ABSTRACT
Background: Blood transfusion holds utmost importance in comprehensive obstetric care and Gynaecology. The present study has been done to evaluate the indications of blood transfusion in the Obstetrics and Gynaecology Department. Methods: The retrospective observational study was conducted between April 2023 to April 2024 in Department of Obstetrics and Gynaecology, Government Medical College, Saharanpur. Results: A total of 257 units of Blood was transfused between April 2023 to April 2024 in Obstetrics and Gynaecology Department. 60.6% transfusion were in age group 21-30 years. 48.26% transfusion were in hemoglobin 7-9 gm/dl. Most common blood group transfused was B positive 40.79% and 85.2% transfusion were packed red blood cell, 84.07% had single unit blood transfusion, 57.25% had transfusion for anemia in pregnancy, 36.84% transfusion were for abnormal uterine bleeding. Conclusions: Prevalence of anemia in reproductive age group is an important reason for blood transfusion in obstetrics and gynaecology. Hence emphasis should be to treat anemia through drugs to reduce unnecessary transfusion especially single unit transfusion.
ABSTRACT
The Bombay blood group is a rare blood type, predominantly found in regions with a high prevalence of consanguineous marriages due to its autosomal recessive inheritance pattern. This blood group is unique because individuals lack the H antigen, a precursor to the A and B antigens found in other blood types, making their blood type exceptionally rare. Managing antenatal patients with the Bombay blood group presents significant challenges, especially in cases of anaemia or any instance of blood loss. The primary difficulty arises from the scarcity of compatible blood for transfusion, as individuals with the Bombay blood group can only receive blood from other Bombay group donors. This rarity complicates the management of potential complications during pregnancy, labour, and delivery. To address these challenges, minimizing blood loss is essential during all stages of pregnancy, particularly during labour, Caesarean sections, and in the prevention of postpartum haemorrhage. Effective management requires a multidisciplinary approach, involving obstetricians, haematologists, and blood bank services. One potential strategy to mitigate the risk of blood shortages is autologous blood transfusion. This option can be particularly valuable during pregnancy; however, it requires careful consideration of the potential risks and benefits. The procedure should be conducted under the guidance of healthcare professionals experienced in managing such cases, ensuring the safety and well-being of both the mother and the foetus. In our case report, we present an antenatal patient with anaemia and the challenges encountered during the antenatal and postnatal periods. This case highlights the complexities of managing pregnancies involving the Bombay blood group. It underscores the importance of a well-coordinated, multidisciplinary approach to optimize outcomes for both mother and child.
ABSTRACT
Although blood is the essence of life, and is one of the most precious donations; blood transfusion services are facing shortage of blood all over the world. A significant percentage of people have false beliefs about blood donation. Increase in the level of knowledge and correction of false beliefs should be the top most priority. Therefore, studying factors contributing to their knowledge, attitude and practice of blood donation is essential. There are studies that investigated the effectiveness of interventions or procedure changes in blood donation settings on outcomes including donor deferral, disclosure of risk factors, and rates of errors and omissions. Researchers also identified several interventions to improve donor compliance that have been tested in blood donation settings and provided evidence for the effectiveness of computerized interviews in improving detection of risk factors. Interventions can utilize the processes of change (POC) measure to guide stage matched interventions to encourage use of relevant experiential and behavioral strategies to increase blood donation. Interventions to recruit and retain blood donors in the general population have been classified into five approaches: motivational, reminders/asking, measurement of cognitions, incentives, and preventing vasovagal reactions. Effective recruitment and retention are two different processes and may require different approaches. For example, retention may be influenced more by interventions that focus on actions during or after donation rather than interventions prior to the blood donation appointment.
