Clin Appl Thromb Hemost 2023; 29:10760296231209927. [PMID: 37933155 PMCID: PMC10631354 DOI: 10.1177/10760296231209927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 09/19/2023] [Accepted: 10/09/2023] [Indexed: 11/08/2023] Open
Abstract
Hemostatic disturbances after cardiac surgery can lead to excessive postoperative bleeding. Thromboelastography (TEG) was employed to evaluate perioperative coagulative alterations in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB), investigating the correlation between factors concomitant with cardiac surgery and modifications in coagulation. Coagulation index as determined by TEG correlated significantly with postoperative bleeding at 24-72 h after cardiac surgery (P < .001). Among patients with a normal preoperative coagulation index, those with postoperative hypocoagulability showed significantly lower nadir temperature (P = .003), larger infused fluid volume (P = .003), and longer CPB duration (P = .033) than those with normal coagulation index. Multivariate logistic regression showed that nadir intraoperative temperature was an independent predictor of postoperative hypocoagulability (adjusted OR: 0.772, 95% CI: 0.624-0.954, P = .017). Multivariate linear regression demonstrated linear associations of nadir intraoperative temperature (P = .017) and infused fluid volume (P = .005) with change in coagulation index as a result of cardiac surgery. Patients are susceptible to hypocoagulability after cardiac surgery, which can lead to increased postoperative bleeding. Ensuring appropriate temperature and fluid volume during cardiac surgery involving CPB may reduce risk of postoperative hypocoagulability and bleeding.

Abstract
We have reviewed a large number of relevant literature to determine the deficiencies of orthopedics in the diagnosis and prevention of venous thromboembolism(VTE)events during the perioperative period, and found that the TEG technology has been widely used after liver transplantation, which may make up for the deficiencies. This review expounds the detection principle and latest thromboelastography (TEG) development, and highlights the advantages of TEG over previous screening methods in diagnosing hypercoagulability. By analyzing the correlation and consistency between TEG and conventional coagulation test, reliable indexes for diagnosing hypercoagulability and important parameters for guiding perioperative anticoagulation treatment were summarized. Furthermore, our work contributes to further studies of TEG in orthopedics. Based on the research results, we believe that TEG may help orthopedists to identify and predict VTE events, use anticoagulants, eventually reduce the occurrence of VTE events.

Abstract
Aortic pathology is always a challenge for the clinician, and must be diagnosed and treated by a multidisciplinary team due to the technical and technological complexity of the resources used. Ongoing efforts to implement a systematic, protocolized approach involving "Aortic teams" made up of cardiologists, cardiac surgeons, vascular surgeons, anaesthesiologists and radiologists, among others are now leading to improved outcomes. The aim of this consensus document drawn up by the Aortic working groups of the Spanish Society of Anaesthesiology, Resuscitation and Pain Therapy (SEDAR) and the Spanish Society of Thoracic and Cardiovascular Surgery (SECTCV) is to disseminate a set of working protocols. The latest consensus document of the European Association for Cardio-Thoracic Surgery (EACTS) and the European Society for Vascular Surgery (ESVS) define the concept of "AORTIC TEAM"(1). The aortic team should be closely involved from diagnosis to treatment and finally follow-up, and should be formed of cardiac and vascular surgeons working together with anaesthesiologists, cardiologists, radiologists and geneticists. Treatment of aortic pathologies should be centralised in large centres, because this is the only way to effectively understand the natural course of the disease, provide the entire range of treatment options under one umbrella and treat potential complications. A streamlined emergent care pathway (24/7 availability), adequate transportation and transfer capabilities, as well as rapid activation of the multidisciplinary team must be available. In light of the complexity and constant evolution of therapeutic options, we present this first version of the Anaesthesiology and surgical guidelines for surgery of the ascending aorta and aortic arch. Some questions will no doubt remain unanswered, and future versions will include new techniques that, though implemented in some centres, are still not widely recommended.

