Causes, management, and prognosis of severe gastrointestinal bleedings in critically ill patients with pancreatic cancer: A retrospective multicenter study

BackgroundGastrointestinal (GI) bleeding is a leading cause of intensive care unit (ICU) admission in pancreatic cancer patients. AimsTo analyze causes, ICU mortality and hemostatic treatment success rates of GI bleeding in pancreatic cancer patients requiring ICU admission. MethodsRetrospective multicenter cohort study between 2009 and 2021. Patients with a recent pancreatic resection surgery were excluded. ResultsNinety-five patients were included (62 % males, 67 years-old). Fifty-one percent presented hemorrhagic shock, 41 % required mechanical ventilation. Main GI bleeding causes were gastroduodenal tumor invasion (32 %), gastroesophageal varices (21 %) and arterial aneurysm (12 %). Arterial aneurysms were more frequent in patients with previous pancreatic resection (36 % vs 2 %, p < 0.001). Hemostatic procedures included gastroduodenal endoscopy in 81 % patients and arterial embolization in 28 % patients. ICU mortality was 19 %. Multivariate analysis identified four variables associated with mortality: performance status >2 (OR 9.34, p = 0.026), mechanical ventilation (OR 14.14, p = 0.003), treatment success (OR 0.09, p = 0.010), hemorrhagic shock (OR 11.24, p = 0.010). Treatment success was 46 % and was associated with aneurysmal bleeding (OR 29.89, p = 0.005), ongoing chemotherapy (OR 0.22, p = 0.016), and prothrombin time ratio (OR 1.05, p = 0.001). ConclusionIn pancreatic cancer patients with severe GI bleeding, early identification of aneurysmal bleeding (particularly in case of previous resection surgery) and coagulopathy management may increase the treatment success and reduce mortality.

Pro: Hemostasis Management of Patients on Extracorporeal Membrane Oxygenation Is Different Than Cardiopulmonary Bypass

Cardiopulmonary bypass and extracorporeal membrane oxygenation have many similarities, but there are significant differences in managing hemostasis. Cardiopulmonary bypass includes shorter mechanical circulatory support times, blood stasis, higher flows, and an increased blood-air interface. These factors cause differences in the risk of coagulopathy, management of anticoagulation, monitoring of the hemostatic system, and management of coagulopathy. This article aims to identify these key differences in the hemostatic system between patients on cardiopulmonary bypass and those on extracorporeal membrane oxygenation.

Multidisciplinary approach to obstetric disseminated intravascular coagulopathy management in low-income country: A survey.

To assess the uptake of a multidisciplinary team approach in obstetric disseminated intravascular coagulopathy (DIC) management in a low- to middle-income country. A cross-sectional observational study, in which a semi-structured and pre-tested questionnaire was used to collect data on the uptake by Nigerian obstetricians of the multidisciplinary team approach to obstetric DIC management. A total of 171 obstetricians responded, 82 (48.0%) were consultants and 89 (52.0%) were specialist registrars. Most (165; 96.5%) practiced in tertiary healthcare facilities and the multidisciplinary team approach was the most preferred (162; 94.7%) management approach. In all, 142 (83.0%) supported the invitation of hematologists always in the management whereas 115 (67.3%) participants recommended that involvement of specialists in the treatment should be when clinical presentation was suggestive of DIC. No significant association existed between years of obstetric practice and adoption of a multidisciplinary team-based approach (χ2 = 9.590; P = 0.252). A multidisciplinary approach is widely adopted in the management of obstetric DIC, with hematologists being a key member of the team.

