对长期口服抗凝剂治疗的患者拔牙,是一个有争议的问题。继续抗凝可使患者面临严重出血的危险,而停止或减少抗凝剂使用,则会使患者。尤其是人工心脏瓣膜的患者面临血栓栓塞的危险。过去对这些患者的拔牙,曾提出过许多方案;(1)继续治疗不改变抗凝作用。以前报告术后出血少或不出血的病例,多为凝血酶元肘间正常或在偏低的治疗范围值内,对较高的PT(凝血酶元时间)值者
Tooth extraction in patients treated with long-term oral anticoagulation is a matter of debate. Continued anticoagulation exposes patients to the risk of severe bleeding, while stopping or reducing the use of anticoagulants will result in patients. Patients with prosthetic heart valves in particular are at risk of thromboembolism. There have been many proposals for tooth extraction of these patients in the past; (1) continued treatment does not change the anticoagulant effect. Previously reported less or no bleeding after the operation of the case, most of the normal or low thrombin elbow in the treatment range, the value of the PT (thrombin time) value of those who
