Thrombin generation testing has been used to provide information on the coagulation phenotype of patients. The most used technique is the calibrated automated thrombogram (CAT) but it suffers from a lack of standardization, preventing its implementation in routine. The ST Genesia is a new analyzer designed to assess thrombin generation based on the same principle as the CAT. Unlike the CAT system, the ST Genesia is a benchtop, fully automated analyzer, able to perform the analyses individually and not by batch, with strict control of variables such as temperature and volumes, ensuring, theoretically, maximal reproducibility.

ABSTRACTIntroduction: Idarucizumab is a specific antagonist for dabigatran etexilate (DE). The recent market authorization of idarucizumab in Europe and the USA may reassure prescribers of DE, as it can increase the safety of the emergency management of patients taking this anticoagulant. However, idarucizumab use should be limited to specific indications to avoid unnecessary risks to patients and costs to healthcare systems.Areas covered: The authors provide an overview of idarucizumab development and its pharmacokinetic and pharmacodynamic properties. The results of the clinical phase III trial RE-VERSE AD and a review of recent case reports of idarucizumab use in emergency contexts are also discussed.Expert opinion: Although idarucizumab has shown clear efficacy in reversing dabigatran-induced coagulopathy, its overall effects on patient outcome have not been proven. Information regarding the clinical context in which patients on DE are admitted for emergency treatment, and accurate laboratory tests of dabigatran plasma level during reversal may inform selection and help with the follow-up of patients who may benefit from idarucizumab. Idarucizumab should be integrated into protocol for the emergency management of patients on DE. Furthermore, the benefit of idarucizumab in specific indications such as acute ischemic stroke should be investigated.

Purpose. Airway stenting offers good palliation and improves the quality of life in patients with inoperable bronchotracheal stenosis. However, in some cases, the management of stenting can be life-threatening. Hence, a strategy for maintaining oxygenation and hemodynamic stability should be anticipated to avoid critical situations. Herein, we report the use of extracorporeal membrane oxygenation (ECMO) in bronchotracheal stenting management to secure oxygenation and facilitate interventions. Methods. We retrospectively reviewed all patients who underwent rigid bronchoscopy under ECMO support for the management of bronchotracheal stenting at CHU UCL Namur hospital (Belgium), between January 2009 and December 2019. Results. We included 14 bronchoscopy cases performed on 11 patients (3 patients underwent 2 bronchoscopies) in this study; 12 were performed on males and 2 on females. The median age was 54 years. There were 11 benign and 3 malignant etiologies for the central airway obstruction/stenosis. Eight cases were supported by venovenous ECMO and six by venoarterial ECMO. The median ECMO time was 267 minutes. The weaning of ECMO support was successful in all cases. In most cases, the procedures were performed effectively and safely. Only two local complications caused by the cannulation of ECMO were reported, and anticoagulation was adapted to avoid bleeding at the operating site and clot formation in the system. Conclusion. Elective ECMO support was helpful and safe for the high-risk management of bronchotracheal stenting with rigid bronchoscopy and was not associated with any additional significant complications.