Correction of Warfarin Coagulopathy for Non-bleeding Patients in the Outpatient Setting at an Ambulatory Care Organization: Application of Vitamin K Guidance

Background: Warfarin is an effective anticoagulant but requires close International Normalized Ratio (INR) monitoring and may occasionally require correction of excessive anticoagulation. Current guidelines provide limited practical guidance on the administration of vitamin K for the management of supratherapeutic INR levels ≥ 5.0 in non-bleeding outpatients. Objective: Based on expert consensus and guidelines, the Atrius Health Anticoagulation Management Services (AMS) has developed internal guidance for oral vitamin K use in highly selected populations. This study will describe the internal guidance for oral vitamin K use and present associated results and clinical outcomes Methods: Episodes with INR &gt; 5.0 were included, with vitamin K considered for episodes with INR ≥ 6. Moreover, compelling indications and exclusions to select ideal patients for vitamin K intervention were also defined Results: Overall, episodes were managed conservatively; of the 246 collected episodes of excessive anticoagulation, in 18 episodes (7%), patients received vitamin K, and in 228 (93%) episodes, patients did not receive vitamin K. The mean index INR was 6.0 (range 5.0 – 10.5, SD 1.07), with nearly 57% of episodes achieving INR correction and 15% of episodes developing INR overcorrection. High thrombotic risk patients, regardless of hemorrhagic risk, were less likely to receive vitamin K. Three episodes (1.2%) resulted in bleeding complications. No thrombotic complications occurred during the 30-day follow-up of the index INR value ≥ 5.0. Conclusion: Our internal guidance is a novel, standardized approach that serves as a decision support tool for the management of warfarin-associated coagulopathy and vitamin K intervention using patient-specific characteristics and index INR values. This guidance may assist other anticoagulation management services with practical applications and require validation in a prospective clinical trial.

An international, multicenter, survey-based analysis of practice and management of acute liver failure.

Acute liver failure (ALF) is an acute liver dysfunction with coagulopathy and HE in a patient with no known liver disease. As ALF is rare and large clinical trials are lacking, the level of evidence regarding its management is low-moderate, favoring heterogeneous clinical practice. In this international multicenter survey study, we aimed to investigate the current practice and management of patients with ALF. An online survey targeting physicians who care for patients with ALF was developed by the International Liver Transplantation Society ALF Special-Interest Group. The survey focused on the management and liver transplantation (LT) practices of ALF. Survey questions were summarized overall and by geographic region. A total of 267 physicians completed the survey, with a survey response rate of 21.36%. Centers from all continents were represented. More than 90% of physicians specialized in either transplant hepatology/surgery or anesthesiology/critical care. Two hundred fifty-two (94.4%) respondents' institutions offered LT. A total of 76.8% of respondents' centers had a dedicated liver-intensive or transplant-intensive care unit ( p < 0.001). The median time to LT was within 48 hours in 12.7% of respondents' centers, 72 hours in 35.6%, 1 week in 37.6%, and more than 1 week in 9.6% ( p < 0.001). Deceased donor liver graft (49.6%) was the most common type of graft offered. For consideration of LT, 84.8% of physicians used King's College Criteria, and 41.6% used Clichy Criteria. Significant differences were observed between Asia, Europe, and North America for offering LT, number of LTs performed, volume of patients with ALF, admission to a dedicated intensive care unit, median time to LT, type of liver graft, monitoring HE and intracranial pressure, management of coagulopathy, and utilization of different criteria for LT. In our study, we observed significant geographic differences in the practice and management of ALF. As ALF is rare, multicenter studies are valuable for identifying global practice.

Advanced airway management in the prehospital setting during traumatic out-of-hospital cardiac arrest following traffic collision in Japan, 2013-2019

Abstract Funding Acknowledgements Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Okinaka Memorial Institute for Medical Research; Toranomon Hospital. Background The European guideline on management of major bleeding and coagulopathy following trauma (sixth edition) recommend that endotracheal intubation or alternative airway management be performed without delay to facilitate adequate ventilation and oxygenation during trauma resuscitation. However, controversy remains as to whether advanced airway management should be provided for out-of-hospital cardiac arrest (OHCA) in the prehospital setting. Purpose This study aimed to examine the association of prehospital advanced airway management with outcomes after traumatic OHCA. Methods This observational study analyzed the Japanese government-led nationwide population-based registry data of OHCA patients. Patients with traumatic OHCA following traffic collision who received advanced life support in the prehospital setting from 2013 to 2019 were included. Propensity score matching was used to examine the association of advanced airway management with outcomes after traumatic OHCA following traffic collision. The primary outcome was one-month survival. Results A total of 5,617 patients (mean [SD] age, 60.1 [21.6] years; 68.6% male) were included. 3,822 (68.0%) received advanced airway management, and 1,795 (32.0%) did not. After adjusting for potential confounders using propensity score matching, advanced airway management was associated with decreased chance of one-month survival (23/1452 [1.6%] vs 43/1452 [3.0%]; RR, 0.53; 95%CI, 0.32-0.88; P=0.0128). Similar association was observed for prehospital return of spontaneous circulation (88/1452 [6.1%] vs 139/1452 [9.6%]; RR, 0.63; 95%CI, 0.49-0.82; P=0.0004). Conclusion Among patients with traumatic OHCA following traffic collision, advanced airway management was associated with decreased chance of one-month survival and prehospital return of spontaneous circulation.

