J Biomed Inform 2024; 156:104680. [PMID: 38914411 DOI: 10.1016/j.jbi.2024.104680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 05/27/2024] [Accepted: 06/21/2024] [Indexed: 06/26/2024]
Abstract
OBJECTIVE Failure to receive prompt blood transfusion leads to severe complications if massive bleeding occurs during surgery. For the timely preparation of blood products, predicting the possibility of massive transfusion (MT) is essential to decrease morbidity and mortality. This study aimed to develop a model for predicting MT 10 min in advance using non-invasive bio-signal waveforms that change in real-time. METHODS In this retrospective study, we developed a deep learning-based algorithm (DLA) to predict intraoperative MT within 10 min. MT was defined as the transfusion of 3 or more units of red blood cells within an hour. The datasets consisted of 18,135 patients who underwent surgery at Seoul National University Hospital (SNUH) for model development and internal validation and 621 patients who underwent surgery at the Boramae Medical Center (BMC) for external validation. We constructed the DLA by using features extracted from plethysmography (collected at 500 Hz) and hematocrit measured during surgery. RESULTS Among 18,135 patients in SNUH and 621 patients in BMC, 265 patients (1.46%) and 14 patients (2.25%) received MT during surgery, respectively. The area under the receiver operating characteristic curve (AUROC) of DLA predicting intraoperative MT before 10 min was 0.962 (95% confidence interval [CI], 0.948-0.974) in internal validation and 0.922 (95% CI, 0.882-0.959) in external validation, respectively. CONCLUSION The DLA can successfully predict intraoperative MT using non-invasive bio-signal waveforms.

Aoki M, Abe T, Komori A, Katsura M, Matsushima K. Association between whole blood ratio and risk of mortality in massively transfused trauma patients: retrospective cohort study. Crit Care 2024; 28:253. [PMID: 39030579 PMCID: PMC11264807 DOI: 10.1186/s13054-024-05041-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Accepted: 07/16/2024] [Indexed: 07/21/2024] Open
Abstract
BACKGROUND Although whole blood (WB) transfusion was reported to improve survival in trauma patients with hemorrhagic shock, little is known whether a higher proportion of WB is associated with an improved survival. This study aimed to evaluate the association between whole blood ratio (WBR) and the risk of mortality in trauma patients requiring massive blood transfusion. METHODS We performed a retrospective cohort study from the ACS-TQIP between 2020 and 2021. Patients were aged ≥ 18 years and received WB within 4 h of hospital arrival as a part of massive blood transfusion. Study patients were categorized into four groups based on the quartiles of WBR. Primary outcome was 24-h mortality and secondary outcome was 30-day mortality. Multivariable logistic regression analysis, fitted with generalized estimating equations, was performed to adjust for confounding factors and accounted for within-hospital clustering. RESULTS A total of 4087 patients were eligible for analysis. The median age was 37 years (interquartile range [IQR]: 27-53 years), and 85.0% of patients were male. The median number of WB transfusions was 2.3 units (IQR 2.0-4.0 units), and the total transfusion volume was 4940 ml (IQR 3350-8504). When compared to the lowest WBR quartile, the highest WBR quartile had lower adjusted 24-h mortality (adjusted odds ratio [AOR]: 0.61, 95% confidence interval [CI]: 0.46-0.81) and 30-day mortality (AOR 0.58; 95% CI 0.45-0.75). CONCLUSION The probability of mortality consistently decreased with higher WBR in trauma patients requiring massive blood transfusion.

[PMID: 39031656 DOI: 10.1111/vox.13701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 06/03/2024] [Accepted: 06/05/2024] [Indexed: 07/22/2024]
Abstract
BACKGROUND AND OBJECTIVES Massive transfusion protocols (MTPs) are critical in managing haemorrhage, yet their utilization varies. There is lack of data on the utilization of MTPs in the Middle East and North Africa (MENA) region. This study aims to assess the degree of utilization of MTPs in the region. MATERIALS AND METHODS We conducted a survey to collect data on MTP use, inviting medical directors of transfusion services from various hospitals. Data were analysed to determine the prevalence of MTP utilization, their compositions, challenges in application and areas of future need. RESULTS Eighteen respondents participated, representing 11 countries in the region. Thirteen hospitals implemented MTP, and eight included paediatrics. Eleven institutions used more than one definition of massive haemorrhage, with the most common being ≥10 red blood cell (RBC) units transfused for adults and replacement of >50% total blood volume in paediatrics. The majority of sites with MTPs utilized 1:1:1 RBCs:platelets:plasma ratio (70%). Variations were observed in the types and blood groups of components used. Two sites utilized whole blood, while six are considering it for future use. Utilization of adjunctive agents and frequency of laboratory testing varied among the sites. Challenges included the lack of medical expertise in protocol development, adherence and paediatric application. The need assessment emphasized the need for developing regional guidelines, standardized protocols and training initiatives. CONCLUSION Although several hospitals have adopted MTPs, variations exist in activation criteria, blood product ratios and monitoring. Challenges include the lack of medical expertise, protocol adherence and addressing paediatric needs. Standardizing protocols, enhancing training and paediatric application are crucial for improving massive transfusion management in the region.

