“…POC tests (kaolin TEG, RapidTEG, and INTEM time to clot formation) detected dabigatran-induced coagulopathy in case reports of actively bleeding patients. [27][28][29] Concordantly, kaolin TEG and RapidTEG were prolonged in patients under a dabigatran 150 mg twice daily regimen studied by Davis et al 30 Similarly, Herrmann et al took blood samples from 17 patients 2 hours after the oral dose (150 mg twice daily) and performed multiple viscoelastic tests: both R parameter at kaolin TEG and CT at EXTEM and INTEM were found significantly prolonged, with the lower 95% confidence interval value being higher than the upper normal range for each test. 31 Furthermore, the mean plasmatic concentration of dabigatran in this set of patients was 129 ng/mL, in agreement with the finding of similar concentrations in in vitro studies.…”

“…Several case reports describe the treatment of hemorrhages in patients under dabigatran therapy and their impact on viscoelastic tests. Aron et al 28 reported the case of a 76-year-old man who developed intracranial hemorrhage while taking dabigatran 150 mg twice daily. At the first sampling, the R parameter at TEG was 12.8 minutes and was reduced to 8.0 minutes after administration of rFVIIa (90 μg/kg).…”

“…In contrast, in one case of severe bleeding due to a transseptal perforation at an atrial fibrillation ablation procedure bleeding was stopped by infusion of 26 U/kg APCC [25]. In a fatal case with dabigatran-associated intracranial hemorrhage, rFVIIa at 90 µg/kg body weight shortened the prolonged activated partial thromboplastin time and the prothrombin time, improved thrombin generation and shortened the R-time [26]. Case reports thus show conflicting results [23][24][25][26][27].…”

Case reports thus show conflicting results [23][24][25][26][27]. Furthermore, a very important limitation regarding case studies is that only a small fraction of cases are reported in the literature or available through other open sources.…”

“…), jie normalizavosi tik pasibaigus dabigatrano veikimui. Straipsnio autorių teigimu, šis klinikinis atvejis parodo, kad TEG yra labai svarbus tyrimas monitoruojant dabigatrano hipokoaguliacinį poveikį ūmiose situacijose [40].…”
