transfusion exacerbates the impaired immune response. Autologous blood transfusion might be significantly beneficial for immune-compromised patients in the perioperative period, clearly showing its superiority over allogeneic blood transfusion.展开更多

Even if there is clear evidence of transfusion-induced immunosuppression, it is difficult to demonstrate that transfusion is the only determinant factor that decisively affects the outcome. In any case there are several motivations to reduce the practice of blood transfusion. The advantages and drawbacks of different transfusion alternatives are reviewed here, emphasizing that surgeons and anesthetists who practice in centers with a high volume of liver resections, should be familiar with all the possible alternatives.展开更多

HIT can cause devastating thrombosis, making it one of the most serious adverse drug reactions encountered in clinical practice. We successfully treated a case of severe HIT presenting with thrombosis and life-threatening bleeding complications with intravenous immunoglobulin(IVIG), platelet transfusion and oral anticoagulant Rivaroxaban. In this case, we considered that IVIG played the most important role by preventing further thrombosis, increasing the platelet count, and ensuring the efficacy of Rivaroxaban. We therefore suggest that IVIG might be the optimal treatment for patients with this urgent condition.展开更多

We investigated how often these alloimmunization events occur. The transfusions of any D-negative patients were investigated in the First Affiliated Hospital of Xi'an Jiaotong University Medical College, China, during the entire 2009. The antigens of D, C, c, E, and e were routinely serotyped. The "Asian type" DEL variant was genotyped and the RHD heterozygote was determined through two published methods. The changes in anti-D levels were monitored by the indirect antiglobulin test (IAT) and flow cytometry. Thirty D-negative transfused patients were included in the study. We focused on 11 recipients who were transfused with packed red blood cells (RBCs) from DEL donors at least one time. Of those 11 recipients, seven were anti-D negative before transfusion and four were anti-D positive (one patient with an autoantibody). One of the seven pre-transfusion anti-D negative patients produced a primary-response anti-D after being transfused with 400 ml of DEL blood twice. All four pre-transfusion antibody positive patients were not observed hemoglobin (Hb) levels increased, as expected after transfusions. Two patients had an increase in anti-D from 1:8 to 1:64 by IAT, which was also shown by flow cytometry. None of the patients experienced an acute hemolytic episode. Our data indicated that the primary anti-D induced by DEL transfusion or the secondary anti-D elevated by DEL in a truly D-negative patient might not be unusual. We suggest that a truly D-negative childbearing-aged woman should avoid DEL transfusion to protect her from primary anti-D allosensitization. In addition, anti-D positive recipients should also avoid DEL red cell transfusion due to the delayed hemolytic transfusion reaction (DHTR).展开更多

However, because of the risk of reinfusion of salvaged blood contaminated by tumor cells, the use of IBSA in hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT) is controversial. The critical points include whether tumor cells can be cleared by IBSA, whether IBSA increases the risk of recurrence or metastasis, and what are the indications for IBSA. Moreover, is it warranted to take the risk of tumor dissemination by using IBSA to avoid allogeneic blood transfusion? Do the remaining tumor cells after additional filtration by leukocyte depletion filters still possess potential tumorigenicity? Does IBSA always work well? We have reviewed the literature and tried to address these questions. The available data indicate that IBSA is safe in LT for HCC, but randomized, controlled and prospective trials are urgently required to clarify the uncertainty.展开更多

METHODS: The proportion of patients who received HT was compared between two groups determined by the time of AT introduction; period A (1991-1994, n = 93) and period B (1995-2000, n = 201). Multivariate logistic regression analysis was performed in order to identify independent significant predictors of the need for HT. We also investigated the impact of AT and HT on long-term postoperative outcome after curative surgery for HCC. RESULTS: The proportion of patients with HT was significantly lower in period B than period A (18.9% vs 60.2%, P < 0.0001). Multivariate logistic regression analysis identified AT administration as a significant independent predictor of the need for HT (P < 0.0001). Disease-free survival in patients with AT was comparable to that without any transfusion. Multivariate analysis identified HT administration as an independent significant factor for poorer disease-free survival (P = 0.0380). CONCLUSION: AT administration significantly decreased the need for HT.