Abstract
RATIONALE Amniotic fluid embolism (AFE) is a fatal obstetric condition that often rapidly leads to severe respiratory and circulatory failure. It is complicated by obstetric disseminated intravascular coagulation (DIC) with bleeding tendency; therefore, the introduction of venoarterial extracorporeal membrane oxygenation (VA-ECMO) is challenging. We report the case of a patient with AFE requiring massive blood transfusion, rescued using VA-ECMO without initial anticoagulation. PATIENTS CONCERNS A 39-year-old pregnant patient was admitted with a complaint of abdominal pain. An emergency cesarean section was performed because a sudden decrease in fetal heart rate was detected in addition to DIC with hyperfibrinolysis. Intra- and post-operatively, the patient had a bleeding tendency and required massive blood transfusions. After surgery, the patient developed lethal respiratory and circulatory failure, and VA-ECMO was introduced. DIAGNOSIS Based on the course of the illness and imaging findings, the patient was diagnosed with AFE. INTERVENTIONS By controlling the bleeding tendency with a massive transfusion and tranexamic acid administration, using an antithrombotic ECMO circuit, and delaying the initiation of anticoagulation and anti-DIC medication until the bleeding tendency settled, the patient was managed safely on ECMO without complications. OUTCOMES By day 5, both respiration and circulation were stable, and the patient was weaned off VA-ECMO. Mechanical ventilation was discontinued on day 6. Finally, she was discharged home without sequelae. LESSONS VA-ECMO may be effective to save the lives of patients who have AFE with lethal circulatory and respiratory failure. For safe management without bleeding complications, it is important to start VA-ECMO without initial anticoagulants and to administer anticoagulants and anti-DIC drugs after the bleeding tendency has resolved.

Heliyon 2024; 10:e30037. [PMID: 38765110 PMCID: PMC11101751 DOI: 10.1016/j.heliyon.2024.e30037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 04/11/2024] [Accepted: 04/18/2024] [Indexed: 05/21/2024] Open
Abstract
Background Hyperkalaemia is a common electrolyte abnormality seen in critically ill patients. In haemorrhagic shock, it may contribute to cardiac arrest and has been identified as a potential marker for tissue hypoxia. However, the significance of its role in haemorrhagic shock and its contribution to mortality remains unclear. This study aimed to examine the potential underlying pathophysiology and evaluate the incidence and characteristics of patients with hyperkalaemia on hospital arrival in bleeding trauma patients before transfusions and its mortality. Methods A retrospective cohort study was conducted on adult patients with traumatic bleeding admitted to a European Major Trauma Centre between January 2016 and December 2021. Patients were classified according to their serum potassium levels on arrival, and relevant clinical parameters between non-hyperkalaemic and hyperkalaemic patients were compared. Results Among the 83 patients in this study, 8 (9.6 %) presented with hyperkalaemia on arrival. The median shock index showed a higher tendency in the hyperkalaemic group. Hyperkalaemia was found to be more common among younger patients who sustained penetrating trauma. Mortality rates were higher in the hyperkalaemic group, but the difference was not statistically significant. Conclusion Our results suggest that hyperkalaemia occurs frequently in bleeding trauma patients on hospital arrival pre-transfusions, indicating a more severe illness. Our findings provide insights into the pathophysiology and characteristics of hyperkalaemia in bleeding trauma patients. Further studies are required to investigate the mechanisms by which hyperkalaemia contributes to mortality in haemorrhagic shock patients.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an overview of currently recommended treatment approaches for traumatic hemorrhage shock, with a special focus on massive transfusion. RECENT FINDINGS Severe trauma patients require massive transfusion, but consensual international definitions for traumatic hemorrhage shock and massive transfusion are missing. Current literature defines a massive transfusion as transfusion of a minimum of 3-4 packed red blood cells within 1 h. Using standard laboratory and/or viscoelastic tests, earliest diagnosis and treatment should focus on trauma-induced coagulopathy and substitution of substantiated deficiencies. SUMMARY To initiate therapy immediately massive transfusion protocols are helpful focusing on early hemorrhage control using hemostatic dressing and tourniquets, correction of metabolic derangements to decrease coagulopathy and substitution according to viscoelastic assays and blood gases analysis with tranexamic acid, fibrinogen concentrate, red blood cells, plasma and platelets are recommended. Alternatively, the use of whole blood is possible. If needed, further support using prothrombin complex, factor XIII or desmopressin is suggested.

