Management of antiplatelet therapy for non-elective invasive procedures or bleeding complications: Proposals from the French Working Group on Perioperative Haemostasis (GIHP) and the French Study Group on Thrombosis and Haemostasis (GFHT), in collaboratio

The French Working Group on Perioperative Haemostasis (GIHP) and the French Study Group on Haemostasis and Thrombosis (GFHT), in collaboration with the French Society for Anaesthesia and Intensive Care (SFAR), drafted up-to-date proposals on the management of antiplatelet therapy for non-elective invasive procedures or bleeding complications. The proposals were discussed and validated by a vote; all proposals could be assigned with a high strength. Management of oral antiplatelet agents in emergency settings requires knowledge of their pharmacokinetic and pharmacodynamic parameters, evaluation of the degree of alteration of haemostatic competence and the associated bleeding risk. Platelet function testing may be considered. When antiplatelet agent-induced bleeding risk may worsen the prognosis, measures should be taken to neutralize antiplatelet therapy, by considering not only the efficacy of available means (which can be limited for prasugrel and even more for ticagrelor), but also the risks that these means expose the patient to. The measures include platelet transfusion at the appropriate dose and haemostatic agents (tranexamic acid; recombinant activated factor VII for ticagrelor). When possible, postponing non-elective invasive procedures at least for a few hours until the elimination of the active compound (which could compromise the effect of transfused platelets) or, if possible, for a few days (reduction of the effect of antiplatelet agents) should be considered.