Abstract
The optimal thromboprophylactic strategy for patients affected by Coronavirus disease 2019 (COVID-19) has been debated among experts. This study evaluated the safety and efficacy of a thromboprophylaxis algorithm. This was a retrospective, single-center study in critically ill patients admitted to the intensive care unit (University affiliated Hospital) for acute respiratory failure due to Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2). From March 16 to April 9, 2020, thromboprophylaxis was adjusted according to weight (control group, n = 19) and after this date, thromboprophylaxis depended on an algorithm based on thrombotic and hemorrhagic risk factors (protocol group, n = 13). With regard to safety (number of major bleeding events and blood transfusions), the groups were not significantly different. With regard to efficacy, the number of thrombotic events decreased from 37 to 0%, p = 0.025 after implementation of the algorithm. Also, peak fibrinogen dropped from 8.6 (7.2-9.3) to 6.5 (4.6-8.4) g/L, p = 0.041 and D-dimers from 2194 (1464-3763) to 1486 (900-2582) ng/mL, p = 0.0001. In addition, length of stay declined from 19 (10-31) to 5 (3-19) days, p = 0.009. In conclusion, a tailored thromboprophylaxis algorithm (risk stratification based on clinical parameters and biological markers) reduce thrombotic phenomena in critically ill COVID-19 patients without increasing major bleeding.

Abstract
OBJECTIVES Tranexamic acid is used to prevent hyperfibrinolysis and reduce postoperative bleeding and blood transfusions in on-pump cardiac surgery. We evaluate the efficacy of low or high dose tranexamic acid in a prospective cohort study conducted in Valencia. MATERIALS AND METHODS A total of 427 patients were recruited between January 2019 and January 2020, 207 in the Hospital General Universitario (low dose [LD]) and 220 in the Hospital Universitario y Politécnico La Fe (high dose [HD] and intermediate dose [ID]). We recorded the presence of hyperfibrinolysis on rotational thromboelastometry, intra- and postoperative administration of blood products, chest tube output within the first 12 h, and incidence of convulsions. Univariate and multivariate comparisons were performed. Univariate analysis of all categories was performed after propensity score matching between LD and HD and between LD and ID. RESULTS There were no statistically significant differences in: appearance of hyperfibrinolysis, administration of blood products, postoperative chest tube output within the first 12 h, or occurrence of convulsions. Group LD received less fibrinogen than group HD (P = .014) and ID (P = .040) but more fresh frozen plasma than group ID (P = .0002). CONCLUSIONS Administration of low-dose tranexamic acid is as effective as higher doses in hyperfibrinolysis prophylaxis and the prevention of postoperative bleeding in cardiac surgery.

Abstract
Algorithms for treatment of diffuse bleeding in cardiac surgery are based on intervention thresholds of coagulation tests, such as rotational thromboelastometry (ROTEM) or conventional laboratory tests. The relationship between these two approaches is unclear in patients with increased risk of coagulation abnormalities. We retrospectively analyzed the data of 248 patients undergoing major cardiac and/or aortic surgery. ROTEM and conventional laboratory tests were performed simultaneously after termination of cardiopulmonary bypass and protamine administration to investigate the extrinsic and intrinsic system, and to determine deficiencies in platelets and fibrinogen. We evaluated the association between ROTEM and conventional tests by linear regression analysis and compared the frequency of exceeding established thresholds for clinical intervention. Significant linear associations between ROTEM 10 min after the start of coagulation, and plasma fibrinogen concentration or platelet count (FIBTEM A10, R2 = 0.67, p < 0.001; EXTEM A10, R2 = 0.47, p < 0.001) were obtained. However, the 95% prediction intervals exceeded clinically useful ranges (92–233 mg/dL fibrinogen at the intervention threshold of FIBTEM A10 = 10 mm; 14 × 103–122 × 103/µL platelets at the intervention threshold of EXTEM A10 = 40 mm). The association between EXTEM and INR (R2 = 0.23), and INTEM and aPTT (R2 = 0.095) was poor. The frequency of exceeding intervention thresholds and, consequently, of triggering treatment, varied markedly between ROTEM and conventional tests (p < 0.001 for all comparisons). The predictability of conventional coagulation test results by ROTEM is limited, thus hampering the interchangeability of methods in clinical practice.

