¿Es efectivo el ácido tranexámico en la hemorragia digestiva alta aguda?

Upper gastrointestinal bleeding constitutes a medical-surgical emergency given its important associated morbidity and mortality. The antifibrinolytic tranexamic acid might help stopping bleeding, but controversy remains about its role in this setting. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified five systematic reviews including eight randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded tranexamic acid probably decreases rebleeding and mortality, without increasing thromboembolic adverse effects in patients with upper gastrointestinal bleeding.
