Quantification of bleeding during dental extraction in patients on dual antiplatelet therapy

ABSTRACT

In spite of the possibility of triggering thromboembolic events, many professionals indicate the suspension of antiplatelet agents before dental surgical procedures. The aim of this study was to perform a quantitative assessment of intraoperative bleeding in patients on dual antiplatelet therapy. A case-control study was conducted in patients on dual antiplatelet therapy (APT group) and in patients who did not use these medications (control group). The following examinations were requested complete blood cell count, blood coagulation tests, and platelet aggregation. The quantity of bleeding was measured intraoperatively by collection of aspirated blood. The mean volume of blood lost during the surgical procedure was 6.10ml in the control group and 16.07ml in the APT group (P=0.002). The mean volume of blood lost per minute was 0.60ml/min in the control group and 1ml/min in the APT group (P=0.001)...