文摘BACKGROUND Transfusion transmissible infections(TTIs)are illnesses spread through contaminated blood or blood products.In India,screening for TTIs such as hepatitis B virus(HBV),hepatitis C virus(HCV),human immunodeficiency virus(HIV)-I/II,malaria,and syphilis is mandatory before blood transfusions.Worldwide,HCV,HBV,and HIV are the leading viruses causing mortality,affecting millions of people globally,including those with co-infections of HIV/HCV and HIV/HBV.Studies highlight the impact of TTIs on life expectancy and health risks,such as liver cirrhosis,cancer,and other diseases in individuals with chronic HBV.Globally,millions of blood donations take place annually,emphasizing the importance of maintaining blood safety.AIM To study the prevalence of TTIs,viz.,HBV,HCV,HIV I/II,syphilis,and malaria parasite(MP),among different blood donor groups.METHODS The study assessed the prevalence of TTIs among different blood donor groups in Delhi,India.Groups included total donors,in-house donors,total camp donors,institutional camp donors,and community camp donors.Tests for HIV,HBV,and HCV were done using enzyme-linked immunosorbent assay,while syphilis was tested with rapid plasma reagins and MP rapid card methods.The prevalence of HBV,HCV,HIV,and syphilis,expressed as percentages.Differences in infection rates between the groups were analyzed usingχ²tests and P-values(less than 0.05).RESULTS The study evaluated TTIs among 42158 blood donors in Delhi.The overall cumulative frequency of TTIs in total blood donors was 2.071%,and the frequencies of HBV,HCV,HIV-I/II,venereal disease research laboratory,and MP were 1.048%,0.425%,0.221%,0.377%,and 0.0024%,respectively.In-house donors,representing 37656 donors,had the highest transfusion transmissible infection(TTI)prevalence at 2.167%.Among total camp donors(4502 donors),TTIs were identified in 1.266%of donors,while community camp donors(2439 donors)exhibited a prevalence of 1.558%.Institutional camp donors(2063 donors)had the lowest TTI prevalence at 0.921%.Statistical analysis revealed significant differences in overall TTI prevalence,with total and in-house donors exhibiting higher rates compared to camp donors.CONCLUSION Ongoing monitoring and effective screening programs are essential for minimizing TTIs.Customizing blood safety measures for different donor groups and studying socio-economic-health factors is essential to improving blood safety.
文摘Background: Blood transfusion (BT) is crucial to the provision of modern health care. However, blood is scarce and costly, and its use is associated with risks. Therefore, the medical professionals who handle it should have adequate knowledge to ensure rational and safe utilization. The objective of the study was to determine the level of BT knowledge among junior medical doctors in Kenya. Methodology: A cross-sectional study was conducted among junior medical doctors working in Western Kenya. Data was collected using questionnaires from August 2021 to March 2022, and analysis was done by way of descriptive and inferential statistics. A p Results: A total of 150 medical doctors participated in the study. Males comprised 60% (n = 90), and the mean age of the participants was 29.9 (SD 3.6) with a range of 25 - 45 years. The mean knowledge score was 54.1% ± 16.4% and was associated with orientation (AOR = 3.157, 95% CI = 1.194 - 8.337). Conclusion: Blood transfusion knowledge among the doctors was suboptimal and was associated with pre-internship induction. There is a need for additional education in BT during all phases of medical training and practice, including orientation for medical interns.