Practice Algorithm of Rotational Thromboelastometry-Guided (ROTEM-Guided) Bleeding Management in Liver Transplantation.

Liver transplantation (LT) is frequently complicated by coagulopathy associated with end-stage liver disease, which is often multifactorial and associated with hemostatic disturbances affecting both the procoagulant and anticoagulant systems. This rebalanced coagulation system may lead to bleeding diathesis or increased clot formation. Conventional coagulation tests cannot reflect these complex changes because they can only illustrate deficiencies in the procoagulant system. Viscoelastic tests such as rotational thromboelastometry (ROTEM) have been used in LT and have shown useful for detecting coagulopathy and guiding transfusions. Implementation of ROTEM-guided bleeding management algorithms has proven effectiveness in reducing bleeding, transfusion needs, complication rates, and healthcare costs in LT. This document is intended to provide a practice algorithm for the management of major bleeding and coagulopathy during LT and to encourage adaptation of the guidelines to individual institutional circumstances and resources.

Blood Management in a Liver Transplant Recipient with Kidd (Jka) and Rhesus (D) Antibodies: A Case Report.

A 67-year-old man presented for urgent liver transplantation (LT). Screening revealed the rare combination of antiRhesus (D) and antiKidd Jk(a) antibodies, requiring antigen-negative red blood cells (RBC) for both phenotypes. This combination has not been reported during LT. Compatible RBCs were initially limited, requiring continued communication between the blood bank/blood supplier to obtain more, including frozen, units. Additional strategies included the use of cell salvage and intentional management of coagulopathy to limit bleeding and RBC requirement. This case highlights blood management during LT when D and Jk(a) antibodies may limit RBC supply and emphasizes the need for effective communication with the blood bank.

Prospective study of coagulation parameters in septicemic patients

Background and objectives. Sepsis is a critical clinical syndrome characterized by a systemic host response to infection, often leading to organ dysfunction and mortality. The association between early onset coagulopathy and mortality risk in septicemic patients remains an area of active investigation. This study aims to assess the association between early onset coagulopathy and increased mortality risk in septicemic patients. It also seeks to explore the role of procalcitonin (PCT) levels and demographic factors in the prognosis of septicemia. Material and methods. A cross-sectional study was conducted at Saveetha Medical College and Hospital, including 240 subjects who met the inclusion criteria. Patients were evaluated for the presence of coagulopathy (assessed by platelet count, INR, and aPTT values) and their PCT levels within 48 hours of admission. Data on demographic characteristics, underlying illnesses, and 28-day mortality were collected and analyzed. Results. The study population had a male preponderance (53.3%) with a mean age of 56.27 years. Diabetes mellitus was the most common underlying illness (32.5%). Coagulopathy was observed in 52.5% of patients, with thrombocytopenia and deranged INR and aPTT being significant indicators. Patients with life-threatening thrombocytopenia, severe PT-INR, and aPTT derangements showed high mortality rates (100%, 92.4%, and 90%-95.6% respectively). Mortality was significantly associated with coagulopathy and elevated PCT levels (&gt;10.0 ng/ml), with 41.7% of subjects dying within 28 days of admission. Conclusions. Early onset coagulopathy is significantly associated with increased mortality in septicemic patients, highlighting the importance of coagulation parameters and PCT levels in predicting outcomes indicating prompt recognition and management of coagulopathy in septicemia, especially in younger patients and those with elevated PCT levels.