ABSTRACT
Background: Total knee replacement is one of the common orthopaedic procedures performed worldwide. Blood transfusion is one of the major requirements in TKR procedure due to the amount of blood loss during and after the procedure. We carried out a prospective study to determine the efficacy of tranexamic acid in controlling blood loss during TKR procedure. Methods: Study was conducted at a tertiary care centre, involving cases operated by a single surgeon. Study included 140 patients undergoing primary TKR for advance degenerative disease of knee and were divided into two groups of 70 each, one group that received tranexamic acid before surgery and another group that did not receive tranexamic acid before surgery. Patient with allergy to the drug, hepato/renal dysfunction, DVT, abnormal PT and INR were not included. Tranexamic acid was given intravenously as well as intra-articular. Results: Pre-operative haemoglobin ranged from 10.2 gm% to 14.4 gm% in the group getting tranexamic acid and from 10% to 14 % in the group not getting tranexamic acid. Post operatively haemoglobin varied from 8.4 gm% to 12.8 gm% in Group 1 and from 7.8 gm% to 12 gm% in Group 2. Difference of mean post-operative Hb (p=0.0045) and PCV (p=0.0024) in two groups was statistically significant. Conclusions: We concluded that administration of tranexamic acid reduces the blood loss as well as need of blood transfusion in a patient undergoing total knee replacement.
ABSTRACT
Anemia is frequent in preterm infants. Red blood cell transfusion practices vary between different centers. The objective of this study was to review red blood cell transfusion practices in preterm infants between 2020 and 2021. This was a narrative review that included studies published on PubMed (Medline) and Web of Science between October 2020 and October 2021. Ten studies were included finally. Red blood cell transfusion frequency was variable. Some neonatal units did not report transfusion protocols. Most studies reported volumes of 10-15 ml/kg per transfusion. The implementation of an anemia care bundle and adoption of restrictive transfusion resulted in a reduction in the number of transfusions, the volume transfused, and a reduction in the rate of multiple transfusions. We suggest that neonatal units that care for preterm infants should have a transfusion protocol based on the best evidence available and this issue may improve.
A anemia é frequente nos bebês prematuros. As práticas de transfusão de glóbulos vermelhos variam entre os diferentes hospitais. O objetivo deste estudo foi revisar as práticas de transfusão de glóbulos vermelhos em bebês prematuros entre 2020 e 2021. Esta foi uma revisão narrativa que incluiu estudos publicados no PubMed (Medline) e Web of Science entre outubro de 2020 e outubro de 2021. Dez estudos foram definitivamente incluídos. A frequência de transfusão de glóbulos vermelhos foi variável. Algumas unidades neonatais não relataram protocolos de transfusão. A maioria dos estudos relatou volumes de 10-15 ml/kg por transfusão. A implantação de um conjunto de cuidados para anemia e a adoção de transfusão restritiva resultaram em uma redução do número de transfusões, do volume transfundido e uma redução na taxa de transfusões múltiplas. Sugerimos que as unidades neonatais que prestam cuidados a bebês prematuros devem ter um protocolo de transfusão baseado em evidências para que todo esse problema melhore.

The management of preterm babies are usually challenging with one significant issue being anaemia, which often requires multiple blood transfusions and their associated complications. Delayed cord clamping during delivery have been identified as a proactive measure to reduce the need for multiple blood transfusion in preterm babies. We present three case series of preterm babies delivered and managed with intentional delayed cord clamping [DCC], to strengthen the advocacy for the practice particularly in developing and less developed nations where blood transfusion facilities and practice may be inadequate.