文摘BACKGROUND There is an ongoing debate regarding the relationship between intraoperative blood transfusions and patient outcomes.Unifying the results is difficult because of differences in surgery type,target population and postoperative observation indicators.AIM To evaluate the risk factors for intraoperative blood transfusion and its impact on postoperative outcomes in elderly gastrointestinal cancer patients.METHODS This was a retrospective single-center study of elderly patients(≥65 years old)who underwent elective abdominal surgery for gastrointestinal cancer with general anesthesia.Patients with chronic kidney disease and missing related data were excluded.The primary outcomes included acute kidney injury(AKI),myocardial injury,and respiratory complications during hospitalization.Multivariate logistic regression was performed to explore the exposure-outcome relationship.RESULTS A total of 967 patients were included in this study.A lower preoperative hematocrit level,longer operative time(>300 minutes)and greater amount of blood loss were observed in 145(15.0%)patients who received blood transfusions during surgery(P<0.0005).Among these patients,the incidences of AKI,myocardial injury and respiratory complications were 8.3%(n=12),5.5%(n=8),and 15.9%(n=23),respectively,and these values were significantly greater.Multivariate analysis revealed that receiving a transfusion was an independent risk factor for AKI,myocardial injury and respiratory complications(all P<0.05).CONCLUSION These results demonstrate that intraoperative blood transfusion increases the risk of poorer outcomes in elderly patients receiving gastrointestinal cancer surgery.These findings provide new ideas for improving the prognosis of elderly cancer patients.
文摘The Rh blood group system,especially the D antigen,is crucial in transfusion medicine and obstetrics.Weak D phenotypes,caused by mutations in the Rhesus D antigen(RhD)blood group(RHD)gene,result in reduced antigen expression,posing challenges in serological testing and clinical management.Variability in detection methods leads to inconsistent results,making accurate classification difficult.Molecular techniques like polymerase chain reaction and DNA sequencing have significantly improved the identification of weak D variants,offering more reliable transfusion strategies and reducing the risk of alloimmunization.However,challenges such as lack of standardized protocols,cost constraints,and population-specific variations remain.In obstetrics,proper management of pregnant women with weak D is essential to prevent hemolytic disease of the fetus and newborn.Non-invasive prenatal testing using cell-free fetal DNA shows promise in predicting RhD incompatibility and minimizing unnecessary Rh immune globulin administration.Future advancements in highthroughput genotyping and discovery of novel RHD alleles could enhance RhD testing accuracy and efficiency.Standardizing RHD genotyping and adopting genotype-based management strategies for Rh immune globulin therapy and red blood cell transfusions will improve patient safety and clinical outcomes.This review examines the molecular basis,challenges,and future prospects in weak D phenotype management.
文摘Blood transfusion is a complex activity, involving many actors. As a high-risk activity, it necessitates the implementation of specific methods for effective control. The safety of blood transfusion is significantly influenced by the beliefs of healthcare workers and organizational factors, constituting two major considerations. We conducted a cross-sectional, descriptive, and analytical survey to examine the knowledge and practices related to transfusion among the medical and paramedical staff at the Pediatric Department (Mother-Child) of CHU Mohammed VI from September 1, 2022, to December 31, 2022. Among the 135 staff members interviewed, only 41% had received training in blood transfusion. A majority (65.2%) of the staff noted that a mismatch in cross-matching led to transfusion complications. Two-thirds (66.7%) identified chills as the primary clinical sign of potential accidents. Regarding elements to monitor during a reaction, hemolysis (78.5%) and temperature (76.3%) were most commonly mentioned. Surprisingly, more than half (53.3%) of the personnel interviewed did not conduct post-transfusion monitoring. This survey highlighted significant deficiencies in knowledge and practices related to transfusion. To address these issues, we recommend implementing guidelines and providing tailored training for the staff, aiming to rectify these deficiencies and enhance overall practices.
文摘BACKGROUND The advent of coronavirus disease 2019(COVID-19)unveiled the worst national blood crisis that the United States had witnessed in over a decade.With the pandemic influencing the different stages of the acquisition of blood products outside the hospital setting,we aimed to explore the possible barriers contributing to the shortage of blood products within the medical community.the COVID era and pre-COVID era.METHODS We conducted a retrospective cross-sectional study on hospitalized patients distinguishing the pattern of blood transfusion during the COVID and pre-COVID era in a community hospital.Data was tabulated to include the number of red blood cell(RBC)transfusions and if transfusions met restrictive blood transfusion criteria as per institutional guidelines.Chi-square was applied to test the statistical association between qualitative variables.Unpaired t test and Mann Whitney U test were applied respectively to test the mean difference of quantitative variables.RESULTS A total of 208 patients were included in the study,of which 108 were during COVID era and 100 were during pre-COVID era.The leading reason for admission in both the COVID era and pre-COVID era transfused patients was shortness of breath(53.7%and 36%P=0.001),followed by gastrointestinal bleeding(25.9%and 21%P=0.001).There was a higher percentage of RBC transfusions in the intensive care unit in the COVID-era group than in the pre-COVID era group(38.9%vs 22%,P=0.008).The restrictive transfusion criteria were met in 62%vs 79%in the COVID and pre-COVID eras,respectively(P=0.008).CONCLUSION The COVID-era group received RBC transfusions with less stringent adherence to restrictive blood transfusion practices in comparison to pre-COVID era group.
