Severely injured trauma patients are often coagulopathic and early hemostatic resuscitation is essential. Previous studies have revealed linear relationships between thrombelastography (TEG...
There are situations where monitoring direct oral anticoagulants (DOACs) would be useful, including bleedings and trauma. The thromboelastographic technique has proven useful in bleeding situations in...
Tissue plasminogen activator (tPA) added to thrombelastography (TEG) detects hyperfibrinolysis by measuring clot lysis at 30 min (tPA-challenge-TEG). We hypothesize that tPA-challenge-TEG is a better ...
Trauma activation patients (TAP, 2014-2020) with 1) systolic blood pressure <90 mmHg (early) or 2) those who arrived normotensive but developed hypotension within 1H postinjury (delayed) were analyzed...
tPA-challenge-TEG was the best predictor of MT in the early hypotension subgroup (N = 212) with positive (PPV) and negative predictive values (NPV) of 75.0%, and 77.6%, respectively. tPA-challenge-TEG...
The tPA-challenge-TEG is the most accurate predictor of MT in trauma patients arriving hypotensive and offers early recognition of MT in patients with delayed hypotension....
Conventional rapid-thrombelastography (rTEG) cannot differentiate fibrinolysis shutdown from hypofibrinolysis, as both of these patient populations have low fibrinolytic activity. Tissue plasminogen a...
Adult trauma patients (n=981) with both rTEG and tPA-TEG performed <2 hours post-injury were included. rTEG LY30 was used to initially define fibrinolysis phenotypes (Hyperfibrinolysis >3%, Physiologi...
The median NISS was 22, 21% were female, 45% had penetrating injury, and overall mortality was 13%. The tPA-TEG LY30 inflection point for increased mortality was>35.5% (tPA sensitive, OR mortality 9.2...
The combination of rTEG and tPA-TEG increases the ability to predict mortality and suggests patient specific strategies for improved outcome....
Tuberculosis disease (TB) and tuberculosis infection (TBI) have been associated with increased risk of cardiovascular disease which may be connected to infection-related haemostatic changes. It is unk...
Individuals with TB or TBI were included from a TB outpatient clinic in Copenhagen, Denmark. Patients treated with antithrombotic medication or systemic immunosuppressants were excluded. TEG analysis ...
We included eleven individuals with TB with median [interquartile range] [IQR] age 52 (Liu et al. in Medicine (United States) 95, 2016) years and mean (standard deviation) (SD) body mass index (BMI) 2...
TEG analysis showed that treatments of TB and TBI were associated with reduced MA which may indicate the existence of cardiovascular benefits from therapy....
Registered at ClinicalTrials.gov 05 April 2021 with registration number NCT04830462....
[This retracts the article DOI: 10.1155/2022/4313394.]....
To analyze the changes in thrombelastography (TEG) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and the relationship with indicators related to lung function....
100 patients with AECOPD admitted to our hospital from May 2021 to May 2022 were selected as the AE group, and another 80 patients with a stable phase of COPD in the same period were selected as the S...
Patients in the AE group had lower...
There is a correlation between TEG-related indicators and lung function-related indicators in AECOPD patients, both of which can guide the diagnosis and treatment process of the disease and are worthy...
An increasing number of patients attending coronary artery bypass grafting (CABG) receive preoperative antiplatelet drugs (acetylsalicylic acid, clopidogrel, prasugrel, ticagrelor). The optimal assess...
This study was performed on patients presenting for first-time isolated CABG on therapy with an P2Y12 receptor blockers loading dose (clopidogrel [300 mg] or prasugrel [60 mg] or ticagrelor [180 mg]) ...
Forty-eight consecutive adult patients presenting for CABG were enrolled. Preoperative thromboelastography-platelet mapping showed platelet resistance to P2Y12 blockers receptor - 25% for clopidogrel ...
Preoperative thromboelastography-platelet mapping is helpful to detect harmful P2Y12 receptor blockers resistance and to minimize CABG waiting time avoiding unnecessary and life-threatening delays....
Intraoperative hemorrhage in cardiac surgery increases risk of morbidity and mortality. Low pre-operative and perioperative levels of fibrinogen, a key clotting factor, are associated with severity of...
This is a single center, prospective, cluster randomized trial with an adaptive design. Acquired hypofibrinogenemia will be assessed by rotational thromboelastometry (ROTEM) and the threshold for cryo...
This trial aims to provide evidence of the clinical efficacy of utilizing readily available thawed IFC during acute bleeding in the cardiac surgery setting compared to traditional cryo AHF....
ClinicalTrials.gov NCT05711524. Feb 3, 2023....
Timely and accurate assessment of coagulopathy is crucial for the management of primary postpartum hemorrhage (PPH). Thromboelastography (TEG) provides a comprehensive assessment of coagulation status...
We conducted a retrospective observational study in the ED of a university-affiliated tertiary hospital between November 2015 and August 2023. TEG was performed upon admission. The cutoff value for hy...
Among the 174 patients, 73 (42.0%) had hypofibrinogenemia. The need for massive transfusion was higher in the hypofibrinogenemia group (37.0% vs. 5.0%, p < 0.001). Among the TEG parameters, all values...