Abstract
Optimal anticoagulation monitoring in patients with extracorporeal membrane oxygenation (ECMO) is fundamental to avoid hemorrhagic and thromboembolic complications. Besides conventional coagulation tests, there is growing interest in the use of viscoelastic hemostatic assays (VHA), in particular of tromboelastography (TEG). Evidence on the use of rotational thromboelastometry (ROTEM) is lacking in this setting. The aim of the study was to evaluate ROTEM as a tool for assessing hemostasis during ECMO, by comparing it to TEG and conventional coagulation assays. We conducted a prospective, observational, single-center study on adult patients on ECMO support anticoagulated with unfractioned heparin (UFH). Kaolin reaction time (R, min) for TEG and INTEM clotting time (CT, sec) for ROTEM were analyzed and compared with conventional coagulation tests. In the study period, we included 25 patients on ECMO support (14 V-A and 11 V-V); 84 data points were available for the analysis. Median UFH infusion rate was 15 [11-18] IU/min/kg. Median values for activated partial thromboplastin time (aPTT) ratio, Kaolin TEG R time, and INTEM CT were 1.44 [1.21-1.7], 22 [13-40] min, and 201 [183-225] sec, respectively. INTEM CT (ROTEM) showed a moderate correlation with standard coagulation tests (R2 = 0.34 and 0.3 for aPTT and activated clotting time (ACT), respectively, p < 0.001). No significant correlation was found between INTEM CT and Kaolin R time (R2 = 0.01). Further studies are needed to identify an appropriate anticoagulation target for ROTEM during ECMO.

Abstract
BACKGROUND Changes in coagulability during the hyperacute phase within 24 h after transcatheter aortic valve implantation (TAVI) for Heyde's syndrome, or aortic stenosis complicated by gastrointestinal angiodysplasia and acquired coagulation dysfunction, have not been clarified. We evaluated perioperative changes in coagulability using rotational thromboelastometry (ROTEM). CASE PRESENTATION A female patient with Heyde's syndrome in her 80s underwent TAVI. ROTEM showed coagulation dysfunction before and at 6 h after surgery. Improvements in coagulation function started at 12 h after surgery. Based on ROTEM findings, oral administration of antiplatelet agents was started on the day after surgery. No hemorrhagic complications were observed in the postoperative phase. CONCLUSIONS Evaluation of coagulation function using ROTEM was useful for monitoring perioperative hemostasis and coagulation in this patient.

Abstract
OBJECTIVES A hemostasis management system (HMS) is a point-of-care method for heparin and protamine titration. The authors hypothesized that protamine dosing over the HMS estimate would be associated with elevated activated clotting time (ACT), increased bleeding, and transfusion owing to protamine's anticoagulant activity. DESIGN A retrospective cohort study. SETTING Single-center university hospital. PARTICIPANTS One hundred eighty-nine patients undergoing elective coronary artery bypass grafting surgery. INTERVENTIONS Patients were stratified into 3 groups per ratio of actual total administered protamine versus the HMS-derived protamine estimate: (1) low-ratio (≤66% of HMS estimate), (2) moderate-ratio (66%-100% of HMS estimate), and (3) high-ratio (>100% of HMS estimate). MEASUREMENTS AND MAIN RESULTS The primary endpoints were post-protamine ACT, and residual heparin levels on HMS among the 3 groups in addition to bleeding and transfusion. There were 54 (28.6%) patients in the low, 95 (50.3%) in the moderate, and 40 (21.2%) in the high-ratio group. The high-ratio patients who were overdosed with protamine relative to the HMS estimate had elevated ACT, international normalized ratio, and activated partial thromboplastin time values, and subsequently received more red blood cell (RBC) and non-RBC transfusions compared to lower-ratio groups. Higher actual/HMS protamine ratios were associated independently with post-protamine ACT elevations after adjustment for sex, body mass index (BMI), and cardiopulmonary bypass (CPB) time. CONCLUSION Most patients received the protamine dose sufficiently close to the HMS estimate, but protamine dosing above the HMS estimate occurred in both obese and nonobese patients, which was associated independently with prolonged ACT after adjusting for sex, BMI, and CPB time.