文摘BACKGROUND Cesarean hemorrhage is one of the serious complications,and short-term massive blood transfusion can easily cause postoperative infection and physical stress response.However,predictive nursing intervention has important clinical significance for it.AIM To explore the effect of predictive nursing intervention on the stress response and complications of women undergoing short-term mass blood transfusion during cesarean section(CS).METHODS A clinical medical record of 100 pregnant women undergoing rapid mass blood transfusion during sections from June 2019 to June 2021.According to the different nursing methods,patients divided into control group(n=50)and observation group(n=50).Among them,the control group implemented routine nursing,and the observation group implemented predictive nursing intervention based on the control group.Moreover,compared the differences in stress res-ponse,complications,and pain scores before and after the nursing of pregnant women undergoing rapid mass blood transfusion during CS.RESULTS The anxiety and depression scores of pregnant women in the two groups were significantly improved after nursing,and the psychological stress response of the observation group was significantly lower than that of the control group(P<0.05).The heart rate and mean arterial pressure(MAP)of the observation group during delivery were lower than those of the control group,and the MAP at the end of delivery was lower than that of the control group(P<0.05).Moreover,different pain scores improved significantly in both groups,with the observation group considerably less than the control group(P<0.05).After nursing,complications such as skin rash,urinary retention,chills,diarrhea,and anaphylactic shock in the observation group were 18%,which significantly higher than in the control group(4%)(P<0.05).CONCLUSION Predictive nursing intervention can effectively relieve the pain,reduce the incidence of complications,improve mood and stress response,and serve as a reference value for the nursing of women undergoing rapid mass transfusion during CS.
文摘Objective: To develop and internally validate a nomogram to predict recurrence-free survival (RFS) including the time to radical cystectomy (RC) and perioperative blood transfusion (PBT) as potential predictors.Methods: Patients who underwent open RC and ileal conduit between January 1996 to December 2016 were split into developing (n=948) and validating (n=237) cohorts. The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.
文摘Background: The COVID-19 pandemic has led to a shortage of blood supplies for children, resulting in prolonged waiting times for transfusions. This study aims to explore the effect of timely blood transfusion on the effect and prognosis of blood transfusion in children during the COVID-19 pandemic. Methods: This retrospective cohort study included children who were indicated for blood transfusion in the Pediatric Emergency Department of Guangzhou Women and Children’s Medical Center between January 2020 and December 2020. The outcomes were the effect and the final clinical outcomes of blood transfusion. Results: This study included 260 children with non-traumatic non-surgical low Hb: 209 with timely transfusion, 40 with delayed transfusion, and 11 without transfusion;80% of children were below 60 g/L (min 17 g/L), and the waiting time for transfusion within 100.5 hours (P Conclusions: During the 100-h waiting time, there were no significant differences in outcomes among the timely, delayed, and no transfusion groups. A timely blood transfusion may not affect the clinical outcomes of children.