Abstract
Despite advances in emergency transfer systems and trauma medicine, the incidence of preventable deaths due to massive hemorrhage remains high. Recent immunological research has elucidated key mechanisms underlying trauma-induced coagulopathy in the early stages of trauma, including sympathoadrenal stimulation, shedding of the glycocalyx, and endotheliopathy. Consequently, the condition progresses to fibrinogen depletion, hyperfibrinolysis, and platelet dysfunction. Coexisting factors such as uncorrected acidosis, hypothermia, excessive crystalloid administration, and a history of anticoagulant use exacerbate coagulopathy. This study introduces damage-control anesthetic management based on recent insights into damage-control resuscitation, emphasizing the importance of rapid transport, timely bleeding control, early administration of antifibrinolytics and fibrinogen concentrates, and maintenance of calcium levels and body temperature. Additionally, this study discusses brain-protective strategies for trauma patients with brain injuries and the utilization of cartridge-based viscoelastic assays for goal-directed coagulation management in trauma settings. This comprehensive approach may provide potential insights for anesthetic management in the fast-paced field of trauma medicine.

Abstract
Background Fibrinogen concentrate (FC) can be administered during massive transfusions to manage trauma-induced coagulopathy. However, its effectiveness in survival remains inconclusive due to scarce high-level evidence. This study aimed to investigate the hemostatic effects of FC regarding mortality in massive hemorrhage caused by trauma. Methods This retrospective study analyzed 839 patients who received massive transfusions (red blood cells (RBCs) ≥5 units in 4 hours or ≥10 units in 24 hours) at a level I trauma center between 2015 and 2022. Patients who were transferred to other hospitals or were deceased upon arrival, suffered or died from severe brain injury, and were aged 15 years or less were excluded (n=334). 1:2 propensity score matching was performed to compare the 'FC (+)' group who had received FC in 24 hours (n=68) with those who had not ('FC (-)', n=437). The primary outcome was mortality, and the secondary outcomes included transfusion volume. Results The variables for matching included vital signs, injury characteristics, prehospital time, implementation of resuscitative endovascular balloon occlusion of the aorta, and blood gas analysis results. The administration of FC did not significantly reduce or predict mortality (in-hospital, 24 hours, 48 hours, or 7 days). The FC (-) group received more units of RBC (25.69 units vs. 16.71 units, p<0.001, standardized mean difference [SMD] 0.595), fresh frozen plasma (16.79 units vs. 12.91 units, p=0.023, SMD 0.321), and platelets (8.76 units vs. 5.46 units, p=0.002, SMD 0.446) than the FC (+) group. Conclusion The use of FC did not show survival benefits but reduced transfusion requirements in traumatic massive hemorrhages, highlighting a need for future investigations. In the future, individualized goal-directed transfusion with FC may play a significant role in treating massive bleeding. Level of evidence IV, retrospective study having more than one negative criterion.

Abstract
(1) Background: The massive transfusion of packed red blood cells (RBCs) is a lifesaving procedure, but it is associated with complications, e.g., dysmagnesemia. Since magnesium is an intracellular ion, the transfused RBCs can significantly influence the magnesium concentration in the recipient's blood. (2) Methods: A retrospective study was performed among 49 patients hospitalized in the Central Clinical Hospital of the Medical University of Warsaw who received a massive blood transfusion (≥4 units/h). Data on laboratory results and patient history were collected from the hospital database. The intracellular RBCs magnesium concentration was measured in 231 samples using the colorimetric method. (3) Results: There were statistically significant changes in the mean serum magnesium concentration preoperatively and 24 h postoperatively (0.87 ± 0.13 vs. 1.03 ± 0.14, p < 0.00001) and 48 h postoperatively (0.87 ± 0.13 vs. 1.06 ± 0.15, p < 0.00001). Patients who died had significantly higher serum magnesium concentrations (p < 0.05). The median intracellular magnesium concentration in RBCs was 0.91 (0.55-1.8) mmol/L, which is below the reference values of 1.65-2.65 mmol/L. (4) Conclusions: Transfused RBCs significantly increased the serum magnesium concentration 24 h and 48 h postoperatively. It could be a result of mild hemolysis, as the median intracellular magnesium concentration in RBCs was below the reference values.
