An increasing number of patients presenting to the emergency department (ED) with life-threatening bleeding are using oral anticoagulants, such as warfarin, Factor IIa and Factor Xa inhibitors. Achieving rapid and controlled haemostasis is critically important to save the patient's life. This multidisciplinary consensus paper provides a systematic and pragmatic approach to the management of anticoagulated patients with severe bleeding at the ED. Repletion and reversal management of the specific anticoagulants is described in detail. For patients on vitamin K antagonists, the administration of vitamin K and repletion of clotting factors with four-factor prothrombin complex concentrate provides real-time ability to stop the bleeding. For patients using a direct oral anticoagulant, specific antidotes are necessary to reverse the anticoagulative effect. For patients receiving the thrombin inhibitor dabigatran, treatment with idarucizamab has been demonstrated to reverse the hypocoagulable state. For patients receiving a factor Xa inhibitor (apixaban or rivaroxaban), andexanet alfa is the indicated antidote in patients with major bleeding. Lastly, specific treatment strategies are discussed in patients using anticoagulants with major traumatic bleeding, intracranial haemorrhage or gastrointestinal bleeding.
越来越多因危及生命的出血而到急诊科就诊的患者正在使用口服抗凝剂,如华法林、凝血因子 IIa 和 Xa 抑制剂。实现快速和控制出血对于挽救患者生命至关重要。这份多学科共识文件为急诊科严重出血的抗凝患者的管理提供了一种系统和实用的方法。详细描述了特定抗凝剂的补充和逆转管理。对于接受维生素 K 拮抗剂治疗的患者,给予维生素 K 和四因子凝血酶原复合物浓缩物补充凝血因子可实时止血。对于使用直接口服抗凝剂的患者,需要使用特定的解毒剂来逆转抗凝作用。对于接受凝血酶抑制剂达比加群的患者,已证明idarucizumab可逆转低凝状态。对于接受因子 Xa 抑制剂(阿哌沙班或利伐沙班)的患者,andexanet alfa 是有大出血的患者的指征解毒剂。最后,讨论了在有大出血、颅内出血或胃肠道出血的抗凝患者中使用抗凝剂的具体治疗策略。