文摘Background: While blood product transfusion is essential for managing hematologic deficits in Allogenic Hematopoietic stem cell transplant (AHSCT) recipients, it has risks including infectious disease transmission, alloimmunization, and transfusion reactions. These risks have sparked an ongoing debate regarding the overall impact of transfusions on patient outcomes. Thus, this study aimed to evaluate the impact of Red Blood Cells (RBCs) and/or platelet transfusion on the infection incidence and overall survival in AHSCT patients. Methods: We performed a retrospective analysis of clinical and laboratory data of sixty adult patients with primary malignant hematological disorder who had undergone AHSCT. Participants’ data were categorized into two groups;Group 1 (low transfusion group) consisted of patients receiving 10 units. Quantitative data were expressed as mean ± SD. The t-test of significance and Chi-square (χ2) test were used, with p ≤ 0.05 considered significant. Result: A total of 60 patients’ data was included. In Group 1, out of 30 patients, 13 (43.33%) developed infections. In contrast, Group 2 had 21 (70%) out of 30 patients develop infections. Group 1 had a higher survival rate (57.8%) than Group 2 (transfusion > 10 units) (46.2%) with a chi-square value = 23.56, and p-value Conclusion: The volume of blood product transfusions has a considerable impact on patient outcomes, particularly infection and survival rates. Additional long-term prospective studies and larger randomized controlled trials are needed to strengthen the evidence for determining transfusion protocols for these patients.
文摘Background The age, creatinine levels, and the ejection fraction Ⅱ score(ACEF Ⅱ score) are significant indicators for assessing inflammation and predicting adverse outcomes following cardiac surgery. Our objective was to investigate the predictive value of the recently updated ACEF Ⅱ score concerning perioprative blood transfusion in adult patients undergoing cardiac surgery. Methods A retrospective review was conducted involving adults(≥18 years) who underwent cardiac surgery for heart disease between January 2019 and June 2019. The primary outcome measure was perioperative blood transfusion among adult patients. Multivariable logistic regression and receiver operation characteristic(ROC) analysis were applied to analyze the link between the ACEF Ⅱ score and perioperative blood transfusion. Results A total of 415 patients were included, participants were stratified into three groups based on their ACEF Ⅱ scores level: ACEF Ⅱ <0.666, 0.666 ≤ ACEF Ⅱ <0.950, and 0.950 ≤ ACEF II ≤4.781. Multivariable Logistic regression analysis indicated that a high ACEF Ⅱ score(OR: 3.59, 95% CI: 1.68-7.67, P<0.001) was independently associated with an increased risk of perioperative blood transfusion among adults undergoing cardiac surgery. Furthermore, the area under the receiver operating characteristic curve for predicting perioperative blood transfusion risk using the ACEF Ⅱ score was found to be 0.607. The Pearson correlation coefficient showed a direct and statistically significant positive correlation between ACEF Ⅱ score and perioperative blood transfusion(r=0.17, P<0.001). Conclusions In conclusion, our findings suggested that the ACEF Ⅱ score possessed significant predictive value regarding related to perioperative blood transfusions during cardiac surgical procedures in adult patients. The higher the ACEF Ⅱ score, the higher incidence of perioperative blood transfusions.
文摘Objective:To study the effect of the direct anti-human globulin test on the clinical efficacy of blood transfusion patients.Methods:52 transfused patients were selected for this study,of which 26 cases with positive direct anti-human globulin tests were included in the positive group,and another 26 cases with negative direct anti-human globulin tests were included in the negative group.The apparent efficacy of the patients in the two groups after blood transfusion was compared.Results:After blood transfusion,the apparent efficacy of the negative group was significantly higher,P<0.05;in the positive group,the proportion of the predominantly multi-antibody group was the highest;after blood transfusion,the post-transfusion apparent efficacy of the simple IgG group was higher than that of the multi-antibody group,P<0.05;comparing the intensity of the different antibodies resulted in the 1+group,and the 3+to 4+groups were significantly lower after blood transfusion,P<0.05.Conclusion:The use of the direct antiglobulin test in transfused patients showed that patients with positive results would have better clinical efficacy.Direct anti-human globulin tests will have an impact on the clinical efficacy of blood transfusion in patients with positive results,so it is very important to carry out a direct anti-human globulin test on blood transfusion patients.
