概括
将血栓素注射到阳性大腿动脉伪动脉瘤 (IFP) 囊的中心,而不是接口,可以改善囊内血栓形成,并减少囊外危险的血栓. 缓慢,有意识的注射提高了治疗的有效性.
科学领域:
- 血管外科 血管外科
- 干预性放射学 干预性放射学
- 生物医学工程 生物医学工程
背景情况:
- 由于血管造影程序的增加,Iatrogenic大腿动脉伪动脉瘤 (IFP) 的发生率正在上升.
- 皮肤输血栓注射 (PTI) 是一种常见的,最少侵入性的IFP治疗方法.
- 有限的研究存在于优化PTI以尽量减少并发症和最大限度地提高疗效.
研究的目的:
- 在试验室中模拟IFP血栓形成.
- 分析血栓注射参数对囊内血栓和囊外血栓栓塞的影响.
主要方法:
- 在体外模型中使用猪血评估PTI.
- 多种类型的血栓注射部位 (结点,中心,圆顶).
- 测试的注射时间 (5秒和8秒) 和血液流速 (210-300毫升/分钟).
主要成果:
- 在囊中注射促进了完整的囊内血栓形成,减少了外部血栓.
- 在接口处注射导致内血栓的减少,但更多的外部血栓.
- 较长的注射时间提高了疗效,降低了血栓栓塞的风险.
- 较高的流速 (>240毫升/分钟) 增加了血栓栓塞的发生频率.
结论:
- 血栓激素注射部位严重影响血栓形成和血栓栓塞.
- 通过缓慢的,有意识的注射来准伪动脉瘤囊中心可能会提高PTI的疗效和安全性.

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
417
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.