ABSTRACT
Background: The Bombay blood group, a rare type often confused with 慜�, poses a critical transfusion risk, requiring specific compatibility with Bombay (Oh) blood. With a lack of data in Bangladesh, this study aimed to establish a comprehensive database for the rare Bombay phenotype, crucial for transfusion safety. Objective was to determine the frequency prevalence of Bombay phenotype among 慜� blood group individuals. Methods: A cross-sectional study conducted at Bangabandhu Sheikh Mujib Medical University from January 2020 to June 2021 involved, aseptic collection of 3 ml venous blood sample, with forward and reverse blood grouping revealing a 慜� phenotype. Utilizing anti-H lectin resolved discrepancies and confirmed the absence of 慔� antigen in individuals with Bombay blood groups. Blood samples of Bombay phenotype individuals showed the following reactions: anti-A (-), anti-B (-), anti-AB (-), anti-H (-), A cells 4+, B cells 4+, O cells 4+. Results: Among 10,000 individuals with apparent blood group 慜�, 99.97% were identified as 慜� blood type, while only 0.03% exhibited the rare Bombay blood group. ABO and Rh-D blood group frequencies varied over the study period, with B +ve at the highest (28.31%) and AB -ve at the lowest (0.21% to 0.23%). Overall, O +ve had the highest frequency (97.29%), and Bombay blood group was rare, with 慜� dominating at 99.97%. Conclusions: The study identified a 0.03% prevalence of the Bombay phenotype. Due to its potential confusion with 慜� blood group, transfusing 慜� blood to Bombay individuals carries a substantial risk of severe hemolytic reactions, including fatal consequences.
ABSTRACT
Background: Blood transfusion is a life-saving intervention. Blood should be accepted from non-remunerated and healthy donors. Proper donor screening procedure minimizes the risk of transfusion transmitted Infections and also wastage of blood and blood products and thus screening of donors is a prerequisite for blood donation. Methods: This is a retrospective study conducted in blood bank center in the Department of Pathology in a Government teaching hospital, Shivamogga from January 2022 to June 2022. All the voluntary and replacement donors were evaluated by the standard questionnaire and medical examination including demographic profile, anthropometry, blood group, vital signs and hemoglobin estimated by cyanmethemoglobin method were collected from the donation requisition forms and online deferred list. The data were represented in the form of percentage, descriptive statistics and analysed. Results: Out of 3,449 blood donors, 252 were deferred. The deferral rate was 7.31%. Among the ineligible donors, males 245 (97.22%) outnumbered females 7 (2.8%). 242 donors (96.03%) were temporarily rejected among which high blood pressure constituted to 23.02% followed by alcohol consumption (11.11%) whereas 10 donors (3.96%) were deferred permanently. 9 donors (3.57%) had low haemoglobin level. Conclusions: Temporary deferrals are more than permanent deferrals thus temporarily deferred donors should be instructed to return for blood donation after their period of deferral days to retain the pool of blood donors.

Background: The pregnant uterus has one of the greatest blood supplies than any other organ in the body. When uterus is surgically opened to perform caesarean section, a number of large blood vessels are cut. While the average blood loss for a vaginal birth is about 500cc, the average blood loss with caesarean section is almost double and may require blood transfusion. This study identified frequency of the blood transfusion among the patients undergoing caesarean section with various indications. The aim of this study was to ascertain the frequency of blood transfusions among patients undergoing Caesarean sections with various indications. Material & Methods: This cross-sectional study and was conducted in the Department of Obstetrics & Gynaecology of Bangabandhu Seikh Mujib Medical University (BSMMU) Hospital, Dhaka, Bangladesh during the period from September 2012 to February 2013. Results: In this study a total 96 caesarean sections were observed, the mean age of the patients was 29.88 � 3.14 years. About 26.04% of patients required blood transfusion, with different indications of cesarean sections including placenta praevia (83.33%), malpresentation (66.66%), obstructed labor (33.33%), and previous caesarean section (18.75%). Only 4% of transfused patients experienced a mild febrile reaction. Conclusions: Frequency of blood transfusion was high (26.04%) during caesarean sections. Preoperative anaemia, quantitity of blood loss and various indications of caesarean sections were the considering factors for the blood transfusions during caesarean sections. Placenta praevia was the most common indications of blood transfusion during caesarean sections. Efforts should be made to reduce the blood transfusion without increasing maternal morbidity and mortality to reduce hazard of blood transfusions blood born infections, like HBV, HCV & HIV infections that are more prevalent in developing countries like ours.