文摘Blood loss during liver transplantation (OLTx) is a common consequence of pre-existing abnormalities of the hemostatic system,portal hypertension with multiple collateral vessels,portal vein thrombosis,previous abdominal surgery,splenomegaly,and poor "functional" recovery of the new liver.The intrinsic coagulopathic features of end stage cirrhosis along with surgical technical difficulties make transfusion-free liver transplantation a major challenge,and,despite the improvements in understanding of intraoperative coagulation profiles and strategies to control blood loss,the requirements for blood or blood products remains high.The impact of blood transfusion has been shown to be significant and independent of other well-known predictors of posttransplant-outcome.Negative effects on immunomodulation and an increased risk of postoperative complications and mortality have been repeatedly demonstrated.Isovolemic hemodilution,the extensive utilization of thromboelastogram and the use of autotransfusion devices are among the commonly adopted procedures to limit the amount of blood transfusion.The use of intraoperative blood salvage and autologous blood transfusion should still be considered an important method to reduce the need for allogenic blood and the associated complications.In this article we report on the common preoperative and intraoperative factors contributing to blood loss,intraoperative transfusion practices,anesthesiologic and surgical strategies to prevent blood loss,and on intraoperative blood salvaging techniques and autologous blood transfusion.Even though the advances in surgical technique and anesthetic management,as well as a better understanding of the risk factors,have resulted in a steady decrease in intraoperative bleeding,most patients still bleed extensively.Blood transfusion therapy is still a critical feature during OLTx and various studies have shown a large variability in the use of blood products among different centers and even among individual anesthesiologists within the same center.Unfortunately,despite the large number of OLTx performed each year,there is still paucity of large randomized,multicentre,and controlled studies which indicate how to prevent bleeding,the transfusion needs and thresholds,and the "evidence based" perioperative strategies to reduce the amount of transfusion.

文摘Background: Allogeneic blood transfusion-induced immunomodulation (TRIM) and its adverse effect on the prognosis of patients treated surgically for cancer remain complex and controversial. However, the potential risk associated with allogeneic blood transfusion has heightened interest in the use of autologous blood transfusion. In the present study, the serum concentrations of neopterin, interferon-gamma (IFN-γ), T lymphocyte subsets (CD3^+, CD4^+, CD8^+, CD4^+/CD8^+) and a possible association between these variables were investigated. The purpose was to further evaluate the effect of autologous versus allogeneic blood transfusion on immunological status in patients undergoing surgery for gastric cancer. Methods: Sixty ASA Ⅰ~Ⅱ(American Society of Anesthesiologists) patients undergoing elective radical resection for stomach cancer were randomly allocated to receive either allogeneic blood transfusion (n=30) or autologous blood transfusion (n=30). Serum concentrations of the neopterin, IFN-γ and T lymphocyte subsets in the recipients were measured before induction of anesthesia, after operation, and on the 5th postoperative day. Results: Both two groups, serum neopterin, IFN-γ, percentages of T-cell subsets (CD3^+, CD4^+), and CD4^+/CD8^+ ratio had significantly decreased after operation, but decreased more significantly in group H (receiving allogeneic blood transfusion) than those in group A (receiving autologous whole blood transfusion) (P〈0.05). On the 5th postoperative day,serum neopterin, IFN-γ, CD3^+, CD4^+ T-cells, and CD4^+/CD8^+ ratio returned to the baseline values in group A. In contrast, the above remain decreasing in group H, where there were no significant relations between serum neopterin and IFN-γ. Conclusion:Perioperative surgical trauma and stress have an immunosuppressive impact on gastric cancer patients. Allogeneic blood transfusion exacerbates the impaired immune response. Autologous blood transfusion might be significantly beneficial for immune-compromised patients in the perioperative period, clearly showing its superiority over allogeneic blood transfusion.
文摘Allogeneic blood transfusion during liver resection for malignancies has been associated with an increased incidence of different types of complications: infectious complications, tumor recurrence, decreased survival. Even if there is clear evidence of transfusion-induced immunosuppression, it is difficult to demonstrate that transfusion is the only determinant factor that decisively affects the outcome. In any case there are several motivations to reduce the practice of blood transfusion. The advantages and drawbacks of different transfusion alternatives are reviewed here, emphasizing that surgeons and anesthetists who practice in centers with a high volume of liver resections, should be familiar with all the possible alternatives.
