Tranexamic acid (TXA) is an antifibrinolytic agent currently approved and utilized in the treatment of dysfunctional uterine bleeding, traumatic extracranial hemorrhage, anterior epistaxis, and dental procedures on patients with hemophilia. There is a paucity of literature evaluating the use of TXA for hemostasis in patients on direct oral anticoagulants (DOACs).
Our patient, a 72 year-old male on rivaroxaban, presented with persistent bleeding following a punch biopsy of the buccal mucosa. Given the site of bleeding, inability to effectively tamponade, patient's anticoagulated state, and risk of impending airway compromise, a dressing was soaked with 500 milligram (mg) of TXA and was held in place with pressure using a makeshift clamp until a thrombus formed. Hemostasis was achieved preventing the need for acute ENTotolaryngologic intervention and/or intubation. The patient was observed in the medical setting overnight and discharged home without any recurrence of bleeding or adverse events.
This case report describes our experience achieving hemostasis for an otherwise uncontrollable oral bleed in an anticoagulated patient on a DOAC who could not be reversed. Intervention is simple to perform, cost-effective, and requires few resources which are readily available in most emergency departments.
We report a novel application of TXA to control an oral mucosal bleed in an anticoagulated patient which was on a DOAC refractory to traditional measures.
氨甲环酸(TXA)是一种抗纤维蛋白溶解剂,目前已被批准用于治疗功能失调性子宫出血、外伤性颅外出血、鼻出血以及血友病患者的牙科手术。关于评估TXA在直接口服抗凝剂(DOACs)治疗患者中用于止血的文献较少。
我们的患者是一名72岁男性,正在服用利伐沙班,在颊黏膜穿刺活检后出现持续出血。考虑到出血部位、无法有效压迫止血、患者的抗凝状态以及即将出现气道受压的风险,将一块敷料用500毫克TXA浸湿,并用临时夹子加压固定,直到形成血栓。实现了止血,避免了急性耳鼻喉科干预和/或插管的需要。患者在医疗机构观察了一夜,出院回家,没有再出血或出现不良事件。
本病例报告描述了我们在一名无法逆转抗凝状态的DOAC治疗的抗凝患者中,成功实现对原本无法控制的口腔出血进行止血的经验。干预操作简单、成本效益高,且所需资源很少,大多数急诊科都 readily available。
我们报告了TXA在控制一名接受DOAC治疗且对传统措施难治的抗凝患者口腔黏膜出血方面的新应用。
