Abstract

NAZAR J., Claudio; CONTRERAS C., José Ignacio; MOLINA P., Ian  and  FUENTES H., Ricardo. Perioperative management of patients using antiplatelet agents. Rev Chil Cir [online]. 2018, vol.70, n.3, pp.291-299. ISSN 0718-4026.  http://dx.doi.org/10.4067/s0718-40262018000300291.

The use of antiplatelet drugs for primary and secondary prevention of cardiovascular disease events is a common clinical practice. Antiplatelet therapy significantly decreases the incidence of cardiovascular disease events, including acute myocardial infarction and cerebrovascular accident. It is increasingly common to face patients on antiplatelet therapy who will undergo some surgical procedure, so it is essential to know the perioperative management of these drugs, to reduce the risks and complications associated with the suspension or maintenance of these therapies in the perioperative period. The most common antiplatelet agents used in Chile are acetylsalicylic acid and thienopyridines, of which clopidogrel is the most frequent one. The perioperative management of these drugs has to be based on the individual thrombotic risk of each patient and the risk of hemorrhage of each surgery. In noncardiac surgeries, it is suggested to maintain acetylsalicylic acid, except in patients with low to moderate thrombotic risk who will undergo surgeries with a high risk of bleeding, in which case it is recommended to suspend it 5 to 7 days before surgery. Clopidogrel is suggested to be discontinued 5 days before surgery, except in patients with high thrombotic risk who will undergo surgical procedures with low to moderate risk of hemorrhage. In myocardial revascularization surgeries, it is recommended to maintain acetylsalicylic acid and to suspend clopidogrel 5 days before the procedure. Once assuring adequate surgical hemostasis, it is suggested to reinitiate acetylsalicylic acid 6 hours after surgery and to reinitiate clopidogrel during the first 24 postoperative hours.