文摘Heparin-induced thrombocytopenia(HIT) is a relatively infrequent complication of heparin administration. HIT can cause devastating thrombosis, making it one of the most serious adverse drug reactions encountered in clinical practice. We successfully treated a case of severe HIT presenting with thrombosis and life-threatening bleeding complications with intravenous immunoglobulin(IVIG), platelet transfusion and oral anticoagulant Rivaroxaban. In this case, we considered that IVIG played the most important role by preventing further thrombosis, increasing the platelet count, and ensuring the efficacy of Rivaroxaban. We therefore suggest that IVIG might be the optimal treatment for patients with this urgent condition.

文摘Previously, both primary and secondary anti-D alloimmunizations induced by "Asian type" DEL (RHD1227A allele) were observed in two incidents. We investigated how often these alloimmunization events occur. The transfusions of any D-negative patients were investigated in the First Affiliated Hospital of Xi'an Jiaotong University Medical College, China, during the entire 2009. The antigens of D, C, c, E, and e were routinely serotyped. The "Asian type" DEL variant was genotyped and the RHD heterozygote was determined through two published methods. The changes in anti-D levels were monitored by the indirect antiglobulin test (IAT) and flow cytometry. Thirty D-negative transfused patients were included in the study. We focused on 11 recipients who were transfused with packed red blood cells (RBCs) from DEL donors at least one time. Of those 11 recipients, seven were anti-D negative before transfusion and four were anti-D positive (one patient with an autoantibody). One of the seven pre-transfusion anti-D negative patients produced a primary-response anti-D after being transfused with 400 ml of DEL blood twice. All four pre-transfusion antibody positive patients were not observed hemoglobin (Hb) levels increased, as expected after transfusions. Two patients had an increase in anti-D from 1:8 to 1:64 by IAT, which was also shown by flow cytometry. None of the patients experienced an acute hemolytic episode. Our data indicated that the primary anti-D induced by DEL transfusion or the secondary anti-D elevated by DEL in a truly D-negative patient might not be unusual. We suggest that a truly D-negative childbearing-aged woman should avoid DEL transfusion to protect her from primary anti-D allosensitization. In addition, anti-D positive recipients should also avoid DEL red cell transfusion due to the delayed hemolytic transfusion reaction (DHTR).
文摘Intraoperative blood salvage autotransfusion (IBSA) is used in various surgical procedures. However, because of the risk of reinfusion of salvaged blood contaminated by tumor cells, the use of IBSA in hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT) is controversial. The critical points include whether tumor cells can be cleared by IBSA, whether IBSA increases the risk of recurrence or metastasis, and what are the indications for IBSA. Moreover, is it warranted to take the risk of tumor dissemination by using IBSA to avoid allogeneic blood transfusion? Do the remaining tumor cells after additional filtration by leukocyte depletion filters still possess potential tumorigenicity? Does IBSA always work well? We have reviewed the literature and tried to address these questions. The available data indicate that IBSA is safe in LT for HCC, but randomized, controlled and prospective trials are urgently required to clarify the uncertainty.
文摘AIM: To evaluate the significance of autologous blood transfusion (AT) in reducing homologous blood transfusion (HT) in surgery for hepatocellular carcinoma (HCC). METHODS: The proportion of patients who received HT was compared between two groups determined by the time of AT introduction; period A (1991-1994, n = 93) and period B (1995-2000, n = 201). Multivariate logistic regression analysis was performed in order to identify independent significant predictors of the need for HT. We also investigated the impact of AT and HT on long-term postoperative outcome after curative surgery for HCC. RESULTS: The proportion of patients with HT was significantly lower in period B than period A (18.9% vs 60.2%, P < 0.0001). Multivariate logistic regression analysis identified AT administration as a significant independent predictor of the need for HT (P < 0.0001). Disease-free survival in patients with AT was comparable to that without any transfusion. Multivariate analysis identified HT administration as an independent significant factor for poorer disease-free survival (P = 0.0380). CONCLUSION: AT administration significantly decreased the need for HT. Considering the postoperative survival disadvantage of HT, AT administration could improve the long-term outcome of HCC patients.
