Since 2011, data on patients exposed to direct oral anticoagulants (DOAs) while undergoing invasive procedures have accumulated. At the same time, an increased hemorrhagic risk during perioperative bridging anticoagulation without thrombotic risk reduction has been demonstrated. This has led the GIHP to update their guidelines published in 2011. For scheduled procedures at low bleeding risk, it is suggested that patients interrupt DOAs the night before irrespective of type of drug and to resume therapy six hours or more after the end of the invasive procedure. For invasive procedures at high bleeding risk, it is suggested to interrupt rivaroxaban, apixaban and edoxaban three days before. Dabigatran should be interrupted according to the renal function, four days and five days if creatinine clearance is higher than 50mL/min and between 30 and 50mL/min, respectively. For invasive procedures at very high bleeding risk such as intracranial neurosurgery or neuraxial anesthesia, longer interruption times are suggested. Finally, bridging with parenteral anticoagulation and measurement of DOA concentrations can no longer routinely be used.
自 2011 年以来,积累了大量关于接受侵入性操作的患者接触直接口服抗凝剂(DOA)的数据。同时,围手术期桥接抗凝时出血风险增加,但血栓形成风险并未降低。这导致 GIHP 更新了他们在 2011 年发布的指南。对于低出血风险的计划手术,建议患者在手术前一天晚上中断 DOA,无论药物类型如何,并在侵入性手术结束后六小时或更长时间后恢复治疗。对于高出血风险的侵入性手术,建议在手术前三天中断利伐沙班、阿哌沙班和依度沙班。达比加群应根据肾功能中断,清除率高于 50mL/min 时分别中断四天和五天,清除率在 30 至 50mL/min 之间。对于颅内神经外科或脊柱麻醉等极高出血风险的侵入性手术,建议中断时间更长。最后,不再常规使用静脉内抗凝桥接和 DOA 浓度测量。