Blood Transfusion for Major Trauma in Emergency Department.

Severe bleeding is the leading cause of death in patients with major trauma admitted to the emergency department. It is estimated that about 50% of deaths happen within a few minutes of the traumatic event due to massive hemorrhage; 30% of deaths are related to neurological dysfunction and typically happen within two days of trauma; and approximately 20% of patients died of multiorgan failure and sepsis within days to weeks of the traumatic event. Over the past ten years, there has been an increased understanding of the underlying mechanisms and pathophysiology associated with traumatic bleeding leading to improved management measures. Traumatic events cause significant tissue damage, with the potential for severe blood loss and the release of cytokines and hormones. They are responsible for systemic inflammation, activation of fibrinolysis pathways, and consumption of coagulation factors. As the final results of this (more complex in real life) cascade, patients can develop tissue hypoxia, acidosis, hypothermia, and severe coagulopathy, resulting in a rapid deterioration of general conditions with a high risk of mortality. Prompt and appropriate management of massive bleeding and coagulopathy in patients with trauma remains a significant challenge for emergency physicians in their daily clinical practice. Our review aims to explore literature studies providing evidence on the treatment of hemorrhage with blood support in patients with trauma admitted to the Emergency Department with a high risk of death. Advances in blood transfusion protocols, along with improvements in other resuscitation strategies, have become one of the most important issues to face and a key topic of recent clinical research in this field.

Update on the pathophysiology and management of acute trauma hemorrhage and trauma-induced coagulopathy based upon viscoelastic testing.

Uncontrolled hemorrhage and trauma-induced coagulopathy (TIC) are the two predominant causes of preventable death after trauma. Early control of bleeding sources and rapid detection, characterization and management of TIC have been associated with improved outcomes. However, recent surveys confirm vast heterogeneity in the clinical diagnosis and management of hemorrhage and TIC from acute trauma, even in advanced trauma centers. In addition, conventional coagulation assays, although still used frequently during the early assessment of bleeding trauma patients, have their limitations. This narrative review highlights the clinical value of rapid point-of-care viscoelastic testing for the early diagnosis and individualized goal-directed therapy in bleeding trauma patients with TIC.

The Relationship Between Transfusion in Cardiac Surgery Patients and Adverse Outcomes

ObjectivesTo understand if RBC transfusions are independently associated with a risk of mortality, prolonged intubation, or infectious, cardiac, or renal morbid outcomes. DesignRetrospective review. SettingSingle-institution, university hospital. Participants2458 Patients undergoing CABG and/or valvular surgery from July 2014 through January 2018. InterventionsNo interventions were done. Measurements and Main ResultsOur primary outcome was the occurrence of the adverse event, prolonged intubation. Infectious, cardiac, and renal composite outcomes were also defined. These composites, along with mortality, were individually analyzed and then combined to form the “any adverse events” composite. Preoperative demographic and intraoperative parameters were analyzed as univariate risk factors for adverse outcomes. Logistic regression was used to screen variables with a p-value criterion of p < 0.05 for entry into the model selection procedure. Backward selection algorithm was used with variable entry and retention criteria of p < 0.05 to select the final multivariable model. Multivariable logistic regression models were used to determine whether there was an association between volume of RBC transfusion and the defined adverse event after adjusting for covariates. A p-value<0.01 was considered statistically significant in the final model of each aim to adjust for multiple comparison. The final logistic models for each of the following outcomes indicates increased risk of that outcome per each additional unit of RBC transfused. For prolonged intubation the OR=1.493, p<0.0001, for the infectious composite outcome, the OR= 1.358, p<0.0001, for adverse renal outcomes, the OR=1.247, p<0.0001, and for any adverse event, the OR=1.467, p<0.0001. ConclusionsWe demonstrate a strong independent association between RBC transfusion volume and adverse outcomes after cardiac surgery. Efforts should be undertaken such as preoperative anemia management and control of coagulopathy in order to minimize the need for RBC transfusion.

