概括
将抗凝剂添加到早期外周动脉疾病 (PAD) 患者的抗血小板治疗中,这些患者正在接受下肢再血管化 (LER),这增加了重新干预和死亡风险. 这种组合疗法与PAD患者的1年治疗结果较差有关.
科学领域:
- 血管外科 血管外科
- 心脏病学 心脏病学
- 药理学 药理学是指药理学的学科.
背景情况:
- 过早的外周动脉疾病 (PAD),定义为50岁以下的下肢再血管化 (LER),与肢体不良事件有关.
- 早期发病的PAD可能涉及影响血管壁平衡和凝固的遗传因素.
- 在早发PAD中,与抗血小板治疗一起研究抗凝效应至关重要.
研究的目的:
- 评估添加抗血凝剂到抗血小板治疗对早发PAD患者LER结局的影响.
- 为了比较治疗组之间的再干预,重大截肢和死亡率.
主要方法:
- 分析了8,804名仅接受抗血小板治疗的患者与1,236名接受抗凝固加抗血小板治疗的患者,来自血管质量倡议.
- 倾向性得分匹配 (2:1) 以平衡基线特征.
- 评估术后和1年后的结果,包括重新干预,截肢和死亡率.
主要成果:
- 抗凝药患者有更多的并发症 (CAD,CHF) 和之前的LER,但不太常出院,不太可能使用他类药物.
- 在匹配后,抗凝剂与更高的手术室返回率 (3.7%对1.6%) 和术后死亡率 (1.1%对0.3%) 相关.
- 在抗凝血药群中,一年的无截肢生存率明显较低 (80.9%vs87.5%).
结论:
- 在接受LER的早发PAD患者中,结合抗血小板治疗的抗凝剂与增加的再干预和1年死亡率有关.
- 这些发现表明,在这种患者群体中使用联合抗凝血剂和抗血小板治疗时应谨慎.
- 进一步的研究可能会探索早期PAD的最佳抗血栓策略.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
408
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