ABSTRACT
Background: Placenta Accreta Spectrum Disorder (PAS) is a complex obstetric condition with significant implications for maternal and fetal health. The study aims to provide a comprehensive understanding of the maternal and fetal outcomes associated with PAS in a tertiary care hospital in Bangladesh. Material & Methods: This prospective observational study was conducted at a tertiary care hospital in Bangladesh over 18 months. The study included 60 pregnant women diagnosed with PAS, adhering to specific inclusion and exclusion criteria. Data were collected through structured questionnaires and analyzed using SPSS version 26. Results: The majority of participants was aged between 21-30 years (76.67%) and had completed their Higher Secondary Certificate (HSC) (50%). Regular antenatal care was reported by 50% of the participants. Hemorrhage was observed in 21.67% of the cases, with 36.67% requiring blood transfusion. Maternal outcomes were uneventful in 78.33% of the cases, and fetal outcomes resulted in 90% live births. Conclusions: The study reveals the complex nature of PAS and its significant impact on maternal and fetal health. Despite the high incidence of hemorrhage and the need for blood transfusion, proactive and multidisciplinary management strategies appear to result in a majority of uneventful maternal outcomes. The findings emphasize the need for comprehensive antenatal care and further research to improve outcomes.
ABSTRACT
ABO is the most widely utilized blood group system. Bombay blood group is a rare subtype of autosomal recessive group with absence of H antigen and presence of anti-H, anti-A and anti-B antibodies. We present a case of a 51-year- old lady posted for hemithyroidectomy and incidentally detected to be of Bombay blood group when a blood unit was reserved for surgery. She was a non-secretor for H substance on saliva inhibition test. History of consanguineous marriage was present. We wish to reaffirm that ardent effort has to be undertaken to confirm all 'O' group individuals with reverse grouping during routine testing for blood groups, failing which the rare Bombay blood group can be misdiagnosed as 'O' resulting in an acute haemolytic reaction if any unit other than that of Bombay blood group is transfused. Individuals with this group need to be counselled about rarity and clinical implications of the same.
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.

RESUMEN La anemia fetal es una causa de morbilidad y mortalidad perinatal. Aunque tiene diferentes etiologías y a pesar de la introducción de la profilaxis de inmunoglobulina RhD, la aloinmunización sigue siendo una de sus principales causas. Estos embarazos se identifican inicialmente midiendo en el feto la velocidad sistólica máxima de la arteria cerebral media (MCA-PSV) y se debe sospechar de anemia moderada a grave cuando el MCA-PSV es ≥1,50 múltiplos de la mediana. En estos casos, el hematocrito real se determina obteniendo sangre fetal. La intervención con una hemoglobina fetal no menor a 7 g/dL resulta en un mejor resultado fetal en comparación a esperar hasta el desarrollo de anemia grave < a 5 g/dL o hidrops. La transfusión fetal intravascular es preferible a la transfusión intraperitoneal debido a mayores tasas de supervivencia, particularmente de fetos hidrópicos. La vena umbilical es el sitio vascular preferido debido a la facilidad de acceso y una mayor seguridad en comparación con otros sitios vasculares. La punción cardíaca directa rara vez se realiza debido a un mayor riesgo de complicaciones graves, incluida la muerte fetal. En el presente artículo presentamos el primer caso comunicado en nuestro medio de transfusión intracardiaca en un feto con anemia severa por isoinmunización Rh, el cual tuvo un manejo exhaustivo y difícil, pero con una excelente evolución fetal, neonatal y posnatal.
ABSTRACT Fetal anemia is a cause of perinatal morbidity and mortality. Although it has different etiologies and despite the introduction of RhD immunoglobulin prophylaxis, alloimmunization remains one of its main causes. These pregnancies are initially identified by measuring in the fetus the middle cerebral artery peak systolic velocity (MCA-PSV) and moderate to severe anemia should be suspected when the MCA-PSV is ≥1.50 multiples of the median. In these cases, the actual hematocrit is determined by obtaining fetal blood. Intervention with a fetal hemoglobin no lower than 7g/ dL results in a better fetal outcome compared to waiting until the development of severe anemia <5g/dL or hydrops. Intravascular fetal transfusion is preferable to intraperitoneal transfusion due to higher survival rates, particularly of hydropic fetuses. The umbilical vein is the preferred vascular site due to ease of access and greater safety compared to other vascular sites. Direct cardiac puncture is rarely performed because of an increased risk of serious complications, including fetal death. In the present article we present the first case reported in our country of intracardiac transfusion in a fetus with severe anemia due to Rh isoimmunization, which had an exhaustive and difficult management, but with an excellent subsequent fetal, neonatal and postnatal evolution.