Abstract
BACKGROUND Although the coagulation system is evolutionary well preserved, profound species differences exist in viscoelastic as well as in common laboratory tests of coagulation. OBJECTIVE Evaluating differences in clot formation and material characterisation of clots of four mammalian species on macro-, micro- and nanoscales by the means of rheometry, scanning electron microscopy (SEM) and small angle x-ray scattering (SAXS). METHODS Blood samples were collected from healthy human volunteers, laboratory rats (HL/LE inbred strain), warmblood horses and dromedary camels. Clot formation was observed by oscillating shear rheometry until plateau formation of the shear storage modulus G', at which point selected clots were prepared for scanning electron microscopy. SEM images were analysed for fibre diameter and fractal dimension. Additionally, scattering profiles for plasma and whole blood samples were obtained with SAXS. RESULTS Viscoelasticity of clots showed great interspecies variation: clots of rats and horses exhibited shorter clotting times and higher G' plateau values, when compared to human clots. Camel clots showed unique clotting characteristics with no G' plateau formation in the timeframe observed. Less differentiating features were found with SEM and SAXS, although the rat fibre network appears to be more convoluted and dense, which resulted in a higher fractal dimension. CONCLUSION Clotting kinetic differs between the species, which is not only of clinical interest, but could also be an important finding for animal models of blood coagulation.

Abstract
OBJECTIVE Thromboelastometry is a viscoelastometric method for haemostasis testing in a whole blood sample. The aim of this study was to assess the results of using thromboelastometry as guidance for blood management in cardiac surgery, postoperative adverse events and ICU stay. MATERIAL AND METHOD Analytical and comparative non-randomised quasi-experimental prospective study with a retrospective control group. The inclusion criteria for the 80 patients were: patients undergoing cardiac surgery who had had prior cardiac surgery, endocarditis surgery or aortic arch surgery. Thirty-one patients were treated following routine transfusion practice during surgery (group A). The other 49 patients were treated with thromboelastometrically guided transfusion algorithms (group B). The main objective was blood products transfused, and postoperative adverse events and ICU stay were the secondary objectives. RESULTS Statistical analysis showed lower transfusion rates of fresh-frozen plasma in group B compared to group A (P<.001), as well as red blood cell transfusion during surgery with an average transfusion rate of 3.9 units in group A in comparison to 2.67 units in group B (P=.125). Moreover, fibrinogen infusion was increased in group B compared to group A (P=.019). In addition, a lower rate of respiratory adverse events was found in group B (P=.019). There was a significant decrease in ICU stays over 7 days in group B compared to group A (P=.031). CONCLUSIONS Using thromboelastometry guidance for blood management led to a meaningful reduction of fresh frozen plasma transfusion during surgery. This probably resulted in a reduction in respiratory adverse events after surgery and length of ICU stay in our patients.

Abstract
Organ transplantation recipients present unusual challenges with regard to blood transfusion. Although this patient population requires a larger proportion of blood product resources, liberal transfusion of allogeneic blood products can lead to a plethora of complications. Recent trends suggest that efforts to minimize bleeding, conserve products, and target transfusion to specific deficits and needs are increasingly becoming the standard practice; these must all occur with optimization of graft function and preservation in mind. With newer monitoring modalities and factor concentrates, the approach toward transfusion and bleeding in organ transplantation has rapidly improved in recent years.