INVESTIGATION OF A POINT-OF-CARE VISCOELASTIC COAGULATION MONITOR AND ITS COMPARISON TO THROMBOELASTOGRAPHY IN CLINICALLY HEALTHY AFRICAN ELEPHANTS (LOXODONTA AFRICANA).

Elephant endotheliotropic herpesvirus (EEHV) can induce fatal hemorrhagic disease (HD) in African elephants (Loxodonta africana). Once clinical signs develop, progression is rapid, even with aggressive treatment. There is a critical need to develop point-of-care diagnostic tests to aid in identification of EEHV-HD prior to the onset of overt clinical signs. Study objectives were to investigate a novel, point-of-care viscoelastic coagulation monitor (VCM Vet), compare the results to thromboelastography (TEG), and report traditional hemostatic analytes in adult African elephants. Whole blood was collected from seven clinically healthy elephants (four females and three males, 18-47 yr) and analyzed in duplicate via VCM Vet and kaolin-activated TEG 1-3 and 30 min following collection, respectively. Separated plasma was frozen for ancillary coagulation testing. Both analyses generated quantifiable clotting reactions with variables (median [range]) describing clot formation rate (VCM Vet, clot time = 682 s [530-987 s], clot formation time = 244 s [186-744 s], Alpha = 40° [14-47°]; TEG, reaction time = 6.2 min [3.7-11.8 min], kinetic time = 1.3 min [0.9-2.6 min], Alpha = 70° [57-77°]), clot strength (VCM Vet, maximum clot formation = 34 units [20-45 units]; TEG, maximum amplitude = 75 mm [69-80 mm], shear elastic modulus strength = 14.7 Kdynes/s [11.3-19.5 Kdynes/s]), and clot lysis (VCM Vet, lysis index at 30 min = 100% [100-99%], lysis index at 45 min = 98% [95-100%]; TEG, lysis index at 30 min = 0% [0-0.4%], lysis index at 60 min = 1.4% [0-2.6%]) recorded. Additional testing (median [range]) included D-dimer concentration (33 ng/ml [28-94 ng/ml]), prothrombin time (12.4 s [12.2-13.2 s]), activated partial thromboplastin time (17.2 s [14.2-18.8 s]), and fibrinogen concentration (297 [282-383] mg/dL). Tracings generated by VCM Vet and TEG were clinically similar, and there was visual agreement and minimal difference between quantitative variables for duplicate tests. VCM Vet is a promising, user-friendly tool for use in identification and management of coagulopathies in African elephants.

Basic Principles of Rotational Thromboelastometry (ROTEM®) and the Role of ROTEM-Guided Fibrinogen Replacement Therapy in the Management of Coagulopathies.

Rotational thromboelastometry (ROTEM) is a viscoelastic method, which provides a graphical and numerical representation of induced hemostasis in whole blood samples. Its ability to quickly assess the state of hemostasis is used in the management of bleeding from a variety of causes. The separate activation of particular parts of hemocoagulation in INTEM, EXTEM, and FIBTEM tests allows for a more comprehensive and faster evaluation of the missing component of hemostasis followed by targeted therapy. One of the most common cause of coagulopathy is trauma-induced coagulopathy. Fibrinogen replacement therapy by ROTEM allows for the use of a standard dosage of fibrinogen, which has been shown to be successful in preventing dilutional coagulopathy following colloid and crystalloid replacement and excessive amount of allogeneic blood transfusions. The best reflection of fibrinogen activity is observed in the FIBTEM assay, where fibrinogen replacement therapy is recommended at an MCF (maximum clot firmness) of FIBTEM < 10 mm and FIBTEM A10 < 7 mm. ROTEM also plays an important role in the diagnostic and management of inherited fibrinogen disorders. These can be manifested by bleeding complications, where changes in the MCF parameter are the most useful tool for assessing the effectiveness of fibrinogen replacement therapy. ROTEM-guided bleeding management algorithms effectively reduce the number of transfusions, healthcare costs, and complications, leading to the improvement of patient safety and overall health.