ABSTRACT
【Objective】 To retrospectively analyze the indexes of autologous blood transfusion during heart valve replacement, in order to provide reference for allogeneic blood transfusion during heart valve replacement surgery under direct vision. 【Methods】 The data of 180 patients who underwent heart valve replacement in our hospital from January 2020 to December 2021 were analyzed retrospectively. The patients were divided into allogeneic and non-allogeneic blood transfusion group based on whether allogeneic blood was transfused during the operation, and the general data and 24 hours pre- and post-operative clinical examination indexes were compared. 【Results】 Multivariate logistic regression analysis showed that age (OR=1.110, 95% CI: 1.058-1.165, P<0.05) and intraoperative cardiopulmonary bypass time (OR=1.062, 95% CI: 1.038-1.086, P<0.05) were risk factors for allogeneic blood transfusion, and preoperative Hb content (OR=0.910, 95%CI: 0.868-0.953, P<0.05) was a protective factor. The RBC count(4.16±0.73 vs 4.52±0.71)×1012/L and Hb(120.94±17.97 vs 136.57±19.33) g/L at 24 hours preoperative in the allogeneic transfusion group were lower than those in the non-allogeneic transfusion group, and the RBC(3.51±0.53 vs 4.13±0.78)×1012/L, Hb(114.15±11.68 vs 124.79±14.96)g/L and platelet count(124.28±32.11 vs 148.29±26.62)×109/L at 24 hours postoperative were significantly lower than those in the non-allogeneic transfusion group (P<0.05). 【Conclusion】 Age and intraoperative cardiopulmonary bypass time are the risk factors for autologous and allogeneic blood transfusion during heart valve replacement under direct vision, and the preoperative Hb content is a protective factor. It is necessary to evaluate the symptomatic treatment of patients before operation and reduce allogeneic blood transfusion.
ABSTRACT
【Objective】 To systematically evaluate the safety and efficacy of intraoperative cell salvage (IOCS) for placenta previa women undergoing cesarean section. 【Methods】 The PubMed, Web of Science, Embase, the Cochrane Library of clinical trials, China National Knowledge Infrastructure (CNKI) and Wan Fang databases were searched from inception to September 2022. The standardized mean differences (SMDs) or relative risk (RR) and 95% confidence intervals (CIs) and prediction intervals (PIs) regarding the comparison between the IOCS and allogeneic blood transfusion (ABT) groups were analyzed using R software Version 4.1.2 and Stata Version 12.0. 【Results】 Five RCTs and ten retrospective cohort studies were included in this meta-analysis. Analysis of cohort studies showed that compared with the ABT group, women with placenta previa who underwent IOCS had generally higher postoperative hemoglobin (Hb) (SMD, 0.626; 95% CI: 0.103 to 1.149; 95% PI: -1.320 to 2.572) and hematocrit (Hct) (SMD, 0.617; 95% CI: 0.130 to 1.104; 95% PI: -1.084 to 2.317) levels. In RCTs, we observed that placenta previa women undergoing IOCS were almost 72.7% less likely to suffer from adverse events AEs than the ABT group (RR, 0.273; 95% CI, 0.082 to 0.904). The difference in postoperative prothrombin time (PT), activated prothrombin time (APTT), fibrinogen (Fib) concentration, blood urea nitrogen (BUN) and creatinine (Cr) between the IOCS and ABT group did not reach statistical significance. 【Conclusion】 Women with placenta previa who undergo IOCS have higher postoperative Hb and Hct concentrations compared to those treated with ABT. IOCS has no major effects on postoperative coagulation parameters and renal function parameters. IOCS is associated with a significantly lower risk of transfusion-related AEs among women undergoing cesarean section.