Abstract
Hemorrhage is a major contributor to morbidity and mortality during the perioperative period. Current methods of diagnosing coagulopathy have various limitations including long laboratory runtimes, lack of information on specific abnormalities of the coagulation cascade, lack of in vivo applicability, and lack of ability to guide the transfusion of blood products. Viscoelastic testing offers a promising solution to many of these problems. The two most-studied systems, thromboelastography (TEG) and rotational thromboelastometry (ROTEM), offer similar graphical and numerical representations of the initiation, formation, and lysis of clot. In systematic reviews on the clinical efficacy of viscoelastic tests, the majority of trials analyzed were in cardiac surgery patients. Reviews of the literature suggest that transfusions of packed red blood cells (pRBC), plasma, and platelets are all decreased in patients whose transfusions were guided by viscoelastic tests rather than by clinical judgement or conventional laboratory tests. Mortality appears to be lower in the viscoelastic testing groups, despite no difference in surgical re-intervention rates and massive transfusion rates. Cost-effectiveness studies also seem to favor viscoelastic testing. Viscoelastic testing has also been investigated in small studies in other clinical contexts, such as sepsis, obstetric hemorrhage, inherited bleeding disorders, perioperative thromboembolism risk assessment, and management of anticoagulation for patients on mechanical circulatory support systems or direct oral anticoagulants (DOACs). While the results are intriguing, no systematic, larger trials have taken place to date. Viscoelastic testing remains a relatively novel method to assess coagulation status, and evidence for its use appears favorable in reducing blood product transfusions, especially in cardiac surgery patients.

Abstract
Evidence exists on the morbiduty and mortality associated with both massive blood loss and transfusion in cardiac surgical patients. Monitoring of the vesicoelastic properties of blood using rotational thromboelastometry and thromboelsatography (TEG) has been a major step towards ameliorating the risks associated with these 2 evils by providing trageted goal-directed blood product resuscitation. Point of care ROTEM and TEG overcome many of the current limitatons of conventional laboratory coagulation testing. Despite the peaking interest and widespread use there is a lack of consensus whetehr the use of these devices to guide blood product resucistation is associated with a reduction in mortality. Also, both ROTEM and TEG suffer from some limitations resulting in a lack of agreement on the duperiority of one device versus the other. In this concise review we discuss the operational charecteristics of both devices and the pro-side of the use of ROTEM in cardiac surgery backed with the most recent evidence.

Abstract
BACKGROUND Elderly patients often suffer from cardiovascular diseases and are treated with anticoagulation medications, which must be taken into consideration when planning elective surgery. OBJECTIVE The etiology, diagnostic work-up and clinical management of selected inherited and acquired hemophilic and thrombophilic coagulation disorders are described. METHODS Data from clinical studies, current guidelines and expert opinions are discussed. RESULTS Beside inherited hemophilic coagulation defects, elderly patients very frequently show an acquired bleeding tendency caused by the intake of analgesic drugs or long-term medication due to cardiovascular diseases. In rare cases, elderly patients can develop acquired hemophilia caused by autoantibodies to coagulation factors resulting in a severe bleeding disorder. Moreover, elderly patients have an increased risk to develop venous or arterial thrombotic events. Prior to surgery a relevant bleeding tendency should be excluded by the combination of medical history, clinical investigation and screening of laboratory parameters. If laboratory parameters are outside the normal range, e.g. a prolonged activated partial thromboplastin time (aPTT), the reasons must be clarified prior to an elective surgery. CONCLUSION The clinical management of elderly patients under anticoagulation treatment should start early and must also cover the post-surgery period. When planning treatment for patients at risk, a physician qualified in clinical hemostaseology should be consulted. For the management of thrombosis prophylaxis, the implementation of clinical guidelines is a valuable measure.