ABSTRACT
The recently officially approved and released health industry standard Standard for Blood Storage(WS 399-2023) by the National Health Commission is the latest revised version of Standard for Blood Storage(WS 399-2012), which mainly stipulates the storage requirements for whole blood, red blood cells, platelets, granulocytes, plasma and irradiated blood. It applies to blood collection and supply institutions and healthcare institutions, and is the guideline for the safe use of blood.
ABSTRACT
【Objective】 To explore the feasibility of blood transfusion compatibility testing for multiple myeloma(MM) patients treated with anti-CD38 monoclonal antibody daratumumab (DARA) after DARA-Fab fragment blocking, and to evaluate the transfusion efficacy by comparing with dithiothreitol(DTT) method. 【Methods】 After DARA was prepared into DARA-Fab fragments using PierceFab preparation kit, the neutralization effects of different volumes (5, 10, 15, 30 μL) on screening cells and panel cells were confirmed. DARA-Fab fragments and screening cells with specific antigens and corresponding monoclonal antibody reagents were used as the experimental group and the control group with the same volume of saline for incubating and centrifugin.Twenty MM patients treated with DARA were selected for cross-matching with DARA-Fab and DTT respectively, and the laboratory indexes before and after transfusion were statistically analyzed, and the two blood matching methods were compared. 【Results】 After incubating and centrifuging, the results of DARA-Fab fragments(15, 30 μL) with screening cells and serum mixed with DARA were negative, while those of DARA-Fab(5, 10 μL) were positive. 15μL DARA-Fab treated antibody identification cells (2, 3, 4, 5, 7, 9, 11) were negative, antibody identification cells (1, 6, 8, 10, 12) were negative after 30 μL DARA-Fab fragments treatment; the results of MNS, Duffy, Kidd, Kell, Lewis, Rh blood group system of the experimental group were consistent with those of the control group; the hemoglobin (Hb) (g/L) of 20 patients after infusion of RBC (73.90±1.90) was significantly higher than that before transfusion (63.60±1.58), P0.05).And no statistical difference was noticed in Hb (10.75±1.04 vs 10.30±0.98), TBil (3.31±1.47 vs 3.31±0.55), DBIL(2.76±1.24 vs 2.60±0.83), and I-Bil(1.97±0.40 vs 2.82±0.53) between the DTT treatment method and the DARA Fab fragment treatment before and after transfusion(P>0.05). 【Conclusion】 DARA-Fab can remove the interference of RBC on cross matching by blocking CD38 antigen. This method has no effect on the antigens of common RBC blood group systems, and shows significant blood transfusion efficacy as that of DTT method.
ABSTRACT
【Objective】 To explore the feasibility of establishing quantifiable evaluation system combined with PDCA in improving blood transfusion medical record. 【Methods】 A working group was set up in our hospital to establish an evaluation system for blood transfusion medical record according to relevant norms and literature. The data from September 2022 to February 2023 were used as the control group, and data from from April to May 2023 as the study group. PDCA was used to analyze the causes for poor quality of medical record. The quality of medical record was continuous improved for two months and the results were analyzed. 【Results】 Comparison between the research group and the control group showed that the score of blood transfusion consent (item A), blood transfusion application (item B), blood transfusion evaluation (item C), blood transfusion serious hazard (item F) increased respectively as 17.50±5.54 vs 21.08±3.75 (P<0.01), 16.22±2.05 vs 17.33±1.85 (P<0.01), 13.05±3.5 vs 14.72±1.97 (P<0.01), 7.9±1.44 vs 8.7±0.92 (P<0.01), and the total score of medical record was 85.36±7.5 vs 93.05±5.04 (P<0.01). The qualified rate of medical record increased from 82.2% to 98.3%(P<0.01). 【Conclusion】 The establishment of quantifiable blood transfusion medical record evaluation system combined with PDCA can help realize timely regulation and standardization of blood transfusion medical record.
ABSTRACT
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.
